This will stop in the first function call in <a statement>. Alternatively, if a statement terminated with an unhandled exception, you can use pdb's post-mortem facility to inspect the contents of the traceback: >>> <a statement> <exception traceback> >>> import pdb >>> pdb.pm() The commands recognized by the debugger are listed in the next section. Most can be abbreviated as indicated; e.g., h(elp) means that 'help' can be typed as 'h' or 'help' (but not as 'he' or 'hel', nor as 'H' or 'Help' or 'HELP'). Optional arguments are enclosed in square brackets. Alternatives in the command syntax are separated by a vertical bar (|). A blank line repeats the previous command literally, except for 'list', where it lists the next 11 lines. Commands that the debugger doesn't recognize are assumed to be Python statements and are executed in the context of the program being debugged. Python statements can also be prefixed with an exclamation point ('!'). This is a powerful way to inspect the program being debugged; it is even possible to change variables or call functions. When an exception occurs in such a statement, the exception name is printed but the debugger's state is not changed. The debugger supports aliases, which can save typing. And aliases can have parameters (see the alias help entry) which allows one a certain level of adaptability to the context under examination. Multiple commands may be entered on a single line, separated by the pair ';;'. No intelligence is applied to separating the commands; the input is split at the first ';;', even if it is in the middle of a quoted string. If a file ".pdbrc" exists in your home directory or in the current directory, it is read in and executed as if it had been typed at the debugger prompt. This is particularly useful for aliases. If both files exist, the one in the home directory is read first and aliases defined there can be overridden by the local file. This behavior can be disabled by passing the "readrc=False" argument to the Pdb constructor. Aside from aliases, the debugger is not directly programmable; but it is implemented as a class from which you can derive your own debugger class, which you can make as fancy as you like.

(com) end (Pdb) Specify a list of commands for breakpoint number bpnumber. The commands themselves are entered on the following lines. Type a line containing just 'end' to terminate the commands. The commands are executed when the breakpoint is hit. To remove all commands from a breakpoint, type commands and follow it immediately with end; that is, give no commands. With no bpnumber argument, commands refers to the last breakpoint set. You can use breakpoint commands to start your program up again. Simply use the continue command, or step, or any other command that resumes execution. Specifying any command resuming execution (currently continue, step, next, return, jump, quit and their abbreviations) terminates the command list (as if that command was immediately followed by end). This is because any time you resume execution (even with a simple next or step), you may encounter another breakpoint -- which could have its own command list, leading to ambiguities about which list to execute. If you use the 'silent' command in the command list, the usual message about stopping at a breakpoint is not printed. This may be desirable for breakpoints that are to print a specific message and then continue. If none of the other commands print anything, you will see no sign that the breakpoint was reached. r z.Usage: commands [bnum] ... endNTFz(com) r r� z1command definition aborted, old commands restored)�lenr4 r� r� �intr� rM rI rJ rK r9 rL r� rQ )r. r� ZbnumZold_command_defsZ prompt_backr r r � do_commands s@ % zPdb.do_commandsr c C s@ |s<| j r8| jd� x"tjjD ]}|r | j|j� � q W dS d}d}d}|jd�}|dkr~||d d� j� }|d|� j� }|j d�}d} |dk�r|d|� j� }| j |�} | s�| j d| � dS | }||d d� j� }y t |�}W n$ t k �r | j d| � dS X n�y t |�}W n� t k �r� yt|| jj| j�} W n |} Y nX y.t| d ��rl| j} | j} | j} | j}| j}W n@ | j|�\} }}| �s�| j d | � dS | } t |�}Y nX Y nX |�s�| j� }| j||�}|�r<| j||||| �}|�r| j |� n*| j ||�d }| jd |j |j |j f � dS ) a� b(reak) [ ([filename:]lineno | function) [, condition] ] Without argument, list all breaks.

The command must *not* be enclosed in quotes. Replaceable parameters can be indicated by %1, %2, and so on, while %* is replaced by all the parameters. If no command is given, the current alias for name is shown. If no name is given, all aliases are listed. Aliases may be nested and can contain anything that can be legally typed at the pdb prompt. Note! You *can* override internal pdb commands with aliases! Those internal commands are then hidden until the alias is removed. Aliasing is recursively applied to the first word of the command line; all other words in the line are left alone. As an example, here are two useful aliases (especially when placed in the .pdbrc file): # Print instance variables (usage "pi classInst") alias pi for k in %1.__dict__.keys(): print("%1.",k,"=",%1.__dict__[k]) # Print instance variables in self alias ps pi self r z%s = %sNr r� )r� r� �sortedr: r� rR rG )r. r� r� r� r� r r r �do_aliasd s "z Pdb.do_aliasc C s6 |j � }t|�dkrdS |d | jkr2| j|d = dS )z9unalias name Delete the specified alias. r N)r� r� r: )r. r� r� r r r � do_unalias� s zPdb.do_unaliasc s � fdd�| j D �S )Nc s g | ]}|j � �r|�qS r )r� )r� �a)r� r r r� � s z(Pdb.complete_unalias.<locals>.<listcomp>)r: )r. r� r r� r� r )r� r �complete_unalias� s zPdb.complete_unaliasr r r r r r c C s8 y x| j D ]}| j|� q W W n tk r2 Y nX d S )N)rX rt rQ )r. � frame_linenor r r r � s zPdb.print_stack_tracec C s6 |\}}|| j krd}nd}| j|| j||� � d S )Nz> z )rZ rR Zformat_stack_entry)r. rI Z prompt_prefixrT r r� r r r rt � s zPdb.print_stack_entryc C s� |st jj| |�S y<yt| d| �}|� S tk rJ t| d| �}Y nX W n" tk rp | jd| � Y n0X tjjdkr�| jd| � dS | j |j j � � dS )z�h(elp) Without argument, print the list of available commands.

(Note that this module provides a Python version of the threading.local class. Depending on the version of Python you're using, there may be a faster one available. You should always import the `local` class from `threading`.) Thread-local objects support the management of thread-local data. If you have data that you want to be local to a thread, simply create a thread-local object and use its attributes: >>> mydata = local() >>> mydata.number = 42 >>> mydata.number 42 You can also access the local-object's dictionary: >>> mydata.__dict__ {'number': 42} >>> mydata.__dict__.setdefault('widgets', []) [] >>> mydata.widgets [] What's important about thread-local objects is that their data are local to a thread. If we access the data in a different thread: >>> log = [] >>> def f(): ... items = sorted(mydata.__dict__.items()) ... log.append(items) ... mydata.number = 11 ... log.append(mydata.number) >>> import threading >>> thread = threading.Thread(target=f) >>> thread.start() >>> thread.join() >>> log [[], 11] we get different data. Furthermore, changes made in the other thread don't affect data seen in this thread: >>> mydata.number 42 Of course, values you get from a local object, including a __dict__ attribute, are for whatever thread was current at the time the attribute was read. For that reason, you generally don't want to save these values across threads, as they apply only to the thread they came from. You can create custom local objects by subclassing the local class: >>> class MyLocal(local): ... number = 2 ... def __init__(self, **kw): ... self.__dict__.update(kw) ... def squared(self): ... return self.number ** 2 This can be useful to support default values, methods and initialization. Note that if you define an __init__ method, it will be called each time the local object is used in a separate thread. This is necessary to initialize each thread's dictionary. Now if we create a local object: >>> mydata = MyLocal(color='red') Now we have a default number: >>> mydata.number 2 an initial color: >>> mydata.color 'red' >>> del mydata.color And a method that operates on the data: >>> mydata.squared() 4 As before, we can access the data in a separate thread: >>> log = [] >>> thread = threading.Thread(target=f) >>> thread.start() >>> thread.join() >>> log [[('color', 'red')], 11] without affecting this thread's data: >>> mydata.number 2 >>> mydata.color Traceback (most recent call last): ... AttributeError: 'MyLocal' object has no attribute 'color' Note that subclasses can define slots, but they are not thread local. They are shared across threads: >>> class MyLocal(local): ... __slots__ = 'number' >>> mydata = MyLocal() >>> mydata.number = 42 >>> mydata.color = 'red' So, the separate thread: >>> thread = threading.Thread(target=f) >>> thread.start() >>> thread.join() affects what we see: >>> mydata.number 11 >>> del mydata � )�ref)�contextmanager�localc @ s, e Zd ZdZdZdd� Zd d � Zd d � Zd S )� _localimplz#A class managing thread-local dicts�key�dicts� localargs� locallock� __weakref__c C s dt t| �� | _i | _d S )Nz _threading_local._localimpl.)�str�idr r )�self� r �(/usr/lib64/python3.6/_threading_local.py�__init__� s z_localimpl.__init__c C s t � }| jt|� d S )zPReturn the dict for the current thread.

To enable this module, do: import cgitb; cgitb.enable() at the top of your script. The optional arguments to enable() are: display - if true, tracebacks are displayed in the web browser logdir - if set, tracebacks are written to files in this directory context - number of lines of source code to show for each stack frame format - 'text' or 'html' controls the output format By default, tracebacks are displayed but not saved, the context is 5 lines and the output format is 'html' (for backwards compatibility with the original use of this module) Alternatively, if you have caught an exception and want cgitb to display it for you, call cgitb.handler(). The optional argument to handler() is a 3-item tuple (etype, evalue, etb) just like the value of sys.exc_info(). The default handler displays output as HTML. � Nc C s dS )zAReturn a string that resets the CGI and browser to a known state.a' <!--: spam Content-Type: text/html <body bgcolor="#f0f0f8"><font color="#f0f0f8" size="-5"> --> <body bgcolor="#f0f0f8"><font color="#f0f0f8" size="-5"> --> --> </font> </font> </font> </script> </object> </blockquote> </pre> </table> </table> </table> </table> </table> </font> </font> </font>� r r r � /usr/lib64/python3.6/cgitb.py�reset# s r c C s | rd| d S dS d S )Nz<small>z</small>� r )�textr r r �small. s r c C s | rd| d S dS d S )Nz<strong>z </strong>r r )r r r r �strong4 s r c C s | rd| d S dS d S )Nz<font color="#909090">z</font>r r )r r r r �grey: s r c C s� | |krd|| fS | |j kr,d|j | fS d|j kr~|j d }t|�ti �krf| |kr~d|| fS nt|| �r~dt|| �fS dtfS )z9Find the value for a given name in the given environment.�local�global� __builtins__�builtinN)� f_globals�type�hasattr�getattr� __UNDEF__)�name�frame�locals�builtinsr r r �lookup@ s r c C s� g dddt f\}}}}}x�tj| �D ]�\}} } } } |tjkr>P |tjkr�| tjkr�|dkr�|t k r�t|| t �}|j|| ||f� q�t | ||�\} }|j| | |f� n"| dkr�||d 7 }|}nd\}}| }q$W |S )zEScan one logical line of Python and look up values of variables used.Nr �.)Nr ) r �tokenize�generate_tokens�NEWLINE�NAME�keyword�kwlistr �appendr )�readerr r �varsZ lasttoken�parent�prefix�valueZttype�token�start�end�line�wherer r r �scanvarsP s" r* � c " s� | \}}}t |t�r|j}dtjj� d d tj }tjtj� �}dt j j dt t j j t|��� dd|d | � d }d td d � d }g } tj||�} �xJ| D �]@\} � } } }}� r�tjj� �� d� t j j � �f }nd � }tj| �\}}}}d}| dk�r2dt t j j | �� tj||||dd� d� }i �| gf� �fdd� }t|| |�}dd||f g}|dk �r| | }x�|D ]�}td d tt|�� t|� �d }|�k�r�d|t j j|�f }|jd| � n&d |t j j|�f }|jd t|� � |d 7 }�q~W i g } } x�|D ]�\} } } | | k�r0�qd | | < | t k �r�| d-k�r^d!| t | � } n*| d"k�rrt | �} n| t | jd#�d. � } | jd$| t j j | �f � n| j| d% � �qW |jd ttd&j | ��� � | jd'd(j |� � q�W d)t t j j t|���t j j t|��f g}!xNt |�D ]B} | dd � d*k�r:�q t j j t || ��} |!jd+|| | f � �q W |dj | � dj |!� d,t j j dj t!j"|||��� S )/z9Return a nice HTML document describing a given traceback.zPython r z: z<body bgcolor="#f0f0f8">z<big><big>%s</big></big>z#ffffffz#6622aaz<br>z� <p>A problem occurred in a Python script.

Even though this function is called initlog(), you should always use log(); log is a variable that is set either to initlog (initially), to dolog (once the log file has been opened), or to nolog (when logging is disabled). The first argument is a format string; the remaining arguments (if any) are arguments to the % operator, so e.g. log("%s: %s", "a", "b") will write "a: b" to the log file, followed by a newline. If the global logfp is not None, it should be a file object to which log data is written. If the global logfp is None, the global logfile may be a string giving a filename to open, in append mode. This file should be world writable!!! If the file can't be opened, logging is silently disabled (since there is no safe place where we could send an error message). �aN)�logfile�logfp�open�OSError�nolog�log�dolog)�allargs� r" �/usr/lib64/python3.6/cgi.py�initlog: s r$ c G s t j| | d � dS )z=Write a log message to the log file.

Arguments: fp : input file pdict: dictionary containing other parameters of content-type header Returns a dictionary just like parse_qs(): keys are the field names, each value is a list of values for that field. This is easy to use but not much good if you are expecting megabytes to be uploaded -- in that case, use the FieldStorage class instead which is much more flexible. Note that content-type is the raw, unparsed contents of the content-type header. XXX This does not parse nested multipart parts -- use FieldStorage for that. XXX This should really be subsumed by FieldStorage altogether -- no point in having two implementations of the same parsing algorithm. Also, FieldStorage protects itself better against certain DoS attacks by limiting the size of the data read in one chunk. The API here does not support that kind of protection.

This class provides naming, typing, files stored on disk, and more. At the top level, it is accessible like a dictionary, whose keys are the field names. (Note: None can occur as a field name.) The items are either a Python list (if there's multiple values) or another FieldStorage or MiniFieldStorage object. If it's a single object, it has the following attributes: name: the field name, if specified; otherwise None filename: the filename, if specified; otherwise None; this is the client side filename, *not* the file name on which it is stored (that's a temporary file you don't deal with) value: the value as a *string*; for file uploads, this transparently reads the file every time you request the value and returns *bytes* file: the file(-like) object from which you can read the data *as bytes* ; None if the data is stored a simple string type: the content-type, or None if not specified type_options: dictionary of options specified on the content-type line disposition: content-disposition, or None if not specified disposition_options: dictionary of corresponding options headers: a dictionary(-like) object (sometimes email.message.Message or a subclass thereof) containing *all* headers The class is subclassable, mostly for the purpose of overriding the make_file() method, which is called internally to come up with a file open for reading and writing. This makes it possible to override the default choice of storing all files in a temporary directory and unlinking them as soon as they have been opened.

A true value indicates that blanks should be retained as blank strings. The default false value indicates that blank values are to be ignored and treated as if they were not included. strict_parsing: flag indicating what to do with parsing errors. If false (the default), errors are silently ignored. If true, errors raise a ValueError exception. limit : used internally to read parts of multipart/form-data forms, to exit from the reading loop when reached. It is the difference between the form content-length and the number of bytes already read encoding, errors : the encoding and error handler used to decode the binary stream to strings.

The file will be used as follows: - data is written to it - seek(0) - data is read from it The file is opened in binary mode for files, in text mode for other fields This version opens a temporary file for reading and writing, and immediately deletes (unlinks) it. The trick (on Unix!) is that the file can still be used, but it can't be opened by another process, and it will automatically be deleted when it is closed or when the current process terminates. If you want a more permanent file, you derive a class which overrides this method. If you want a visible temporary file that is nevertheless automatically deleted when the script terminates, try defining a __del__ method in a derived class which unlinks the temporary files you have created. zwb+zw+r% )r* �newlineN)r� �tempfileZ TemporaryFiler* )rq r" r" r# r� } s zFieldStorage.make_file)N)Ni )!rt ru rv rw �osrA rr r� r� r� rs r� r� r� r� r� r� r� r� r� r� r� r� r� r� r� r� r� r� r� r� r� r� r" r" r" r# r l s@ * " D 1c C s� t d� t � tjt_yNt� }t� t� t|� t| � t � dd� }|fdd�}t d� |� W n t � Y nX t d� da y&t� }t� t� t|� t| � W n t � Y nX d S ) z�Robust test CGI script, usable as main program.

This module provides immutable UUID objects (class UUID) and the functions uuid1(), uuid3(), uuid4(), uuid5() for generating version 1, 3, 4, and 5 UUIDs as specified in RFC 4122. If all you want is a unique ID, you should probably call uuid1() or uuid4(). Note that uuid1() may compromise privacy since it creates a UUID containing the computer's network address. uuid4() creates a random UUID. Typical usage: >>> import uuid # make a UUID based on the host ID and current time >>> uuid.uuid1() # doctest: +SKIP UUID('a8098c1a-f86e-11da-bd1a-00112444be1e') # make a UUID using an MD5 hash of a namespace UUID and a name >>> uuid.uuid3(uuid.NAMESPACE_DNS, 'python.org') UUID('6fa459ea-ee8a-3ca4-894e-db77e160355e') # make a random UUID >>> uuid.uuid4() # doctest: +SKIP UUID('16fd2706-8baf-433b-82eb-8c7fada847da') # make a UUID using a SHA-1 hash of a namespace UUID and a name >>> uuid.uuid5(uuid.NAMESPACE_DNS, 'python.org') UUID('886313e1-3b8a-5372-9b90-0c9aee199e5d') # make a UUID from a string of hex digits (braces and hyphens ignored) >>> x = uuid.UUID('{00010203-0405-0607-0809-0a0b0c0d0e0f}') # convert a UUID to a string of hex digits in standard form >>> str(x) '00010203-0405-0607-0809-0a0b0c0d0e0f' # get the raw 16 bytes of the UUID >>> x.bytes b'\x00\x01\x02\x03\x04\x05\x06\x07\x08\t\n\x0b\x0c\r\x0e\x0f' # make a UUID from a 16-byte string >>> uuid.UUID(bytes=x.bytes) UUID('00010203-0405-0607-0809-0a0b0c0d0e0f') � NzKa-Ping Yee <ping@zesty.ca>z reserved for NCS compatibilityzspecified in RFC 4122z$reserved for Microsoft compatibilityz reserved for future definitionc @ s e Zd ZdZd7dd�Zdd� Zdd� Zd d � Zd d � Zd d� Z dd� Z dd� Z dd� Z dd� Z dd� Zedd� �Zedd � �Zed d � �Zed d � �Zed!d"� �Zed#d$� �Zed%d&� �Zed'd(� �Zed)d*� �Zed+d,� �Zed-d.� �Zed/d0� �Zed1d2� �Z ed3d4� �Z ed5d6� �Z dS )8�UUIDa� Instances of the UUID class represent UUIDs as specified in RFC 4122. UUID objects are immutable, hashable, and usable as dictionary keys. Converting a UUID to a string with str() yields something in the form '12345678-1234-1234-1234-123456789abc'. The UUID constructor accepts five possible forms: a similar string of hexadecimal digits, or a tuple of six integer fields (with 32-bit, 16-bit, 16-bit, 8-bit, 8-bit, and 48-bit values respectively) as an argument named 'fields', or a string of 16 bytes (with all the integer fields in big-endian order) as an argument named 'bytes', or a string of 16 bytes (with the first three fields in little-endian order) as an argument named 'bytes_le', or a single 128-bit integer as an argument named 'int'. UUIDs have these read-only attributes: bytes the UUID as a 16-byte string (containing the six integer fields in big-endian byte order) bytes_le the UUID as a 16-byte string (with time_low, time_mid, and time_hi_version in little-endian byte order) fields a tuple of the six integer fields of the UUID, which are also available as six individual attributes and two derived attributes: time_low the first 32 bits of the UUID time_mid the next 16 bits of the UUID time_hi_version the next 16 bits of the UUID clock_seq_hi_variant the next 8 bits of the UUID clock_seq_low the next 8 bits of the UUID node the last 48 bits of the UUID time the 60-bit timestamp clock_seq the 14-bit sequence number hex the UUID as a 32-character hexadecimal string int the UUID as a 128-bit integer urn the UUID as a URN as specified in RFC 4122 variant the UUID variant (one of the constants RESERVED_NCS, RFC_4122, RESERVED_MICROSOFT, or RESERVED_FUTURE) version the UUID version number (1 through 5, meaningful only when the variant is RFC_4122) Nc C s� |||||gj d�dkr td��|dk rl|jdd�jdd�}|jd�jdd�}t|�d krbtd ��t|d �}|dk r�t|�d kr�td ��|d(dd)� |d*d+d,� |d-d.d/� |dd� }|dk �rt|�d kr�td��t|t�� s�t t |���tj |dd�}|dk �r:t|�dk�r"td��|\}}} } } } d| k�oFd0k n �sVtd��d| k�ojd1k n �sztd��d| k�o�d2k n �s�td��d| k�o�d3k n �s�td��d| k�o�d4k n �s�td��d| k�o�d5k n �s td��| d> | B } |d > |d > B | d > B | d> B | B }|dk �rld| k�o\d d > k n �sltd ��|dk �r�d | k�o�d!kn �s�td"��|d7M }|d8O }|d:M }||d&> O }|| j d'< dS );am Create a UUID from either a string of 32 hexadecimal digits, a string of 16 bytes as the 'bytes' argument, a string of 16 bytes in little-endian order as the 'bytes_le' argument, a tuple of six integers (32-bit time_low, 16-bit time_mid, 16-bit time_hi_version, 8-bit clock_seq_hi_variant, 8-bit clock_seq_low, 48-bit node) as the 'fields' argument, or a single 128-bit integer as the 'int' argument. When a string of hex digits is given, curly braces, hyphens, and a URN prefix are all optional. For example, these expressions all yield the same UUID: UUID('{12345678-1234-5678-1234-567812345678}') UUID('12345678123456781234567812345678') UUID('urn:uuid:12345678-1234-5678-1234-567812345678') UUID(bytes='\x12\x34\x56\x78'*4) UUID(bytes_le='\x78\x56\x34\x12\x34\x12\x78\x56' + '\x12\x34\x56\x78\x12\x34\x56\x78') UUID(fields=(0x12345678, 0x1234, 0x5678, 0x12, 0x34, 0x567812345678)) UUID(int=0x12345678123456781234567812345678) Exactly one of 'hex', 'bytes', 'bytes_le', 'fields', or 'int' must be given.

Opcodes that operate on a variable number of objects generally don't embed the count of objects in the opcode, or pull it off the stack. Instead the MARK opcode is used to push a special marker object on the stack, and then some other opcodes grab all the objects from the top of the stack down to (but not including) the topmost marker object. � stackslicea� An object representing a contiguous slice of the stack. This is used in conjunction with markobject, to represent all of the stack following the topmost markobject. For example, the POP_MARK opcode changes the stack from [..., markobject, stackslice] to [...] No matter how many object are on the stack after the topmost markobject, POP_MARK gets rid of all of them (including the topmost markobject too). c @ s e Zd Zd Zdd � Zd S ) � OpcodeInfor �code�arg� stack_before� stack_after�protor c C sJ || _ || _|| _x |D ]}qW || _x |D ]}q,W || _|| _|| _d S )N)r rr rs rt ru rv r ) r r rr rs rt ru rv r �xr r r r T s zOpcodeInfo.__init__N)r rr rs rt ru rv r )r r r r r r r r r rq 5 s rq ZINT�Ia� Push an integer or bool. The argument is a newline-terminated decimal literal string. The intent may have been that this always fit in a short Python int, but INT can be generated in pickles written on a 64-bit box that require a Python long on a 32-bit box. The difference between this and LONG then is that INT skips a trailing 'L', and produces a short int whenever possible. Another difference is due to that, when bool was introduced as a distinct type in 2.3, builtin names True and False were also added to 2.2.2, mapping to ints 1 and 0. For compatibility in both directions, True gets pickled as INT + "I01\n", and False as INT + "I00\n". Leading zeroes are never produced for a genuine integer. The 2.3 (and later) unpicklers special-case these and return bool instead; earlier unpicklers ignore the leading "0" and return the int. )r rr rs rt ru rv r ZBININT�Ja1 Push a four-byte signed integer. This handles the full range of Python (short) integers on a 32-bit box, directly as binary bytes (1 for the opcode and 4 for the integer). If the integer is non-negative and fits in 1 or 2 bytes, pickling via BININT1 or BININT2 saves space. ZBININT1�Kz�Push a one-byte unsigned integer. This is a space optimization for pickling very small non-negative ints, in range(256). ZBININT2�Mz�Push a two-byte unsigned integer. This is a space optimization for pickling small positive ints, in range(256, 2**16). Integers in range(256) can also be pickled via BININT2, but BININT1 instead saves a byte. ZLONG�La� Push a long integer. The same as INT, except that the literal ends with 'L', and always unpickles to a Python long. There doesn't seem a real purpose to the trailing 'L'. Note that LONG takes time quadratic in the number of digits when unpickling (this is simply due to the nature of decimal->binary conversion). Proto 2 added linear-time (in C; still quadratic-time in Python) LONG1 and LONG4 opcodes. ZLONG1� z|Long integer using one-byte length. A more efficient encoding of a Python long; the long1 encoding says it all.ZLONG4� z~Long integer using found-byte length. A more efficient encoding of a Python long; the long4 encoding says it all.�STRING�Sa� Push a Python string object. The argument is a repr-style string, with bracketing quote characters, and perhaps embedded escapes. The argument extends until the next newline character. These are usually decoded into a str instance using the encoding given to the Unpickler constructor. or the default, 'ASCII'. If the encoding given was 'bytes' however, they will be decoded as bytes object instead. Z BINSTRING�Ta� Push a Python string object. There are two arguments: the first is a 4-byte little-endian signed int giving the number of bytes in the string, and the second is that many bytes, which are taken literally as the string content. These are usually decoded into a str instance using the encoding given to the Unpickler constructor. or the default, 'ASCII'. If the encoding given was 'bytes' however, they will be decoded as bytes object instead. ZSHORT_BINSTRING�Ua� Push a Python string object. There are two arguments: the first is a 1-byte unsigned int giving the number of bytes in the string, and the second is that many bytes, which are taken literally as the string content. These are usually decoded into a str instance using the encoding given to the Unpickler constructor. or the default, 'ASCII'. If the encoding given was 'bytes' however, they will be decoded as bytes object instead. ZBINBYTES�Bz�Push a Python bytes object. There are two arguments: the first is a 4-byte little-endian unsigned int giving the number of bytes, and the second is that many bytes, which are taken literally as the bytes content. ZSHORT_BINBYTES�Cz�Push a Python bytes object. There are two arguments: the first is a 1-byte unsigned int giving the number of bytes, and the second is that many bytes, which are taken literally as the string content. Z BINBYTES8� z�Push a Python bytes object. There are two arguments: the first is an 8-byte unsigned int giving the number of bytes in the string, and the second is that many bytes, which are taken literally as the string content. ZNONE�NzPush None on the stack.ZNEWTRUE� zPush True onto the stack.ZNEWFALSE� zPush False onto the stack.�UNICODE�Vz�Push a Python Unicode string object. The argument is a raw-unicode-escape encoding of a Unicode string, and so may contain embedded escape sequences. The argument extends until the next newline character. ZSHORT_BINUNICODE� a Push a Python Unicode string object. There are two arguments: the first is a 1-byte little-endian signed int giving the number of bytes in the string. The second is that many bytes, and is the UTF-8 encoding of the Unicode string. Z BINUNICODE�Xa Push a Python Unicode string object. There are two arguments: the first is a 4-byte little-endian unsigned int giving the number of bytes in the string. The second is that many bytes, and is the UTF-8 encoding of the Unicode string. Z BINUNICODE8� a Push a Python Unicode string object. There are two arguments: the first is an 8-byte little-endian signed int giving the number of bytes in the string. The second is that many bytes, and is the UTF-8 encoding of the Unicode string. ZFLOAT�Fa� Newline-terminated decimal float literal. The argument is repr(a_float), and in general requires 17 significant digits for roundtrip conversion to be an identity (this is so for IEEE-754 double precision values, which is what Python float maps to on most boxes). In general, FLOAT cannot be used to transport infinities, NaNs, or minus zero across boxes (or even on a single box, if the platform C library can't read the strings it produces for such things -- Windows is like that), but may do less damage than BINFLOAT on boxes with greater precision or dynamic range than IEEE-754 double. ZBINFLOAT�Ga� Float stored in binary form, with 8 bytes of data. This generally requires less than half the space of FLOAT encoding. In general, BINFLOAT cannot be used to transport infinities, NaNs, or minus zero, raises an exception if the exponent exceeds the range of an IEEE-754 double, and retains no more than 53 bits of precision (if there are more than that, "add a half and chop" rounding is used to cut it back to 53 significant bits).

For example, Stack before: ... markobject 1 2 3 'abc' Stack after: ... (1, 2, 3, 'abc') ZTUPLE1� z�Build a one-tuple out of the topmost item on the stack. This code pops one value off the stack and pushes a tuple of length 1 whose one item is that value back onto it. In other words: stack[-1] = tuple(stack[-1:]) ZTUPLE2� a Build a two-tuple out of the top two items on the stack. This code pops two values off the stack and pushes a tuple of length 2 whose items are those values back onto it. In other words: stack[-2:] = [tuple(stack[-2:])] ZTUPLE3� a Build a three-tuple out of the top three items on the stack. This code pops three values off the stack and pushes a tuple of length 3 whose items are those values back onto it. In other words: stack[-3:] = [tuple(stack[-3:])] Z EMPTY_DICT�}zPush an empty dict.ZDICT�da� Build a dict out of the topmost stack slice, after markobject. All the stack entries following the topmost markobject are placed into a single Python dict, which single dict object replaces all of the stack from the topmost markobject onward. The stack slice alternates key, value, key, value, .... For example, Stack before: ... markobject 1 2 3 'abc' Stack after: ... {1: 2, 3: 'abc'} ZSETITEMrS z�Add a key+value pair to an existing dict. Stack before: ... pydict key value Stack after: ... pydict where pydict has been modified via pydict[key] = value. ZSETITEMS�ua\ Add an arbitrary number of key+value pairs to an existing dict. The slice of the stack following the topmost markobject is taken as an alternating sequence of keys and values, added to the dict immediately under the topmost markobject. Everything at and after the topmost markobject is popped, leaving the mutated dict at the top of the stack. Stack before: ... pydict markobject key_1 value_1 ... key_n value_n Stack after: ... pydict where pydict has been modified via pydict[key_i] = value_i for i in 1, 2, ..., n, and in that order. Z EMPTY_SET� zPush an empty set.ZADDITEMS� a$ Add an arbitrary number of items to an existing set. The slice of the stack following the topmost markobject is taken as a sequence of items, added to the set immediately under the topmost markobject. Everything at and after the topmost markobject is popped, leaving the mutated set at the top of the stack. Stack before: ... pyset markobject item_1 ... item_n Stack after: ... pyset where pyset has been modified via pyset.add(item_i) = item_i for i in 1, 2, ..., n, and in that order. Z FROZENSET� az Build a frozenset out of the topmost slice, after markobject. All the stack entries following the topmost markobject are placed into a single Python frozenset, which single frozenset object replaces all of the stack from the topmost markobject onward. For example, Stack before: ... markobject 1 2 3 Stack after: ... frozenset({1, 2, 3}) �POP�0z<Discard the top stack item, shrinking the stack by one item.ZDUP�2z=Push the top stack item onto the stack again, duplicating it.�MARK�(z�Push markobject onto the stack. markobject is a unique object, used by other opcodes to identify a region of the stack containing a variable number of objects for them to work on. See markobject.doc for more detail. ZPOP_MARK�1a Pop all the stack objects at and above the topmost markobject. When an opcode using a variable number of stack objects is done, POP_MARK is used to remove those objects, and to remove the markobject that delimited their starting position on the stack. �GET�gz�Read an object from the memo and push it on the stack. The index of the memo object to push is given by the newline-terminated decimal string following. BINGET and LONG_BINGET are space-optimized versions. �BINGET�hz�Read an object from the memo and push it on the stack. The index of the memo object to push is given by the 1-byte unsigned integer following. � LONG_BINGET�jz�Read an object from the memo and push it on the stack. The index of the memo object to push is given by the 4-byte unsigned little-endian integer following. �PUT�pz�Store the stack top into the memo. The stack is not popped. The index of the memo location to write into is given by the newline- terminated decimal string following. BINPUT and LONG_BINPUT are space-optimized versions. �BINPUTr5 z�Store the stack top into the memo. The stack is not popped. The index of the memo location to write into is given by the 1-byte unsigned integer following. � LONG_BINPUT�rz�Store the stack top into the memo. The stack is not popped. The index of the memo location to write into is given by the 4-byte unsigned little-endian integer following. �MEMOIZE� z�Store the stack top into the memo. The stack is not popped. The index of the memo location to write is the number of elements currently present in the memo. ZEXT1� a� Extension code. This code and the similar EXT2 and EXT4 allow using a registry of popular objects that are pickled by name, typically classes. It is envisioned that through a global negotiation and registration process, third parties can set up a mapping between ints and object names. In order to guarantee pickle interchangeability, the extension code registry ought to be global, although a range of codes may be reserved for private use. EXT1 has a 1-byte integer argument. This is used to index into the extension registry, and the object at that index is pushed on the stack. ZEXT2� zNExtension code. See EXT1. EXT2 has a two-byte integer argument. ZEXT4� zOExtension code. See EXT1. EXT4 has a four-byte integer argument. ZGLOBAL�ca� Push a global object (module.attr) on the stack. Two newline-terminated strings follow the GLOBAL opcode. The first is taken as a module name, and the second as a class name. The class object module.class is pushed on the stack. More accurately, the object returned by self.find_class(module, class) is pushed on the stack, so unpickling subclasses can override this form of lookup. Z STACK_GLOBAL� z7Push a global object (module.attr) on the stack. ZREDUCE�RaL Push an object built from a callable and an argument tuple. The opcode is named to remind of the __reduce__() method. Stack before: ... callable pytuple Stack after: ... callable(*pytuple) The callable and the argument tuple are the first two items returned by a __reduce__ method. Applying the callable to the argtuple is supposed to reproduce the original object, or at least get it started. If the __reduce__ method returns a 3-tuple, the last component is an argument to be passed to the object's __setstate__, and then the REDUCE opcode is followed by code to create setstate's argument, and then a BUILD opcode to apply __setstate__ to that argument. If not isinstance(callable, type), REDUCE complains unless the callable has been registered with the copyreg module's safe_constructors dict, or the callable has a magic '__safe_for_unpickling__' attribute with a true value. I'm not sure why it does this, but I've sure seen this complaint often enough when I didn't want to <wink>. ZBUILD�ba� Finish building an object, via __setstate__ or dict update. Stack before: ... anyobject argument Stack after: ... anyobject where anyobject may have been mutated, as follows: If the object has a __setstate__ method, anyobject.__setstate__(argument) is called. Else the argument must be a dict, the object must have a __dict__, and the object is updated via anyobject.__dict__.update(argument) ZINST�iaq Build a class instance. This is the protocol 0 version of protocol 1's OBJ opcode. INST is followed by two newline-terminated strings, giving a module and class name, just as for the GLOBAL opcode (and see GLOBAL for more details about that). self.find_class(module, name) is used to get a class object. In addition, all the objects on the stack following the topmost markobject are gathered into a tuple and popped (along with the topmost markobject), just as for the TUPLE opcode. Now it gets complicated. If all of these are true: + The argtuple is empty (markobject was at the top of the stack at the start). + The class object does not have a __getinitargs__ attribute. then we want to create an old-style class instance without invoking its __init__() method (pickle has waffled on this over the years; not calling __init__() is current wisdom). In this case, an instance of an old-style dummy class is created, and then we try to rebind its __class__ attribute to the desired class object. If this succeeds, the new instance object is pushed on the stack, and we're done. Else (the argtuple is not empty, it's not an old-style class object, or the class object does have a __getinitargs__ attribute), the code first insists that the class object have a __safe_for_unpickling__ attribute. Unlike as for the __safe_for_unpickling__ check in REDUCE, it doesn't matter whether this attribute has a true or false value, it only matters whether it exists (XXX this is a bug). If __safe_for_unpickling__ doesn't exist, UnpicklingError is raised. Else (the class object does have a __safe_for_unpickling__ attr), the class object obtained from INST's arguments is applied to the argtuple obtained from the stack, and the resulting instance object is pushed on the stack. NOTE: checks for __safe_for_unpickling__ went away in Python 2.3. NOTE: the distinction between old-style and new-style classes does not make sense in Python 3. ZOBJ�oa� Build a class instance. This is the protocol 1 version of protocol 0's INST opcode, and is very much like it. The major difference is that the class object is taken off the stack, allowing it to be retrieved from the memo repeatedly if several instances of the same class are created. This can be much more efficient (in both time and space) than repeatedly embedding the module and class names in INST opcodes. Unlike INST, OBJ takes no arguments from the opcode stream. Instead the class object is taken off the stack, immediately above the topmost markobject: Stack before: ... markobject classobject stackslice Stack after: ... new_instance_object As for INST, the remainder of the stack above the markobject is gathered into an argument tuple, and then the logic seems identical, except that no __safe_for_unpickling__ check is done (XXX this is a bug). See INST for the gory details. NOTE: In Python 2.3, INST and OBJ are identical except for how they get the class object. That was always the intent; the implementations had diverged for accidental reasons. ZNEWOBJ� aL Build an object instance. The stack before should be thought of as containing a class object followed by an argument tuple (the tuple being the stack top). Call these cls and args. They are popped off the stack, and the value returned by cls.__new__(cls, *args) is pushed back onto the stack. Z NEWOBJ_EX� au Build an object instance. The stack before should be thought of as containing a class object followed by an argument tuple and by a keyword argument dict (the dict being the stack top). Call these cls and args. They are popped off the stack, and the value returned by cls.__new__(cls, *args, *kwargs) is pushed back onto the stack. �PROTO� z�Protocol version indicator. For protocol 2 and above, a pickle must start with this opcode. The argument is the protocol version, an int in range(2, 256). ZSTOP�.z�Stop the unpickling machine. Every pickle ends with this opcode. The object at the top of the stack is popped, and that's the result of unpickling. The stack should be empty then. �FRAME� z�Indicate the beginning of a new frame. The unpickler may use this opcode to safely prefetch data from its underlying stream. ZPERSID�Pa Push an object identified by a persistent ID. The pickle module doesn't define what a persistent ID means. PERSID's argument is a newline-terminated str-style (no embedded escapes, no bracketing quote characters) string, which *is* "the persistent ID". The unpickler passes this string to self.persistent_load(). Whatever object that returns is pushed on the stack. There is no implementation of persistent_load() in Python's unpickler: it must be supplied by an unpickler subclass. Z BINPERSID�QaX Push an object identified by a persistent ID. Like PERSID, except the persistent ID is popped off the stack (instead of being a string embedded in the opcode bytestream). The persistent ID is passed to self.persistent_load(), and whatever object that returns is pushed on the stack. See PERSID for more detail. z%repeated name %r at indices %d and %dz%repeated code %r at indices %d and %dFc C s t j� }x�tjD ]�}tjd|�s2| rtd| � qtt|�}t|t � sTt |�dkrj| rtd||f � q|j d�}||kr�| r�td||f � || }|j |kr�t d|||j f ��||= qt d||f ��qW |�rd g}x(|j� D ] \}}|jd |j |f � q�W t d j|���d S ) Nz[A-Z][A-Z0-9_]+$z0skipping %r: it doesn't look like an opcode namer z5skipping %r: value %r doesn't look like a pickle codezlatin-1z+checking name %r w/ code %r for consistencyzBfor pickle code %r, pickle.py uses name %r but we're using name %rzPpickle.py appears to have a pickle opcode with name %r and code %r, but we don'tz=we appear to have pickle opcodes that pickle.py doesn't have:z name %r with code %r� )�code2op�copy�pickle�__all__�re�match�print�getattrre ri r r3 r r �items�append�join)�verboser� r Z picklecoder� �msgrr r r r �assure_pickle_consistency s> r� c c s� t | t�rtj| �} t| d�r&| j}ndd� }x�|� }| jd�}tj|j d��}|d kr�|dkrjt d��n t d|d krzd n||f ��|j d kr�d }n |j j | �}|r�||||� fV n |||fV |d kr0P q0W d S ) N�tellc S s d S )Nr r r r r �<lambda>� s z_genops.<locals>.<lambda>r zlatin-1� z#pickle exhausted before seeing STOPz!at position %s, opcode %r unknownz <unknown>� .) re � bytes_types�io�BytesIO�hasattrr� r r� �getr3 r rs r )r � yield_end_posZgetpos�posrr �opcoders r r r �_genops� s. r� c C s t | �S )ax Generate all the opcodes in a pickle. 'pickle' is a file-like object, or string, containing the pickle. Each opcode in the pickle is generated, from the current pickle position, stopping after a STOP opcode is delivered. A triple is generated for each opcode: opcode, arg, pos opcode is an OpcodeInfo record, describing the current opcode. If the opcode has an argument embedded in the pickle, arg is its decoded value, as a Python object. If the opcode doesn't have an argument, arg is None. If the pickle has a tell() method, pos was the value of pickle.tell() before reading the current opcode. If the pickle is a bytes object, it's wrapped in a BytesIO object, and the latter's tell() result is used. Else (the pickle doesn't have a tell(), and it's not obvious how to query its current position) pos is None. )r� )r� r r r r � s c C s� d}d}t � }i }g }d}d}x�t| dd�D ]�\}} } } d|jkr\|j| � |j|| f� q,|jdkr�t|�} |j| � |j|| f� q,d|jkr�q,d|jkr�|j|kr�|j}d || < |j|| f� q,|jd k�r| |kr�| }| dkr�| | | � }n|j| | f� q,|j| | f� q,W ~tj� } | j |� t j | |�}|d k�rJ|j j � d} x�|D ]x\}} ||k�r�| |k�rt�qT|j| �}| || < | d 7 } n&||k�r�|j|| �}n | || � }|j j� |j |� �qTW |j j� | j� S ) z7Optimize a pickle string by removing unused PUT opcodesr� r� r r� T)r� r� r� Nr� r r )rm r� r �addr� r rv r� r� �writer� Z_PicklerZframerZ start_framing�putr� Z commit_frameZ end_framing�getvalue)r� r� r� ZoldidsZnewids�opcodesrv Z protoheaderr� rs r� Zend_pos�idx�outZpickler�opr r r r r � sd c C s g }|dkri }d }g }d| }d} |} �x�t | �D �]�\} } } | dk rZtd| d|d� dt| j�dd � |t|� | jf }t|| j�}| j}| j }t|�}d}t |ks�| jdko�|o�|d! t k�rD|�r<|j � }|dkr�d}nd | }x|d" t k �r|j � q�W |j � y|j t �}W n t k �r8 d }Y nX nd } }| jd#k�r�| jdk�rnt|�}d| }n| }||k�r�d| } n,|�s�d} n |d$ t k�r�d} n |d% ||< n*| jd&k�r�| |k�r�|| g}nd| } | dk �s�|�r0|ddt| j� 7 }| dk �r |dt| � 7 }|�r0|d| 7 }|�rz|d| t|� 7 }t|�} | dk�r`|} |d| jjdd�d 7 }t||d� | �r�t | ��t|�|k �r�t d |t|�f ��|�r�|| d�= t |k�r�|j| � |j|� q4W td ||d� |�r t d | ��dS )'aK Produce a symbolic disassembly of a pickle. 'pickle' is a file-like object, or string, containing a (at least one) pickle. The pickle is disassembled from the current position, through the first STOP opcode encountered. Optional arg 'out' is a file-like object to which the disassembly is printed. It defaults to sys.stdout. Optional arg 'memo' is a Python dict, used as the pickle's memo. It may be mutated by dis(), if the pickle contains PUT or BINPUT opcodes. Passing the same memo object to another dis() call then allows disassembly to proceed across multiple pickles that were all created by the same pickler with the same memo. Ordinarily you don't need to worry about this. Optional arg 'indentlevel' is the number of blanks by which to indent a new MARK level. It defaults to 4. Optional arg 'annotate' if nonzero instructs dis() to add short description of the opcode on each line of disassembled output. The value given to 'annotate' must be an integer and is used as a hint for the column where annotation should start. The default value is 0, meaning no annotations. In addition to printing the disassembly, some sanity checks are made: + All embedded opcode arguments "make sense". + Explicit and implicit pop operations have enough items on the stack. + When an opcode implicitly refers to a markobject, a markobject is actually on the stack. + A memo entry isn't referenced before it's defined. + The markobject isn't stored in the memo. + A memo entry isn't redefined.

OptionParser instances should use one of the HelpFormatter subclasses for formatting help; by default IndentedHelpFormatter is used. Instance attributes: parser : OptionParser the controlling OptionParser instance indent_increment : int the number of columns to indent per nesting level max_help_position : int the maximum starting column for option help text help_position : int the calculated starting column for option help text; initially the same as the maximum width : int total number of columns for output (pass None to constructor for this value to be taken from the $COLUMNS environment variable) level : int current indentation level current_indent : int current indentation level (in columns) help_width : int number of columns available for option help text (calculated) default_tag : str text to replace with each option's default value, "%default" by default. Set to false value to disable default value expansion. option_strings : { Option : str } maps Option instances to the snippet of help text explaining the syntax of that option, e.g. "-h, --help" or "-fFILE, --file=FILE" _short_opt_fmt : str format string controlling how short options with values are printed in help text. Must be either "%s%s" ("-fFILE") or "%s %s" ("-f FILE"), because those are the two syntaxes that Optik supports. _long_opt_fmt : str similar but for long options; must be either "%s %s" ("--file FILE") or "%s=%s" ("--file=FILE").

"-f" or "-X", to the Option instances that implement them. If an Option has multiple short option strings, it will appear in this dictionary multiple times.

Instance attributes: usage : string a usage string for your program. Before it is displayed to the user, "%prog" will be expanded to the name of your program (self.prog or os.path.basename(sys.argv[0])). prog : string the name of the current program (to override os.path.basename(sys.argv[0])). description : string A paragraph of text giving a brief overview of your program. optparse reformats this paragraph to fit the current terminal width and prints it when the user requests help (after usage, but before the list of options). epilog : string paragraph of help text to print after option help option_groups : [OptionGroup] list of option groups in this parser (option groups are irrelevant for parsing the command-line, but very useful for generating help) allow_interspersed_args : bool = true if true, positional arguments may be interspersed with options. Assuming -a and -b each take a single argument, the command-line -ablah foo bar -bboo baz will be interpreted the same as -ablah -bboo -- foo bar baz If this flag were false, that command line would be interpreted as -ablah -- foo bar -bboo baz -- ie. we stop processing options as soon as we see the first non-option argument. (This is the tradition followed by Python's getopt module, Perl's Getopt::Std, and other argument- parsing libraries, but it is generally annoying to users.) process_default_values : bool = true if true, option default values are processed similarly to option values from the command line: that is, they are passed to the type-checking function for the option's type (as long as the default value is a string). (This really only matters if you have defined custom types; see SF bug #955889.) Set it to false to restore the behaviour of Optik 1.4.1 and earlier. rargs : [string] the argument list currently being parsed. Only set when parse_args() is active, and continually trimmed down as we consume arguments. Mainly there for the benefit of callback options. largs : [string] the list of leftover arguments that we have skipped while parsing options. If allow_interspersed_args is false, this list is always empty. values : Values the set of option values currently being accumulated. Only set when parse_args() is active. Also mainly for callbacks. Because of the 'rargs', 'largs', and 'values' attributes, OptionParser is not thread-safe. If, for some perverse reason, you need to parse command-line arguments simultaneously in different threads, use different OptionParser instances.

On success returns a pair (values, args) where 'values' is a Values instance (with all your option values) and 'args' is the list of arguments left over after parsing options.

It decodes the bytes according to PEP-0263 for determining source file encoding. It accepts a readline-like method which is called repeatedly to get the next line of input (or b"" for EOF). It generates 5-tuples with these members: the token type (see token.py) the token (a string) the starting (row, column) indices of the token (a 2-tuple of ints) the ending (row, column) indices of the token (a 2-tuple of ints) the original line (string) It is designed to match the working of the Python tokenizer exactly, except that it produces COMMENT tokens for comments and gives type OP for all operators. Additionally, all token lists start with an ENCODING token which tells you which encoding was used to decode the bytes stream. zKa-Ping Yee <ping@lfw.org>zpGvR, ESR, Tim Peters, Thomas Wouters, Fred Drake, Skip Montanaro, Raymond Hettinger, Trent Nelson, Michael Foord� )�open)�lookup�BOM_UTF8N)� TextIOWrapper)�chain)�*z&^[ \t\f]*#.*?coding[:=][ \t]*([-\w.]+)s ^[ \t\f]*(?:[#\r\n]|$)�COMMENT�tokenize�detect_encoding�NL� untokenize�ENCODING� TokenInfo� � � ),�(�)�[�]�:�,�;�+�-r �/�|�&�<�>�=�.�%�{�}z==z!=z<=z>=�~�^z<<z>>z**z+=z-=z*=z/=z%=z&=z|=z^=z<<=z>>=z**=z//z//=�@z@=c @ s e Zd Zdd� Zedd� �ZdS )r c C s$ d| j t| j f }d| j|d� S )Nz%d (%s)z8TokenInfo(type=%s, string=%r, start=%r, end=%r, line=%r))�type)r( �tok_name�_replace)�self�annotated_type� r- � /usr/lib64/python3.6/tokenize.py�__repr__d s zTokenInfo.__repr__c C s( | j tkr | jtkr t| j S | j S d S )N)r( �OP�string�EXACT_TOKEN_TYPES)r+ r- r- r. � exact_typei s zTokenInfo.exact_typeN)�__name__� __module__� __qualname__r/ �propertyr3 r- r- r- r. r c s ztype string start end linec G s ddj | � d S )Nr r r )�join)�choicesr- r- r. �groupp s r: c G s t | � d S )Nr )r: )r9 r- r- r. �anyq s r; c G s t | � d S )N�?)r: )r9 r- r- r. �mayber s r= z[ \f\t]*z #[^\r\n]*z\\\r?\nz\w+z0[xX](?:_?[0-9a-fA-F])+z0[bB](?:_?[01])+z0[oO](?:_?[0-7])+z (?:0(?:_?0)*|[1-9](?:_?[0-9])*)z[eE][-+]?[0-9](?:_?[0-9])*z)[0-9](?:_?[0-9])*\.(?:[0-9](?:_?[0-9])*)?z\.[0-9](?:_?[0-9])*z[0-9](?:_?[0-9])*z[0-9](?:_?[0-9])*[jJ]z[jJ]c C sn ddddddg} t dg�}xN| D ]F}x@tj|�D ]2}x,tjdd � |D �� D ]}|jdj|�� qJW q0W q W |S ) N�b�r�u�f�br�fr� c S s g | ]}||j � f�qS r- )�upper)�.0�cr- r- r. � <listcomp>� s z(_all_string_prefixes.<locals>.<listcomp>)�set� _itertools� permutations�product�addr8 )�_valid_string_prefixes�result�prefix�tr@ r- r- r. �_all_string_prefixes� s rR c C s t j| t j�S )N)�re�compile�UNICODE)�exprr- r- r. �_compile� s rW z[^'\\]*(?:\\.[^'\\]*)*'z[^"\\]*(?:\\.[^"\\]*)*"z%[^'\\]*(?:(?:\\.|'(?!''))[^'\\]*)*'''z%[^"\\]*(?:(?:\\.|"(?!""))[^"\\]*)*"""z'''z"""z '[^\n'\\]*(?:\\.[^\n'\\]*)*'z "[^\n"\\]*(?:\\.[^\n"\\]*)*"z\*\*=?z>>=?z<<=?z!=z//=?z->z[+\-*/%&@|^=<>]=?r% z[][(){}]z\r?\nz\.\.\.z[:;.,@]z'[^\n'\\]*(?:\\.[^\n'\\]*)*�'z"[^\n"\\]*(?:\\.[^\n"\\]*)*�"z \\\r?\n|\Z� c @ s e Zd ZdS )� TokenErrorN)r4 r5 r6 r- r- r- r. r[ � s r[ c @ s e Zd ZdS )�StopTokenizingN)r4 r5 r6 r- r- r- r. r\ � s r\ c @ s, e Zd Zdd� Zdd� Zdd� Zdd� Zd S ) � Untokenizerc C s g | _ d| _d| _d | _d S )Nr r )�tokens�prev_row�prev_col�encoding)r+ r- r- r. �__init__� s zUntokenizer.__init__c C s� |\}}|| j k s&|| j kr>|| jk r>tdj||| j | j���|| j }|rb| jjd| � d| _|| j }|r�| jjd| � d S )Nz+start ({},{}) precedes previous end ({},{})z\ r � )r_ r` � ValueError�formatr^ �append)r+ �start�row�col� row_offset� col_offsetr- r- r. �add_whitespace� s zUntokenizer.add_whitespacec C s4 t |�}g }d}�x|D �] }t|�dkr8| j||� P |\}}}} } |tkrV|| _q|tkr`P |tkrv|j|� qnl|tkr�|j � | \| _ | _ qnL|t t fkr�d}n:|r�|r�|d } |d t| �kr�| jj| � t| �| _ d}| j|� | jj|� | \| _ | _ |t t fkr| j d7 _ d| _ qW dj| j�S )NFr Tr r rD ���)�iter�len�compatr ra � ENDMARKER�INDENTrf �DEDENT�popr_ r` �NEWLINEr r^ rl r8 ) r+ �iterable�it�indents� startlinerQ �tok_type�tokenrg �end�line�indentr- r- r. r � sF zUntokenizer.untokenizec C s� g }| j j}|d ttfk}d}x�t|g|�D ]�}|d d� \}} |tkrR| | _q.|ttt t fkrj| d7 } |t kr�|r~d| } d}nd}|t kr�|j| � q.n>|t kr�|j� q.n*|ttfkr�d}n|r�|r�||d � d}|| � q.W d S )Nr Fr rc Tr rm )r^ rf ru r r r ra �NAME�NUMBER�ASYNC�AWAIT�STRINGrr rs rt ) r+ r{ rv rx � toks_appendry � prevstring�tok�toknum�tokvalr- r- r. rp s8 zUntokenizer.compatN)r4 r5 r6 rb rl r rp r- r- r- r. r] � s %r] c C s* t � }|j| �}|jdk r&|j|j�}|S )a Transform tokens back into Python source code.

It requires one argument, readline, in the same way as the tokenize() generator. It will call readline a maximum of twice, and return the encoding used (as a string) and a list of any lines (left as bytes) it has read in. It detects the encoding from the presence of a utf-8 bom or an encoding cookie as specified in pep-0263. If both a bom and a cookie are present, but disagree, a SyntaxError will be raised. If the encoding cookie is an invalid charset, raise a SyntaxError. Note that if a utf-8 bom is found, 'utf-8-sig' is returned. If no encoding is specified, then the default of 'utf-8' will be returned.

Each call to the function should return one line of input as bytes. Alternatively, readline can be a callable function terminating with StopIteration: readline = open(myfile, 'rb').__next__ # Example of alternate readline The generator produces 5-tuples with these members: the token type; the token string; a 2-tuple (srow, scol) of ints specifying the row and column where the token begins in the source; a 2-tuple (erow, ecol) of ints specifying the row and column where the token ends in the source; and the line on which the token was found. The line passed is the logical line; continuation lines are included. The first token sequence will always be an ENCODING token which tells you which encoding was used to decode the bytes stream. r )r �repeatr� )� itertoolsr r� r rn � _tokenize�__next__)r� r r� ra �consumed�rl_gen�emptyr- r- r. r � s c ! c s" d } }}d}d!\}}d }dg} d } d} d} d} |d k rX|dkrFd}t t|d"d#d�V d}d}�x y|}| � }W n tk r� d}Y nX |d k r�|j|�}|d7 }dt|� }}|�r�|s�td |��|j|�}|�r|jd� }}t t||d |� |||f|| �V d$\}}d }nf|�rn|d%d � d k�rn|d&d � d k�rnt t || ||t|�f|�V d}d }qdn|| }|| }qd�n@|dk�r�| �r�|�s�P d}xf||k �r|| dk�r�|d7 }n6|| dk�r�|t d t }n|| dk�r�d}nP |d7 }�q�W ||k�rP || dk�r�|| dk�r�||d � j d�}|t|� }t t |||f||t|� f|�V t t ||d � ||f|t|�f|�V qdt t t f|| dk ||d � ||f|t|�f|�V qd|| d' k�r | j|� t t|d |� |df||f|�V xv|| d( k �r�|| k�r8tdd|||f��| d d)� } | �rd| | d* k�rdd} d} d} t td||f||f|�V �qW | �r�| �r�| | d+ k�r�d} d} d} n|�s�td|df��d}�x�||k �rztt�j||�}|�rL|jd�\}}||f||f| }} }||k�r �q�|||� || } } | |k�sZ| dk�rp| dk�rp| dk�rpt t| || |�V �qv| dk�r�| �r�| V d } |dk�r�t t | || |�V n t t| || |�V | �rJd} �qv| dk�r | jd� �s�t�| �r�| V d } t t | || |�V �qv| tk�r~tt| �}|j||�}|�r`|jd�}|||� } t t| |||f|�V n||f}||d � }|}P �qv| tk�s�| d d � tk�s�| d d � tk�r | d, dk�r ||f}ttj | ��p�tj | d ��p�tj | d ��}||d � d }}|}P nt t| || |�V �qv| j � �r�| d-k�r^| �r^t | dk�rJt nt | || |�V �q�t t | || |�} | dk�r�| �r�| } �q�| d k�r�| �r�| j!t k�r�| j"dk�r�d} | d. } t t | j"| j#| j| j$�V d } | �r�| V d } | V nX| d k�rd}nH| d k�r|d7 }n| d k�r(|d8 }| �r8| V d } t t%| || |�V n*t t || ||f||d f|�V |d7 }�q�W qdW | �r�| V d } |�r�|d/ dk�r�t td|d t|�f|d t|�d fd�V x0| dd � D ] } t td|df|dfd�V �q�W t t&d|df|dfd�V d S )0Nr � 0123456789rD Fz utf-8-sigzutf-8r� r zEOF in multi-line stringr z\ r z\ rc � � z# �#z z3unindent does not match any outer indentation levelz <tokenize>zEOF in multi-line statementr! z...T� �async�await�def�\z([{z)]})rD r )r r )r r )rD r ������rm rm rm rm rm rm )r� r� rm rm )'r r r� r� ro r[ r� r| r� � ERRORTOKEN�tabsize�rstripr r rf rr �IndentationErrorrs rW � PseudoToken�spanr� ru �endswith�AssertionError� triple_quoted�endpats� single_quoted�get� isidentifierr� r� r r( r1 rg r} r0 rq )!r� ra �lnum�parenlev� continued�numchars�contstr�needcont�contlinerx �stashed� async_def�async_def_indent� async_def_nl� last_liner} �pos�max�strstart�endprog�endmatchr| �column� comment_token�nl_pos� pseudomatchrg �spos�eposr{ �initialr� r~ r- r- r. r� � st * " . r� c C s t | d �S )N)r� )r� r- r- r. �generate_tokens� s r� c s( dd l } dd� � d� fdd� }| jdd�}|jdd d d d � |jd ddddd� |j� }y�|jr�|j}t|d��}tt|j��}W d Q R X nd}t t j jd �}xF|D ]>}|j }|j r�|j}d|j|j } td| t| |jf � q�W W �n8 tk �r: } z2| jd dd� \} } || jd || | f� W Y d d } ~ X n� tk �r� } z*| jd \} } || jd || | f� W Y d d } ~ X n� tk �r� } z|| |� W Y d d } ~ X nx tk �r� } z|| � W Y d d } ~ X nN tk �r� td� Y n2 tk �r" } z� d| � � W Y d d } ~ X nX d S ) Nr c S s t | tjd� d S )N)�file)�print�sys�stderr)�messager- r- r. �perror� s zmain.<locals>.perrorc sR |r"|f| | f }� d| � n"|r8� d|| f � n � d| � t jd� d S )Nz%s:%d:%d: error: %sz %s: error: %sz error: %sr )r� �exit)r� r� �location�args)r� r- r. �error� s zmain.<locals>.errorzpython -m tokenize)�progr� r< z filename.pyz'the file to tokenize; defaults to stdin)�dest�nargs�metavar�helpz-ez--exact�exact� store_truez(display token names using the exact type)r� �actionr r� z<stdin>z %d,%d-%d,%d:z%-20s%-15s%-15rr r z interrupted zunexpected error: %s)NN)�argparse�ArgumentParser� add_argument� parse_argsr� r� �listr r� r� r� �stdinr( r r3 rg r| r� r) r1 r� r� r[ r� �OSError�KeyboardInterrupt� Exception) r r� �parserr� r� rA r^ r{ � token_type� token_range�errr} r� r- )r� r. �main� sN && r �__main__)��__doc__� __author__� __credits__�builtinsr r� �codecsr r � collections�ior r� r rJ rS r� r{ rT �ASCIIr� r� �__all__�N_TOKENSr r) r r �LPAR�RPAR�LSQB�RSQB�COLON�COMMA�SEMI�PLUS�MINUS�STAR�SLASH�VBAR�AMPER�LESS�GREATER�EQUAL�DOT�PERCENT�LBRACE�RBRACE�EQEQUAL�NOTEQUAL� LESSEQUAL� GREATEREQUAL�TILDE� CIRCUMFLEX� LEFTSHIFT� RIGHTSHIFT� DOUBLESTAR� PLUSEQUAL�MINEQUAL� STAREQUAL� SLASHEQUAL� PERCENTEQUAL� AMPEREQUAL� VBAREQUAL�CIRCUMFLEXEQUAL�LEFTSHIFTEQUAL�RIGHTSHIFTEQUAL�DOUBLESTAREQUAL� DOUBLESLASH�DOUBLESLASHEQUAL�AT�ATEQUALr2 � namedtupler r: r; r= � Whitespace�Comment�Ignore�Name� Hexnumber� Binnumber� Octnumber� Decnumber� Intnumber�Exponent� Pointfloat�Expfloat� Floatnumber� Imagnumber�NumberrR rW � StringPrefix�Single�Double�Single3�Double3�Triple�String�Operator�Bracket�Special�Funny� PlainToken�Token�ContStr� PseudoExtrasr� r� �_prefixrI r� r� rQ r@ rM r� r r[ r\ r] r r� r r r� r� r r4 r- r- r- r. �<module> s _ ] x< xdrlib.cpython-36.pyc 0000644 00000020160 15246273046 0010466 0 ustar 00 3 \ � @ sx d Z ddlZddlmZ ddlmZ ddddgZG d d� de�ZG d d� de�Z d d � Z G d d� d�Z G dd� d�Z dS )zRImplements (a subset of) Sun XDR -- eXternal Data Representation.

Each string ends in a newline; the strings may contain internal newlines as well, for those items with source text lines. For long sequences of the same frame and line, the first few repetitions are shown, followed by a summary line stating the exact number of further repetitions.

The traceback module captures enough attributes from the original exception to this intermediary form to ensure that no references are held, while still being able to fully print or format it. Use `from_exception` to create TracebackException instances from exception objects, or the constructor to create TracebackException instances from individual components. - :attr:`__cause__` A TracebackException of the original *__cause__*. - :attr:`__context__` A TracebackException of the original *__context__*. - :attr:`__suppress_context__` The *__suppress_context__* value from the original exception. - :attr:`stack` A `StackSummary` representing the traceback. - :attr:`exc_type` The class of the original traceback. - :attr:`filename` For syntax errors - the filename where the error occurred. - :attr:`lineno` For syntax errors - the linenumber where the error occurred. - :attr:`text` For syntax errors - the text where the error occurred. - :attr:`offset` For syntax errors - the offset into the text where the error occurred. - :attr:`msg` For syntax errors - the compiler error message.

The return value is a generator of strings, each ending in a newline. Normally, the generator emits a single string; however, for SyntaxError exceptions, it emites several lines that (when printed) display detailed information about where the syntax error occurred. The message indicating which exception occurred is always the last string in the output.

The destination directory must not already exist. If exception(s) occur, an Error is raised with a list of reasons. If the optional symlinks flag is true, symbolic links in the source tree result in symbolic links in the destination tree; if it is false, the contents of the files pointed to by symbolic links are copied. If the file pointed by the symlink doesn't exist, an exception will be added in the list of errors raised in an Error exception at the end of the copy process. You can set the optional ignore_dangling_symlinks flag to true if you want to silence this exception. Notice that this has no effect on platforms that don't support os.symlink. The optional ignore argument is a callable. If given, it is called with the `src` parameter, which is the directory being visited by copytree(), and `names` which is the list of `src` contents, as returned by os.listdir(): callable(src, names) -> ignored_names Since copytree() is called recursively, the callable will be called once for each directory that is copied. It returns a list of names relative to the `src` directory that should not be copied. The optional copy_function argument is a callable that will be used to copy each file. It will be called with the source path and the destination path as arguments. By default, copy2() is used, but any function that supports the same signature (like copy()) can be used.

If ignore_errors is set, errors are ignored; otherwise, if onerror is set, it is called to handle the error with arguments (func, path, exc_info) where func is platform and implementation dependent; path is the argument to that function that caused it to fail; and exc_info is a tuple returned by sys.exc_info().

This is similar to the Unix "mv" command. Return the file or directory's destination. If the destination is a directory or a symlink to a directory, the source is moved inside the directory. The destination path must not already exist. If the destination already exists but is not a directory, it may be overwritten depending on os.rename() semantics. If the destination is on our current filesystem, then rename() is used. Otherwise, src is copied to the destination and then removed. Symlinks are recreated under the new name if os.rename() fails because of cross filesystem renames. The optional `copy_function` argument is a callable that will be used to copy the source or it will be delegated to `copytree`.

For each of the two dimensions, the environment variable, COLUMNS and LINES respectively, is checked. If the variable is defined and the value is a positive integer, it is used. When COLUMNS or LINES is not defined, which is the common case, the terminal connected to sys.__stdout__ is queried by invoking os.get_terminal_size. If the terminal size cannot be successfully queried, either because the system doesn't support querying, or because we are not connected to a terminal, the value given in fallback parameter is used. Fallback defaults to (80, 24) which is the default size used by many terminal emulators. The value returned is a named tuple of type os.terminal_size.

Each such tuple corresponds to a stack frame that is currently active (self.cur[-2]). The following are the definitions of its members. We use this external "parallel stack" to avoid contaminating the program that we are profiling. (old profiler used to write into the frames local dictionary!!) Derived classes can change the definition of some entries, as long as they leave [-2:] intact (frame and previous tuple). In case an internal error is detected, the -3 element is used as the function name. [ 0] = Time that needs to be charged to the parent frame's function. It is used so that a function call will not have to access the timing data for the parent frame. [ 1] = Total time spent in this frame's function, excluding time in subfunctions (this latter is tallied in cur[2]). [ 2] = Total time spent in subfunctions, excluding time executing the frame's function (this latter is tallied in cur[1]). [-3] = Name of the function that corresponds to this frame. [-2] = Actual frame that we correspond to (used to sync exception handling). [-1] = Our parent 6-tuple (corresponds to frame.f_back). Timing data for each function is stored as a 5-tuple in the dictionary self.timings[]. The index is always the name stored in self.cur[-3]. The following are the definitions of the members: [0] = The number of times this function was called, not counting direct or indirect recursion, [1] = Number of times this function appears on the stack, minus one [2] = Total time spent internal to this function [3] = Cumulative time that this function was present on the stack. In non-recursive functions, this is the total execution time from start to finish of each invocation of a function, including time spent in all subfunctions. [4] = A dictionary indicating for each function name, the number of times it was called by us. r Nc C s� i | _ d | _d| _d| _|d kr&| j}|| _|sHtj | _| _| j | _ nl|| _| j� }y t |�}W n" t k r� || _| j | _ Y n0X |dkr�| j | _ n| j| _ |tfdd�}|| _| j� | _| jd� d S )N� � c S s || � �S )Nr )�timer�sumr r r �get_time_timer� s z(Profile.__init__.<locals>.get_time_timerr )�timings�cur�cmd� c_func_name�bias�timeZ process_timer �get_time�trace_dispatch_i� dispatcher�len� TypeError�trace_dispatch�trace_dispatch_lr �t� simulate_call)r r r$ r- Zlengthr r r r r � s0 zProfile.__init__c C s� | j }|� }|d |d | j | j }|dkr8|j| _| j| | ||�rd|� }|d |d | _n |� }|d |d | | _d S )Nr r �c_call)r r- r$ r r# �dispatch)r �frame�event�argr r- �rr r r r+ � s zProfile.trace_dispatchc C sT | j }|� | j | j }|dkr(|j| _| j| | ||�rD|� | _n |� | | _d S )Nr/ )r r- r$ r r# r0 )r r1 r2 r3 r r- r r r r' � s zProfile.trace_dispatch_ic C s` | j }|� d | j | j }|dkr,|j| _| j| | ||�rL|� d | _n|� d | | _d S )Ng N@r/ )r r- r$ r r# r0 )r r1 r2 r3 r r- r r r �trace_dispatch_mac� s zProfile.trace_dispatch_macc C sT | j }|� | j | j }|dkr(|j| _| j| | ||�rD|� | _n |� | | _d S )Nr/ )r& r- r$ r r# r0 )r r1 r2 r3 r& r- r r r r, � s zProfile.trace_dispatch_lc C sD | j \}}}}}}||k r*|r*| j||�S ||| ||||f| _ dS )Nr )r! �trace_dispatch_return) r r1 r- �rpt�rit�ret�rfn�rframe�rcurr r r �trace_dispatch_exception� s z Profile.trace_dispatch_exceptionc C s | j r�|j| j d k r�| j \}}}}}}t|tj�s�|j|jksXtd|||j||jf��| j|d� | j d ks�|j| j d ks�td| j d f��|j} | j| j | j f} |dd| || j f| _ | j } | | kr�| | \} } }}}| | d |||f| | < nddddi f| | < dS ) Nr zBad callr � r ���r?

The completer completes keywords, built-ins and globals in a selectable namespace (which defaults to __main__); when completing NAME.NAME..., it evaluates (!) the expression up to the last dot and completes its attributes. It's very cool to do "import sys" type "sys.", hit the completion key (twice), and see the list of names defined by the sys module! Tip: to use the tab key as the completion key, call readline.parse_and_bind("tab: complete") Notes: - Exceptions raised by the completer function are *ignored* (and generally cause the completion to fail). This is a feature -- since readline sets the tty device in raw (or cbreak) mode, printing a traceback wouldn't work well without some complicated hoopla to save, reset and restore the tty state. - The evaluation of the NAME.NAME... form may cause arbitrary application defined code to be executed if an object with a __getattr__ hook is found. Since it is the responsibility of the application (or the user) to enable this feature, I consider this an acceptable risk. More complicated expressions (e.g. function calls or indexing operations) are *not* evaluated. - When the original stdin is not a tty device, GNU readline is never used, and this module (and the readline module) are silently inactive. � N� Completerc @ s6 e Zd Zd dd�Zdd� Zdd� Zdd � Zd d � ZdS ) r Nc C s8 |rt |t� rtd��|dkr(d| _n d| _|| _dS )a� Create a new completer for the command line.

Function whathdr() recognizes various types of sound file headers. It understands almost all headers that SOX can decode. The return tuple contains the following items, in this order: - file type (as SOX understands it) - sampling rate (0 if unknown or hard to decode) - number of channels (0 if unknown or hard to decode) - number of frames in the file (-1 if unknown or hard to decode) - number of bits/sample, or 'U' for U-LAW, or 'A' for A-LAW If the file doesn't have a recognizable type, it returns None. If the file can't be opened, OSError is raised. To compute the total time, divide the number of frames by the sampling rate (a frame contains a sample for each channel). Function what() calls whathdr(). (It used to also use some heuristics for raw data, but this doesn't work very well.) Finally, the function test() is a simple main program that calls what() for all files mentioned on the argument list. For directory arguments it calls what() for all files in that directory. Default argument is "." (testing all files in the current directory). The option -r tells it to recurse down directories found inside explicitly given directories. �what�whathdr� )� namedtuple� SndHeadersz.filetype framerate nchannels nframes sampwidthz�The value for type indicates the data type and will be one of the strings 'aifc', 'aiff', 'au','hcom', 'sndr', 'sndt', 'voc', 'wav', '8svx', 'sb', 'ub', or 'ul'.zYThe sampling_rate will be either the actual value or 0 if unknown or difficult to decode.z^The number of channels or 0 if it cannot be determined or if the value is difficult to decode.z?The value for frames will be either the number of frames or -1.zAEither the sample size in bits or 'A' for A-LAW or 'U' for u-LAW.c C s t | �}|S )z Guess the type of a sound file.)r )�filename�res� r � /usr/lib64/python3.6/sndhdr.pyr 4 s c C sH t | d��4}|jd�}x"tD ]}|||�}|r t|� S q W dS Q R X dS )zRecognize sound headers.�rbi N)�open�read�testsr )r �f�hZtfr r r r r : s c C s� dd l }| jd�sd S | dd� dkr,d}n| dd� dkrBd}nd S |jd� y|j|d �}W n t|jfk rz d S X ||j� |j� |j� d|j � fS ) Nr s FORM� � s AIFC�aifcs AIFFZaiff�r) r � startswith�seekr �EOFError�Error� getframerate� getnchannels� getnframes� getsampwidth)r r r Zfmt�ar r r � test_aifcK s r c C s� | j d�rt}n| d d� dkr&t}nd S d}|| dd� �}|| dd� �}|| dd� �}|| dd � �}|| d d � �}d } |d kr�d } n$|d kr�d} n|dkr�d} d } nd} | | } | r�|| } nd} |||| | fS )Ns .snd� � ds.� dns.Zaur r � � � � �U� � �?)r r ���)r � get_long_be� get_long_le) r r �func�filetypeZhdr_sizeZ data_size�encoding�rate� nchannelsZ sample_sizeZ sample_bitsZ frame_sizeZnframer r r �test_au` s2 r1 c C sT | dd� dks | dd� dkr$d S t | dd� �}|rBd | }nd }d |d dd fS )N�A �E s FSSD� � s HCOM� � i"V r Zhcomr$ r r) )r* )r r Zdivisorr/ r r r � test_hcom� s r8 c C st | j d�sd S t| dd� �}d}d| ko4dk n rf| | dkrfd| |d }|rftd | �}d |dd d fS ) Ns Creative Voice Filer" � r i� r$ � r g ��.AZvocr r) )r � get_short_le�int)r r Zsbseekr/ Zratecoder r r �test_voc� s $ r= c C s� dd l }| jd� s4| dd� dks4| dd� dkr8d S |jd� y|j|d�}W n t|jfk rl d S X d |j� |j� |j� d|j � fS ) Nr s RIFFr r s WAVEr!

'surrogateescape' - replace with private code points U+DCnn. 'xmlcharrefreplace' - Replace with the appropriate XML character reference (only for encoding). 'backslashreplace' - Replace with backslashed escape sequences. 'namereplace' - Replace with \N{...} escape sequences (only for encoding).

The decoder can modify this setting as appropriate. The default value -1 indicates to read and decode as much as possible. size is intended to prevent having to decode huge files in one step. If firstline is true, and a UnicodeDecodeError happens after the first line terminator in the input only the first line will be returned, the rest of the input will be kept until the next call to read(). The method should use a greedy read strategy, meaning that it should read as much data as is allowed within the definition of the encoding and the given size, e.g. if optional encoding endings or state markers are available on the stream, these should be read too.

They use the complete set of APIs returned by the codecs.lookup() function to implement their task. Data written to the StreamRecoder is first decoded into an intermediate format (depending on the "decode" codec) and then written to the underlying stream using an instance of the provided Writer class. In the other direction, data is read from the underlying stream using a Reader instance and then encoded and returned to the caller. r� rC c C s4 || _ || _|| _|||�| _|||�| _|| _dS )a� Creates a StreamRecoder instance which implements a two-way conversion: encode and decode work on the frontend (the data visible to .read() and .write()) while Reader and Writer work on the backend (the data in stream). You can use these objects to do transparent transcodings from e.g. latin-1 to utf-8 and back. stream must be a file-like object. encode and decode must adhere to the Codec interface; Reader and Writer must be factory functions or classes providing the StreamReader and StreamWriter interfaces resp. Error handling is done in the same way as defined for the StreamWriter/Readers.

Note: The wrapped version will only accept the object format defined by the codecs, i.e. Unicode objects for most builtin codecs. Output is also codec dependent and will usually be Unicode as well. Underlying encoded files are always opened in binary mode. The default file mode is 'r', meaning to open the file in read mode. encoding specifies the encoding which is to be used for the file. errors may be given to define the error handling. It defaults to 'strict' which causes ValueErrors to be raised in case an encoding error occurs. buffering has the same meaning as for the builtin open() API. It defaults to line buffered. The returned wrapped file object provides an extra attribute .encoding which allows querying the used encoding. This attribute is only available if an encoding was specified as parameter.

Data written to the wrapped file is decoded according to the given data_encoding and then encoded to the underlying file using file_encoding. The intermediate data type will usually be Unicode but depends on the specified codecs. Bytes read from the file are decoded using file_encoding and then passed back to the caller encoded using data_encoding. If file_encoding is not given, it defaults to data_encoding. errors may be given to define the error handling. It defaults to 'strict' which causes ValueErrors to be raised in case an encoding error occurs. The returned wrapped file object provides two extra attributes .data_encoding and .file_encoding which reflect the given parameters of the same name. The attributes can be used for introspection by Python programs.

Usage. Reading WAVE files: f = wave.open(file, 'r') where file is either the name of a file or an open file pointer. The open file pointer must have methods read(), seek(), and close(). When the setpos() and rewind() methods are not used, the seek() method is not necessary. This returns an instance of a class with the following public methods: getnchannels() -- returns number of audio channels (1 for mono, 2 for stereo) getsampwidth() -- returns sample width in bytes getframerate() -- returns sampling frequency getnframes() -- returns number of audio frames getcomptype() -- returns compression type ('NONE' for linear samples) getcompname() -- returns human-readable version of compression type ('not compressed' linear samples) getparams() -- returns a namedtuple consisting of all of the above in the above order getmarkers() -- returns None (for compatibility with the aifc module) getmark(id) -- raises an error since the mark does not exist (for compatibility with the aifc module) readframes(n) -- returns at most n frames of audio rewind() -- rewind to the beginning of the audio stream setpos(pos) -- seek to the specified position tell() -- return the current position close() -- close the instance (make it unusable) The position returned by tell() and the position given to setpos() are compatible and have nothing to do with the actual position in the file. The close() method is called automatically when the class instance is destroyed. Writing WAVE files: f = wave.open(file, 'w') where file is either the name of a file or an open file pointer. The open file pointer must have methods write(), tell(), seek(), and close(). This returns an instance of a class with the following public methods: setnchannels(n) -- set the number of channels setsampwidth(n) -- set the sample width setframerate(n) -- set the frame rate setnframes(n) -- set the number of frames setcomptype(type, name) -- set the compression type and the human-readable compression type setparams(tuple) -- set all parameters at once tell() -- return current position in output file writeframesraw(data) -- write audio frames without pathing up the file header writeframes(data) -- write audio frames and patch up the file header close() -- patch up the file header and close the output file You should set the parameters before the first writeframesraw or writeframes. The total number of frames does not need to be set, but when it is set to the correct value, the header does not have to be patched up. It is best to first set all parameters, perhaps possibly the compression type, and then write audio frames using writeframesraw. When all frames have been written, either call writeframes(b'') or close() to patch up the sizes in the header. The close() method is called automatically when the class instance is destroyed. � N�open�openfp�Error� Wave_read� Wave_writec @ s e Zd ZdS )r N)�__name__� __module__� __qualname__� r r � /usr/lib64/python3.6/wave.pyr N s � �b�h�i)�Chunk)� namedtuple� _wave_paramsz7nchannels sampwidth framerate nframes comptype compnamec @ s� e Zd ZdZdd� Zdd� Zdd� Zdd � Zd d � Zd d � Z dd� Z dd� Z dd� Z dd� Z dd� Zdd� Zdd� Zd d � Zd d � Zd d!� Zd"d#� Zd$d%� Zd&d'� Zd(d)� Zd*d+� Zd,S )-r aP Variables used in this class: These variables are available to the user though appropriate methods of this class: _file -- the open file with methods read(), close(), and seek() set through the __init__() method _nchannels -- the number of audio channels available through the getnchannels() method _nframes -- the number of audio frames available through the getnframes() method _sampwidth -- the number of bytes per audio sample available through the getsampwidth() method _framerate -- the sampling frequency available through the getframerate() method _comptype -- the AIFF-C compression type ('NONE' if AIFF) available through the getcomptype() method _compname -- the human-readable AIFF-C compression type available through the getcomptype() method _soundpos -- the position in the audio stream available through the tell() method, set through the setpos() method These variables are used internally only: _fmt_chunk_read -- 1 iff the FMT chunk has been read _data_seek_needed -- 1 iff positioned correctly in audio file for readframes() _data_chunk -- instantiation of a chunk class for the DATA chunk _framesize -- size of one frame in the file c C s d | _ d| _t|dd�| _| jj� dkr0td��| jjd�dkrHtd��d| _d | _x�d| _ yt| jdd�}W n t k r� P Y nX |j� }|d kr�| j |� d| _n2|d kr�| js�td ��|| _|j | j | _d| _ P |j� qVW | j s�| j �r td ��d S ) Nr )Z bigendians RIFFz file does not start with RIFF id� s WAVEznot a WAVE filer s fmt s datazdata chunk before fmt chunkz#fmt chunk and/or data chunk missing)�_convert� _soundposr �_fileZgetnamer �readZ_fmt_chunk_read� _data_chunk�_data_seek_needed�EOFError�_read_fmt_chunkZ chunksize� _framesize�_nframes�skip)�self�file�chunkZ chunknamer r r �initfp} s: zWave_read.initfpc C sR d | _ t|t�r"tj|d�}|| _ y| j|� W n | j rF|j� � Y nX d S )N�rb)�_i_opened_the_file� isinstance�str�builtinsr r" �close)r �fr r r �__init__� s zWave_read.__init__c C s | j � d S )N)r( )r r r r �__del__� s zWave_read.__del__c C s | S )Nr )r r r r � __enter__� s zWave_read.__enter__c G s | j � d S )N)r( )r �argsr r r �__exit__� s zWave_read.__exit__c C s | j S )N)r )r r r r �getfp� s zWave_read.getfpc C s d| _ d| _d S )Nr r )r r )r r r r �rewind� s zWave_read.rewindc C s" d | _ | j}|r d | _|j� d S )N)r r$ r( )r r r r r r( � s zWave_read.closec C s | j S )N)r )r r r r �tell� s zWave_read.tellc C s | j S )N)� _nchannels)r r r r � getnchannels� s zWave_read.getnchannelsc C s | j S )N)r )r r r r � getnframes� s zWave_read.getnframesc C s | j S )N)� _sampwidth)r r r r � getsampwidth� s zWave_read.getsampwidthc C s | j S )N)� _framerate)r r r r � getframerate� s zWave_read.getframeratec C s | j S )N)� _comptype)r r r r � getcomptype� s zWave_read.getcomptypec C s | j S )N)� _compname)r r r r � getcompname� s zWave_read.getcompnamec C s* t | j� | j� | j� | j� | j� | j� �S )N)r r3 r6 r8 r4 r: r< )r r r r � getparams� s zWave_read.getparamsc C s d S )Nr )r r r r � getmarkers� s zWave_read.getmarkersc C s t d��d S )Nzno marks)r )r �idr r r �getmark� s zWave_read.getmarkc C s* |dk s|| j krtd��|| _d| _d S )Nr zposition not in ranger )r r r r )r �posr r r �setpos� s zWave_read.setposc C s� | j r8| jjdd� | j| j }|r2| jj|d� d| _ |dkrDdS | jj|| j �}| jdkrxtjdkrxt j || j�}| j r�|r�| j |�}| jt |�| j | j | _|S )Nr � r �big)r r �seekr r r r5 �sys� byteorder�audioop�byteswapr �lenr2 )r �nframesrA �datar r r � readframes� s zWave_read.readframesc C sz t jd|jd��\}| _| _}}|tkrNt jd|jd��d }|d d | _ntd|f ��| j| j | _d | _ d | _ d S ) Nz<HHLLH� z<H� r � � zunknown format: %r�NONEznot compressed) �structZ unpack_fromr r2 r7 �WAVE_FORMAT_PCMr5 r r r9 r; )r r!

The builtin open function is defined in this module. At the top of the I/O hierarchy is the abstract base class IOBase. It defines the basic interface to a stream. Note, however, that there is no separation between reading and writing to streams; implementations are allowed to raise an OSError if they do not support a given operation. Extending IOBase is RawIOBase which deals simply with the reading and writing of raw bytes to a stream. FileIO subclasses RawIOBase to provide an interface to OS files. BufferedIOBase deals with buffering on a raw byte stream (RawIOBase). Its subclasses, BufferedWriter, BufferedReader, and BufferedRWPair buffer streams that are readable, writable, and both respectively. BufferedRandom provides a buffered interface to random access streams. BytesIO is a simple stream of in-memory bytes. Another IOBase subclass, TextIOBase, deals with the encoding and decoding of streams into text. TextIOWrapper, which extends it, is a buffered text interface to a buffered raw stream (`BufferedIOBase`). Finally, StringIO is an in-memory stream for text. Argument names are not part of the specification, and only the arguments of open() are intended to be used as keyword arguments. data: DEFAULT_BUFFER_SIZE An int containing the default buffer size used by the module's buffered I/O classes. open() uses the file's blksize (as obtained by os.stat) if possible. z�Guido van Rossum <guido@python.org>, Mike Verdone <mike.verdone@gmail.com>, Mark Russell <mark.russell@zen.co.uk>, Antoine Pitrou <solipsis@pitrou.net>, Amaury Forgeot d'Arc <amauryfa@gmail.com>, Benjamin Peterson <benjamin@python.org>�BlockingIOError�open�IOBase� RawIOBase�FileIO�BytesIO�StringIO�BufferedIOBase�BufferedReader�BufferedWriter�BufferedRWPair�BufferedRandom� TextIOBase� TextIOWrapper�UnsupportedOperation�SEEK_SET�SEEK_CUR�SEEK_END� N) �DEFAULT_BUFFER_SIZEr r r r r r r r r r �IncrementalNewlineDecoderr �io� � c @ s e Zd ZejjZdS )r N)�__name__� __module__� __qualname__�_io�_IOBase�__doc__� r r �/usr/lib64/python3.6/io.pyr H s )� metaclassc @ s e Zd ZejjZdS )r N)r r r r � _RawIOBaser r r r r r K s c @ s e Zd ZejjZdS )r N)r r r r �_BufferedIOBaser r r r r r N s c @ s e Zd ZejjZdS )r N)r r r r � _TextIOBaser r r r r r Q s )�_WindowsConsoleIO)$r � __author__�__all__r �abcr r r r r r r r r r r r r � OpenWrapperr r r r r �ABCMetar r" r r# r r$ r �register�klassr% � ImportErrorr r r r �<module>" s< < imghdr.cpython-36.opt-1.pyc 0000644 00000010070 15246273046 0011412 0 ustar 00 3 \� � @ s2 d Z ddlmZ dgZd%dd�Zg Zdd� Zeje� dd � Zeje� d d � Z eje � d d � Z eje � dd� Z eje � dd� Z eje � dd� Z eje � dd� Zeje� dd� Zeje� dd� Zeje� dd� Zeje� d d � Zeje� d d � Zeje� d d!� Zd"d#� Zed$k�r.e� dS )&z<Recognize image file formats based on their first few bytes.� )�PathLike�whatNc C s� d }zl|d krNt | ttf�r2t| d�}|jd�}n | j� }| jd�}| j|� x tD ]}|||�}|rT|S qTW W d |r~|j� X d S )N�rb� ) � isinstance�strr �open�read�tell�seek�tests�close)�file�h�f�locationZtf�res� r � /usr/lib64/python3.6/imghdr.pyr s c C s | dd� dkrdS dS )z JPEG data in JFIF or Exif format� � � JFIF� ExifZjpegN)r r r )r r r r r � test_jpeg% s r c C s | j d�rdS d S )Ns �PNG Zpng)� startswith)r r r r r �test_png, s r c C s | dd� dkrdS dS )zGIF ('87 and '89 variants)Nr � GIF87a� GIF89aZgif)r r r )r r r r r �test_gif2 s r c C s | dd� dkrdS dS )z-TIFF (can be in Motorola or Intel byte order)N� � MM� IIZtiff)r r! r )r r r r r � test_tiff9 s r" c C s | j d�rdS dS )zSGI image librarys �ZrgbN)r )r r r r r �test_rgb@ s r# c C s< t | �dkr8| d td�kr8| d dkr8| d dkr8dS d S ) zPBM (portable bitmap)� r � P� s 14r s ZpbmN)�len�ord)r r r r r �test_pbmG s (r) c C s< t | �dkr8| d td�kr8| d dkr8| d dkr8dS d S ) zPGM (portable graymap)r$ r r% r& s 25r s ZpgmN)r' r( )r r r r r �test_pgmO s (r* c C s< t | �dkr8| d td�kr8| d dkr8| d dkr8dS d S ) zPPM (portable pixmap)r$ r r% r& s 36r s ZppmN)r' r( )r r r r r �test_ppmW s (r+ c C s | j d�rdS dS )zSun raster files Y�j�ZrastN)r )r r r r r � test_rast_ s r, c C s | j d�rdS dS )zX bitmap (X10 or X11)s #define ZxbmN)r )r r r r r �test_xbmf s r- c C s | j d�rdS d S )Ns BMZbmp)r )r r r r r �test_bmpm s r. c C s" | j d�r | dd� dkr dS d S )Ns RIFF� � s WEBPZwebp)r )r r r r r � test_webps s r1 c C s | j d�rdS d S )Ns v/1Zexr)r )r r r r r �test_exry s r2 c C s� dd l } d}| jdd � r8| jd dkr8| jdd�= d}y8| jdd � r`t| jdd � |d� ntdg|d� W n* tk r� | jjd� | jd� Y nX d S )Nr r& z-rr �.z [Interrupted] )�sys�argv�testall�KeyboardInterrupt�stderr�write�exit)r4 � recursiver r r �test� s r< c C s� dd l }dd l}x�| D ]�}|jj|�rzt|d dd� |s>|rptd� dd l}|j|jj|d��}t||d� q�td� qt|d dd� |jj � ytt |�� W q t k r� td � Y qX qW d S ) Nr z/:� )�endzrecursing down:�*z*** directory (use -r) ***�:z*** not found ***) r4 �os�path�isdir�print�glob�joinr6 �stdout�flushr �OSError)�listr; Ztoplevelr4 rA �filenamerE �namesr r r r6 � s" r6 �__main__)N)�__doc__rA r �__all__r r r �appendr r r" r# r) r* r+ r, r- r. r1 r2 r< r6 �__name__r r r r �<module> sD hmac.cpython-36.opt-1.pyc 0000644 00000013577 15246273046 0011067 0 ustar 00 3 ��i� � @ s� d Z ddlZddlmZ ddlZddlZddl Z e dd� e d�D ��Z e dd� e d�D ��Z dZG dd � d �Zd d � ZG d d � d e j�Zej� r�eZddd�ZdS )zxHMAC (Keyed-Hashing for Message Authentication) Python module.

Arguments can be strings or integers (where appropriate) (e.g.: retr(1) and retr('1') both work equally well. Minimal Command Set: USER name user(name) PASS string pass_(string) STAT stat() LIST [msg] list(msg = None) RETR msg retr(msg) DELE msg dele(msg) NOOP noop() RSET rset() QUIT quit() Optional Commands (some servers support these): RPOP name rpop(name) APOP name digest apop(name, digest) TOP msg n top(msg, n) UIDL [msg] uidl(msg = None) CAPA capa() STLS stls() UTF8 utf8() Raises one exception: 'error_proto'. Instantiate with: POP3(hostname, port=110) NB: the POP protocol locks the mailbox from user authorization until QUIT, so be sure to get in, suck the messages, and quit, each time you access the mailbox. POP is a line-based protocol, which means large mail messages consume lots of python cycles reading them line-by-line. If it's available on your mail server, use IMAP4 instead, it doesn't suffer from the two problems above. zUTF-8c C s@ || _ || _d| _| j|�| _| jjd�| _d| _| j� | _ d S )NF�rbr ) �host�port�_tls_established�_create_socket�sock�makefile�file� _debugging�_getresp�welcome)�selfr r �timeoutr r r �__init__a s z POP3.__init__c C s t j| j| jf|�S )N)�socketZcreate_connectionr r )r r r r r r k s zPOP3._create_socketc C s, | j dkrtdt|�� | jj|t � d S )N� z*put*)r �print�reprr Zsendall�CRLF)r �liner r r �_putlinen s z POP3._putlinec C sB | j rtdt|�� t|| j�}tjd|�r4td��| j|� d S )Nz*cmd*s [ - ]z*Control characters not allowed in commands) r r r �bytes�encoding�re�search� ValueErrorr )r r r r r �_putcmdu s z POP3._putcmdc C s� | j jtd �}t|�tkr$td��| jdkr<tdt|�� |sHtd��t|�}|dd � tkrp|d d� |fS |d d� t kr�|dd� |fS |d d � |fS ) Nr z line too longz*get*z-ERR EOF� ���r( ���r) ) r �readline�_MAXLINE�lenr r r r r �CR)r r �octetsr r r �_getline� s z POP3._getlinec C s: | j � \}}| jdkr$tdt|�� |jd�s6t|��|S )Nr z*resp*� +)r/ r r r � startswithr )r �resp�or r r r � s z POP3._getrespc C sp | j � }g }d}| j� \}}xH|dkrd|jd�rD|d }|dd � }|| }|j|� | j� \}}q W |||fS )Nr � .s ..r )r r/ r1 �append)r r2 �listr. r r3 r r r � _getlongresp� s zPOP3._getlongrespc C s | j |� | j� S )N)r& r )r r r r r � _shortcmd� s zPOP3._shortcmdc C s | j |� | j� S )N)r& r7 )r r r r r �_longcmd� s z POP3._longcmdc C s | j S )N)r )r r r r � getwelcome� s zPOP3.getwelcomec C s || _ d S )N)r )r �levelr r r �set_debuglevel� s zPOP3.set_debuglevelc C s | j d| �S )zVSend user name, return response (should indicate password required). zUSER %s)r8 )r �userr r r r= � s z POP3.userc C s | j d| �S )z�Send password, return response (response includes message count, mailbox size).

A "shelf" is a persistent, dictionary-like object. The difference with dbm databases is that the values (not the keys!) in a shelf can be essentially arbitrary Python objects -- anything that the "pickle" module can handle. This includes most class instances, recursive data types, and objects containing lots of shared sub-objects. The keys are ordinary strings. To summarize the interface (key is a string, data is an arbitrary object): import shelve d = shelve.open(filename) # open, with (g)dbm filename -- no suffix d[key] = data # store data at key (overwrites old data if # using an existing key) data = d[key] # retrieve a COPY of the data at key (raise # KeyError if no such key) -- NOTE that this # access returns a *copy* of the entry! del d[key] # delete data stored at key (raises KeyError # if no such key) flag = key in d # true if the key exists list = d.keys() # a list of all existing keys (slow!) d.close() # close it Dependent on the implementation, closing a persistent dictionary may or may not be necessary to flush changes to disk. Normally, d[key] returns a COPY of the entry. This needs care when mutable entries are mutated: for example, if d[key] is a list, d[key].append(anitem) does NOT modify the entry d[key] itself, as stored in the persistent mapping -- it only modifies the copy, which is then immediately discarded, so that the append has NO effect whatsoever. To append an item to d[key] in a way that will affect the persistent mapping, use: data = d[key] data.append(anitem) d[key] = data To avoid the problem with mutable entries, you may pass the keyword argument writeback=True in the call to shelve.open. When you use: d = shelve.open(filename, writeback=True) then d keeps a cache of all entries you access, and writes them all back to the persistent mapping when you call d.close(). This ensures that such usage as d[key].append(anitem) works as intended. However, using keyword argument writeback=True may consume vast amount of memory for the cache, and it may make d.close() very slow, if you access many of d's entries after opening it in this way: d has no way to check which of the entries you access are mutable and/or which ones you actually mutate, so it must cache, and write back at close, all of the entries that you access. You can call d.sync() to write back all the entries in the cache, and empty the cache (d.sync() also synchronizes the persistent dictionary on disk, if feasible). � )�Pickler� Unpickler)�BytesION�Shelf� BsdDbShelf�DbfilenameShelf�openc @ s8 e Zd ZdZdd� Ze Z Z Z Z Z Z dd� Z dS )� _ClosedDictz>Marker for a closed dict.

The filename argument can be an actual filename (a str or bytes object), or an existing file object to read from or write to. The mode argument can be "r", "rb", "w", "wb", "x", "xb", "a" or "ab" for binary mode, or "rt", "wt", "xt" or "at" for text mode. The default mode is "rb", and the default compresslevel is 9. For binary mode, this function is equivalent to the GzipFile constructor: GzipFile(filename, mode, compresslevel). In this case, the encoding, errors and newline arguments must not be provided. For text mode, a GzipFile object is created, and wrapped in an io.TextIOWrapper instance with the specified encoding, error handling behavior, and line ending(s). �t�bzInvalid mode: %rNz0Argument 'encoding' not supported in binary modez.Argument 'errors' not supported in binary modez/Argument 'newline' not supported in binary mode� �read�writez1filename must be a str or bytes object, or a file) � ValueError�replace� isinstance�str�bytes�os�PathLiker �hasattr� TypeError�io� TextIOWrapper)�filename�mode� compresslevel�encoding�errors�newlineZgz_modeZ binary_file� r# � /usr/lib64/python3.6/gzip.pyr s$ c C s | j tjd|�� d S )Nz<L)r �structZpack)�output�valuer# r# r$ �write32u@ s r( c @ s< e Zd ZdZddd�Zdd� Zddd�Zd d � Zd d � Zd S )� _PaddedFilez�Minimal read-only file object that prepends a string to the contents of an actual file.

At least one of fileobj and filename must be given a non-trivial value. The new class instance is based on fileobj, which can be a regular file, an io.BytesIO object, or any other object which simulates a file. It defaults to None, in which case filename is opened to provide a file object. When fileobj is not None, the filename argument is only used to be included in the gzip file header, which may include the original filename of the uncompressed file. It defaults to the filename of fileobj, if discernible; otherwise, it defaults to the empty string, and in this case the original filename is not included in the header. The mode argument can be any of 'r', 'rb', 'a', 'ab', 'w', 'wb', 'x', or 'xb' depending on whether the file will be read or written. The default is the mode of fileobj if discernible; otherwise, the default is 'rb'. A mode of 'r' is equivalent to one of 'rb', and similarly for 'w' and 'wb', 'a' and 'ab', and 'x' and 'xb'. The compresslevel argument is an integer from 0 to 9 controlling the level of compression; 1 is fastest and produces the least compression, and 9 is slowest and produces the most compression. 0 is no compression at all. The default is 9. The mtime argument is an optional numeric timestamp to be written to the last modification time field in the stream when compressing. If omitted or None, the current time is used. r �UzInvalid mode: {!r}r Nr �namer r �r�w�a�xr )r> r? r@ ) r �format�builtinsr � myfileobj�getattrr r r r �fspath� startswith�READr � _GzipReaderr �BufferedReaderr+ r< �WRITE� _init_write�zlibZ compressobjZDEFLATED� MAX_WBITSZ DEF_MEM_LEVELr � _write_mtime�fileobj�_write_gzip_header)r0 r r r rO �mtime�rawr# r# r$ r3 { s> # zGzipFile.__init__c C sB dd l }|jdtd� | jtkr<| jdd � dkr<| jd S | jS )Nr zuse the name attributer � z.gz���)�warnings�warn�DeprecationWarningr rJ r< )r0 rU r# r# r$ r � s zGzipFile.filenamec C s | j jjS )z0Last modification time read from stream, or None)r+ rR � _last_mtime)r0 r# r# r$ rQ � s zGzipFile.mtimec C s. t | j�}d|dd� d tt| �� d S )Nz<gzip r � �>���)�reprrO �hex�id)r0 �sr# r# r$ �__repr__� s zGzipFile.__repr__c C s. || _ tjd�| _d| _g | _d| _d| _d S )Nr* r )r< rL �crc32�crcr4 Zwritebuf�bufsize�offset)r0 r r# r# r$ rK � s zGzipFile._init_writec C s� | j jd� | j jd� y<tjj| j�}t|t�s<|jd�}|j d�rR|d d � }W n t k rl d}Y nX d}|rzt }| j jt |�jd�� | j }|d kr�tj� }t| j t|�� | j jd� | j jd � |r�| j j|d � d S ) Ns �� zlatin-1s .gzrS r* r � � �� rT )rO r r �path�basenamer< r r �encode�endswith�UnicodeEncodeError�FNAME�chrrN �timer( �int)r0 Zfname�flagsrQ r# r# r$ rP � s, zGzipFile._write_gzip_headerc C s� | j � | jtkr&dd l}t|jd��| jd kr8td��t|t �rLt |�}nt |�}|j }|dkr�| jj | jj|�� | j|7 _tj|| j�| _| j|7 _|S )Nr z$write() on read-only GzipFile objectz!write() on closed GzipFile object)�_check_not_closedr rJ �errno�OSError�EBADFrO r r r r, � memoryview�nbytesr r r4 rL ra rb rd )r0 �datart Zlengthr# r# r$ r � s zGzipFile.writer c C s2 | j � | jtkr&dd l}t|jd��| jj|�S )Nr z$read() on write-only GzipFile object)rs r rG rt ru rv r+ r )r0 r4 rt r# r# r$ r s z GzipFile.readc C s@ | j � | jtkr&ddl}t|jd��|dk r4tj}| jj |�S )zdImplements BufferedIOBase.read1() Reads up to a buffer's worth of data is size is negative.r Nz%read1() on write-only GzipFile object) rs r rG rt ru rv r �DEFAULT_BUFFER_SIZEr+ �read1)r0 r4 rt r# r# r$ r{ s zGzipFile.read1c C s2 | j � | jtkr&dd l}t|jd��| jj|�S )Nr z$peek() on write-only GzipFile object)rs r rG rt ru rv r+ �peek)r0 �nrt r# r# r$ r| # s z GzipFile.peekc C s | j d kS )N)rO )r0 r# r# r$ �closed* s zGzipFile.closedc C s� | j }|d krd S d | _ zP| jtkrR|j| jj� � t|| j� t|| jd@ � n| jt krf| j j � W d | j }|r�d | _ |j � X d S )Nl �� ) rO r rJ r r �flushr( rb r4 rG r+ �closerC )r0 rO rC r# r# r$ r� . s zGzipFile.closec C s4 | j � | jtkr0| jj| jj|�� | jj� d S )N)rs r rJ rO r r r )r0 Z zlib_moder# r# r$ r A s zGzipFile.flushc C s | j j� S )z�Invoke the underlying file object's fileno() method.

This is a descriptor, used to define attributes that act differently when accessed through an instance and through a class. Instance access remains normal, but access to an attribute through a class will be routed to the class's __getattr__ method; this is done by raising AttributeError. This allows one to have properties active on an instance, and have virtual attributes on the class with the same name (see Enum for an example).

In the two-argument form of the constructor, Fraction(8, 6) will produce a rational number equivalent to 4/3. Both arguments must be Rational. The numerator defaults to 0 and the denominator defaults to 1 so that Fraction(3) == 3 and Fraction() == 0. Fractions can also be constructed from: - numeric strings similar to those accepted by the float constructor (for example, '-2.3' or '1e10') - strings of the form '123/456' - float and Decimal instances - other Rational instances (including integers) � _numerator� _denominatorr NT)� _normalizec sR t t| �j| �}|dk�rdt|�tkr6||_d|_|S t|tj �rV|j |_|j |_|S t|t t f�rx|j� \|_|_|S t|t��rZtj|�}|dkr�td| ��t|jd�p�d�}|jd�}|r�t|�}nvd}|jd�}|�rdt|� }|| t|� }||9 }|jd �} | �rBt| �} | d k�r4|d| 9 }n|d| 9 }|jd �d k�rb| }ntd ��nft|�t k�o�t|�kn �r�n@t|tj ��r�t|tj ��r�|j |j |j |j }}ntd��|d k�r�td| ��|�rBt|�t k�ot|�kn �r(tj||�} |d k �r2| } n t||�} || }|| }||_||_|S )a� Constructs a Rational.

Use this like: __op__, __rop__ = _operator_fallbacks(just_rational_op, operator.op) In general, we want to implement the arithmetic operations so that mixed-mode operations either call an implementation whose author knew about the types of both arguments, or convert both to the nearest built in type and do the operation there. In Fraction, that means that we define __add__ and __radd__ as: def __add__(self, other): # Both types have numerators/denominator attributes, # so do the operation directly if isinstance(other, (int, Fraction)): return Fraction(self.numerator * other.denominator + other.numerator * self.denominator, self.denominator * other.denominator) # float and complex don't have those operations, but we # know about those types, so special case them. elif isinstance(other, float): return float(self) + other elif isinstance(other, complex): return complex(self) + other # Let the other type take over. return NotImplemented def __radd__(self, other): # radd handles more types than add because there's # nothing left to fall back to. if isinstance(other, numbers.Rational): return Fraction(self.numerator * other.denominator + other.numerator * self.denominator, self.denominator * other.denominator) elif isinstance(other, Real): return float(other) + float(self) elif isinstance(other, Complex): return complex(other) + complex(self) return NotImplemented There are 5 different cases for a mixed-type addition on Fraction. I'll refer to all of the above code that doesn't refer to Fraction, float, or complex as "boilerplate". 'r' will be an instance of Fraction, which is a subtype of Rational (r : Fraction <: Rational), and b : B <: Complex. The first three involve 'r + b': 1. If B <: Fraction, int, float, or complex, we handle that specially, and all is well. 2. If Fraction falls back to the boilerplate code, and it were to return a value from __add__, we'd miss the possibility that B defines a more intelligent __radd__, so the boilerplate should return NotImplemented from __add__. In particular, we don't handle Rational here, even though we could get an exact answer, in case the other type wants to do something special. 3. If B <: Fraction, Python tries B.__radd__ before Fraction.__add__. This is ok, because it was implemented with knowledge of Fraction, so it can handle those instances before delegating to Real or Complex. The next two situations describe 'b + r'. We assume that b didn't know about Fraction in its implementation, and that it uses similar boilerplate code: 4. If B <: Rational, then __radd_ converts both to the builtin rational type (hey look, that's us) and proceeds. 5. Otherwise, __radd__ tries to find the nearest common base ABC, and fall back to its builtin type. Since this class doesn't subclass a concrete type, there's no implementation to fall back to, so we need to try as hard as possible to return an actual value, or the user will get a TypeError. c sP t |ttf�r�| |�S t |t�r0� t| �|�S t |t�rH� t| �|�S tS d S )N)r r r r" �complex�NotImplemented)r r )�fallback_operator�monomorphic_operatorr r �forwardv s z-Fraction._operator_fallbacks.<locals>.forward�__c sZ t |tj�r�|| �S t |tj�r4� t|�t| ��S t |tj�rR� t|�t| ��S tS d S )N)r r r ZRealr" �Complexr> r? )r r )r@ rA r r �reverse� s z-Fraction._operator_fallbacks.<locals>.reverseZ__r)r2 �__doc__)rA r@ rB rE r )r@ rA r �_operator_fallbacks& s P z Fraction._operator_fallbacksc C s, | j |j }}t| j| |j| || �S )za + b)r! r r )r r �da�dbr r r �_add� s z Fraction._addc C s, | j |j }}t| j| |j| || �S )za - b)r! r r )r r rH rI r r r �_sub� s z Fraction._subc C s t | j|j | j|j �S )za * b)r r r! )r r r r r �_mul� s z Fraction._mulc C s t | j|j | j|j �S )za / b)r r r! )r r r r r �_div� s z Fraction._divc C s t j| | �S )za // b)r �floor)r r r r r � __floordiv__� s zFraction.__floordiv__c C s t j|| �S )za // b)r rN )r r r r r � __rfloordiv__� s zFraction.__rfloordiv__c C s | | }| || S )za % br )r r �divr r r �__mod__� s zFraction.__mod__c C s || }|| | S )za % br )r r rQ r r r �__rmod__� s zFraction.__rmod__c C s� t |tj�r�|jdkr�|j}|dkr>t| j| | j| dd�S | jdkrft| j| | j| dd�S t| j | | j | dd�S q�t| �t|� S n t| �| S dS )z�a ** b If b is not an integer, the result will be a float or complex since roots are generally irrational.

The destination directory must not already exist. If exception(s) occur, an Error is raised with a list of reasons. If the optional symlinks flag is true, symbolic links in the source tree result in symbolic links in the destination tree; if it is false, the contents of the files pointed to by symbolic links are copied. If the file pointed by the symlink doesn't exist, an exception will be added in the list of errors raised in an Error exception at the end of the copy process. You can set the optional ignore_dangling_symlinks flag to true if you want to silence this exception. Notice that this has no effect on platforms that don't support os.symlink. The optional ignore argument is a callable. If given, it is called with the `src` parameter, which is the directory being visited by copytree(), and `names` which is the list of `src` contents, as returned by os.listdir(): callable(src, names) -> ignored_names Since copytree() is called recursively, the callable will be called once for each directory that is copied. It returns a list of names relative to the `src` directory that should not be copied. The optional copy_function argument is a callable that will be used to copy each file. It will be called with the source path and the destination path as arguments. By default, copy2() is used, but any function that supports the same signature (like copy()) can be used.

If ignore_errors is set, errors are ignored; otherwise, if onerror is set, it is called to handle the error with arguments (func, path, exc_info) where func is platform and implementation dependent; path is the argument to that function that caused it to fail; and exc_info is a tuple returned by sys.exc_info().

This is similar to the Unix "mv" command. Return the file or directory's destination. If the destination is a directory or a symlink to a directory, the source is moved inside the directory. The destination path must not already exist. If the destination already exists but is not a directory, it may be overwritten depending on os.rename() semantics. If the destination is on our current filesystem, then rename() is used. Otherwise, src is copied to the destination and then removed. Symlinks are recreated under the new name if os.rename() fails because of cross filesystem renames. The optional `copy_function` argument is a callable that will be used to copy the source or it will be delegated to `copytree`. By default, copy2() is used, but any function that supports the same signature (like copy()) can be used. A lot more could be done here... A look at a mv.c shows a lot of the issues this implementation glosses over.

If not provided, the current working directory is used. `format` is the archive format: one of "zip", "tar", "gztar", "bztar", or "xztar". Or any other registered format. If not provided, unpack_archive will use the filename extension and see if an unpacker was registered for that extension. In case none is found, a ValueError is raised.

For each of the two dimensions, the environment variable, COLUMNS and LINES respectively, is checked. If the variable is defined and the value is a positive integer, it is used. When COLUMNS or LINES is not defined, which is the common case, the terminal connected to sys.__stdout__ is queried by invoking os.get_terminal_size. If the terminal size cannot be successfully queried, either because the system doesn't support querying, or because we are not connected to a terminal, the value given in fallback parameter is used. Fallback defaults to (80, 24) which is the default size used by many terminal emulators. The value returned is a named tuple of type os.terminal_size.

According to POSIX, a program which has not called setlocale(LC_ALL, "") runs using the portable 'C' locale. Calling setlocale(LC_ALL, "") lets it use the default locale as defined by the LANG variable. Since we don't want to interfere with the current locale setting we thus emulate the behavior in the way described above. To maintain compatibility with other platforms, not only the LANG variable is tested, but a list of variables given as envvars parameter. The first found to be defined will be used. envvars defaults to the search path used in GNU gettext; it must always contain the variable name 'LANG'. Except for the code 'C', the language code corresponds to RFC 1766. code and encoding can be None in case the values cannot be determined. r NZwin32r' Z0xr� r� r< ) �_localeZ_getdefaultlocale� ImportError�AttributeError�sys�platform�windows_localer~ rs �os�environr[ r� )Zenvvarsr� r� r� r� �lookupZvariabler� r r r r s$ c C s( t | �}| tkr d|kr td��t|�S )ap Returns the current setting for the given locale category as tuple (language code, encoding). category may be one of the LC_* value except LC_ALL.

functions corresponding to the intrinsic operators of Python. For example, operator.add(x, y) is equivalent to the expression x+y. The function names are those used for special methods; variants without leading and trailing '__' are also provided for convenience. This is the pure Python implementation of the module. �abs�add�and_� attrgetter�concat�contains�countOf�delitem�eq�floordiv�ge�getitem�gt�iadd�iand�iconcat� ifloordiv�ilshift�imatmul�imod�imul�index�indexOf�inv�invert�ior�ipow�irshift�is_�is_not�isub� itemgetter�itruediv�ixor�le� length_hint�lshift�lt�matmul� methodcaller�mod�mul�ne�neg�not_�or_�pos�pow�rshift�setitem�sub�truediv�truth�xor� )r c C s | |k S )zSame as a < b.� )�a�br8 r8 � /usr/lib64/python3.6/operator.pyr& s c C s | |kS )zSame as a <= b.r8 )r9 r: r8 r8 r; r# s c C s | |kS )zSame as a == b.r8 )r9 r: r8 r8 r; r # s c C s | |kS )zSame as a != b.r8 )r9 r: r8 r8 r; r+ ' s c C s | |kS )zSame as a >= b.r8 )r9 r: r8 r8 r; r + s c C s | |kS )zSame as a > b.r8 )r9 r: r8 r8 r; r / s c C s | S )zSame as not a.r8 )r9 r8 r8 r; r- 5 s c C s | rdS dS )z*Return True if a is true, False otherwise.TFr8 )r9 r8 r8 r; r5 9 s c C s | |kS )zSame as a is b.r8 )r9 r: r8 r8 r; r = s c C s | |k S )zSame as a is not b.r8 )r9 r: r8 r8 r; r A s c C s t | �S )zSame as abs(a).)�_abs)r9 r8 r8 r; r G s c C s | | S )zSame as a + b.r8 )r9 r: r8 r8 r; r K s c C s | |@ S )zSame as a & b.r8 )r9 r: r8 r8 r; r O s c C s | | S )zSame as a // b.r8 )r9 r: r8 r8 r; r S s c C s | j � S )zSame as a.__index__().)� __index__)r9 r8 r8 r; r W s c C s | S )z Same as ~a.r8 )r9 r8 r8 r; r [ s c C s | |> S )zSame as a << b.r8 )r9 r: r8 r8 r; r% ` s c C s | | S )zSame as a % b.r8 )r9 r: r8 r8 r; r) d s c C s | | S )zSame as a * b.r8 )r9 r: r8 r8 r; r* h s c C s | | S )zSame as a @ b.r8 )r9 r: r8 r8 r; r' l s c C s | S )z Same as -a.r8 )r9 r8 r8 r; r, p s c C s | |B S )zSame as a | b.r8 )r9 r: r8 r8 r; r. t s c C s | S )z Same as +a.r8 )r9 r8 r8 r; r/ x s c C s | | S )zSame as a ** b.r8 )r9 r: r8 r8 r; r0 | s c C s | |?

Intended use is to place the following code in a package's __init__.py: from pkgutil import extend_path __path__ = extend_path(__path__, __name__) This will add to the package's __path__ all subdirectories of directories on sys.path named after the package. This is useful if one wants to distribute different parts of a single logical package as multiple directories. It also looks for *.pkg files beginning where * matches the name argument. This feature is similar to *.pth files (see site.py), except that it doesn't special-case lines starting with 'import'. A *.pkg file is trusted at face value: apart from checking for duplicates, all entries found in a *.pkg file are added to the path, regardless of whether they are exist the filesystem. (This is a feature.) If the input path is not a list (as is the case for frozen packages) it is returned unchanged. The input path is not modified; an extended copy is returned. Items are only appended to the copy at the end. It is assumed that sys.path is a sequence. Items of sys.path that are not (unicode or 8-bit) strings referring to existing directories are ignored. Unicode items of sys.path that cause errors when used as filenames may cause this function to raise an exception (in line with os.path.isdir() behavior). z.pkgNr, r r zCan't open %s: %s � �#)r� �listr� r2 r3 r) r� r r4 �strr r= r �submodule_search_locationsr �appendr@ rG �isfilerh rD �stderr�write�rstripr� )r4 r Z sname_pkgZparent_package�_Z final_nameZ search_path�dirr �portionsr} ZportionZpkgfiler| r� �liner r r r � sP ! c C s� t jj| �}|dkrdS |j}|dks2t|d� r6dS tjj| �pLt jj |�}|dksbt|d� rfdS |j d�}|j dt j j|j�� t j j|� }|j|�S )af Get a resource from a package. This is a wrapper round the PEP 302 loader get_data API. The package argument should be the name of a package, in standard module format (foo.bar). The resource argument should be in the form of a relative filename, using '/' as the path separator. The parent directory name '..' is not allowed, and nor is a rooted name (starting with a '/'). The function returns a binary string, which is the contents of the specified resource. For packages located in the filesystem, which have already been imported, this is the rough equivalent of d = os.path.dirname(sys.modules[package].__file__) data = open(os.path.join(d, resource), 'rb').read() If the package cannot be located or loaded, or it uses a PEP 302 loader which does not support get_data(), then None is returned.

Each instance of this class manages its own queue. No multi-threading is implied; you are supposed to hack that yourself, or use a single instance per application. Each instance is parametrized with two functions, one that is supposed to return the current time, one that is supposed to implement a delay. You can implement real-time scheduling by substituting time and sleep from built-in module time, or you can implement simulated time by writing your own functions. This can also be used to integrate scheduling with STDWIN events; the delay function is allowed to modify the queue. Time can be expressed as integers or floating point numbers, as long as it is consistent. Events are specified by tuples (time, priority, action, argument, kwargs). As in UNIX, lower priority numbers mean higher priority; in this way the queue can be maintained as a priority queue. Execution of the event means calling the action function, passing it the argument sequence in "argument" (remember that in Python, multiple function arguments are be packed in a sequence) and keyword parameters in "kwargs". The action function may be an instance method so it has another way to reference private data (besides global variables). � N)� namedtuple)� monotonic� schedulerc @ s8 e Zd Zg Zdd� Zdd� Zdd� Zdd� Zd d � Zd S ) �Eventc C s | j | jf|j |jfkS )N)�time�priority)�s�o� r � /usr/lib64/python3.6/sched.py�__eq__' s z Event.__eq__c C s | j | jf|j |jfk S )N)r r )r r r r r �__lt__( s z Event.__lt__c C s | j | jf|j |jfkS )N)r r )r r r r r �__le__) s z Event.__le__c C s | j | jf|j |jfkS )N)r r )r r r r r �__gt__* s z Event.__gt__c C s | j | jf|j |jfkS )N)r r )r r r r r �__ge__+ s z Event.__ge__N) �__name__� __module__� __qualname__� __slots__r r r r r r r r r r % s r z(time, priority, action, argument, kwargszaNumeric type compatible with the return value of the timefunc function passed to the constructor.zSEvents scheduled for the same time will be executed in the order of their priority.z?Executing the event means executing action(*argument, **kwargs)zGargument is a sequence holding the positional arguments for the action.zDkwargs is a dictionary holding the keyword arguments for the action.c @ s^ e Zd Zeejfdd�Zf efdd�Zf efdd�Z dd� Z d d � Z dd d �Z e dd� �ZdS )r c C s g | _ tj� | _|| _|| _dS )zGInitialize a new instance, passing the time and delay functionsN)�_queue� threading�RLock�_lock�timefunc� delayfunc)�selfr r r r r �__init__< s zscheduler.__init__c C s@ |t kr i }t|||||�}| j� tj| j|� W dQ R X |S )z�Enter a new event in the queue at an absolute time.

If blocking is False executes the scheduled events due to expire soonest (if any) and then return the deadline of the next scheduled call in the scheduler. When there is a positive delay until the first event, the delay function is called and the event is left in the queue; otherwise, the event is removed from the queue and executed (its action function is called, passing it the argument). If the delay function returns prematurely, it is simply restarted. It is legal for both the delay function and the action function to modify the queue or to raise an exception; exceptions are not caught but the scheduler's state remains well-defined so run() may be called again. A questionable hack is added to allow other threads to run: just after an event is executed, a delay of 0 is executed, to avoid monopolizing the CPU when other threads are also runnable. r TFN)r r r r r �heappop)r Zblocking�lock�qr r �popr r r r! r" Znowr% r r r �runk s* z scheduler.runc C s: | j � | jdd� }W dQ R X tttj|gt|� ��S )z�An ordered list of upcoming events.

This module provides internationalization (I18N) and localization (L10N) support for your Python programs by providing an interface to the GNU gettext message catalog library. I18N refers to the operation by which a program is made aware of multiple languages. L10N refers to the adaptation of your program, once internationalized, to the local language and cultural habits. � N)�ENOENT�NullTranslations�GNUTranslations�Catalog�find� translation�install� textdomain�bindtextdomain�bind_textdomain_codeset�dgettext� dngettext�gettext�lgettext� ldgettext� ldngettext� lngettext�ngettextZshare�localea� (?P<WHITESPACES>[ \t]+) | # spaces and horizontal tabs (?P<NUMBER>[0-9]+\b) | # decimal integer (?P<NAME>n\b) | # only n is allowed (?P<PARENTHESIS>[()]) | (?P<OPERATOR>[-*/%+?:]|[><!]=?|==|&&|\|\|) | # !, *, /, %, +, -, <, >, # <=, >=, ==, !=, &&, ||, # ?

Optional casefold is a flag specifying whether a lowercase alphabet is acceptable as input. For security purposes, the default is False. RFC 3548 allows for optional mapping of the digit 0 (zero) to the letter O (oh), and for optional mapping of the digit 1 (one) to either the letter I (eye) or letter L (el). The optional argument map01 when not None, specifies which letter the digit 1 should be mapped to (when map01 is not None, the digit 0 is always mapped to the letter O).

This will stop in the first function call in <a statement>. Alternatively, if a statement terminated with an unhandled exception, you can use pdb's post-mortem facility to inspect the contents of the traceback: >>> <a statement> <exception traceback> >>> import pdb >>> pdb.pm() The commands recognized by the debugger are listed in the next section. Most can be abbreviated as indicated; e.g., h(elp) means that 'help' can be typed as 'h' or 'help' (but not as 'he' or 'hel', nor as 'H' or 'Help' or 'HELP'). Optional arguments are enclosed in square brackets. Alternatives in the command syntax are separated by a vertical bar (|). A blank line repeats the previous command literally, except for 'list', where it lists the next 11 lines. Commands that the debugger doesn't recognize are assumed to be Python statements and are executed in the context of the program being debugged. Python statements can also be prefixed with an exclamation point ('!'). This is a powerful way to inspect the program being debugged; it is even possible to change variables or call functions. When an exception occurs in such a statement, the exception name is printed but the debugger's state is not changed. The debugger supports aliases, which can save typing. And aliases can have parameters (see the alias help entry) which allows one a certain level of adaptability to the context under examination. Multiple commands may be entered on a single line, separated by the pair ';;'. No intelligence is applied to separating the commands; the input is split at the first ';;', even if it is in the middle of a quoted string. If a file ".pdbrc" exists in your home directory or in the current directory, it is read in and executed as if it had been typed at the debugger prompt. This is particularly useful for aliases. If both files exist, the one in the home directory is read first and aliases defined there can be overridden by the local file. This behavior can be disabled by passing the "readrc=False" argument to the Pdb constructor. Aside from aliases, the debugger is not directly programmable; but it is implemented as a class from which you can derive your own debugger class, which you can make as fancy as you like.

(com) end (Pdb) Specify a list of commands for breakpoint number bpnumber. The commands themselves are entered on the following lines. Type a line containing just 'end' to terminate the commands. The commands are executed when the breakpoint is hit. To remove all commands from a breakpoint, type commands and follow it immediately with end; that is, give no commands. With no bpnumber argument, commands refers to the last breakpoint set. You can use breakpoint commands to start your program up again. Simply use the continue command, or step, or any other command that resumes execution. Specifying any command resuming execution (currently continue, step, next, return, jump, quit and their abbreviations) terminates the command list (as if that command was immediately followed by end). This is because any time you resume execution (even with a simple next or step), you may encounter another breakpoint -- which could have its own command list, leading to ambiguities about which list to execute. If you use the 'silent' command in the command list, the usual message about stopping at a breakpoint is not printed. This may be desirable for breakpoints that are to print a specific message and then continue. If none of the other commands print anything, you will see no sign that the breakpoint was reached. r z.Usage: commands [bnum] ... endNTFz(com) r r� z1command definition aborted, old commands restored)�lenr4 r� r� �intr� rM rI rJ rK r9 rL r� rQ )r. r� ZbnumZold_command_defsZ prompt_backr r r � do_commands s@ % zPdb.do_commandsr c C s@ |s<| j r8| jd� x"tjjD ]}|r | j|j� � q W dS d}d}d}|jd�}|dkr~||d d� j� }|d|� j� }|j d�}d} |dk�r|d|� j� }| j |�} | s�| j d| � dS | }||d d� j� }y t |�}W n$ t k �r | j d| � dS X n�y t |�}W n� t k �r� yt|| jj| j�} W n |} Y nX y.t| d ��rl| j} | j} | j} | j}| j}W n@ | j|�\} }}| �s�| j d | � dS | } t |�}Y nX Y nX |�s�| j� }| j||�}|�r<| j||||| �}|�r| j |� n*| j ||�d }| jd |j |j |j f � dS ) a� b(reak) [ ([filename:]lineno | function) [, condition] ] Without argument, list all breaks.

Raise OSError upon failure. file is either a text or byte string giving the name (and the path if the file isn't in the current working directory) of the file to be opened or an integer file descriptor of the file to be wrapped. (If a file descriptor is given, it is closed when the returned I/O object is closed, unless closefd is set to False.) mode is an optional string that specifies the mode in which the file is opened. It defaults to 'r' which means open for reading in text mode. Other common values are 'w' for writing (truncating the file if it already exists), 'x' for exclusive creation of a new file, and 'a' for appending (which on some Unix systems, means that all writes append to the end of the file regardless of the current seek position). In text mode, if encoding is not specified the encoding used is platform dependent. (For reading and writing raw bytes use binary mode and leave encoding unspecified.) The available modes are: ========= =============================================================== Character Meaning --------- --------------------------------------------------------------- 'r' open for reading (default) 'w' open for writing, truncating the file first 'x' create a new file and open it for writing 'a' open for writing, appending to the end of the file if it exists 'b' binary mode 't' text mode (default) '+' open a disk file for updating (reading and writing) 'U' universal newline mode (deprecated) ========= =============================================================== The default mode is 'rt' (open for reading text). For binary random access, the mode 'w+b' opens and truncates the file to 0 bytes, while 'r+b' opens the file without truncation. The 'x' mode implies 'w' and raises an `FileExistsError` if the file already exists. Python distinguishes between files opened in binary and text modes, even when the underlying operating system doesn't. Files opened in binary mode (appending 'b' to the mode argument) return contents as bytes objects without any decoding. In text mode (the default, or when 't' is appended to the mode argument), the contents of the file are returned as strings, the bytes having been first decoded using a platform-dependent encoding or using the specified encoding if given. 'U' mode is deprecated and will raise an exception in future versions of Python. It has no effect in Python 3. Use newline to control universal newlines mode. buffering is an optional integer used to set the buffering policy. Pass 0 to switch buffering off (only allowed in binary mode), 1 to select line buffering (only usable in text mode), and an integer > 1 to indicate the size of a fixed-size chunk buffer. When no buffering argument is given, the default buffering policy works as follows: * Binary files are buffered in fixed-size chunks; the size of the buffer is chosen using a heuristic trying to determine the underlying device's "block size" and falling back on `io.DEFAULT_BUFFER_SIZE`. On many systems, the buffer will typically be 4096 or 8192 bytes long. * "Interactive" text files (files for which isatty() returns True) use line buffering. Other text files use the policy described above for binary files. encoding is the str name of the encoding used to decode or encode the file. This should only be used in text mode. The default encoding is platform dependent, but any encoding supported by Python can be passed. See the codecs module for the list of supported encodings. errors is an optional string that specifies how encoding errors are to be handled---this argument should not be used in binary mode. Pass 'strict' to raise a ValueError exception if there is an encoding error (the default of None has the same effect), or pass 'ignore' to ignore errors. (Note that ignoring encoding errors can lead to data loss.) See the documentation for codecs.register for a list of the permitted encoding error strings. newline is a string controlling how universal newlines works (it only applies to text mode). It can be None, '', '\n', '\r', and '\r\n'. It works as follows: * On input, if newline is None, universal newlines mode is enabled. Lines in the input can end in '\n', '\r', or '\r\n', and these are translated into '\n' before being returned to the caller. If it is '', universal newline mode is enabled, but line endings are returned to the caller untranslated. If it has any of the other legal values, input lines are only terminated by the given string, and the line ending is returned to the caller untranslated. * On output, if newline is None, any '\n' characters written are translated to the system default line separator, os.linesep. If newline is '', no translation takes place. If newline is any of the other legal values, any '\n' characters written are translated to the given string. closedfd is a bool. If closefd is False, the underlying file descriptor will be kept open when the file is closed. This does not work when a file name is given and must be True in that case. The newly created file is non-inheritable. A custom opener can be used by passing a callable as *opener*. The underlying file descriptor for the file object is then obtained by calling *opener* with (*file*, *flags*). *opener* must return an open file descriptor (passing os.open as *opener* results in functionality similar to passing None). open() returns a file object whose type depends on the mode, and through which the standard file operations such as reading and writing are performed. When open() is used to open a file in a text mode ('w', 'r', 'wt', 'rt', etc.), it returns a TextIOWrapper. When used to open a file in a binary mode, the returned class varies: in read binary mode, it returns a BufferedReader; in write binary and append binary modes, it returns a BufferedWriter, and in read/write mode, it returns a BufferedRandom. It is also possible to use a string or bytearray as a file for both reading and writing. For strings StringIO can be used like a file opened in a text mode, and for bytes a BytesIO can be used like a file opened in a binary mode. zinvalid file: %rzinvalid mode: %rzinvalid buffering: %rNzinvalid encoding: %rzinvalid errors: %rzaxrwb+tU�xr �w�a�+�t�b�Uz4mode U cannot be combined with 'x', 'w', 'a', or '+'r z'U' mode is deprecatedr Tz'can't have text and binary mode at oncer z)can't have read/write/append mode at oncez/must have exactly one of read/write/append modez-binary mode doesn't take an encoding argumentz+binary mode doesn't take an errors argumentz+binary mode doesn't take a newline argument� )�openerFzinvalid buffering sizez can't have unbuffered text I/Ozunknown mode: %r���)� isinstance�int�os�fspath�str�bytes� TypeError�set�len� ValueError�warnings�warn�DeprecationWarning�FileIO�isatty�DEFAULT_BUFFER_SIZE�fstat�fileno� st_blksize�OSError�AttributeError�BufferedRandom�BufferedWriter�BufferedReader� TextIOWrapper�mode�close)�filer2 � buffering�encoding�errors�newline�closefdr ZmodesZcreatingZreadingZwritingZ appendingZupdating�textZbinaryr# �raw�result�line_bufferingZbs�buffer� r? � /usr/lib64/python3.6/_pyio.py�open( s� { > rA c @ s e Zd ZdZdd� ZdS )� DocDescriptorz%Helper for builtins.open.__doc__ c C s dt j S )Nz\open(file, mode='r', buffering=-1, encoding=None, errors=None, newline=None, closefd=True) )rA �__doc__)�self�obj�typr? r? r@ �__get__� s zDocDescriptor.__get__N)�__name__� __module__� __qualname__rC rG r? r? r? r@ rB � s rB c @ s e Zd ZdZe� Zdd� ZdS )� OpenWrapperz�Wrapper for builtins.open Trick so that open won't become a bound method when stored as a class variable (as dbm.dumb does).

There is no public constructor. This class provides dummy implementations for many methods that derived classes can override selectively; the default implementations represent a file that cannot be read, written or seeked. Even though IOBase does not declare read, readinto, or write because their signatures will vary, implementations and clients should consider those methods part of the interface. Also, implementations may raise UnsupportedOperation when operations they do not support are called. The basic type used for binary data read from or written to a file is bytes. Other bytes-like objects are accepted as method arguments too. In some cases (such as readinto), a writable object is required. Text I/O classes work with str data. Note that calling any method (even inquiries) on a closed stream is undefined. Implementations may raise OSError in this case. IOBase (and its subclasses) support the iterator protocol, meaning that an IOBase object can be iterated over yielding the lines in a stream. IOBase also supports the :keyword:`with` statement. In this example, fp is closed after the suite of the with statement is complete: with open('spam.txt', 'r') as fp: fp.write('Spam and eggs!') c C s t d| jj|f ��dS )z@Internal: raise an OSError exception for unsupported operations.z%s.%s() not supportedN)rP � __class__rH )rD �namer? r? r@ � _unsupported@ s zIOBase._unsupportedr c C s | j d� dS )a$ Change stream position. Change the stream position to byte offset pos. Argument pos is interpreted relative to the position indicated by whence.

The main difference with RawIOBase is that the read() method supports omitting the size argument, and does not have a default implementation that defers to readinto(). In addition, read(), readinto() and write() may raise BlockingIOError if the underlying raw stream is in non-blocking mode and not ready; unlike their raw counterparts, they will never return None. A typical implementation should not inherit from a RawIOBase implementation, but wrap one. Nc C s | j d� dS )a� Read and return up to size bytes, where size is an int. If the argument is omitted, None, or negative, reads and returns all data until EOF. If the argument is positive, and the underlying raw stream is not 'interactive', multiple raw reads may be issued to satisfy the byte count (unless EOF is reached first). But for interactive raw streams (XXX and for pipes?), at most one raw read will be issued, and a short result does not imply that EOF is imminent. Returns an empty bytes array on EOF.

The mode can be 'r' (default), 'w', 'x' or 'a' for reading, writing, exclusive creation or appending. The file will be created if it doesn't exist when opened for writing or appending; it will be truncated when opened for writing. A FileExistsError will be raised if it already exists when opened for creating. Opening a file for creating implies writing so this mode behaves in a similar way to 'w'. Add a '+' to the mode to allow simultaneous reading and writing. A custom opener can be used by passing a callable as *opener*. The underlying file descriptor for the file object is then obtained by calling opener with (*name*, *flags*). *opener* must return an open file descriptor (passing os.open as *opener* results in functionality similar to passing None). r Nr z$integer argument expected, got floatznegative file descriptorzinvalid mode: %szxrwab+c s s | ]}|d kV qdS )ZrwaxNr? )�.0�cr? r? r@ � <genexpr>� s z"FileIO.__init__.<locals>.<genexpr>r zKMust have exactly one of create/read/write/append mode and at most one plusr Tr r r �O_BINARYZ O_NOINHERIT� O_CLOEXECz'Cannot use closefd=False with file namei� z expected integer from openerzNegative file descriptorFr+ r r ),�_fd�_closefdr r3 r �floatr r r" r r �sum�count�_created� _writable�O_EXCL�O_CREAT� _readable�O_TRUNC� _appending�O_APPEND�O_RDWR�O_RDONLY�O_WRONLY�getattrrA r, �set_inheritabler) �stat�S_ISDIR�st_mode�IsADirectoryErrorr� ZEISDIRr� r- �_blksizer( �_setmoder� rS �lseekr ) rD r4 r2 r9 r �fd�flagsZnoinherit_flagZowned_fdZfdfstatr? r? r@ r� w s� $ zFileIO.__init__c C sD | j dkr@| jr@| j r@dd l}|jd| f td| d� | j� d S )Nr zunclosed file %rr )� stacklevel�source)r� r� re r# r$ �ResourceWarningr3 )rD r# r? r? r@ r] � s zFileIO.__del__c C s t d| jj��d S )Nz cannot serialize '%s' object)r rR rH )rD r? r? r@ r� � s zFileIO.__getstate__c C sl d| j j| j jf }| jr"d| S y | j}W n& tk rR d|| j| j| jf S X d||| j| jf S d S )Nz%s.%sz <%s [closed]>z <%s fd=%d mode=%r closefd=%r>z <%s name=%r mode=%r closefd=%r>) rR rI rJ re rS r- r� r2 r� )rD � class_namerS r? r? r@ r� � s zFileIO.__repr__c C s | j std��d S )NzFile not open for reading)r� rP )rD r? r? r@ rb s zFileIO._checkReadablec C s | j std��d S )NzFile not open for writing)r� rP )rD r_ r? r? r@ rd s zFileIO._checkWritablec C sP | j � | j� |dks |dk r(| j� S ytj| j|�S tk rJ dS X dS )z�Read at most size bytes, returned as bytes.

It defaults to locale.getpreferredencoding(False). errors determines the strictness of encoding and decoding (see the codecs.register) and defaults to "strict". newline can be None, '', '\n', '\r', or '\r\n'. It controls the handling of line endings. If it is None, universal newlines is enabled. With this enabled, on input, the lines endings '\n', '\r', or '\r\n' are translated to '\n' before being returned to the caller. Conversely, on output, '\n' is translated to the system default line separator, os.linesep. If newline is any other of its legal values, that newline becomes the newline when the file is read and it is returned untranslated. On output, '\n' is converted to the newline. If line_buffering is True, a call to flush is implied when a call to write contains a newline character. i NFc C s� |d k r&t |t� r&tdt|�f ��|dkr<td|f ��|d kr�ytj|j� �}W n tt fk rn Y nX |d kr�y dd l }W n t k r� d}Y n X |j d �}t |t�s�td | ��t j|�js�d }t|| ��|d kr�d }nt |t��s td | ��|| _|| _|| _|| _| | _|d k| _|| _|dk| _|�pDtj| _d | _d | _ d| _ d| _ d | _ | j j!� | _"| _#t$| j d�| _%d| _&| j"�r�| j'� �r�| j j(� } | dk�r�y| j)� j*d� W n tk �r� Y nX d S )Nzillegal newline type: %rr r� r� � zillegal newline value: %rr �asciiFzinvalid encoding: %rzG%r is not a text encoding; use codecs.open() to handle arbitrary codecsr� zinvalid errors: %rr� g )Nr r� r� r )+r r r �typer" r �device_encodingr* r- rP �locale� ImportError�getpreferredencodingr� �lookup�_is_text_encoding� LookupErrorr� �_line_buffering� _encoding�_errors�_readuniversal�_readtranslate�_readnl�_writetranslate�linesep�_writenl�_encoder�_decoder�_decoded_chars�_decoded_chars_used� _snapshotr> r^ r� �_tellingro � _has_read1� _b2cratiorc rX � _get_encoderr ) rD r> r6 r7 r8 r= � write_throughr r_ �positionr? r? r@ r� w s` zTextIOWrapper.__init__c C s� dj | jj| jj�}y | j}W n tk r2 Y nX |dj |�7 }y | j}W n tk r` Y nX |dj |�7 }|dj | j� S )Nz<{}.{}z name={0!r}z mode={0!r}z encoding={0!r}>)r� rR rI rJ rS r� r2 r6 )rD r< rS r2 r? r? r@ r� � s zTextIOWrapper.__repr__c C s | j S )N)r )rD r? r? r@ r6 � s zTextIOWrapper.encodingc C s | j S )N)r )rD r? r? r@ r7 � s zTextIOWrapper.errorsc C s | j S )N)r )rD r? r? r@ r= � s z TextIOWrapper.line_bufferingc C s | j S )N)r� )rD r? r? r@ r> � s zTextIOWrapper.bufferc C s | j rtd��| jS )Nz I/O operation on closed file.)re r" r� )rD r? r? r@ r^ � s zTextIOWrapper.seekablec C s | j j� S )N)r> ra )rD r? r? r@ ra � s zTextIOWrapper.readablec C s | j j� S )N)r> rc )rD r? r? r@ rc � s zTextIOWrapper.writablec C s | j j� | j| _d S )N)r> r[ r� r% )rD r? r? r@ r[ � s zTextIOWrapper.flushc C s0 | j d k r,| j r,z | j� W d | j j� X d S )N)r> re r[ r3 )rD r? r? r@ r3 � s zTextIOWrapper.closec C s | j jS )N)r> re )rD r? r? r@ re � s zTextIOWrapper.closedc C s | j jS )N)r> rS )rD r? r? r@ rS � s zTextIOWrapper.namec C s | j j� S )N)r> r* )rD r? r? r@ r* � s zTextIOWrapper.filenoc C s | j j� S )N)r> r' )rD r? r? r@ r' � s zTextIOWrapper.isattyc C s� | j rtd��t|t�s(td|jj ��t|�}| js<| j oBd|k}|rf| jrf| j dkrf|j d| j �}| j pr| j � }|j|�}| jj|� | j r�|s�d|kr�| j� | jd� d| _| jr�| jj� |S )z Write data, where s is a strzwrite to closed filez can't write %s to text streamr� r� r N)re r" r r r rR rH r! r r r r� r r( �encoder> r} r[ �_set_decoded_charsr$ r! r )rD r� ZlengthZhaslf�encoderr r? r? r@ r} s& zTextIOWrapper.writec C s t j| j�}|| j�| _| jS )N)r� �getincrementalencoderr r r )rD Z make_encoderr? r? r@ r( s zTextIOWrapper._get_encoderc C s2 t j| j�}|| j�}| jr(t|| j�}|| _|S )N)r� �getincrementaldecoderr r r r� r r! )rD Z make_decoderr� r? r? r@ � _get_decoder s zTextIOWrapper._get_decoderc C s || _ d| _dS )z Set the _decoded_chars buffer.r N)r" r# )rD �charsr? r? r@ r, ) s z TextIOWrapper._set_decoded_charsc C sF | j }|dkr | j|d� }n| j||| � }| j t|�7 _ |S )z'Advance into the _decoded_chars buffer.N)r# r" r! )rD rl �offsetr1 r? r? r@ �_get_decoded_chars. s z TextIOWrapper._get_decoded_charsc C s$ | j |k rtd��| j |8 _ dS )z!Rewind the _decoded_chars buffer.z"rewind decoded_chars out of boundsN)r# �AssertionError)rD rl r? r? r@ �_rewind_decoded_chars8 s z#TextIOWrapper._rewind_decoded_charsc C s� | j dkrtd��| jr&| j j� \}}| jr<| jj| j�}n| jj| j�}| }| j j ||�}| j |� |r�t |�t | j � | _ nd| _ | jr�||| f| _| S )zQ Read and decode the next chunk of data from the BufferedReader.

An IFF chunk (used in formats such as AIFF, TIFF, RMFF (RealMedia File Format)) has the following structure: +----------------+ | ID (4 bytes) | +----------------+ | size (4 bytes) | +----------------+ | data | | ... | +----------------+ The ID is a 4-byte string which identifies the type of chunk. The size field (a 32-bit value, encoded using big-endian byte order) gives the size of the whole chunk, including the 8-byte header. Usually an IFF-type file consists of one or more chunks. The proposed usage of the Chunk class defined here is to instantiate an instance at the start of each chunk and read from the instance until it reaches the end, after which a new instance can be instantiated. At the end of the file, creating a new instance will fail with an EOFError exception. Usage: while True: try: chunk = Chunk(file) except EOFError: break chunktype = chunk.getname() while True: data = chunk.read(nbytes) if not data: pass # do something with data The interface is file-like. The implemented methods are: read, close, seek, tell, isatty. Extra methods are: skip() (called by close, skips to the end of the chunk), getname() (returns the name (ID) of the chunk) The __init__ method has one required argument, a file-like object (including a chunk instance), and one optional argument, a flag which specifies whether or not chunks are aligned on 2-byte boundaries. The default is 1, i.e. aligned. c @ sZ e Zd Zddd�Zdd� Zdd� Zd d � Zd d � Zddd�Zdd� Z ddd�Z dd� Z dS ) �ChunkTFc C s� dd l }d| _|| _|r d}nd}|| _|jd�| _t| j�dk rFt�y |j|d |jd��d | _ W n |j k r� t�Y nX |r�| j d | _ d| _ y| jj � | _ W n ttfk r� d| _Y nX d| _d S ) N� F�>�<� �L� T)�struct�closed�align�file�read� chunkname�len�EOFErrorZ unpack_from� chunksize�error� size_read�tell�offset�AttributeError�OSError�seekable)�selfr r Z bigendianZ inclheaderr Zstrflag� r � /usr/lib64/python3.6/chunk.py�__init__4 s, zChunk.__init__c C s | j S )z*Return the name (ID) of the current chunk.)r )r r r r �getnameN s z Chunk.getnamec C s | j S )z%Return the size of the current chunk.)r )r r r r �getsizeR s z Chunk.getsizec C s | j s z | j� W d d| _ X d S )NT)r �skip)r r r r �closeV s z Chunk.closec C s | j rtd��dS )Nz I/O operation on closed fileF)r � ValueError)r r r r �isatty] s z Chunk.isattyr c C sv | j rtd��| js td��|dkr0|| j }n|dkrB|| j }|dk sT|| jkrXt�| jj| j | d� || _dS )z�Seek to specified position into the chunk.

(Note that this module provides a Python version of the threading.local class. Depending on the version of Python you're using, there may be a faster one available. You should always import the `local` class from `threading`.) Thread-local objects support the management of thread-local data. If you have data that you want to be local to a thread, simply create a thread-local object and use its attributes: >>> mydata = local() >>> mydata.number = 42 >>> mydata.number 42 You can also access the local-object's dictionary: >>> mydata.__dict__ {'number': 42} >>> mydata.__dict__.setdefault('widgets', []) [] >>> mydata.widgets [] What's important about thread-local objects is that their data are local to a thread. If we access the data in a different thread: >>> log = [] >>> def f(): ... items = sorted(mydata.__dict__.items()) ... log.append(items) ... mydata.number = 11 ... log.append(mydata.number) >>> import threading >>> thread = threading.Thread(target=f) >>> thread.start() >>> thread.join() >>> log [[], 11] we get different data. Furthermore, changes made in the other thread don't affect data seen in this thread: >>> mydata.number 42 Of course, values you get from a local object, including a __dict__ attribute, are for whatever thread was current at the time the attribute was read. For that reason, you generally don't want to save these values across threads, as they apply only to the thread they came from. You can create custom local objects by subclassing the local class: >>> class MyLocal(local): ... number = 2 ... def __init__(self, **kw): ... self.__dict__.update(kw) ... def squared(self): ... return self.number ** 2 This can be useful to support default values, methods and initialization. Note that if you define an __init__ method, it will be called each time the local object is used in a separate thread. This is necessary to initialize each thread's dictionary. Now if we create a local object: >>> mydata = MyLocal(color='red') Now we have a default number: >>> mydata.number 2 an initial color: >>> mydata.color 'red' >>> del mydata.color And a method that operates on the data: >>> mydata.squared() 4 As before, we can access the data in a separate thread: >>> log = [] >>> thread = threading.Thread(target=f) >>> thread.start() >>> thread.join() >>> log [[('color', 'red')], 11] without affecting this thread's data: >>> mydata.number 2 >>> mydata.color Traceback (most recent call last): ... AttributeError: 'MyLocal' object has no attribute 'color' Note that subclasses can define slots, but they are not thread local. They are shared across threads: >>> class MyLocal(local): ... __slots__ = 'number' >>> mydata = MyLocal() >>> mydata.number = 42 >>> mydata.color = 'red' So, the separate thread: >>> thread = threading.Thread(target=f) >>> thread.start() >>> thread.join() affects what we see: >>> mydata.number 11 >>> del mydata � )�ref)�contextmanager�localc @ s, e Zd ZdZdZdd� Zd d � Zd d � Zd S )� _localimplz#A class managing thread-local dicts�key�dicts� localargs� locallock� __weakref__c C s dt t| �� | _i | _d S )Nz _threading_local._localimpl.)�str�idr r )�self� r �(/usr/lib64/python3.6/_threading_local.py�__init__� s z_localimpl.__init__c C s t � }| jt|� d S )zPReturn the dict for the current thread.

In the case of MandatoryReleases that have not yet occurred, MandatoryRelease predicts the release in which the feature will become part of the language. Else MandatoryRelease records when the feature became part of the language; in releases at or after that, modules no longer need from __future__ import FeatureName to use the feature in question, but may continue to use such imports. MandatoryRelease may also be None, meaning that a planned feature got dropped. Instances of class _Feature have two corresponding methods, .getOptionalRelease() and .getMandatoryRelease(). CompilerFlag is the (bitfield) flag that should be passed in the fourth argument to the builtin function compile() to enable the feature in dynamically compiled code. This flag is stored in the .compiler_flag attribute on _Future instances. These values must match the appropriate #defines of CO_xxx flags in Include/compile.h.

This module provides immutable UUID objects (class UUID) and the functions uuid1(), uuid3(), uuid4(), uuid5() for generating version 1, 3, 4, and 5 UUIDs as specified in RFC 4122. If all you want is a unique ID, you should probably call uuid1() or uuid4(). Note that uuid1() may compromise privacy since it creates a UUID containing the computer's network address. uuid4() creates a random UUID. Typical usage: >>> import uuid # make a UUID based on the host ID and current time >>> uuid.uuid1() # doctest: +SKIP UUID('a8098c1a-f86e-11da-bd1a-00112444be1e') # make a UUID using an MD5 hash of a namespace UUID and a name >>> uuid.uuid3(uuid.NAMESPACE_DNS, 'python.org') UUID('6fa459ea-ee8a-3ca4-894e-db77e160355e') # make a random UUID >>> uuid.uuid4() # doctest: +SKIP UUID('16fd2706-8baf-433b-82eb-8c7fada847da') # make a UUID using a SHA-1 hash of a namespace UUID and a name >>> uuid.uuid5(uuid.NAMESPACE_DNS, 'python.org') UUID('886313e1-3b8a-5372-9b90-0c9aee199e5d') # make a UUID from a string of hex digits (braces and hyphens ignored) >>> x = uuid.UUID('{00010203-0405-0607-0809-0a0b0c0d0e0f}') # convert a UUID to a string of hex digits in standard form >>> str(x) '00010203-0405-0607-0809-0a0b0c0d0e0f' # get the raw 16 bytes of the UUID >>> x.bytes b'\x00\x01\x02\x03\x04\x05\x06\x07\x08\t\n\x0b\x0c\r\x0e\x0f' # make a UUID from a 16-byte string >>> uuid.UUID(bytes=x.bytes) UUID('00010203-0405-0607-0809-0a0b0c0d0e0f') � NzKa-Ping Yee <ping@zesty.ca>z reserved for NCS compatibilityzspecified in RFC 4122z$reserved for Microsoft compatibilityz reserved for future definitionc @ s e Zd ZdZd7dd�Zdd� Zdd� Zd d � Zd d � Zd d� Z dd� Z dd� Z dd� Z dd� Z dd� Zedd� �Zedd � �Zed d � �Zed d � �Zed!d"� �Zed#d$� �Zed%d&� �Zed'd(� �Zed)d*� �Zed+d,� �Zed-d.� �Zed/d0� �Zed1d2� �Z ed3d4� �Z ed5d6� �Z dS )8�UUIDa� Instances of the UUID class represent UUIDs as specified in RFC 4122. UUID objects are immutable, hashable, and usable as dictionary keys. Converting a UUID to a string with str() yields something in the form '12345678-1234-1234-1234-123456789abc'. The UUID constructor accepts five possible forms: a similar string of hexadecimal digits, or a tuple of six integer fields (with 32-bit, 16-bit, 16-bit, 8-bit, 8-bit, and 48-bit values respectively) as an argument named 'fields', or a string of 16 bytes (with all the integer fields in big-endian order) as an argument named 'bytes', or a string of 16 bytes (with the first three fields in little-endian order) as an argument named 'bytes_le', or a single 128-bit integer as an argument named 'int'. UUIDs have these read-only attributes: bytes the UUID as a 16-byte string (containing the six integer fields in big-endian byte order) bytes_le the UUID as a 16-byte string (with time_low, time_mid, and time_hi_version in little-endian byte order) fields a tuple of the six integer fields of the UUID, which are also available as six individual attributes and two derived attributes: time_low the first 32 bits of the UUID time_mid the next 16 bits of the UUID time_hi_version the next 16 bits of the UUID clock_seq_hi_variant the next 8 bits of the UUID clock_seq_low the next 8 bits of the UUID node the last 48 bits of the UUID time the 60-bit timestamp clock_seq the 14-bit sequence number hex the UUID as a 32-character hexadecimal string int the UUID as a 128-bit integer urn the UUID as a URN as specified in RFC 4122 variant the UUID variant (one of the constants RESERVED_NCS, RFC_4122, RESERVED_MICROSOFT, or RESERVED_FUTURE) version the UUID version number (1 through 5, meaningful only when the variant is RFC_4122) Nc C s� |||||gj d�dkr td��|dk rl|jdd�jdd�}|jd�jdd�}t|�d krbtd ��t|d �}|dk r�t|�d kr�td ��|d(dd)� |d*d+d,� |d-d.d/� |dd� }|dk � r�t|�d kr�td��tj|dd�}|dk �r"t|�dk�r td��|\}}} } } } d| k�o.d0k n �s>td��d| k�oRd1k n �sbtd��d| k�ovd2k n �s�td��d| k�o�d3k n �s�td��d| k�o�d4k n �s�td��d| k�o�d5k n �s�td��| d> | B } |d > |d > B | d > B | d> B | B }|dk �rTd| k�oDd d > k n �sTtd ��|dk �r�d | k�ord!kn �s�td"��|d7M }|d8O }|d:M }||d&> O }|| jd'< dS );am Create a UUID from either a string of 32 hexadecimal digits, a string of 16 bytes as the 'bytes' argument, a string of 16 bytes in little-endian order as the 'bytes_le' argument, a tuple of six integers (32-bit time_low, 16-bit time_mid, 16-bit time_hi_version, 8-bit clock_seq_hi_variant, 8-bit clock_seq_low, 48-bit node) as the 'fields' argument, or a single 128-bit integer as the 'int' argument. When a string of hex digits is given, curly braces, hyphens, and a URN prefix are all optional. For example, these expressions all yield the same UUID: UUID('{12345678-1234-5678-1234-567812345678}') UUID('12345678123456781234567812345678') UUID('urn:uuid:12345678-1234-5678-1234-567812345678') UUID(bytes='\x12\x34\x56\x78'*4) UUID(bytes_le='\x78\x56\x34\x12\x34\x12\x78\x56' + '\x12\x34\x56\x78\x12\x34\x56\x78') UUID(fields=(0x12345678, 0x1234, 0x5678, 0x12, 0x34, 0x567812345678)) UUID(int=0x12345678123456781234567812345678) Exactly one of 'hex', 'bytes', 'bytes_le', 'fields', or 'int' must be given.

It is a "friend" of that class, and imports data either by direct access to members of Profile class, or by reading in a dictionary that was emitted (via marshal) from the Profile class. The big change from the previous Profiler (in terms of raw functionality) is that an "add()" method has been provided to combine Stats from several distinct profile runs. Both the constructor and the add() method now take arbitrarily many file names as arguments. All the print methods now take an argument that indicates how many lines to print. If the arg is a floating point number between 0 and 1.0, then it is taken as a decimal percentage of the available lines to be printed (e.g., .1 means print 10% of all available lines). If it is an integer, it is taken to mean the number of lines of data that you wish to have printed. The sort_stats() method now processes some additional options (i.e., in addition to the old -1, 0, 1, or 2 that are respectively interpreted as 'stdname', 'calls', 'time', and 'cumulative'). It takes an arbitrary number of quoted strings to select the sort order. For example sort_stats('time', 'name') sorts on the major key of 'internal function time', and on the minor key of 'the name of the function'. Look at the two tables in sort_stats() and get_sort_arg_defs(self) for more examples. All methods return self, so you can string together commands like: Stats('foo', 'goo').strip_dirs().sort_stats('calls'). print_stats(5).print_callers(5) N)�streamc G sF |pt j| _t|�sd }n|d }|dd � }| j|� | j|� d S )Nr � )�sys�stdoutr �len�init�add)�selfr �args�arg� r � /usr/lib64/python3.6/pstats.py�__init__A s zStats.__init__c C s� d | _ g | _d | _d| _d| _d| _d| _t� | _i | _ i | _ | j |� y | j � W n8 t k r� td| jrx| jd nd | jd� � Y nX d S )Nr zInvalid timing data %sr � )�file���)� all_callees�files�fcn_list�total_tt� total_calls� prim_calls� max_name_len�set� top_level�stats� sort_arg_dict� load_stats�get_top_level_stats� Exception�printr )r r r r r r K s" z Stats.initc C s� |d kri | _ d S t|t�rxt|d��}tj|�| _ W d Q R X y"tj|�}tj |j �d | }W n Y nX |g| _ n t |d�r�|j � |j | _ i |_ | j s�td| j|f ��d S )N�rbz � create_statsz.Cannot create or construct a %r object from %r)r � isinstance�str�open�marshal�load�os�stat�timeZctime�st_mtimer �hasattrr$ � TypeError� __class__)r r �fZ file_statsr r r r ^ s( zStats.load_statsc C s� x~| j j� D ]p\}\}}}}}| j|7 _| j|7 _| j|7 _d|kr\| jj|� tt|��| j kr tt|��| _ q W d S )N�jprofiler �profiler)r2 r r3 ) r �itemsr r r r r r �func_std_stringr )r �func�cc�nc�tt�ct�callersr r r r t s zStats.get_top_level_statsc G s� |s| S x�t |�D ]�}t| �t|�kr.t|�}| j|j7 _| j|j7 _| j|j7 _| j|j7 _x|jD ]}| jj|� qvW | j |j k r�|j | _ d | _ xJ|j j � D ]<\}}|| j kr�| j | }nddddi f}t ||�| j |< q�W qW | S )Nr )�reversed�typer r r r r r r r r r r4 �add_func_stats)r �arg_list�itemr6 r+ Z old_func_statr r r r ~ s( z Stats.addc C s( t |d��}tj| j|� W dQ R X dS )z:Write the profile data to a file we know how to load back.�wbN)r' r( �dumpr )r �filenamer1 r r r � dump_stats� s zStats.dump_statsr � call count� �cumulative time� � file name� � line number� � function name�name/file/liner �primitive call count� � standard name� � internal time)�callsZncallsZcumtime� cumulativer rC �line�module�nameZnflZpcalls�stdnamer, Ztottimec C s� | j szi | _ }i }xP| jj� D ]B\}}|}x4|r`|s8P ||krJd||< P |||< |dd� }q.W q W x|D ] }||= qlW | j S )z)Expand all abbreviations that are unique.r Nr r )r �sort_arg_dict_defaultr4 )r �dictZbad_list�word�tupZfragmentr r r �get_sort_arg_defs� s zStats.get_sort_arg_defsc G s" |sd| _ | S t|�dkrFt|d t�rFd dddddddi|d g}| j� }f }d| _d}x:|D ]2}||| d }| j||| d 7 _d }qbW g }xB| jj� D ]4\}\}} } } } |j|| | | f| t |�|f � q�W |j t t |�j �d � g | _ } x |D ]}| j|d � �qW | S ) Nr r rY rT r, rR rU r z, )�keyr r )r r r% �intr^ � sort_typer r4 �appendr5 �sortr � TupleComp�compare)r ZfieldZ sort_arg_defsZ sort_tupleZ connectorr\ Z stats_listr6 r7 r8 r9 r: r; r �tupler r r � sort_stats� s2 zStats.sort_statsc C s | j r| j j� | S )N)r �reverse)r r r r � reverse_order� s zStats.reverse_orderc C s� | j }i | _ }d}x�|j� D ]�\}\}}}}} t|�} tt| ��|krTtt| ��}i } x | j� D ]\} } | | t| �< qbW | |kr�t|| ||||| f�|| < q ||||| f|| < q W | j}t� | _}x|D ]}|jt|�� q�W || _ d | _ d | _ | S )Nr ) r r4 �func_strip_pathr r5 r> r r r r r r )r ZoldstatsZnewstatsr r6 r7 r8 r9 r: r; ZnewfuncZ newcallers�func2�callerZold_topZnew_topr r r � strip_dirs� s. zStats.strip_dirsc C s| | j r d S i | _ }xb| jj� D ]T\}\}}}}}||krBi ||< x0|j� D ]$\}} ||krdi ||< | || |< qLW q W d S )N)r r r4 ) r r r6 r7 r8 r9 r: r; rk rl r r r � calc_callees s zStats.calc_calleesc C s |}t |t�rpytj|�}W n& tjk rB |d| 7 }||fS X g }x�|D ] }|jt|��rN|j|� qNW nzt|�}t |t �r�d| ko�dk n r�t || d �}|d |� }n2t |t �r�d| ko�|k n r�|}|d |� }t|�t|�k�r|dt|�t|�|f 7 }||fS )Nz# <Invalid regular expression %r> g g �?g �?r z6 List reduced from %r to %r due to restriction <%r> ) r% r& �re�compile�error�searchr5 rb r �floatr` )r Zsel�list�msgZnew_listZrexr6 �countr r r �eval_print_amount s, "" zStats.eval_print_amountc C s� | j }| jr*| jd d � }d| j d }nt| jj� �}d}x |D ]}| j|||�\}}qBW t|�}|spd|fS t|| j d� |t| j�k r�d}x(|D ] }tt |��|kr�tt |��}q�W |d |fS )Nz Ordered by: � z!

A selector supports registering file objects to be monitored for specific I/O events. A file object is a file descriptor or any object with a `fileno()` method. An arbitrary object can be attached to the file object, which can be used for example to store context information, a callback, etc. A selector can use various implementations (select(), poll(), epoll()...) depending on the platform. The default `Selector` class uses the most efficient implementation on the current platform. Nc C s t �dS )a3 Register a file object.

This module avoids a number of common traps for measuring execution times. See also Tim Peters' introduction to the Algorithms chapter in the Python Cookbook, published by O'Reilly. Library usage: see the Timer class. Command line usage: python timeit.py [-n N] [-r N] [-s S] [-t] [-c] [-p] [-h] [--] [statement] Options: -n/--number N: how many times to execute 'statement' (default: see below) -r/--repeat N: how many times to repeat the timer (default 3) -s/--setup S: statement to be executed once initially (default 'pass'). Execution time of this setup statement is NOT timed. -p/--process: use time.process_time() (default is time.perf_counter()) -t/--time: use time.time() (deprecated) -c/--clock: use time.clock() (deprecated) -v/--verbose: print raw timing results; repeat for more digits precision -u/--unit: set the output time unit (usec, msec, or sec) -h/--help: print this usage message and exit --: separate options from statement, use when statement starts with - statement: statement to be timed (default 'pass') A multi-line statement may be given by specifying each line as a separate argument; indented lines are possible by enclosing an argument in quotes and using leading spaces. Multiple -s options are treated similarly. If -n is not given, a suitable number of loops is calculated by trying successive powers of 10 until the total time is at least 0.2 seconds. Note: there is a certain baseline overhead associated with executing a pass statement. It differs between versions. The code here doesn't try to hide it, but you should be aware of it. The baseline overhead can be measured by invoking the program without arguments.

The constructor takes a statement to be timed, an additional statement used for setup, and a timer function. Both statements default to 'pass'; the timer function is platform-dependent (see module doc string). If 'globals' is specified, the code will be executed within that namespace (as opposed to inside timeit's namespace). To measure the execution time of the first statement, use the timeit() method. The repeat() method is a convenience to call timeit() multiple times and return a list of results. The statements may contain newlines, as long as they don't contain multi-line string literals. �passNc C s� || _ i }|dkrt� n|}d}t|t�rJt|td� |d }t|d�}n*t|�rl||d< |d7 }d}d}ntd ��t|t�r�t|| td� t|d �}n&t|�r�||d < |d 7 }d }ntd��t j |||d�} | | _ t| td�} t | ||� |d | _ dS )z#Constructor.

Typical use: t = Timer(...) # outside the try/except try: t.timeit(...) # or t.repeat(...) except: t.print_exc() The advantage over the standard traceback is that source lines in the compiled template will be displayed.

To be precise, this executes the setup statement once, and then returns the time it takes to execute the main statement a number of times, as a float measured in seconds. The argument is the number of times through the loop, defaulting to one million. The main statement, the setup statement and the timer function to be used are passed to the constructor.

This is a convenience function that calls the timeit() repeatedly, returning a list of results. The first argument specifies how many times to call timeit(), defaulting to 3; the second argument specifies the timer argument, defaulting to one million. Note: it's tempting to calculate mean and standard deviation from the result vector and report these. However, this is not very useful. In a typical case, the lowest value gives a lower bound for how fast your machine can run the given code snippet; higher values in the result vector are typically not caused by variability in Python's speed, but by other processes interfering with your timing accuracy. So the min() of the result is probably the only number you should be interested in. After that, you should look at the entire vector and apply common sense rather than statistics. )�ranger �append)r# r r3 �r�i�tr r r r � s z Timer.repeatc C sF x<t dd�D ].}d| }| j|�}|r0|||� |dkr P q W ||fS )a� Return the number of loops and time taken so that total time >= 0.2.

The optional 'args' argument specifies the command line to be parsed, defaulting to sys.argv[1:]. The return value is an exit code to be passed to sys.exit(); it may be None to indicate success.

'_wrap_timer' is an internal interface used for unit testing. If it is not None, it must be a callable that accepts a timer function and returns another timer function (used for unit testing).

To create a connection, call the class using these arguments: host, user, passwd, acct, timeout The first four arguments are all strings, and have default value ''. timeout must be numeric and defaults to None if not passed, meaning that no timeout will be set on any ftp socket(s) If a timeout is passed, then this is now the default timeout for all ftp socket operations for this instance. Then use self.connect() with optional host and port argument. To download a file, use ftp.retrlines('RETR ' + filename), or ftp.retrbinary() with slightly different arguments. To upload a file, use ftp.storlines() or ftp.storbinary(), which have an open file as argument (see their definitions below for details). The download/upload functions first issue appropriate TYPE and PORT or PASV commands. r � Nr zlatin-1Fc C s0 || _ || _|r,| j|� |r,| j|||� d S )N)�source_address�timeout�connect�login)�self�host�user�passwd�acctr r r r r �__init__r s z FTP.__init__c C s | S )Nr )r r r r � __enter__{ s z FTP.__enter__c G sN | j d k rJz*y | j� W n ttfk r0 Y nX W d | j d k rH| j� X d S )N)�sock�quit�OSError�EOFError�close)r �argsr r r �__exit__ s z FTP.__exit__i� c C s� |dkr|| _ |dkr || _|dkr*|| _|dk r8|| _tj| j | jf| j| jd�| _| jj| _| jj d| j d�| _ | j � | _ | j S ) aw Connect to host.

Instead of importing this module directly, import os and refer to this module as os.path. The "os.path" name is an alias for this module on Posix systems; on other systems (e.g. Mac, Windows), os.path provides the same operations in a manner specific to that platform, and is an alias to another module (e.g. macpath, ntpath). Some of this can actually be useful on non-Posix systems too, e.g. for manipulation of the pathname component of URLs. �.z..�/�:z:/bin:/usr/binNz /dev/null� )�*�normcase�isabs�join� splitdrive�split�splitext�basename�dirname� commonprefix�getsize�getmtime�getatime�getctime�islink�exists�lexists�isdir�isfile�ismount� expanduser� expandvars�normpath�abspath�samefile� sameopenfile�samestat�curdir�pardir�sep�pathsep�defpath�altsep�extsep�devnull�realpath�supports_unicode_filenames�relpath� commonpath� ALLOW_MISSINGc C s t | t�rdS dS d S )N� /r )� isinstance�bytes)�path� r1 �!/usr/lib64/python3.6/posixpath.py�_get_sep) s r3 c C s. t j| �} t| ttf�s*tdj| jj���| S )z6Normalize case of pathname.

This exports: - all functions from posix or nt, e.g. unlink, stat, etc. - os.path is either posixpath or ntpath - os.name is either 'posix' or 'nt' - os.curdir is a string representing the current directory (always '.') - os.pardir is a string representing the parent directory (always '..') - os.sep is the (or a most common) pathname separator ('/' or '\\') - os.extsep is the extension separator (always '.') - os.altsep is the alternate pathname separator (None or '/') - os.pathsep is the component separator used in $PATH etc - os.linesep is the line separator in text files ('\r' or '\n' or '\r\n') - os.defpath is the default search path for executables - os.devnull is the file path of the null device ('/dev/null', etc.) Programs that import and use 'os' stand a better chance of being portable between different platforms. Of course, they must then only use functions that are defined by all platforms (e.g., unlink and opendir), and leave all pathname manipulation to os.path (e.g., split and join). � N�altsep�curdir�pardir�sep�pathsep�linesep�defpath�name�path�devnull�SEEK_SET�SEEK_CUR�SEEK_END�fsencode�fsdecode� get_exec_path�fdopen�popen�extsepc C s | t � kS )N)�globals)r � r �/usr/lib64/python3.6/os.py�_exists% s r c C s2 y t | j�S tk r, dd� t| �D �S X d S )Nc S s g | ]}|d dkr|�qS )r �_r )�.0�nr r r � <listcomp>, s z%_get_exports_list.<locals>.<listcomp>)�list�__all__�AttributeError�dir)�moduler r r �_get_exports_list( s r" �posix� )�*)�_exitr& )�_have_functions�ntz zno os specific module foundzos.path)r r r r r r r r r' c C s" |t kr | tkr tjt | � d S )N)�_globalsr' �_set�add)�str�fnr r r �_addd s r. �HAVE_FACCESSAT�access� HAVE_FCHMODAT�chmod� HAVE_FCHOWNAT�chown� HAVE_FSTATAT�stat�HAVE_FUTIMESAT�utime� HAVE_LINKAT�link� HAVE_MKDIRAT�mkdir� HAVE_MKFIFOAT�mkfifo� HAVE_MKNODAT�mknod� HAVE_OPENAT�open�HAVE_READLINKAT�readlink� HAVE_RENAMEAT�rename�HAVE_SYMLINKAT�symlink� HAVE_UNLINKAT�unlink�rmdir�HAVE_UTIMENSAT� HAVE_FCHDIR�chdir� HAVE_FCHMOD� HAVE_FCHOWN�HAVE_FDOPENDIR�listdir� HAVE_FEXECVE�execve�HAVE_FTRUNCATE�truncate� HAVE_FUTIMENS� HAVE_FUTIMES�HAVE_FPATHCONF�pathconf�statvfs�fstatvfs� HAVE_FSTATVFS� HAVE_LCHFLAGSZchflags� HAVE_LCHMOD�lchown� HAVE_LCHOWN� HAVE_LUTIMES� HAVE_LSTATZ MS_WINDOWS� � � Fc C s� t j| �\}}|s t j|�\}}|r~|r~t j|� r~yt|||� W n tk rX Y nX t}t|t�rrttd�}||kr~dS yt| |� W n( t k r� | s�t j | � r�� Y nX dS )a� makedirs(name [, mode=0o777][, exist_ok=False]) Super-mkdir; create a leaf directory and all intermediate ones. Works like mkdir, except that any intermediate path segment (not just the rightmost) will be created if it does not exist. If the target directory already exists, raise an OSError if exist_ok is False. Otherwise no exception is raised.

Works like rmdir except that, if the leaf directory is successfully removed, directories corresponding to rightmost path segments will be pruned away until either the whole path is consumed or an error occurs.

Works like rename, except creation of any intermediate directories needed to make the new pathname good is attempted first. After the rename, directories corresponding to rightmost path segments of the old name will be pruned until either the whole path is consumed or a nonempty directory is found. Note: this function can fail with the new directory structure made if you lack permissions needed to unlink the leaf directory or file.

For each directory in the directory tree rooted at top (including top itself, but excluding '.' and '..'), yields a 3-tuple dirpath, dirnames, filenames dirpath is a string, the path to the directory. dirnames is a list of the names of the subdirectories in dirpath (excluding '.' and '..'). filenames is a list of the names of the non-directory files in dirpath. Note that the names in the lists are just names, with no path components. To get a full path (which begins with top) to a file or directory in dirpath, do os.path.join(dirpath, name). If optional arg 'topdown' is true or not specified, the triple for a directory is generated before the triples for any of its subdirectories (directories are generated top down). If topdown is false, the triple for a directory is generated after the triples for all of its subdirectories (directories are generated bottom up). When topdown is true, the caller can modify the dirnames list in-place (e.g., via del or slice assignment), and walk will only recurse into the subdirectories whose names remain in dirnames; this can be used to prune the search, or to impose a specific order of visiting. Modifying dirnames when topdown is false is ineffective, since the directories in dirnames have already been generated by the time dirnames itself is generated. No matter the value of topdown, the list of subdirectories is retrieved before the tuples for the directory and its subdirectories are generated. By default errors from the os.scandir() call are ignored. If optional arg 'onerror' is specified, it should be a function; it will be called with one argument, an OSError instance. It can report the error to continue with the walk, or raise the exception to abort the walk. Note that the filename is available as the filename attribute of the exception object. By default, os.walk does not follow symbolic links to subdirectories on systems that support them. In order to get this functionality, set the optional argument 'followlinks' to true. Caution: if you pass a relative pathname for top, don't change the current working directory between resumptions of walk. walk never changes the current directory, and assumes that the client doesn't either. Example: import os from os.path import join, getsize for root, dirs, files in os.walk('python/Lib/email'): print(root, "consumes", end="") print(sum([getsize(join(root, name)) for name in files]), end="") print("bytes in", len(files), "non-directory files") if 'CVS' in dirs: dirs.remove('CVS') # don't visit CVS directories NFT) �fspath�scandirrn �next� StopIteration�is_dir�appendr � is_symlinkr �islink�join�walk)�top�topdown�onerror� followlinks�dirs�nondirs� walk_dirs� scandir_it�error�entryr} � walk_intor r� r� �dirname�new_pathr r r r� s` : r� �.)�follow_symlinks�dir_fdc c s� t | t� st| d� r t| �} t| d|d�}t| t|d�}z:|s^tj|j �rtt j |t|��rtt || |||�E dH W dt |� X dS )a Directory tree generator. This behaves exactly like walk(), except that it yields a 4-tuple dirpath, dirnames, filenames, dirfd `dirpath`, `dirnames` and `filenames` are identical to walk() output, and `dirfd` is a file descriptor referring to the directory `dirpath`. The advantage of fwalk() over walk() is that it's safe against symlink races (when follow_symlinks is False). If dir_fd is not None, it should be a file descriptor open to a directory, and top should be relative; top will then be relative to that directory. (dir_fd is always supported for fwalk.) Caution: Since fwalk() yields file descriptors, those are only valid until the next iteration step, so you should dup() them if you want to keep them for a longer period. Example: import os for root, dirs, files, rootfd in os.fwalk('python/Lib/email'): print(root, "consumes", end="") print(sum([os.stat(name, dir_fd=rootfd).st_size for name in files]), end="") print("bytes in", len(files), "non-directory files") if 'CVS' in dirs: dirs.remove('CVS') # don't visit CVS directories � __index__F)r� r� )r� N)rl �int�hasattrry r6 rB �O_RDONLY�st�S_ISDIR�st_moder �samestat�_fwalk�close)r� r� r� r� r� �orig_st�topfdr r r �fwalk� s !r� c c s| t | �}g g }}x�|D ]�}y.tjt|| d�j�r>|j|� n |j|� W q tk r� y$tjt|| dd�j�r||j|� W n tk r� wY nX Y qX qW |r�|||| fV x�|D ]�}y t|| |d�} t|t | d�} W n8 tk �r } z|d k �r|| � w�W Y d d } ~ X nX z>|�s0t j | t| ���rRt j ||�} t | | |||�E d H W d t| � X q�W |�sx|||| fV d S )N)r� F)r� r� )rR r� r� r6 r� r~ rn �S_ISLNKrB r� r r� r� r� r� ) r� �toppathr� r� r� �namesr� r� r r� �dirfd�err�dirpathr r r r� � s< r� c G s t | |� dS )zpexecl(file, *args) Execute the executable file with argument list args, replacing the current process.

Order of methods called matters for dependency reasons. The locale language is set at the offset and then checked again before exiting. This is to make sure that the attributes were not set with a mix of information from more than one locale. This would most likely happen when using threads where one thread calls a locale-dependent function while another thread changes the locale while the function in the other thread is still running. Proper coding would call for locks to prevent changing the locale while locale-dependent code is running. The check here is done in case someone does not think about doing this. Only other possible issue is if someone changed the timezone and did not call tz.tzset . That is an issue for the programmer, though, since changing the timezone is worthless without that call. z$locale changed during initializationz&timezone changed during initializationN) r �lang�_LocaleTime__calc_weekday�_LocaleTime__calc_month�_LocaleTime__calc_am_pm�_LocaleTime__calc_timezone�_LocaleTime__calc_date_time� ValueError�time�tzname�daylight)�selfr r r �__init__4 s zLocaleTime.__init__c C s( t |�}|r|jdd� n |jd� |S )Nr � )�list�insert�append)r �seq�frontr r r Z__padS s zLocaleTime.__padc C s4 dd� t d�D �}dd� t d�D �}|| _|| _d S )Nc S s g | ]}t j| j� �qS r )�calendarZday_abbr�lower)�.0�ir r r � <listcomp>_ s z-LocaleTime.__calc_weekday.<locals>.<listcomp>� c S s g | ]}t j| j� �qS r )r!

On Unix (including Mac OSX), it starts with sys.prefix and sys.exec_prefix (if different) and appends lib/python<version>/site-packages. On other platforms (such as Windows), it tries each of the prefixes directly, as well as with lib/site-packages appended. The resulting directories, if they exist, are appended to sys.path, and also inspected for path configuration files. If a file named "pyvenv.cfg" exists one directory above sys.executable, sys.prefix and sys.exec_prefix are set to that directory and it is also checked for site-packages (sys.base_prefix and sys.base_exec_prefix will always be the "real" prefixes of the Python installation). If "pyvenv.cfg" (a bootstrap configuration file) contains the key "include-system-site-packages" set to anything other than "false" (case-insensitive), the system-level prefixes will still also be searched for site-packages; otherwise they won't. All of the resulting site-specific directories, if they exist, are appended to sys.path, and also inspected for path configuration files. A path configuration file is a file whose name has the form <package>.pth; its contents are additional directories (one per line) to be added to sys.path. Non-existing directories (or non-directories) are never added to sys.path; no directory is added to sys.path more than once. Blank lines and lines beginning with '#' are skipped. Lines starting with 'import' are executed. For example, suppose sys.prefix and sys.exec_prefix are set to /usr/local and there is a directory /usr/local/lib/python2.5/site-packages with three subdirectories, foo, bar and spam, and two path configuration files, foo.pth and bar.pth. Assume foo.pth contains the following: # foo package configuration foo bar bletch and bar.pth contains: # bar package configuration bar Then the following directories are added to sys.path, in this order: /usr/local/lib/python2.5/site-packages/bar /usr/local/lib/python2.5/site-packages/foo Note that bletch is omitted because it doesn't exist; bar precedes foo because bar.pth comes alphabetically before foo.pth; and spam is omitted because it is not mentioned in either path configuration file. The readline module is also automatically configured to enable completion for systems that support it. This can be overridden in sitecustomize, usercustomize or PYTHONSTARTUP. Starting Python in isolated mode (-I) disables automatic readline configuration.

Named constructor functions are also available, these are faster than using new(name): md5(), sha1(), sha224(), sha256(), sha384(), sha512(), blake2b(), blake2s(), sha3_224, sha3_256, sha3_384, sha3_512, shake_128, and shake_256. More algorithms may be available on your platform but the above are guaranteed to exist. See the algorithms_guaranteed and algorithms_available attributes to find out what algorithm names can be passed to new(). NOTE: If you want the adler32 or crc32 hash functions they are available in the zlib module. Choose your hash function wisely. Some have known collision weaknesses. sha384 and sha512 will be slow on 32 bit platforms. Hash objects have these methods: - update(data): Update the hash object with the bytes in data. Repeated calls are equivalent to a single call with the concatenation of all the arguments. - digest(): Return the digest of the bytes passed to the update() method so far as a bytes object. - hexdigest(): Like digest() except the digest is returned as a string of double length, containing only hexadecimal digits. - copy(): Return a copy (clone) of the hash object. This can be used to efficiently compute the digests of datas that share a common initial substring. For example, to obtain the digest of the byte string 'Nobody inspects the spammish repetition': >>> import hashlib >>> m = hashlib.md5() >>> m.update(b"Nobody inspects") >>> m.update(b" the spammish repetition") >>> m.digest() b'\xbbd\x9c\x83\xdd\x1e\xa5\xc9\xd9\xde\xc9\xa1\x8d\xf0\xff\xe9' More condensed: >>> hashlib.sha224(b"Nobody inspects the spammish repetition").hexdigest() 'a4337bc45a8fc544c03f52dc550cd6e1e87021bc896588bd79e901e2' �md5�sha1�sha224�sha256�sha384�sha512�blake2b�blake2s�sha3_224�sha3_256�sha3_384�sha3_512� shake_128� shake_256�new�algorithms_guaranteed�algorithms_available� pbkdf2_hmac� )� get_fips_modec C s dS )Nr � r r r � /usr/lib64/python3.6/hashlib.py�_hashlib_get_fips_modeI s r c C s� t }|j| �}|d k r|S �y2| dkrDdd l}|j |d< |d< �n| dkrjdd l}|j |d< |d< � n�| dkr�dd l}|j |d< |d < |j |d< |d< n�| dkr�dd l }|j |d < |d < |j |d < |d < nv| dk� r�dd l }|j |d< |j|d< nN| d k�rLdd l}|j|d< |j|d< |j|d< |j|d< |j|d< |j|d< W n tk �rd Y nX |j| �}|d k �r~|S td| ��d S ) N�SHA1r r �MD5r �SHA256r �SHA224r �SHA512r �SHA384r r r r r r r r r zunsupported hash type )r r )r r )r r r r )r r r r )r r > r r r r r r )�__builtin_constructor_cache�get�_sha1r �_md5r �_sha256r r �_sha512r r �_blake2r r �_sha3r r r r r r � ImportError� ValueError) �name�cache� constructorr r! r" r# r$ r% r r r �__get_builtin_constructorP sL r+ c C sZ t j� s| dkrt| �S y tt d| �}t j� s6|� |S ttfk rT t| �S X d S )Nr r r r Zopenssl_> r r r r )�_hashlibr r+ �getattr�AttributeErrorr' )r( �fr r r �__get_openssl_constructor{ s r0 � c K s t | �|f|�S )N)r+ )r( �data�kwargsr r r �__py_new� s r4 c K s� t j� r(| }ddddddd�j| | �} n| d kr@t| �|f|�S y:|jd d �}t j| ||d �}t j� rx| |krx|j|� |S tk r� t j� r�� t| �|�S X d S )Nzsha3-224zsha3-256zsha3-384zsha3-512Zshake128Zshake256)r r r r r r r r �usedforsecurityT)r5 > r r )r, r r r+ �popr Z _set_namer' )r( r2 r3 Z orig_namer5 Zretvalr r r � __hash_new� s, r7 N)r )�scryptz code for hash %s was not found.)r r r r r r r r r r r r r r )r r r r )r1 )r1 )�__doc__Z__always_supported�setr r �__all__r, r r r& r r+ r0 r4 r7 r Z __get_hash�unionZopenssl_md_meth_namesr r8 Z __func_name�globalsr' ZloggingZ exceptionr r r r �<module>6 s\ + ' webbrowser.cpython-36.opt-1.pyc 0000644 00000036626 15246273046 0012340 0 ustar 00 3 \U � @ s� d Z ddlZddlZddlZddlZddlZddddddgZG d d� de�Zi Z g Z dOd d�Z dPd d�Z dQdd�Z dd� Zdd� ZdRdd�ZG dd� de�ZG dd� de�ZG dd� de�ZG dd� de�ZG dd � d e�ZG d d � d e�ZG d d � d e�ZG d!d"� d"e�ZeZG d#d$� d$e�ZG d%d&� d&e�Z G d'd(� d(e�Z G d)d*� d*e�Z d+d,� Z ej j d-��rle � ej j d.��rej!d/��r�e d/ded/�� ej!d0��r�e d0ded0�� ej!d1��r�e d1de d1�� ej!d2��r�e d2ded2�� ej!d3��re d3ded3�� ej"dd4� d5k�r�G d6d7� d7e�Z#g Z i Z e d8e#� ej$j%ej j d9d:�d;�Z&x8d<d=d>d?d@dAe&fD ]"Z'ej!e'��rhe e'dee'�� �qhW ej"dBk�rG dCdD� dDe�Z(G dEdF� dFe�Z)e dGde)dG�dS� e d<de)d<�dT� e dHde)dH�dU� e dDde)dI�dV� dJej k�rtej dJ j*ej+�Z,e,j-� xBe,D ]:Z.e.dKk�r.ee.dW�Z/e/d dk�r.e e.dee.�dX� �q.W dZ.[.[,dLdM� Z0e1dNk�r�e0� dS )Yz?Interfaces for launching and remotely controlling Web browsers.� N�Error�open�open_new� open_new_tab�get�registerc @ s e Zd ZdS )r N)�__name__� __module__� __qualname__� r r �"/usr/lib64/python3.6/webbrowser.pyr s � c C s< ||gt | j� < |dkr$tj| � n|dk r8tjd| � dS )z9Register a browser connector and, optionally, connection.r N)� _browsers�lower� _tryorder�append�insert)�name�klass�instance�update_tryorderr r r r s c C s� | dk r| g}nt }x�|D ]�}d|krVtj|�}|d dkrLt|dd� �S t|�S qyt|j� }W n tk r� t|�}Y nX |d dk r�|d S |d dk r|d � S qW t d��dS ) zCReturn a browser launcher instance appropriate for the environment.Nz%sr �&r z!could not locate runnable browser���r ) r �shlex�split�BackgroundBrowser�GenericBrowserr r �KeyError� _synthesizer )ZusingZ alternatives�browser�commandr r r r s$ Tc C s, x&t D ] }t|�}|j| ||�rdS qW dS )NTF)r r r )�url�new� autoraiser r r r r r 9 s c C s t | d�S )Nr )r )r! r r r r @ s c C s t | d�S )N� )r )r! r r r r C s c C s� | j � d }tj|�s ddgS tjj|�}yt|j� }W n tk rR ddgS X |d }|r�|j� |jkr�ddl }|j |�}| |_ tjj| �|_t | d||� d|gS ddgS )a� Attempt to synthesize a controller base on existing controllers.

Args: address: A string or integer representing the IP [& network]. '192.0.2.0/24' '192.0.2.0/255.255.255.0' '192.0.0.2/0.0.0.255' are all functionally the same in IPv4. Similarly, '192.0.2.1' '192.0.2.1/255.255.255.255' '192.0.2.1/32' are also functionally equivalent. That is to say, failing to provide a subnetmask will create an object with a mask of /32. If the mask (portion after the / in the argument) is given in dotted quad form, it is treated as a netmask if it starts with a non-zero field (e.g. /255.0.0.0 == /8) and as a hostmask if it starts with a zero field (e.g. 0.255.255.255 == /8), with the single exception of an all-zero mask which is treated as a netmask == /0. If no mask is given, a default of /32 is used. Additionally, an integer can be passed, so IPv4Network('192.0.2.1') == IPv4Network(3221225985) or, more generally IPv4Interface(int(IPv4Interface('192.0.2.1'))) == IPv4Interface('192.0.2.1') Raises: AddressValueError: If ipaddress isn't a valid IPv4 address.

This module provides two interfaces, broadly similar to the builtin function compile(), which take program text, a filename and a 'mode' and: - Return code object if the command is complete and valid - Return None if the command is incomplete - Raise SyntaxError, ValueError or OverflowError if the command is a syntax error (OverflowError and ValueError can be produced by malformed literals). Approach: First, check if the source consists entirely of blank lines and comments; if so, replace it with 'pass', because the built-in parser doesn't always do the right thing for these. Compile three times: as is, with \n, and with \n\n appended. If it compiles as is, it's complete. If it compiles with one \n appended, we expect more. If it doesn't compile either way, we compare the error we get when compiling with \n or \n\n appended. If the errors are the same, the code is broken. But if the errors are different, we expect more. Not intuitive; not even guaranteed to hold in future releases; but this matches the compiler's behavior from Python 1.4 through 2.2, at least. Caveat: It is possible (but not likely) that the parser stops parsing with a successful outcome before reaching the end of the source; in this case, trailing symbols may be ignored instead of causing an error. For example, a backslash followed by two newlines may be followed by arbitrary garbage. This will be fixed once the API for the parser is better. The two interfaces are: compile_command(source, filename, symbol): Compiles a single command in the manner described above. CommandCompiler(): Instances of this class have __call__ methods identical in signature to compile_command; the difference is that if the instance compiles program text containing a __future__ statement, the instance 'remembers' and compiles all subsequent program texts with the statement in force. The module also provides another class: Compile(): Instances of this class act like the built-in function compile, but with 'memory' in the sense described above. � Nc C s g | ]}t t|��qS � )�getattr� __future__)�.0Zfnamer r � /usr/lib64/python3.6/codeop.py� <listcomp>= s r �compile_command�Compile�CommandCompileri c - C s* x8|j d�D ] }|j� }|r |d dkr P q W |dkr:d}d } }}d } } } y| |||�}W n" tk r� } zW Y d d }~X nX y| |d ||�} W n& tk r� } z | }W Y d d } ~ X nX y| |d ||�} W n& tk r� } z | }W Y d d } ~ X nX |�r|S | �r&t|�t|�k�r&|�d S )N� r �#�eval�passz )�split�strip� SyntaxError�repr) �compiler�source�filename�symbol�line�errZerr1Zerr2�code�code1�code2�er r r �_maybe_compileD s0 r c C s t | ||t�S )N)�compile�PyCF_DONT_IMPLY_DEDENT)r r r r r r �_compilee s r �<input>�singlec C s t t| ||�S )as Compile a command and determine whether it is incomplete.

Returns a new list containing elements from the population while leaving the original population unchanged. The resulting list is in selection order so that all sub-slices will also be valid random samples. This allows raffle winners (the sample) to be partitioned into grand prize and second place winners (the subslices). Members of the population need not be hashable or unique. If the population contains repeats, then each occurrence is a possible selection in the sample. To choose a sample in a range of integers, use range as an argument.

In simplest use, end each module M to be tested with: def _test(): import doctest doctest.testmod() if __name__ == "__main__": _test() Then running the module as a script will cause the examples in the docstrings to get executed and verified: python M.py This won't display anything unless an example fails, in which case the failing example(s) and the cause(s) of the failure(s) are printed to stdout (why not stderr? because stderr is a lame hack <0.2 wink>), and the final line of output is "Test failed.". Run it with the -v switch instead: python M.py -v and a detailed report of all examples tried is printed to stdout, along with assorted summaries at the end. You can force verbose mode by passing "verbose=True" to testmod, or prohibit it by passing "verbose=False". In either of those cases, sys.argv is not examined by testmod. There are a variety of other ways to run doctests, including integration with the unittest framework, and support for running non-Python text files containing doctests. There are also many ways to override parts of doctest's default behaviors.

The constructor adds a newline if needed. - want: The expected output from running the source code (either from stdout, or a traceback in case of exception). `want` ends with a newline unless it's empty, in which case it's an empty string. The constructor adds a newline if needed. - exc_msg: The exception message generated by the example, if the example is expected to generate an exception; or `None` if it is not expected to generate an exception. This exception message is compared against the return value of `traceback.format_exception_only()`. `exc_msg` ends with a newline unless it's `None`. The constructor adds a newline if needed. - lineno: The line number within the DocTest string containing this Example where the Example begins. This line number is zero-based, with respect to the beginning of the DocTest. - indent: The example's indentation in the DocTest string. I.e., the number of space characters that precede the example's first prompt. - options: A dictionary mapping from option flags to True or False, which is used to override default options for this example. Any option flags not contained in this dictionary are left at their default value (as specified by the DocTestRunner's optionflags). By default, no options are set.

The optional parameter `module` is the module that contains the given object. If the module is not specified or is None, then the test finder will attempt to automatically determine the correct module. The object's module is used: - As a default namespace, if `globs` is not specified. - To prevent the DocTestFinder from extracting DocTests from objects that are imported from other modules. - To find the name of the file containing the object. - To help find the line number of the object within its file. Contained objects whose module does not match `module` are ignored. If `module` is False, no attempt to find the module will be made. This is obscure, of use mostly in tests: if `module` is False, or is None but cannot be found automatically, then all objects are considered to belong to the (non-existent) module, so all contained objects will (recursively) be searched for doctests. The globals for each DocTest is formed by combining `globs` and `extraglobs` (bindings in `extraglobs` override bindings in `globs`). A new copy of the globals dictionary is created for each DocTest.

The `run` method is used to process a single DocTest case. It returns a tuple `(f, t)`, where `t` is the number of test cases tried, and `f` is the number of test cases that failed. >>> tests = DocTestFinder().find(_TestClass) >>> runner = DocTestRunner(verbose=False) >>> tests.sort(key = lambda test: test.name) >>> for test in tests: ... print(test.name, '->', runner.run(test)) _TestClass -> TestResults(failed=0, attempted=2) _TestClass.__init__ -> TestResults(failed=0, attempted=2) _TestClass.get -> TestResults(failed=0, attempted=2) _TestClass.square -> TestResults(failed=0, attempted=1) The `summarize` method prints a summary of all the test cases that have been run by the runner, and returns an aggregated `(f, t)` tuple: >>> runner.summarize(verbose=1) 4 items passed all tests: 2 tests in _TestClass 2 tests in _TestClass.__init__ 2 tests in _TestClass.get 1 tests in _TestClass.square 7 tests in 4 items. 7 passed and 0 failed. Test passed. TestResults(failed=0, attempted=7) The aggregated number of tried examples and failed examples is also available via the `tries` and `failures` attributes: >>> runner.tries 7 >>> runner.failures 0 The comparison between expected outputs and actual outputs is done by an `OutputChecker`. This comparison may be customized with a number of option flags; see the documentation for `testmod` for more information. If the option flags are insufficient, then the comparison may also be customized by passing a subclass of `OutputChecker` to the constructor. The test runner's display output can be controlled in two ways. First, an output function (`out) can be passed to `TestRunner.run`; this function will be called with strings that should be displayed. It defaults to `sys.stdout.write`. If capturing the output is not sufficient, then the display output can be also customized by subclassing DocTestRunner, and overriding the methods `report_start`, `report_success`, `report_unexpected_exception`, and `report_failure`. r4 �F Nr" c C sN |pt � | _|dkr dtjk}|| _|| _|| _d| _d| _i | _ t � | _ dS )ac Create a new test runner.

Also test examples reachable from dict m.__test__ if it exists and is not None. m.__test__ maps names to functions, classes and strings; function and class docstrings are tested even if the name is private; strings are tested directly, as if they were docstrings. Return (#failures, #tests). See help(doctest) for an overview. Optional keyword arg "name" gives the name of the module; by default use m.__name__. Optional keyword arg "globs" gives a dict to be used as the globals when executing examples; by default, use m.__dict__. A copy of this dict is actually used for each docstring, so that each docstring's examples start with a clean slate. Optional keyword arg "extraglobs" gives a dictionary that should be merged into the globals that are used to execute examples. By default, no extra globals are used. This is new in 2.4. Optional keyword arg "verbose" prints lots of stuff if true, prints only failures if false; by default, it's true iff "-v" is in sys.argv. Optional keyword arg "report" prints a summary at the end when true, else prints nothing at the end. In verbose mode, the summary is detailed, else very brief (in fact, empty if all tests passed). Optional keyword arg "optionflags" or's together module constants, and defaults to 0. This is new in 2.3.

Optional keyword arg "module_relative" specifies how filenames should be interpreted: - If "module_relative" is True (the default), then "filename" specifies a module-relative path. By default, this path is relative to the calling module's directory; but if the "package" argument is specified, then it is relative to that package. To ensure os-independence, "filename" should use "/" characters to separate path segments, and should not be an absolute path (i.e., it may not begin with "/"). - If "module_relative" is False, then "filename" specifies an os-specific path. The path may be absolute or relative (to the current working directory). Optional keyword arg "name" gives the name of the test; by default use the file's basename. Optional keyword argument "package" is a Python package or the name of a Python package whose directory should be used as the base directory for a module relative filename. If no package is specified, then the calling module's directory is used as the base directory for module relative filenames. It is an error to specify "package" if "module_relative" is False. Optional keyword arg "globs" gives a dict to be used as the globals when executing examples; by default, use {}. A copy of this dict is actually used for each docstring, so that each docstring's examples start with a clean slate. Optional keyword arg "extraglobs" gives a dictionary that should be merged into the globals that are used to execute examples. By default, no extra globals are used.

The test code is run in such a way that errors are not caught. This way a caller can catch the errors and initiate post-mortem debugging. The DocTestCase provides a debug method that raises UnexpectedException errors if there is an unexpected exception: >>> test = DocTestParser().get_doctest('>>> raise KeyError\n42', ... {}, 'foo', 'foo.py', 0) >>> case = DocTestCase(test) >>> try: ... case.debug() ... except UnexpectedException as f: ... failure = f The UnexpectedException contains the test, the example, and the original exception: >>> failure.test is test True >>> failure.example.want '42\n' >>> exc_info = failure.exc_info >>> raise exc_info[1] # Already has the traceback Traceback (most recent call last): ... KeyError If the output doesn't match, then a DocTestFailure is raised: >>> test = DocTestParser().get_doctest(''' ... >>> x = 1 ... >>> x ... 2 ... ''', {}, 'foo', 'foo.py', 0) >>> case = DocTestCase(test) >>> try: ... case.debug() ... except DocTestFailure as f: ... failure = f DocTestFailure objects provide access to the test: >>> failure.test is test True As well as to the example: >>> failure.example.want '2\n' and the actual output: >>> failure.got '1\n' F)r r r� )r> N)rd r r_ r` r? ra re )rf rV r+ r+ r, r! � s B zDocTestCase.debugc C s | j jS )N)ra r* )rf r+ r+ r, r� � s zDocTestCase.idc C sP t | �t |�k rtS | j|jkoN| j|jkoN| j|jkoN| j|jkoN| j|jkS )N)r� r� ra r_ rb rc r` )rf r� r+ r+ r, r� � s zDocTestCase.__eq__c C s t | j| j| j| jf�S )N)r� r_ rb rc r` )rf r+ r+ r, r� � s zDocTestCase.__hash__c C s, | j jjd�}d|d dj|d d� �f S )Nr} z%s (%s)r& rm rm )ra r* ro r� )rf r* r+ r+ r, r� � s zDocTestCase.__repr__c C s d| j j S )Nz Doctest: )ra r* )rf r+ r+ r, �shortDescription s z DocTestCase.shortDescription)r" NNN)r5 rk rl r� rd re rh rf r! r� r� r� r� rP rj r+ r+ r+ r, r\ g s H r\ c @ s0 e Zd Zdd� Zdd� Zdd� Zdd� ZeZd S ) �SkipDocTestCasec C s || _ tj| d � d S )N)rB r\ r� )rf rB r+ r+ r, r� s zSkipDocTestCase.__init__c C s | j d� d S )Nz-DocTestSuite will not work with -O2 and above)ZskipTest)rf r+ r+ r, rd s zSkipDocTestCase.setUpc C s d S )Nr+ )rf r+ r+ r, � test_skip s zSkipDocTestCase.test_skipc C s d| j j S )NzSkipping tests from %s)rB r5 )rf r+ r+ r, rj s z SkipDocTestCase.shortDescriptionN)r5 rk rl r� rd rl rj rP r+ r+ r+ r, rk s rk c @ s e Zd Zdd� ZdS )� _DocTestSuitec C s d S )Nr+ )rf �indexr+ r+ r, �_removeTestAtIndex s z _DocTestSuite._removeTestAtIndexN)r5 rk rl ro r+ r+ r+ r, rm s rm c K s� |dkrt � }t| �} |j| ||d�}| rPtjjdkrPt� }|jt| �� |S |j � t� }x\|D ]T}t |j �dkrxqd|j s�| j }|dd� dkr�|dd � }||_ |jt|f|�� qdW |S ) a Convert doctest tests for a module to a unittest test suite. This converts each documentation string in a module that contains doctest tests to a unittest test case. If any of the tests in a doc string fail, then the test case fails. An exception is raised showing the name of the file containing the test and a (sometimes approximate) line number. The `module` argument provides the module to be tested. The argument can be either a module or a module name. If no argument is given, the calling module is used. A number of options may be provided as keyword arguments: setUp A set-up function. This is called before running the tests in each file. The setUp function will be passed a DocTest object. The setUp function can access the test globals as the globs attribute of the test passed. tearDown A tear-down function. This is called after running the tests in each file. The tearDown function will be passed a DocTest object. The tearDown function can access the test globals as the globs attribute of the test passed. globs A dictionary containing initial global variables for the tests. optionflags A set of doctest option flags expressed as an integer.

The path to each doctest file is given as a string; the interpretation of that string depends on the keyword argument "module_relative". A number of options may be provided as keyword arguments: module_relative If "module_relative" is True, then the given file paths are interpreted as os-independent module-relative paths. By default, these paths are relative to the calling module's directory; but if the "package" argument is specified, then they are relative to that package. To ensure os-independence, "filename" should use "/" characters to separate path segments, and may not be an absolute path (i.e., it may not begin with "/"). If "module_relative" is False, then the given file paths are interpreted as os-specific paths. These paths may be absolute or relative (to the current working directory). package A Python package or the name of a Python package whose directory should be used as the base directory for module relative paths. If "package" is not specified, then the calling module's directory is used as the base directory for module relative filenames. It is an error to specify "package" if "module_relative" is False. setUp A set-up function. This is called before running the tests in each file. The setUp function will be passed a DocTest object. The setUp function can access the test globals as the globs attribute of the test passed. tearDown A tear-down function. This is called after running the tests in each file. The tearDown function will be passed a DocTest object. The tearDown function can access the test globals as the globs attribute of the test passed. globs A dictionary containing initial global variables for the tests. optionflags A set of doctest option flags expressed as an integer. parser A DocTestParser (or subclass) that should be used to extract tests from the files. encoding An encoding that will be used to convert the files to unicode. rS TrR )rm r. rC rq ru )�paths�kwrr r� r+ r+ r, r � s 8 c C s� g }x�t � j| �D ]x}t|t�rj|j|jdd � � |j}|r�|jd� |dd� |jd�dd � D �7 }q|dd� |jd�dd � D �7 }qW x |r�|d dkr�|j� q�W x |r�|d dkr�|jd � q�W dj |�d S )aw Extract script from text with examples.

As the example above shows, the add_argument() method is used to populate the parser with actions for optional and positional arguments. Then the parse_args() method is invoked to convert the args at the command-line into an object with attributes. - ArgumentError -- The exception raised by ArgumentParser objects when there are errors with the parser's actions. Errors raised while parsing the command-line are caught by ArgumentParser and emitted as command-line messages. - FileType -- A factory for defining types of files to be created. As the example above shows, instances of FileType are typically passed as the type= argument of add_argument() calls. - Action -- The base class for parser actions. Typically actions are selected by passing strings like 'store_true' or 'append_const' to the action= argument of add_argument(). However, for greater customization of ArgumentParser actions, subclasses of Action may be defined and passed as the action= argument. - HelpFormatter, RawDescriptionHelpFormatter, RawTextHelpFormatter, ArgumentDefaultsHelpFormatter -- Formatter classes which may be passed as the formatter_class= argument to the ArgumentParser constructor. HelpFormatter is the default, RawDescriptionHelpFormatter and RawTextHelpFormatter tell the parser not to change the formatting for help text, and ArgumentDefaultsHelpFormatter adds information about argument defaults to the help. All other classes in this module are considered implementation details. (Also note that HelpFormatter and RawDescriptionHelpFormatter are only considered public as object names -- the API of the formatter objects is still considered an implementation detail.) z1.1�ArgumentParser� ArgumentError�ArgumentTypeError�FileType� HelpFormatter� ArgumentDefaultsHelpFormatter�RawDescriptionHelpFormatter�RawTextHelpFormatter�MetavarTypeHelpFormatter� Namespace�Action� ONE_OR_MORE�OPTIONAL�PARSER� REMAINDER�SUPPRESS� ZERO_OR_MORE� N)�gettext�ngettextz ==SUPPRESS==�?�*�+zA...z...Z_unrecognized_argsc @ s( e Zd ZdZdd� Zdd� Zdd� ZdS ) �_AttributeHoldera Abstract base class that provides __repr__.

Action objects are used by an ArgumentParser to represent the information needed to parse a single argument from one or more strings from the command line. The keyword arguments to the Action constructor are also all attributes of Action instances. Keyword Arguments: - option_strings -- A list of command-line option strings which should be associated with this action. - dest -- The name of the attribute to hold the created object(s) - nargs -- The number of command-line arguments that should be consumed. By default, one argument will be consumed and a single value will be produced. Other values include: - N (an integer) consumes N arguments (and produces a list) - '?' consumes zero or one arguments - '*' consumes zero or more arguments (and produces a list) - '+' consumes one or more arguments (and produces a list) Note that the difference between the default and nargs=1 is that with the default, a single value will be produced, while with nargs=1, a list containing a single value will be produced. - const -- The value to be produced if the option is specified and the option uses an action that takes no values. - default -- The value to be produced if the option is not specified. - type -- A callable that accepts a single string argument, and returns the converted value. The standard Python types str, int, float, and complex are useful examples of such callables. If None, str is used. - choices -- A container of values that should be allowed. If not None, after a command-line argument has been converted to the appropriate type, an exception will be raised if it is not a member of this collection. - required -- True if the action must always be specified at the command line. This is only meaningful for optional command-line arguments. - help -- The help string describing the argument. - metavar -- The name to be used for the option's argument with the help string. If None, the 'dest' value will be used as the name.

PurePath represents a filesystem path and offers operations which don't imply any actual filesystem I/O.

This module provides functions for calculating statistics of data, including averages, variance, and standard deviation. Calculating averages -------------------- ================== ============================================= Function Description ================== ============================================= mean Arithmetic mean (average) of data. harmonic_mean Harmonic mean of data. median Median (middle value) of data. median_low Low median of data. median_high High median of data. median_grouped Median, or 50th percentile, of grouped data. mode Mode (most common value) of data. ================== ============================================= Calculate the arithmetic mean ("the average") of data: >>> mean([-1.0, 2.5, 3.25, 5.75]) 2.625 Calculate the standard median of discrete data: >>> median([2, 3, 4, 5]) 3.5 Calculate the median, or 50th percentile, of data grouped into class intervals centred on the data values provided. E.g. if your data points are rounded to the nearest whole number: >>> median_grouped([2, 2, 3, 3, 3, 4]) #doctest: +ELLIPSIS 2.8333333333... This should be interpreted in this way: you have two data points in the class interval 1.5-2.5, three data points in the class interval 2.5-3.5, and one in the class interval 3.5-4.5. The median of these data points is 2.8333... Calculating variability or spread --------------------------------- ================== ============================================= Function Description ================== ============================================= pvariance Population variance of data. variance Sample variance of data. pstdev Population standard deviation of data. stdev Sample standard deviation of data. ================== ============================================= Calculate the standard deviation of sample data: >>> stdev([2.5, 3.25, 5.5, 11.25, 11.75]) #doctest: +ELLIPSIS 4.38961843444... If you have previously calculated the mean, you can pass it as the optional second argument to the four "spread" functions to avoid recalculating it: >>> data = [1, 2, 2, 4, 4, 4, 5, 6] >>> mu = mean(data) >>> pvariance(data, mu) 2.5 Exceptions ---------- A single exception is defined: StatisticsError is a subclass of ValueError. �StatisticsError�pstdev� pvariance�stdev�variance�median� median_low� median_high�median_grouped�mean�mode� harmonic_mean� N)�Fraction)�Decimal)�groupby�chain)� bisect_left� bisect_rightc @ s e Zd ZdS )r N)�__name__� __module__� __qualname__� r r �"/usr/lib64/python3.6/statistics.pyr c s c C s� d}t |�\}}||i}|j}ttt|��}xRt| t�D ]D\}} t||�}x0tt | �D ]"\}}|d7 }||d�| ||< qVW q8W d|kr�|d } ntdd� t|j � �D ��} || |fS )aC _sum(data [, start]) -> (type, sum, count) Return a high-precision sum of the given numeric data as a fraction, together with the type to be converted to and the count of items. If optional argument ``start`` is given, it is added to the total. If ``data`` is empty, ``start`` (defaulting to 0) is returned. Examples -------- >>> _sum([3, 2.25, 4.5, -0.5, 1.0], 0.75) (<class 'float'>, Fraction(11, 1), 5) Some sources of round-off error will be avoided: # Built-in sum returns zero. >>> _sum([1e50, 1, -1e50] * 1000) (<class 'float'>, Fraction(1000, 1), 3000) Fractions and Decimals are also supported: >>> from fractions import Fraction as F >>> _sum([F(2, 3), F(7, 5), F(1, 4), F(5, 6)]) (<class 'fractions.Fraction'>, Fraction(63, 20), 4) >>> from decimal import Decimal as D >>> data = [D("0.1375"), D("0.2108"), D("0.3061"), D("0.0419")] >>> _sum(data) (<class 'decimal.Decimal'>, Fraction(6963, 10000), 4) Mixed types are currently treated as an error, except that int is allowed. r � Nc s s | ]\}}t ||�V qd S )N)r )�.0�d�nr r r � <genexpr>� s z_sum.<locals>.<genexpr>) � _exact_ratio�get�_coerce�int�typer �map�sum�sorted�items) �data�start�countr r ZpartialsZ partials_get�T�typ�values�totalr r r �_sumi s $ r. c C s( y| j � S tk r" tj| �S X d S )N)Z is_finite�AttributeError�mathZisfinite)�xr r r � _isfinite� s r2 c C s� | |kr | S |t ks |tkr | S | t kr,|S t|| �r:|S t| |�rH| S t| t �rV|S t|t �rd| S t| t�r|t|t�r||S t| t�r�t|t�r�| S d}t|| j|jf ��dS )z�Coerce types T and S to a common type, or raise TypeError.

The harmonic mean, sometimes called the subcontrary mean, is the reciprocal of the arithmetic mean of the reciprocals of the data, and is often appropriate when averaging quantities which are rates or ratios, for example speeds. Example: Suppose an investor purchases an equal value of shares in each of three companies, with P/E (price/earning) ratios of 2.5, 3 and 10. What is the average P/E ratio for the investor's portfolio? >>> harmonic_mean([2.5, 3, 10]) # For an equal investment portfolio. 3.6 Using the arithmetic mean would give an average of about 5.167, which is too high.

In the above example, the values 1, 2, 3, etc. actually represent the midpoint of classes 0.5-1.5, 1.5-2.5, 2.5-3.5, etc. The middle value falls somewhere in class 3.5-4.5, and interpolation is used to estimate it. Optional argument ``interval`` represents the class interval, and defaults to 1. Changing the class interval naturally will change the interpolated 50th percentile value: >>> median_grouped([1, 3, 3, 5, 7], interval=1) 3.25 >>> median_grouped([1, 3, 3, 5, 7], interval=2) 3.5 This function does not check whether the data points are at least ``interval`` apart. r zno median for empty datar rV zexpected number but got %r) r% rF r rS �str�bytesr6 r5 rK rN ) r' Zintervalr r1 �obj�L�l1�l2Zcf�fr r r r � s& c C sB t | �}t|�dkr |d d S |r6tdt|� ��ntd��dS )a� Return the most common data point from discrete or nominal data. ``mode`` assumes discrete data, and returns a single value.

SMTP Objects: SMTP objects have the following attributes: helo_resp This is the message given by the server in response to the most recent HELO command. ehlo_resp This is the message given by the server in response to the most recent EHLO command. This is usually multiline. does_esmtp This is a True value _after you do an EHLO command_, if the server supports ESMTP. esmtp_features This is a dictionary, which, if the server supports ESMTP, will _after you do an EHLO command_, contain the names of the SMTP service extensions this server supports, and their parameters (if any). Note, all extension names are mapped to lower case in the dictionary. See each method's docstrings for details. In general, there is a method of the same name to perform each SMTP command. There is also a method called 'sendmail' that will do an entire mail transaction. r N�ehlor c C s� || _ || _i | _d| _|| _|rL| j||�\}}|dkrL| j� t||��|dk r\|| _nPt j � }d|krt|| _n8d} yt j t j � �} W n t j k r� Y nX d| | _dS )a Initialize a new instance. If specified, `host' is the name of the remote host to which to connect. If specified, `port' specifies the port to which to connect. By default, smtplib.SMTP_PORT is used. If a host is specified the connect method is called, and if it returns anything other than a success code an SMTPConnectError is raised. If specified, `local_hostname` is used as the FQDN of the local host in the HELO/EHLO command. Otherwise, the local hostname is found using socket.getfqdn(). The `source_address` parameter takes a 2-tuple (host, port) for the socket to bind to as its source address before connecting. If the host is '' and port is 0, the OS default behavior will be used. �ascii�� N�.z 127.0.0.1z[%s])�_host�timeout�esmtp_features�command_encoding�source_address�connect�closer �local_hostname�socketZgetfqdnZ gethostbynameZ gethostnameZgaierror) r �host�portr< r6 r9 r r Zfqdnr) r r r r � s* z SMTP.__init__c C s | S )Nr )r r r r � __enter__ s zSMTP.__enter__c G sN z>y$| j d�\}}|dkr$t||��W n tk r: Y nX W d | j� X d S )NZQUIT�� )�docmdr r r; )r r r �messager r r �__exit__ s z SMTP.__exit__c C s || _ dS )z�Set the debug output level.

This method may raise the following exceptions: SMTPHeloError The server didn't reply properly to the helo greeting. �starttlsz+STARTTLS extension not supported by server.ZSTARTTLSr3 z&No SSL support included in this PythonNz4context and keyfile arguments are mutually exclusivez5context and certfile arguments are mutually exclusiver zAkeyfile and certfile are deprecated, use a custom context insteadr� )�certfile�keyfile)�server_hostname)r� r� r rB � _have_ssl� RuntimeErrorrU �warnings�warn�DeprecationWarning�ssl�_create_stdlib_context� wrap_socketrX r5 rH ru r} r7 r~ r )r r� r� �contextrp Zreplyr� r r r r� � s8 z SMTP.starttlsc C sf | j � g }t|t�r$t|�jd�}| jr^| jd�rF|jdt|� � x|D ]}|j|� qLW | j ||�\}} |dkr�|dkr�| j � n| j � t || |��i } t|t�r�|g}xP|D ]H} | j | |�\}} |dkr�|dkr�|| f| | < |dkr�| j � t| ��q�W t| �t|�k�r$| j � t| ��| j|�\}} |dk�rb|dk�rP| j � n| j � t|| ��| S )a| This command performs an entire mail transaction. The arguments are: - from_addr : The address sending this mail. - to_addrs : A list of addresses to send this mail to. A bare string will be treated as a list with 1 address. - msg : The message to send. - mail_options : List of ESMTP options (such as 8bitmime) for the mail command. - rcpt_options : List of ESMTP options (such as DSN commands) for all the rcpt commands. msg may be a string containing characters in the ASCII range, or a byte string. A string is encoded to bytes using the ascii codec, and lone \r and \n characters are converted to \r\n characters. If there has been no previous EHLO or HELO command this session, this method tries ESMTP EHLO first. If the server does ESMTP, message size and each of the specified options will be passed to it. If EHLO fails, HELO will be tried and ESMTP options suppressed. This method will return normally if the mail is accepted for at least one recipient. It returns a dictionary, with one entry for each recipient that was refused. Each entry contains a tuple of the SMTP error code and the accompanying error message sent by the server. This method may raise the following exceptions: SMTPHeloError The server didn't reply properly to the helo greeting. SMTPRecipientsRefused The server rejected ALL recipients (no mail was sent). SMTPSenderRefused The server didn't accept the from_addr. SMTPDataError The server replied with an unexpected error code (other than a refusal of a recipient). SMTPNotSupportedError The mail_options parameter includes 'SMTPUTF8' but the SMTPUTF8 extension is not supported by the server. Note: the connection will be open even after an exception is raised. Example: >>> import smtplib >>> s=smtplib.SMTP("localhost") >>> tolist=["one@one.org","two@two.org","three@three.org","four@four.org"] >>> msg = '''\ ... From: Me@my.org ... Subject: testin'... ... ... This is a test ''' >>> s.sendmail("me@my.org",tolist,msg) { "three@three.org" : ( 550 ,"User unknown" ) } >>> s.quit() In the above example, the message was accepted for delivery to three of the four addresses, and one was rejected, with the error code 550. If all addresses are accepted, then the method will return an empty dictionary. r2 �sizezsize=%drw i� � )r� r] r^ r0 r_ r~ r� rn rm r� r; r� r r� r r. r ) r � from_addr�to_addrsr � mail_options� rcpt_optionsZ esmtp_optsZoptionr rp Zsenderrsr� r r r �sendmail sF @ z SMTP.sendmailc C s� | j � |jd�}|dkr d}nt|�dkr2d}ntd��|dkr||d |krZ||d n ||d }tjj|g�d d }|dkr�d d � ||d ||d ||d fD �}dd � tjj|�D �}tj|�} | d = | d= d} ydj|f|��j d� W n. t k �r( | j d��s t d��d} Y nX t j� �R} | �r^tjj| |jjdd�d�} |d �}n tjj| �} | j| dd� | j� } W dQ R X | j||| ||�S ) a~ Converts message to a bytestring and passes it to sendmail. The arguments are as for sendmail, except that msg is an email.message.Message object. If from_addr is None or to_addrs is None, these arguments are taken from the headers of the Message as described in RFC 2822 (a ValueError is raised if there is more than one set of 'Resent-' headers). Regardless of the values of from_addr and to_addr, any Bcc field (or Resent-Bcc field, when the Message is a resent) of the Message object won't be transmitted. The Message object is then serialized using email.generator.BytesGenerator and sendmail is called to transmit the message. If the sender or any of the recipient addresses contain non-ASCII and the server advertises the SMTPUTF8 capability, the policy is cloned with utf8 set to True for the serialization, and SMTPUTF8 and BODY=8BITMIME are asserted on the send. If the server does not support SMTPUTF8, an SMTPNotSupported error is raised. Otherwise the generator is called without modifying the policy. z Resent-DateNr rG zResent-z0message has more than one 'Resent-' header blockZSender�Fromr c S s g | ]}|d k r|�qS )Nr )r� �fr r r r� � s z%SMTP.send_message.<locals>.<listcomp>�ToZBccZCcc S s g | ] }|d �qS )rG r )r� �ar r r r� � s z Resent-BccFr2 r� z�One or more source or delivery addresses require internationalized email support, but the server does not advertise the required SMTPUTF8 capabilityT)�utf8)�policy�SMTPUTF8� BODY=8BITMIMEz )�linesep)r� r� )r� Zget_allrm rU r" r# Z getaddresses�copyro r_ �UnicodeEncodeErrorr� r �io�BytesIO� generatorZBytesGeneratorr� ZcloneZflatten�getvaluer� )r r r� r� r� r� ZresentZ header_prefixZ addr_fieldsZmsg_copyZ internationalZbytesmsg�gZflatmsgr r r � send_message| sJ zSMTP.send_messagec C s< z | j }d| _ |r|j� W d| j}d| _|r6|j� X dS )z(Close the connection to the SMTP server.N)rH r; rX )r rH rX r r r r; � s z SMTP.closec C s. | j d�}d | _| _i | _d| _| j� |S )zTerminate the SMTP session.�quitNF)rB r} ru r7 r~ r; )r �resr r r r� � s z SMTP.quit)rP r N)r )r )r )r )r )N)N)N)NNN)1r r r r rE rH ru r| r} r~ � SMTP_PORTrW r= �_GLOBAL_DEFAULT_TIMEOUTr r@ rD rF rM rO r: ra rc rY rB rt r1 r� r� r� r� r� r� r� r. r� r� r� r� ry r� r� r� r� r� r� r� r; r� r r r r r � s^ - " 1 3 ' B 8 gL c @ s8 e Zd ZdZeZdddddejddfdd�Zdd� Z dS ) �SMTP_SSLa� This is a subclass derived from SMTP that connects over an SSL encrypted socket (to use this class you need a socket module that was compiled with SSL support).

If port is omitted, the standard SMTP-over-SSL port (465) is used. local_hostname and source_address have the same meaning as they do in the SMTP class. keyfile and certfile are also optional - they can contain a PEM formatted private key and certificate chain file for the SSL connection. context also optional, can contain a SSLContext, and is an alternative to keyfile and certfile; If it is specified both keyfile and certfile must be None. r r Nc C s� |d k r|d k rt d��|d k r0|d k r0t d��|d k s@|d k rVdd l} | jdtd� || _|| _|d krxtj||d�}|| _t j | |||||� d S )Nz4context and keyfile arguments are mutually exclusivez5context and certfile arguments are mutually exclusiver zAkeyfile and certfile are deprecated, use a custom context insteadr� )r� r� ) rU r� r� r� r� r� r� r� r� r r ) r r> r? r< r� r� r6 r9 r� r� r r r r � s zSMTP_SSL.__init__c C sD | j dkr| jd||f� tj||f|| j�}| jj|| jd�}|S )Nr zconnect:)r� )rE rM r= rN r9 r� r� r5 )r r> r? r6 Z new_socketr r r rO s zSMTP_SSL._get_socket) r r r r � SMTP_SSL_PORTrW r= r� r rO r r r r r� � s r� i� c @ s0 e Zd ZdZdZdeddfdd�Zd d d �ZdS ) �LMTPa� LMTP - Local Mail Transfer Protocol The LMTP protocol, which is very similar to ESMTP, is heavily based on the standard SMTP client. It's common to use Unix sockets for LMTP, so our connect() method must support that as well as a regular host:port server. local_hostname and source_address have the same meaning as they do in the SMTP class. To specify a Unix socket, you must use an absolute path as the host, starting with a '/'. Authentication is supported, using the regular SMTP mechanism. When using a Unix socket, LMTP generally don't support or require any authentication, but your mileage might vary.Zlhlor Nc C s t j| ||||d� dS )zInitialize a new instance.)r< r9 N)r r )r r> r? r< r9 r r r r ) s z LMTP.__init__rP r c C s� |d dkr t j| |||d�S y(tjtjtj�| _d| _| jj|� W nB tk r� | jdkrl| j d|� | jr|| jj � d| _� Y nX | j � \}}| jdkr�| j d|� ||fS )z=Connect to the LMTP daemon, on either a Unix or a TCP socket.r �/)r9 Nz connect fail:zconnect:) r r: r= ZAF_UNIXZ SOCK_STREAMrX rH rV rE rM r; rY )r r> r? r9 r r r r r r: / s" z LMTP.connect)rP r N)r r r r r| � LMTP_PORTr r: r r r r r� s r� �__main__c C s( t jj| d � t jj� t jj� j� S )Nz: )rK �stdout�write�flush�stdinrk r% )�promptr r r r� I s r� r� r� �,zEnter message, end with ^D:r zMessage length is %drP rG )@r r= r� r+ Z email.utilsr" Z email.messageZemail.generatorr� r� r� rJ rK Zemail.base64mimer r� �__all__r� r� r- r� rl �compile�Ir� rV r r r r r r r r r r r r* r r/ r0 r� � ImportErrorr� r r� rn r� r� r r� Zfromaddrr� ZtoaddrsrI r r� rk rq rm ZserverrF r� r� r r r r �<module>!

On other boxes the dynamic range is limited to that of a 754 double, and "add a half and chop" rounding is used to reduce the precision to 53 bits.

Opcodes that operate on a variable number of objects generally don't embed the count of objects in the opcode, or pull it off the stack. Instead the MARK opcode is used to push a special marker object on the stack, and then some other opcodes grab all the objects from the top of the stack down to (but not including) the topmost marker object. � stackslicea� An object representing a contiguous slice of the stack. This is used in conjunction with markobject, to represent all of the stack following the topmost markobject. For example, the POP_MARK opcode changes the stack from [..., markobject, stackslice] to [...] No matter how many object are on the stack after the topmost markobject, POP_MARK gets rid of all of them (including the topmost markobject too). c @ s e Zd Zd Zdd � Zd S ) � OpcodeInfor �code�arg� stack_before� stack_after�protor c C sJ || _ || _|| _x |D ]}qW || _x |D ]}q,W || _|| _|| _d S )N)r rr rs rt ru rv r ) r r rr rs rt ru rv r �xr r r r T s zOpcodeInfo.__init__N)r rr rs rt ru rv r )r r r r r r r r r rq 5 s rq ZINT�Ia� Push an integer or bool. The argument is a newline-terminated decimal literal string. The intent may have been that this always fit in a short Python int, but INT can be generated in pickles written on a 64-bit box that require a Python long on a 32-bit box. The difference between this and LONG then is that INT skips a trailing 'L', and produces a short int whenever possible. Another difference is due to that, when bool was introduced as a distinct type in 2.3, builtin names True and False were also added to 2.2.2, mapping to ints 1 and 0. For compatibility in both directions, True gets pickled as INT + "I01\n", and False as INT + "I00\n". Leading zeroes are never produced for a genuine integer. The 2.3 (and later) unpicklers special-case these and return bool instead; earlier unpicklers ignore the leading "0" and return the int. )r rr rs rt ru rv r ZBININT�Ja1 Push a four-byte signed integer. This handles the full range of Python (short) integers on a 32-bit box, directly as binary bytes (1 for the opcode and 4 for the integer). If the integer is non-negative and fits in 1 or 2 bytes, pickling via BININT1 or BININT2 saves space. ZBININT1�Kz�Push a one-byte unsigned integer. This is a space optimization for pickling very small non-negative ints, in range(256). ZBININT2�Mz�Push a two-byte unsigned integer. This is a space optimization for pickling small positive ints, in range(256, 2**16). Integers in range(256) can also be pickled via BININT2, but BININT1 instead saves a byte. ZLONG�La� Push a long integer. The same as INT, except that the literal ends with 'L', and always unpickles to a Python long. There doesn't seem a real purpose to the trailing 'L'. Note that LONG takes time quadratic in the number of digits when unpickling (this is simply due to the nature of decimal->binary conversion). Proto 2 added linear-time (in C; still quadratic-time in Python) LONG1 and LONG4 opcodes. ZLONG1� z|Long integer using one-byte length. A more efficient encoding of a Python long; the long1 encoding says it all.ZLONG4� z~Long integer using found-byte length. A more efficient encoding of a Python long; the long4 encoding says it all.�STRING�Sa� Push a Python string object. The argument is a repr-style string, with bracketing quote characters, and perhaps embedded escapes. The argument extends until the next newline character. These are usually decoded into a str instance using the encoding given to the Unpickler constructor. or the default, 'ASCII'. If the encoding given was 'bytes' however, they will be decoded as bytes object instead. Z BINSTRING�Ta� Push a Python string object. There are two arguments: the first is a 4-byte little-endian signed int giving the number of bytes in the string, and the second is that many bytes, which are taken literally as the string content. These are usually decoded into a str instance using the encoding given to the Unpickler constructor. or the default, 'ASCII'. If the encoding given was 'bytes' however, they will be decoded as bytes object instead. ZSHORT_BINSTRING�Ua� Push a Python string object. There are two arguments: the first is a 1-byte unsigned int giving the number of bytes in the string, and the second is that many bytes, which are taken literally as the string content. These are usually decoded into a str instance using the encoding given to the Unpickler constructor. or the default, 'ASCII'. If the encoding given was 'bytes' however, they will be decoded as bytes object instead. ZBINBYTES�Bz�Push a Python bytes object. There are two arguments: the first is a 4-byte little-endian unsigned int giving the number of bytes, and the second is that many bytes, which are taken literally as the bytes content. ZSHORT_BINBYTES�Cz�Push a Python bytes object. There are two arguments: the first is a 1-byte unsigned int giving the number of bytes, and the second is that many bytes, which are taken literally as the string content. Z BINBYTES8� z�Push a Python bytes object. There are two arguments: the first is an 8-byte unsigned int giving the number of bytes in the string, and the second is that many bytes, which are taken literally as the string content. ZNONE�NzPush None on the stack.ZNEWTRUE� zPush True onto the stack.ZNEWFALSE� zPush False onto the stack.�UNICODE�Vz�Push a Python Unicode string object. The argument is a raw-unicode-escape encoding of a Unicode string, and so may contain embedded escape sequences. The argument extends until the next newline character. ZSHORT_BINUNICODE� a Push a Python Unicode string object. There are two arguments: the first is a 1-byte little-endian signed int giving the number of bytes in the string. The second is that many bytes, and is the UTF-8 encoding of the Unicode string. Z BINUNICODE�Xa Push a Python Unicode string object. There are two arguments: the first is a 4-byte little-endian unsigned int giving the number of bytes in the string. The second is that many bytes, and is the UTF-8 encoding of the Unicode string. Z BINUNICODE8� a Push a Python Unicode string object. There are two arguments: the first is an 8-byte little-endian signed int giving the number of bytes in the string. The second is that many bytes, and is the UTF-8 encoding of the Unicode string. ZFLOAT�Fa� Newline-terminated decimal float literal. The argument is repr(a_float), and in general requires 17 significant digits for roundtrip conversion to be an identity (this is so for IEEE-754 double precision values, which is what Python float maps to on most boxes). In general, FLOAT cannot be used to transport infinities, NaNs, or minus zero across boxes (or even on a single box, if the platform C library can't read the strings it produces for such things -- Windows is like that), but may do less damage than BINFLOAT on boxes with greater precision or dynamic range than IEEE-754 double. ZBINFLOAT�Ga� Float stored in binary form, with 8 bytes of data. This generally requires less than half the space of FLOAT encoding. In general, BINFLOAT cannot be used to transport infinities, NaNs, or minus zero, raises an exception if the exponent exceeds the range of an IEEE-754 double, and retains no more than 53 bits of precision (if there are more than that, "add a half and chop" rounding is used to cut it back to 53 significant bits). Z EMPTY_LIST�]zPush an empty list.ZAPPEND�az�Append an object to a list. Stack before: ... pylist anyobject Stack after: ... pylist+[anyobject] although pylist is really extended in-place. ZAPPENDS�ez�Extend a list by a slice of stack objects. Stack before: ... pylist markobject stackslice Stack after: ... pylist+stackslice although pylist is really extended in-place. ZLIST�las Build a list out of the topmost stack slice, after markobject. All the stack entries following the topmost markobject are placed into a single Python list, which single list object replaces all of the stack from the topmost markobject onward. For example, Stack before: ... markobject 1 2 3 'abc' Stack after: ... [1, 2, 3, 'abc'] Z EMPTY_TUPLE�)zPush an empty tuple.ZTUPLE�tav Build a tuple out of the topmost stack slice, after markobject. All the stack entries following the topmost markobject are placed into a single Python tuple, which single tuple object replaces all of the stack from the topmost markobject onward. For example, Stack before: ... markobject 1 2 3 'abc' Stack after: ... (1, 2, 3, 'abc') ZTUPLE1� z�Build a one-tuple out of the topmost item on the stack. This code pops one value off the stack and pushes a tuple of length 1 whose one item is that value back onto it. In other words: stack[-1] = tuple(stack[-1:]) ZTUPLE2� a Build a two-tuple out of the top two items on the stack. This code pops two values off the stack and pushes a tuple of length 2 whose items are those values back onto it. In other words: stack[-2:] = [tuple(stack[-2:])] ZTUPLE3� a Build a three-tuple out of the top three items on the stack. This code pops three values off the stack and pushes a tuple of length 3 whose items are those values back onto it. In other words: stack[-3:] = [tuple(stack[-3:])] Z EMPTY_DICT�}zPush an empty dict.ZDICT�da� Build a dict out of the topmost stack slice, after markobject. All the stack entries following the topmost markobject are placed into a single Python dict, which single dict object replaces all of the stack from the topmost markobject onward. The stack slice alternates key, value, key, value, .... For example, Stack before: ... markobject 1 2 3 'abc' Stack after: ... {1: 2, 3: 'abc'} ZSETITEMrS z�Add a key+value pair to an existing dict. Stack before: ... pydict key value Stack after: ... pydict where pydict has been modified via pydict[key] = value. ZSETITEMS�ua\ Add an arbitrary number of key+value pairs to an existing dict. The slice of the stack following the topmost markobject is taken as an alternating sequence of keys and values, added to the dict immediately under the topmost markobject. Everything at and after the topmost markobject is popped, leaving the mutated dict at the top of the stack. Stack before: ... pydict markobject key_1 value_1 ... key_n value_n Stack after: ... pydict where pydict has been modified via pydict[key_i] = value_i for i in 1, 2, ..., n, and in that order. Z EMPTY_SET� zPush an empty set.ZADDITEMS� a$ Add an arbitrary number of items to an existing set. The slice of the stack following the topmost markobject is taken as a sequence of items, added to the set immediately under the topmost markobject. Everything at and after the topmost markobject is popped, leaving the mutated set at the top of the stack. Stack before: ... pyset markobject item_1 ... item_n Stack after: ... pyset where pyset has been modified via pyset.add(item_i) = item_i for i in 1, 2, ..., n, and in that order. Z FROZENSET� az Build a frozenset out of the topmost slice, after markobject. All the stack entries following the topmost markobject are placed into a single Python frozenset, which single frozenset object replaces all of the stack from the topmost markobject onward. For example, Stack before: ... markobject 1 2 3 Stack after: ... frozenset({1, 2, 3}) �POP�0z<Discard the top stack item, shrinking the stack by one item.ZDUP�2z=Push the top stack item onto the stack again, duplicating it.�MARK�(z�Push markobject onto the stack. markobject is a unique object, used by other opcodes to identify a region of the stack containing a variable number of objects for them to work on. See markobject.doc for more detail. ZPOP_MARK�1a Pop all the stack objects at and above the topmost markobject. When an opcode using a variable number of stack objects is done, POP_MARK is used to remove those objects, and to remove the markobject that delimited their starting position on the stack. �GET�gz�Read an object from the memo and push it on the stack. The index of the memo object to push is given by the newline-terminated decimal string following. BINGET and LONG_BINGET are space-optimized versions. �BINGET�hz�Read an object from the memo and push it on the stack. The index of the memo object to push is given by the 1-byte unsigned integer following. � LONG_BINGET�jz�Read an object from the memo and push it on the stack. The index of the memo object to push is given by the 4-byte unsigned little-endian integer following. �PUT�pz�Store the stack top into the memo. The stack is not popped. The index of the memo location to write into is given by the newline- terminated decimal string following. BINPUT and LONG_BINPUT are space-optimized versions. �BINPUTr5 z�Store the stack top into the memo. The stack is not popped. The index of the memo location to write into is given by the 1-byte unsigned integer following. � LONG_BINPUT�rz�Store the stack top into the memo. The stack is not popped. The index of the memo location to write into is given by the 4-byte unsigned little-endian integer following. �MEMOIZE� z�Store the stack top into the memo. The stack is not popped. The index of the memo location to write is the number of elements currently present in the memo. ZEXT1� a� Extension code. This code and the similar EXT2 and EXT4 allow using a registry of popular objects that are pickled by name, typically classes. It is envisioned that through a global negotiation and registration process, third parties can set up a mapping between ints and object names. In order to guarantee pickle interchangeability, the extension code registry ought to be global, although a range of codes may be reserved for private use. EXT1 has a 1-byte integer argument. This is used to index into the extension registry, and the object at that index is pushed on the stack. ZEXT2� zNExtension code. See EXT1. EXT2 has a two-byte integer argument. ZEXT4� zOExtension code. See EXT1. EXT4 has a four-byte integer argument. ZGLOBAL�ca� Push a global object (module.attr) on the stack. Two newline-terminated strings follow the GLOBAL opcode. The first is taken as a module name, and the second as a class name. The class object module.class is pushed on the stack. More accurately, the object returned by self.find_class(module, class) is pushed on the stack, so unpickling subclasses can override this form of lookup. Z STACK_GLOBAL� z7Push a global object (module.attr) on the stack. ZREDUCE�RaL Push an object built from a callable and an argument tuple. The opcode is named to remind of the __reduce__() method. Stack before: ... callable pytuple Stack after: ... callable(*pytuple) The callable and the argument tuple are the first two items returned by a __reduce__ method. Applying the callable to the argtuple is supposed to reproduce the original object, or at least get it started. If the __reduce__ method returns a 3-tuple, the last component is an argument to be passed to the object's __setstate__, and then the REDUCE opcode is followed by code to create setstate's argument, and then a BUILD opcode to apply __setstate__ to that argument. If not isinstance(callable, type), REDUCE complains unless the callable has been registered with the copyreg module's safe_constructors dict, or the callable has a magic '__safe_for_unpickling__' attribute with a true value. I'm not sure why it does this, but I've sure seen this complaint often enough when I didn't want to <wink>. ZBUILD�ba� Finish building an object, via __setstate__ or dict update. Stack before: ... anyobject argument Stack after: ... anyobject where anyobject may have been mutated, as follows: If the object has a __setstate__ method, anyobject.__setstate__(argument) is called. Else the argument must be a dict, the object must have a __dict__, and the object is updated via anyobject.__dict__.update(argument) ZINST�iaq Build a class instance. This is the protocol 0 version of protocol 1's OBJ opcode. INST is followed by two newline-terminated strings, giving a module and class name, just as for the GLOBAL opcode (and see GLOBAL for more details about that). self.find_class(module, name) is used to get a class object. In addition, all the objects on the stack following the topmost markobject are gathered into a tuple and popped (along with the topmost markobject), just as for the TUPLE opcode. Now it gets complicated. If all of these are true: + The argtuple is empty (markobject was at the top of the stack at the start). + The class object does not have a __getinitargs__ attribute. then we want to create an old-style class instance without invoking its __init__() method (pickle has waffled on this over the years; not calling __init__() is current wisdom). In this case, an instance of an old-style dummy class is created, and then we try to rebind its __class__ attribute to the desired class object. If this succeeds, the new instance object is pushed on the stack, and we're done. Else (the argtuple is not empty, it's not an old-style class object, or the class object does have a __getinitargs__ attribute), the code first insists that the class object have a __safe_for_unpickling__ attribute. Unlike as for the __safe_for_unpickling__ check in REDUCE, it doesn't matter whether this attribute has a true or false value, it only matters whether it exists (XXX this is a bug). If __safe_for_unpickling__ doesn't exist, UnpicklingError is raised. Else (the class object does have a __safe_for_unpickling__ attr), the class object obtained from INST's arguments is applied to the argtuple obtained from the stack, and the resulting instance object is pushed on the stack. NOTE: checks for __safe_for_unpickling__ went away in Python 2.3. NOTE: the distinction between old-style and new-style classes does not make sense in Python 3. ZOBJ�oa� Build a class instance. This is the protocol 1 version of protocol 0's INST opcode, and is very much like it. The major difference is that the class object is taken off the stack, allowing it to be retrieved from the memo repeatedly if several instances of the same class are created. This can be much more efficient (in both time and space) than repeatedly embedding the module and class names in INST opcodes. Unlike INST, OBJ takes no arguments from the opcode stream. Instead the class object is taken off the stack, immediately above the topmost markobject: Stack before: ... markobject classobject stackslice Stack after: ... new_instance_object As for INST, the remainder of the stack above the markobject is gathered into an argument tuple, and then the logic seems identical, except that no __safe_for_unpickling__ check is done (XXX this is a bug). See INST for the gory details. NOTE: In Python 2.3, INST and OBJ are identical except for how they get the class object. That was always the intent; the implementations had diverged for accidental reasons. ZNEWOBJ� aL Build an object instance. The stack before should be thought of as containing a class object followed by an argument tuple (the tuple being the stack top). Call these cls and args. They are popped off the stack, and the value returned by cls.__new__(cls, *args) is pushed back onto the stack. Z NEWOBJ_EX� au Build an object instance. The stack before should be thought of as containing a class object followed by an argument tuple and by a keyword argument dict (the dict being the stack top). Call these cls and args. They are popped off the stack, and the value returned by cls.__new__(cls, *args, *kwargs) is pushed back onto the stack. �PROTO� z�Protocol version indicator. For protocol 2 and above, a pickle must start with this opcode. The argument is the protocol version, an int in range(2, 256). ZSTOP�.z�Stop the unpickling machine. Every pickle ends with this opcode. The object at the top of the stack is popped, and that's the result of unpickling. The stack should be empty then. �FRAME� z�Indicate the beginning of a new frame. The unpickler may use this opcode to safely prefetch data from its underlying stream. ZPERSID�Pa Push an object identified by a persistent ID. The pickle module doesn't define what a persistent ID means. PERSID's argument is a newline-terminated str-style (no embedded escapes, no bracketing quote characters) string, which *is* "the persistent ID". The unpickler passes this string to self.persistent_load(). Whatever object that returns is pushed on the stack. There is no implementation of persistent_load() in Python's unpickler: it must be supplied by an unpickler subclass. Z BINPERSID�QaX Push an object identified by a persistent ID. Like PERSID, except the persistent ID is popped off the stack (instead of being a string embedded in the opcode bytestream). The persistent ID is passed to self.persistent_load(), and whatever object that returns is pushed on the stack. See PERSID for more detail. z%repeated name %r at indices %d and %dz%repeated code %r at indices %d and %dFc C s t j� }x�tjD ]�}tjd|�s2| rtd| � qtt|�}t|t � sTt |�dkrj| rtd||f � q|j d�}||kr�| r�td||f � || }|j |kr�t d|||j f ��||= qt d||f ��qW |�rd g}x(|j� D ] \}}|jd |j |f � q�W t d j|���d S ) Nz[A-Z][A-Z0-9_]+$z0skipping %r: it doesn't look like an opcode namer z5skipping %r: value %r doesn't look like a pickle codezlatin-1z+checking name %r w/ code %r for consistencyzBfor pickle code %r, pickle.py uses name %r but we're using name %rzPpickle.py appears to have a pickle opcode with name %r and code %r, but we don'tz=we appear to have pickle opcodes that pickle.py doesn't have:z name %r with code %r� )�code2op�copy�pickle�__all__�re�match�print�getattrre ri r r3 r r �items�append�join)�verboser� r Z picklecoder� �msgrr r r r �assure_pickle_consistency s> r� c c s� t | t�rtj| �} t| d�r&| j}ndd� }x�|� }| jd�}tj|j d��}|d kr�|dkrjt d��n t d|d krzd n||f ��|j d kr�d }n |j j | �}|r�||||� fV n |||fV |d kr0P q0W d S ) N�tellc S s d S )Nr r r r r �<lambda>� s z_genops.<locals>.<lambda>r zlatin-1� z#pickle exhausted before seeing STOPz!at position %s, opcode %r unknownz <unknown>� .) re � bytes_types�io�BytesIO�hasattrr� r r� �getr3 r rs r )r � yield_end_posZgetpos�posrr �opcoders r r r �_genops� s. r� c C s t | �S )N)r� )r� r r r r � s c C s� d}d}t � }i }g }d}d}x�t| dd�D ]�\}} } } d|jkr\|j| � |j|| f� q,|jdkr�t|�} |j| � |j|| f� q,d|jkr�q,d|jkr�|j|kr�|j}d || < |j|| f� q,|jd k�r| |kr�| }| dkr�| | | � }n|j| | f� q,|j| | f� q,W ~tj� } | j |� t j | |�}|d k�rJ|j j � d} x�|D ]x\}} ||k�r�| |k�rt�qT|j| �}| || < | d 7 } n&||k�r�|j|| �}n | || � }|j j� |j |� �qTW |j j� | j� S ) Nr� r� r r� T)r� r� r� r� r r )rm r� r �addr� r rv r� r� �writer� Z_PicklerZframerZ start_framing�putr� Z commit_frameZ end_framing�getvalue)r� r� r� ZoldidsZnewids�opcodesrv Z protoheaderr� rs r� Zend_pos�idx�outZpickler�opr r r r r � sd c C s g }|d kri }d }g }d| }d } |} �x�t | �D �]�\} } } | d k rZtd| d|d� dt| j�dd � |t|� | jf }t|| j�}| j}| j }t|�}d }t |ks�| jdko�|o�|d t k�rD|�r<|j � }|d kr�d}nd| }x|d! t k �r|j � q�W |j � y|j t �}W n t k �r8 d }Y nX nd } }| jd"k�r�| jdk�rnt|�}d| }n| }||k�r�d| } n,|�s�d} n |d# t k�r�d} n |d$ ||< n*| jd%k�r�| |k�r�|| g}nd| } | d k �s�|�r0|ddt| j� 7 }| d k �r |dt| � 7 }|�r0|d| 7 }|�rz|d| t|� 7 }t|�} | dk�r`|} |d| jjdd�d 7 }t||d� | �r�t | ��t|�|k �r�t d|t|�f ��|�r�|| d �= t |k�r�|j| � |j|� q4W td ||d� |�r t d | ��d S )&Nr � z%5d:)�end�filez %-4s %s%sr� z (MARK at unknown opcode offset)z (MARK at %d)r zno MARK exists on stackr� r� r� r� z(as %d)zmemo key %r already definedz'stack is empty -- can't store into memoz"can't store markobject in the memor� r� r� z&memo key %r has never been stored into� �2 r� )r� z3tries to pop %d items from stack with only %d itemsz highest protocol among opcodes =z stack not empty after STOP: %rr- r- r- r- )r� r� r� r� r- r- )r� r� r� )r r� �reprrr r r �maxrv rt ru � markobject�pop�indexr r �splitr� �extend)r� r� �memo� indentlevel�annotate�stackZmaxprotoZ markstackZ indentchunkZerrormsgZannocolr� rs r� �lineZbefore�afterZnumtopopZmarkmsgZmarkposZmemo_idxr r r r % s� - c @ s e Zd Zdd� ZdS )�_Examplec C s || _ d S )N)�value)r r� r r r r � s z_Example.__init__N)r r r r r r r r r� � s r� a� >>> import pickle >>> x = [1, 2, (3, 4), {b'abc': "def"}] >>> pkl0 = pickle.dumps(x, 0) >>> dis(pkl0) 0: ( MARK 1: l LIST (MARK at 0) 2: p PUT 0 5: L LONG 1 9: a APPEND 10: L LONG 2 14: a APPEND 15: ( MARK 16: L LONG 3 20: L LONG 4 24: t TUPLE (MARK at 15) 25: p PUT 1 28: a APPEND 29: ( MARK 30: d DICT (MARK at 29) 31: p PUT 2 34: c GLOBAL '_codecs encode' 50: p PUT 3 53: ( MARK 54: V UNICODE 'abc' 59: p PUT 4 62: V UNICODE 'latin1' 70: p PUT 5 73: t TUPLE (MARK at 53) 74: p PUT 6 77: R REDUCE 78: p PUT 7 81: V UNICODE 'def' 86: p PUT 8 89: s SETITEM 90: a APPEND 91: .

Usage: %(program)s [options] [localhost:localport [remotehost:remoteport]] Options: --nosetuid -n This program generally tries to setuid `nobody', unless this flag is set. The setuid call will fail if this program is not run as root (in which case, use this flag). --version -V Print the version number and exit. --class classname -c classname Use `classname' as the concrete SMTP proxy class. Uses `PureProxy' by default. --size limit -s limit Restrict the total size of the incoming message to "limit" number of bytes via the RFC 1870 SIZE extension. Defaults to 33554432 bytes. --smtputf8 -u Enable the SMTPUTF8 extension and behave as an RFC 6531 smtp proxy. --debug -d Turn on debugging prints. --help -h Print this message and exit. Version: %(__version__)s If localhost is not given then `localhost' is used, and if localport is not given then 8025 is used. If remotehost is not given then `localhost' is used, and if remoteport is not given, then 25 is used. � N)�warn)� get_addr_spec�get_angle_addr� SMTPChannel� SMTPServer�DebuggingServer� PureProxy�

socket connection to our smtp port. mailfrom is the raw address the client claims the message is coming from. rcpttos is a list of raw addresses the client wishes to deliver the message to. data is a string containing the entire full text of the message, headers (if supplied) and all. It has been `de-transparencied' according to RFC 821, Section 4.5.2. In other words, a line containing a `.' followed by other text has had the leading dot removed. kwargs is a dictionary containing additional information. It is empty if decode_data=True was given as init parameter, otherwise it will contain the following keys: 'mail_options': list of parameters to the mail command. All elements are uppercase strings. Example: ['BODY=8BITMIME', 'SMTPUTF8']. 'rcpt_options': same, for the rcpt command. This function should return None for a normal `250 Ok' response; otherwise, it should return the desired response string in RFC 821 format.

Returns a new list containing elements from the population while leaving the original population unchanged. The resulting list is in selection order so that all sub-slices will also be valid random samples. This allows raffle winners (the sample) to be partitioned into grand prize and second place winners (the subslices). Members of the population need not be hashable or unique. If the population contains repeats, then each occurrence is a possible selection in the sample. To choose a sample in a range of integers, use range as an argument.

This module avoids a number of common traps for measuring execution times. See also Tim Peters' introduction to the Algorithms chapter in the Python Cookbook, published by O'Reilly. Library usage: see the Timer class. Command line usage: python timeit.py [-n N] [-r N] [-s S] [-t] [-c] [-p] [-h] [--] [statement] Options: -n/--number N: how many times to execute 'statement' (default: see below) -r/--repeat N: how many times to repeat the timer (default 3) -s/--setup S: statement to be executed once initially (default 'pass'). Execution time of this setup statement is NOT timed. -p/--process: use time.process_time() (default is time.perf_counter()) -t/--time: use time.time() (deprecated) -c/--clock: use time.clock() (deprecated) -v/--verbose: print raw timing results; repeat for more digits precision -u/--unit: set the output time unit (usec, msec, or sec) -h/--help: print this usage message and exit --: separate options from statement, use when statement starts with - statement: statement to be timed (default 'pass') A multi-line statement may be given by specifying each line as a separate argument; indented lines are possible by enclosing an argument in quotes and using leading spaces. Multiple -s options are treated similarly. If -n is not given, a suitable number of loops is calculated by trying successive powers of 10 until the total time is at least 0.2 seconds. Note: there is a certain baseline overhead associated with executing a pass statement. It differs between versions. The code here doesn't try to hide it, but you should be aware of it. The baseline overhead can be measured by invoking the program without arguments.

The constructor takes a statement to be timed, an additional statement used for setup, and a timer function. Both statements default to 'pass'; the timer function is platform-dependent (see module doc string). If 'globals' is specified, the code will be executed within that namespace (as opposed to inside timeit's namespace). To measure the execution time of the first statement, use the timeit() method. The repeat() method is a convenience to call timeit() multiple times and return a list of results. The statements may contain newlines, as long as they don't contain multi-line string literals. �passNc C s� || _ i }|dkrt� n|}d}t|t�rJt|td� |d }t|d�}n*t|�rl||d< |d7 }d}d}ntd ��t|t�r�t|| td� t|d �}n&t|�r�||d < |d 7 }d }ntd��t j |||d�} | | _ t| td�} t | ||� |d | _ dS )z#Constructor.

Typical use: t = Timer(...) # outside the try/except try: t.timeit(...) # or t.repeat(...) except: t.print_exc() The advantage over the standard traceback is that source lines in the compiled template will be displayed.

To be precise, this executes the setup statement once, and then returns the time it takes to execute the main statement a number of times, as a float measured in seconds. The argument is the number of times through the loop, defaulting to one million. The main statement, the setup statement and the timer function to be used are passed to the constructor.

This is a convenience function that calls the timeit() repeatedly, returning a list of results. The first argument specifies how many times to call timeit(), defaulting to 3; the second argument specifies the timer argument, defaulting to one million. Note: it's tempting to calculate mean and standard deviation from the result vector and report these. However, this is not very useful. In a typical case, the lowest value gives a lower bound for how fast your machine can run the given code snippet; higher values in the result vector are typically not caused by variability in Python's speed, but by other processes interfering with your timing accuracy. So the min() of the result is probably the only number you should be interested in. After that, you should look at the entire vector and apply common sense rather than statistics. )�ranger �append)r# r r3 �r�i�tr r r r � s z Timer.repeatc C sF x<t dd�D ].}d| }| j|�}|r0|||� |dkr P q W ||fS )a� Return the number of loops and time taken so that total time >= 0.2.

Returns ``(number, time_taken)``.

The optional 'args' argument specifies the command line to be parsed, defaulting to sys.argv[1:]. The return value is an exit code to be passed to sys.exit(); it may be None to indicate success.

This method is used both when an enum class is given a value to match to an enumeration member (i.e. Color(3)) and for the functional API (i.e. Color = Enum('Color', names='RED GREEN BLUE')). When used for the functional API: `value` will be the name of the new class. `names` should be either a string of white-space/comma delimited names (values will start at `start`), or an iterator/mapping of name, value pairs. `module` should be set to the module this class is being created in; if it is not set, an attempt to find that module will be made, but if it fails the class will not be picklable. `qualname` should be set to the actual location this class can be found at in its module; by default it is set to the global scope. If this is not correct, unpickling will fail in some circumstances. `type`, if set, will be mixed in as the first base class.

Interpreters constructed with this class obey the following conventions: 1. End of file on input is processed as the command 'EOF'. 2. A command is parsed out of each line by collecting the prefix composed of characters in the identchars member. 3. A command `foo' is dispatched to a method 'do_foo()'; the do_ method is passed a single argument consisting of the remainder of the line. 4. Typing an empty line repeats the last command. (Actually, it calls the method `emptyline', which may be overridden in a subclass.) 5. There is a predefined `help' method. Given an argument `topic', it calls the command `help_topic'. With no arguments, it lists all topics with defined help_ functions, broken into up to three topics; documented commands, miscellaneous help topics, and undocumented commands. 6. The command '?' is a synonym for `help'. The command '!' is a synonym for `shell', if a do_shell method exists. 7. If completion is enabled, completing commands will be done automatically, and completing of commands args is done by calling complete_foo() with arguments text, line, begidx, endidx. text is string we are matching against, all returned matches must begin with it. line is the current input line (lstripped), begidx and endidx are the beginning and end indexes of the text being matched, which could be used to provide different completion depending upon which position the argument is in. The `default' method may be overridden to intercept commands for which there is no do_ method. The `completedefault' method may be overridden to intercept completions for commands that have no complete_ method. The data member `self.ruler' sets the character used to draw separator lines in the help messages. If empty, no ruler line is drawn. It defaults to "=". If the value of `self.intro' is nonempty when the cmdloop method is called, it is printed out on interpreter startup. This value may be overridden via an optional argument to the cmdloop() method. The data members `self.doc_header', `self.misc_header', and `self.undoc_header' set the headers used for the help function's listings of documented functions, miscellaneous topics, and undocumented functions respectively. � N�Cmdz(Cmd) �_c @ s� e Zd ZdZeZeZdZdZ dZ dZ dZ dZ dZdZd Zd0d d �Zd1d d�Zdd� Zdd� Zdd� Zdd� Zdd� Zdd� Zdd � Zd d � Zd d � Zd!d"� Z d#d$� Z d%d&� Z d'd(� Z d)d*� Z d+d,� Z!d2d.d/�Z"dS )3r a A simple framework for writing line-oriented command interpreters. These are often useful for test harnesses, administrative tools, and prototypes that will later be wrapped in a more sophisticated interface. A Cmd instance or subclass instance is a line-oriented interpreter framework. There is no good reason to instantiate Cmd itself; rather, it's useful as a superclass of an interpreter class you define yourself in order to inherit Cmd's methods and encapsulate action methods. �=� Nz(Documented commands (type help <topic>):zMiscellaneous help topics:zUndocumented commands:z*** No help on %s� �tabc C s@ |dk r|| _ ntj | _ |dk r(|| _ntj| _g | _|| _dS )a� Instantiate a line-oriented interpreter framework.

If pathname is a package directory, search the directory and all package subdirectories recursively for all *.py and enter the modules into the archive. If pathname is a plain directory, listdir *.py and enter all modules. Else, pathname must be a Python *.py file and the module will be put into the archive. Added modules are always module.pyc. This method will compile the module.py into module.pyc if necessary. If filterfunc(pathname) is given, it is called with every argument.

Example: >>> check_output(["ls", "-l", "/dev/null"]) b'crw-rw-rw- 1 root root 1, 3 Oct 18 2007 /dev/null\n' The stdout argument is not allowed as it is used internally.

The returned instance will have attributes args, returncode, stdout and stderr. By default, stdout and stderr are not captured, and those attributes will be None.

The CalledProcessError object will have the return code in the returncode attribute, and output & stderr attributes if those streams were captured. If timeout is given, and the process takes too long, a TimeoutExpired exception will be raised. There is an optional argument "input", allowing you to pass a string to the subprocess's stdin. If you use this argument you may not also use the Popen constructor's "stdin" argument, as it will be used internally. The other arguments are the same as for the Popen constructor.

A quoted string can be embedded in an argument. 3) A double quotation mark preceded by a backslash is interpreted as a literal double quotation mark. 4) Backslashes are interpreted literally, unless they immediately precede a double quotation mark. 5) If backslashes immediately precede a double quotation mark, every pair of backslashes is interpreted as a literal backslash. If the number of backslashes is odd, the last backslash escapes the next double quotation mark as described in rule 3.

Execute the string 'cmd' in a shell with 'check_output' and return a 2-tuple (status, output). The locale encoding is used to decode the output and process newlines. A trailing newline is stripped from the output. The exit status for the command can be interpreted according to the rules for the function 'wait'. Example: >>> import subprocess >>> subprocess.getstatusoutput('ls /bin/ls') (0, '/bin/ls') >>> subprocess.getstatusoutput('cat /bin/junk') (1, 'cat: /bin/junk: No such file or directory') >>> subprocess.getstatusoutput('/bin/junk') (127, 'sh: /bin/junk: not found') >>> subprocess.getstatusoutput('/bin/kill $$') (-15, '') T)�shellru r r NrF � ���r� )r( r# r r r )r �dataZexitcodeZexr r r r& s c C s t | �d S )a% Return output (stdout or stderr) of executing cmd in a shell.

The SOURCE can be the name of a directory, or a filename or a file-like object referring to an existing archive. The content of SOURCE is packed into an application archive in TARGET, which can be a filename or a file-like object. If SOURCE is a directory, TARGET can be omitted and will default to the name of SOURCE with .pyz appended. The created application archive will have a shebang line specifying that it should run with INTERPRETER (there will be no shebang line if INTERPRETER is None), and a __main__.py which runs MAIN (if MAIN is not specified, an existing __main__.py will be used). It is an error to specify MAIN for anything other than a directory source with no __main__.py, and it is an error to omit MAIN if the directory has no __main__.py.

IGNORE is a list of names to ignore, defaults to DEFAULT_IGNORES. HIDE is a list of names to hide, defaults to [os.curdir, os.pardir]. High level usage: x = dircmp(dir1, dir2) x.report() -> prints a report on the differences between dir1 and dir2 or x.report_partial_closure() -> prints report on differences between dir1 and dir2, and reports on common immediate subdirectories. x.report_full_closure() -> like report_partial_closure, but fully recursive. Attributes: left_list, right_list: The files in dir1 and dir2, filtered by hide and ignore. common: a list of names in both dir1 and dir2. left_only, right_only: names only in dir1, dir2. common_dirs: subdirectories in both dir1 and dir2. common_files: files in both dir1 and dir2. common_funny: names in both dir1 and dir2 where the type differs between dir1 and dir2, or the name is not stat-able. same_files: list of identical files. diff_files: list of filenames which differ. funny_files: list of files which could not be compared. subdirs: a dictionary of dircmp objects, keyed by names in common_dirs.

When invoked without arguments: if this thread already owns the lock, increment the recursion level by one, and return immediately. Otherwise, if another thread owns the lock, block until the lock is unlocked. Once the lock is unlocked (not owned by any thread), then grab ownership, set the recursion level to one, and return. If more than one thread is blocked waiting until the lock is unlocked, only one at a time will be able to grab ownership of the lock. There is no return value in this case. When invoked with the blocking argument set to true, do the same thing as when called without arguments, and return true. When invoked with the blocking argument set to false, do not block. If a call without an argument would block, return false immediately; otherwise, do the same thing as when called without arguments, and return true. When invoked with the floating-point timeout argument set to a positive value, block for at most the number of seconds specified by timeout and as long as the lock cannot be acquired.

A condition variable allows one or more threads to wait until they are notified by another thread.

If the calling thread has not acquired the lock when this method is called, a RuntimeError is raised. This method releases the underlying lock, and then blocks until it is awakened by a notify() or notify_all() call for the same condition variable in another thread, or until the optional timeout occurs. Once awakened or timed out, it re-acquires the lock and returns. When the timeout argument is present and not None, it should be a floating point number specifying a timeout for the operation in seconds (or fractions thereof). When the underlying lock is an RLock, it is not released using its release() method, since this may not actually unlock the lock when it was acquired multiple times recursively. Instead, an internal interface of the RLock class is used, which really unlocks it even when it has been recursively acquired several times. Another internal interface is then used to restore the recursion level when the lock is reacquired. z cannot wait on un-acquired lockFNTr g����Mb@?� g�������?) rH r? r( r: rP �appendrG �_time�min�_sleeprF �remove� ValueError)r, r< �waiterZ saved_stateZgotit�endtimeZdelayZ remainingr r r! �wait s> zCondition.waitc C s\ d}|}|� }xH|sV|dk rD|dkr0t � | }n|t � }|dkrDP | j|� |� }qW |S )z�Wait until a condition evaluates to True. predicate should be a callable which result will be interpreted as a boolean value.

When invoked without arguments: if the internal counter is larger than zero on entry, decrement it by one and return immediately. If it is zero on entry, block, waiting until some other thread has called release() to make it larger than zero. This is done with proper interlocking so that if multiple acquire() calls are blocked, release() will wake exactly one of them up. The implementation may pick one at random, so the order in which blocked threads are awakened should not be relied on. There is no return value in this case. When invoked with blocking set to true, do the same thing as when called without arguments, and return true. When invoked with blocking set to false, do not block. If a call without an argument would block, return false immediately; otherwise, do the same thing as when called without arguments, and return true. When invoked with a timeout other than None, it will block for at most timeout seconds. If acquire does not complete successfully in that interval, return false. Return true otherwise.

This blocks the calling thread until the thread whose join() method is called terminates -- either normally or through an unhandled exception or until the optional timeout occurs. When the timeout argument is present and not None, it should be a floating point number specifying a timeout for the operation in seconds (or fractions thereof). As join() always returns None, you must call isAlive() after join() to decide whether a timeout happened -- if the thread is still alive, the join() call timed out. When the timeout argument is not present or None, the operation will block until the thread terminates. A thread can be join()ed many times. join() raises a RuntimeError if an attempt is made to join the current thread as that would cause a deadlock.

When invoked without arguments: if this thread already owns the lock, increment the recursion level by one, and return immediately. Otherwise, if another thread owns the lock, block until the lock is unlocked. Once the lock is unlocked (not owned by any thread), then grab ownership, set the recursion level to one, and return. If more than one thread is blocked waiting until the lock is unlocked, only one at a time will be able to grab ownership of the lock. There is no return value in this case. When invoked with the blocking argument set to true, do the same thing as when called without arguments, and return true. When invoked with the blocking argument set to false, do not block.

If the calling thread has not acquired the lock when this method is called, a RuntimeError is raised. This method releases the underlying lock, and then blocks until it is awakened by a notify() or notify_all() call for the same condition variable in another thread, or until the optional timeout occurs. Once awakened or timed out, it re-acquires the lock and returns. When the timeout argument is present and not None, it should be a floating point number specifying a timeout for the operation in seconds (or fractions thereof). When the underlying lock is an RLock, it is not released using its release() method, since this may not actually unlock the lock when it was acquired multiple times recursively. Instead, an internal interface of the RLock class is used, which really unlocks it even when it has been recursively acquired several times. Another internal interface is then used to restore the recursion level when the lock is reacquired. z cannot wait on un-acquired lockFNTr g����Mb@?� g�������?) rH r? r( r: rP �appendrG �_time�min�_sleeprF �remove� ValueError)r, r< �waiterZ saved_stateZgotit�endtimeZdelayZ remainingr r r! �wait s> zCondition.waitc C s\ d}|}|� }xH|sV|dk rD|dkr0t � | }n|t � }|dkrDP | j|� |� }qW |S )z�Wait until a condition evaluates to True. predicate should be a callable which result will be interpreted as a boolean value.

When invoked without arguments: if the internal counter is larger than zero on entry, decrement it by one and return immediately. If it is zero on entry, block, waiting until some other thread has called release() to make it larger than zero. This is done with proper interlocking so that if multiple acquire() calls are blocked, release() will wake exactly one of them up. The implementation may pick one at random, so the order in which blocked threads are awakened should not be relied on. There is no return value in this case. When invoked with blocking set to true, do the same thing as when called without arguments, and return true. When invoked with blocking set to false, do not block. If a call without an argument would block, return false immediately; otherwise, do the same thing as when called without arguments, and return true. When invoked with a timeout other than None, it will block for at most timeout seconds. If acquire does not complete successfully in that interval, return false. Return true otherwise.

The purpose of this module is to support arithmetic using familiar "schoolhouse" rules and to avoid some of the tricky representation issues associated with binary floating point. The package is especially useful for financial applications or for contexts where users have expectations that are at odds with binary floating point (for instance, in binary floating point, 1.00 % 0.1 gives 0.09999999999999995 instead of 0.0; Decimal('1.00') % Decimal('0.1') returns the expected Decimal('0.00')). Here are some examples of using the decimal module: >>> from decimal import * >>> setcontext(ExtendedContext) >>> Decimal(0) Decimal('0') >>> Decimal('1') Decimal('1') >>> Decimal('-.0123') Decimal('-0.0123') >>> Decimal(123456) Decimal('123456') >>> Decimal('123.45e12345678') Decimal('1.2345E+12345680') >>> Decimal('1.33') + Decimal('1.27') Decimal('2.60') >>> Decimal('12.34') + Decimal('3.87') - Decimal('18.41') Decimal('-2.20') >>> dig = Decimal(1) >>> print(dig / Decimal(3)) 0.333333333 >>> getcontext().prec = 18 >>> print(dig / Decimal(3)) 0.333333333333333333 >>> print(dig.sqrt()) 1 >>> print(Decimal(3).sqrt()) 1.73205080756887729 >>> print(Decimal(3) ** 123) 4.85192780976896427E+58 >>> inf = Decimal(1) / Decimal(0) >>> print(inf) Infinity >>> neginf = Decimal(-1) / Decimal(0) >>> print(neginf) -Infinity >>> print(neginf + inf) NaN >>> print(neginf * inf) -Infinity >>> print(dig / 0) Infinity >>> getcontext().traps[DivisionByZero] = 1 >>> print(dig / 0) Traceback (most recent call last): ... ... ... decimal.DivisionByZero: x / 0 >>> c = Context() >>> c.traps[InvalidOperation] = 0 >>> print(c.flags[InvalidOperation]) 0 >>> c.divide(Decimal(0), Decimal(0)) Decimal('NaN') >>> c.traps[InvalidOperation] = 1 >>> print(c.flags[InvalidOperation]) 1 >>> c.flags[InvalidOperation] = 0 >>> print(c.flags[InvalidOperation]) 0 >>> print(c.divide(Decimal(0), Decimal(0))) Traceback (most recent call last): ... ... ... decimal.InvalidOperation: 0 / 0 >>> print(c.flags[InvalidOperation]) 1 >>> c.flags[InvalidOperation] = 0 >>> c.traps[InvalidOperation] = 0 >>> print(c.divide(Decimal(0), Decimal(0))) NaN >>> print(c.flags[InvalidOperation]) 1 >>> �Decimal�Context� DecimalTuple�DefaultContext� BasicContext�ExtendedContext�DecimalException�Clamped�InvalidOperation�DivisionByZero�Inexact�Rounded� Subnormal�Overflow� Underflow�FloatOperation�DivisionImpossible�InvalidContext�ConversionSyntax�DivisionUndefined� ROUND_DOWN� ROUND_HALF_UP�ROUND_HALF_EVEN� ROUND_CEILING� ROUND_FLOOR�ROUND_UP�ROUND_HALF_DOWN� ROUND_05UP� setcontext� getcontext� localcontext�MAX_PREC�MAX_EMAX�MIN_EMIN� MIN_ETINY� HAVE_THREADSZdecimalz1.70z2.4.2� N)� namedtuplezsign digits exponentc G s | S )N� )�argsr' r' �"/usr/lib64/python3.6/_pydecimal.py�<lambda>� s r* T� �? � l ��N�Zoi@�Tc @ s e Zd ZdZdd� ZdS )r a1 Base exception class. Used exceptions derive from this. If an exception derives from another exception besides this (such as Underflow (Inexact, Rounded, Subnormal) that indicates that it is only called if the others are present. This isn't actually used for anything, though. handle -- Called when context._raise_error is called and the trap_enabler is not set. First argument is self, second is the context. More arguments can be given, those being after the explanation in _raise_error (For example, context._raise_error(NewError, '(-x)!', self._sign) would call NewError().handle(context, self._sign).) To define a new exception, it should be sufficient to have it derive from DecimalException. c G s d S )Nr' )�self�contextr( r' r' r) �handle� s zDecimalException.handleN)�__name__� __module__� __qualname__�__doc__r0 r' r' r' r) r � s c @ s e Zd ZdZdS )r a) Exponent of a 0 changed to fit bounds. This occurs and signals clamped if the exponent of a result has been altered in order to fit the constraints of a specific concrete representation. This may occur when the exponent of a zero result would be outside the bounds of a representation, or when a large normal number would have an encoded exponent that cannot be represented. In this latter case, the exponent is reduced to fit and the corresponding number of zero digits are appended to the coefficient ("fold-down").

This occurs and signals overflow if the adjusted exponent of a result (from a conversion or from an operation that is not an attempt to divide by zero), after rounding, would be greater than the largest value that can be handled by the implementation (the value Emax). The result depends on the rounding mode: For round-half-up and round-half-even (and for round-half-down and round-up, if implemented), the result of the operation is [sign,inf], where sign is the sign of the intermediate result. For round-down, the result is the largest finite number that can be represented in the current precision, with the sign of the intermediate result. For round-ceiling, the result is the same as for round-down if the sign of the intermediate result is 1, or is [0,inf] otherwise. For round-floor, the result is the same as for round-down if the sign of the intermediate result is 0, or is [1,inf] otherwise. In all cases, Inexact and Rounded will also be raised. c G s� |j ttttfkrt| S |dkrR|j tkr4t| S t|d|j |j |j d �S |dkr�|j t krlt| S t|d|j |j |j d �S d S )Nr% �9r- ) �roundingr r r r r< r r6 �prec�Emaxr )r. r/ r= r( r' r' r) r0 s s zOverflow.handleN)r1 r2 r3 r4 r0 r' r' r' r) r ] s c @ s e Zd ZdZdS )r ax Numerical underflow with result rounded to 0. This occurs and signals underflow if a result is inexact and the adjusted exponent of the result would be smaller (more negative) than the smallest value that can be handled by the implementation (the value Emin). That is, the result is both inexact and subnormal. The result after an underflow will be a subnormal number rounded, if necessary, so that its exponent is not less than Etiny. This may result in 0 with the sign of the intermediate result and an exponent of Etiny. In all cases, Inexact, Rounded, and Subnormal will also be raised.

If the signal is not trapped (default), mixing floats and Decimals is permitted in the Decimal() constructor, context.create_decimal() and all comparison operators. Both conversion and comparisons are exact. Any occurrence of a mixed operation is silently recorded by setting FloatOperation in the context flags. Explicit conversions with Decimal.from_float() or context.create_decimal_from_float() do not set the flag. Otherwise (the signal is trapped), only equality comparisons and explicit conversions are silent. All other mixed operations raise FloatOperation.

With two arguments, compute self**other. With three arguments, compute (self**other) % modulo. For the three argument form, the following restrictions on the arguments hold: - all three arguments must be integral - other must be nonnegative - either self or other (or both) must be nonzero - modulo must be nonzero and must have at most p digits, where p is the context precision. If any of these restrictions is violated the InvalidOperation flag is raised. The result of pow(self, other, modulo) is identical to the result that would be obtained by computing (self**other) % modulo with unbounded precision, but is computed more efficiently.

The min_width keyword argument gives the minimum length of the result, which will be padded on the left with zeros if necessary. If necessary, the zero padding adds an extra '0' on the left to avoid a leading thousands separator.

Unless explicitly stated otherwise, the description below is true both for AIFF-C files and AIFF files. An AIFF-C file has the following structure. +-----------------+ | FORM | +-----------------+ | <size> | +----+------------+ | | AIFC | | +------------+ | | <chunks> | | | . | | | . | | | . | +----+------------+ An AIFF file has the string "AIFF" instead of "AIFC". A chunk consists of an identifier (4 bytes) followed by a size (4 bytes, big endian order), followed by the data. The size field does not include the size of the 8 byte header. The following chunk types are recognized. FVER <version number of AIFF-C defining document> (AIFF-C only). MARK <# of markers> (2 bytes) list of markers: <marker ID> (2 bytes, must be > 0) <position> (4 bytes) <marker name> ("pstring") COMM <# of channels> (2 bytes) <# of sound frames> (4 bytes) <size of the samples> (2 bytes) <sampling frequency> (10 bytes, IEEE 80-bit extended floating point) in AIFF-C files only: <compression type> (4 bytes) <human-readable version of compression type> ("pstring") SSND <offset> (4 bytes, not used by this program) <blocksize> (4 bytes, not used by this program) <sound data> A pstring consists of 1 byte length, a string of characters, and 0 or 1 byte pad to make the total length even. Usage. Reading AIFF files: f = aifc.open(file, 'r') where file is either the name of a file or an open file pointer. The open file pointer must have methods read(), seek(), and close(). In some types of audio files, if the setpos() method is not used, the seek() method is not necessary. This returns an instance of a class with the following public methods: getnchannels() -- returns number of audio channels (1 for mono, 2 for stereo) getsampwidth() -- returns sample width in bytes getframerate() -- returns sampling frequency getnframes() -- returns number of audio frames getcomptype() -- returns compression type ('NONE' for AIFF files) getcompname() -- returns human-readable version of compression type ('not compressed' for AIFF files) getparams() -- returns a namedtuple consisting of all of the above in the above order getmarkers() -- get the list of marks in the audio file or None if there are no marks getmark(id) -- get mark with the specified id (raises an error if the mark does not exist) readframes(n) -- returns at most n frames of audio rewind() -- rewind to the beginning of the audio stream setpos(pos) -- seek to the specified position tell() -- return the current position close() -- close the instance (make it unusable) The position returned by tell(), the position given to setpos() and the position of marks are all compatible and have nothing to do with the actual position in the file. The close() method is called automatically when the class instance is destroyed. Writing AIFF files: f = aifc.open(file, 'w') where file is either the name of a file or an open file pointer. The open file pointer must have methods write(), tell(), seek(), and close(). This returns an instance of a class with the following public methods: aiff() -- create an AIFF file (AIFF-C default) aifc() -- create an AIFF-C file setnchannels(n) -- set the number of channels setsampwidth(n) -- set the sample width setframerate(n) -- set the frame rate setnframes(n) -- set the number of frames setcomptype(type, name) -- set the compression type and the human-readable compression type setparams(tuple) -- set all parameters at once setmark(id, pos, name) -- add specified mark to the list of marks tell() -- return current position in output file (useful in combination with setmark()) writeframesraw(data) -- write audio frames without pathing up the file header writeframes(data) -- write audio frames and patch up the file header close() -- patch up the file header and close the output file You should set the parameters before the first writeframesraw or writeframes. The total number of frames does not need to be set, but when it is set to the correct value, the header does not have to be patched up. It is best to first set all parameters, perhaps possibly the compression type, and then write audio frames using writeframesraw. When all frames have been written, either call writeframes(b'') or close() to patch up the sizes in the header. Marks can be added anytime. If there are any marks, you must call close() after all frames have been written. The close() method is called automatically when the class instance is destroyed. When a file is opened with the extension '.aiff', an AIFF file is written, otherwise an AIFF-C file is written. This default can be changed by calling aiff() or aifc() before the first writeframes or writeframesraw. � N�Error�open�openfpc @ s e Zd ZdS )r N)�__name__� __module__� __qualname__� r r �

functions corresponding to the intrinsic operators of Python. For example, operator.add(x, y) is equivalent to the expression x+y.

When not given, this defaults to the PEP 3147/PEP 488 location. :param dfile: Purported file name, i.e. the file name that shows up in error messages. Defaults to the source file name. :param doraise: Flag indicating whether or not an exception should be raised when a compile error is found. If an exception occurs and this flag is set to False, a string indicating the nature of the exception will be printed, and the function will return to the caller. If an exception occurs and this flag is set to True, a PyCompileError exception will be raised. :param optimize: The optimization level for the compiler. Valid values are -1, 0, 1 and 2. A value of -1 means to use the optimization level of the current interpreter, as given by -O command line options. :return: Path to the resulting byte compiled file. Note that it isn't necessary to byte-compile Python modules for execution efficiency -- Python itself byte-compiles a module when it is loaded, and if it can, writes out the bytecode to the corresponding .pyc file. However, if a Python installation is shared between users, it is a good idea to byte-compile all modules upon installation, since other users may not be able to write in the source directories, and thus they won't be able to write the .pyc file, and then they would be byte-compiling every module each time it is loaded. This can slow down program start-up considerably. See compileall.py for a script/module that uses this module to byte-compile all installed files (or all files in selected directories). Do note that FileExistsError is raised if cfile ends up pointing at a non-regular file or symlink. Because the compilation uses a file renaming, the resulting file would be regular and thus not the same type of file as it was previously. Nr r r )� optimizationzc{} is a symlink and will be changed into a regular file if import writes a byte-compiled file to itzk{} is a non-regular file and will be changed into a regular one if import writes a byte-compiled file to itz <py_compile>)� _optimize� �mtime�size) � importlib�util�cache_from_source�os�path�islink�FileExistsError�format�exists�isfile� machinery�SourceFileLoader�get_data�source_to_coder r � __class__�sys�stderr�writer �dirname�makedirs� path_stats�_bootstrap_external�_code_to_bytecode� _calc_mode� _write_atomic)r �cfile�dfile�doraise�optimizer r �loader� source_bytes�code�err�py_excr4 � source_stats�bytecode�moder r r r A sF ) c C s" | dkrt jdd� } d}| dgkr�x�t jj� }|s6P |jd�}yt|dd� W q& tk r� } z d}t jjd|j � W Y dd}~X q& t k r� } zd}t jjd| � W Y dd}~X q&X q&W nZxX| D ]P}yt|dd� W q� tk �r } z d}t jjd|j � W Y dd}~X q�X q�W |S ) a� Compile several source files.

This method is used both when an enum class is given a value to match to an enumeration member (i.e. Color(3)) and for the functional API (i.e. Color = Enum('Color', names='RED GREEN BLUE')). When used for the functional API: `value` will be the name of the new class. `names` should be either a string of white-space/comma delimited names (values will start at `start`), or an iterator/mapping of name, value pairs. `module` should be set to the module this class is being created in; if it is not set, an attempt to find that module will be made, but if it fails the class will not be picklable. `qualname` should be set to the actual location this class can be found at in its module; by default it is set to the global scope. If this is not correct, unpickling will fail in some circumstances. `type`, if set, will be mixed in as the first base class.

other color systems. This modules provides two functions for each color system ABC: rgb_to_abc(r, g, b) --> a, b, c abc_to_rgb(a, b, c) --> r, g, b All inputs and outputs are triples of floats in the range [0.0...1.0] (with the exception of I and Q, which covers a slightly larger range). Inputs outside the valid range may cause exceptions or invalid outputs.

On Unix, it supports IP (Internet Protocol) and Unix domain sockets. On other systems, it only supports IP. Functions specific for a socket are available as methods of the socket object. Functions: socket() -- create a new socket object socketpair() -- create a pair of new socket objects [*] fromfd() -- create a socket object from an open file descriptor [*] fromshare() -- create a socket object from data received from socket.share() [*] gethostname() -- return the current hostname gethostbyname() -- map a hostname to its IP number gethostbyaddr() -- map an IP number or hostname to DNS info getservbyname() -- map a service name and a protocol name to a port number getprotobyname() -- map a protocol name (e.g. 'tcp') to a number ntohs(), ntohl() -- convert 16, 32 bit int from network to host byte order htons(), htonl() -- convert 16, 32 bit int from host to network byte order inet_aton() -- convert IP addr string (123.45.67.89) to 32-bit packed format inet_ntoa() -- convert 32-bit packed format IP to string (123.45.67.89) socket.getdefaulttimeout() -- get the default timeout value socket.setdefaulttimeout() -- set the default timeout value create_connection() -- connects to an address, with an optional timeout and optional source address. [*] not available on all platforms! Special objects: SocketType -- type object for socket objects error -- exception raised for I/O errors has_ipv6 -- boolean value indicating if IPv6 is supported IntEnum constants: AF_INET, AF_UNIX -- socket domains (first argument to socket() call) SOCK_STREAM, SOCK_DGRAM, SOCK_RAW -- socket types (second argument) Integer constants: Many other constants may be defined; these may be used in calls to the setsockopt() and getsockopt() methods. � N)�*)�IntEnum�IntFlag�EBADF� �EAGAIN� � EWOULDBLOCK�fromfd�getfqdn�create_connection� AddressFamily� SocketKindc C s | j � o| jd�S )NZAF_)�isupper� startswith)�C� r � /usr/lib64/python3.6/socket.py�<lambda>L s r c C s | j � o| jd�S )NZSOCK_)r r )r r r r r Q s ZMsgFlagc C s | j � o| jd�S )NZMSG_)r r )r r r r r V s Z AddressInfoc C s | j � o| jd�S )NZAI_)r r )r r r r r [ s z 127.0.0.1z::1c C s" y|| �S t k r | S X dS )z{Convert a numeric family value to an IntEnum member.

If os.sendfile() is not available (e.g. Windows) or file is not a regular file socket.send() will be used instead. *offset* tells from where to start reading the file. If specified, *count* is the total number of bytes to transmit as opposed to sending the file until EOF is reached. File position is updated on return or also in case of error in which case file.tell() can be used to figure out the number of bytes which were sent. The socket must be of SOCK_STREAM type.

Convenience function. Connect to *address* (a 2-tuple ``(host, port)``) and return the socket object. Passing the optional *timeout* parameter will set the timeout on the socket instance before attempting to connect. If no *timeout* is supplied, the global default timeout setting returned by :func:`getdefaulttimeout` is used. If *source_address* is set it must be a tuple of (host, port) for the socket to bind as a source address before making the connection. A host of '' or port 0 tells the OS to use the default.

Translate the host/port argument into a sequence of 5-tuples that contain all the necessary arguments for creating a socket connected to that service. host is a domain name, a string representation of an IPv4/v6 address or None. port is a string service name such as 'http', a numeric port number or None. By passing None as the value of host and port, you can pass NULL to the underlying C API. The family, type and proto arguments can be optionally specified in order to narrow the list of addresses returned. Passing zero as a value for each of these arguments selects the full range of results. )r" r� �appendr r r ) r� r� r% r& r' �flagsZaddrlistr� r� r� r� r� r r r r� � s r� )r )r- )r r r r ).r� r" r_ �sysrM rd �enumr r �errno� ImportErrorr/ r r r �__all__�extend�_get_exports_list�_convertr r� r� r r Z _realsocket�platform�lowerr r r� � Exceptionr r rc r� rw r� r� r� r� rL r �objectr� r r� r r r r �<module>/ s� C $ u ' mailcap.cpython-36.opt-1.pyc 0000644 00000016053 15246273046 0011555 0 ustar 00 3 ��ik# � @ s� d Z ddlZddlZddlZddgZdd� Zejd�jZG dd � d e �Z d d� Z d d � Z d d� Z dd� Zdd� Zdd� Zddg fdd�Zd#dd�Zg fdd�Zd d � Zd d � Zd d!� Zed"kr�e� dS )$z%Mailcap file handling.

Typical use is: import fileinput for line in fileinput.input(): process(line) This iterates over the lines of all files listed in sys.argv[1:], defaulting to sys.stdin if the list is empty. If a filename is '-' it is also replaced by sys.stdin. To specify an alternative list of filenames, pass it as the argument to input(). A single file name is also allowed. Functions filename(), lineno() return the filename and cumulative line number of the line that has just been read; filelineno() returns its line number in the current file; isfirstline() returns true iff the line just read is the first line of its file; isstdin() returns true iff the line was read from sys.stdin. Function nextfile() closes the current file so that the next iteration will read the first line from the next file (if any); lines not read from the file will not count towards the cumulative line count; the filename is not changed until after the first line of the next file has been read. Function close() closes the sequence. Before any lines have been read, filename() returns None and both line numbers are zero; nextfile() has no effect. After all lines have been read, filename() and the line number functions return the values pertaining to the last line read; nextfile() has no effect. All files are opened in text mode by default, you can override this by setting the mode parameter to input() or FileInput.__init__(). If an I/O error occurs during opening or reading a file, the OSError exception is raised. If sys.stdin is used more than once, the second and further use will return no lines, except perhaps for interactive use, or if it has been explicitly reset (e.g. using sys.stdin.seek(0)). Empty files are opened and immediately closed; the only time their presence in the list of filenames is noticeable at all is when the last file opened is empty. It is possible that the last line of a file doesn't end in a newline character; otherwise lines are returned including the trailing newline. Class FileInput is the implementation; its methods filename(), lineno(), fileline(), isfirstline(), isstdin(), nextfile() and close() correspond to the functions in the module. In addition it has a readline() method which returns the next input line, and a __getitem__() method which implements the sequence behavior. The sequence must be accessed in strictly sequential order; sequence access and readline() cannot be mixed. Optional in-place filtering: if the keyword argument inplace=1 is passed to input() or to the FileInput constructor, the file is moved to a backup file and standard output is directed to the input file. This makes it possible to write a filter that rewrites its input file in place. If the keyword argument backup=".<some extension>" is also given, it specifies the extension for the backup file, and the backup file remains around; by default, the extension is ".bak" and it is deleted when the output file is closed. In-place filtering is disabled when standard input is read. XXX The current implementation does not work for MS-DOS 8+3 filesystems.

Usage:: T = TypeVar('T') # Can be anything A = TypeVar('A', str, bytes) # Must be str or bytes Type variables exist primarily for the benefit of static type checkers. They serve as the parameters for generic types as well as for generic function definitions. See class Generic for more information on generic types. Generic functions work as follows: def repeat(x: T, n: int) -> List[T]: '''Return a list containing n references to x.''' return [x]*n def longest(x: A, y: A) -> A: '''Return the longest of two strings.''' return x if len(x) >= len(y) else y The latter example's signature is essentially the overloading of (str, str) -> str and (bytes, bytes) -> bytes. Also note that if the arguments are instances of some subclass of str, the return type is still plain str. At runtime, isinstance(x, T) and issubclass(C, T) will raise TypeError. Type variables defined with covariant=True or contravariant=True can be used do declare covariant or contravariant generic types. See PEP 484 for more details. By default generic types are invariant in all type variables. Type variables can be introspected. e.g.: T.__name__ == 'T' T.__constraints__ == () T.__covariant__ == False T.__contravariant__ = False A.__constraints__ == (str, bytes) rA � __bound__r� � __covariant__�__contravariant__NF)�bound� covariant� contravariantc s� t � j|f|�|||d�� || _|r2|r2td��t|�| _t|�| _|rZ|d k rZtd��|rrt|�dkrrtd��d� t � fdd�|D ��| _ |r�t |d �| _ nd | _ d S ) N)r� r� r� z"Bivariant types are not supported.z-Constraints cannot be combined with bound=...rK z"A single constraint is not allowedz:TypeVar(name, constraint, ...): constraints must be types.c 3 s | ]}t |� �V qd S )N)r} )�.0r� )r� rC rD � <genexpr> s z#TypeVar.__init__.<locals>.<genexpr>zBound must be a type.) rT r^ rA � ValueError�boolr� r� rP rk rn r� r} r� )r[ rW r� r� r� Z constraints)rZ )r� rD r^ � s zTypeVar.__init__c C s | |kr|j | � d S )N)�append)r[ rb rC rC rD rc s zTypeVar._get_type_varsc C s& | j r d}n| jrd}nd}|| j S )N�+�-�~)r� r� rA )r[ �prefixrC rC rD rf s zTypeVar.__repr__c C s t d��d S )Nz0Type variables cannot be used with isinstance().)rP )r[ �instancerC rC rD r� s zTypeVar.__instancecheck__c C s t d��d S )Nz0Type variables cannot be used with issubclass().)rP )r[ rV rC rC rD r� s zTypeVar.__subclasscheck__)rA r� r� r� r� ) rA rd r@ rg rq r^ rc rf r� r� ri rC rC )rZ rD r � s ( �T�KT�VT�T_co)r� �V_co�VT_co�T_contra)r� c C sd |dkr g }t | d�r0t| ttf�r0| j||�S t| t�r`x$t|�D ]\}}| |krD|| S qDW | S )z�An internal helper function: replace arg if it is a type variable found in tvars with corresponding substitution from args or with corresponding substitution sub-tree if arg is a generic type.

This is often the same as obj.__annotations__, but it handles forward references encoded as string literals, and if necessary adds Optional[t] if a default value equal to None is set. The argument may be a module, class, method, or function. The annotations are returned as a dictionary. For classes, annotations include also inherited members. TypeError is raised if the argument is not of a type that can contain annotations, and an empty dictionary is returned if no annotations are present. BEWARE -- the behavior of globalns and localns is counterintuitive (unless you are familiar with how eval() and exec() work). The search order is locals first, then globals. - If no dict arguments are passed, an attempt is made to use the globals from obj (or the respective module's globals for classes), and these are also used as the locals. If the object does not appear to have globals, an empty dictionary is used. - If one dict argument is passed, it is used for both globals and locals. - If two dict arguments are passed, they specify globals and locals, respectively. �__no_type_check__N�__annotations__� __globals__z1{!r} is not a module, class, method, or function.)r� rl ro �reversedr� r> �modulesrd r �get�itemsrm rG ra r� � ModuleType�_allowed_typesrP r r r� r ) r� r_ r` Zhintsr� Z base_globalsZannrW r� r rC rC rD r7 � sV c C s� t | t�r|| jj� }x0| jj� D ]"\}}|| j| f kr |j|� q W x4|j� D ](}t |tj �rfd|_ t |t�rPt |� qPW y d| _ W n t k r� Y nX | S )aI Decorator to indicate that annotations are not type hints.

An audio file consists of a header followed by the data. The structure of the header is as follows. +---------------+ | magic word | +---------------+ | header size | +---------------+ | data size | +---------------+ | encoding | +---------------+ | sample rate | +---------------+ | # of channels | +---------------+ | info | | | +---------------+ The magic word consists of the 4 characters '.snd'. Apart from the info field, all header fields are 4 bytes in size. They are all 32-bit unsigned integers encoded in big-endian byte order. The header size really gives the start of the data. The data size is the physical size of the data. From the other parameters the number of frames can be calculated. The encoding gives the way in which audio samples are encoded. Possible values are listed below. The info field currently consists of an ASCII string giving a human-readable description of the audio file. The info field is padded with NUL bytes to the header size. Usage. Reading audio files: f = sunau.open(file, 'r') where file is either the name of a file or an open file pointer. The open file pointer must have methods read(), seek(), and close(). When the setpos() and rewind() methods are not used, the seek() method is not necessary. This returns an instance of a class with the following public methods: getnchannels() -- returns number of audio channels (1 for mono, 2 for stereo) getsampwidth() -- returns sample width in bytes getframerate() -- returns sampling frequency getnframes() -- returns number of audio frames getcomptype() -- returns compression type ('NONE' or 'ULAW') getcompname() -- returns human-readable version of compression type ('not compressed' matches 'NONE') getparams() -- returns a namedtuple consisting of all of the above in the above order getmarkers() -- returns None (for compatibility with the aifc module) getmark(id) -- raises an error since the mark does not exist (for compatibility with the aifc module) readframes(n) -- returns at most n frames of audio rewind() -- rewind to the beginning of the audio stream setpos(pos) -- seek to the specified position tell() -- return the current position close() -- close the instance (make it unusable) The position returned by tell() and the position given to setpos() are compatible and have nothing to do with the actual position in the file. The close() method is called automatically when the class instance is destroyed. Writing audio files: f = sunau.open(file, 'w') where file is either the name of a file or an open file pointer. The open file pointer must have methods write(), tell(), seek(), and close(). This returns an instance of a class with the following public methods: setnchannels(n) -- set the number of channels setsampwidth(n) -- set the sample width setframerate(n) -- set the frame rate setnframes(n) -- set the number of frames setcomptype(type, name) -- set the compression type and the human-readable compression type setparams(tuple)-- set all parameters at once tell() -- return current position in output file writeframesraw(data) -- write audio frames without pathing up the file header writeframes(data) -- write audio frames and patch up the file header close() -- patch up the file header and close the output file You should set the parameters before the first writeframesraw or writeframes. The total number of frames does not need to be set, but when it is set to the correct value, the header does not have to be patched up. It is best to first set all parameters, perhaps possibly the compression type, and then write audio frames using writeframesraw. When all frames have been written, either call writeframes(b'') or close() to patch up the sizes in the header.

The basic algorithm predates, and is a little fancier than, an algorithm published in the late 1980's by Ratcliff and Obershelp under the hyperbolic name "gestalt pattern matching". The basic idea is to find the longest contiguous matching subsequence that contains no "junk" elements (R-O doesn't address junk). The same idea is then applied recursively to the pieces of the sequences to the left and to the right of the matching subsequence. This does not yield minimal edit sequences, but does tend to yield matches that "look right" to people. SequenceMatcher tries to compute a "human-friendly diff" between two sequences. Unlike e.g. UNIX(tm) diff, the fundamental notion is the longest *contiguous* & junk-free matching subsequence. That's what catches peoples' eyes. The Windows(tm) windiff has another interesting notion, pairing up elements that appear uniquely in each sequence. That, and the method here, appear to yield more intuitive difference reports than does diff. This method appears to be the least vulnerable to synching up on blocks of "junk lines", though (like blank lines in ordinary text files, or maybe "<P>" lines in HTML files). That may be because this is the only method of the 3 that has a *concept* of "junk" <wink>. Example, comparing two strings, and considering blanks to be "junk": >>> s = SequenceMatcher(lambda x: x == " ", ... "private Thread currentThread;", ... "private volatile Thread currentThread;") >>> .ratio() returns a float in [0, 1], measuring the "similarity" of the sequences. As a rule of thumb, a .ratio() value over 0.6 means the sequences are close matches: >>> print(round(s.ratio(), 3)) 0.866 >>> If you're only interested in where the sequences match, .get_matching_blocks() is handy: >>> for block in s.get_matching_blocks(): ... print("a[%d] and b[%d] match for %d elements" % block) a[0] and b[0] match for 8 elements a[8] and b[17] match for 21 elements a[29] and b[38] match for 0 elements Note that the last tuple returned by .get_matching_blocks() is always a dummy, (len(a), len(b), 0), and this is the only case in which the last tuple element (number of elements matched) is 0. If you want to know how to change the first sequence into the second, use .get_opcodes(): >>> for opcode in s.get_opcodes(): ... print("%6s a[%d:%d] b[%d:%d]" % opcode) equal a[0:8] b[0:8] insert a[8:8] b[8:17] equal a[8:29] b[17:38] See the Differ class for a fancy human-friendly file differencer, which uses SequenceMatcher both to compare sequences of lines, and to compare sequences of characters within similar (near-matching) lines. See also function get_close_matches() in this module, which shows how simple code building on SequenceMatcher can be used to do useful work. Timing: Basic R-O is cubic time worst case and quadratic time expected case. SequenceMatcher is quadratic time for the worst case and has expected-case behavior dependent in a complicated way on how many elements the sequences have in common; best case time is linear. Methods: __init__(isjunk=None, a='', b='') Construct a SequenceMatcher. set_seqs(a, b) Set the two sequences to be compared. set_seq1(a) Set the first sequence to be compared. set_seq2(b) Set the second sequence to be compared. find_longest_match(alo, ahi, blo, bhi) Find longest matching block in a[alo:ahi] and b[blo:bhi]. get_matching_blocks() Return list of triples describing matching subsequences. get_opcodes() Return list of 5-tuples describing how to turn a into b. ratio() Return a measure of the sequences' similarity (float in [0,1]). quick_ratio() Return an upper bound on .ratio() relatively quickly. real_quick_ratio() Return an upper bound on ratio() very quickly. N� Tc C s( || _ d | _| _|| _| j||� dS )a! Construct a SequenceMatcher. Optional arg isjunk is None (the default), or a one-argument function that takes a sequence element and returns true iff the element is junk. None is equivalent to passing "lambda x: 0", i.e. no elements are considered to be junk. For example, pass lambda x: x in " \t" if you're comparing lines as sequences of characters, and don't want to synch up on blanks or hard tabs. Optional arg a is the first of two sequences to be compared. By default, an empty string. The elements of a must be hashable. See also .set_seqs() and .set_seq1(). Optional arg b is the second of two sequences to be compared. By default, an empty string. The elements of b must be hashable. See also .set_seqs() and .set_seq2(). Optional arg autojunk should be set to False to disable the "automatic junk heuristic" that treats popular elements as junk (see module documentation for more information).

If isjunk is not defined: Return (i,j,k) such that a[i:i+k] is equal to b[j:j+k], where alo <= i <= i+k <= ahi blo <= j <= j+k <= bhi and for all (i',j',k') meeting those conditions, k >= k' i <= i' and if i == i', j <= j' In other words, of all maximal matching blocks, return one that starts earliest in a, and of all those maximal matching blocks that start earliest in a, return the one that starts earliest in b. >>> s = SequenceMatcher(None, " abcd", "abcd abcd") >>> s.find_longest_match(0, 5, 0, 9) Match(a=0, b=4, size=5) If isjunk is defined, first the longest matching block is determined as above, but with the additional restriction that no junk element appears in the block. Then that block is extended as far as possible by matching (only) junk elements on both sides. So the resulting block never matches on junk except as identical junk happens to be adjacent to an "interesting" match. Here's the same example as before, but considering blanks to be junk. That prevents " abcd" from matching the " abcd" at the tail end of the second sequence directly. Instead only the "abcd" can match, and matches the leftmost "abcd" in the second sequence: >>> s = SequenceMatcher(lambda x: x==" ", " abcd", "abcd abcd") >>> s.find_longest_match(0, 5, 0, 9) Match(a=1, b=0, size=4) If no blocks match, return (alo, blo, 0). >>> s = SequenceMatcher(None, "ab", "c") >>> s.find_longest_match(0, 2, 0, 1) Match(a=0, b=0, size=0) r r% )r r r& r+ � __contains__�range�getr )r �alo�ahi�blo�bhir r r& ZisbjunkZbestiZbestjZbestsizeZj2lenZnothingr0 Zj2lengetZnewj2len�j�kr r r �find_longest_matchP sB 8 $ " z"SequenceMatcher.find_longest_matchc C s� | j dk r| j S t| j�t| j� }}d|d|fg}g }x�|r�|j� \}}}}| j||||� \} } } } | r:|j| � || k r�|| k r�|j|| || f� | | |k r:| | |k r:|j| | || | |f� q:W |j� d } }}g }x^|D ]V\}}}| | |k�r || |k�r ||7 }q�|�r2|j| ||f� ||| } }}q�W |�r\|j| ||f� |j||df� tt t j |��| _ | j S )a Return list of triples describing matching subsequences. Each triple is of the form (i, j, n), and means that a[i:i+n] == b[j:j+n]. The triples are monotonically increasing in i and in j.

IOW, adjacent triples never describe adjacent equal blocks. The last triple is a dummy, (len(a), len(b), 0), and is the only triple with n==0. >>> s = SequenceMatcher(None, "abxcd", "abcd") >>> list(s.get_matching_blocks()) [Match(a=0, b=0, size=2), Match(a=3, b=2, size=2), Match(a=5, b=4, size=0)] Nr ) r r. r r �popr= r) �sort�list�mapr �_make)r �la�lbZqueuer r7 r8 r9 r: r0 r; r< �x�i1�j1Zk1Z non_adjacent�i2�j2Zk2r r r �get_matching_blocks� s8 z#SequenceMatcher.get_matching_blocksc C s� | j dk r| j S d }}g | _ }x�| j� D ]�\}}}d}||k rP||k rPd}n||k r^d}n ||k rjd}|r�|j|||||f� || || }}|r,|jd||||f� q,W |S )a[ Return list of 5-tuples describing how to turn a into b.

The tags are strings, with these meanings: 'replace': a[i1:i2] should be replaced by b[j1:j2] 'delete': a[i1:i2] should be deleted. Note that j1==j2 in this case.

Differ uses SequenceMatcher both to compare sequences of lines, and to compare sequences of characters within similar (near-matching) lines. Each line of a Differ delta begins with a two-letter code: '- ' line unique to sequence 1 '+ ' line unique to sequence 2 ' ' line common to both sequences '? ' line not present in either input sequence Lines beginning with '? ' attempt to guide the eye to intraline differences, and were not present in either input sequence. These lines can be confusing if the sequences contain tab characters. Note that Differ makes no claim to produce a *minimal* diff. To the contrary, minimal diffs are often counter-intuitive, because they synch up anywhere possible, sometimes accidental matches 100 pages apart. Restricting synch points to contiguous matches preserves some notion of locality, at the occasional cost of producing a longer diff. Example: Comparing two texts. First we set up the texts, sequences of individual single-line strings ending with newlines (such sequences can also be obtained from the `readlines()` method of file-like objects): >>> text1 = ''' 1. Beautiful is better than ugly. ... 2. Explicit is better than implicit. ... 3. Simple is better than complex. ... 4. Complex is better than complicated. ... '''.splitlines(keepends=True) >>> len(text1) 4 >>> text1[0][-1] '\n' >>> text2 = ''' 1. Beautiful is better than ugly. ... 3. Simple is better than complex. ... 4. Complicated is better than complex. ... 5. Flat is better than nested. ... '''.splitlines(keepends=True) Next we instantiate a Differ object: >>> d = Differ() Note that when instantiating a Differ object we may pass functions to filter out line and character 'junk'. See Differ.__init__ for details. Finally, we compare the two: >>> result = list(d.compare(text1, text2)) 'result' is a list of strings, so let's pretty-print it: >>> from pprint import pprint as _pprint >>> _pprint(result) [' 1.

Flat is better than nested.\n'] As a single multi-line string it looks like this: >>> print(''.join(result), end="") 1. Beautiful is better than ugly. - 2. Explicit is better than implicit. - 3. Simple is better than complex. + 3. Simple is better than complex. ? ++ - 4. Complex is better than complicated. ? ^ ---- ^ + 4. Complicated is better than complex. ? ++++ ^ ^ + 5.

Nc C s || _ || _dS )a� Construct a text differencer, with optional filters. The two optional keyword parameters are for filter functions: - `linejunk`: A function that should accept a single string argument, and return true iff the string is junk. The module-level function `IS_LINE_JUNK` may be used to filter out lines without visible characters, except for at most one splat ('#'). It is recommended to leave linejunk None; the underlying SequenceMatcher class has an adaptive notion of "noise" lines that's better than any static definition the author has ever been able to craft. - `charjunk`: A function that should accept a string of length 1. The module-level function `IS_CHARACTER_JUNK` may be used to filter out whitespace characters (a blank or tab; **note**: bad idea to include newline in this!). Use of IS_CHARACTER_JUNK is recommended.

Each sequence must contain individual single-line strings ending with newlines. Such sequences can be obtained from the `readlines()` method of file-like objects. The delta generated also consists of newline- terminated strings, ready to be printed as-is via the writeline() method of a file-like object.

Unified diffs are a compact way of showing line changes and a few lines of context. The number of context lines is set by 'n' which defaults to three. By default, the diff control lines (those with ---, +++, or @@) are created with a trailing newline. This is helpful so that inputs created from file.readlines() result in diffs that are suitable for file.writelines() since both the inputs and outputs have trailing newlines. For inputs that do not have trailing newlines, set the lineterm argument to "" so that the output will be uniformly newline free. The unidiff format normally has a header for filenames and modification times. Any or all of these may be specified using strings for 'fromfile', 'tofile', 'fromfiledate', and 'tofiledate'. The modification times are normally expressed in the ISO 8601 format. Example: >>> for line in unified_diff('one two three four'.split(), ... 'zero one tree four'.split(), 'Original', 'Current', ...

A selector supports registering file objects to be monitored for specific I/O events. A file object is a file descriptor or any object with a `fileno()` method. An arbitrary object can be attached to the file object, which can be used for example to store context information, a callback, etc. A selector can use various implementations (select(), poll(), epoll()...) depending on the platform. The default `Selector` class uses the most efficient implementation on the current platform. Nc C s t �dS )a3 Register a file object.

Returns a tuple (bits, linkage) which contains information about the bit architecture and the linkage format used for the executable. Both values are returned as strings. Values that cannot be determined are returned as given by the parameter presets. If bits is given as '', the sizeof(pointer) (or sizeof(long) on Python version < 1.5.2) is used as indicator for the supported pointer size. The function relies on the system's "file" command to do the actual work. This is available on most if not all Unix platforms. On some non-Unix platforms where the "file" command does not exist and the executable is set to the Python interpreter binary defaults from _default_architecture are used. r N�Prd � �bitr r4 z32-bit�32bitZN32Zn32bitz64-bitr� ZELFZPEr� r� ZCOFFzMS-DOSr� ) �structZcalcsize�errorr� r� r� r4 r� �_default_architecture)r4 �bits�linkager� �sizeZfileoutr rd r r r � architectureB sL r� � uname_resultz-system node release version machine processorc C s� d} t dk rt S d}ytj� \}}}}}W n tk rB d} Y nX | sdttd|||||f�� �r�| r�tj}d}d}t� }d}d}|dkr�t � \}}}} |r�|r�d}|s�dtj kr�tj j dd�}ntj j dd�}|s�tj j d|�}|�r<t |�\}}}|d k�rd }n4|d k�r<|d k�r<d }d |dd � k�r8d}nd}|d k�rf|�s`|dk�r\d}nd}d }n8|dd� dk�r�t � \}} } } d}dj| �}|�s�| }|dk�r | �s�|dk�r�|}d}y ddl} W n tk �r� Y n&X | jdd�\}}|dk�rd}nd}|�std d�}|d k�r(d}|d k�r6d}|d k�rDd}|d k�rRd}|d k�r`d}|d k�rnd}|d k�r�|d k�r�d }d}t||||||�a t S ) an Fairly portable uname interface.

However, due to malformed data, it may not. We don't want an all or nothing approach, so we allow for small variations in this number. 1) build a table of the frequency of each character on every line. 2) build a table of frequencies of this frequency (meta-frequency?), e.g. 'x occurred 5 times in 10 rows, 6 times in 1000 rows, 7 times in 2 rows' 3) use the mode of the meta-frequency to determine the /expected/ frequency for that character 4) find out how often the character actually meets that goal 5) the character that best meets its goal is the delimiter For performance reasons, the data is evaluated in chunks, so it can try and evaluate the smallest portion of the data possible, evaluating additional chunks as necessary.

Usage: %(program)s [options] [localhost:localport [remotehost:remoteport]] Options: --nosetuid -n This program generally tries to setuid `nobody', unless this flag is set. The setuid call will fail if this program is not run as root (in which case, use this flag). --version -V Print the version number and exit. --class classname -c classname Use `classname' as the concrete SMTP proxy class. Uses `PureProxy' by default. --size limit -s limit Restrict the total size of the incoming message to "limit" number of bytes via the RFC 1870 SIZE extension. Defaults to 33554432 bytes. --smtputf8 -u Enable the SMTPUTF8 extension and behave as an RFC 6531 smtp proxy. --debug -d Turn on debugging prints. --help -h Print this message and exit. Version: %(__version__)s If localhost is not given then `localhost' is used, and if localport is not given then 8025 is used. If remotehost is not given then `localhost' is used, and if remoteport is not given, then 25 is used. � N)�warn)� get_addr_spec�get_angle_addr� SMTPChannel� SMTPServer�DebuggingServer� PureProxy�

socket connection to our smtp port. mailfrom is the raw address the client claims the message is coming from. rcpttos is a list of raw addresses the client wishes to deliver the message to. data is a string containing the entire full text of the message, headers (if supplied) and all. It has been `de-transparencied' according to RFC 821, Section 4.5.2. In other words, a line containing a `.' followed by other text has had the leading dot removed. kwargs is a dictionary containing additional information. It is empty if decode_data=True was given as init parameter, otherwise it will contain the following keys: 'mail_options': list of parameters to the mail command. All elements are uppercase strings.

This module tries to capture the various aspects of defining a server: For socket-based servers: - address family: - AF_INET{,6}: IP (Internet Protocol) sockets (default) - AF_UNIX: Unix domain sockets - others, e.g. AF_DECNET are conceivable (see <socket.h> - socket type: - SOCK_STREAM (reliable stream, e.g. TCP) - SOCK_DGRAM (datagrams, e.g. UDP) For request-based servers (including socket-based): - client address verification before further looking at the request (This is actually a hook for any processing that needs to look at the request before anything else, e.g. logging) - how to handle multiple requests: - synchronous (one request is handled at a time) - forking (each request is handled by a new process) - threading (each request is handled by a new thread) The classes in this module favor the server type that is simplest to write: a synchronous TCP/IP server. This is bad class design, but save some typing. (There's also the issue that a deep class hierarchy slows down method lookups.) There are five classes in an inheritance diagram, four of which represent synchronous servers of four types: +------------+ | BaseServer | +------------+ | v +-----------+ +------------------+ | TCPServer |------->| UnixStreamServer | +-----------+ +------------------+ | v +-----------+ +--------------------+ | UDPServer |------->| UnixDatagramServer | +-----------+ +--------------------+ Note that UnixDatagramServer derives from UDPServer, not from UnixStreamServer -- the only difference between an IP and a Unix stream server is the address family, which is simply repeated in both unix server classes. Forking and threading versions of each type of server can be created using the ForkingMixIn and ThreadingMixIn mix-in classes. For instance, a threading UDP server class is created as follows: class ThreadingUDPServer(ThreadingMixIn, UDPServer): pass The Mix-in class must come first, since it overrides a method defined in UDPServer! Setting the various member variables also changes the behavior of the underlying server mechanism. To implement a service, you must derive a class from BaseRequestHandler and redefine its handle() method. You can then run various versions of the service by combining one of the server classes with your request handler class. The request handler class must be different for datagram or stream services. This can be hidden by using the request handler subclasses StreamRequestHandler or DatagramRequestHandler. Of course, you still have to use your head! For instance, it makes no sense to use a forking server if the service contains state in memory that can be modified by requests (since the modifications in the child process would never reach the initial state kept in the parent process and passed to each child). In this case, you can use a threading server, but you will probably have to use locks to avoid two requests that come in nearly simultaneous to apply conflicting changes to the server state. On the other hand, if you are building e.g. an HTTP server, where all data is stored externally (e.g. in the file system), a synchronous class will essentially render the service "deaf" while one request is being handled -- which may be for a very long time if a client is slow to read all the data it has requested. Here a threading or forking server is appropriate. In some cases, it may be appropriate to process part of a request synchronously, but to finish processing in a forked child depending on the request data. This can be implemented by using a synchronous server and doing an explicit fork in the request handler class handle() method. Another approach to handling multiple simultaneous requests in an environment that supports neither threads nor fork (or where these are too expensive or inappropriate for the service) is to maintain an explicit table of partially finished requests and to use a selector to decide which request to work on next (or whether to handle a new incoming request). This is particularly important for stream services where each client can potentially be connected for a long time (if threads or subprocesses cannot be used). Future work: - Standard classes for Sun RPC (which uses either UDP or TCP) - Standard mix-in classes to implement various authentication and encryption schemes XXX Open problems: - What to do with out-of-band data? BaseServer: - split generic "request" functionality out into BaseServer class.

This class is instantiated for each request to be handled. The constructor sets the instance variables request, client_address and server, and then calls the handle() method. To implement a specific service, all you need to do is to derive a class which defines a handle() method. The handle() method can find the request as self.request, the client address as self.client_address, and the server (in case it needs access to per-server information) as self.server. Since a separate instance is created for each request, the handle() method can define other arbitrary instance variables. c C s6 || _ || _|| _| j� z | j� W d | j� X d S )N)r= r> �server�setup�handle�finish)r r= r> rz r r r r � s zBaseRequestHandler.__init__c C s d S )Nr )r r r r r{ � s zBaseRequestHandler.setupc C s d S )Nr )r r r r r| � s zBaseRequestHandler.handlec C s d S )Nr )r r r r r} � s zBaseRequestHandler.finishN)rM rN rO rP r r{ r| r} r r r r r � s c @ s0 e Zd ZdZd ZdZdZdZdd� Zdd � Z dS ) r z4Define self.rfile and self.wfile for stream sockets.rU r NFc C sz | j | _| jd k r | jj| j� | jr:| jjtjtjd� | jj d| j �| _ | j dkrdt | j�| _n| jj d| j �| _d S )NT�rbr �wb)r= Z connectionr1 Z settimeout�disable_nagle_algorithmrW r0 Z IPPROTO_TCPZ TCP_NODELAY�makefile�rbufsize�rfile�wbufsize� _SocketWriter�wfile)r r r r r{ � s zStreamRequestHandler.setupc C sF | j js.y| j j� W n tjk r, Y nX | j j� | jj� d S )N)r� �closed�flushr0 �errorrY r� )r r r r r} s zStreamRequestHandler.finishr^ ) rM rN rO rP r� r� r1 r� r{ r} r r r r r � s c @ s0 e Zd ZdZdd� Zdd� Zdd� Zdd � Zd S ) r� z�Simple writable BufferedIOBase implementation for a socket Does not hold data in a buffer, avoiding any need to call flush().c C s || _ d S )N)�_sock)r Zsockr r r r s z_SocketWriter.__init__c C s dS )NTr )r r r r �writable s z_SocketWriter.writablec C s& | j j|� t|��}|jS Q R X d S )N)r� Zsendall� memoryview�nbytes)r �bZviewr r r �write" s z_SocketWriter.writec C s | j j� S )N)r� rZ )r r r r rZ ' s z_SocketWriter.filenoN)rM rN rO rP r r� r� rZ r r r r r� s r� c @ s e Zd ZdZdd� Zdd� ZdS )r z6Define self.rfile and self.wfile for datagram sockets.c C s2 ddl m} | j\| _| _|| j�| _|� | _d S )Nr )�BytesIO)�ior� r= Zpacketr0 r� r� )r r� r r r r{ . s z DatagramRequestHandler.setupc C s | j j| jj� | j� d S )N)r0 Zsendtor� �getvaluer> )r r r r r} 4 s z DatagramRequestHandler.finishN)rM rN rO rP r{ r} r r r r r * s )%rP � __version__r0 r% rb �errnorF r � ImportErrorZdummy_threadingr� r r3 r �__all__�hasattr�extendr r# ZSelectSelectorr r r r r r r r r r r r r r r r� r r r r r �<module>w s\ n~ X. .- shelve.cpython-36.opt-2.pyc 0000644 00000012273 15246273046 0011436 0 ustar 00 3 \C! � @ s� d dl mZmZ d dlmZ d dlZddddgZG dd � d ej�ZG d d� dej�Z G d d� de �Z G d d� de �Z ddd�Z dS )� )�Pickler� Unpickler)�BytesION�Shelf� BsdDbShelf�DbfilenameShelf�openc @ s4 e Zd Zdd� Ze Z Z Z Z ZZ dd� Z dS )� _ClosedDictc G s t d��d S )Nz!invalid operation on closed shelf)� ValueError)�self�args� r � /usr/lib64/python3.6/shelve.py�closedE s z_ClosedDict.closedc C s dS )Nz<Closed Dictionary>r )r r r r �__repr__I s z_ClosedDict.__repr__N) �__name__� __module__� __qualname__r �__iter__�__len__� __getitem__� __setitem__� __delitem__�keysr r r r r r B s r c @ sx e Zd Zd dd�Zdd� Zdd � Zd d � Zd d d �Zdd� Zdd� Z dd� Z dd� Z dd� Z dd� Z dd� Zd d � ZdS ) r NF�utf-8c C s. || _ |d krd}|| _|| _i | _|| _d S )N� )�dict� _protocol� writeback�cache� keyencoding)r r �protocolr r r r r �__init__T s zShelf.__init__c c s& x | j j� D ]}|j| j�V q W d S )N)r r �decoder )r �kr r r r ^ s zShelf.__iter__c C s t | j�S )N)�lenr )r r r r r b s z Shelf.__len__c C s |j | j�| jkS )N)�encoder r )r �keyr r r � __contains__e s zShelf.__contains__c C s |j | j�| jkr| | S |S )N)r& r r )r r' �defaultr r r �geth s z Shelf.getc C sZ y| j | }W nF tk rT t| j|j| j� �}t|�j� }| jrP|| j |< Y nX |S )N) r �KeyErrorr r r& r r �loadr )r r' �value�fr r r r m s zShelf.__getitem__c C sF | j r|| j|< t� }t|| j�}|j|� |j� | j|j| j �< d S )N) r r r r r �dump�getvaluer r& r )r r' r- r. �pr r r r w s zShelf.__setitem__c C s6 | j |j| j�= y | j|= W n tk r0 Y nX d S )N)r r& r r r+ )r r' r r r r s zShelf.__delitem__c C s | S )Nr )r r r r � __enter__� s zShelf.__enter__c C s | j � d S )N)�close)r �typer- � tracebackr r r �__exit__� s zShelf.__exit__c C sf | j d krd S z0| j� y| j j� W n tk r: Y nX W d y t� | _ W n d | _ Y nX X d S )N)r �syncr3 �AttributeErrorr )r r r r r3 � s z Shelf.closec C s t | d�sd S | j� d S )Nr )�hasattrr3 )r r r r �__del__� s z Shelf.__del__c C sX | j r>| jr>d| _ x | jj� D ]\}}|| |< q W d| _ i | _t| jd�rT| jj� d S )NFTr7 )r r �itemsr9 r r7 )r r' �entryr r r r7 � s z Shelf.sync)NFr )N)r r r r" r r r( r* r r r r2 r6 r3 r: r7 r r r r r M s c @ s> e Zd Zddd�Zdd� Zdd � Zd d � Zd d � Zdd� ZdS )r NF�utf-8c C s t j| ||||� d S )N)r r" )r r r! r r r r r r" � s zBsdDbShelf.__init__c C s0 | j j|�\}}t|�}|j| j�t|�j� fS )N)r � set_locationr r# r r r, )r r' r- r. r r r r> � s zBsdDbShelf.set_locationc C s. t | j�\}}t|�}|j| j�t|�j� fS )N)�nextr r r# r r r, )r r' r- r. r r r r?

The traceback module captures enough attributes from the original exception to this intermediary form to ensure that no references are held, while still being able to fully print or format it. Use `from_exception` to create TracebackException instances from exception objects, or the constructor to create TracebackException instances from individual components. - :attr:`__cause__` A TracebackException of the original *__cause__*. - :attr:`__context__` A TracebackException of the original *__context__*. - :attr:`__suppress_context__` The *__suppress_context__* value from the original exception. - :attr:`stack` A `StackSummary` representing the traceback. - :attr:`exc_type` The class of the original traceback. - :attr:`filename` For syntax errors - the filename where the error occurred. - :attr:`lineno` For syntax errors - the linenumber where the error occurred. - :attr:`text` For syntax errors - the text where the error occurred. - :attr:`offset` For syntax errors - the offset into the text where the error occurred. - :attr:`msg` For syntax errors - the compiler error message.

Because I felt like it. �_days�_seconds� _microseconds� _hashcoder c C sZ d } } } ||d 7 }||d |d 7 }||d 7 }t |t�r�tj|�\} }tj| d �\} } | t| �ksrt�t| �} |t|�ks�t�t|�}nd} |}t | t�s�t�t| �d ks�t�t |t�s�t�t| �dks�t�t |t��r(tj|�\}}|t|�k�st�t|�}|| 7 }t|�d k�s,t�n| }t |t��s<t�t|�d k�sNt�t |t��s^t�t|d�\}}||7 }| t|�7 } t | t��s�t�t| �dk�s�t�|d }t|�dk �s�t�t |t��rt|| �}t|d�\}}t|d�\}}||7 }| |7 } n@t|�}t|d�\}}t|d�\}}||7 }| |7 } t|| �}t | t��sRt�t |t��sbt�t| �d k�stt�t|�dk �s�t�t|d�\}} | |7 } t| d �\}} ||7 }t |t��s�t�t | t��r�d| k�o�d k n �s�t�t | t��rd| k�odk n �st�t|�dk�r4t d| ��t j | �}||_ | |_ | |_d |_|S )!Nr r* �< i i� g 8@g �@g g �?r! g @r g ��.Ag �@Ai@B r g ��GAi�ɚ;z$timedelta # of days is too large: %dr g �@i�Q i�Q �0 i � i�Q i�Q �H i�� i�Q i�Q r )r[ rd �_math�modfrc r �absr# �round� OverflowErrorrR �__new__r} r~ r r� )�clsrM r5 r7 r6 r4 r3 Zweeksr- rY r; ZdayfracZdaysecondsfracZdaysecondswholeZ secondsfracZusdouble�selfr r r r� d s� ,, ztimedelta.__new__c C s` | j r&d| jj| jj| j| j| j f S | jrHd| jj| jj| j| jf S d| jj| jj| jf S )Nz%s.%s(%d, %d, %d)z %s.%s(%d, %d)z %s.%s(%d))r � __class__� __module__� __qualname__r} r~ )r� r r r �__repr__� s ztimedelta.__repr__c C sd t | jd�\}}t |d�\}}d|||f }| jrLdd� }d|| j� | }| jr`|d| j }|S )Nr� z %d:%02d:%02dc S s | t | �dkrdpdfS )Nr rY rC )r� )r' r r r �plural� s z!timedelta.__str__.<locals>.pluralz %d day%s, z.%06d)r# r~ r} r )r� r/ r0 r. rY r� r r r �__str__� s ztimedelta.__str__c C s | j d | j d | j d S )z Total seconds in the duration.i�Q � r) i@B i@B )rM r5 r7 )r� r r r � total_seconds� s ztimedelta.total_secondsc C s | j S )rM )r} )r� r r r rM � s ztimedelta.daysc C s | j S )r5 )r~ )r� r r r r5 � s ztimedelta.secondsc C s | j S )r7 )r )r� r r r r7 � s ztimedelta.microsecondsc C s2 t |t�r.t| j|j | j|j | j|j �S tS )N)r[ rN r} r~ r �NotImplemented)r� �otherr r r �__add__� s ztimedelta.__add__c C s2 t |t�r.t| j|j | j|j | j|j �S tS )N)r[ rN r} r~ r r� )r� r� r r r �__sub__ s ztimedelta.__sub__c C s t |t�r| | S tS )N)r[ rN r� )r� r� r r r �__rsub__ s ztimedelta.__rsub__c C s t | j | j | j �S )N)rN r} r~ r )r� r r r �__neg__ s ztimedelta.__neg__c C s | S )Nr )r� r r r �__pos__ s ztimedelta.__pos__c C s | j dk r| S | S d S )Nr )r} )r� r r r �__abs__ s ztimedelta.__abs__c C s` t |t�r(t| j| | j| | j| �S t |t�r\| j� }|j� \}}tddt || |��S t S )Nr ) r[ rc rN r} r~ r rd �_to_microseconds�as_integer_ratior| r� )r� r� �usecrx ry r r r �__mul__# s ztimedelta.__mul__c C s | j d | j d | j S )Nr! i i@B i�Q )r} r~ r )r� r r r r� 2 s ztimedelta._to_microsecondsc C sN t |ttf�stS | j� }t |t�r0||j� S t |t�rJtdd|| �S d S )Nr )r[ rc rN r� r� )r� r� r� r r r � __floordiv__6 s ztimedelta.__floordiv__c C s~ t |tttf�stS | j� }t |t�r2||j� S t |t�rNtddt||��S t |t�rz|j� \}}tddt|| |��S d S )Nr )r[ rc rd rN r� r� r| r� )r� r� r� rx ry r r r � __truediv__? s ztimedelta.__truediv__c C s* t |t�r&| j� |j� }tdd|�S tS )Nr )r[ rN r� r� )r� r� r{ r r r �__mod__K s ztimedelta.__mod__c C s4 t |t�r0t| j� |j� �\}}|tdd|�fS tS )Nr )r[ rN r# r� r� )r� r� rz r{ r r r � __divmod__Q s ztimedelta.__divmod__c C s t |t�r| j|�dkS dS d S )Nr F)r[ rN r )r� r� r r r �__eq__Z s ztimedelta.__eq__c C s& t |t�r| j|�dkS t| |� d S )Nr )r[ rN r rw )r� r� r r r �__le__` s ztimedelta.__le__c C s& t |t�r| j|�dk S t| |� d S )Nr )r[ rN r rw )r� r� r r r �__lt__f s ztimedelta.__lt__c C s& t |t�r| j|�dkS t| |� d S )Nr )r[ rN r rw )r� r� r r r �__ge__l s ztimedelta.__ge__c C s& t |t�r| j|�dkS t| |� d S )Nr )r[ rN r rw )r� r� r r r �__gt__r s ztimedelta.__gt__c C s t |t�st�t| j� |j� �S )N)r[ rN r r � _getstate)r� r� r r r r x s ztimedelta._cmpc C s | j dkrt| j� �| _ | j S )Nr r )r� �hashr� )r� r r r �__hash__| s ztimedelta.__hash__c C s | j dkp | jdkp | jdkS )Nr )r} r~ r )r� r r r �__bool__� s ztimedelta.__bool__c C s | j | j| jfS )N)r} r~ r )r� r r r r� � s ztimedelta._getstatec C s | j | j� fS )N)r� r� )r� r r r � __reduce__� s ztimedelta.__reduce__N)r} r~ r r� )r r r r r r r )%rg r� r� �__doc__� __slots__r� r� r� r� �propertyrM r5 r7 r� �__radd__r� r� r� r� r� r� �__rmul__r� r� r� r� r� r� r� r� r� r� r r� r� r� r� r r r r rN Q sD d rN i�ɚ;rm rn i?B )rM r3 r4 r5 r7 )r7 c @ s( e Zd ZdZdCZdDdd�Zed d � �Zed d � �Zed d� �Z dd� Z dd� Z dd� Z dd� Z dd� ZeZedd� �Zedd � �Zed d � �Zd d � Zd!d"� ZdEd#d$�Zd%d&� Zd'd(� Zd)d*� Zd+d,� Zd-d.� Zd/d0� Z d1d2� Z d3d4� Z e Z d5d6� Z d7d8� Z!d9d:� Z"d;d<� Z#d=d>� Z$d?d@� Z%dAdB� Z&dS )F�datea� Concrete date type.

Instead of importing this module directly, import os and refer to this module as os.path. The "os.path" name is an alias for this module on Posix systems; on other systems (e.g. Mac, Windows), os.path provides the same operations in a manner specific to that platform, and is an alias to another module (e.g. macpath, ntpath). Some of this can actually be useful on non-Posix systems too, e.g. for manipulation of the pathname component of URLs. �.z..�/�:z:/bin:/usr/binNz /dev/null� )�*�normcase�isabs�join� splitdrive�split�splitext�basename�dirname� commonprefix�getsize�getmtime�getatime�getctime�islink�exists�lexists�isdir�isfile�ismount� expanduser� expandvars�normpath�abspath�samefile� sameopenfile�samestat�curdir�pardir�sep�pathsep�defpath�altsep�extsep�devnull�realpath�supports_unicode_filenames�relpath� commonpath� ALLOW_MISSINGc C s t | t�rdS dS d S )N� /r )� isinstance�bytes)�path� r1 �!/usr/lib64/python3.6/posixpath.py�_get_sep) s r3 c C s. t j| �} t| ttf�s*tdj| jj���| S )z6Normalize case of pathname.

It decodes the bytes according to PEP-0263 for determining source file encoding. It accepts a readline-like method which is called repeatedly to get the next line of input (or b"" for EOF). It generates 5-tuples with these members: the token type (see token.py) the token (a string) the starting (row, column) indices of the token (a 2-tuple of ints) the ending (row, column) indices of the token (a 2-tuple of ints) the original line (string) It is designed to match the working of the Python tokenizer exactly, except that it produces COMMENT tokens for comments and gives type OP for all operators. Additionally, all token lists start with an ENCODING token which tells you which encoding was used to decode the bytes stream. zKa-Ping Yee <ping@lfw.org>zpGvR, ESR, Tim Peters, Thomas Wouters, Fred Drake, Skip Montanaro, Raymond Hettinger, Trent Nelson, Michael Foord� )�open)�lookup�BOM_UTF8N)� TextIOWrapper)�chain)�*z&^[ \t\f]*#.*?coding[:=][ \t]*([-\w.]+)s ^[ \t\f]*(?:[#\r\n]|$)�COMMENT�tokenize�detect_encoding�NL� untokenize�ENCODING� TokenInfo� � � ),�(�)�[�]�:�,�;�+�-r �/�|�&�<�>�=�.�%�{�}z==z!=z<=z>=�~�^z<<z>>z**z+=z-=z*=z/=z%=z&=z|=z^=z<<=z>>=z**=z//z//=�@z@=c @ s e Zd Zdd� Zedd� �ZdS )r c C s$ d| j t| j f }d| j|d� S )Nz%d (%s)z8TokenInfo(type=%s, string=%r, start=%r, end=%r, line=%r))�type)r( �tok_name�_replace)�self�annotated_type� r- � /usr/lib64/python3.6/tokenize.py�__repr__d s zTokenInfo.__repr__c C s( | j tkr | jtkr t| j S | j S d S )N)r( �OP�string�EXACT_TOKEN_TYPES)r+ r- r- r. � exact_typei s zTokenInfo.exact_typeN)�__name__� __module__� __qualname__r/ �propertyr3 r- r- r- r. r c s ztype string start end linec G s ddj | � d S )Nr r r )�join)�choicesr- r- r. �groupp s r: c G s t | � d S )Nr )r: )r9 r- r- r. �anyq s r; c G s t | � d S )N�?)r: )r9 r- r- r. �mayber s r= z[ \f\t]*z #[^\r\n]*z\\\r?\nz\w+z0[xX](?:_?[0-9a-fA-F])+z0[bB](?:_?[01])+z0[oO](?:_?[0-7])+z (?:0(?:_?0)*|[1-9](?:_?[0-9])*)z[eE][-+]?[0-9](?:_?[0-9])*z)[0-9](?:_?[0-9])*\.(?:[0-9](?:_?[0-9])*)?z\.[0-9](?:_?[0-9])*z[0-9](?:_?[0-9])*z[0-9](?:_?[0-9])*[jJ]z[jJ]c C sn ddddddg} t dg�}xN| D ]F}x@tj|�D ]2}x,tjdd � |D �� D ]}|jdj|�� qJW q0W q W |S ) N�b�r�u�f�br�fr� c S s g | ]}||j � f�qS r- )�upper)�.0�cr- r- r. � <listcomp>� s z(_all_string_prefixes.<locals>.<listcomp>)�set� _itertools� permutations�product�addr8 )�_valid_string_prefixes�result�prefix�tr@ r- r- r. �_all_string_prefixes� s rR c C s t j| t j�S )N)�re�compile�UNICODE)�exprr- r- r. �_compile� s rW z[^'\\]*(?:\\.[^'\\]*)*'z[^"\\]*(?:\\.[^"\\]*)*"z%[^'\\]*(?:(?:\\.|'(?!''))[^'\\]*)*'''z%[^"\\]*(?:(?:\\.|"(?!""))[^"\\]*)*"""z'''z"""z '[^\n'\\]*(?:\\.[^\n'\\]*)*'z "[^\n"\\]*(?:\\.[^\n"\\]*)*"z\*\*=?z>>=?z<<=?z!=z//=?z->z[+\-*/%&@|^=<>]=?r% z[][(){}]z\r?\nz\.\.\.z[:;.,@]z'[^\n'\\]*(?:\\.[^\n'\\]*)*�'z"[^\n"\\]*(?:\\.[^\n"\\]*)*�"z \\\r?\n|\Z� c @ s e Zd ZdS )� TokenErrorN)r4 r5 r6 r- r- r- r. r[ � s r[ c @ s e Zd ZdS )�StopTokenizingN)r4 r5 r6 r- r- r- r. r\ � s r\ c @ s, e Zd Zdd� Zdd� Zdd� Zdd� Zd S ) � Untokenizerc C s g | _ d| _d| _d | _d S )Nr r )�tokens�prev_row�prev_col�encoding)r+ r- r- r. �__init__� s zUntokenizer.__init__c C s� |\}}|| j k s&|| j kr>|| jk r>tdj||| j | j���|| j }|rb| jjd| � d| _|| j }|r�| jjd| � d S )Nz+start ({},{}) precedes previous end ({},{})z\ r � )r_ r` � ValueError�formatr^ �append)r+ �start�row�col� row_offset� col_offsetr- r- r. �add_whitespace� s zUntokenizer.add_whitespacec C s4 t |�}g }d}�x|D �] }t|�dkr8| j||� P |\}}}} } |tkrV|| _q|tkr`P |tkrv|j|� qnl|tkr�|j � | \| _ | _ qnL|t t fkr�d}n:|r�|r�|d } |d t| �kr�| jj| � t| �| _ d}| j|� | jj|� | \| _ | _ |t t fkr| j d7 _ d| _ qW dj| j�S )NFr Tr r rD ���)�iter�len�compatr ra � ENDMARKER�INDENTrf �DEDENT�popr_ r` �NEWLINEr r^ rl r8 ) r+ �iterable�it�indents� startlinerQ �tok_type�tokenrg �end�line�indentr- r- r. r � sF zUntokenizer.untokenizec C s� g }| j j}|d ttfk}d}x�t|g|�D ]�}|d d� \}} |tkrR| | _q.|ttt t fkrj| d7 } |t kr�|r~d| } d}nd}|t kr�|j| � q.n>|t kr�|j� q.n*|ttfkr�d}n|r�|r�||d � d}|| � q.W d S )Nr Fr rc Tr rm )r^ rf ru r r r ra �NAME�NUMBER�ASYNC�AWAIT�STRINGrr rs rt ) r+ r{ rv rx � toks_appendry � prevstring�tok�toknum�tokvalr- r- r. rp s8 zUntokenizer.compatN)r4 r5 r6 rb rl r rp r- r- r- r. r] � s %r] c C s* t � }|j| �}|jdk r&|j|j�}|S )a Transform tokens back into Python source code.

It requires one argument, readline, in the same way as the tokenize() generator. It will call readline a maximum of twice, and return the encoding used (as a string) and a list of any lines (left as bytes) it has read in. It detects the encoding from the presence of a utf-8 bom or an encoding cookie as specified in pep-0263. If both a bom and a cookie are present, but disagree, a SyntaxError will be raised.

Each call to the function should return one line of input as bytes. Alternatively, readline can be a callable function terminating with StopIteration: readline = open(myfile, 'rb').__next__ # Example of alternate readline The generator produces 5-tuples with these members: the token type; the token string; a 2-tuple (srow, scol) of ints specifying the row and column where the token begins in the source; a 2-tuple (erow, ecol) of ints specifying the row and column where the token ends in the source; and the line on which the token was found. The line passed is the logical line; continuation lines are included. The first token sequence will always be an ENCODING token which tells you which encoding was used to decode the bytes stream. r )r �repeatr� )� itertoolsr r� r rn � _tokenize�__next__)r� r r� ra �consumed�rl_gen�emptyr- r- r. r � s c !

This module provides a class for reading and writing compressed files, classes for incremental (de)compression, and convenience functions for one-shot (de)compression.

An LZMAFile can act as a wrapper for an existing file object, or refer directly to a named file on disk.

These can equivalently be given as "rb", "wb", "xb" and "ab" respectively. format specifies the container format to use for the file. If mode is "r", this defaults to FORMAT_AUTO. Otherwise, the default is FORMAT_XZ. check specifies the integrity check to use. This argument can only be used when opening a file for writing. For FORMAT_XZ, the default is CHECK_CRC64. FORMAT_ALONE and FORMAT_RAW do not support integrity checks - for these formats, check must be omitted, or be CHECK_NONE. When opening a file for reading, the *preset* argument is not meaningful, and should be omitted. The *filters* argument should also be omitted, except when format is FORMAT_RAW (in which case it is required). When opening a file for writing, the settings used by the compressor can be specified either as a preset compression level (with the *preset* argument), or in detail as a custom filter chain (with the *filters* argument). For FORMAT_XZ and FORMAT_ALONE, the default is to use the PRESET_DEFAULT preset level. For FORMAT_RAW, the caller must always specify a filter chain; the raw compressor does not support preset compression levels. preset (if provided) should be an integer in the range 0-9, optionally OR-ed with the constant PRESET_EXTREME. filters (if provided) should be a sequence of dicts. Each dict should have an entry for "id" indicating ID of the filter, plus additional entries for options to the filter.

Interpreters constructed with this class obey the following conventions: 1. End of file on input is processed as the command 'EOF'. 2. A command is parsed out of each line by collecting the prefix composed of characters in the identchars member. 3. A command `foo' is dispatched to a method 'do_foo()'; the do_ method is passed a single argument consisting of the remainder of the line. 4. Typing an empty line repeats the last command. (Actually, it calls the method `emptyline', which may be overridden in a subclass.) 5. There is a predefined `help' method. Given an argument `topic', it calls the command `help_topic'. With no arguments, it lists all topics with defined help_ functions, broken into up to three topics; documented commands, miscellaneous help topics, and undocumented commands. 6. The command '?' is a synonym for `help'. The command '!' is a synonym for `shell', if a do_shell method exists. 7. If completion is enabled, completing commands will be done automatically, and completing of commands args is done by calling complete_foo() with arguments text, line, begidx, endidx. text is string we are matching against, all returned matches must begin with it. line is the current input line (lstripped), begidx and endidx are the beginning and end indexes of the text being matched, which could be used to provide different completion depending upon which position the argument is in. The `default' method may be overridden to intercept commands for which there is no do_ method. The `completedefault' method may be overridden to intercept completions for commands that have no complete_ method. The data member `self.ruler' sets the character used to draw separator lines in the help messages. If empty, no ruler line is drawn. It defaults to "=". If the value of `self.intro' is nonempty when the cmdloop method is called, it is printed out on interpreter startup. This value may be overridden via an optional argument to the cmdloop() method. The data members `self.doc_header', `self.misc_header', and `self.undoc_header' set the headers used for the help function's listings of documented functions, miscellaneous topics, and undocumented functions respectively. � N�Cmdz(Cmd) �_c @ s� e Zd ZdZeZeZdZdZ dZ dZ dZ dZ dZdZd Zd0d d �Zd1d d�Zdd� Zdd� Zdd� Zdd� Zdd� Zdd� Zdd � Zd d � Zd d � Zd!d"� Z d#d$� Z d%d&� Z d'd(� Z d)d*� Z d+d,� Z!d2d.d/�Z"dS )3r a A simple framework for writing line-oriented command interpreters. These are often useful for test harnesses, administrative tools, and prototypes that will later be wrapped in a more sophisticated interface. A Cmd instance or subclass instance is a line-oriented interpreter framework. There is no good reason to instantiate Cmd itself; rather, it's useful as a superclass of an interpreter class you define yourself in order to inherit Cmd's methods and encapsulate action methods. �=� Nz(Documented commands (type help <topic>):zMiscellaneous help topics:zUndocumented commands:z*** No help on %s� �tabc C s@ |dk r|| _ ntj | _ |dk r(|| _ntj| _g | _|| _dS )a� Instantiate a line-oriented interpreter framework.

The abstract syntax itself might change with each Python release; this module helps to find out programmatically what the current grammar looks like and allows modifications of it. An abstract syntax tree can be generated by passing `ast.PyCF_ONLY_AST` as a flag to the `compile()` builtin function or by using the `parse()` function from this module. The result will be a tree of objects whose classes all inherit from `ast.AST`. A modified abstract syntax tree can be compiled into a Python code object using the built-in `compile()` function. Additionally various helper functions are provided that make working with the trees simpler. The main intention of the helper functions and this module in general is to provide an easy to use interface for libraries that work tightly with the python syntax (template engines for example). :copyright: Copyright 2008 by Armin Ronacher. :license: Python License. � )�*� <unknown>�execc C s t | ||t�S )zn Parse the source into an AST node.

This function may return a value which is forwarded by the `visit` method. This class is meant to be subclassed, with the subclass adding visitor methods. Per default the visitor functions for the nodes are ``'visit_'`` + class name of the node. So a `TryFinally` node visit function would be `visit_TryFinally`. This behavior can be changed by overriding the `visit` method. If no visitor function exists for a node (return value `None`) the `generic_visit` visitor is used instead. Don't use the `NodeVisitor` if you want to apply changes to nodes during traversing. For this a special visitor exists (`NodeTransformer`) that allows modifications. c C s" d|j j }t| || j�}||�S )z Visit a node.Zvisit_)r7 r8 r2 � generic_visit)�selfr( �methodZvisitorr r r �visit� s zNodeVisitor.visitc C s\ xVt |�D ]J\}}t|t�r@x6|D ]}t|t�r"| j|� q"W q t|t�r | j|� q W dS )z9Called if no explicit visitor function exists for a node.N)r6 r r r5 r] )r[ r( r0 r rQ r r r rZ � s zNodeVisitor.generic_visitN)r8 � __module__� __qualname__�__doc__r] rZ r r r r rY � s rY c @ s e Zd ZdZdd� ZdS )�NodeTransformera\ A :class:`NodeVisitor` subclass that walks the abstract syntax tree and allows modification of nodes. The `NodeTransformer` will walk the AST and use the return value of the visitor methods to replace or remove the old node. If the return value of the visitor method is ``None``, the node will be removed from its location, otherwise it is replaced with the return value. The return value may be the original node in which case no replacement takes place. Here is an example transformer that rewrites all occurrences of name lookups (``foo``) to ``data['foo']``:: class RewriteName(NodeTransformer): def visit_Name(self, node): return copy_location(Subscript( value=Name(id='data', ctx=Load()), slice=Index(value=Str(s=node.id)), ctx=node.ctx ), node) Keep in mind that if the node you're operating on has child nodes you must either transform the child nodes yourself or call the :meth:`generic_visit` method for the node first. For nodes that were part of a collection of statements (that applies to all statement nodes), the visitor may also return a list of nodes rather than just a single node. Usually you use the transformer like this:: node = YourTransformer().visit(node) c C s� x�t |�D ]�\}}t|t�r|g }xL|D ]D}t|t�r`| j|�}|d krJq&nt|t�s`|j|� q&|j|� q&W ||d d �< q t|t�r | j|�}|d kr�t||� q t|||� q W |S )N) r6 r r r5 r] rX �append�delattrrC )r[ r( r0 Z old_valueZ new_valuesr rD r r r rZ . s& z NodeTransformer.generic_visitN)r8 r^ r_ r` rZ r r r r ra s "ra N)r r )TF)rJ )T)r` Z_astr �int�float�complexr# r+ r? rF rK rM r6 rG rT rL �objectrY ra r r r r �<module> s 0 % imghdr.cpython-36.opt-2.pyc 0000644 00000007375 15246273046 0011431 0 ustar 00 3 \� � @ s. d dl mZ dgZd$dd�Zg Zdd� Zeje� dd� Zeje� d d � Zeje� d d � Z eje � d d� Z eje � dd� Z eje � dd� Z eje � dd� Z eje � dd� Zeje� dd� Zeje� dd� Zeje� dd � Zeje� d d � Zeje� d d � Zd!d"� Zed#k�r*e� dS )%� )�PathLike�whatNc C s� d }zl|d krNt | ttf�r2t| d�}|jd�}n | j� }| jd�}| j|� x tD ]}|||�}|rT|S qTW W d |r~|j� X d S )N�rb� ) � isinstance�strr �open�read�tell�seek�tests�close)�file�h�f�locationZtf�res� r � /usr/lib64/python3.6/imghdr.pyr s c C s | dd� dkrdS d S )N� � � JFIF� ExifZjpeg)r r r )r r r r r � test_jpeg% s r c C s | j d�rdS d S )Ns �PNG Zpng)� startswith)r r r r r �test_png, s r c C s | d d� dkrdS d S )Nr � GIF87a� GIF89aZgif)r r r )r r r r r �test_gif2 s r c C s | d d� dkrdS d S )N� � MM� IIZtiff)r r! r )r r r r r � test_tiff9 s r" c C s | j d�rdS d S )Ns �Zrgb)r )r r r r r �test_rgb@ s r# c C s< t | �dkr8| d td�kr8| d dkr8| d dkr8dS d S ) N� r � P� s 14r s Zpbm)�len�ord)r r r r r �test_pbmG s (r) c C s< t | �dkr8| d td�kr8| d dkr8| d dkr8dS d S ) Nr$ r r% r& s 25r s Zpgm)r' r( )r r r r r �test_pgmO s (r* c C s< t | �dkr8| d td�kr8| d dkr8| d dkr8dS d S ) Nr$ r r% r& s 36r s Zppm)r' r( )r r r r r �test_ppmW s (r+ c C s | j d�rdS d S )Ns Y�j�Zrast)r )r r r r r � test_rast_ s r, c C s | j d�rdS d S )Ns #define Zxbm)r )r r r r r �test_xbmf s r- c C s | j d�rdS d S )Ns BMZbmp)r )r r r r r �test_bmpm s r. c C s" | j d�r | dd� dkr dS d S )Ns RIFF� � s WEBPZwebp)r )r r r r r � test_webps s r1 c C s | j d�rdS d S )Ns v/1Zexr)r )r r r r r �test_exry s r2 c C s� dd l } d}| jdd � r8| jd dkr8| jdd�= d}y8| jdd � r`t| jdd � |d� ntdg|d� W n* tk r� | jjd� | jd� Y nX d S )Nr r& z-rr �.z [Interrupted] )�sys�argv�testall�KeyboardInterrupt�stderr�write�exit)r4 � recursiver r r �test� s r< c C s� dd l }dd l}x�| D ]�}|jj|�rzt|d dd� |s>|rptd� dd l}|j|jj|d��}t||d� q�td� qt|d dd� |jj � ytt |�� W q t k r� td � Y qX qW d S ) Nr z/:� )�endzrecursing down:�*z*** directory (use -r) ***�:z*** not found ***) r4 �os�path�isdir�print�glob�joinr6 �stdout�flushr �OSError)�listr; Ztoplevelr4 rA �filenamerE �namesr r r r6 � s" r6 �__main__)N)rA r �__all__r r r �appendr r r" r# r) r* r+ r, r- r. r1 r2 r< r6 �__name__r r r r �<module> sB tempfile.cpython-36.pyc 0000644 00000055341 15246273046 0011020 0 ustar 00 3 ��i�m � @ sB d Z ddddddddd d d d d g ZddlZddlZddlZddlZ ddl Z ddl Z ddlmZ ddlZy ddlZW n ek r� ddlZY nX ejZe je jB e jB Ze e d�r�ee j O ZeZ e e d�r�e e j O Z e e d�r�e j Z ndZ dZ!e� Z"e e d��re j#Z$n e e d��r e j%Z$ndd� Z$dd� Z&dd � Z'd d � Z(G d d � d �Z)d!d"� Z*d#d$� Z+da,d%d&� Z-d'd(� Z.d)d*� Z/d+d,� Z0d-d � Z1d.d � Z2da3d/d � Z4d0d � Z5dDd2d�Z6dEd3d�Z7d4e!dfd5d�Z8G d6d7� d7�Z9G d8d9� d9�Z:dGd=d�Z;e j<d>k�se j=j>d?k�r e;Z?ne e d@�a@dIdAd�Z?G dBd� d�ZAG dCd� deB�ZCdS )Ja� Temporary files. This module provides generic, low- and high-level interfaces for creating temporary files and directories. All of the interfaces provided by this module can be used without fear of race conditions except for 'mktemp'. 'mktemp' is subject to race conditions and should not be used; it is provided for backward compatibility only. The default path names are returned as str. If you supply bytes as input, all return values will be in bytes. Ex: >>> tempfile.mkstemp() (4, '/tmp/tmptpu9nin8') >>> tempfile.mkdtemp(suffix=b'') b'/tmp/tmppbi8f0hy' This module also provides some data items to the user: TMP_MAX - maximum number of names that will be tried before giving up. tempdir - If this is set to a string before the first use of any routine from this module, it will be considered as another candidate location to store temporary files. �NamedTemporaryFile� TemporaryFile�SpooledTemporaryFile�TemporaryDirectory�mkstemp�mkdtemp�mktemp�TMP_MAX� gettempprefix�tempdir� gettempdir�gettempprefixb� gettempdirb� N)�Random� O_NOFOLLOW�O_BINARYi' Ztmp�lstat�statc C s t j| t j�}t j|� d S )N)�_os�open�O_RDONLY�close)�fn�fd� r � /usr/lib64/python3.6/tempfile.py�_statT s r c C s* y t | � W n tk r dS X dS d S )NFT)r �OSError)r r r r �_existsX s r c G s` d}xJ| D ]B}|dkrq t |t�r8|tkr2td��t}q |tkrHtd��t}q W |dkr\tS |S )zBLook at the type of all args and divine their implied return type.Nz1Can't mix bytes and non-bytes in path components.)� isinstance�bytes�str� TypeError)�argsZ return_type�argr r r �_infer_return_typea s r% c C sd t | ||�}|dkr|� }| dkr:|tkr0t} n tjt�} |dkrX|tkrRt� }nt� }| |||fS )z9Common parameter processing for most APIs in this module.N)r% r! �templater �fsencoder r )�prefix�suffix�dir� output_typer r r �_sanitize_paramsv s r, c @ s0 e Zd ZdZdZedd� �Zdd� Zdd� Zd S ) �_RandomNameSequencea, An instance of _RandomNameSequence generates an endless sequence of unpredictable strings which can safely be incorporated into file names.

The return value is a pair (fd, name) where fd is the file descriptor returned by os.open, and name is the filename. If 'suffix' is not None, the file name will end with that suffix, otherwise there will be no suffix. If 'prefix' is not None, the file name will begin with that prefix, otherwise a default prefix is used. If 'dir' is not None, the file will be created in that directory, otherwise a default directory is used. If 'text' is specified and true, the file is opened in text mode. Else (the default) the file is opened in binary mode. On some operating systems, this makes no difference. If any of 'suffix', 'prefix' and 'dir' are not None, they must be the same type. If they are bytes, the returned name will be bytes; str otherwise. The file is readable and writable only by the creating user ID. If the operating system uses permission bits to indicate whether a file is executable, the file is executable by no one. The file descriptor is not inherited by children of this process.

Instantiate with: IMAP4([host[, port]]) host - host's name (default: localhost); port - port number (default: standard IMAP4 port). All IMAP4rev1 commands are supported by methods of the same name (in lower-case). All arguments to commands are converted to strings, except for AUTHENTICATE, and the last argument to APPEND which is passed as an IMAP4 literal. If necessary (the string contains any non-printing characters or white-space and isn't enclosed with either parentheses or double quotes) each string is quoted. However, the 'password' argument to the LOGIN command is always quoted. If you want to avoid having an argument string quoted (eg: the 'flags' argument to STORE) then enclose the string in parentheses (eg: "(\Deleted)"). Each command returns a tuple: (type, [data, ...]) where 'type' is usually 'OK' or 'NO', and 'data' is either the text from the tagged response, or untagged results from command. Each 'data' is either a string, or a tuple. If a tuple, then the first part is the header of the response, and the second part contains the data (ie: 'literal' value). Errors raise the exception class <instance>.error("<reason>"). IMAP4 server errors raise <instance>.abort("<reason>"), which is a sub-class of 'error'. Mailbox status changes from READ-WRITE to READ-ONLY raise the exception class <instance>.readonly("<reason>"), which is a sub-class of 'abort'. "error" exceptions imply a program error. "abort" exceptions imply the connection should be reset, and the command re-tried. "readonly" exceptions imply the command should be re-tried. Note: to use this module, you must read the RFCs pertaining to the IMAP4 protocol, as the semantics of the arguments to each IMAP4 command are left to the invoker, not to mention the results. Also, most IMAP servers implement a sub-set of the commands available here. c @ s e Zd ZdS )z IMAP4.errorN)�__name__� __module__� __qualname__� r< r< � /usr/lib64/python3.6/imaplib.py�error� s r> c @ s e Zd ZdS )z IMAP4.abortN)r9 r: r; r< r< r< r= �abort� s r? c @ s e Zd ZdS )zIMAP4.readonlyN)r9 r: r; r< r< r< r= �readonly� s r@ � c C s� t | _d| _d | _i | _i | _d| _d| _d| _d| _ | j � | j ||� y | j � W n8 t k r� y | j� W n tk r� Y nX � Y nX d S )Nr rA Fr )�Debug�debug�state�literal�tagged_commands�untagged_responses�continuation_response� is_readonly�tagnum�_tls_established� _mode_ascii�open�_connect� Exception�shutdown�OSError)�self�host�portr< r< r= �__init__� s& zIMAP4.__init__c C s0 d| _ d| _tjttj�| _tjttj�| _d S )NF�ascii) � utf8_enabled� _encoding�re�compile�_Literal�ASCII�Literal�_Untagged_status�Untagged_status)rR r< r< r= rL � s zIMAP4._mode_asciic C s( d| _ d| _tjt�| _tjt�| _d S )NTzutf-8)rW rX rY rZ r[ r] r^ r_ )rR r< r< r= � _mode_utf8� s zIMAP4._mode_utf8c C s� t tjdd��| _tjd| j d tj�| _| j� | _ d| j krHd| _ n d| j krZd| _ n | j | j ��| j � x tD ]}|| jkr�qt|| _d S W | j d ��d S ) Ni i�� s (?P<tag>s" \d+) (?P<type>[A-Z]+) (?P<data>.*)ZPREAUTHr �OKr zserver not IMAP4 compliant)r �randomZrandint�tagprerY rZ r\ �tagre� _get_responseZwelcomerG rD r> �_get_capabilities�AllowedVersions� capabilities�PROTOCOL_VERSION)rR �versionr< r< r= rN � s zIMAP4._connectc C s& |t krt| |j� �S td| ��d S )NzUnknown IMAP4 command: '%s')�Commands�getattr�lower�AttributeError)rR �attrr< r< r= � __getattr__ s zIMAP4.__getattr__c C s | S )Nr< )rR r< r< r= � __enter__ s zIMAP4.__enter__c G s& y | j � W n tk r Y nX d S )N)�logoutrQ )rR �argsr< r< r= �__exit__ s zIMAP4.__exit__c C s | j s d n| j }tj|| jf�S )N)rS �socketZcreate_connectionrT )rR rS r< r< r= �_create_socket s zIMAP4._create_socketc C s( || _ || _| j� | _| jjd�| _dS )z�Setup connection to remote server on "host:port" (default: localhost:standard IMAP4 port).

This module encapsulates the interface provided by the internal special attributes (co_*, im_*, tb_*, etc.) in a friendlier fashion. It also provides some help for examining source code and class layout. Here are some of the useful functions provided by this module: ismodule(), isclass(), ismethod(), isfunction(), isgeneratorfunction(), isgenerator(), istraceback(), isframe(), iscode(), isbuiltin(), isroutine() - check object types getmembers() - get members of an object that satisfy a given condition getfile(), getsourcefile(), getsource() - find an object's source code getdoc(), getcomments() - get documentation on an object getmodule() - determine the module that an object came from getclasstree() - arrange classes so as to represent their hierarchy getargvalues(), getcallargs() - get info about function arguments getfullargspec() - same, with support for Python 3 features formatargspec(), formatargvalues() - format an argument spec getouterframes(), getinnerframes() - get info about frames currentframe() - get the current stack frame stack(), trace() - get info about frames on the stack or in a traceback signature() - get a Signature object for the callable �Ka-Ping Yee <ping@lfw.org>�'Yury Selivanov <yselivanov@sprymix.com>� N)� attrgetter)� namedtuple� OrderedDictZCO_� � c C s t | tj�S )z�Return true if the object is a module.

It stores a Parameter object for each parameter accepted by the function, as well as information specific to the function itself. A Signature object has the following public attributes and methods: * parameters : OrderedDict An ordered mapping of parameters' names to the corresponding Parameter objects (keyword-only arguments are in the same order as listed in `code.co_varnames`). * return_annotation : object The annotation for the return type of the function if specified. If the function has no annotation for its return type, this attribute is set to `Signature.empty`. * bind(*args, **kwargs) -> BoundArguments Creates a mapping from positional and keyword arguments to parameters. * bind_partial(*args, **kwargs) -> BoundArguments Creates a partial mapping from positional and keyword arguments to parameters (simulating 'functools.partial' behavior.) �_return_annotation� _parametersNT)r$ r� c C s� |dkrt � }n�|r�t � }t}d}x�t|�D ]�\}}|j} |j} | |k rjd} | jt|�t| ��} t| ��n| |krzd}| }| ttfkr�|j t kr�|r�d} t| ��nd}| |kr�dj| �} t| ��||| < q,W nt dd� |D ��}t j |�| _ || _dS ) z�Constructs Signature from the given list of Parameter objects and 'return_annotation'.

This is a descriptor, used to define attributes that act differently when accessed through an instance and through a class. Instance access remains normal, but access to an attribute through a class will be routed to the class's __getattr__ method; this is done by raising AttributeError. This allows one to have properties active on an instance, and have virtual attributes on the class with the same name (see Enum for an example).

The public interface consists of the wrap() and fill() methods; the other methods are just there for subclasses to override in order to tweak the default behaviour. If you want to completely replace the main wrapping algorithm, you'll probably have to override _wrap_chunks(). Several instance attributes control various aspects of wrapping: width (default: 70) the maximum width of wrapped lines (unless break_long_words is false) initial_indent (default: "") string that will be prepended to the first line of wrapped output. Counts towards the line's width. subsequent_indent (default: "") string that will be prepended to all lines save the first of wrapped output; also counts towards each line's width. expand_tabs (default: true) Expand tabs in input text to spaces before further processing. Each tab will become 0 .. 'tabsize' spaces, depending on its position in its line. If false, each tab is treated as a single character. tabsize (default: 8) Expand tabs in input text to 0 .. 'tabsize' spaces, unless 'expand_tabs' is false. replace_whitespace (default: true) Replace all whitespace characters in the input text by spaces after tab expansion. Note that if expand_tabs is false and replace_whitespace is true, every tab will be converted to a single space! fix_sentence_endings (default: false) Ensure that sentence-ending punctuation is always followed by two spaces. Off by default because the algorithm is (unavoidably) imperfect. break_long_words (default: true) Break words longer than 'width'. If false, those words will not be broken, and some lines might be longer than 'width'. break_on_hyphens (default: true) Allow breaking hyphenated words. If true, wrapping will occur preferably on whitespaces and right after hyphens part of compound words. drop_whitespace (default: true) Drop leading and trailing whitespace from lines. max_lines (default: None) Truncate wrapped lines. placeholder (default: ' [...]') Append to the last line of truncated text. � z [\w!"\'&.,?]z[^\d\W]z[%s]z[^� Na� ( # any whitespace %(ws)s+ | # em-dash between words (?<=%(wp)s) -{2,} (?=\w) | # word, possibly hyphenated %(nws)s+?

As an example, the text Look, goof-ball -- use the -b option! breaks into the following chunks: 'Look,', ' ', 'goof-', 'ball', ' ', '--', ' ', 'use', ' ', 'the', ' ', '-b', ' ', 'option!' if break_on_hyphens is True, or in: 'Look,', ' ', 'goof-ball', ' ', '--', ' ', 'use', ' ', 'the', ' ', '-b', ' ', option!' otherwise.

(If 'break_long_words' is false, some lines may be longer than this.) Chunks correspond roughly to words and the whitespace between them: each chunk is indivisible (modulo 'break_long_words'), but a line break can come between any two chunks. Chunks should not have internal whitespace; ie. a chunk is either all whitespace or a "word". Whitespace chunks will be removed from the beginning and end of lines, but apart from that whitespace is preserved. r z invalid width %r (must be > 0)Nr z#placeholder too large for max widthr r1 r1 r1 r1 r1 r1 r1 r1 r1 r1 r1 r1 )r � ValueErrorr r r r. r �lstrip�reverser �stripr2 r3 r6 �sum�map�join�rstrip) r r) �linesr r4 r5 r �lZ prev_liner r r � _wrap_chunks� sp zTextWrapper._wrap_chunksc C s | j |�}| j|�S )N)r" r* )r r! r r r � _split_chunksP s zTextWrapper._split_chunksc C s$ | j |�}| jr| j|� | j|�S )a^ wrap(text : string) -> [string] Reformat the single paragraph in 'text' so it fits in lines of no more than 'self.width' columns, and return a list of wrapped lines.

Note that tabs and spaces are both treated as whitespace, but they are not equal: the lines " hello" and "\thello" are considered to have no common leading whitespace. (This behaviour is new in Python 2.5; older versions of this module incorrectly expanded tabs before searching for common leading whitespace.)

Pythonic support for SSL. Object types: SSLSocket -- subtype of socket.socket which does SSL over the socket Exceptions: SSLError -- exception raised for I/O errors Functions: cert_time_to_seconds -- convert time string used for certificate notBefore and notAfter functions to integer seconds past the Epoch (the time values returned from time.time()) fetch_server_certificate (HOST, PORT) -- fetch the certificate provided by the server running on HOST at port PORT. No validation of the certificate is performed.

This object captures the state of an SSL connection but does not provide any network IO itself. IO needs to be performed through separate "BIO" objects which are OpenSSL's IO abstraction layer. This class does not have a public constructor. Instances are returned by ``SSLContext.wrap_bio``. This class is typically used by framework authors that want to implement asynchronous IO for SSL through memory buffers. When compared to ``SSLSocket``, this object lacks the following features: * Any form of network IO, including methods such as ``recv`` and ``send``. * The ``do_handshake_on_connect`` and ``suppress_ragged_eofs`` machinery.

Interface summary: import copy x = copy.copy(y) # make a shallow copy of y x = copy.deepcopy(y) # make a deep copy of y For module specific errors, copy.Error is raised. The difference between shallow and deep copying is only relevant for compound objects (objects that contain other objects, like lists or class instances). - A shallow copy constructs a new compound object and then (to the extent possible) inserts *the same objects* into it that the original contains. - A deep copy constructs a new compound object and then, recursively, inserts *copies* into it of the objects found in the original. Two problems often exist with deep copy operations that don't exist with shallow copy operations: a) recursive objects (compound objects that, directly or indirectly, contain a reference to themselves) may cause a recursive loop b) because deep copy copies *everything* it may copy too much, e.g. administrative data structures that should be shared even between copies Python's deep copy operation avoids these problems by: a) keeping a table of objects already copied during the current copying pass b) letting user-defined classes override the copying operation or the set of components copied This version does not copy types like module, class, function, method, nor stack trace, stack frame, nor file, socket, window, nor array, nor any similar types. Classes can use the same interfaces to control copying that they use to control pickling: they can define methods called __getinitargs__(), __getstate__() and __setstate__(). See the documentation for module "pickle" for information on these methods. � N)�dispatch_tablec @ s e Zd ZdS )�ErrorN)�__name__� __module__� __qualname__� r r � /usr/lib64/python3.6/copy.pyr 7 s r )� PyStringMap�copy�deepcopyc C s� t | �}tj|�}|r || �S yt|t �}W n tk rD d}Y nX |rRt| �S t|dd�}|rj|| �S tj|�}|r�|| �}n>t| dd�}|r�|d�}n$t| dd�}|r�|� }n td| ��t |t �r�| S t | df|�� S )zlShallow copy operation on arbitrary Python objects.

Args: address: A string or integer representing the IP [& network]. '192.0.2.0/24' '192.0.2.0/255.255.255.0' '192.0.0.2/0.0.0.255' are all functionally the same in IPv4. Similarly, '192.0.2.1' '192.0.2.1/255.255.255.255' '192.0.2.1/32' are also functionally equivalent. That is to say, failing to provide a subnetmask will create an object with a mask of /32. If the mask (portion after the / in the argument) is given in dotted quad form, it is treated as a netmask if it starts with a non-zero field (e.g. /255.0.0.0 == /8) and as a hostmask if it starts with a zero field (e.g. 0.255.255.255 == /8), with the single exception of an all-zero mask which is treated as a netmask == /0. If no mask is given, a default of /32 is used. Additionally, an integer can be passed, so IPv4Network('192.0.2.1') == IPv4Network(3221225985) or, more generally IPv4Interface(int(IPv4Interface('192.0.2.1'))) == IPv4Interface('192.0.2.1') Raises: AddressValueError: If ipaddress isn't a valid IPv4 address.

'2001:db8::/128' '2001:db8:0000:0000:0000:0000:0000:0000/128' '2001:db8::' are all functionally the same in IPv6. That is to say, failing to provide a subnetmask will create an object with a mask of /128. Additionally, an integer can be passed, so IPv6Network('2001:db8::') == IPv6Network(42540766411282592856903984951653826560) or, more generally IPv6Network(int(IPv6Network('2001:db8::'))) == IPv6Network('2001:db8::') strict: A boolean. If true, ensure that we have been passed A true network address, eg, 2001:db8::1000/124 and not an IP address on a network, eg, 2001:db8::1/124. Raises: AddressValueError: If address isn't a valid IPv6 address. NetmaskValueError: If the netmask isn't valid for an IPv6 address. ValueError: If strict was True and a network address was not supplied. r r& r z%s has host bits setN)rO r� r5 rk r� r9 r� r# r% rm r rK r� r� rI r r� r� )rW r r r$ r� r� r� r r r r� � s( zIPv6Network.__init__c c s@ t | j�}t | j�}x&t|d |d �D ]}| j|�V q(W dS )z�Generate Iterator over usable hosts in a network.

If no *abcs* are given, the algorithm works exactly like the built-in C3 linearization used for method resolution. If given, *abcs* is a list of abstract base classes that should be inserted into the resulting MRO. Unrelated ABCs are ignored and don't end up in the result. The algorithm inserts ABCs where their functionality is introduced, i.e. issubclass(cls, abc) returns True for the class itself but returns False for all its direct base classes. Implicit ABCs for a given class (either registered or inferred from the presence of a special method like __len__) are inserted directly after the last ABC explicitly listed in the MRO of said class. If two implicit ABCs end up next to each other in the resulting MRO, their ordering depends on the order of types in *abcs*. �__abstractmethods__r Nc 3 s | ]}t |� �V qd S )N)� issubclass)r@ �b)�baser r rc � s z_c3_mro.<locals>.<genexpr>c s g | ]}t |� d ��qS ))�abcs)�_c3_mro)r@ r� )r� r r rC � s z_c3_mro.<locals>.<listcomp>c s g | ]}t |� d ��qS ))r� )r� )r@ r� )r� r r rC � s c s g | ]}t |� d ��qS ))r� )r� )r@ r� )r� r r rC � s ) � enumerate�reversed� __bases__r[ rX �listr� �anyr� �remover� ) rB r� �i�boundary�explicit_bases�abstract_bases� other_bases�explicit_c3_mros�abstract_c3_mros� other_c3_mrosr )r� r� r r� ~ s( r� c s� t �j�� � �fdd���fdd��D ���fdd���fdd��D ��t ���g }x��D ]�}g }x<|j� D ]0}|� krlt�|�rl|j�fdd�|jD �� qlW |s�|j|� qZ|jtd d � x,|D ]$}x |D ]}||kr�|j|� q�W q�W qZW t�|d �S ) z�Calculates the method resolution order for a given class *cls*.

Arguments can be strings or integers (where appropriate) (e.g.: retr(1) and retr('1') both work equally well. Minimal Command Set: USER name user(name) PASS string pass_(string) STAT stat() LIST [msg] list(msg = None) RETR msg retr(msg) DELE msg dele(msg) NOOP noop() RSET rset() QUIT quit() Optional Commands (some servers support these): RPOP name rpop(name) APOP name digest apop(name, digest) TOP msg n top(msg, n) UIDL [msg] uidl(msg = None) CAPA capa() STLS stls() UTF8 utf8() Raises one exception: 'error_proto'. Instantiate with: POP3(hostname, port=110) NB: the POP protocol locks the mailbox from user authorization until QUIT, so be sure to get in, suck the messages, and quit, each time you access the mailbox. POP is a line-based protocol, which means large mail messages consume lots of python cycles reading them line-by-line. If it's available on your mail server, use IMAP4 instead, it doesn't suffer from the two problems above. zUTF-8c C s@ || _ || _d| _| j|�| _| jjd�| _d| _| j� | _ d S )NF�rbr ) �host�port�_tls_established�_create_socket�sock�makefile�file� _debugging�_getresp�welcome)�selfr r �timeoutr r r �__init__a s z POP3.__init__c C s t j| j| jf|�S )N)�socketZcreate_connectionr r )r r r r r r k s zPOP3._create_socketc C s, | j dkrtdt|�� | jj|t � d S )N� z*put*)r �print�reprr Zsendall�CRLF)r �liner r r �_putlinen s z POP3._putlinec C sB | j rtdt|�� t|| j�}tjd|�r4td��| j|� d S )Nz*cmd*s [ - ]z*Control characters not allowed in commands) r r r �bytes�encoding�re�search� ValueErrorr )r r r r r �_putcmdu s z POP3._putcmdc C s� | j jtd �}t|�tkr$td��| jdkr<tdt|�� |sHtd��t|�}|dd � tkrp|d d� |fS |d d� t kr�|dd� |fS |d d � |fS ) Nr z line too longz*get*z-ERR EOF� ���r( ���r) ) r �readline�_MAXLINE�lenr r r r r �CR)r r �octetsr r r �_getline� s z POP3._getlinec C s: | j � \}}| jdkr$tdt|�� |jd�s6t|��|S )Nr z*resp*� +)r/ r r r � startswithr )r �resp�or r r r � s z POP3._getrespc C sp | j � }g }d}| j� \}}xH|dkrd|jd�rD|d }|dd � }|| }|j|� | j� \}}q W |||fS )Nr � .s ..r )r r/ r1 �append)r r2 �listr. r r3 r r r � _getlongresp� s zPOP3._getlongrespc C s | j |� | j� S )N)r& r )r r r r r � _shortcmd� s zPOP3._shortcmdc C s | j |� | j� S )N)r& r7 )r r r r r �_longcmd� s z POP3._longcmdc C s | j S )N)r )r r r r � getwelcome� s zPOP3.getwelcomec C s || _ d S )N)r )r �levelr r r �set_debuglevel� s zPOP3.set_debuglevelc C s | j d| �S )zVSend user name, return response (should indicate password required). zUSER %s)r8 )r �userr r r r= � s z POP3.userc C s | j d| �S )z�Send password, return response (response includes message count, mailbox size).

To create a connection, call the class using these arguments: host, user, passwd, acct, timeout The first four arguments are all strings, and have default value ''. timeout must be numeric and defaults to None if not passed, meaning that no timeout will be set on any ftp socket(s) If a timeout is passed, then this is now the default timeout for all ftp socket operations for this instance. Then use self.connect() with optional host and port argument. To download a file, use ftp.retrlines('RETR ' + filename), or ftp.retrbinary() with slightly different arguments. To upload a file, use ftp.storlines() or ftp.storbinary(), which have an open file as argument (see their definitions below for details). The download/upload functions first issue appropriate TYPE and PORT or PASV commands. r � Nr zlatin-1Fc C s0 || _ || _|r,| j|� |r,| j|||� d S )N)�source_address�timeout�connect�login)�self�host�user�passwd�acctr r r r r �__init__r s z FTP.__init__c C s | S )Nr )r r r r � __enter__{ s z FTP.__enter__c G sN | j d k rJz*y | j� W n ttfk r0 Y nX W d | j d k rH| j� X d S )N)�sock�quit�OSError�EOFError�close)r �argsr r r �__exit__ s z FTP.__exit__i� c C s� |dkr|| _ |dkr || _|dkr*|| _|dk r8|| _tj| j | jf| j| jd�| _| jj| _| jj d| j d�| _ | j � | _ | j S ) aw Connect to host.

Heaps are arrays for which a[k] <= a[2*k+1] and a[k] <= a[2*k+2] for all k, counting elements from 0. For the sake of comparison, non-existing elements are considered to be infinite. The interesting property of a heap is that a[0] is always its smallest element. Usage: heap = [] # creates an empty heap heappush(heap, item) # pushes a new item on the heap item = heappop(heap) # pops the smallest item from the heap item = heap[0] # smallest item on the heap without popping it heapify(x) # transforms list into a heap, in-place, in linear time item = heapreplace(heap, item) # pops and returns smallest item, and adds # new item; the heap size is unchanged Our API differs from textbook heap algorithms as follows: - We use 0-based indexing. This makes the relationship between the index for a node and the indexes for its children slightly less obvious, but is more suitable since Python uses 0-based indexing. - Our heappop() method returns the smallest item, not the largest. These two make it possible to view the heap as a regular Python list without surprises: heap[0] is the smallest item, and heap.sort() maintains the heap invariant! uo Heap queues [explanation by François Pinard] Heaps are arrays for which a[k] <= a[2*k+1] and a[k] <= a[2*k+2] for all k, counting elements from 0. For the sake of comparison, non-existing elements are considered to be infinite. The interesting property of a heap is that a[0] is always its smallest element. The strange invariant above is meant to be an efficient memory representation for a tournament. The numbers below are `k', not a[k]: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 In the tree above, each cell `k' is topping `2*k+1' and `2*k+2'. In a usual binary tournament we see in sports, each cell is the winner over the two cells it tops, and we can trace the winner down the tree to see all opponents s/he had. However, in many computer applications of such tournaments, we do not need to trace the history of a winner. To be more memory efficient, when a winner is promoted, we try to replace it by something else at a lower level, and the rule becomes that a cell and the two cells it tops contain three different items, but the top cell "wins" over the two topped cells. If this heap invariant is protected at all time, index 0 is clearly the overall winner. The simplest algorithmic way to remove it and find the "next" winner is to move some loser (let's say cell 30 in the diagram above) into the 0 position, and then percolate this new 0 down the tree, exchanging values, until the invariant is re-established. This is clearly logarithmic on the total number of items in the tree. By iterating over all items, you get an O(n ln n) sort. A nice feature of this sort is that you can efficiently insert new items while the sort is going on, provided that the inserted items are not "better" than the last 0'th element you extracted. This is especially useful in simulation contexts, where the tree holds all incoming events, and the "win" condition means the smallest scheduled time. When an event schedule other events for execution, they are scheduled into the future, so they can easily go into the heap. So, a heap is a good structure for implementing schedulers (this is what I used for my MIDI sequencer :-). Various structures for implementing schedulers have been extensively studied, and heaps are good for this, as they are reasonably speedy, the speed is almost constant, and the worst case is not much different than the average case. However, there are other representations which are more efficient overall, yet the worst cases might be terrible. Heaps are also very useful in big disk sorts. You most probably all know that a big sort implies producing "runs" (which are pre-sorted sequences, which size is usually related to the amount of CPU memory), followed by a merging passes for these runs, which merging is often very cleverly organised[1]. It is very important that the initial sort produces the longest runs possible. Tournaments are a good way to that. If, using all the memory available to hold a tournament, you replace and percolate items that happen to fit the current run, you'll produce runs which are twice the size of the memory for random input, and much better for input fuzzily ordered. Moreover, if you output the 0'th item on disk and get an input which may not fit in the current tournament (because the value "wins" over the last output value), it cannot fit in the heap, so the size of the heap decreases. The freed memory could be cleverly reused immediately for progressively building a second heap, which grows at exactly the same rate the first heap is melting. When the first heap completely vanishes, you switch heaps and start a new run. Clever and quite effective! In a word, heaps are useful memory structures to know. I use them in a few applications, and I think it is good to keep a `heap' module around. :-) -------------------- [1] The disk balancing algorithms which are current, nowadays, are more annoying than clever, and this is a consequence of the seeking capabilities of the disks. On devices which cannot seek, like big tape drives, the story was quite different, and one had to be very clever to ensure (far in advance) that each tape movement will be the most effective possible (that is, will best participate at "progressing" the merge). Some tapes were even able to read backwards, and this was also used to avoid the rewinding time. Believe me, real good tape sorts were quite spectacular to watch! From all times, sorting has always been a Great Art! :-) �heappush�heappop�heapify� heapreplace�merge�nlargest� nsmallest� heappushpopc C s" | j |� t| dt| �d � dS )z4Push item onto heap, maintaining the heap invariant.� � N)�append� _siftdown�len)�heap�item� r � /usr/lib64/python3.6/heapq.pyr � s c C s. | j � }| r*| d }|| d< t| d� |S |S )zCPop the smallest item off the heap, maintaining the heap invariant.r )�pop�_siftup)r �lastelt� returnitemr r r r � s c C s | d }|| d< t | d� |S )a� Pop and return the current smallest value, and add the new item.

Arguments are as for compile_command(). One several things can happen: 1) The input is incorrect; compile_command() raised an exception (SyntaxError or OverflowError). A syntax traceback will be printed by calling the showsyntaxerror() method. 2) The input is incomplete, and more input is required; compile_command() returned None. Nothing happens. 3) The input is complete; compile_command() returned a code object. The code is executed by calling self.runcode() (which also handles run-time exceptions, except for SystemExit). The return value is True in case 2, False in the other cases (unless an exception is raised). The return value can be used to decide whether to use sys.ps1 or sys.ps2 to prompt the next line.

The optional banner argument specifies the banner to print before the first interaction; by default it prints a banner similar to the one printed by the real Python interpreter, followed by the current class name in parentheses (so as not to confuse this with the real interpreter -- since it's so close!). The optional exitmsg argument specifies the exit message printed when exiting. Pass the empty string to suppress printing an exit message.

The line should not have a trailing newline; it may have internal newlines. The line is appended to a buffer and the interpreter's runsource() method is called with the concatenated contents of the buffer as source. If this indicates that the command was executed or invalid, the buffer is reset; otherwise, the command is incomplete, and the buffer is left as it was after the line was appended.

This module provides regular expression matching operations similar to those found in Perl. It supports both 8-bit and Unicode strings; both the pattern and the strings being processed can contain null bytes and characters outside the US ASCII range. Regular expressions can contain both special and ordinary characters. Most ordinary characters, like "A", "a", or "0", are the simplest regular expressions; they simply match themselves. You can concatenate ordinary characters, so last matches the string 'last'. The special characters are: "." Matches any character except a newline. "^" Matches the start of the string. "$" Matches the end of the string or just before the newline at the end of the string. "*" Matches 0 or more (greedy) repetitions of the preceding RE. Greedy means that it will match as many repetitions as possible. "+" Matches 1 or more (greedy) repetitions of the preceding RE. "?" Matches 0 or 1 (greedy) of the preceding RE. *?,+?,?? Non-greedy versions of the previous three special characters. {m,n} Matches from m to n repetitions of the preceding RE. {m,n}? Non-greedy version of the above. "\\" Either escapes special characters or signals a special sequence. [] Indicates a set of characters. A "^" as the first character indicates a complementing set. "|" A|B, creates an RE that will match either A or B. (...) Matches the RE inside the parentheses. The contents can be retrieved or matched later in the string. (?aiLmsux) Set the A, I, L, M, S, U, or X flag for the RE (see below). (?:...) Non-grouping version of regular parentheses. (?P<name>...) The substring matched by the group is accessible by name. (?P=name) Matches the text matched earlier by the group named name. (?#...) A comment; ignored. (?=...) Matches if ... matches next, but doesn't consume the string. (?!...) Matches if ... doesn't match next. (?<=...) Matches if preceded by ... (must be fixed length). (?<!...) Matches if not preceded by ... (must be fixed length). (?(id/name)yes|no) Matches yes pattern if the group with id/name matched, the (optional) no pattern otherwise. The special sequences consist of "\\" and a character from the list below. If the ordinary character is not on the list, then the resulting RE will match the second character. \number Matches the contents of the group of the same number. \A Matches only at the start of the string. \Z Matches only at the end of the string. \b Matches the empty string, but only at the start or end of a word. \B Matches the empty string, but not at the start or end of a word. \d Matches any decimal digit; equivalent to the set [0-9] in bytes patterns or string patterns with the ASCII flag. In string patterns without the ASCII flag, it will match the whole range of Unicode digits. \D Matches any non-digit character; equivalent to [^\d]. \s Matches any whitespace character; equivalent to [ \t\n\r\f\v] in bytes patterns or string patterns with the ASCII flag. In string patterns without the ASCII flag, it will match the whole range of Unicode whitespace characters. \S Matches any non-whitespace character; equivalent to [^\s]. \w Matches any alphanumeric character; equivalent to [a-zA-Z0-9_] in bytes patterns or string patterns with the ASCII flag. In string patterns without the ASCII flag, it will match the range of Unicode alphanumeric characters (letters plus digits plus underscore). With LOCALE, it will match the set [0-9_] plus characters defined as letters for the current locale. \W Matches the complement of \w. \\ Matches a literal backslash. This module exports the following functions: match Match a regular expression pattern to the beginning of a string. fullmatch Match a regular expression pattern to all of a string. search Search a string for the presence of a pattern. sub Substitute occurrences of a pattern found in a string. subn Same as sub, but also return the number of substitutions made. split Split a string by the occurrences of a pattern. findall Find all occurrences of a pattern in a string. finditer Return an iterator yielding a match object for each match. compile Compile a pattern into a RegexObject. purge Clear the regular expression cache. escape Backslash all non-alphanumerics in a string. Some of the functions in this module takes flags as optional parameters: A ASCII For string patterns, make \w, \W, \b, \B, \d, \D match the corresponding ASCII character categories (rather than the whole Unicode categories, which is the default). For bytes patterns, this flag is the only available behaviour and needn't be specified. I IGNORECASE Perform case-insensitive matching. L LOCALE Make \w, \W, \b, \B, dependent on the current locale. M MULTILINE "^" matches the beginning of lines (after a newline) as well as the string. "$" matches the end of lines (before a newline) as well as the end of the string. S DOTALL "." matches any character at all, including the newline. X VERBOSE Ignore whitespace and comments for nicer looking RE's. U UNICODE For compatibility only. Ignored for string patterns (it is the default), and forbidden for bytes patterns. This module also defines an exception 'error'. � N�match� fullmatch�search�sub�subn�split�findall�finditer�compile�purge�template�escape�error�A�I�L�M�S�X�U�ASCII� IGNORECASE�LOCALE� MULTILINE�DOTALL�VERBOSE�UNICODEz2.2.1c @ sb e Zd ZejZejZejZ ej Z ej Z ejZejZeZeZe Ze Ze ZeZeZejZeZej Z dS )� RegexFlagN) �__name__� __module__� __qualname__� sre_compile�SRE_FLAG_ASCIIr �SRE_FLAG_IGNORECASEr �SRE_FLAG_LOCALEr �SRE_FLAG_UNICODEr �SRE_FLAG_MULTILINEr �SRE_FLAG_DOTALLr �SRE_FLAG_VERBOSEr r r r r r r r �SRE_FLAG_TEMPLATE�TEMPLATE�T�SRE_FLAG_DEBUG�DEBUG� r. r. �/usr/lib64/python3.6/re.pyr � s" r c C s t | |�j|�S )zqTry to apply the pattern at the start of the string, returning a match object, or None if no match was found.)�_compiler )�pattern�string�flagsr. r. r/ r � s c C s t | |�j|�S )zkTry to apply the pattern to all of the string, returning a match object, or None if no match was found.)r0 r )r1 r2 r3 r. r. r/ r � s c C s t | |�j|�S )ztScan through string looking for a match to the pattern, returning a match object, or None if no match was found.)r0 r )r1 r2 r3 r. r. r/ r � s c C s t | |�j|||�S )aZ Return the string obtained by replacing the leftmost non-overlapping occurrences of the pattern in string by the replacement repl. repl can be either a string or a callable; if a string, backslash escapes in it are processed.

The basic algorithm predates, and is a little fancier than, an algorithm published in the late 1980's by Ratcliff and Obershelp under the hyperbolic name "gestalt pattern matching". The basic idea is to find the longest contiguous matching subsequence that contains no "junk" elements (R-O doesn't address junk). The same idea is then applied recursively to the pieces of the sequences to the left and to the right of the matching subsequence. This does not yield minimal edit sequences, but does tend to yield matches that "look right" to people. SequenceMatcher tries to compute a "human-friendly diff" between two sequences. Unlike e.g. UNIX(tm) diff, the fundamental notion is the longest *contiguous* & junk-free matching subsequence. That's what catches peoples' eyes. The Windows(tm) windiff has another interesting notion, pairing up elements that appear uniquely in each sequence. That, and the method here, appear to yield more intuitive difference reports than does diff. This method appears to be the least vulnerable to synching up on blocks of "junk lines", though (like blank lines in ordinary text files, or maybe "<P>" lines in HTML files). That may be because this is the only method of the 3 that has a *concept* of "junk" <wink>. Example, comparing two strings, and considering blanks to be "junk": >>> s = SequenceMatcher(lambda x: x == " ", ... "private Thread currentThread;", ... "private volatile Thread currentThread;") >>> .ratio() returns a float in [0, 1], measuring the "similarity" of the sequences. As a rule of thumb, a .ratio() value over 0.6 means the sequences are close matches: >>> print(round(s.ratio(), 3)) 0.866 >>> If you're only interested in where the sequences match, .get_matching_blocks() is handy: >>> for block in s.get_matching_blocks(): ... print("a[%d] and b[%d] match for %d elements" % block) a[0] and b[0] match for 8 elements a[8] and b[17] match for 21 elements a[29] and b[38] match for 0 elements Note that the last tuple returned by .get_matching_blocks() is always a dummy, (len(a), len(b), 0), and this is the only case in which the last tuple element (number of elements matched) is 0. If you want to know how to change the first sequence into the second, use .get_opcodes(): >>> for opcode in s.get_opcodes(): ... print("%6s a[%d:%d] b[%d:%d]" % opcode) equal a[0:8] b[0:8] insert a[8:8] b[8:17] equal a[8:29] b[17:38] See the Differ class for a fancy human-friendly file differencer, which uses SequenceMatcher both to compare sequences of lines, and to compare sequences of characters within similar (near-matching) lines. See also function get_close_matches() in this module, which shows how simple code building on SequenceMatcher can be used to do useful work. Timing: Basic R-O is cubic time worst case and quadratic time expected case. SequenceMatcher is quadratic time for the worst case and has expected-case behavior dependent in a complicated way on how many elements the sequences have in common; best case time is linear. Methods: __init__(isjunk=None, a='', b='') Construct a SequenceMatcher. set_seqs(a, b) Set the two sequences to be compared. set_seq1(a) Set the first sequence to be compared. set_seq2(b) Set the second sequence to be compared. find_longest_match(alo, ahi, blo, bhi) Find longest matching block in a[alo:ahi] and b[blo:bhi]. get_matching_blocks() Return list of triples describing matching subsequences. get_opcodes() Return list of 5-tuples describing how to turn a into b. ratio() Return a measure of the sequences' similarity (float in [0,1]). quick_ratio() Return an upper bound on .ratio() relatively quickly. real_quick_ratio() Return an upper bound on ratio() very quickly. N� Tc C s( || _ d | _| _|| _| j||� dS )a! Construct a SequenceMatcher. Optional arg isjunk is None (the default), or a one-argument function that takes a sequence element and returns true iff the element is junk. None is equivalent to passing "lambda x: 0", i.e. no elements are considered to be junk. For example, pass lambda x: x in " \t" if you're comparing lines as sequences of characters, and don't want to synch up on blanks or hard tabs. Optional arg a is the first of two sequences to be compared. By default, an empty string. The elements of a must be hashable. See also .set_seqs() and .set_seq1(). Optional arg b is the second of two sequences to be compared. By default, an empty string. The elements of b must be hashable. See also .set_seqs() and .set_seq2(). Optional arg autojunk should be set to False to disable the "automatic junk heuristic" that treats popular elements as junk (see module documentation for more information).

If isjunk is not defined: Return (i,j,k) such that a[i:i+k] is equal to b[j:j+k], where alo <= i <= i+k <= ahi blo <= j <= j+k <= bhi and for all (i',j',k') meeting those conditions, k >= k' i <= i' and if i == i', j <= j' In other words, of all maximal matching blocks, return one that starts earliest in a, and of all those maximal matching blocks that start earliest in a, return the one that starts earliest in b. >>> s = SequenceMatcher(None, " abcd", "abcd abcd") >>> s.find_longest_match(0, 5, 0, 9) Match(a=0, b=4, size=5) If isjunk is defined, first the longest matching block is determined as above, but with the additional restriction that no junk element appears in the block. Then that block is extended as far as possible by matching (only) junk elements on both sides. So the resulting block never matches on junk except as identical junk happens to be adjacent to an "interesting" match. Here's the same example as before, but considering blanks to be junk. That prevents " abcd" from matching the " abcd" at the tail end of the second sequence directly. Instead only the "abcd" can match, and matches the leftmost "abcd" in the second sequence: >>> s = SequenceMatcher(lambda x: x==" ", " abcd", "abcd abcd") >>> s.find_longest_match(0, 5, 0, 9) Match(a=1, b=0, size=4) If no blocks match, return (alo, blo, 0). >>> s = SequenceMatcher(None, "ab", "c") >>> s.find_longest_match(0, 2, 0, 1) Match(a=0, b=0, size=0) r r% )r r r& r+ � __contains__�range�getr )r �alo�ahi�blo�bhir r r& ZisbjunkZbestiZbestjZbestsizeZj2lenZnothingr0 Zj2lengetZnewj2len�j�kr r r �find_longest_matchP sB 8 $ " z"SequenceMatcher.find_longest_matchc C s� | j dk r| j S t| j�t| j� }}d|d|fg}g }x�|r�|j� \}}}}| j||||� \} } } } | r:|j| � || k r�|| k r�|j|| || f� | | |k r:| | |k r:|j| | || | |f� q:W |j� d } }}g }x^|D ]V\}}}| | |k�r || |k�r ||7 }q�|�r2|j| ||f� ||| } }}q�W |�r\|j| ||f� |j||df� tt t j |��| _ | j S )a Return list of triples describing matching subsequences. Each triple is of the form (i, j, n), and means that a[i:i+n] == b[j:j+n]. The triples are monotonically increasing in i and in j.

IOW, adjacent triples never describe adjacent equal blocks. The last triple is a dummy, (len(a), len(b), 0), and is the only triple with n==0. >>> s = SequenceMatcher(None, "abxcd", "abcd") >>> list(s.get_matching_blocks()) [Match(a=0, b=0, size=2), Match(a=3, b=2, size=2), Match(a=5, b=4, size=0)] Nr ) r r. r r �popr= r) �sort�list�mapr �_make)r �la�lbZqueuer r7 r8 r9 r: r0 r; r< �x�i1�j1Zk1Z non_adjacent�i2�j2Zk2r r r �get_matching_blocks� s8 z#SequenceMatcher.get_matching_blocksc C s� | j dk r| j S d }}g | _ }x�| j� D ]�\}}}d}||k rP||k rPd}n||k r^d}n ||k rjd}|r�|j|||||f� || || }}|r,|jd||||f� q,W |S )a[ Return list of 5-tuples describing how to turn a into b.

The tags are strings, with these meanings: 'replace': a[i1:i2] should be replaced by b[j1:j2] 'delete': a[i1:i2] should be deleted. Note that j1==j2 in this case.

Differ uses SequenceMatcher both to compare sequences of lines, and to compare sequences of characters within similar (near-matching) lines. Each line of a Differ delta begins with a two-letter code: '- ' line unique to sequence 1 '+ ' line unique to sequence 2 ' ' line common to both sequences '? ' line not present in either input sequence Lines beginning with '? ' attempt to guide the eye to intraline differences, and were not present in either input sequence. These lines can be confusing if the sequences contain tab characters. Note that Differ makes no claim to produce a *minimal* diff. To the contrary, minimal diffs are often counter-intuitive, because they synch up anywhere possible, sometimes accidental matches 100 pages apart. Restricting synch points to contiguous matches preserves some notion of locality, at the occasional cost of producing a longer diff. Example: Comparing two texts. First we set up the texts, sequences of individual single-line strings ending with newlines (such sequences can also be obtained from the `readlines()` method of file-like objects): >>> text1 = ''' 1. Beautiful is better than ugly. ... 2. Explicit is better than implicit. ... 3. Simple is better than complex. ... 4. Complex is better than complicated. ... '''.splitlines(keepends=True) >>> len(text1) 4 >>> text1[0][-1] '\n' >>> text2 = ''' 1. Beautiful is better than ugly. ... 3. Simple is better than complex. ... 4. Complicated is better than complex. ... 5. Flat is better than nested. ... '''.splitlines(keepends=True) Next we instantiate a Differ object: >>> d = Differ() Note that when instantiating a Differ object we may pass functions to filter out line and character 'junk'. See Differ.__init__ for details. Finally, we compare the two: >>> result = list(d.compare(text1, text2)) 'result' is a list of strings, so let's pretty-print it: >>> from pprint import pprint as _pprint >>> _pprint(result) [' 1. Beautiful is better than ugly.\n', '- 2. Explicit is better than implicit.\n', '- 3. Simple is better than complex.\n', '+ 3. Simple is better than complex.\n', '? ++\n', '- 4. Complex is better than complicated.\n', '? ^ ---- ^\n', '+ 4. Complicated is better than complex.\n', '? ++++ ^ ^\n', '+ 5. Flat is better than nested.\n'] As a single multi-line string it looks like this: >>> print(''.join(result), end="") 1. Beautiful is better than ugly. - 2. Explicit is better than implicit. - 3. Simple is better than complex. + 3. Simple is better than complex. ? ++ - 4. Complex is better than complicated. ? ^ ---- ^ + 4. Complicated is better than complex. ? ++++ ^ ^ + 5. Flat is better than nested. Methods: __init__(linejunk=None, charjunk=None) Construct a text differencer, with optional filters. compare(a, b) Compare two sequences of lines; generate the resulting delta. Nc C s || _ || _dS )a� Construct a text differencer, with optional filters. The two optional keyword parameters are for filter functions: - `linejunk`: A function that should accept a single string argument, and return true iff the string is junk. The module-level function `IS_LINE_JUNK` may be used to filter out lines without visible characters, except for at most one splat ('#'). It is recommended to leave linejunk None; the underlying SequenceMatcher class has an adaptive notion of "noise" lines that's better than any static definition the author has ever been able to craft. - `charjunk`: A function that should accept a string of length 1. The module-level function `IS_CHARACTER_JUNK` may be used to filter out whitespace characters (a blank or tab; **note**: bad idea to include newline in this!). Use of IS_CHARACTER_JUNK is recommended.

Each sequence must contain individual single-line strings ending with newlines. Such sequences can be obtained from the `readlines()` method of file-like objects. The delta generated also consists of newline- terminated strings, ready to be printed as-is via the writeline() method of a file-like object. Example: >>> print(''.join(Differ().compare('one\ntwo\nthree\n'.splitlines(True), ...

Unified diffs are a compact way of showing line changes and a few lines of context. The number of context lines is set by 'n' which defaults to three. By default, the diff control lines (those with ---, +++, or @@) are created with a trailing newline. This is helpful so that inputs created from file.readlines() result in diffs that are suitable for file.writelines() since both the inputs and outputs have trailing newlines. For inputs that do not have trailing newlines, set the lineterm argument to "" so that the output will be uniformly newline free. The unidiff format normally has a header for filenames and modification times. Any or all of these may be specified using strings for 'fromfile', 'tofile', 'fromfiledate', and 'tofiledate'. The modification times are normally expressed in the ISO 8601 format. Example: >>> for line in unified_diff('one two three four'.split(), ... 'zero one tree four'.split(), 'Original', 'Current', ...

At the end of the HTML generation, the tab characters will be replaced with a nonbreakable space. c s6 | j dd�} | j� j�} | j dd�} | j dd�jd�S )Nrr r� r� r� )rK � expandtabsr� r� )rk )r r r � expand_tabs� s z2HtmlDiff._tab_newline_replace.<locals>.expand_tabsc s g | ] }� |��qS r r )rZ rk )r� r r re s z1HtmlDiff._tab_newline_replace.<locals>.<listcomp>c s g | ] }� |��qS r r )rZ rk )r� r r re s r )r r� r� r )r� r r �_tab_newline_replace� s z HtmlDiff._tab_newline_replacec C s |s|j ||f� dS t|�}| j}||ksB||jd�d |krT|j ||f� dS d}d}d}xd||k r�||k r�|| dkr�|d7 }|| }|d7 }qb|| dkr�|d7 }d}qb|d7 }|d7 }qbW |d|� } ||d� } |r�| d } d| | } |j || f� | j|d| � dS ) a� Builds list of text lines by splitting text lines at wrap point This function will determine if the input text line needs to be wrapped (split) into separate lines.

If pathname is a package directory, search the directory and all package subdirectories recursively for all *.py and enter the modules into the archive. If pathname is a plain directory, listdir *.py and enter all modules. Else, pathname must be a Python *.py file and the module will be put into the archive. Added modules are always module.pyc. This method will compile the module.py into module.pyc if necessary. If filterfunc(pathname) is given, it is called with every argument.

The .encode()/.decode() methods may use different error handling schemes by providing the errors argument. These string values are predefined: 'strict' - raise a ValueError error (or a subclass) 'ignore' - ignore the character and continue with the next 'replace' - replace with a suitable replacement character; Python will use the official U+FFFD REPLACEMENT CHARACTER for the builtin Unicode codecs on decoding and '?' on encoding. 'surrogateescape' - replace with private code points U+DCnn. 'xmlcharrefreplace' - Replace with the appropriate XML character reference (only for encoding). 'backslashreplace' - Replace with backslashed escape sequences. 'namereplace' - Replace with \N{...} escape sequences (only for encoding). The set of allowed values can be extended via register_error. �strictc C s t �dS )a# Encodes the object input and returns a tuple (output object, length consumed). errors defines the error handling to apply.

The decoder can modify this setting as appropriate. The default value -1 indicates to read and decode as much as possible. size is intended to prevent having to decode huge files in one step.

They use the complete set of APIs returned by the codecs.lookup() function to implement their task. Data written to the StreamRecoder is first decoded into an intermediate format (depending on the "decode" codec) and then written to the underlying stream using an instance of the provided Writer class.

Note: The wrapped version will only accept the object format defined by the codecs, i.e. Unicode objects for most builtin codecs. Output is also codec dependent and will usually be Unicode as well. Underlying encoded files are always opened in binary mode. The default file mode is 'r', meaning to open the file in read mode. encoding specifies the encoding which is to be used for the file. errors may be given to define the error handling. It defaults to 'strict' which causes ValueErrors to be raised in case an encoding error occurs. buffering has the same meaning as for the builtin open() API. It defaults to line buffered. The returned wrapped file object provides an extra attribute .encoding which allows querying the used encoding. This attribute is only available if an encoding was specified as parameter.

If file_encoding is not given, it defaults to data_encoding. errors may be given to define the error handling. It defaults to 'strict' which causes ValueErrors to be raised in case an encoding error occurs.

This class adds support for 'chat' style protocols - where one side sends a 'command', and the other sends a response (examples would be the common internet protocols - smtp, nntp, ftp, etc..). The handle_read() method looks at the input stream for the current 'terminator' (usually '\r\n' for single-line responses, '\r\n.\r\n' for multi-line output), calling self.found_terminator() on its receipt. for example: Say you build an async nntp client using this class. At the start of the connection, you'll have self.terminator set to '\r\n', in order to process the single-line greeting. Just before issuing a 'LIST' command you'll set it to '\r\n.\r\n'.

This module provides regular expression matching operations similar to those found in Perl. It supports both 8-bit and Unicode strings; both the pattern and the strings being processed can contain null bytes and characters outside the US ASCII range. Regular expressions can contain both special and ordinary characters. Most ordinary characters, like "A", "a", or "0", are the simplest regular expressions; they simply match themselves. You can concatenate ordinary characters, so last matches the string 'last'. The special characters are: "." Matches any character except a newline. "^" Matches the start of the string. "$" Matches the end of the string or just before the newline at the end of the string. "*" Matches 0 or more (greedy) repetitions of the preceding RE. Greedy means that it will match as many repetitions as possible. "+" Matches 1 or more (greedy) repetitions of the preceding RE. "?" Matches 0 or 1 (greedy) of the preceding RE. *?,+?,?? Non-greedy versions of the previous three special characters. {m,n} Matches from m to n repetitions of the preceding RE. {m,n}? Non-greedy version of the above. "\\" Either escapes special characters or signals a special sequence. [] Indicates a set of characters. A "^" as the first character indicates a complementing set. "|" A|B, creates an RE that will match either A or B. (...) Matches the RE inside the parentheses. The contents can be retrieved or matched later in the string. (?aiLmsux) Set the A, I, L, M, S, U, or X flag for the RE (see below). (?:...) Non-grouping version of regular parentheses. (?P<name>...) The substring matched by the group is accessible by name. (?P=name) Matches the text matched earlier by the group named name. (?#...) A comment; ignored. (?=...) Matches if ... matches next, but doesn't consume the string. (?!...) Matches if ... doesn't match next. (?<=...) Matches if preceded by ... (must be fixed length). (?<!...) Matches if not preceded by ... (must be fixed length). (?(id/name)yes|no) Matches yes pattern if the group with id/name matched, the (optional) no pattern otherwise. The special sequences consist of "\\" and a character from the list below. If the ordinary character is not on the list, then the resulting RE will match the second character. \number Matches the contents of the group of the same number. \A Matches only at the start of the string. \Z Matches only at the end of the string. \b Matches the empty string, but only at the start or end of a word. \B Matches the empty string, but not at the start or end of a word. \d Matches any decimal digit; equivalent to the set [0-9] in bytes patterns or string patterns with the ASCII flag. In string patterns without the ASCII flag, it will match the whole range of Unicode digits. \D Matches any non-digit character; equivalent to [^\d]. \s Matches any whitespace character; equivalent to [ \t\n\r\f\v] in bytes patterns or string patterns with the ASCII flag. In string patterns without the ASCII flag, it will match the whole range of Unicode whitespace characters. \S Matches any non-whitespace character; equivalent to [^\s]. \w Matches any alphanumeric character; equivalent to [a-zA-Z0-9_] in bytes patterns or string patterns with the ASCII flag. In string patterns without the ASCII flag, it will match the range of Unicode alphanumeric characters (letters plus digits plus underscore). With LOCALE, it will match the set [0-9_] plus characters defined as letters for the current locale. \W Matches the complement of \w. \\ Matches a literal backslash. This module exports the following functions: match Match a regular expression pattern to the beginning of a string. fullmatch Match a regular expression pattern to all of a string. search Search a string for the presence of a pattern. sub Substitute occurrences of a pattern found in a string. subn Same as sub, but also return the number of substitutions made. split Split a string by the occurrences of a pattern. findall Find all occurrences of a pattern in a string. finditer Return an iterator yielding a match object for each match. compile Compile a pattern into a RegexObject. purge Clear the regular expression cache. escape Backslash all non-alphanumerics in a string. Some of the functions in this module takes flags as optional parameters: A ASCII For string patterns, make \w, \W, \b, \B, \d, \D match the corresponding ASCII character categories (rather than the whole Unicode categories, which is the default). For bytes patterns, this flag is the only available behaviour and needn't be specified. I IGNORECASE Perform case-insensitive matching. L LOCALE Make \w, \W, \b, \B, dependent on the current locale. M MULTILINE "^" matches the beginning of lines (after a newline) as well as the string. "$" matches the end of lines (before a newline) as well as the end of the string. S DOTALL "." matches any character at all, including the newline. X VERBOSE Ignore whitespace and comments for nicer looking RE's. U UNICODE For compatibility only. Ignored for string patterns (it is the default), and forbidden for bytes patterns.

Usage:: T = TypeVar('T') # Can be anything A = TypeVar('A', str, bytes) # Must be str or bytes Type variables exist primarily for the benefit of static type checkers. They serve as the parameters for generic types as well as for generic function definitions. See class Generic for more information on generic types. Generic functions work as follows: def repeat(x: T, n: int) -> List[T]: '''Return a list containing n references to x.''' return [x]*n def longest(x: A, y: A) -> A: '''Return the longest of two strings.''' return x if len(x) >= len(y) else y The latter example's signature is essentially the overloading of (str, str) -> str and (bytes, bytes) -> bytes. Also note that if the arguments are instances of some subclass of str, the return type is still plain str. At runtime, isinstance(x, T) and issubclass(C, T) will raise TypeError. Type variables defined with covariant=True or contravariant=True can be used do declare covariant or contravariant generic types. See PEP 484 for more details. By default generic types are invariant in all type variables. Type variables can be introspected. e.g.: T.__name__ == 'T' T.__constraints__ == () T.__covariant__ == False T.__contravariant__ = False A.__constraints__ == (str, bytes) rA � __bound__r� � __covariant__�__contravariant__NF)�bound� covariant� contravariantc s� t � j|f|�|||d�� || _|r2|r2td��t|�| _t|�| _|rZ|d k rZtd��|rrt|�dkrrtd��d� t � fdd�|D ��| _ |r�t |d �| _ nd | _ d S ) N)r� r� r� z"Bivariant types are not supported.z-Constraints cannot be combined with bound=...rK z"A single constraint is not allowedz:TypeVar(name, constraint, ...): constraints must be types.c 3 s | ]}t |� �V qd S )N)r} )�.0r� )r� rC rD � <genexpr> s z#TypeVar.__init__.<locals>.<genexpr>zBound must be a type.) rT r^ rA � ValueError�boolr� r� rP rk rn r� r} r� )r[ rW r� r� r� Z constraints)rZ )r� rD r^ � s zTypeVar.__init__c C s | |kr|j | � d S )N)�append)r[ rb rC rC rD rc s zTypeVar._get_type_varsc C s& | j r d}n| jrd}nd}|| j S )N�+�-�~)r� r� rA )r[ �prefixrC rC rD rf s zTypeVar.__repr__c C s t d��d S )Nz0Type variables cannot be used with isinstance().)rP )r[ �instancerC rC rD r� s zTypeVar.__instancecheck__c C s t d��d S )Nz0Type variables cannot be used with issubclass().)rP )r[ rV rC rC rD r� s zTypeVar.__subclasscheck__)rA r� r� r� r� ) rA rd r@ rg rq r^ rc rf r� r� ri rC rC )rZ rD r � s ( �T�KT�VT�T_co)r� �V_co�VT_co�T_contra)r� c C sd |dkr g }t | d�r0t| ttf�r0| j||�S t| t�r`x$t|�D ]\}}| |krD|| S qDW | S )z�An internal helper function: replace arg if it is a type variable found in tvars with corresponding substitution from args or with corresponding substitution sub-tree if arg is a generic type.

This is often the same as obj.__annotations__, but it handles forward references encoded as string literals, and if necessary adds Optional[t] if a default value equal to None is set. The argument may be a module, class, method, or function. The annotations are returned as a dictionary. For classes, annotations include also inherited members. TypeError is raised if the argument is not of a type that can contain annotations, and an empty dictionary is returned if no annotations are present. BEWARE -- the behavior of globalns and localns is counterintuitive (unless you are familiar with how eval() and exec() work). The search order is locals first, then globals. - If no dict arguments are passed, an attempt is made to use the globals from obj (or the respective module's globals for classes), and these are also used as the locals. If the object does not appear to have globals, an empty dictionary is used. - If one dict argument is passed, it is used for both globals and locals. - If two dict arguments are passed, they specify globals and locals, respectively. �__no_type_check__N�__annotations__� __globals__z1{!r} is not a module, class, method, or function.)r� rl ro �reversedr� r> �modulesrd r �get�itemsrm rG ra r� � ModuleType�_allowed_typesrP r r! r� r ) r� r_ r` Zhintsr� Z base_globalsZannrW r� r rC rC rD r7 � sV c C s� t | t�r|| jj� }x0| jj� D ]"\}}|| j| f kr |j|� q W x4|j� D ](}t |tj �rfd|_ t |t�rPt |� qPW y d| _ W n t k r� Y nX | S )aI Decorator to indicate that annotations are not type hints.

A "shelf" is a persistent, dictionary-like object. The difference with dbm databases is that the values (not the keys!) in a shelf can be essentially arbitrary Python objects -- anything that the "pickle" module can handle. This includes most class instances, recursive data types, and objects containing lots of shared sub-objects. The keys are ordinary strings. To summarize the interface (key is a string, data is an arbitrary object): import shelve d = shelve.open(filename) # open, with (g)dbm filename -- no suffix d[key] = data # store data at key (overwrites old data if # using an existing key) data = d[key] # retrieve a COPY of the data at key (raise # KeyError if no such key) -- NOTE that this # access returns a *copy* of the entry! del d[key] # delete data stored at key (raises KeyError # if no such key) flag = key in d # true if the key exists list = d.keys() # a list of all existing keys (slow!) d.close() # close it Dependent on the implementation, closing a persistent dictionary may or may not be necessary to flush changes to disk. Normally, d[key] returns a COPY of the entry. This needs care when mutable entries are mutated: for example, if d[key] is a list, d[key].append(anitem) does NOT modify the entry d[key] itself, as stored in the persistent mapping -- it only modifies the copy, which is then immediately discarded, so that the append has NO effect whatsoever. To append an item to d[key] in a way that will affect the persistent mapping, use: data = d[key] data.append(anitem) d[key] = data To avoid the problem with mutable entries, you may pass the keyword argument writeback=True in the call to shelve.open. When you use: d = shelve.open(filename, writeback=True) then d keeps a cache of all entries you access, and writes them all back to the persistent mapping when you call d.close(). This ensures that such usage as d[key].append(anitem) works as intended. However, using keyword argument writeback=True may consume vast amount of memory for the cache, and it may make d.close() very slow, if you access many of d's entries after opening it in this way: d has no way to check which of the entries you access are mutable and/or which ones you actually mutate, so it must cache, and write back at close, all of the entries that you access. You can call d.sync() to write back all the entries in the cache, and empty the cache (d.sync() also synchronizes the persistent dictionary on disk, if feasible). � )�Pickler� Unpickler)�BytesION�Shelf� BsdDbShelf�DbfilenameShelf�openc @ s8 e Zd ZdZdd� Ze Z Z Z Z Z Z dd� Z dS )� _ClosedDictz>Marker for a closed dict.

This module provides a class for reading and writing compressed files, classes for incremental (de)compression, and convenience functions for one-shot (de)compression. These classes and functions support both the XZ and legacy LZMA container formats, as well as raw compressed data streams.

An LZMAFile can act as a wrapper for an existing file object, or refer directly to a named file on disk. Note that LZMAFile provides a *binary* file interface - data read is returned as bytes, and data to be written must be given as bytes.

These can equivalently be given as "rb", "wb", "xb" and "ab" respectively. format specifies the container format to use for the file. If mode is "r", this defaults to FORMAT_AUTO. Otherwise, the default is FORMAT_XZ. check specifies the integrity check to use. This argument can only be used when opening a file for writing. For FORMAT_XZ, the default is CHECK_CRC64. FORMAT_ALONE and FORMAT_RAW do not support integrity checks - for these formats, check must be omitted, or be CHECK_NONE. When opening a file for reading, the *preset* argument is not meaningful, and should be omitted. The *filters* argument should also be omitted, except when format is FORMAT_RAW (in which case it is required). When opening a file for writing, the settings used by the compressor can be specified either as a preset compression level (with the *preset* argument), or in detail as a custom filter chain (with the *filters* argument). For FORMAT_XZ and FORMAT_ALONE, the default is to use the PRESET_DEFAULT preset level. For FORMAT_RAW, the caller must always specify a filter chain; the raw compressor does not support preset compression levels. preset (if provided) should be an integer in the range 0-9, optionally OR-ed with the constant PRESET_EXTREME. filters (if provided) should be a sequence of dicts. Each dict should have an entry for "id" indicating ID of the filter, plus additional entries for options to the filter.

As the example above shows, the add_argument() method is used to populate the parser with actions for optional and positional arguments. Then the parse_args() method is invoked to convert the args at the command-line into an object with attributes. - ArgumentError -- The exception raised by ArgumentParser objects when there are errors with the parser's actions. Errors raised while parsing the command-line are caught by ArgumentParser and emitted as command-line messages. - FileType -- A factory for defining types of files to be created. As the example above shows, instances of FileType are typically passed as the type= argument of add_argument() calls. - Action -- The base class for parser actions. Typically actions are selected by passing strings like 'store_true' or 'append_const' to the action= argument of add_argument(). However, for greater customization of ArgumentParser actions, subclasses of Action may be defined and passed as the action= argument. - HelpFormatter, RawDescriptionHelpFormatter, RawTextHelpFormatter, ArgumentDefaultsHelpFormatter -- Formatter classes which may be passed as the formatter_class= argument to the ArgumentParser constructor. HelpFormatter is the default, RawDescriptionHelpFormatter and RawTextHelpFormatter tell the parser not to change the formatting for help text, and ArgumentDefaultsHelpFormatter adds information about argument defaults to the help. All other classes in this module are considered implementation details. (Also note that HelpFormatter and RawDescriptionHelpFormatter are only considered public as object names -- the API of the formatter objects is still considered an implementation detail.) z1.1�ArgumentParser� ArgumentError�ArgumentTypeError�FileType� HelpFormatter� ArgumentDefaultsHelpFormatter�RawDescriptionHelpFormatter�RawTextHelpFormatter�MetavarTypeHelpFormatter� Namespace�Action� ONE_OR_MORE�OPTIONAL�PARSER� REMAINDER�SUPPRESS� ZERO_OR_MORE� N)�gettext�ngettextz ==SUPPRESS==�?�*�+zA...z...Z_unrecognized_argsc @ s( e Zd ZdZdd� Zdd� Zdd� ZdS ) �_AttributeHoldera Abstract base class that provides __repr__.

Action objects are used by an ArgumentParser to represent the information needed to parse a single argument from one or more strings from the command line. The keyword arguments to the Action constructor are also all attributes of Action instances. Keyword Arguments: - option_strings -- A list of command-line option strings which should be associated with this action. - dest -- The name of the attribute to hold the created object(s) - nargs -- The number of command-line arguments that should be consumed. By default, one argument will be consumed and a single value will be produced. Other values include: - N (an integer) consumes N arguments (and produces a list) - '?' consumes zero or one arguments - '*' consumes zero or more arguments (and produces a list) - '+' consumes one or more arguments (and produces a list) Note that the difference between the default and nargs=1 is that with the default, a single value will be produced, while with nargs=1, a list containing a single value will be produced. - const -- The value to be produced if the option is specified and the option uses an action that takes no values. - default -- The value to be produced if the option is not specified. - type -- A callable that accepts a single string argument, and returns the converted value. The standard Python types str, int, float, and complex are useful examples of such callables. If None, str is used. - choices -- A container of values that should be allowed. If not None, after a command-line argument has been converted to the appropriate type, an exception will be raised if it is not a member of this collection. - required -- True if the action must always be specified at the command line. This is only meaningful for optional command-line arguments. - help -- The help string describing the argument. - metavar -- The name to be used for the option's argument with the help string.

At the Python interactive prompt, calling help(thing) on a Python object documents the object, and calling help() starts up an interactive help session. Or, at the shell command line outside of Python: Run "pydoc <name>" to show documentation on something. <name> may be the name of a function, module, package, or a dotted reference to a class or function within a module or module in a package. If the argument contains a path segment delimiter (e.g. slash on Unix, backslash on Windows) it is treated as the path to a Python source file. Run "pydoc -k <keyword>" to search for a keyword in the synopsis lines of all available modules. Run "pydoc -p <port>" to start an HTTP server on the given port on the local machine. Port number 0 can be used to get an arbitrary unused port. Run "pydoc -b" to start an HTTP server on an arbitrary unused port and open a Web browser to interactively browse documentation. The -p option can be used with the -b option to explicitly specify the server port. Run "pydoc -w <name>" to write out the HTML documentation for a module to a file named "<name>.html". Module docs for core modules are assumed to be in https://docs.python.org/X.Y/library/ This can be overridden by setting the PYTHONDOCS environment variable to a different URL or to a local directory containing the Library Reference Manual pages. �helpzKa-Ping Yee <ping@lfw.org>z26 February 2001z�Guido van Rossum, for an excellent programming language.

Instantiate with: IMAP4([host[, port]]) host - host's name (default: localhost); port - port number (default: standard IMAP4 port). All IMAP4rev1 commands are supported by methods of the same name (in lower-case). All arguments to commands are converted to strings, except for AUTHENTICATE, and the last argument to APPEND which is passed as an IMAP4 literal. If necessary (the string contains any non-printing characters or white-space and isn't enclosed with either parentheses or double quotes) each string is quoted. However, the 'password' argument to the LOGIN command is always quoted. If you want to avoid having an argument string quoted (eg: the 'flags' argument to STORE) then enclose the string in parentheses (eg: "(\Deleted)"). Each command returns a tuple: (type, [data, ...]) where 'type' is usually 'OK' or 'NO', and 'data' is either the text from the tagged response, or untagged results from command. Each 'data' is either a string, or a tuple. If a tuple, then the first part is the header of the response, and the second part contains the data (ie: 'literal' value). Errors raise the exception class <instance>.error("<reason>"). IMAP4 server errors raise <instance>.abort("<reason>"), which is a sub-class of 'error'. Mailbox status changes from READ-WRITE to READ-ONLY raise the exception class <instance>.readonly("<reason>"), which is a sub-class of 'abort'. "error" exceptions imply a program error. "abort" exceptions imply the connection should be reset, and the command re-tried. "readonly" exceptions imply the command should be re-tried. Note: to use this module, you must read the RFCs pertaining to the IMAP4 protocol, as the semantics of the arguments to each IMAP4 command are left to the invoker, not to mention the results. Also, most IMAP servers implement a sub-set of the commands available here. c @ s e Zd ZdS )z IMAP4.errorN)�__name__� __module__� __qualname__� r< r< � /usr/lib64/python3.6/imaplib.py�error� s r> c @ s e Zd ZdS )z IMAP4.abortN)r9 r: r; r< r< r< r= �abort� s r? c @ s e Zd ZdS )zIMAP4.readonlyN)r9 r: r; r< r< r< r= �readonly� s r@ � c C s� t | _d| _d | _i | _i | _d| _d| _d| _d| _ | j � | j ||� y | j � W n8 t k r� y | j� W n tk r� Y nX � Y nX d S )Nr rA Fr )�Debug�debug�state�literal�tagged_commands�untagged_responses�continuation_response� is_readonly�tagnum�_tls_established� _mode_ascii�open�_connect� Exception�shutdown�OSError)�self�host�portr< r< r= �__init__� s& zIMAP4.__init__c C s0 d| _ d| _tjttj�| _tjttj�| _d S )NF�ascii) � utf8_enabled� _encoding�re�compile�_Literal�ASCII�Literal�_Untagged_status�Untagged_status)rR r< r< r= rL � s zIMAP4._mode_asciic C s( d| _ d| _tjt�| _tjt�| _d S )NTzutf-8)rW rX rY rZ r[ r] r^ r_ )rR r< r< r= � _mode_utf8� s zIMAP4._mode_utf8c C s� t tjdd��| _tjd| j d tj�| _d| _d| _ i | _ | j dkrf| j dt � | j d | j � | j� | _d | jkr�d | _n d | jkr�d | _n | j| j��| j� | j dkr�| j d| jf � x tD ]}|| jkr�q�|| _d S W | jd��d S )Ni i�� s (?P<tag>s" \d+) (?P<type>[A-Z]+) (?P<data>.*)� r � zimaplib version %sz new IMAP4 connection, tag=%sZPREAUTHr �OKr � zCAPABILITIES: %rzserver not IMAP4 compliant)r �randomZrandint�tagprerY rZ r\ �tagre� _cmd_log_len� _cmd_log_idx�_cmd_logrC �_mesg� __version__� _get_responseZwelcomerG rD r> �_get_capabilities� capabilities�AllowedVersions�PROTOCOL_VERSION)rR �versionr< r< r= rN � s0 zIMAP4._connectc C s& |t krt| |j� �S td| ��d S )NzUnknown IMAP4 command: '%s')�Commands�getattr�lower�AttributeError)rR �attrr< r< r= � __getattr__ s zIMAP4.__getattr__c C s | S )Nr< )rR r< r< r= � __enter__ s zIMAP4.__enter__c G s& y | j � W n tk r Y nX d S )N)�logoutrQ )rR �argsr< r< r= �__exit__ s zIMAP4.__exit__c C s | j s d n| j }tj|| jf�S )N)rS �socketZcreate_connectionrT )rR rS r< r< r= �_create_socket s zIMAP4._create_socketc C s( || _ || _| j� | _| jjd�| _dS )z�Setup connection to remote server on "host:port" (default: localhost:standard IMAP4 port).

Implements temporary breakpoints, ignore counts, disabling and (re)-enabling, and conditionals. Breakpoints are indexed by number through bpbynumber and by the file,line tuple using bplist. The former points to a single instance of class Breakpoint.

Parse enough of a Python file to recognize imports and class and method definitions, and to find out the superclasses of a class. The interface consists of a single function: readmodule_ex(module [, path]) where module is the name of a Python module, and path is an optional list of directories where the module is to be searched. If present, path is prepended to the system search path sys.path. The return value is a dictionary. The keys of the dictionary are the names of the classes defined in the module (including classes that are defined via the from XXX import YYY construct). The values are class instances of the class Class defined here. One special key/value pair is present for packages: the key '__path__' has a list as its value which contains the package search path. A class is described by the class Class in this module. Instances of this class have the following instance variables: module -- the module name name -- the name of the class super -- a list of super classes (Class instances) methods -- a dictionary of methods file -- the file in which the class was defined lineno -- the line in the file on which the class statement occurred The dictionary of methods uses the method names as keys and the line numbers on which the method was defined as values. If the name of a super class is not recognized, the corresponding entry in the list of super classes is not a class instance but a string giving the name of the super class. Since import statements are recognized and imported modules are scanned as well, this shouldn't happen often. A function is described by the class Function in this module. Instances of this class have the following instance variables: module -- the module name name -- the name of the class file -- the file in which the class was defined lineno -- the line in the file on which the class statement occurred � N)�NAME�DEDENT�OP� readmodule� readmodule_ex�Class�Functionc s( e Zd ZdZ� fdd�Zdd� Z� ZS )r z"Class to represent a Python class.c s4 || _ || _|d krg }|| _i | _|| _|| _d S )N)�module�name�super�methods�file�lineno)�selfr r r r r )� __class__� � /usr/lib64/python3.6/pyclbr.py�__init__7 s zClass.__init__c C s || j |< d S )N)r )r r r r r r � _addmethodA s zClass._addmethod)�__name__� __module__� __qualname__�__doc__r r � __classcell__r r )r r r 5 s c @ s e Zd ZdZdd� ZdS )r z.Class to represent a top-level Python functionc C s || _ || _|| _|| _d S )N)r r r r )r r r r r r r r r F s zFunction.__init__N)r r r r r r r r r r D s c C s: i }x0t | |pg �j� D ]\}}t|t�r|||< qW |S )z}Backwards compatible interface.

This module tries to capture the various aspects of defining a server: For socket-based servers: - address family: - AF_INET{,6}: IP (Internet Protocol) sockets (default) - AF_UNIX: Unix domain sockets - others, e.g. AF_DECNET are conceivable (see <socket.h> - socket type: - SOCK_STREAM (reliable stream, e.g. TCP) - SOCK_DGRAM (datagrams, e.g. UDP) For request-based servers (including socket-based): - client address verification before further looking at the request (This is actually a hook for any processing that needs to look at the request before anything else, e.g. logging) - how to handle multiple requests: - synchronous (one request is handled at a time) - forking (each request is handled by a new process) - threading (each request is handled by a new thread) The classes in this module favor the server type that is simplest to write: a synchronous TCP/IP server. This is bad class design, but save some typing. (There's also the issue that a deep class hierarchy slows down method lookups.) There are five classes in an inheritance diagram, four of which represent synchronous servers of four types: +------------+ | BaseServer | +------------+ | v +-----------+ +------------------+ | TCPServer |------->| UnixStreamServer | +-----------+ +------------------+ | v +-----------+ +--------------------+ | UDPServer |------->| UnixDatagramServer | +-----------+ +--------------------+ Note that UnixDatagramServer derives from UDPServer, not from UnixStreamServer -- the only difference between an IP and a Unix stream server is the address family, which is simply repeated in both unix server classes. Forking and threading versions of each type of server can be created using the ForkingMixIn and ThreadingMixIn mix-in classes. For instance, a threading UDP server class is created as follows: class ThreadingUDPServer(ThreadingMixIn, UDPServer): pass The Mix-in class must come first, since it overrides a method defined in UDPServer! Setting the various member variables also changes the behavior of the underlying server mechanism. To implement a service, you must derive a class from BaseRequestHandler and redefine its handle() method. You can then run various versions of the service by combining one of the server classes with your request handler class. The request handler class must be different for datagram or stream services. This can be hidden by using the request handler subclasses StreamRequestHandler or DatagramRequestHandler. Of course, you still have to use your head! For instance, it makes no sense to use a forking server if the service contains state in memory that can be modified by requests (since the modifications in the child process would never reach the initial state kept in the parent process and passed to each child). In this case, you can use a threading server, but you will probably have to use locks to avoid two requests that come in nearly simultaneous to apply conflicting changes to the server state. On the other hand, if you are building e.g. an HTTP server, where all data is stored externally (e.g. in the file system), a synchronous class will essentially render the service "deaf" while one request is being handled -- which may be for a very long time if a client is slow to read all the data it has requested. Here a threading or forking server is appropriate. In some cases, it may be appropriate to process part of a request synchronously, but to finish processing in a forked child depending on the request data. This can be implemented by using a synchronous server and doing an explicit fork in the request handler class handle() method. Another approach to handling multiple simultaneous requests in an environment that supports neither threads nor fork (or where these are too expensive or inappropriate for the service) is to maintain an explicit table of partially finished requests and to use a selector to decide which request to work on next (or whether to handle a new incoming request). This is particularly important for stream services where each client can potentially be connected for a long time (if threads or subprocesses cannot be used). Future work: - Standard classes for Sun RPC (which uses either UDP or TCP) - Standard mix-in classes to implement various authentication and encryption schemes XXX Open problems: - What to do with out-of-band data?

This class is instantiated for each request to be handled. The constructor sets the instance variables request, client_address and server, and then calls the handle() method. To implement a specific service, all you need to do is to derive a class which defines a handle() method. The handle() method can find the request as self.request, the client address as self.client_address, and the server (in case it needs access to per-server information) as self.server.

The SOURCE can be the name of a directory, or a filename or a file-like object referring to an existing archive. The content of SOURCE is packed into an application archive in TARGET, which can be a filename or a file-like object. If SOURCE is a directory, TARGET can be omitted and will default to the name of SOURCE with .pyz appended. The created application archive will have a shebang line specifying that it should run with INTERPRETER (there will be no shebang line if INTERPRETER is None), and a __main__.py which runs MAIN (if MAIN is not specified, an existing __main__.py will be used). It is an error to specify MAIN for anything other than a directory source with no __main__.py, and it is an error to omit MAIN if the directory has no __main__.py.

Unless explicitly stated otherwise, the description below is true both for AIFF-C files and AIFF files. An AIFF-C file has the following structure. +-----------------+ | FORM | +-----------------+ | <size> | +----+------------+ | | AIFC | | +------------+ | | <chunks> | | | . | | | . | | | . | +----+------------+ An AIFF file has the string "AIFF" instead of "AIFC". A chunk consists of an identifier (4 bytes) followed by a size (4 bytes, big endian order), followed by the data. The size field does not include the size of the 8 byte header. The following chunk types are recognized. FVER <version number of AIFF-C defining document> (AIFF-C only). MARK <# of markers> (2 bytes) list of markers: <marker ID> (2 bytes, must be > 0) <position> (4 bytes) <marker name> ("pstring") COMM <# of channels> (2 bytes) <# of sound frames> (4 bytes) <size of the samples> (2 bytes) <sampling frequency> (10 bytes, IEEE 80-bit extended floating point) in AIFF-C files only: <compression type> (4 bytes) <human-readable version of compression type> ("pstring") SSND <offset> (4 bytes, not used by this program) <blocksize> (4 bytes, not used by this program) <sound data> A pstring consists of 1 byte length, a string of characters, and 0 or 1 byte pad to make the total length even. Usage. Reading AIFF files: f = aifc.open(file, 'r') where file is either the name of a file or an open file pointer. The open file pointer must have methods read(), seek(), and close(). In some types of audio files, if the setpos() method is not used, the seek() method is not necessary. This returns an instance of a class with the following public methods: getnchannels() -- returns number of audio channels (1 for mono, 2 for stereo) getsampwidth() -- returns sample width in bytes getframerate() -- returns sampling frequency getnframes() -- returns number of audio frames getcomptype() -- returns compression type ('NONE' for AIFF files) getcompname() -- returns human-readable version of compression type ('not compressed' for AIFF files) getparams() -- returns a namedtuple consisting of all of the above in the above order getmarkers() -- get the list of marks in the audio file or None if there are no marks getmark(id) -- get mark with the specified id (raises an error if the mark does not exist) readframes(n) -- returns at most n frames of audio rewind() -- rewind to the beginning of the audio stream setpos(pos) -- seek to the specified position tell() -- return the current position close() -- close the instance (make it unusable) The position returned by tell(), the position given to setpos() and the position of marks are all compatible and have nothing to do with the actual position in the file. The close() method is called automatically when the class instance is destroyed. Writing AIFF files: f = aifc.open(file, 'w') where file is either the name of a file or an open file pointer. The open file pointer must have methods write(), tell(), seek(), and close(). This returns an instance of a class with the following public methods: aiff() -- create an AIFF file (AIFF-C default) aifc() -- create an AIFF-C file setnchannels(n) -- set the number of channels setsampwidth(n) -- set the sample width setframerate(n) -- set the frame rate setnframes(n) -- set the number of frames setcomptype(type, name) -- set the compression type and the human-readable compression type setparams(tuple) -- set all parameters at once setmark(id, pos, name) -- add specified mark to the list of marks tell() -- return current position in output file (useful in combination with setmark()) writeframesraw(data) -- write audio frames without pathing up the file header writeframes(data) -- write audio frames and patch up the file header close() -- patch up the file header and close the output file You should set the parameters before the first writeframesraw or writeframes. The total number of frames does not need to be set, but when it is set to the correct value, the header does not have to be patched up. It is best to first set all parameters, perhaps possibly the compression type, and then write audio frames using writeframesraw. When all frames have been written, either call writeframes(b'') or close() to patch up the sizes in the header. Marks can be added anytime. If there are any marks, you must call close() after all frames have been written. The close() method is called automatically when the class instance is destroyed. When a file is opened with the extension '.aiff', an AIFF file is written, otherwise an AIFF-C file is written. This default can be changed by calling aiff() or aifc() before the first writeframes or writeframesraw. � N�Error�open�openfpc @ s e Zd ZdS )r N)�__name__� __module__� __qualname__� r r � /usr/lib64/python3.6/aifc.pyr � s l @Q E c C s6 yt jd| jd��d S t jk r0 t�Y nX d S )Nz>l� r )�struct�unpack�read�error�EOFError)�filer r r � _read_long� s r c C s6 yt jd| jd��d S t jk r0 t�Y nX d S )Nz>Lr r )r r r r r )r r r r � _read_ulong� s r c C s6 yt jd| jd��d S t jk r0 t�Y nX d S )Nz>h� r )r r r r r )r r r r � _read_short� s r c C s6 yt jd| jd��d S t jk r0 t�Y nX d S )Nz>Hr r )r r r r r )r r r r � _read_ushort� s r c C s@ t | jd��}|dkr d}n | j|�}|d@ dkr<| jd�}|S )N� r � )�ordr )r �length�data�dummyr r r � _read_string� s r g�����c C s� t | �}d}|dk r d }|d }t| �}t| �}|| koL| koLdkn rXd} n0|dkrft} n"|d }|d | td|d � } || S ) Nr r i � g i� i�?

Called internally from sysconfig with a mutable mapping containing name/value pairs parsed from the configured makefile used to build this interpreter. Returns the mapping updated as needed to reflect the environment in which the interpreter is running; in the case of a Python from a binary installer, the installed environment may be very different from the build environment, i.e. different OS levels, different built tools, different available CPU architectures. This customization is performed whenever distutils.sysconfig.get_config_vars() is first called. It may be used in environments where no compilers are present, i.e. when installing pure Python dists. Customization of compiler paths and detection of unavailable archs is deferred until the first extension module build is requested (in distutils.sysconfig.customize_compiler).

Each instance of this class manages its own queue. No multi-threading is implied; you are supposed to hack that yourself, or use a single instance per application. Each instance is parametrized with two functions, one that is supposed to return the current time, one that is supposed to implement a delay. You can implement real-time scheduling by substituting time and sleep from built-in module time, or you can implement simulated time by writing your own functions. This can also be used to integrate scheduling with STDWIN events; the delay function is allowed to modify the queue. Time can be expressed as integers or floating point numbers, as long as it is consistent. Events are specified by tuples (time, priority, action, argument, kwargs). As in UNIX, lower priority numbers mean higher priority; in this way the queue can be maintained as a priority queue. Execution of the event means calling the action function, passing it the argument sequence in "argument" (remember that in Python, multiple function arguments are be packed in a sequence) and keyword parameters in "kwargs". The action function may be an instance method so it has another way to reference private data (besides global variables). � N)� namedtuple)� monotonic� schedulerc @ s8 e Zd Zg Zdd� Zdd� Zdd� Zdd� Zd d � Zd S ) �Eventc C s | j | jf|j |jfkS )N)�time�priority)�s�o� r � /usr/lib64/python3.6/sched.py�__eq__' s z Event.__eq__c C s | j | jf|j |jfk S )N)r r )r r r r r �__lt__( s z Event.__lt__c C s | j | jf|j |jfkS )N)r r )r r r r r �__le__) s z Event.__le__c C s | j | jf|j |jfkS )N)r r )r r r r r �__gt__* s z Event.__gt__c C s | j | jf|j |jfkS )N)r r )r r r r r �__ge__+ s z Event.__ge__N) �__name__� __module__� __qualname__� __slots__r r r r r r r r r r % s r z(time, priority, action, argument, kwargszaNumeric type compatible with the return value of the timefunc function passed to the constructor.zSEvents scheduled for the same time will be executed in the order of their priority.z?Executing the event means executing action(*argument, **kwargs)zGargument is a sequence holding the positional arguments for the action.zDkwargs is a dictionary holding the keyword arguments for the action.c @ s^ e Zd Zeejfdd�Zf efdd�Zf efdd�Z dd� Z d d � Z dd d �Z e dd� �ZdS )r c C s g | _ tj� | _|| _|| _dS )zGInitialize a new instance, passing the time and delay functionsN)�_queue� threading�RLock�_lock�timefunc� delayfunc)�selfr r r r r �__init__< s zscheduler.__init__c C s@ |t kr i }t|||||�}| j� tj| j|� W dQ R X |S )z�Enter a new event in the queue at an absolute time.

If blocking is False executes the scheduled events due to expire soonest (if any) and then return the deadline of the next scheduled call in the scheduler. When there is a positive delay until the first event, the delay function is called and the event is left in the queue; otherwise, the event is removed from the queue and executed (its action function is called, passing it the argument). If the delay function returns prematurely, it is simply restarted. It is legal for both the delay function and the action function to modify the queue or to raise an exception; exceptions are not caught but the scheduler's state remains well-defined so run() may be called again. A questionable hack is added to allow other threads to run: just after an event is executed, a delay of 0 is executed, to avoid monopolizing the CPU when other threads are also runnable. r TFN)r r r r r �heappop)r Zblocking�lock�qr r �popr r r r! r" Znowr% r r r �runk s* z scheduler.runc C s: | j � | jdd� }W dQ R X tttj|gt|� ��S )z�An ordered list of upcoming events.

Formatter objects transform an abstract flow of formatting events into specific output events on writer objects. Formatters manage several stack structures to allow various properties of a writer object to be changed and restored; writers need not be able to handle relative changes nor any sort of ``change back'' operation. Specific writer properties which may be controlled via formatter objects are horizontal alignment, font, and left margin indentations. A mechanism is provided which supports providing arbitrary, non-exclusive style settings to a writer as well. Additional interfaces facilitate formatting events which are not reversible, such as paragraph separation. Writer objects encapsulate device interfaces. Abstract devices, such as file formats, are supported as well as physical devices. The provided implementations all work with abstract devices. The interface makes available mechanisms for setting the properties which formatter objects manage and inserting data into the output. � Nz"the formatter module is deprecated� )� stacklevelc @ s� e Zd ZdZd(dd�Zdd� Zdd� Zd d � Zd)d d �Zd d� Z dd� Z dd� Z dd� Z dd� Z dd� Zdd� Zdd � Zd d � Zd d � Zd!d"� Zd*d$d%�Zd+d&d'�ZdS ),� NullFormattera= A formatter which does nothing.

There are only two ways to have a program on a single processor do "more than one thing at a time". Multi-threaded programming is the simplest and most popular way to do it, but there is another very different technique, that lets you have nearly all the advantages of multi-threading, without actually using multiple threads. it's really only practical if your program is largely I/O bound. If your program is CPU bound, then pre-emptive scheduled threads are probably what you really need. Network servers are rarely CPU-bound, however. If your operating system supports the select() system call in its I/O library (and nearly all do), then you can use it to juggle multiple communication channels at once; doing other work while your I/O is taking place in the "background." Although this strategy can seem strange and complex, especially at first, it is in many ways easier to understand and control than multi-threaded programming. The module documented here solves many of the difficult problems for you, making the task of building sophisticated high-performance network servers and clients a snap. � N) �EALREADY� EINPROGRESS� EWOULDBLOCK� ECONNRESET�EINVAL�ENOTCONN� ESHUTDOWN�EISCONN�EBADF� ECONNABORTED�EPIPE�EAGAIN� errorcodec C s> y t j| �S tttfk r8 | tkr0t| S d| S X d S )NzUnknown error %s)�os�strerror� ValueError� OverflowError� NameErrorr )�err� r � /usr/lib64/python3.6/asyncore.py� _strerrorD s r c @ s e Zd ZdS )�ExitNowN)�__name__� __module__� __qualname__r r r r r L s r c C s: y | j � W n( tk r" � Y n | j� Y nX d S )N)�handle_read_event�_reraised_exceptions� handle_error)�objr r r �readQ s r c C s: y | j � W n( tk r" � Y n | j� Y nX d S )N)�handle_write_eventr r )r r r r �writeY s r" c C s: y | j � W n( tk r" � Y n | j� Y nX d S )N)�handle_expt_eventr r )r r r r � _exceptiona s r$ c C s� yX|t j@ r| j� |t j@ r&| j� |t j@ r8| j� |t jt jB t j B @ rV| j � W nh t k r� } z&|j d t kr�| j� n| j � W Y d d }~X n( tk r� � Y n | j� Y nX d S )Nr )�select�POLLINr �POLLOUTr!

There are only two ways to have a program on a single processor do "more than one thing at a time". Multi-threaded programming is the simplest and most popular way to do it, but there is another very different technique, that lets you have nearly all the advantages of multi-threading, without actually using multiple threads. it's really only practical if your program is largely I/O bound. If your program is CPU bound, then pre-emptive scheduled threads are probably what you really need. Network servers are rarely CPU-bound, however. If your operating system supports the select() system call in its I/O library (and nearly all do), then you can use it to juggle multiple communication channels at once; doing other work while your I/O is taking place in the "background." Although this strategy can seem strange and complex, especially at first, it is in many ways easier to understand and control than multi-threaded programming. The module documented here solves many of the difficult problems for you, making the task of building sophisticated high-performance network servers and clients a snap. � N) �EALREADY� EINPROGRESS� EWOULDBLOCK� ECONNRESET�EINVAL�ENOTCONN� ESHUTDOWN�EISCONN�EBADF� ECONNABORTED�EPIPE�EAGAIN� errorcodec C s> y t j| �S tttfk r8 | tkr0t| S d| S X d S )NzUnknown error %s)�os�strerror� ValueError� OverflowError� NameErrorr )�err� r � /usr/lib64/python3.6/asyncore.py� _strerrorD s r c @ s e Zd ZdS )�ExitNowN)�__name__� __module__� __qualname__r r r r r L s r c C s: y | j � W n( tk r" � Y n | j� Y nX d S )N)�handle_read_event�_reraised_exceptions� handle_error)�objr r r �readQ s r c C s: y | j � W n( tk r" � Y n | j� Y nX d S )N)�handle_write_eventr r )r r r r �writeY s r" c C s: y | j � W n( tk r" � Y n | j� Y nX d S )N)�handle_expt_eventr r )r r r r � _exceptiona s r$ c C s� yX|t j@ r| j� |t j@ r&| j� |t j@ r8| j� |t jt jB t j B @ rV| j � W nh t k r� } z&|j d t kr�| j� n| j � W Y d d }~X n( tk r� � Y n | j� Y nX d S )Nr )�select�POLLINr �POLLOUTr! �POLLPRIr# ZPOLLHUPZPOLLERRZPOLLNVAL� handle_close�OSError�args� _DISCONNECTEDr r )r �flags�er r r � readwritei s" r/ � c C sN |d kr t }|�rJg }g }g }x^t|j� �D ]N\}}|j� }|j� }|rR|j|� |rh|j rh|j|� |sp|r,|j|� q,W g | ko�| ko�|kn r�tj| � d S t j |||| �\}}}x(|D ] }|j |�}|d kr�q�t |� q�W x*|D ]"}|j |�}|d k�rq�t |� q�W x.|D ]&}|j |�}|d k�r<�q t |� �q W d S )N)� socket_map�list�items�readable�writable�append� accepting�timeZsleepr% �getr r" r$ ) �timeout�map�r�wr. �fdr Zis_rZis_wr r r �poll} sD " r? c C s� |d kr t }| d k r t| d �} tj� }|r�x^t|j� �D ]N\}}d}|j� r^|tjtjB O }|j � rx|j rx|tj O }|r:|j ||� q:W |j| �}x.|D ]&\}}|j |�}|d kr�q�t||� q�W d S )Ni� r )r1 �intr% r? r2 r3 r4 r& r( r5 r7 r' �registerr9 r/ )r: r;

Usage. Reading WAVE files: f = wave.open(file, 'r') where file is either the name of a file or an open file pointer. The open file pointer must have methods read(), seek(), and close(). When the setpos() and rewind() methods are not used, the seek() method is not necessary. This returns an instance of a class with the following public methods: getnchannels() -- returns number of audio channels (1 for mono, 2 for stereo) getsampwidth() -- returns sample width in bytes getframerate() -- returns sampling frequency getnframes() -- returns number of audio frames getcomptype() -- returns compression type ('NONE' for linear samples) getcompname() -- returns human-readable version of compression type ('not compressed' linear samples) getparams() -- returns a namedtuple consisting of all of the above in the above order getmarkers() -- returns None (for compatibility with the aifc module) getmark(id) -- raises an error since the mark does not exist (for compatibility with the aifc module) readframes(n) -- returns at most n frames of audio rewind() -- rewind to the beginning of the audio stream setpos(pos) -- seek to the specified position tell() -- return the current position close() -- close the instance (make it unusable) The position returned by tell() and the position given to setpos() are compatible and have nothing to do with the actual position in the file. The close() method is called automatically when the class instance is destroyed. Writing WAVE files: f = wave.open(file, 'w') where file is either the name of a file or an open file pointer. The open file pointer must have methods write(), tell(), seek(), and close(). This returns an instance of a class with the following public methods: setnchannels(n) -- set the number of channels setsampwidth(n) -- set the sample width setframerate(n) -- set the frame rate setnframes(n) -- set the number of frames setcomptype(type, name) -- set the compression type and the human-readable compression type setparams(tuple) -- set all parameters at once tell() -- return current position in output file writeframesraw(data) -- write audio frames without pathing up the file header writeframes(data) -- write audio frames and patch up the file header close() -- patch up the file header and close the output file You should set the parameters before the first writeframesraw or writeframes. The total number of frames does not need to be set, but when it is set to the correct value, the header does not have to be patched up. It is best to first set all parameters, perhaps possibly the compression type, and then write audio frames using writeframesraw. When all frames have been written, either call writeframes(b'') or close() to patch up the sizes in the header.

A quoted string can be embedded in an argument. 3) A double quotation mark preceded by a backslash is interpreted as a literal double quotation mark. 4) Backslashes are interpreted literally, unless they immediately precede a double quotation mark. 5) If backslashes immediately precede a double quotation mark, every pair of backslashes is interpreted as a literal backslash. If the number of backslashes is odd, the last backslash escapes the next double quotation mark as described in rule 3.

Execute the string 'cmd' in a shell with 'check_output' and return a 2-tuple (status, output). The locale encoding is used to decode the output and process newlines. A trailing newline is stripped from the output. The exit status for the command can be interpreted according to the rules for the function 'wait'. Example: >>> import subprocess >>> subprocess.getstatusoutput('ls /bin/ls') (0, '/bin/ls') >>> subprocess.getstatusoutput('cat /bin/junk') (1, 'cat: /bin/junk: No such file or directory') >>> subprocess.getstatusoutput('/bin/junk') (127, 'sh: /bin/junk: not found') >>> subprocess.getstatusoutput('/bin/kill $$') (-15, '') T)�shellru r r NrF � ���r� )r( r# r r r )r �dataZexitcodeZexr r r r& s c C s t | �d S )a% Return output (stdout or stderr) of executing cmd in a shell.

If no *abcs* are given, the algorithm works exactly like the built-in C3 linearization used for method resolution. If given, *abcs* is a list of abstract base classes that should be inserted into the resulting MRO. Unrelated ABCs are ignored and don't end up in the result. The algorithm inserts ABCs where their functionality is introduced, i.e. issubclass(cls, abc) returns True for the class itself but returns False for all its direct base classes. Implicit ABCs for a given class (either registered or inferred from the presence of a special method like __len__) are inserted directly after the last ABC explicitly listed in the MRO of said class. If two implicit ABCs end up next to each other in the resulting MRO, their ordering depends on the order of types in *abcs*. �__abstractmethods__r Nc 3 s | ]}t |� �V qd S )N)� issubclass)r@ �b)�baser r rc � s z_c3_mro.<locals>.<genexpr>c s g | ]}t |� d ��qS ))�abcs)�_c3_mro)r@ r� )r� r r rC � s z_c3_mro.<locals>.<listcomp>c s g | ]}t |� d ��qS ))r� )r� )r@ r� )r� r r rC � s c s g | ]}t |� d ��qS ))r� )r� )r@ r� )r� r r rC � s ) � enumerate�reversed� __bases__r[ rX �listr� �anyr� �remover� ) rB r� �i�boundary�explicit_bases�abstract_bases� other_bases�explicit_c3_mros�abstract_c3_mros� other_c3_mrosr )r� r� r r� ~ s( r� c s� t �j�� � �fdd���fdd��D ���fdd���fdd��D ��t ���g }x��D ]�}g }x<|j� D ]0}|� krlt�|�rl|j�fdd�|jD �� qlW |s�|j|� qZ|jtd d � x,|D ]$}x |D ]}||kr�|j|� q�W q�W qZW t�|d �S ) z�Calculates the method resolution order for a given class *cls*.

Even though this function is called initlog(), you should always use log(); log is a variable that is set either to initlog (initially), to dolog (once the log file has been opened), or to nolog (when logging is disabled). The first argument is a format string; the remaining arguments (if any) are arguments to the % operator, so e.g. log("%s: %s", "a", "b") will write "a: b" to the log file, followed by a newline. If the global logfp is not None, it should be a file object to which log data is written. If the global logfp is None, the global logfile may be a string giving a filename to open, in append mode. This file should be world writable!!!

Arguments: fp : input file pdict: dictionary containing other parameters of content-type header Returns a dictionary just like parse_qs(): keys are the field names, each value is a list of values for that field. This is easy to use but not much good if you are expecting megabytes to be uploaded -- in that case, use the FieldStorage class instead which is much more flexible. Note that content-type is the raw, unparsed contents of the content-type header. XXX This does not parse nested multipart parts -- use FieldStorage for that. XXX This should really be subsumed by FieldStorage altogether -- no point in having two implementations of the same parsing algorithm. Also, FieldStorage protects itself better against certain DoS attacks by limiting the size of the data read in one chunk. The API here does not support that kind of protection. This also affects parse() since it can call parse_multipart(). r N� �boundaryz&Invalid boundary in multipart form: %rs --r3 zcontent-lengthz Maximum content length exceededrH s � zcontent-dispositionz form-data�name���rN ���rO rN rN rN )Z http.client�valid_boundaryr; ZclientZ parse_headers�getr9 r: r< �readline� startswith�rstrip�append�joinr )r@ rE ZhttprK ZnextpartZlastpartZpartdict� terminator�bytes�data�headersrF �lines�line�keyZparamsrM r" r" r# r � s| c c s� x�| d d� dkr�| dd � } | j d�}x<|dkrd| jdd|�| jdd|� d rd| j d|d �}q*W |dk rvt| �}| d |� }|j� V | |d � } qW d S )Nr3 �;r �"z\"rH )�find�count�len�strip)�s�end�fr" r" r# � _parseparam/ s * rg c C s� t d| �}|j� }i }x�|D ]�}|jd�}|dkr |d|� j� j� }||d d� j� }t|�dkr�|d |d ko�dkn r�|dd � }|jdd �jd d�}|||< q W ||fS ) zfParse a Content-type like header.

This class provides naming, typing, files stored on disk, and more. At the top level, it is accessible like a dictionary, whose keys are the field names. (Note: None can occur as a field name.) The items are either a Python list (if there's multiple values) or another FieldStorage or MiniFieldStorage object. If it's a single object, it has the following attributes: name: the field name, if specified; otherwise None filename: the filename, if specified; otherwise None; this is the client side filename, *not* the file name on which it is stored (that's a temporary file you don't deal with) value: the value as a *string*; for file uploads, this transparently reads the file every time you request the value and returns *bytes* file: the file(-like) object from which you can read the data *as bytes* ; None if the data is stored a simple string type: the content-type, or None if not specified type_options: dictionary of options specified on the content-type line disposition: content-disposition, or None if not specified disposition_options: dictionary of corresponding options headers: a dictionary(-like) object (sometimes email.message.Message or a subclass thereof) containing *all* headers The class is subclassable, mostly for the purpose of overriding the make_file() method, which is called internally to come up with a file open for reading and writing. This makes it possible to override the default choice of storing all files in a temporary directory and unlinking them as soon as they have been opened.

Read multipart/* until last part. Arguments, all optional: fp : file pointer; default: sys.stdin.buffer (not used when the request method is GET) Can be : 1. a TextIOWrapper object 2. an object whose read() and readline() methods return bytes headers : header dictionary-like object; default: taken from environ as per CGI spec outerboundary : terminating multipart boundary (for internal use only) environ : environment dictionary; default: os.environ keep_blank_values: flag indicating whether blank values in percent-encoded forms should be treated as blank strings. A true value indicates that blanks should be retained as blank strings. The default false value indicates that blank values are to be ignored and treated as if they were not included. strict_parsing: flag indicating what to do with parsing errors. If false (the default), errors are silently ignored. If true, errors raise a ValueError exception. limit : used internally to read parts of multipart/form-data forms, to exit from the reading loop when reached. It is the difference between the form content-length and the number of bytes already read encoding, errors : the encoding and error handler used to decode the binary stream to strings. Must be the same as the charset defined for the page sending the form (content-type : meta http-equiv or header) max_num_fields: int.

The file will be used as follows: - data is written to it - seek(0) - data is read from it The file is opened in binary mode for files, in text mode for other fields This version opens a temporary file for reading and writing, and immediately deletes (unlinks) it. The trick (on Unix!) is that the file can still be used, but it can't be opened by another process, and it will automatically be deleted when it is closed or when the current process terminates. If you want a more permanent file, you derive a class which overrides this method. If you want a visible temporary file that is nevertheless automatically deleted when the script terminates, try defining a __del__ method in a derived class which unlinks the temporary files you have created. zwb+zw+r% )r* �newlineN)r� �tempfileZ TemporaryFiler* )rq r" r" r# r� } s zFieldStorage.make_file)N)Ni )!rt ru rv rw �osrA rr r� r� r� rs r� r� r� r� r� r� r� r� r� r� r� r� r� r� r� r� r� r� r� r� r� r� r" r" r" r# r l s@ * " D 1c C s� t d� t � tjt_yNt� }t� t� t|� t| � t � dd� }|fdd�}t d� |� W n t � Y nX t d� da y&t� }t� t� t|� t| � W n t � Y nX d S ) z�Robust test CGI script, usable as main program.

A configuration file consists of sections, lead by a "[section]" header, and followed by "name: value" entries, with continuations and such in the style of RFC 822. Intrinsic defaults can be specified by passing them into the ConfigParser constructor as a dictionary. class: ConfigParser -- responsible for parsing a list of configuration files, and managing the parsed database. methods: __init__(defaults=None, dict_type=_default_dict, allow_no_value=False, delimiters=('=', ':'), comment_prefixes=('#', ';'), inline_comment_prefixes=None, strict=True, empty_lines_in_values=True, default_section='DEFAULT', interpolation=<unset>, converters=<unset>): Create the parser. When `defaults' is given, it is initialized into the dictionary or intrinsic defaults. The keys must be strings, the values must be appropriate for %()s string interpolation. When `dict_type' is given, it will be used to create the dictionary objects for the list of sections, for the options within a section, and for the default values. When `delimiters' is given, it will be used as the set of substrings that divide keys from values. When `comment_prefixes' is given, it will be used as the set of substrings that prefix comments in empty lines. Comments can be indented. When `inline_comment_prefixes' is given, it will be used as the set of substrings that prefix comments in non-empty lines. When `strict` is True, the parser won't allow for any section or option duplicates while reading from a single source (file, string or dictionary). Default is True. When `empty_lines_in_values' is False (default: True), each empty line marks the end of an option. Otherwise, internal empty lines of a multiline option are kept as part of the value. When `allow_no_value' is True (default: False), options without values are accepted; the value presented for these is None. When `default_section' is given, the name of the special section is named accordingly. By default it is called ``"DEFAULT"`` but this can be customized to point to any other valid section name. Its current value can be retrieved using the ``parser_instance.default_section`` attribute and may be modified at runtime. When `interpolation` is given, it should be an Interpolation subclass instance. It will be used as the handler for option value pre-processing when using getters. RawConfigParser object s don't do any sort of interpolation, whereas ConfigParser uses an instance of BasicInterpolation. The library also provides a ``zc.buildbot`` inspired ExtendedInterpolation implementation. When `converters` is given, it should be a dictionary where each key represents the name of a type converter and each value is a callable implementing the conversion from string to the desired datatype. Every converter gets its corresponding get*() method on the parser object and section proxies. sections() Return all the configuration section names, sans DEFAULT. has_section(section) Return whether the given section exists. has_option(section, option) Return whether the given option exists in the given section. options(section) Return list of configuration options for the named section. read(filenames, encoding=None) Read and parse the iterable of named configuration files, given by name. A single filename is also allowed. Non-existing files are ignored. Return list of successfully read files. read_file(f, filename=None) Read and parse one configuration file, given as a file object. The filename defaults to f.name; it is only used in error messages (if f has no `name' attribute, the string `<???>' is used). read_string(string) Read configuration from a given string. read_dict(dictionary) Read configuration from a dictionary. Keys are section names, values are dictionaries with keys and values that should be present in the section. If the used dictionary type preserves order, sections and their keys will be added in order. Values are automatically converted to strings. get(section, option, raw=False, vars=None, fallback=_UNSET) Return a string value for the named option. All % interpolations are expanded in the return values, based on the defaults passed into the constructor and the DEFAULT section. Additional substitutions may be provided using the `vars' argument, which must be a dictionary whose contents override any pre-existing defaults. If `option' is a key in `vars', the value from `vars' is used. getint(section, options, raw=False, vars=None, fallback=_UNSET) Like get(), but convert value to an integer. getfloat(section, options, raw=False, vars=None, fallback=_UNSET) Like get(), but convert value to a float. getboolean(section, options, raw=False, vars=None, fallback=_UNSET) Like get(), but convert value to a boolean (currently case insensitively defined as 0, false, no, off for False, and 1, true, yes, on for True). Returns False or True. items(section=_UNSET, raw=False, vars=None) If section is given, return a list of tuples with (name, value) for each option in the section. Otherwise, return a list of tuples with (section_name, section_proxy) for each section, including DEFAULTSECT. remove_section(section) Remove the given file section and all its options. remove_option(section, option) Remove the given option from the given section. set(section, option, value) Set the given option. write(fp, space_around_delimiters=True) Write the configuration state in .ini format. If `space_around_delimiters' is True (the default), delimiters between keys and values are surrounded by spaces. � )�MutableMapping)� OrderedDict�ChainMapN�NoSectionError�DuplicateOptionError�DuplicateSectionError� NoOptionError�InterpolationError�InterpolationDepthError� InterpolationMissingOptionError�InterpolationSyntaxError� ParsingError�MissingSectionHeaderError� ConfigParser�SafeConfigParser�RawConfigParser� Interpolation�BasicInterpolation�ExtendedInterpolation�LegacyInterpolation� SectionProxy�ConverterMapping� DEFAULTSECT�MAX_INTERPOLATION_DEPTHZDEFAULT� c @ s& e Zd ZdZddd�Zdd� ZeZdS ) �Errorz'Base class for ConfigParser exceptions.� c C s || _ tj| |� d S )N)�message� Exception�__init__)�self�msg� r" �$/usr/lib64/python3.6/configparser.pyr � s zError.__init__c C s | j S )N)r )r r" r" r# �__repr__� s zError.__repr__N)r )�__name__� __module__� __qualname__�__doc__r r$ �__str__r" r" r" r# r � s r c @ s e Zd ZdZdd� ZdS )r z2Raised when no section matches a requested option.c C s$ t j| d|f � || _|f| _d S )NzNo section: %r)r r �section�args)r r* r" r" r# r � s zNoSectionError.__init__N)r% r& r' r( r r" r" r" r# r � s c @ s e Zd ZdZddd�ZdS )r a Raised when a section is repeated in an input source.

Interpolation as implemented in the classic ConfigParser. The option values can contain format strings which refer to other values in the same section, or values in the special default section. For example: something: %(dir)s/whatever would resolve the "%(dir)s" to the value of dir. All reference expansions are done late, on demand. If a user needs to use a bare % in a configuration file, she can escape it by writing %%.

However, due to malformed data, it may not. We don't want an all or nothing approach, so we allow for small variations in this number. 1) build a table of the frequency of each character on every line. 2) build a table of frequencies of this frequency (meta-frequency?), e.g. 'x occurred 5 times in 10 rows, 6 times in 1000 rows, 7 times in 2 rows' 3) use the mode of the meta-frequency to determine the /expected/ frequency for that character 4) find out how often the character actually meets that goal 5) the character that best meets its goal is the delimiter For performance reasons, the data is evaluated in chunks, so it can try and evaluate the smallest portion of the data possible, evaluating additional chunks as necessary.

In simplest use, end each module M to be tested with: def _test(): import doctest doctest.testmod() if __name__ == "__main__": _test() Then running the module as a script will cause the examples in the docstrings to get executed and verified: python M.py This won't display anything unless an example fails, in which case the failing example(s) and the cause(s) of the failure(s) are printed to stdout (why not stderr? because stderr is a lame hack <0.2 wink>), and the final line of output is "Test failed.". Run it with the -v switch instead: python M.py -v and a detailed report of all examples tried is printed to stdout, along with assorted summaries at the end. You can force verbose mode by passing "verbose=True" to testmod, or prohibit it by passing "verbose=False". In either of those cases, sys.argv is not examined by testmod. There are a variety of other ways to run doctests, including integration with the unittest framework, and support for running non-Python text files containing doctests. There are also many ways to override parts of doctest's default behaviors.

The constructor adds a newline if needed. - want: The expected output from running the source code (either from stdout, or a traceback in case of exception). `want` ends with a newline unless it's empty, in which case it's an empty string. The constructor adds a newline if needed. - exc_msg: The exception message generated by the example, if the example is expected to generate an exception; or `None` if it is not expected to generate an exception. This exception message is compared against the return value of `traceback.format_exception_only()`. `exc_msg` ends with a newline unless it's `None`. The constructor adds a newline if needed. - lineno: The line number within the DocTest string containing this Example where the Example begins. This line number is zero-based, with respect to the beginning of the DocTest. - indent: The example's indentation in the DocTest string. I.e., the number of space characters that precede the example's first prompt. - options: A dictionary mapping from option flags to True or False, which is used to override default options for this example. Any option flags not contained in this dictionary are left at their default value (as specified by the DocTestRunner's optionflags). By default, no options are set.

The object's module is used: - As a default namespace, if `globs` is not specified. - To prevent the DocTestFinder from extracting DocTests from objects that are imported from other modules. - To find the name of the file containing the object. - To help find the line number of the object within its file. Contained objects whose module does not match `module` are ignored. If `module` is False, no attempt to find the module will be made. This is obscure, of use mostly in tests: if `module` is False, or is None but cannot be found automatically, then all objects are considered to belong to the (non-existent) module, so all contained objects will (recursively) be searched for doctests. The globals for each DocTest is formed by combining `globs` and `extraglobs` (bindings in `extraglobs` override bindings in `globs`). A new copy of the globals dictionary is created for each DocTest. If `globs` is not specified, then it defaults to the module's `__dict__`, if specified, or {} otherwise. If `extraglobs` is not specified, then it defaults to {}.

The `run` method is used to process a single DocTest case. It returns a tuple `(f, t)`, where `t` is the number of test cases tried, and `f` is the number of test cases that failed. >>> tests = DocTestFinder().find(_TestClass) >>> runner = DocTestRunner(verbose=False) >>> tests.sort(key = lambda test: test.name) >>> for test in tests: ... print(test.name, '->', runner.run(test)) _TestClass -> TestResults(failed=0, attempted=2) _TestClass.__init__ -> TestResults(failed=0, attempted=2) _TestClass.get -> TestResults(failed=0, attempted=2) _TestClass.square -> TestResults(failed=0, attempted=1) The `summarize` method prints a summary of all the test cases that have been run by the runner, and returns an aggregated `(f, t)` tuple: >>> runner.summarize(verbose=1) 4 items passed all tests: 2 tests in _TestClass 2 tests in _TestClass.__init__ 2 tests in _TestClass.get 1 tests in _TestClass.square 7 tests in 4 items. 7 passed and 0 failed. Test passed. TestResults(failed=0, attempted=7) The aggregated number of tried examples and failed examples is also available via the `tries` and `failures` attributes: >>> runner.tries 7 >>> runner.failures 0 The comparison between expected outputs and actual outputs is done by an `OutputChecker`. This comparison may be customized with a number of option flags; see the documentation for `testmod` for more information. If the option flags are insufficient, then the comparison may also be customized by passing a subclass of `OutputChecker` to the constructor. The test runner's display output can be controlled in two ways. First, an output function (`out) can be passed to `TestRunner.run`; this function will be called with strings that should be displayed. It defaults to `sys.stdout.write`. If capturing the output is not sufficient, then the display output can be also customized by subclassing DocTestRunner, and overriding the methods `report_start`, `report_success`, `report_unexpected_exception`, and `report_failure`. r4 �F Nr" c C sN |pt � | _|dkr dtjk}|| _|| _|| _d| _d| _i | _ t � | _ dS )ac Create a new test runner.

By default, this path is relative to the calling module's directory; but if the "package" argument is specified, then it is relative to that package. To ensure os-independence, "filename" should use "/" characters to separate path segments, and should not be an absolute path (i.e., it may not begin with "/"). - If "module_relative" is False, then "filename" specifies an os-specific path. The path may be absolute or relative (to the current working directory). Optional keyword arg "name" gives the name of the test; by default use the file's basename. Optional keyword argument "package" is a Python package or the name of a Python package whose directory should be used as the base directory for a module relative filename. If no package is specified, then the calling module's directory is used as the base directory for module relative filenames. It is an error to specify "package" if "module_relative" is False. Optional keyword arg "globs" gives a dict to be used as the globals when executing examples; by default, use {}. A copy of this dict is actually used for each docstring, so that each docstring's examples start with a clean slate. Optional keyword arg "extraglobs" gives a dictionary that should be merged into the globals that are used to execute examples. By default, no extra globals are used.

If not specified, then it will default to the set of future-import flags that apply to `globs`. Optional keyword arg `optionflags` specifies options for the testing and output.

The test code is run in such a way that errors are not caught. This way a caller can catch the errors and initiate post-mortem debugging. The DocTestCase provides a debug method that raises UnexpectedException errors if there is an unexpected exception: >>> test = DocTestParser().get_doctest('>>> raise KeyError\n42', ... {}, 'foo', 'foo.py', 0) >>> case = DocTestCase(test) >>> try: ... case.debug() ... except UnexpectedException as f: ... failure = f The UnexpectedException contains the test, the example, and the original exception: >>> failure.test is test True >>> failure.example.want '42\n' >>> exc_info = failure.exc_info >>> raise exc_info[1] # Already has the traceback Traceback (most recent call last): ... KeyError If the output doesn't match, then a DocTestFailure is raised: >>> test = DocTestParser().get_doctest(''' ... >>> x = 1 ... >>> x ... 2 ... ''', {}, 'foo', 'foo.py', 0) >>> case = DocTestCase(test) >>> try: ... case.debug() ... except DocTestFailure as f: ... failure = f DocTestFailure objects provide access to the test: >>> failure.test is test True As well as to the example: >>> failure.example.want '2\n' and the actual output: >>> failure.got '1\n' F)r r r� )r?

This converts each documentation string in a module that contains doctest tests to a unittest test case. If any of the tests in a doc string fail, then the test case fails. An exception is raised showing the name of the file containing the test and a (sometimes approximate) line number. The `module` argument provides the module to be tested. The argument can be either a module or a module name. If no argument is given, the calling module is used. A number of options may be provided as keyword arguments: setUp A set-up function. This is called before running the tests in each file. The setUp function will be passed a DocTest object. The setUp function can access the test globals as the globs attribute of the test passed. tearDown A tear-down function. This is called after running the tests in each file. The tearDown function will be passed a DocTest object. The tearDown function can access the test globals as the globs attribute of the test passed. globs A dictionary containing initial global variables for the tests. optionflags A set of doctest option flags expressed as an integer.

The path to each doctest file is given as a string; the interpretation of that string depends on the keyword argument "module_relative". A number of options may be provided as keyword arguments: module_relative If "module_relative" is True, then the given file paths are interpreted as os-independent module-relative paths. By default, these paths are relative to the calling module's directory; but if the "package" argument is specified, then they are relative to that package. To ensure os-independence, "filename" should use "/" characters to separate path segments, and may not be an absolute path (i.e., it may not begin with "/"). If "module_relative" is False, then the given file paths are interpreted as os-specific paths. These paths may be absolute or relative (to the current working directory). package A Python package or the name of a Python package whose directory should be used as the base directory for module relative paths. If "package" is not specified, then the calling module's directory is used as the base directory for module relative filenames. It is an error to specify "package" if "module_relative" is False. setUp A set-up function. This is called before running the tests in each file. The setUp function will be passed a DocTest object. The setUp function can access the test globals as the globs attribute of the test passed. tearDown A tear-down function. This is called after running the tests in each file. The tearDown function will be passed a DocTest object. The tearDown function can access the test globals as the globs attribute of the test passed. globs A dictionary containing initial global variables for the tests. optionflags A set of doctest option flags expressed as an integer. parser A DocTestParser (or subclass) that should be used to extract tests from the files. encoding An encoding that will be used to convert the files to unicode. rS TrR )rn r. rC rr rv )�paths�kwrs r� r+ r+ r, r � s 8 c C s� g }x�t � j| �D ]x}t|t�rj|j|jdd � � |j}|r�|jd� |dd� |jd�dd � D �7 }q|dd� |jd�dd � D �7 }qW x |r�|d dkr�|j� q�W x |r�|d dkr�|jd � q�W dj |�d S )aw Extract script from text with examples.

The optional *protocol* argument tells the pickler to use the given protocol; supported protocols are 0, 1, 2, 3 and 4. The default protocol is 3; a backward-incompatible protocol designed for Python 3. Specifying a negative protocol version selects the highest protocol version supported. The higher the protocol used, the more recent the version of Python needed to read the pickle produced. The *file* argument must have a write() method that accepts a single bytes argument. It can thus be a file object opened for binary writing, an io.BytesIO instance, or any other custom object that meets this interface. If *fix_imports* is True and *protocol* is less than 3, pickle will try to map the new Python 3 names to the old module names used in Python 2, so that the pickle data stream is readable with Python 2.

reading a pickle data stream. The protocol version of the pickle is detected automatically, so no proto argument is needed. The argument *file* must have two methods, a read() method that takes an integer argument, and a readline() method that requires no arguments. Both methods should return bytes. Thus *file* can be a binary file object opened for reading, an io.BytesIO object, or any other custom object that meets this interface. The file-like object must have two methods, a read() method that takes an integer argument, and a readline() method that requires no arguments. Both methods should return bytes. Thus file-like object can be a binary file object opened for reading, a BytesIO object, or any other custom object that meets this interface. Optional keyword arguments are *fix_imports*, *encoding* and *errors*, which are used to control compatibility support for pickle stream generated by Python 2. If *fix_imports* is True, pickle will try to map the old Python 2 names to the new names used in Python 3. The *encoding* and *errors* tell pickle how to decode 8-bit string instances pickled by Python 2; these default to 'ASCII' and 'strict', respectively. *encoding* can be 'bytes' to read theses 8-bit string instances as bytes objects. r N) r� �_file_readliner� � _file_readr� rL rM r� r� )r r� r� rL rM r r r r � s z_Unpickler.__init__c C s� t | d�s td| jjf ��t| j| j�| _| jj| _| jj | _ g | _ g | _ | j j | _ d| _ | j}| j}y8x2|d�}|s|t�t|t�s�t�||d | � qlW W n" tk r� } z|jS d}~X nX dS )z�Read a pickled object representation from the open file.

Note that we don't define __hash__: not all sets are hashable. But if you define a hashable set type, its __hash__ should call this function. This must be compatible __eq__. All sets ought to compare equal if they contain the same elements, regardless of how they are implemented, and regardless of the order of the elements; so there's not much freedom for __eq__ or __hash__. We match the algorithm used by the built-in frozenset type. � r iM��r� i�M[l �4~2 i� i��6i��8#���)�sys�maxsizerT �hash)r. �MAX�MASK�n�hrN �hxr r r! �_hash s z Set._hashN)r2 r3 r4 �__doc__r5 rW rX rZ rY r[ r6 r] r` �__rand__ra re �__ror__rf rg rh �__rxor__rt r r r r! r � s$ c @ sd e Zd ZdZf Zedd� �Zedd� �Zdd� Zdd � Z d d � Z d d � Z dd� Z dd� Z dd� ZdS )r a� A mutable set is a finite, iterable container.

SMTP Objects: SMTP objects have the following attributes: helo_resp This is the message given by the server in response to the most recent HELO command. ehlo_resp This is the message given by the server in response to the most recent EHLO command. This is usually multiline. does_esmtp This is a True value _after you do an EHLO command_, if the server supports ESMTP. esmtp_features This is a dictionary, which, if the server supports ESMTP, will _after you do an EHLO command_, contain the names of the SMTP service extensions this server supports, and their parameters (if any). Note, all extension names are mapped to lower case in the dictionary. See each method's docstrings for details. In general, there is a method of the same name to perform each SMTP command. There is also a method called 'sendmail' that will do an entire mail transaction. r N�ehlor c C s� || _ || _i | _d| _|| _|rL| j||�\}}|dkrL| j� t||��|dk r\|| _nPt j � }d|krt|| _n8d} yt j t j � �} W n t j k r� Y nX d| | _dS )a Initialize a new instance. If specified, `host' is the name of the remote host to which to connect. If specified, `port' specifies the port to which to connect. By default, smtplib.SMTP_PORT is used. If a host is specified the connect method is called, and if it returns anything other than a success code an SMTPConnectError is raised. If specified, `local_hostname` is used as the FQDN of the local host in the HELO/EHLO command. Otherwise, the local hostname is found using socket.getfqdn(). The `source_address` parameter takes a 2-tuple (host, port) for the socket to bind to as its source address before connecting. If the host is '' and port is 0, the OS default behavior will be used. �ascii�� N�.z 127.0.0.1z[%s])�_host�timeout�esmtp_features�command_encoding�source_address�connect�closer �local_hostname�socketZgetfqdnZ gethostbynameZ gethostnameZgaierror) r �host�portr< r6 r9 r r Zfqdnr) r r r r � s* z SMTP.__init__c C s | S )Nr )r r r r � __enter__ s zSMTP.__enter__c G sN z>y$| j d�\}}|dkr$t||��W n tk r: Y nX W d | j� X d S )NZQUIT�� )�docmdr r r; )r r r �messager r r �__exit__ s z SMTP.__exit__c C s || _ dS )z�Set the debug output level.

The arguments are: - from_addr : The address sending this mail. - to_addrs : A list of addresses to send this mail to. A bare string will be treated as a list with 1 address. - msg : The message to send. - mail_options : List of ESMTP options (such as 8bitmime) for the mail command. - rcpt_options : List of ESMTP options (such as DSN commands) for all the rcpt commands. msg may be a string containing characters in the ASCII range, or a byte string. A string is encoded to bytes using the ascii codec, and lone \r and \n characters are converted to \r\n characters. If there has been no previous EHLO or HELO command this session, this method tries ESMTP EHLO first. If the server does ESMTP, message size and each of the specified options will be passed to it. If EHLO fails, HELO will be tried and ESMTP options suppressed. This method will return normally if the mail is accepted for at least one recipient. It returns a dictionary, with one entry for each recipient that was refused. Each entry contains a tuple of the SMTP error code and the accompanying error message sent by the server. This method may raise the following exceptions: SMTPHeloError The server didn't reply properly to the helo greeting. SMTPRecipientsRefused The server rejected ALL recipients (no mail was sent). SMTPSenderRefused The server didn't accept the from_addr. SMTPDataError The server replied with an unexpected error code (other than a refusal of a recipient). SMTPNotSupportedError The mail_options parameter includes 'SMTPUTF8' but the SMTPUTF8 extension is not supported by the server. Note: the connection will be open even after an exception is raised.

This is a test ''' >>> s.sendmail("me@my.org",tolist,msg) { "three@three.org" : ( 550 ,"User unknown" ) } >>> s.quit() In the above example, the message was accepted for delivery to three of the four addresses, and one was rejected, with the error code 550. If all addresses are accepted, then the method will return an empty dictionary. r2 �sizezsize=%drw i� � )r� r] r^ r0 r_ r~ r� rn rm r� r; r� r r� r r. r ) r � from_addr�to_addrsr � mail_options� rcpt_optionsZ esmtp_optsZoptionr rp Zsenderrsr� r r r �sendmail sF @ z SMTP.sendmailc C s� | j � |jd�}|dkr d}nt|�dkr2d}ntd��|dkr||d |krZ||d n ||d }tjj|g�d d }|dkr�d d � ||d ||d ||d fD �}dd � tjj|�D �}tj|�} | d = | d= d} ydj|f|��j d� W n. t k �r( | j d��s t d��d} Y nX t j� �R} | �r^tjj| |jjdd�d�} |d �}n tjj| �} | j| dd� | j� } W dQ R X | j||| ||�S ) a~ Converts message to a bytestring and passes it to sendmail. The arguments are as for sendmail, except that msg is an email.message.Message object. If from_addr is None or to_addrs is None, these arguments are taken from the headers of the Message as described in RFC 2822 (a ValueError is raised if there is more than one set of 'Resent-' headers). Regardless of the values of from_addr and to_addr, any Bcc field (or Resent-Bcc field, when the Message is a resent) of the Message object won't be transmitted. The Message object is then serialized using email.generator.BytesGenerator and sendmail is called to transmit the message. If the sender or any of the recipient addresses contain non-ASCII and the server advertises the SMTPUTF8 capability, the policy is cloned with utf8 set to True for the serialization, and SMTPUTF8 and BODY=8BITMIME are asserted on the send. If the server does not support SMTPUTF8, an SMTPNotSupported error is raised. Otherwise the generator is called without modifying the policy. z Resent-DateNr rG zResent-z0message has more than one 'Resent-' header blockZSender�Fromr c S s g | ]}|d k r|�qS )Nr )r� �fr r r r� � s z%SMTP.send_message.<locals>.<listcomp>�ToZBccZCcc S s g | ] }|d �qS )rG r )r� �ar r r r� � s z Resent-BccFr2 r� z�One or more source or delivery addresses require internationalized email support, but the server does not advertise the required SMTPUTF8 capabilityT)�utf8)�policy�SMTPUTF8� BODY=8BITMIMEz )�linesep)r� r� )r� Zget_allrm rU r" r# Z getaddresses�copyro r_ �UnicodeEncodeErrorr� r �io�BytesIO� generatorZBytesGeneratorr� ZcloneZflatten�getvaluer� )r r r� r� r� r� ZresentZ header_prefixZ addr_fieldsZmsg_copyZ internationalZbytesmsg�gZflatmsgr r r � send_message| sJ zSMTP.send_messagec C s< z | j }d| _ |r|j� W d| j}d| _|r6|j� X dS )z(Close the connection to the SMTP server.N)rH r; rX )r rH rX r r r r; � s z SMTP.closec C s. | j d�}d | _| _i | _d| _| j� |S )zTerminate the SMTP session.�quitNF)rB r} ru r7 r~ r; )r �resr r r r� � s z SMTP.quit)rP r N)r )r )r )r )r )N)N)N)NNN)1r r r r rE rH ru r| r} r~ � SMTP_PORTrW r= �_GLOBAL_DEFAULT_TIMEOUTr r@ rD rF rM rO r: ra rc rY rB rt r1 r� r� r� r� r� r� r� r. r� r� r� r� ry r� r� r� r� r� r� r� r; r� r r r r r � s^ - " 1 3 ' B 8 gL c @ s8 e Zd ZdZeZdddddejddfdd�Zdd� Z dS ) �SMTP_SSLa� This is a subclass derived from SMTP that connects over an SSL encrypted socket (to use this class you need a socket module that was compiled with SSL support). If host is not specified, '' (the local host) is used. If port is omitted, the standard SMTP-over-SSL port (465) is used. local_hostname and source_address have the same meaning as they do in the SMTP class. keyfile and certfile are also optional - they can contain a PEM formatted private key and certificate chain file for the SSL connection. context also optional, can contain a SSLContext, and is an alternative to keyfile and certfile; If it is specified both keyfile and certfile must be None. r r Nc C s� |d k r|d k rt d��|d k r0|d k r0t d��|d k s@|d k rVdd l} | jdtd� || _|| _|d krxtj||d�}|| _t j | |||||� d S )Nz4context and keyfile arguments are mutually exclusivez5context and certfile arguments are mutually exclusiver zAkeyfile and certfile are deprecated, use a custom context insteadr� )r� r� ) rU r� r� r� r� r� r� r� r� r r ) r r> r? r< r� r� r6 r9 r� r� r r r r � s zSMTP_SSL.__init__c C sD | j dkr| jd||f� tj||f|| j�}| jj|| jd�}|S )Nr zconnect:)r� )rE rM r= rN r9 r� r� r5 )r r> r? r6 Z new_socketr r r rO s zSMTP_SSL._get_socket) r r r r � SMTP_SSL_PORTrW r= r� r rO r r r r r� � s r� i� c @ s0 e Zd ZdZdZdeddfdd�Zd d d �ZdS ) �LMTPa� LMTP - Local Mail Transfer Protocol The LMTP protocol, which is very similar to ESMTP, is heavily based on the standard SMTP client. It's common to use Unix sockets for LMTP, so our connect() method must support that as well as a regular host:port server. local_hostname and source_address have the same meaning as they do in the SMTP class. To specify a Unix socket, you must use an absolute path as the host, starting with a '/'. Authentication is supported, using the regular SMTP mechanism. When using a Unix socket, LMTP generally don't support or require any authentication, but your mileage might vary.Zlhlor Nc C s t j| ||||d� dS )zInitialize a new instance.)r< r9 N)r r )r r> r? r< r9 r r r r ) s z LMTP.__init__rP r c C s� |d dkr t j| |||d�S y(tjtjtj�| _d| _| jj|� W nB tk r� | jdkrl| j d|� | jr|| jj � d| _� Y nX | j � \}}| jdkr�| j d|� ||fS )z=Connect to the LMTP daemon, on either a Unix or a TCP socket.r �/)r9 Nz connect fail:zconnect:) r r: r= ZAF_UNIXZ SOCK_STREAMrX rH rV rE rM r; rY )r r> r? r9 r r r r r r: / s" z LMTP.connect)rP r N)r r r r r| � LMTP_PORTr r: r r r r r� s r� �__main__c C s( t jj| d � t jj� t jj� j� S )Nz: )rK �stdout�write�flush�stdinrk r% )�promptr r r r� I s r� r� r� �,zEnter message, end with ^D:r zMessage length is %drP rG )@r r= r� r+ Z email.utilsr" Z email.messageZemail.generatorr� r� r� rJ rK Zemail.base64mimer r� �__all__r� r� r- r� rl �compile�Ir� rV r r r r r r r r r r r r* r r/ r0 r� � ImportErrorr� r r� rn r� r� r r� Zfromaddrr� ZtoaddrsrI r r� rk rq rm ZserverrF r� r� r r r r �<module>! s� )0 / _dummy_thread.cpython-36.opt-2.pyc 0000644 00000005125 15246273046 0012767 0 ustar 00 3 \� � @ st d ddddddgZ dZeZi fd d�Zd d� Zd d� Zd d� Zddd�Zdd� Z G dd� de �Z da da dd� Zd S )�error�start_new_thread�exit� get_ident� allocate_lock�interrupt_main�LockType� � c C s� t |�t t� �krtd��t |�t t� �kr4td��day| ||� W n. tk rZ Y n dd l}|j� Y nX datr�dat �d S )Nz2nd arg must be a tuplez3rd arg must be a dictF� T) �type�tuple� TypeError�dict�_main� SystemExit� traceback� print_exc� _interrupt�KeyboardInterrupt)Zfunction�args�kwargsr � r �%/usr/lib64/python3.6/_dummy_thread.pyr s c C s t �d S )N)r r r r r r = s c C s dS )N� ���r r r r r r A s c C s t � S )N)r r r r r r J s Nc C s | d k rt d��dS )Nz'setting thread stack size not supportedr )r )�sizer r r � stack_sizeN s r c C s t � S )N)r r r r r � _set_sentinelT s r c @ sB e Zd Zdd� Zddd�ZeZdd� Zd d � Zd d � Zd d� Z dS )r c C s d| _ d S )NF)� locked_status)�selfr r r �__init__c s zLockType.__init__Nr c C sH |d ks |rd| _ dS | j s&d| _ dS |dkr@dd l}|j|� dS d S )NTr F)r �timeZsleep)r ZwaitflagZtimeoutr! r r r �acquiref s zLockType.acquirec C s | j � d S )N)�release)r �typ�val�tbr r r �__exit__� s zLockType.__exit__c C s | j s t�d| _ dS )NFT)r r )r r r r r# � s zLockType.releasec C s | j S )N)r )r r r r �locked� s zLockType.lockedc C s* d| j r dnd| jj| jjtt| ��f S )Nz<%s %s.%s object at %s>r( Zunlocked)r � __class__� __module__� __qualname__�hex�id)r r r r �__repr__� s zLockType.__repr__r )Nr ) �__name__r* r+ r r" � __enter__r' r# r( r. r r r r r X s FTc C s t r t�ndad S )NT)r r r r r r r r � s l )N)�__all__� TIMEOUT_MAX� RuntimeErrorr r r r r r r �objectr r r r r r r r �<module> s @ glob.cpython-36.pyc 0000644 00000010245 15246273046 0010130 0 ustar 00 3 \ � @ s� d Z ddlZddlZddlZdddgZdd�dd�Zdd�d d�Zd d � Zd d � Zdd� Z dd� Z dd� Z dd� Z dd� Z dd� Zejd�Zejd�Zd d � Zd d � Zd d!� Zd"d� ZdS )#zFilename globbing utility.� N�glob�iglob�escapeF)� recursivec C s t t| |d��S )ay Return a list of paths matching a pathname pattern.

At the Python interactive prompt, calling help(thing) on a Python object documents the object, and calling help() starts up an interactive help session. Or, at the shell command line outside of Python: Run "pydoc <name>" to show documentation on something. <name> may be the name of a function, module, package, or a dotted reference to a class or function within a module or module in a package. If the argument contains a path segment delimiter (e.g. slash on Unix, backslash on Windows) it is treated as the path to a Python source file. Run "pydoc -k <keyword>" to search for a keyword in the synopsis lines of all available modules. Run "pydoc -p <port>" to start an HTTP server on the given port on the local machine. Port number 0 can be used to get an arbitrary unused port. Run "pydoc -b" to start an HTTP server on an arbitrary unused port and open a Web browser to interactively browse documentation. The -p option can be used with the -b option to explicitly specify the server port. Run "pydoc -w <name>" to write out the HTML documentation for a module to a file named "<name>.html". Module docs for core modules are assumed to be in https://docs.python.org/X.Y/library/ This can be overridden by setting the PYTHONDOCS environment variable to a different URL or to a local directory containing the Library Reference Manual pages. �helpzKa-Ping Yee <ping@lfw.org>z26 February 2001z�Guido van Rossum, for an excellent programming language.

If the optional 'forceload' argument is 1, we reload the module from disk (unless it's a dynamic extension).c s g | ]}|j � d �r|�qS )r )ra )rk �m)r r r � <listcomp>Q s z safeimport.<locals>.<listcomp>Nr r )r r� �builtin_module_names� __import__r� r� rV � SyntaxErrorr� � issubclass� ImportErrorr( r r< �AttributeError) r � forceloadr� ZsubsrG r� r� rH r� �info�partr )r r � safeimport= s. r� c @ s| e Zd Zejjddejdd� �Zd dd�Z ddd�Z e Z Z Z Z ZZejjejd d ejdd� �fd d �ZdS )�Doc� PYTHONDOCSz%https://docs.python.org/%d.%d/libraryNr c G s� ||f| }t j|�r | j|� S t j|�r4| j|� S y@t j|�rJ| j|� S t j|�r^| j|� S t j|�rr| j |� S W n t k r� Y nX t |t �r�| j |� S | j|� S )z%Generate documentation for an object.)r �isgetsetdescriptor�docdata�ismemberdescriptorr* � docmoduler+ �docclassr, � docroutiner� � isinstance�property� docproperty�docother)r> r r( �argsr r r �documents s" z Doc.documentc G s* d|odt |� t|�jf }t|��dS )z+Raise an exception for unimplemented types.z.don't know how to document object%s of type %s� N)�repr�typer% rt )r> r r( r� �messager r r �fail� s zDoc.fail�libz python%d.%dc C s� yt j|�}W n tk r& d}Y nX tjjd| j�}tjj|�}t |t t��r�|j dks||j |�r�|j tjj |d �� r�|j dkr�|j d�r�d|jd�|j j� f }q�tjj ||j j� d �}nd}|S )z*Return the location of module docs or Nonez (built-in)r� �errno� exceptions�gc�imp�marshal�posix�signalr �_thread� zipimportz site-packages� xml.etree�test.pydoc_mod�http://�https://z%s/%s�/z.htmlN) r� r� r� r� r� r� r� r r� r� )r� r� )r� r� )r � getabsfilert r �environro r� r r r� r� r% ra r!

Start an HTML/text server thread, so HTML or text documents can be browsed dynamically and interactively with a Web browser. Example use: >>> import time >>> import pydoc Define a URL handler. To determine what the client is asking for, check the URL and content_type. Then get or generate some text or HTML code and return it. >>> def my_url_handler(url, content_type): ... text = 'the URL sent was: (%s, %s)' % (url, content_type) ... return text Start server thread on port 0. If you use port 0, the server will pick a random port number. You can then use serverthread.port to get the port number. >>> port = 0 >>> serverthread = pydoc._start_server(my_url_handler, port) Check that the server is really started. If it is, open browser and get first page. Use serverthread.url as the starting page. >>> if serverthread.serving: ... import webbrowser The next two lines are commented out so a browser doesn't open if doctest is run on this module. #... webbrowser.open(serverthread.url) #True Let the server do its thing. We just need to monitor its status. Use time.sleep so the loop doesn't hog the CPU. >>> starttime = time.time() >>> timeout = 1 #seconds This is a short timeout for testing purposes. >>> while serverthread.serving: ... time.sleep(.01) ... if serverthread.serving and time.time() - starttime > timeout: ... serverthread.stop() ... break Print any errors that may have occurred. >>> print(serverthread.error) None r Nc @ s e Zd Zdd� Zdd� ZdS )z!_start_server.<locals>.DocHandlerc S sX | j jd�rd}nd}| jd� | jdd| � | j� | jj| j| j |�jd�� dS ) z�Process a request from an HTML browser.

This module encapsulates the interface provided by the internal special attributes (co_*, im_*, tb_*, etc.) in a friendlier fashion. It also provides some help for examining source code and class layout. Here are some of the useful functions provided by this module: ismodule(), isclass(), ismethod(), isfunction(), isgeneratorfunction(), isgenerator(), istraceback(), isframe(), iscode(), isbuiltin(), isroutine() - check object types getmembers() - get members of an object that satisfy a given condition getfile(), getsourcefile(), getsource() - find an object's source code getdoc(), getcomments() - get documentation on an object getmodule() - determine the module that an object came from getclasstree() - arrange classes so as to represent their hierarchy getargvalues(), getcallargs() - get info about function arguments getfullargspec() - same, with support for Python 3 features formatargspec(), formatargvalues() - format an argument spec getouterframes(), getinnerframes() - get info about frames currentframe() - get the current stack frame stack(), trace() - get info about frames on the stack or in a traceback signature() - get a Signature object for the callable �Ka-Ping Yee <ping@lfw.org>�'Yury Selivanov <yselivanov@sprymix.com>� N)� attrgetter)� namedtuple� OrderedDictZCO_� � c C s t | tj�S )z�Return true if the object is a module.

A Signature object has the following public attributes and methods: * parameters : OrderedDict An ordered mapping of parameters' names to the corresponding Parameter objects (keyword-only arguments are in the same order as listed in `code.co_varnames`). * return_annotation : object The annotation for the return type of the function if specified. If the function has no annotation for its return type, this attribute is set to `Signature.empty`. * bind(*args, **kwargs) -> BoundArguments Creates a mapping from positional and keyword arguments to parameters. * bind_partial(*args, **kwargs) -> BoundArguments Creates a partial mapping from positional and keyword arguments to parameters (simulating 'functools.partial' behavior.) �_return_annotation� _parametersNT)r$ r� c C s� |dkrt � }n�|r�t � }t}d}x�t|�D ]�\}}|j} |j} | |k rjd} | jt|�t| ��} t| ��n| |krzd}| }| ttfkr�|j t kr�|r�d} t| ��nd}| |kr�dj| �} t| ��||| < q,W nt dd� |D ��}t j |�| _ || _dS ) z�Constructs Signature from the given list of Parameter objects and 'return_annotation'.

Typical use is: import fileinput for line in fileinput.input(): process(line) This iterates over the lines of all files listed in sys.argv[1:], defaulting to sys.stdin if the list is empty. If a filename is '-' it is also replaced by sys.stdin. To specify an alternative list of filenames, pass it as the argument to input(). A single file name is also allowed. Functions filename(), lineno() return the filename and cumulative line number of the line that has just been read; filelineno() returns its line number in the current file; isfirstline() returns true iff the line just read is the first line of its file; isstdin() returns true iff the line was read from sys.stdin. Function nextfile() closes the current file so that the next iteration will read the first line from the next file (if any); lines not read from the file will not count towards the cumulative line count; the filename is not changed until after the first line of the next file has been read. Function close() closes the sequence. Before any lines have been read, filename() returns None and both line numbers are zero; nextfile() has no effect. After all lines have been read, filename() and the line number functions return the values pertaining to the last line read; nextfile() has no effect. All files are opened in text mode by default, you can override this by setting the mode parameter to input() or FileInput.__init__(). If an I/O error occurs during opening or reading a file, the OSError exception is raised. If sys.stdin is used more than once, the second and further use will return no lines, except perhaps for interactive use, or if it has been explicitly reset (e.g. using sys.stdin.seek(0)). Empty files are opened and immediately closed; the only time their presence in the list of filenames is noticeable at all is when the last file opened is empty. It is possible that the last line of a file doesn't end in a newline character; otherwise lines are returned including the trailing newline. Class FileInput is the implementation; its methods filename(), lineno(), fileline(), isfirstline(), isstdin(), nextfile() and close() correspond to the functions in the module. In addition it has a readline() method which returns the next input line, and a __getitem__() method which implements the sequence behavior. The sequence must be accessed in strictly sequential order; sequence access and readline() cannot be mixed. Optional in-place filtering: if the keyword argument inplace=1 is passed to input() or to the FileInput constructor, the file is moved to a backup file and standard output is directed to the input file. This makes it possible to write a filter that rewrites its input file in place. If the keyword argument backup=".<some extension>" is also given, it specifies the extension for the backup file, and the backup file remains around; by default, the extension is ".bak" and it is deleted when the output file is closed. In-place filtering is disabled when standard input is read. XXX The current implementation does not work for MS-DOS 8+3 filesystems.

According to POSIX, a program which has not called setlocale(LC_ALL, "") runs using the portable 'C' locale. Calling setlocale(LC_ALL, "") lets it use the default locale as defined by the LANG variable. Since we don't want to interfere with the current locale setting we thus emulate the behavior in the way described above. To maintain compatibility with other platforms, not only the LANG variable is tested, but a list of variables given as envvars parameter. The first found to be defined will be used. envvars defaults to the search path used in GNU gettext; it must always contain the variable name 'LANG'. Except for the code 'C', the language code corresponds to RFC 1766. code and encoding can be None in case the values cannot be determined. r NZwin32r' Z0xr� r� r< ) �_localeZ_getdefaultlocale� ImportError�AttributeError�sys�platform�windows_localer~ rs �os�environr[ r� )Zenvvarsr� r� r� r� �lookupZvariabler� r r r r s$ c C s( t | �}| tkr d|kr td��t|�S )ap Returns the current setting for the given locale category as tuple (language code, encoding). category may be one of the LC_* value except LC_ALL.

This module helps scripts to parse the command line arguments in sys.argv. It supports the same conventions as the Unix getopt() function (including the special meanings of arguments of the form `-' and `--'). Long options similar to those supported by GNU software may be used as well via an optional third argument. This module provides two functions and an exception: getopt() -- Parse command line options gnu_getopt() -- Like getopt(), but allow option and non-option arguments to be intermixed. GetoptError -- exception (class) raised with 'opt' attribute, which is the option involved with the exception. � GetoptError�error�getopt� gnu_getopt� N)�gettextc C s | S )N� )�sr r � /usr/lib64/python3.6/getopt.py�_) s r c @ s& e Zd ZdZdZddd�Zdd� ZdS )r � c C s || _ || _tj| ||� d S )N)�msg�opt� Exception�__init__)�selfr r r r r r . s zGetoptError.__init__c C s | j S )N)r )r r r r �__str__3 s zGetoptError.__str__N)r )�__name__� __module__� __qualname__r r r r r r r r r + s c C s� g }t |�t d�kr |g}nt|�}x�| r�| d jd�r�| d dkr�| d dkr^| dd� } P | d jd�r�t|| d dd� || dd� �\}} q&t|| d dd� || dd� �\}} q&W || fS )a@ getopt(args, options[, long_options]) -> opts, args Parses command line options and parameter list. args is the argument list to be parsed, without the leading reference to the running program. Typically, this means "sys.argv[1:]". shortopts is the string of option letters that the script wants to recognize, with options that require an argument followed by a colon (i.e., the same format that Unix getopt() uses). If specified, longopts is a list of strings with the names of the long options which should be supported. The leading '--' characters should not be included in the option name. Options which require an argument should be followed by an equal sign ('='). The return value consists of two elements: the first is a list of (option, value) pairs; the second is the list of program arguments left after the option list was stripped (this is a trailing slice of the first argument). Each option-and-value pair returned has the option as its first element, prefixed with a hyphen (e.g., '-x'), and the option argument as its second element, or an empty string if the option has no argument. The options occur in the list in the same order in which they were found, thus allowing multiple occurrences.

Arguments are as for compile_command(). One several things can happen: 1) The input is incorrect; compile_command() raised an exception (SyntaxError or OverflowError). A syntax traceback will be printed by calling the showsyntaxerror() method. 2) The input is incomplete, and more input is required; compile_command() returned None. Nothing happens. 3) The input is complete; compile_command() returned a code object. The code is executed by calling self.runcode() (which also handles run-time exceptions, except for SystemExit). The return value is True in case 2, False in the other cases (unless an exception is raised). The return value can be used to decide whether to use sys.ps1 or sys.ps2 to prompt the next line.

The optional banner argument specifies the banner to print before the first interaction; by default it prints a banner similar to the one printed by the real Python interpreter, followed by the current class name in parentheses (so as not to confuse this with the real interpreter -- since it's so close!). The optional exitmsg argument specifies the exit message printed when exiting. Pass the empty string to suppress printing an exit message.

The line should not have a trailing newline; it may have internal newlines. The line is appended to a buffer and the interpreter's runsource() method is called with the concatenated contents of the buffer as source. If this indicates that the command was executed or invalid, the buffer is reset; otherwise, the command is incomplete, and the buffer is left as it was after the line was appended.

The 'record' argument specifies whether warnings should be captured by a custom implementation of warnings.showwarning() and be appended to a list returned by the context manager. Otherwise None is returned by the context manager. The objects appended to the list are arguments whose attributes mirror the arguments to showwarning(). The 'module' argument is to specify an alternative module to the module named 'warnings' and imported under that name. This argument is only useful when testing the warnings module itself.

Named constructor functions are also available, these are faster than using new(name): md5(), sha1(), sha224(), sha256(), sha384(), sha512(), blake2b(), blake2s(), sha3_224, sha3_256, sha3_384, sha3_512, shake_128, and shake_256. More algorithms may be available on your platform but the above are guaranteed to exist. See the algorithms_guaranteed and algorithms_available attributes to find out what algorithm names can be passed to new(). NOTE: If you want the adler32 or crc32 hash functions they are available in the zlib module. Choose your hash function wisely. Some have known collision weaknesses. sha384 and sha512 will be slow on 32 bit platforms. Hash objects have these methods: - update(data): Update the hash object with the bytes in data. Repeated calls are equivalent to a single call with the concatenation of all the arguments. - digest(): Return the digest of the bytes passed to the update() method so far as a bytes object. - hexdigest(): Like digest() except the digest is returned as a string of double length, containing only hexadecimal digits. - copy(): Return a copy (clone) of the hash object. This can be used to efficiently compute the digests of datas that share a common initial substring. For example, to obtain the digest of the byte string 'Nobody inspects the spammish repetition': >>> import hashlib >>> m = hashlib.md5() >>> m.update(b"Nobody inspects") >>> m.update(b" the spammish repetition") >>> m.digest() b'\xbbd\x9c\x83\xdd\x1e\xa5\xc9\xd9\xde\xc9\xa1\x8d\xf0\xff\xe9' More condensed: >>> hashlib.sha224(b"Nobody inspects the spammish repetition").hexdigest() 'a4337bc45a8fc544c03f52dc550cd6e1e87021bc896588bd79e901e2' �md5�sha1�sha224�sha256�sha384�sha512�blake2b�blake2s�sha3_224�sha3_256�sha3_384�sha3_512� shake_128� shake_256�new�algorithms_guaranteed�algorithms_available� pbkdf2_hmac� )� get_fips_modec C s dS )Nr � r r r � /usr/lib64/python3.6/hashlib.py�_hashlib_get_fips_modeI s r c C s� t }|j| �}|d k r|S �y2| dkrDdd l}|j |d< |d< �n| dkrjdd l}|j |d< |d< � n�| dkr�dd l}|j |d< |d < |j |d< |d< n�| dkr�dd l }|j |d < |d < |j |d < |d < nv| dk� r�dd l }|j |d< |j|d< nN| d k�rLdd l}|j|d< |j|d< |j|d< |j|d< |j|d< |j|d< W n tk �rd Y nX |j| �}|d k �r~|S td| ��d S ) N�SHA1r r �MD5r �SHA256r �SHA224r �SHA512r �SHA384r r r r r r r r r zunsupported hash type )r r )r r )r r r r )r r r r )r r > r r r r r r )�__builtin_constructor_cache�get�_sha1r �_md5r �_sha256r r �_sha512r r �_blake2r r �_sha3r r r r r r � ImportError� ValueError) �name�cache� constructorr r! r" r# r$ r% r r r �__get_builtin_constructorP sL r+ c C sZ t j� s| dkrt| �S y tt d| �}t j� s6|� |S ttfk rT t| �S X d S )Nr r r r Zopenssl_> r r r r )�_hashlibr r+ �getattr�AttributeErrorr' )r( �fr r r �__get_openssl_constructor{ s r0 � c K s t | �|f|�S )z�new(name, data=b'', **kwargs) - Return a new hashing object using the named algorithm; optionally initialized with data (which must be a bytes-like object). )r+ )r( �data�kwargsr r r �__py_new� s r4 c K s� t j� r(| }ddddddd�j| | �} n| dkr@t| �|f|�S y:|jd d �}t j| ||d �}t j� rx| |krx|j|� |S tk r� t j� r�� t| �|�S X d S )z�new(name, data=b'') - Return a new hashing object using the named algorithm; optionally initialized with data (which must be a bytes-like object). zsha3-224zsha3-256zsha3-384zsha3-512Zshake128Zshake256)r r r r r r r r �usedforsecurityT)r5 N> r r )r, r r r+ �popr Z _set_namer' )r( r2 r3 Z orig_namer5 Zretvalr r r � __hash_new� s, r7 N)r )�scryptz code for hash %s was not found.)r r r r r r r r r r r r r r )r r r r )r1 )r1 )�__doc__Z__always_supported�setr r �__all__r, r r r& r r+ r0 r4 r7 r Z __get_hash�unionZopenssl_md_meth_namesr r8 Z __func_name�globalsr' ZloggingZ exceptionr r r r �<module>6 s\ + ' bisect.cpython-36.opt-1.pyc 0000644 00000005166 15246273046 0011423 0 ustar 00 3 \# � @ sZ d Z d dd�ZeZd dd�ZeZddd�Zdd d �Zy dd lT W n ek rT Y nX dS )zBisection algorithms.� Nc C sd |dk rt d��|dkr t| �}x2||k rR|| d }|| | k rH|}q"|d }q"W | j||� dS )z�Insert item x in list a, and keep it sorted assuming a is sorted.

Based on RFC 854: TELNET Protocol Specification, by J. Postel and J. Reynolds Example: >>> from telnetlib import Telnet >>> tn = Telnet('www.python.org', 79) # connect to finger port >>> tn.write(b'guido\r\n') >>> print(tn.read_all()) Login Name TTY Idle When Where guido Guido van Rossum pts/2 <Dec 2 11:10> snag.cnri.reston.. >>> Note that read_all() won't read until eof -- it just reads some data -- but it guarantees to read at least one byte unless EOF is hit. It is possible to pass a Telnet object to a selector in order to wait until more data is available. Note that in this case, read_eager() may return b'' even if there was data on the socket, because the protocol negotiation may have eaten the data. This is why EOFError is needed in some cases to distinguish between "no data" and "connection closed" (since the socket also appears ready for reading when it is closed). To do: - option negotiation - timeout should be intrinsic to the connection object instead of an option on one of the read calls only � N)� monotonic�Telnet� � � � � � �� �� �� �� �� � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � �! �" �# �$ �% �& �' �( �) �* �+ �, �- �. �/ �0 �1 � � � � PollSelectorc @ s e Zd ZdZddejfdd�Zdejfdd�Zdd � Zd d � Z d d � Z dd� Z dd� Z dd� Z dd� Zd<dd�Zdd� Zdd� Zd d � Zd d � Zd d!� Zd"d#� Zd$d%� Zd&d'� Zd(d)� Zd*d+� Zd,d-� Zd.d/� Zd0d1� Z d2d3� Z d4d5� Z d=d6d7�Z d8d9� Z d:d;� Z!dS )>r a� Telnet interface class. An instance of this class represents a connection to a telnet server. The instance is initially not connected; the open() method must be used to establish a connection. Alternatively, the host name and optional port number can be passed to the constructor, too. Don't try to reopen an already connected instance. This class has many read_*() methods. Note that some of them raise EOFError when the end of the connection is read, because they can return an empty string for other reasons. See the individual doc strings. read_until(expected, [timeout]) Read until the expected string has been seen, or a timeout is hit (default is no timeout); may block. read_all() Read all data until EOF; may block. read_some() Read at least one byte or EOF; may block. read_very_eager() Read all data available already queued or on the socket, without blocking. read_eager() Read either data already queued or some data available on the socket, without blocking. read_lazy() Read all data in the raw queue (processing it first), without doing any socket I/O. read_very_lazy() Reads all data in the cooked queue, without doing any socket I/O. read_sb_data() Reads available data between SB ... SE sequence. Don't block. set_option_negotiation_callback(callback) Each time a telnet option is read on the input flow, this callback (if set) is called with the following parameters : callback(telnet socket, command, option) option will be chr(0) when there is no option. No other action is done afterwards by telnetlib. Nr c C sh t | _|| _|| _|| _d| _d| _d| _d| _d| _ d| _ d| _ d| _ d| _ |dk rd| j|||� dS )z�Constructor.

The first argument is a list of regular expressions, either compiled (re.RegexObject instances) or uncompiled (strings). The optional second argument is a timeout, in seconds; default is no timeout. Return a tuple of three items: the index in the list of the first regular expression that matches; the match object returned; and the text read up till and including the match. If EOF is read and no text was read, raise EOFError. Otherwise, when nothing matches, return (-1, None, text) where text is the text received so far (may be the empty string if a timeout happened). If a regular expression ends with a greedy match (e.g. '.*') or if more than one expression can match the same input, the results are undeterministic, and may depend on the I/O timing.

This module provides two interfaces, broadly similar to the builtin function compile(), which take program text, a filename and a 'mode' and: - Return code object if the command is complete and valid - Return None if the command is incomplete - Raise SyntaxError, ValueError or OverflowError if the command is a syntax error (OverflowError and ValueError can be produced by malformed literals). Approach: First, check if the source consists entirely of blank lines and comments; if so, replace it with 'pass', because the built-in parser doesn't always do the right thing for these. Compile three times: as is, with \n, and with \n\n appended. If it compiles as is, it's complete. If it compiles with one \n appended, we expect more. If it doesn't compile either way, we compare the error we get when compiling with \n or \n\n appended. If the errors are the same, the code is broken. But if the errors are different, we expect more. Not intuitive; not even guaranteed to hold in future releases; but this matches the compiler's behavior from Python 1.4 through 2.2, at least. Caveat: It is possible (but not likely) that the parser stops parsing with a successful outcome before reaching the end of the source; in this case, trailing symbols may be ignored instead of causing an error. For example, a backslash followed by two newlines may be followed by arbitrary garbage. This will be fixed once the API for the parser is better. The two interfaces are: compile_command(source, filename, symbol): Compiles a single command in the manner described above. CommandCompiler(): Instances of this class have __call__ methods identical in signature to compile_command; the difference is that if the instance compiles program text containing a __future__ statement, the instance 'remembers' and compiles all subsequent program texts with the statement in force. The module also provides another class: Compile(): Instances of this class act like the built-in function compile, but with 'memory' in the sense described above. � Nc C s g | ]}t t|��qS � )�getattr� __future__)�.0Zfnamer r � /usr/lib64/python3.6/codeop.py� <listcomp>= s r �compile_command�Compile�CommandCompileri c - C s* x8|j d�D ] }|j� }|r |d dkr P q W |dkr:d}d } }}d } } } y| |||�}W n" tk r� } zW Y d d }~X nX y| |d ||�} W n& tk r� } z | }W Y d d } ~ X nX y| |d ||�} W n& tk r� } z | }W Y d d } ~ X nX |�r|S | �r&t|�t|�k�r&|�d S )N� r �#�eval�passz )�split�strip� SyntaxError�repr) �compiler�source�filename�symbol�line�errZerr1Zerr2�code�code1�code2�er r r �_maybe_compileD s0 r c C s t | ||t�S )N)�compile�PyCF_DONT_IMPLY_DEDENT)r r r r r r �_compilee s r �<input>�singlec C s t t| ||�S )as Compile a command and determine whether it is incomplete.

This module provides generic, low- and high-level interfaces for creating temporary files and directories. All of the interfaces provided by this module can be used without fear of race conditions except for 'mktemp'. 'mktemp' is subject to race conditions and should not be used; it is provided for backward compatibility only. The default path names are returned as str. If you supply bytes as input, all return values will be in bytes. Ex: >>> tempfile.mkstemp() (4, '/tmp/tmptpu9nin8') >>> tempfile.mkdtemp(suffix=b'') b'/tmp/tmppbi8f0hy' This module also provides some data items to the user: TMP_MAX - maximum number of names that will be tried before giving up. tempdir - If this is set to a string before the first use of any routine from this module, it will be considered as another candidate location to store temporary files. �NamedTemporaryFile� TemporaryFile�SpooledTemporaryFile�TemporaryDirectory�mkstemp�mkdtemp�mktemp�TMP_MAX� gettempprefix�tempdir� gettempdir�gettempprefixb� gettempdirb� N)�Random� O_NOFOLLOW�O_BINARYi' Ztmp�lstat�statc C s t j| t j�}t j|� d S )N)�_os�open�O_RDONLY�close)�fn�fd� r � /usr/lib64/python3.6/tempfile.py�_statT s r c C s* y t | � W n tk r dS X dS d S )NFT)r �OSError)r r r r �_existsX s r c G s` d}xJ| D ]B}|dkrq t |t�r8|tkr2td��t}q |tkrHtd��t}q W |dkr\tS |S )zBLook at the type of all args and divine their implied return type.Nz1Can't mix bytes and non-bytes in path components.)� isinstance�bytes�str� TypeError)�argsZ return_type�argr r r �_infer_return_typea s r% c C sd t | ||�}|dkr|� }| dkr:|tkr0t} n tjt�} |dkrX|tkrRt� }nt� }| |||fS )z9Common parameter processing for most APIs in this module.N)r% r! �templater �fsencoder r )�prefix�suffix�dir� output_typer r r �_sanitize_paramsv s r, c @ s0 e Zd ZdZdZedd� �Zdd� Zdd� Zd S ) �_RandomNameSequencea, An instance of _RandomNameSequence generates an endless sequence of unpredictable strings which can safely be incorporated into file names.

The return value is a pair (fd, name) where fd is the file descriptor returned by os.open, and name is the filename. If 'suffix' is not None, the file name will end with that suffix, otherwise there will be no suffix. If 'prefix' is not None, the file name will begin with that prefix, otherwise a default prefix is used. If 'dir' is not None, the file will be created in that directory, otherwise a default directory is used. If 'text' is specified and true, the file is opened in text mode. Else (the default) the file is opened in binary mode. On some operating systems, this makes no difference. If any of 'suffix', 'prefix' and 'dir' are not None, they must be the same type. If they are bytes, the returned name will be bytes; str otherwise. The file is readable and writable only by the creating user ID. If the operating system uses permission bits to indicate whether a file is executable, the file is executable by no one. The file descriptor is not inherited by children of this process.

To enable this module, do: import cgitb; cgitb.enable() at the top of your script. The optional arguments to enable() are: display - if true, tracebacks are displayed in the web browser logdir - if set, tracebacks are written to files in this directory context - number of lines of source code to show for each stack frame format - 'text' or 'html' controls the output format By default, tracebacks are displayed but not saved, the context is 5 lines and the output format is 'html' (for backwards compatibility with the original use of this module) Alternatively, if you have caught an exception and want cgitb to display it for you, call cgitb.handler(). The optional argument to handler() is a 3-item tuple (etype, evalue, etb) just like the value of sys.exc_info(). The default handler displays output as HTML. � Nc C s dS )zAReturn a string that resets the CGI and browser to a known state.a' <!--: spam Content-Type: text/html <body bgcolor="#f0f0f8"><font color="#f0f0f8" size="-5"> --> <body bgcolor="#f0f0f8"><font color="#f0f0f8" size="-5"> --> --> </font> </font> </font> </script> </object> </blockquote> </pre> </table> </table> </table> </table> </table> </font> </font> </font>� r r r � /usr/lib64/python3.6/cgitb.py�reset# s r c C s | rd| d S dS d S )Nz<small>z</small>� r )�textr r r �small. s r c C s | rd| d S dS d S )Nz<strong>z </strong>r r )r r r r �strong4 s r c C s | rd| d S dS d S )Nz<font color="#909090">z</font>r r )r r r r �grey: s r c C s� | |krd|| fS | |j kr,d|j | fS d|j kr~|j d }t|�ti �krf| |kr~d|| fS nt|| �r~dt|| �fS dtfS )z9Find the value for a given name in the given environment.�local�global� __builtins__�builtinN)� f_globals�type�hasattr�getattr� __UNDEF__)�name�frame�locals�builtinsr r r �lookup@ s r c C s� g dddt f\}}}}}x�tj| �D ]�\}} } } } |tjkr>P |tjkr�| tjkr�|dkr�|t k r�t|| t �}|j|| ||f� q�t | ||�\} }|j| | |f� n"| dkr�||d 7 }|}nd\}}| }q$W |S )zEScan one logical line of Python and look up values of variables used.Nr �.)Nr ) r �tokenize�generate_tokens�NEWLINE�NAME�keyword�kwlistr �appendr )�readerr r �varsZ lasttoken�parent�prefix�valueZttype�token�start�end�line�wherer r r �scanvarsP s" r* � c " s� | \}}}t |t�r|j}dtjj� d d tj }tjtj� �}dt j j dt t j j t|��� dd|d | � d }d td d � d }g } tj||�} �xJ| D �]@\} � } } }}� r�tjj� �� d� t j j � �f }nd � }tj| �\}}}}d}| dk�r2dt t j j | �� tj||||dd� d� }i �| gf� �fdd� }t|| |�}dd||f g}|dk �r| | }x�|D ]�}td d tt|�� t|� �d }|�k�r�d|t j j|�f }|jd| � n&d |t j j|�f }|jd t|� � |d 7 }�q~W i g } } x�|D ]�\} } } | | k�r0�qd | | < | t k �r�| d-k�r^d!| t | � } n*| d"k�rrt | �} n| t | jd#�d. � } | jd$| t j j | �f � n| j| d% � �qW |jd ttd&j | ��� � | jd'd(j |� � q�W d)t t j j t|���t j j t|��f g}!xNt |�D ]B} | dd � d*k�r:�q t j j t || ��} |!jd+|| | f � �q W |dj | � dj |!� d,t j j dj t!j"|||��� S )/z9Return a nice HTML document describing a given traceback.zPython r z: z<body bgcolor="#f0f0f8">z<big><big>%s</big></big>z#ffffffz#6622aaz<br>z� <p>A problem occurred in a Python script.

This object captures the state of an SSL connection but does not provide any network IO itself. IO needs to be performed through separate "BIO" objects which are OpenSSL's IO abstraction layer. This class does not have a public constructor. Instances are returned by ``SSLContext.wrap_bio``. This class is typically used by framework authors that want to implement asynchronous IO for SSL through memory buffers. When compared to ``SSLSocket``, this object lacks the following features: * Any form of network IO, including methods such as ``recv`` and ``send``. * The ``do_handshake_on_connect`` and ``suppress_ragged_eofs`` machinery.

Function whathdr() recognizes various types of sound file headers. It understands almost all headers that SOX can decode. The return tuple contains the following items, in this order: - file type (as SOX understands it) - sampling rate (0 if unknown or hard to decode) - number of channels (0 if unknown or hard to decode) - number of frames in the file (-1 if unknown or hard to decode) - number of bits/sample, or 'U' for U-LAW, or 'A' for A-LAW If the file doesn't have a recognizable type, it returns None. If the file can't be opened, OSError is raised. To compute the total time, divide the number of frames by the sampling rate (a frame contains a sample for each channel). Function what() calls whathdr(). (It used to also use some heuristics for raw data, but this doesn't work very well.) Finally, the function test() is a simple main program that calls what() for all files mentioned on the argument list. For directory arguments it calls what() for all files in that directory. Default argument is "." (testing all files in the current directory). The option -r tells it to recurse down directories found inside explicitly given directories. �what�whathdr� )� namedtuple� SndHeadersz.filetype framerate nchannels nframes sampwidthz�The value for type indicates the data type and will be one of the strings 'aifc', 'aiff', 'au','hcom', 'sndr', 'sndt', 'voc', 'wav', '8svx', 'sb', 'ub', or 'ul'.zYThe sampling_rate will be either the actual value or 0 if unknown or difficult to decode.z^The number of channels or 0 if it cannot be determined or if the value is difficult to decode.z?The value for frames will be either the number of frames or -1.zAEither the sample size in bits or 'A' for A-LAW or 'U' for u-LAW.c C s t | �}|S )z Guess the type of a sound file.)r )�filename�res� r � /usr/lib64/python3.6/sndhdr.pyr 4 s c C sH t | d��4}|jd�}x"tD ]}|||�}|r t|� S q W dS Q R X dS )zRecognize sound headers.�rbi N)�open�read�testsr )r �f�hZtfr r r r r : s c C s� dd l }| jd�sd S | dd� dkr,d}n| dd� dkrBd}nd S |jd� y|j|d �}W n t|jfk rz d S X ||j� |j� |j� d|j � fS ) Nr s FORM� � s AIFC�aifcs AIFFZaiff�r) r � startswith�seekr �EOFError�Error� getframerate� getnchannels� getnframes� getsampwidth)r r r Zfmt�ar r r � test_aifcK s r c C s� | j d�rt}n| d d� dkr&t}nd S d}|| dd� �}|| dd� �}|| dd� �}|| dd � �}|| d d � �}d } |d kr�d } n$|d kr�d} n|dkr�d} d } nd} | | } | r�|| } nd} |||| | fS )Ns .snd� � ds.� dns.Zaur r � � � � �U� � �?)r r ���)r � get_long_be� get_long_le) r r �func�filetypeZhdr_sizeZ data_size�encoding�rate� nchannelsZ sample_sizeZ sample_bitsZ frame_sizeZnframer r r �test_au` s2 r1 c C sT | dd� dks | dd� dkr$d S t | dd� �}|rBd | }nd }d |d dd fS )N�A �E s FSSD� � s HCOM� � i"V r Zhcomr$ r r) )r* )r r Zdivisorr/ r r r � test_hcom� s r8 c C st | j d�sd S t| dd� �}d}d| ko4dk n rf| | dkrfd| |d }|rftd | �}d |dd d fS ) Ns Creative Voice Filer" � r i� r$ � r g ��.AZvocr r) )r � get_short_le�int)r r Zsbseekr/ Zratecoder r r �test_voc� s $ r= c C s� dd l }| jd� s4| dd� dks4| dd� dkr8d S |jd� y|j|d�}W n t|jfk rl d S X d |j� |j� |j� d|j � fS ) Nr s RIFFr r s WAVEr!

A configuration file consists of sections, lead by a "[section]" header, and followed by "name: value" entries, with continuations and such in the style of RFC 822. Intrinsic defaults can be specified by passing them into the ConfigParser constructor as a dictionary. class: ConfigParser -- responsible for parsing a list of configuration files, and managing the parsed database. methods: __init__(defaults=None, dict_type=_default_dict, allow_no_value=False, delimiters=('=', ':'), comment_prefixes=('#', ';'), inline_comment_prefixes=None, strict=True, empty_lines_in_values=True, default_section='DEFAULT', interpolation=<unset>, converters=<unset>): Create the parser. When `defaults' is given, it is initialized into the dictionary or intrinsic defaults. The keys must be strings, the values must be appropriate for %()s string interpolation. When `dict_type' is given, it will be used to create the dictionary objects for the list of sections, for the options within a section, and for the default values. When `delimiters' is given, it will be used as the set of substrings that divide keys from values. When `comment_prefixes' is given, it will be used as the set of substrings that prefix comments in empty lines. Comments can be indented. When `inline_comment_prefixes' is given, it will be used as the set of substrings that prefix comments in non-empty lines. When `strict` is True, the parser won't allow for any section or option duplicates while reading from a single source (file, string or dictionary). Default is True. When `empty_lines_in_values' is False (default: True), each empty line marks the end of an option. Otherwise, internal empty lines of a multiline option are kept as part of the value. When `allow_no_value' is True (default: False), options without values are accepted; the value presented for these is None. When `default_section' is given, the name of the special section is named accordingly. By default it is called ``"DEFAULT"`` but this can be customized to point to any other valid section name. Its current value can be retrieved using the ``parser_instance.default_section`` attribute and may be modified at runtime. When `interpolation` is given, it should be an Interpolation subclass instance. It will be used as the handler for option value pre-processing when using getters. RawConfigParser object s don't do any sort of interpolation, whereas ConfigParser uses an instance of BasicInterpolation. The library also provides a ``zc.buildbot`` inspired ExtendedInterpolation implementation. When `converters` is given, it should be a dictionary where each key represents the name of a type converter and each value is a callable implementing the conversion from string to the desired datatype. Every converter gets its corresponding get*() method on the parser object and section proxies. sections() Return all the configuration section names, sans DEFAULT. has_section(section) Return whether the given section exists. has_option(section, option) Return whether the given option exists in the given section. options(section) Return list of configuration options for the named section. read(filenames, encoding=None) Read and parse the iterable of named configuration files, given by name. A single filename is also allowed. Non-existing files are ignored. Return list of successfully read files. read_file(f, filename=None) Read and parse one configuration file, given as a file object. The filename defaults to f.name; it is only used in error messages (if f has no `name' attribute, the string `<???>' is used). read_string(string) Read configuration from a given string. read_dict(dictionary) Read configuration from a dictionary. Keys are section names, values are dictionaries with keys and values that should be present in the section. If the used dictionary type preserves order, sections and their keys will be added in order. Values are automatically converted to strings. get(section, option, raw=False, vars=None, fallback=_UNSET) Return a string value for the named option. All % interpolations are expanded in the return values, based on the defaults passed into the constructor and the DEFAULT section. Additional substitutions may be provided using the `vars' argument, which must be a dictionary whose contents override any pre-existing defaults. If `option' is a key in `vars', the value from `vars' is used. getint(section, options, raw=False, vars=None, fallback=_UNSET) Like get(), but convert value to an integer. getfloat(section, options, raw=False, vars=None, fallback=_UNSET) Like get(), but convert value to a float. getboolean(section, options, raw=False, vars=None, fallback=_UNSET) Like get(), but convert value to a boolean (currently case insensitively defined as 0, false, no, off for False, and 1, true, yes, on for True). Returns False or True. items(section=_UNSET, raw=False, vars=None) If section is given, return a list of tuples with (name, value) for each option in the section. Otherwise, return a list of tuples with (section_name, section_proxy) for each section, including DEFAULTSECT. remove_section(section) Remove the given file section and all its options. remove_option(section, option) Remove the given option from the given section. set(section, option, value) Set the given option. write(fp, space_around_delimiters=True) Write the configuration state in .ini format. If `space_around_delimiters' is True (the default), delimiters between keys and values are surrounded by spaces. � )�MutableMapping)� OrderedDict�ChainMapN�NoSectionError�DuplicateOptionError�DuplicateSectionError� NoOptionError�InterpolationError�InterpolationDepthError� InterpolationMissingOptionError�InterpolationSyntaxError� ParsingError�MissingSectionHeaderError� ConfigParser�SafeConfigParser�RawConfigParser� Interpolation�BasicInterpolation�ExtendedInterpolation�LegacyInterpolation� SectionProxy�ConverterMapping� DEFAULTSECT�MAX_INTERPOLATION_DEPTHZDEFAULT� c @ s& e Zd ZdZddd�Zdd� ZeZdS ) �Errorz'Base class for ConfigParser exceptions.� c C s || _ tj| |� d S )N)�message� Exception�__init__)�self�msg� r" �$/usr/lib64/python3.6/configparser.pyr � s zError.__init__c C s | j S )N)r )r r" r" r# �__repr__� s zError.__repr__N)r )�__name__� __module__� __qualname__�__doc__r r$ �__str__r" r" r" r# r � s r c @ s e Zd ZdZdd� ZdS )r z2Raised when no section matches a requested option.c C s$ t j| d|f � || _|f| _d S )NzNo section: %r)r r �section�args)r r* r" r" r# r � s zNoSectionError.__init__N)r% r& r' r( r r" r" r" r# r � s c @ s e Zd ZdZddd�ZdS )r a Raised when a section is repeated in an input source.

Each section in a configuration file contains a header, indicated by a name in square brackets (`[]'), plus key/value options, indicated by `name' and `value' delimited with a specific substring (`=' or `:' by default). Values can span multiple lines, as long as they are indented deeper than the first line of the value. Depending on the parser's mode, blank lines may be treated as parts of multiline values or ignored. Configuration files may include comments, prefixed by specific characters (`#' and `;' by default).

The purpose of this module is to support arithmetic using familiar "schoolhouse" rules and to avoid some of the tricky representation issues associated with binary floating point. The package is especially useful for financial applications or for contexts where users have expectations that are at odds with binary floating point (for instance, in binary floating point, 1.00 % 0.1 gives 0.09999999999999995 instead of 0.0; Decimal('1.00') % Decimal('0.1') returns the expected Decimal('0.00')). Here are some examples of using the decimal module: >>> from decimal import * >>> setcontext(ExtendedContext) >>> Decimal(0) Decimal('0') >>> Decimal('1') Decimal('1') >>> Decimal('-.0123') Decimal('-0.0123') >>> Decimal(123456) Decimal('123456') >>> Decimal('123.45e12345678') Decimal('1.2345E+12345680') >>> Decimal('1.33') + Decimal('1.27') Decimal('2.60') >>> Decimal('12.34') + Decimal('3.87') - Decimal('18.41') Decimal('-2.20') >>> dig = Decimal(1) >>> print(dig / Decimal(3)) 0.333333333 >>> getcontext().prec = 18 >>> print(dig / Decimal(3)) 0.333333333333333333 >>> print(dig.sqrt()) 1 >>> print(Decimal(3).sqrt()) 1.73205080756887729 >>> print(Decimal(3) ** 123) 4.85192780976896427E+58 >>> inf = Decimal(1) / Decimal(0) >>> print(inf) Infinity >>> neginf = Decimal(-1) / Decimal(0) >>> print(neginf) -Infinity >>> print(neginf + inf) NaN >>> print(neginf * inf) -Infinity >>> print(dig / 0) Infinity >>> getcontext().traps[DivisionByZero] = 1 >>> print(dig / 0) Traceback (most recent call last): ... ... ... decimal.DivisionByZero: x / 0 >>> c = Context() >>> c.traps[InvalidOperation] = 0 >>> print(c.flags[InvalidOperation]) 0 >>> c.divide(Decimal(0), Decimal(0)) Decimal('NaN') >>> c.traps[InvalidOperation] = 1 >>> print(c.flags[InvalidOperation]) 1 >>> c.flags[InvalidOperation] = 0 >>> print(c.flags[InvalidOperation]) 0 >>> print(c.divide(Decimal(0), Decimal(0))) Traceback (most recent call last): ... ... ... decimal.InvalidOperation: 0 / 0 >>> print(c.flags[InvalidOperation]) 1 >>> c.flags[InvalidOperation] = 0 >>> c.traps[InvalidOperation] = 0 >>> print(c.divide(Decimal(0), Decimal(0))) NaN >>> print(c.flags[InvalidOperation]) 1 >>> �Decimal�Context� DecimalTuple�DefaultContext� BasicContext�ExtendedContext�DecimalException�Clamped�InvalidOperation�DivisionByZero�Inexact�Rounded� Subnormal�Overflow� Underflow�FloatOperation�DivisionImpossible�InvalidContext�ConversionSyntax�DivisionUndefined� ROUND_DOWN� ROUND_HALF_UP�ROUND_HALF_EVEN� ROUND_CEILING� ROUND_FLOOR�ROUND_UP�ROUND_HALF_DOWN� ROUND_05UP� setcontext� getcontext� localcontext�MAX_PREC�MAX_EMAX�MIN_EMIN� MIN_ETINY� HAVE_THREADSZdecimalz1.70z2.4.2� N)� namedtuplezsign digits exponentc G s | S )N� )�argsr' r' �"/usr/lib64/python3.6/_pydecimal.py�<lambda>� s r* T� �? � l ��N�Zoi@�Tc @ s e Zd ZdZdd� ZdS )r a1 Base exception class. Used exceptions derive from this. If an exception derives from another exception besides this (such as Underflow (Inexact, Rounded, Subnormal) that indicates that it is only called if the others are present. This isn't actually used for anything, though. handle -- Called when context._raise_error is called and the trap_enabler is not set. First argument is self, second is the context. More arguments can be given, those being after the explanation in _raise_error (For example, context._raise_error(NewError, '(-x)!', self._sign) would call NewError().handle(context, self._sign).) To define a new exception, it should be sufficient to have it derive from DecimalException. c G s d S )Nr' )�self�contextr( r' r' r) �handle� s zDecimalException.handleN)�__name__� __module__� __qualname__�__doc__r0 r' r' r' r) r � s c @ s e Zd ZdZdS )r a) Exponent of a 0 changed to fit bounds. This occurs and signals clamped if the exponent of a result has been altered in order to fit the constraints of a specific concrete representation. This may occur when the exponent of a zero result would be outside the bounds of a representation, or when a large normal number would have an encoded exponent that cannot be represented. In this latter case, the exponent is reduced to fit and the corresponding number of zero digits are appended to the coefficient ("fold-down").

N)r1 r2 r3 r4 r' r' r' r) r R s c @ s e Zd ZdZdd� ZdS )r a Numerical overflow. This occurs and signals overflow if the adjusted exponent of a result (from a conversion or from an operation that is not an attempt to divide by zero), after rounding, would be greater than the largest value that can be handled by the implementation (the value Emax). The result depends on the rounding mode: For round-half-up and round-half-even (and for round-half-down and round-up, if implemented), the result of the operation is [sign,inf], where sign is the sign of the intermediate result. For round-down, the result is the largest finite number that can be represented in the current precision, with the sign of the intermediate result. For round-ceiling, the result is the same as for round-down if the sign of the intermediate result is 1, or is [0,inf] otherwise. For round-floor, the result is the same as for round-down if the sign of the intermediate result is 0, or is [1,inf] otherwise. In all cases, Inexact and Rounded will also be raised. c G s� |j ttttfkrt| S |dkrR|j tkr4t| S t|d|j |j |j d �S |dkr�|j t krlt| S t|d|j |j |j d �S d S )Nr% �9r- ) �roundingr r r r r< r r6 �prec�Emaxr )r. r/ r= r( r' r' r) r0 s s zOverflow.handleN)r1 r2 r3 r4 r0 r' r' r' r) r ] s c @ s e Zd ZdZdS )r ax Numerical underflow with result rounded to 0. This occurs and signals underflow if a result is inexact and the adjusted exponent of the result would be smaller (more negative) than the smallest value that can be handled by the implementation (the value Emin). That is, the result is both inexact and subnormal. The result after an underflow will be a subnormal number rounded, if necessary, so that its exponent is not less than Etiny. This may result in 0 with the sign of the intermediate result and an exponent of Etiny. In all cases, Inexact, Rounded, and Subnormal will also be raised.

If the signal is not trapped (default), mixing floats and Decimals is permitted in the Decimal() constructor, context.create_decimal() and all comparison operators. Both conversion and comparisons are exact. Any occurrence of a mixed operation is silently recorded by setting FloatOperation in the context flags. Explicit conversions with Decimal.from_float() or context.create_decimal_from_float() do not set the flag. Otherwise (the signal is trapped), only equality comparisons and explicit conversions are silent. All other mixed operations raise FloatOperation.

Assumes that elimination of special cases has already been performed: self and other must both be nonspecial; self must be positive and not numerically equal to 1; other must be nonzero. For efficiency, other._exp should not be too large, so that 10**abs(other._exp) is a feasible calculation.r� r% r- Nr� rQ r+ � r� � �] �A ry � r[ �d )r+ r r� r )ri rU rV r= r� r7 rO r� r6 �_nbitsrf r` �_decimal_lshift_exactr� rh � _log10_lb)r. r� �p�x�xc�xe�y�yc�yer� r� ZzerosZ last_digitr� Zemaxr� ru r5 Zxc_bits�rem�ar� r� Zstr_xcr' r' r) � _power_exact( s� : &&&& zDecimal._power_exactc C s@ |dk r| j |||�S t|�}|tkr*|S |dkr8t� }| j||�}|rL|S |sd| s`|jtd�S tS d}| jdkr�|j � r�|j � s�d}n| r�|jtd�S | j � } | s�|jdkr�t |dd�S t | S | j� r�|jdkr�t | S t |dd�S | tk�r�|j � �rZ|jdk�rd}n ||jk�r"|j}nt|�}| j| }|d|j k �rxd|j }|jt� n |jt� |jt� d|j }t |dd| |�S | j� }|j� �r�|jdk|dk k�r�t |dd�S t | S d}d} | j� |j� } |dk|jdkk�r | tt|j��k�rHt |d|jd �}n,|j� } | tt| ��k�rHt |d| d �}|dk�r�| j||jd �}|dk �r�|dk�r�t d|j|j�}d } |dk�r:|j} t | �} | j| j }}t |�}|j|j }}|j dk�r�| }d }xJt ||||| | �\}}|d d tt|��| d �r P |d 7 }�q�W t |t|�|�}| �r2|j � �r2t|j�|jk�r�|jd t|j� }t |j|jd| |j| �}|j � }|j!� xt"D ]}d|j#|< �q�W |j$|�}|jt� |j%t& �r�|jt'� |j%t( �r |jt(d |j� x:t't&ttt)fD ] }|j%| �r|j|� �qW n |j$|�}|S )aH Return self ** other [ % modulo]. With two arguments, compute self**other. With three arguments, compute (self**other) % modulo. For the three argument form, the following restrictions on the arguments hold: - all three arguments must be integral - other must be nonnegative - either self or other (or both) must be nonzero - modulo must be nonzero and must have at most p digits, where p is the context precision. If any of these restrictions is violated the InvalidOperation flag is raised. The result of pow(self, other, modulo) is identical to the result that would be obtained by computing (self**other) % modulo with unbounded precision, but is computed more efficiently. It is always exact.

The min_width keyword argument gives the minimum length of the result, which will be padded on the left with zeros if necessary. If necessary, the zero padding adds an extra '0' on the left to avoid a leading thousands separator. For example, inserting commas every three digits in '123456', with min_width=8, gives '0,123,456', even though that has length 9. r� r� r% z group length should be positiver- rQ N)r� rl r� r� rf rm rn �reversed)rx ry � min_width�sepr� �groupsr, r' r' r) �_insert_thousands_sep� s $$r� c C s$ | rdS |d dkr |d S dS dS )zDetermine sign character.rT r= z +rS Nr' )� is_negativery r' r' r) rv � s rv c C s� t | |�}|s|d r"|d | }|dks6|d dkr\ddddd�|d }|d j||�7 }|d d krp|d 7 }|d r�|d t|� t|� }nd}t|||�}t||| |�S ) ac Format a number, given the following data: is_negative: true if the number is negative, else false intpart: string of digits that must appear before the decimal point fracpart: string of digits that must come after the point exp: exponent, as an integer spec: dictionary resulting from parsing the format specifier This function uses the information in spec to: insert separators (decimal separator and thousands separators) format the sign format the exponent add trailing '%' for the '%' type zero-pad if necessary fill and align if necessary Zaltr� r% rk rt r� r� )r� r� rr rq z{0}{1:+}rp r� r� )rv �formatrf r� rw )r� rv rw rV ry r= Zecharr� r' r' r) rx � s rx ZInfz-Infr� l l ���� l������N�Zoi���)N)F)r% )r )r )FF)Fi���)N)r- r� )}r4 �__all__r1 rD � __version__Z__libmpdec_version__Zmathrz Znumbersr� rE � collectionsr& Z _namedtupler � ImportErrorr r r r r r r r r$ �maxsizer r! r" r# �ArithmeticErrorr r r r �ZeroDivisionErrorr r r r r r r r r rr r r r� r� rJ r] rB rF rL �hasattrrK rG r r r r r6 �Number�registerrN r ri r� rU r} r r r� r� r� r� rJ rG r� r� r� r� r9 r r r� r� r r r �re�compile�VERBOSE� IGNORECASEr� ra r� r� �DOTALLr� Zlocaler� ru rw r� r� rv rx rF rE r: r5 r r4 r< � hash_info�modulusr� ra r� r� r� r� r� r' r' r' r) �<module>q s� & . ^ 0",# %$+ * P % ) random.cpython-36.opt-2.pyc 0000644 00000030767 15246273046 0011440 0 ustar 00 3 \2k � @ s� d dl mZ d dlmZmZ d dlm Z m Z m ZmZmZ d dlmZmZmZmZ d dlm Z d dl m Z m!Z" d dl#m$Z% d dl&Z'd dl(Z)d d d d d ddddddddddddddd d d d d gZ*d!e d1� ed#� Z+d#e Z,e d$�Z-d%e d&� Z.d'Z/d(e/ Z0d dl1Z1G d)d � d e1j2�Z2G d*d � d e2�Z3d+d,� Z4d2d.d/�Z5e2� Z6e6j7Z7e6j8Z8e6j9Z9e6j:Z:e6j;Z;e6j<Z<e6j=Z=e6j>Z>e6j?Z?e6j@Z@e6jAZAe6jBZBe6jCZCe6jDZDe6jEZEe6jFZFe6jGZGe6jHZHe6jIZIe6jJZJe6jKZKe6jLZLeMd0k�r�e5� dS )3� )�warn)� MethodType�BuiltinMethodType)�log�exp�pi�e�ceil)�sqrt�acos�cos�sin)�urandom)�Set�Sequence)�sha512N�Random�seed�random�uniform�randint�choice�sample� randrange�shuffle� normalvariate�lognormvariate� expovariate�vonmisesvariate� gammavariate� triangular�gauss� betavariate� paretovariate�weibullvariate�getstate�setstate� getrandbits�choices� SystemRandom� g �?g @g @g �?g @�5 � c s e Zd ZdZd:dd�Zd;� fdd� Z� fdd �Z� fd d �Zd d � Zdd� Z dd� Z dde fdd�Z dd� Z e de> eeefdd�Zdd� Zd<dd �Zd d � Zd=ddd �d d!�Zd"d#� Zd>d&d'�Zd(d)� Zd*d+� Zd,d-� Zd.d/� Z d0d1� Z d2d3� Z d4d5� Z d6d7� Z d8d9� Z!� Z"S )?r � Nc C s | j |� d | _d S )N)r � gauss_next)�self�x� r1 � /usr/lib64/python3.6/random.py�__init__W s zRandom.__init__r, c s� |dkr�t |ttf�r�t |t�r*|jd�n|}|rBt|d �d> nd}x"tt|�D ]}d| |A d@ }qRW |t|�N }|d kr�d n|}|dkr�t |tttf�r�t |t�r�|j� }|t |�j � 7 }t j |d�}t � j|� d | _d S ) N� zlatin-1r � iCB l ���� r, �big������)� isinstance�str�bytes�decode�ord�map�len� bytearray�encode�_sha512Zdigest�int� from_bytes�superr r. )r/ �a�versionr0 �c)� __class__r1 r2 r ` s z Random.seedc s | j t� j� | jfS )N)�VERSIONrE r% r. )r/ )rI r1 r2 r% � s zRandom.getstatec s� |d }|dkr*|\}}| _ t� j|� nt|dkr�|\}}| _ ytdd� |D ��}W n( tk r| } z t|�W Y d d }~X nX t� j|� ntd|| jf ��d S )Nr r- r, c s s | ]}|d V qdS )r, � Nl r1 )�.0r0 r1 r1 r2 � <genexpr>� s z"Random.setstate.<locals>.<genexpr>z?state with version %s passed to Random.setstate() of version %s)r. rE r& �tuple� ValueError� TypeErrorrJ )r/ �staterG Z internalstater )rI r1 r2 r& � s zRandom.setstatec C s | j � S )N)r% )r/ r1 r1 r2 � __getstate__� s zRandom.__getstate__c C s | j |� d S )N)r& )r/ rQ r1 r1 r2 � __setstate__� s zRandom.__setstate__c C s | j f | j� fS )N)rI r% )r/ r1 r1 r2 � __reduce__� s zRandom.__reduce__r4 c C s ||�}||krt d��|d kr:|dkr2| j|�S t d��||�}||krRt d��|| }|dkrx|dkrx|| j|� S |dkr�t d|||f ��||�}||kr�t d��|dkr�|| d | } n"|dk r�|| d | } nt d��| dkr�t d��||| j| � S ) Nz!non-integer arg 1 for randrange()r zempty range for randrange()z non-integer stop for randrange()r4 z'empty range for randrange() (%d,%d, %d)z non-integer step for randrange()zzero step for randrange())rO � _randbelow) r/ �start�stop�step�_intZistartZistop�widthZistep�nr1 r1 r2 r � s4 zRandom.randrangec C s | j ||d �S )Nr4 )r )r/ rF �br1 r1 r2 r � s zRandom.randintc C s� | j }| j}||�|ks$||�|krN|j� } || �} x| |krH|| �} q6W | S ||krltd� ||� | �S |dkr|td��|| } || | } |� } x| | kr�|� } q�W || | �| S )Nz�Underlying random() generator does not supply enough bits to choose from a population range this large.

The optional *protocol* argument tells the pickler to use the given protocol; supported protocols are 0, 1, 2, 3 and 4. The default protocol is 3; a backward-incompatible protocol designed for Python 3. Specifying a negative protocol version selects the highest protocol version supported. The higher the protocol used, the more recent the version of Python needed to read the pickle produced. The *file* argument must have a write() method that accepts a single bytes argument. It can thus be a file object opened for binary writing, an io.BytesIO instance, or any other custom object that meets this interface. If *fix_imports* is True and *protocol* is less than 3, pickle will try to map the new Python 3 names to the old module names used in Python 2, so that the pickle data stream is readable with Python 2.

data stream. The protocol version of the pickle is detected automatically, so no proto argument is needed. The argument *file* must have two methods, a read() method that takes an integer argument, and a readline() method that requires no arguments. Both methods should return bytes. Thus *file* can be a binary file object opened for reading, an io.BytesIO object, or any other custom object that meets this interface. The file-like object must have two methods, a read() method that takes an integer argument, and a readline() method that requires no arguments. Both methods should return bytes. Thus file-like object can be a binary file object opened for reading, a BytesIO object, or any other custom object that meets this interface. Optional keyword arguments are *fix_imports*, *encoding* and *errors*, which are used to control compatibility support for pickle stream generated by Python 2. If *fix_imports* is True, pickle will try to map the old Python 2 names to the new names used in Python 3. The *encoding* and *errors* tell pickle how to decode 8-bit string instances pickled by Python 2; these default to 'ASCII' and 'strict', respectively. *encoding* can be 'bytes' to read theses 8-bit string instances as bytes objects. r N) r� �_file_readliner� � _file_readr� rK rL r� r� )r r� r� rK rL r r r r � s z_Unpickler.__init__c C s� t | d�s td| jjf ��t| j| j�| _| jj| _| jj | _ g | _ g | _ | j j | _ d| _ | j}| j}y*x$|d�}|s|t�||d | � qlW W n" tk r� } z|jS d}~X nX dS )z�Read a pickled object representation from the open file.

OptionParser instances should use one of the HelpFormatter subclasses for formatting help; by default IndentedHelpFormatter is used. Instance attributes: parser : OptionParser the controlling OptionParser instance indent_increment : int the number of columns to indent per nesting level max_help_position : int the maximum starting column for option help text help_position : int the calculated starting column for option help text; initially the same as the maximum width : int total number of columns for output (pass None to constructor for this value to be taken from the $COLUMNS environment variable) level : int current indentation level current_indent : int current indentation level (in columns) help_width : int number of columns available for option help text (calculated) default_tag : str text to replace with each option's default value, "%default" by default. Set to false value to disable default value expansion. option_strings : { Option : str } maps Option instances to the snippet of help text explaining the syntax of that option, e.g. "-h, --help" or "-fFILE, --file=FILE" _short_opt_fmt : str format string controlling how short options with values are printed in help text. Must be either "%s%s" ("-fFILE") or "%s %s" ("-f FILE"), because those are the two syntaxes that Optik supports. _long_opt_fmt : str similar but for long options; must be either "%s %s" ("--file FILE") or "%s=%s" ("--file=FILE").

Instance attributes: usage : string a usage string for your program. Before it is displayed to the user, "%prog" will be expanded to the name of your program (self.prog or os.path.basename(sys.argv[0])). prog : string the name of the current program (to override os.path.basename(sys.argv[0])). description : string A paragraph of text giving a brief overview of your program. optparse reformats this paragraph to fit the current terminal width and prints it when the user requests help (after usage, but before the list of options). epilog : string paragraph of help text to print after option help option_groups : [OptionGroup] list of option groups in this parser (option groups are irrelevant for parsing the command-line, but very useful for generating help) allow_interspersed_args : bool = true if true, positional arguments may be interspersed with options. Assuming -a and -b each take a single argument, the command-line -ablah foo bar -bboo baz will be interpreted the same as -ablah -bboo -- foo bar baz If this flag were false, that command line would be interpreted as -ablah -- foo bar -bboo baz -- ie. we stop processing options as soon as we see the first non-option argument. (This is the tradition followed by Python's getopt module, Perl's Getopt::Std, and other argument- parsing libraries, but it is generally annoying to users.) process_default_values : bool = true if true, option default values are processed similarly to option values from the command line: that is, they are passed to the type-checking function for the option's type (as long as the default value is a string). (This really only matters if you have defined custom types; see SF bug #955889.) Set it to false to restore the behaviour of Optik 1.4.1 and earlier. rargs : [string] the argument list currently being parsed. Only set when parse_args() is active, and continually trimmed down as we consume arguments. Mainly there for the benefit of callback options. largs : [string] the list of leftover arguments that we have skipped while parsing options. If allow_interspersed_args is false, this list is always empty. values : Values the set of option values currently being accumulated. Only set when parse_args() is active. Also mainly for callbacks. Because of the 'rargs', 'largs', and 'values' attributes, OptionParser is not thread-safe. If, for some perverse reason, you need to parse command-line arguments simultaneously in different threads, use different OptionParser instances.

This class adds support for 'chat' style protocols - where one side sends a 'command', and the other sends a response (examples would be the common internet protocols - smtp, nntp, ftp, etc..). The handle_read() method looks at the input stream for the current 'terminator' (usually '\r\n' for single-line responses, '\r\n.\r\n' for multi-line output), calling self.found_terminator() on its receipt. for example: Say you build an async nntp client using this class. At the start of the connection, you'll have self.terminator set to '\r\n', in order to process the single-line greeting. Just before issuing a 'LIST' command you'll set it to '\r\n.\r\n'. The output of the LIST command will be accumulated (using your own 'collect_incoming_data' method) up to the terminator, and then control will be returned to you - by calling your self.found_terminator() method. � N)�dequec @ s� e Zd ZdZdZdZdZdZd(dd�Zdd � Z d d � Z d d � Z dd� Z dd� Z dd� Zdd� Zdd� Zdd� Zdd� Zd d � Zd d � Zd d!� Zd"d#� Zd$d%� Zd&d'� ZdS ))� async_chatz�This is an abstract class.

Optional casefold is a flag specifying whether a lowercase alphabet is acceptable as input. For security purposes, the default is False. RFC 3548 allows for optional mapping of the digit 0 (zero) to the letter O (oh), and for optional mapping of the digit 1 (one) to either the letter I (eye) or letter L (el). The optional argument map01 when not None, specifies which letter the digit 1 should be mapped to (when map01 is not None, the digit 0 is always mapped to the letter O). For security purposes the default is None, so that 0 and 1 are not allowed in the input. The result is returned as a bytes object. A binascii.Error is raised if the input is incorrectly padded or if there are non-alphabet characters present in the input.

This feature is not supported by the "standard" Adobe encoding. wrapcol controls whether the output should have newline (b'\n') characters added to it. If this is non-zero, each output line will be at most this many characters long. pad controls whether the input is padded to a multiple of 4 before encoding. Note that the btoa implementation always pads. adobe controls whether the encoded byte sequence is framed with <~ and ~>, which is used by the Adobe implementation.

Called internally from sysconfig with a mutable mapping containing name/value pairs parsed from the configured makefile used to build this interpreter. Returns the mapping updated as needed to reflect the environment in which the interpreter is running; in the case of a Python from a binary installer, the installed environment may be very different from the build environment, i.e. different OS levels, different built tools, different available CPU architectures. This customization is performed whenever distutils.sysconfig.get_config_vars() is first called. It may be used in environments where no compilers are present, i.e. when installing pure Python dists. Customization of compiler paths and detection of unavailable archs is deferred until the first extension module build is requested (in distutils.sysconfig.customize_compiler).

An IFF chunk (used in formats such as AIFF, TIFF, RMFF (RealMedia File Format)) has the following structure: +----------------+ | ID (4 bytes) | +----------------+ | size (4 bytes) | +----------------+ | data | | ... | +----------------+ The ID is a 4-byte string which identifies the type of chunk. The size field (a 32-bit value, encoded using big-endian byte order) gives the size of the whole chunk, including the 8-byte header. Usually an IFF-type file consists of one or more chunks. The proposed usage of the Chunk class defined here is to instantiate an instance at the start of each chunk and read from the instance until it reaches the end, after which a new instance can be instantiated. At the end of the file, creating a new instance will fail with an EOFError exception. Usage: while True: try: chunk = Chunk(file) except EOFError: break chunktype = chunk.getname() while True: data = chunk.read(nbytes) if not data: pass # do something with data The interface is file-like. The implemented methods are: read, close, seek, tell, isatty. Extra methods are: skip() (called by close, skips to the end of the chunk), getname() (returns the name (ID) of the chunk) The __init__ method has one required argument, a file-like object (including a chunk instance), and one optional argument, a flag which specifies whether or not chunks are aligned on 2-byte boundaries. The default is 1, i.e. aligned. c @ sZ e Zd Zddd�Zdd� Zdd� Zd d � Zd d � Zddd�Zdd� Z ddd�Z dd� Z dS ) �ChunkTFc C s� dd l }d| _|| _|r d}nd}|| _|jd�| _t| j�dk rFt�y |j|d |jd��d | _ W n |j k r� t�Y nX |r�| j d | _ d| _ y| jj � | _ W n ttfk r� d| _Y nX d| _d S ) N� F�>�<� �L� T)�struct�closed�align�file�read� chunkname�len�EOFErrorZ unpack_from� chunksize�error� size_read�tell�offset�AttributeError�OSError�seekable)�selfr r Z bigendianZ inclheaderr Zstrflag� r � /usr/lib64/python3.6/chunk.py�__init__4 s, zChunk.__init__c C s | j S )z*Return the name (ID) of the current chunk.)r )r r r r �getnameN s z Chunk.getnamec C s | j S )z%Return the size of the current chunk.)r )r r r r �getsizeR s z Chunk.getsizec C s | j s z | j� W d d| _ X d S )NT)r �skip)r r r r �closeV s z Chunk.closec C s | j rtd��dS )Nz I/O operation on closed fileF)r � ValueError)r r r r �isatty] s z Chunk.isattyr c C sv | j rtd��| js td��|dkr0|| j }n|dkrB|| j }|dk sT|| jkrXt�| jj| j | d� || _dS )z�Seek to specified position into the chunk.

Implements temporary breakpoints, ignore counts, disabling and (re)-enabling, and conditionals. Breakpoints are indexed by number through bpbynumber and by the file,line tuple using bplist. The former points to a single instance of class Breakpoint. The latter points to a list of such instances since there may be more than one breakpoint per line. r NFc C s� || _ d | _|| _|| _|| _|| _d| _d| _d| _t j | _ t j d7 _ | j j | � ||f| jkr|| j||f j | � n| g| j||f< d S )NTr r )rb �func_first_executable_linerl r% rK ra �enabled�ignore�hitsr �nextrJ rp r` re )r rl r% rK ra rb r r r r � s zBreakpoint.__init__c C s> | j | jf}d | j| j< | j| j| � | j| s:| j|= d S )N)rl r% rp rJ re rf )r �indexr r r rh s zBreakpoint.deleteMec C s d| _ d S )NT)r� )r r r r �enable s zBreakpoint.enablec C s d| _ d S )NF)r� )r r r r �disable s zBreakpoint.disablec C s" |d krt j}t| j� |d� d S )N)rl )rX �stdoutr- �bpformat)r �outr r r �bpprint s zBreakpoint.bpprintc C s� | j r d}nd}| jr |d }n|d }d| j|| j| jf }| jrT|d| jf 7 }| jrj|d| jf 7 }| jr�| jdkr�d }nd }|d | j|f 7 }|S ) Nzdel zkeep zyes zno z %-4dbreakpoint %s at %s:%dz stop only if %sz ignore next %d hitsr r� � z" breakpoint already hit %d time%s)rK r� rJ rl r% ra r� r� )r ZdispZretZssr r r r� s$ zBreakpoint.bpformatc C s d| j | j| jf S )Nzbreakpoint %s at %s:%s)rJ rl r% )r r r r �__str__6 s zBreakpoint.__str__)FNN)N)r r r r r� re rp r rh r� r� r� r� r� r r r r r � s c C sN | j s| j|jkrdS dS |jj| j kr,dS | js:|j| _| j|jkrJdS dS )z;Check whether we should break here because of `b.funcname`.FT)rb r% rF r7 r� r� )�br/ r r r � checkfuncname; s r� c C s� t j| |f }x�|D ]�}|js qt||�s,q| jd7 _|jsf|jdkr\| jd8 _qq�|dfS qy<t|j|j|j �}|r�|jdkr�| jd8 _n|dfS W q |dfS qW dS )z�Determine which breakpoint for this file:line is to be acted upon.

Formatter objects transform an abstract flow of formatting events into specific output events on writer objects. Formatters manage several stack structures to allow various properties of a writer object to be changed and restored; writers need not be able to handle relative changes nor any sort of ``change back'' operation. Specific writer properties which may be controlled via formatter objects are horizontal alignment, font, and left margin indentations. A mechanism is provided which supports providing arbitrary, non-exclusive style settings to a writer as well. Additional interfaces facilitate formatting events which are not reversible, such as paragraph separation. Writer objects encapsulate device interfaces. Abstract devices, such as file formats, are supported as well as physical devices. The provided implementations all work with abstract devices. The interface makes available mechanisms for setting the properties which formatter objects manage and inserting data into the output. � Nz"the formatter module is deprecated� )� stacklevelc @ s� e Zd ZdZd(dd�Zdd� Zdd� Zd d � Zd)d d �Zd d� Z dd� Z dd� Z dd� Z dd� Z dd� Zdd� Zdd � Zd d � Zd d � Zd!d"� Zd*d$d%�Zd+d&d'�ZdS ),� NullFormattera= A formatter which does nothing. If the writer parameter is omitted, a NullWriter instance is created. No methods of the writer are called by NullFormatter instances. Implementations should inherit from this class if implementing a writer interface but don't need to inherit any implementation.

The public interface consists of the wrap() and fill() methods; the other methods are just there for subclasses to override in order to tweak the default behaviour. If you want to completely replace the main wrapping algorithm, you'll probably have to override _wrap_chunks(). Several instance attributes control various aspects of wrapping: width (default: 70) the maximum width of wrapped lines (unless break_long_words is false) initial_indent (default: "") string that will be prepended to the first line of wrapped output. Counts towards the line's width. subsequent_indent (default: "") string that will be prepended to all lines save the first of wrapped output; also counts towards each line's width. expand_tabs (default: true) Expand tabs in input text to spaces before further processing. Each tab will become 0 .. 'tabsize' spaces, depending on its position in its line. If false, each tab is treated as a single character. tabsize (default: 8) Expand tabs in input text to 0 .. 'tabsize' spaces, unless 'expand_tabs' is false. replace_whitespace (default: true) Replace all whitespace characters in the input text by spaces after tab expansion. Note that if expand_tabs is false and replace_whitespace is true, every tab will be converted to a single space! fix_sentence_endings (default: false) Ensure that sentence-ending punctuation is always followed by two spaces. Off by default because the algorithm is (unavoidably) imperfect. break_long_words (default: true) Break words longer than 'width'. If false, those words will not be broken, and some lines might be longer than 'width'. break_on_hyphens (default: true) Allow breaking hyphenated words. If true, wrapping will occur preferably on whitespaces and right after hyphens part of compound words. drop_whitespace (default: true) Drop leading and trailing whitespace from lines. max_lines (default: None) Truncate wrapped lines. placeholder (default: ' [...]') Append to the last line of truncated text. � z [\w!"\'&.,?]z[^\d\W]z[%s]z[^� Na� ( # any whitespace %(ws)s+ | # em-dash between words (?<=%(wp)s) -{2,} (?=\w) | # word, possibly hyphenated %(nws)s+?

As an example, the text Look, goof-ball -- use the -b option! breaks into the following chunks: 'Look,', ' ', 'goof-', 'ball', ' ', '--', ' ', 'use', ' ', 'the', ' ', '-b', ' ', 'option!' if break_on_hyphens is True, or in: 'Look,', ' ', 'goof-ball', ' ', '--', ' ', 'use', ' ', 'the', ' ', '-b', ' ', option!' otherwise.

This can be used to make triple-quoted strings line up with the left edge of the display, while still presenting them in the source code in indented form. Note that tabs and spaces are both treated as whitespace, but they are not equal: the lines " hello" and "\thello" are considered to have no common leading whitespace.

changes. Each line is of the form: FeatureName = "_Feature(" OptionalRelease "," MandatoryRelease "," CompilerFlag ")" where, normally, OptionalRelease < MandatoryRelease, and both are 5-tuples of the same form as sys.version_info: (PY_MAJOR_VERSION, # the 2 in 2.1.0a3; an int PY_MINOR_VERSION, # the 1; an int PY_MICRO_VERSION, # the 0; an int PY_RELEASE_LEVEL, # "alpha", "beta", "candidate" or "final"; string PY_RELEASE_SERIAL # the 3; an int ) OptionalRelease records the first release in which from __future__ import FeatureName was accepted. In the case of MandatoryReleases that have not yet occurred, MandatoryRelease predicts the release in which the feature will become part of the language. Else MandatoryRelease records when the feature became part of the language; in releases at or after that, modules no longer need from __future__ import FeatureName to use the feature in question, but may continue to use such imports. MandatoryRelease may also be None, meaning that a planned feature got dropped. Instances of class _Feature have two corresponding methods, .getOptionalRelease() and .getMandatoryRelease(). CompilerFlag is the (bitfield) flag that should be passed in the fourth argument to the builtin function compile() to enable the feature in dynamically compiled code. This flag is stored in the .compiler_flag attribute on _Future instances. These values must match the appropriate #defines of CO_xxx flags in Include/compile.h. No feature line is ever to be deleted from this file. � nested_scopes� generators�division�absolute_import�with_statement�print_function�unicode_literals�barry_as_FLUFL�generator_stop�all_feature_names� � i i @ i � i i i i c @ s, e Zd Zdd� Zdd� Zdd� Zdd� Zd S ) �_Featurec C s || _ || _|| _d S )N)�optional� mandatory� compiler_flag)�selfZoptionalReleaseZmandatoryReleaser � r �"/usr/lib64/python3.6/__future__.py�__init__O s z_Feature.__init__c C s | j S )z�Return first release in which this feature was recognized.

The completer completes keywords, built-ins and globals in a selectable namespace (which defaults to __main__); when completing NAME.NAME..., it evaluates (!) the expression up to the last dot and completes its attributes. It's very cool to do "import sys" type "sys.", hit the completion key (twice), and see the list of names defined by the sys module! Tip: to use the tab key as the completion key, call readline.parse_and_bind("tab: complete") Notes: - Exceptions raised by the completer function are *ignored* (and generally cause the completion to fail). This is a feature -- since readline sets the tty device in raw (or cbreak) mode, printing a traceback wouldn't work well without some complicated hoopla to save, reset and restore the tty state. - The evaluation of the NAME.NAME... form may cause arbitrary application defined code to be executed if an object with a __getattr__ hook is found. Since it is the responsibility of the application (or the user) to enable this feature, I consider this an acceptable risk. More complicated expressions (e.g. function calls or indexing operations) are *not* evaluated. - When the original stdin is not a tty device, GNU readline is never used, and this module (and the readline module) are silently inactive. � N� Completerc @ s6 e Zd Zd dd�Zdd� Zdd� Zdd � Zd d � ZdS ) r Nc C s8 |rt |t� rtd��|dkr(d| _n d| _|| _dS )a� Create a new completer for the command line.

Named constructor functions are also available, these are faster than using new(name): md5(), sha1(), sha224(), sha256(), sha384(), sha512(), blake2b(), blake2s(), sha3_224, sha3_256, sha3_384, sha3_512, shake_128, and shake_256. More algorithms may be available on your platform but the above are guaranteed to exist. See the algorithms_guaranteed and algorithms_available attributes to find out what algorithm names can be passed to new(). NOTE: If you want the adler32 or crc32 hash functions they are available in the zlib module. Choose your hash function wisely. Some have known collision weaknesses. sha384 and sha512 will be slow on 32 bit platforms. Hash objects have these methods: - update(data): Update the hash object with the bytes in data. Repeated calls are equivalent to a single call with the concatenation of all the arguments. - digest(): Return the digest of the bytes passed to the update() method so far as a bytes object. - hexdigest(): Like digest() except the digest is returned as a string of double length, containing only hexadecimal digits. - copy(): Return a copy (clone) of the hash object. This can be used to efficiently compute the digests of datas that share a common initial substring. For example, to obtain the digest of the byte string 'Nobody inspects the spammish repetition': >>> import hashlib >>> m = hashlib.md5() >>> m.update(b"Nobody inspects") >>> m.update(b" the spammish repetition") >>> m.digest() b'\xbbd\x9c\x83\xdd\x1e\xa5\xc9\xd9\xde\xc9\xa1\x8d\xf0\xff\xe9' More condensed: >>> hashlib.sha224(b"Nobody inspects the spammish repetition").hexdigest() 'a4337bc45a8fc544c03f52dc550cd6e1e87021bc896588bd79e901e2' �md5�sha1�sha224�sha256�sha384�sha512�blake2b�blake2s�sha3_224�sha3_256�sha3_384�sha3_512� shake_128� shake_256�new�algorithms_guaranteed�algorithms_available� pbkdf2_hmac� )� get_fips_modec C s dS )Nr � r r r � /usr/lib64/python3.6/hashlib.py�_hashlib_get_fips_modeI s r c C s� t }|j| �}|d k r|S �y2| dkrDdd l}|j |d< |d< �n| dkrjdd l}|j |d< |d< � n�| dkr�dd l}|j |d< |d < |j |d< |d< n�| dkr�dd l }|j |d < |d < |j |d < |d < nv| dk� r�dd l }|j |d< |j|d< nN| d k�rLdd l}|j|d< |j|d< |j|d< |j|d< |j|d< |j|d< W n tk �rd Y nX |j| �}|d k �r~|S td| ��d S ) N�SHA1r r �MD5r �SHA256r �SHA224r �SHA512r �SHA384r r r r r r r r r zunsupported hash type )r r )r r )r r r r )r r r r )r r > r r r r r r )�__builtin_constructor_cache�get�_sha1r �_md5r �_sha256r r �_sha512r r �_blake2r r �_sha3r r r r r r � ImportError� ValueError) �name�cache� constructorr r! r" r# r$ r% r r r �__get_builtin_constructorP sL r+ c C sZ t j� s| dkrt| �S y tt d| �}t j� s6|� |S ttfk rT t| �S X d S )Nr r r r Zopenssl_> r r r r )�_hashlibr r+ �getattr�AttributeErrorr' )r( �fr r r �__get_openssl_constructor{ s r0 � c K s t | �|f|�S )z�new(name, data=b'', **kwargs) - Return a new hashing object using the named algorithm; optionally initialized with data (which must be a bytes-like object). )r+ )r( �data�kwargsr r r �__py_new� s r4 c K s� t j� r(| }ddddddd�j| | �} n| dkr@t| �|f|�S y:|jd d �}t j| ||d �}t j� rx| |krx|j|� |S tk r� t j� r�� t| �|�S X d S )z�new(name, data=b'') - Return a new hashing object using the named algorithm; optionally initialized with data (which must be a bytes-like object). zsha3-224zsha3-256zsha3-384zsha3-512Zshake128Zshake256)r r r r r r r r �usedforsecurityT)r5 N> r r )r, r r r+ �popr Z _set_namer' )r( r2 r3 Z orig_namer5 Zretvalr r r � __hash_new� s, r7 N)r )�scryptz code for hash %s was not found.)r r r r r r r r r r r r r r )r r r r )r1 )r1 )�__doc__Z__always_supported�setr r �__all__r, r r r& r r+ r0 r4 r7 r Z __get_hash�unionZopenssl_md_meth_namesr r8 Z __func_name�globalsr' ZloggingZ exceptionr r r r �<module>6 s\ + ' _strptime.cpython-36.opt-1.pyc 0000644 00000037135 15246273046 0012161 0 ustar 00 3 \�` � @ s� d Z ddlZddlZddlZddlmZ ddlmZ ddlmZ ddl m Z m ZmZ yddlmZ W n ek r� ddlmZ Y nX g Zdd � ZG d d � d e�ZG d d � d e�Ze� Z e� a dZ i a dd� Z dd� Z!ddd�Z"ddd�Z#d dd�Z$dS ) a� Strptime-related classes and functions.

Order of methods called matters for dependency reasons. The locale language is set at the offset and then checked again before exiting. This is to make sure that the attributes were not set with a mix of information from more than one locale. This would most likely happen when using threads where one thread calls a locale-dependent function while another thread changes the locale while the function in the other thread is still running. Proper coding would call for locks to prevent changing the locale while locale-dependent code is running. The check here is done in case someone does not think about doing this. Only other possible issue is if someone changed the timezone and did not call tz.tzset . That is an issue for the programmer, though, since changing the timezone is worthless without that call. z$locale changed during initializationz&timezone changed during initializationN) r �lang�_LocaleTime__calc_weekday�_LocaleTime__calc_month�_LocaleTime__calc_am_pm�_LocaleTime__calc_timezone�_LocaleTime__calc_date_time� ValueError�time�tzname�daylight)�selfr r r �__init__4 s zLocaleTime.__init__c C s( t |�}|r|jdd� n |jd� |S )Nr � )�list�insert�append)r �seq�frontr r r Z__padS s zLocaleTime.__padc C s4 dd� t d�D �}dd� t d�D �}|| _|| _d S )Nc S s g | ]}t j| j� �qS r )�calendarZday_abbr�lower)�.0�ir r r � <listcomp>_ s z-LocaleTime.__calc_weekday.<locals>.<listcomp>� c S s g | ]}t j| j� �qS r )r!

Each such tuple corresponds to a stack frame that is currently active (self.cur[-2]). The following are the definitions of its members. We use this external "parallel stack" to avoid contaminating the program that we are profiling. (old profiler used to write into the frames local dictionary!!) Derived classes can change the definition of some entries, as long as they leave [-2:] intact (frame and previous tuple). In case an internal error is detected, the -3 element is used as the function name. [ 0] = Time that needs to be charged to the parent frame's function. It is used so that a function call will not have to access the timing data for the parent frame. [ 1] = Total time spent in this frame's function, excluding time in subfunctions (this latter is tallied in cur[2]). [ 2] = Total time spent in subfunctions, excluding time executing the frame's function (this latter is tallied in cur[1]). [-3] = Name of the function that corresponds to this frame. [-2] = Actual frame that we correspond to (used to sync exception handling). [-1] = Our parent 6-tuple (corresponds to frame.f_back). Timing data for each function is stored as a 5-tuple in the dictionary self.timings[]. The index is always the name stored in self.cur[-3]. The following are the definitions of the members: [0] = The number of times this function was called, not counting direct or indirect recursion, [1] = Number of times this function appears on the stack, minus one [2] = Total time spent internal to this function [3] = Cumulative time that this function was present on the stack. In non-recursive functions, this is the total execution time from start to finish of each invocation of a function, including time spent in all subfunctions. [4] = A dictionary indicating for each function name, the number of times it was called by us. r Nc C s� i | _ d | _d| _d| _|d kr&| j}|| _|sHtj | _| _| j | _ nl|| _| j� }y t |�}W n" t k r� || _| j | _ Y n0X |dkr�| j | _ n| j| _ |tfdd�}|| _| j� | _| jd� d S )N� � c S s || � �S )Nr )�timer�sumr r r �get_time_timer� s z(Profile.__init__.<locals>.get_time_timerr )�timings�cur�cmd� c_func_name�bias�timeZ process_timer �get_time�trace_dispatch_i� dispatcher�len� TypeError�trace_dispatch�trace_dispatch_lr �t� simulate_call)r r r$ r- Zlengthr r r r r � s0 zProfile.__init__c C s� | j }|� }|d |d | j | j }|dkr8|j| _| j| | ||�rd|� }|d |d | _n |� }|d |d | | _d S )Nr r �c_call)r r- r$ r r# �dispatch)r �frame�event�argr r- �rr r r r+ � s zProfile.trace_dispatchc C sT | j }|� | j | j }|dkr(|j| _| j| | ||�rD|� | _n |� | | _d S )Nr/ )r r- r$ r r# r0 )r r1 r2 r3 r r- r r r r' � s zProfile.trace_dispatch_ic C s` | j }|� d | j | j }|dkr,|j| _| j| | ||�rL|� d | _n|� d | | _d S )Ng N@r/ )r r- r$ r r# r0 )r r1 r2 r3 r r- r r r �trace_dispatch_mac� s zProfile.trace_dispatch_macc C sT | j }|� | j | j }|dkr(|j| _| j| | ||�rD|� | _n |� | | _d S )Nr/ )r& r- r$ r r# r0 )r r1 r2 r3 r& r- r r r r, � s zProfile.trace_dispatch_lc C sD | j \}}}}}}||k r*|r*| j||�S ||| ||||f| _ dS )Nr )r! �trace_dispatch_return) r r1 r- �rpt�rit�ret�rfn�rframe�rcurr r r �trace_dispatch_exception� s z Profile.trace_dispatch_exceptionc C s� | j r@|j| j d k r@| j \}}}}}}t|tj�s@| j|d� |j} | j| j| j f} |dd| || j f| _ | j } | | kr�| | \} } }}}| | d |||f| | < nddddi f| | < dS )Nr r r ���) r! �f_back� isinstancer � fake_framer6 �f_code� co_filename�co_firstlineno�co_namer )r r1 r- r7 r8 r9 r: r; r< Zfcode�fnr �cc�ns�tt�ct�callersr r r �trace_dispatch_call s zProfile.trace_dispatch_callc C sn dd| j f}|dd||| jf| _| j}||krX|| \}}}}} ||d ||| f||< nddddi f||< dS )Nr r r )r# r! r ) r r1 r- rF r rG rH rI rJ rK r r r �trace_dispatch_c_call s z Profile.trace_dispatch_c_callc C s� || j d k r | j| j d d� | j \}}}}}}|| }|| }|\} } } } } }| | | | | | | |f| _ | j}|| \}}}}}|s�|| }|d }| |kr�|| d || < nd|| < ||d || ||f||< dS )Nr r r r> r> )r! r6 r )r r1 r- r7 r8 r9 r: r< Z frame_totalZpptZpitZpetZpfn�pframeZpcurr rG rH rI rJ rK r r r r6 # s" z Profile.trace_dispatch_return)�callZ exception�returnr/ Z c_exceptionZc_returnc C s" | j d rd S || _| j|� d S )Nr ���)r! r" r. )r r" r r r �set_cmdY s zProfile.set_cmdc @ s e Zd Zdd� Zdd� ZdS )zProfile.fake_codec C s || _ || _|| _d| _d S )Nr )rC �co_linerE rD )r r �line�namer r r r _ s zProfile.fake_code.__init__c C s t | j| j| jf�S )N)�reprrC rS rE )r r r r �__repr__e s zProfile.fake_code.__repr__N)r r r r rW r r r r � fake_code^ s rX c @ s e Zd Zdd� ZdS )zProfile.fake_framec C s || _ || _d S )N)rB r?

An audio file consists of a header followed by the data. The structure of the header is as follows. +---------------+ | magic word | +---------------+ | header size | +---------------+ | data size | +---------------+ | encoding | +---------------+ | sample rate | +---------------+ | # of channels | +---------------+ | info | | | +---------------+ The magic word consists of the 4 characters '.snd'. Apart from the info field, all header fields are 4 bytes in size. They are all 32-bit unsigned integers encoded in big-endian byte order. The header size really gives the start of the data. The data size is the physical size of the data. From the other parameters the number of frames can be calculated. The encoding gives the way in which audio samples are encoded. Possible values are listed below. The info field currently consists of an ASCII string giving a human-readable description of the audio file. The info field is padded with NUL bytes to the header size. Usage. Reading audio files: f = sunau.open(file, 'r') where file is either the name of a file or an open file pointer. The open file pointer must have methods read(), seek(), and close(). When the setpos() and rewind() methods are not used, the seek() method is not necessary. This returns an instance of a class with the following public methods: getnchannels() -- returns number of audio channels (1 for mono, 2 for stereo) getsampwidth() -- returns sample width in bytes getframerate() -- returns sampling frequency getnframes() -- returns number of audio frames getcomptype() -- returns compression type ('NONE' or 'ULAW') getcompname() -- returns human-readable version of compression type ('not compressed' matches 'NONE') getparams() -- returns a namedtuple consisting of all of the above in the above order getmarkers() -- returns None (for compatibility with the aifc module) getmark(id) -- raises an error since the mark does not exist (for compatibility with the aifc module) readframes(n) -- returns at most n frames of audio rewind() -- rewind to the beginning of the audio stream setpos(pos) -- seek to the specified position tell() -- return the current position close() -- close the instance (make it unusable) The position returned by tell() and the position given to setpos() are compatible and have nothing to do with the actual position in the file. The close() method is called automatically when the class instance is destroyed. Writing audio files: f = sunau.open(file, 'w') where file is either the name of a file or an open file pointer. The open file pointer must have methods write(), tell(), seek(), and close(). This returns an instance of a class with the following public methods: setnchannels(n) -- set the number of channels setsampwidth(n) -- set the sample width setframerate(n) -- set the frame rate setnframes(n) -- set the number of frames setcomptype(type, name) -- set the compression type and the human-readable compression type setparams(tuple)-- set all parameters at once tell() -- return current position in output file writeframesraw(data) -- write audio frames without pathing up the file header writeframes(data) -- write audio frames and patch up the file header close() -- patch up the file header and close the output file You should set the parameters before the first writeframesraw or writeframes. The total number of frames does not need to be set, but when it is set to the correct value, the header does not have to be patched up. It is best to first set all parameters, perhaps possibly the compression type, and then write audio frames using writeframesraw. When all frames have been written, either call writeframes(b'') or close() to patch up the sizes in the header. The close() method is called automatically when the class instance is destroyed. � )� namedtuple� _sunau_paramsz7nchannels sampwidth framerate nframes comptype compnameidns.� � � � � � � � � � � � l �� c @ s e Zd ZdS )�ErrorN)�__name__� __module__� __qualname__� r r � /usr/lib64/python3.6/sunau.pyr � s r c C s< d}x2t d�D ]&}| jd�}|s$t�|d t|� }qW |S )Nr r r � )�range�read�EOFError�ord)�file�x�iZbyter r r � _read_u32� s r c C sJ g }x2t d�D ]&}t|d�\}}|jdt|�� |}qW | jt|�� d S )Nr r r )r �divmod�insert�int�write�bytes)r r �datar �d�mr r r � _write_u32� s r' c @ s� e Zd Zdd� Zdd� Zdd� Zdd� Zd d � Zd d � Zd d� Z dd� Z dd� Z dd� Z dd� Z dd� Zdd� Zdd � Zd d � Zd d � Zd!d"� Zd#d$� Zd%d&� Zd'd(� Zd)S )*�Au_readc C s@ t |�t d�kr,dd l}|j|d�}d| _nd| _| j|� d S )N� r �rbTF)�type�builtins�open�_opened�initfp)�self�fr, r r r �__init__� s zAu_read.__init__c C s | j r| j� d S )N)�_file�close)r0 r r r �__del__� s zAu_read.__del__c C s | S )Nr )r0 r r r � __enter__� s zAu_read.__enter__c G s | j � d S )N)r4 )r0 �argsr r r �__exit__� s zAu_read.__exit__c C s� || _ d| _tt|��}|tkr(td��tt|��| _| jdk rHtd��| jdkrZtd��t|�| _| jtkrzt| j�| _tt|��| _ | j t kr�td��| j t t fkr�d| _ d | _nj| j tkr�d | _| _ nR| j tkr�d | _| _ n:| j tkr�d | _| _ n"| j tk�rd | _| _ ntd ��tt|��| _tt|��| _| j| j | _| jdk�r~|j| jd �| _| jjd �\| _}}nd| _y|j� | _W n ttfk �r� d | _Y nX d S )Nr zbad magic numberr zheader size too small�d z header size ridiculously largez encoding not (yet) supportedr r r r zunknown encoding� � ) r3 � _soundposr! r �AUDIO_FILE_MAGICr Z _hdr_size� _data_size�AUDIO_UNKNOWN_SIZE� _encoding�_simple_encodings�AUDIO_FILE_ENCODING_MULAW_8�AUDIO_FILE_ENCODING_ALAW_8� _sampwidth� _framesize� AUDIO_FILE_ENCODING_LINEAR_8� AUDIO_FILE_ENCODING_LINEAR_16� AUDIO_FILE_ENCODING_LINEAR_24� AUDIO_FILE_ENCODING_LINEAR_32� _framerate� _nchannelsr �_info� partition�tell� _data_pos�AttributeError�OSError)r0 r �magic�_r r r r/ � sP zAu_read.initfpc C s | j S )N)r3 )r0 r r r �getfp� s z Au_read.getfpc C s | j S )N)rK )r0 r r r � getnchannels� s zAu_read.getnchannelsc C s | j S )N)rD )r0 r r r � getsampwidth� s zAu_read.getsampwidthc C s | j S )N)rJ )r0 r r r � getframerate� s zAu_read.getframeratec C s( | j tkrtS | jtkr$| j | j S dS )Nr )r> r?

For the sake of comparison, non-existing elements are considered to be infinite. The interesting property of a heap is that a[0] is always its smallest element. The strange invariant above is meant to be an efficient memory representation for a tournament. The numbers below are `k', not a[k]: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 In the tree above, each cell `k' is topping `2*k+1' and `2*k+2'. In a usual binary tournament we see in sports, each cell is the winner over the two cells it tops, and we can trace the winner down the tree to see all opponents s/he had. However, in many computer applications of such tournaments, we do not need to trace the history of a winner. To be more memory efficient, when a winner is promoted, we try to replace it by something else at a lower level, and the rule becomes that a cell and the two cells it tops contain three different items, but the top cell "wins" over the two topped cells. If this heap invariant is protected at all time, index 0 is clearly the overall winner. The simplest algorithmic way to remove it and find the "next" winner is to move some loser (let's say cell 30 in the diagram above) into the 0 position, and then percolate this new 0 down the tree, exchanging values, until the invariant is re-established. This is clearly logarithmic on the total number of items in the tree. By iterating over all items, you get an O(n ln n) sort. A nice feature of this sort is that you can efficiently insert new items while the sort is going on, provided that the inserted items are not "better" than the last 0'th element you extracted. This is especially useful in simulation contexts, where the tree holds all incoming events, and the "win" condition means the smallest scheduled time. When an event schedule other events for execution, they are scheduled into the future, so they can easily go into the heap. So, a heap is a good structure for implementing schedulers (this is what I used for my MIDI sequencer :-). Various structures for implementing schedulers have been extensively studied, and heaps are good for this, as they are reasonably speedy, the speed is almost constant, and the worst case is not much different than the average case. However, there are other representations which are more efficient overall, yet the worst cases might be terrible. Heaps are also very useful in big disk sorts. You most probably all know that a big sort implies producing "runs" (which are pre-sorted sequences, which size is usually related to the amount of CPU memory), followed by a merging passes for these runs, which merging is often very cleverly organised[1]. It is very important that the initial sort produces the longest runs possible. Tournaments are a good way to that. If, using all the memory available to hold a tournament, you replace and percolate items that happen to fit the current run, you'll produce runs which are twice the size of the memory for random input, and much better for input fuzzily ordered. Moreover, if you output the 0'th item on disk and get an input which may not fit in the current tournament (because the value "wins" over the last output value), it cannot fit in the heap, so the size of the heap decreases. The freed memory could be cleverly reused immediately for progressively building a second heap, which grows at exactly the same rate the first heap is melting. When the first heap completely vanishes, you switch heaps and start a new run. Clever and quite effective! In a word, heaps are useful memory structures to know. I use them in a few applications, and I think it is good to keep a `heap' module around. :-) -------------------- [1] The disk balancing algorithms which are current, nowadays, are more annoying than clever, and this is a consequence of the seeking capabilities of the disks. On devices which cannot seek, like big tape drives, the story was quite different, and one had to be very clever to ensure (far in advance) that each tape movement will be the most effective possible (that is, will best participate at "progressing" the merge). Some tapes were even able to read backwards, and this was also used to avoid the rewinding time. Believe me, real good tape sorts were quite spectacular to watch! From all times, sorting has always been a Great Art! :-) �heappush�heappop�heapify� heapreplace�merge�nlargest� nsmallest� heappushpopc C s" | j |� t| dt| �d � d S )N� � )�append� _siftdown�len)�heap�item� r � /usr/lib64/python3.6/heapq.pyr � s c C s. | j � }| r*| d }|| d< t| d� |S |S )Nr )�pop�_siftup)r �lastelt� returnitemr r r r � s c C s | d }|| d< t | d� |S )Nr )r )r r r r r r r � s c C s0 | r,| d |k r,| d | }| d< t | d� |S )Nr )r )r r r r r r � s c C s0 t | �}x"tt|d ��D ]}t| |� qW d S )N� )r �reversed�ranger )�x�n�ir r r r � s c C s. | j � }| r*| d }|| d< t| d� |S |S )Nr )r � _siftup_max)r r r r r r � _heappop_max� s r c C s | d }|| d< t | d� |S )Nr )r )r r r r r r �_heapreplace_max� s r c C s0 t | �}x"tt|d ��D ]}t| |� qW d S )Nr )r r r r )r r r r r r � _heapify_max� s r c C sN | | }x8||kr@|d d? }| | }||k r<|| |< |}q P q W || |< d S )Nr r )r �startpos�pos�newitem� parentpos�parentr r r r � s r c C s� t | �}|}| | }d| d }xN||k rn|d }||k rP| | | | k rP|}| | | |< |}d| d }q"W || |< t| ||� d S )Nr r )r r )r r! �endposr r" �childpos�rightposr r r r s r c C sN | | }x8||kr@|d d? }| | }||k r<|| |< |}q P q W || |< d S )Nr r )r r r! r" r# r$ r r r � _siftdown_max s r( c C s� t | �}|}| | }d| d }xN||k rn|d }||k rP| | | | k rP|}| | | |< |}d| d }q"W || |< t| ||� d S )Nr r )r r( )r r! r% r r" r& r' r r r r % s r NF)�key�reversec g s4 g }|j }|r t}t}t}d}nt}t}t}d}| d k�r"xNttt |��D ]<\} } y | j } || � | | | g� W qJ t k r� Y qJX qJW ||� xdt |�dkr�y6x0|d \} } } } | V | � | d< ||| � q�W W q� t k r� ||� Y q�X q�W |�r |d \} } } | V | j E d H d S x\ttt |��D ]J\} } y(| j } | � } || | �| | | | g� W n t k �rx Y nX �q2W ||� x~t |�dk�ryJxD|d \}} } } } | V | � } | | �| d< | | d< ||| � �q�W W n t k �r ||� Y nX �q�W |�r0|d \}} } } | V | j E d H d S )Nr r r ���)r r r r r r r � enumerate�map�iter�__next__� StopIterationr �__self__)r) r* � iterables�h�h_append�_heapify�_heappop� _heapreplace� direction�order�it�next�value�s� key_valuer r r r : sp c s� | dkrLt |�}t� }� d kr,t||d�}nt||� d�}||krFg S |gS y t|�}W n ttfk rp Y n X | |kr�t|� d�d | � S � d k�r*t |�}dd� tt| �|�D �}|s�|S t |� |d d }| }t } x6|D ].} | |k r�| || |f� |d d }|d7 }q�W |j � dd� |D �S t |�}� fd d�tt| �|�D �}|�sX|S t |� |d d }| }t } xD|D ]<} � | �} | |k �rz| || || f� |d d }|d7 }�qzW |j � d d� |D �S ) Nr )�default)r? r) )r) c S s g | ]\}}||f�qS r r )�.0r �elemr r r � <listcomp>� s z nsmallest.<locals>.<listcomp>r c S s g | ] }|d �qS )r r )r@ �rr r r rB � s c s g | ]\}}� |�||f�qS r r )r@ r rA )r) r r rB � s c S s g | ] }|d �qS )r r )r@ rC r r r rB s ) r. �object�minr � TypeError�AttributeError�sorted�zipr r r �sort) r �iterabler) r: �sentinel�result�size�topr9 r7 rA �kr )r) r r � sZ c s� | dkrLt |�}t� }� d kr,t||d�}nt||� d�}||krFg S |gS y t|�}W n ttfk rp Y n X | |kr�t|� dd�d | � S � d k�r8t |�}dd� ttd| d �|�D �}|s�|S t |� |d d }| }t } x6|D ].} || k r�| || |f� |d d }|d8 }q�W |j dd � d d� |D �S t |�}� fd d�ttd| d�|�D �}|�sl|S t |� |d d }| }t } xD|D ]<} � | �} || k �r�| || || f� |d d }|d8 }�q�W |j dd � d d� |D �S )Nr )r? )r? r) T)r) r* c S s g | ]\}}||f�qS r r )r@ r rA r r r rB ( s z nlargest.<locals>.<listcomp>r )r* c S s g | ] }|d �qS )r r )r@ rC r r r rB 5 s c s g | ]\}}� |�||f�qS r r )r@ r rA )r) r r rB 9 s c S s g | ] }|d �qS )r r )r@ rC r r r rB G s r+ r+ ) r. rD �maxr rF rG rH rI r r r rJ ) r rK r) r: rL rM rN rO r9 r7 rA rP r )r) r r sZ " r )�*)r )r )r �__main__)N)N)� __about__�__all__r r r r r r r r r r r( r r r r �_heapq� ImportError�__name__Zdoctest�printZtestmodr r r r �<module>} sJ 5 ? > dummy_threading.cpython-36.pyc 0000644 00000002120 15246273046 0012356 0 ustar 00 3 \� � @ s d Z ddlmZ ddlZdZdZdZz�dekr:ed ZdZed ed< dekr`ed Z dZed= d ekrzed Z dZed = ddl Z ed ed < ed= ed ed < ed = dd l T dd l m Z W der�e ed< [ [er�e ed < [ [er�eed< [ned= [[[X dS )aa Faux ``threading`` version using ``dummy_thread`` instead of ``thread``.

Opcodes that operate on a variable number of objects generally don't embed the count of objects in the opcode, or pull it off the stack. Instead the MARK opcode is used to push a special marker object on the stack, and then some other opcodes grab all the objects from the top of the stack down to (but not including) the topmost marker object. � stackslicea� An object representing a contiguous slice of the stack. This is used in conjunction with markobject, to represent all of the stack following the topmost markobject. For example, the POP_MARK opcode changes the stack from [..., markobject, stackslice] to [...] No matter how many object are on the stack after the topmost markobject, POP_MARK gets rid of all of them (including the topmost markobject too). c @ s e Zd Zd Zdd � Zd S ) � OpcodeInfor �code�arg� stack_before� stack_after�protor c C s� t |t�st�|| _t |t�s"t�t|�dks2t�|| _|d ksNt |t�sNt�|| _t |t�sbt�x|D ]}t |t �sht�qhW || _ t |t�s�t�x|D ]}t |t �s�t�q�W || _ t |t �r�d| ko�t jkn s�t�|| _t |t�s�t�|| _d S )Nr r )r r r r r' ry r rz rr rj r{ r| r �pickleZHIGHEST_PROTOCOLr} r ) r r ry rz r{ r| r} r �xr r r r T s& (zOpcodeInfo.__init__N)r ry rz r{ r| r} r )r r r r r r r r r rx 5 s rx ZINT�Ia� Push an integer or bool. The argument is a newline-terminated decimal literal string. The intent may have been that this always fit in a short Python int, but INT can be generated in pickles written on a 64-bit box that require a Python long on a 32-bit box. The difference between this and LONG then is that INT skips a trailing 'L', and produces a short int whenever possible. Another difference is due to that, when bool was introduced as a distinct type in 2.3, builtin names True and False were also added to 2.2.2, mapping to ints 1 and 0. For compatibility in both directions, True gets pickled as INT + "I01\n", and False as INT + "I00\n". Leading zeroes are never produced for a genuine integer. The 2.3 (and later) unpicklers special-case these and return bool instead; earlier unpicklers ignore the leading "0" and return the int. )r ry rz r{ r| r} r ZBININT�Ja1 Push a four-byte signed integer. This handles the full range of Python (short) integers on a 32-bit box, directly as binary bytes (1 for the opcode and 4 for the integer). If the integer is non-negative and fits in 1 or 2 bytes, pickling via BININT1 or BININT2 saves space. ZBININT1�Kz�Push a one-byte unsigned integer. This is a space optimization for pickling very small non-negative ints, in range(256). ZBININT2�Mz�Push a two-byte unsigned integer. This is a space optimization for pickling small positive ints, in range(256, 2**16). Integers in range(256) can also be pickled via BININT2, but BININT1 instead saves a byte. ZLONG�La� Push a long integer. The same as INT, except that the literal ends with 'L', and always unpickles to a Python long. There doesn't seem a real purpose to the trailing 'L'. Note that LONG takes time quadratic in the number of digits when unpickling (this is simply due to the nature of decimal->binary conversion). Proto 2 added linear-time (in C; still quadratic-time in Python) LONG1 and LONG4 opcodes. ZLONG1� z|Long integer using one-byte length. A more efficient encoding of a Python long; the long1 encoding says it all.ZLONG4� z~Long integer using found-byte length. A more efficient encoding of a Python long; the long4 encoding says it all.�STRING�Sa� Push a Python string object. The argument is a repr-style string, with bracketing quote characters, and perhaps embedded escapes. The argument extends until the next newline character. These are usually decoded into a str instance using the encoding given to the Unpickler constructor. or the default, 'ASCII'. If the encoding given was 'bytes' however, they will be decoded as bytes object instead. Z BINSTRING�Ta� Push a Python string object. There are two arguments: the first is a 4-byte little-endian signed int giving the number of bytes in the string, and the second is that many bytes, which are taken literally as the string content. These are usually decoded into a str instance using the encoding given to the Unpickler constructor. or the default, 'ASCII'. If the encoding given was 'bytes' however, they will be decoded as bytes object instead. ZSHORT_BINSTRING�Ua� Push a Python string object. There are two arguments: the first is a 1-byte unsigned int giving the number of bytes in the string, and the second is that many bytes, which are taken literally as the string content. These are usually decoded into a str instance using the encoding given to the Unpickler constructor. or the default, 'ASCII'. If the encoding given was 'bytes' however, they will be decoded as bytes object instead. ZBINBYTES�Bz�Push a Python bytes object. There are two arguments: the first is a 4-byte little-endian unsigned int giving the number of bytes, and the second is that many bytes, which are taken literally as the bytes content. ZSHORT_BINBYTES�Cz�Push a Python bytes object. There are two arguments: the first is a 1-byte unsigned int giving the number of bytes, and the second is that many bytes, which are taken literally as the string content. Z BINBYTES8� z�Push a Python bytes object. There are two arguments: the first is an 8-byte unsigned int giving the number of bytes in the string, and the second is that many bytes, which are taken literally as the string content. ZNONE�NzPush None on the stack.ZNEWTRUE� zPush True onto the stack.ZNEWFALSE� zPush False onto the stack.�UNICODE�Vz�Push a Python Unicode string object. The argument is a raw-unicode-escape encoding of a Unicode string, and so may contain embedded escape sequences. The argument extends until the next newline character. ZSHORT_BINUNICODE� a Push a Python Unicode string object. There are two arguments: the first is a 1-byte little-endian signed int giving the number of bytes in the string. The second is that many bytes, and is the UTF-8 encoding of the Unicode string. Z BINUNICODE�Xa Push a Python Unicode string object. There are two arguments: the first is a 4-byte little-endian unsigned int giving the number of bytes in the string. The second is that many bytes, and is the UTF-8 encoding of the Unicode string. Z BINUNICODE8� a Push a Python Unicode string object. There are two arguments: the first is an 8-byte little-endian signed int giving the number of bytes in the string. The second is that many bytes, and is the UTF-8 encoding of the Unicode string. ZFLOAT�Fa� Newline-terminated decimal float literal. The argument is repr(a_float), and in general requires 17 significant digits for roundtrip conversion to be an identity (this is so for IEEE-754 double precision values, which is what Python float maps to on most boxes). In general, FLOAT cannot be used to transport infinities, NaNs, or minus zero across boxes (or even on a single box, if the platform C library can't read the strings it produces for such things -- Windows is like that), but may do less damage than BINFLOAT on boxes with greater precision or dynamic range than IEEE-754 double. ZBINFLOAT�Ga� Float stored in binary form, with 8 bytes of data. This generally requires less than half the space of FLOAT encoding. In general, BINFLOAT cannot be used to transport infinities, NaNs, or minus zero, raises an exception if the exponent exceeds the range of an IEEE-754 double, and retains no more than 53 bits of precision (if there are more than that, "add a half and chop" rounding is used to cut it back to 53 significant bits). Z EMPTY_LIST�]zPush an empty list.ZAPPEND�az�Append an object to a list. Stack before: ... pylist anyobject Stack after: ... pylist+[anyobject] although pylist is really extended in-place. ZAPPENDS�ez�Extend a list by a slice of stack objects. Stack before: ... pylist markobject stackslice Stack after: ... pylist+stackslice although pylist is really extended in-place. ZLIST�las Build a list out of the topmost stack slice, after markobject. All the stack entries following the topmost markobject are placed into a single Python list, which single list object replaces all of the stack from the topmost markobject onward. For example, Stack before: ... markobject 1 2 3 'abc' Stack after: ... [1, 2, 3, 'abc'] Z EMPTY_TUPLE�)zPush an empty tuple.ZTUPLE�tav Build a tuple out of the topmost stack slice, after markobject. All the stack entries following the topmost markobject are placed into a single Python tuple, which single tuple object replaces all of the stack from the topmost markobject onward. For example, Stack before: ... markobject 1 2 3 'abc' Stack after: ... (1, 2, 3, 'abc') ZTUPLE1� z�Build a one-tuple out of the topmost item on the stack. This code pops one value off the stack and pushes a tuple of length 1 whose one item is that value back onto it. In other words: stack[-1] = tuple(stack[-1:]) ZTUPLE2� a Build a two-tuple out of the top two items on the stack. This code pops two values off the stack and pushes a tuple of length 2 whose items are those values back onto it. In other words: stack[-2:] = [tuple(stack[-2:])] ZTUPLE3� a Build a three-tuple out of the top three items on the stack. This code pops three values off the stack and pushes a tuple of length 3 whose items are those values back onto it. In other words: stack[-3:] = [tuple(stack[-3:])] Z EMPTY_DICT�}zPush an empty dict.ZDICT�da� Build a dict out of the topmost stack slice, after markobject. All the stack entries following the topmost markobject are placed into a single Python dict, which single dict object replaces all of the stack from the topmost markobject onward. The stack slice alternates key, value, key, value, .... For example, Stack before: ... markobject 1 2 3 'abc' Stack after: ... {1: 2, 3: 'abc'} ZSETITEMrZ z�Add a key+value pair to an existing dict. Stack before: ... pydict key value Stack after: ... pydict where pydict has been modified via pydict[key] = value. ZSETITEMS�ua\ Add an arbitrary number of key+value pairs to an existing dict. The slice of the stack following the topmost markobject is taken as an alternating sequence of keys and values, added to the dict immediately under the topmost markobject. Everything at and after the topmost markobject is popped, leaving the mutated dict at the top of the stack. Stack before: ... pydict markobject key_1 value_1 ... key_n value_n Stack after: ... pydict where pydict has been modified via pydict[key_i] = value_i for i in 1, 2, ..., n, and in that order. Z EMPTY_SET� zPush an empty set.ZADDITEMS� a$ Add an arbitrary number of items to an existing set. The slice of the stack following the topmost markobject is taken as a sequence of items, added to the set immediately under the topmost markobject. Everything at and after the topmost markobject is popped, leaving the mutated set at the top of the stack. Stack before: ... pyset markobject item_1 ... item_n Stack after: ... pyset where pyset has been modified via pyset.add(item_i) = item_i for i in 1, 2, ..., n, and in that order. Z FROZENSET� az Build a frozenset out of the topmost slice, after markobject. All the stack entries following the topmost markobject are placed into a single Python frozenset, which single frozenset object replaces all of the stack from the topmost markobject onward. For example, Stack before: ... markobject 1 2 3 Stack after: ... frozenset({1, 2, 3}) �POP�0z<Discard the top stack item, shrinking the stack by one item.ZDUP�2z=Push the top stack item onto the stack again, duplicating it.�MARK�(z�Push markobject onto the stack. markobject is a unique object, used by other opcodes to identify a region of the stack containing a variable number of objects for them to work on. See markobject.doc for more detail. ZPOP_MARK�1a Pop all the stack objects at and above the topmost markobject. When an opcode using a variable number of stack objects is done, POP_MARK is used to remove those objects, and to remove the markobject that delimited their starting position on the stack. �GET�gz�Read an object from the memo and push it on the stack. The index of the memo object to push is given by the newline-terminated decimal string following. BINGET and LONG_BINGET are space-optimized versions. �BINGET�hz�Read an object from the memo and push it on the stack. The index of the memo object to push is given by the 1-byte unsigned integer following. � LONG_BINGET�jz�Read an object from the memo and push it on the stack. The index of the memo object to push is given by the 4-byte unsigned little-endian integer following. �PUT�pz�Store the stack top into the memo. The stack is not popped. The index of the memo location to write into is given by the newline- terminated decimal string following. BINPUT and LONG_BINPUT are space-optimized versions. �BINPUTr> z�Store the stack top into the memo. The stack is not popped. The index of the memo location to write into is given by the 1-byte unsigned integer following. � LONG_BINPUT�rz�Store the stack top into the memo. The stack is not popped. The index of the memo location to write into is given by the 4-byte unsigned little-endian integer following. �MEMOIZE� z�Store the stack top into the memo. The stack is not popped. The index of the memo location to write is the number of elements currently present in the memo. ZEXT1� a� Extension code. This code and the similar EXT2 and EXT4 allow using a registry of popular objects that are pickled by name, typically classes. It is envisioned that through a global negotiation and registration process, third parties can set up a mapping between ints and object names. In order to guarantee pickle interchangeability, the extension code registry ought to be global, although a range of codes may be reserved for private use. EXT1 has a 1-byte integer argument. This is used to index into the extension registry, and the object at that index is pushed on the stack. ZEXT2� zNExtension code. See EXT1. EXT2 has a two-byte integer argument. ZEXT4� zOExtension code. See EXT1. EXT4 has a four-byte integer argument. ZGLOBAL�ca� Push a global object (module.attr) on the stack. Two newline-terminated strings follow the GLOBAL opcode. The first is taken as a module name, and the second as a class name. The class object module.class is pushed on the stack. More accurately, the object returned by self.find_class(module, class) is pushed on the stack, so unpickling subclasses can override this form of lookup. Z STACK_GLOBAL� z7Push a global object (module.attr) on the stack. ZREDUCE�RaL Push an object built from a callable and an argument tuple. The opcode is named to remind of the __reduce__() method. Stack before: ... callable pytuple Stack after: ... callable(*pytuple) The callable and the argument tuple are the first two items returned by a __reduce__ method. Applying the callable to the argtuple is supposed to reproduce the original object, or at least get it started. If the __reduce__ method returns a 3-tuple, the last component is an argument to be passed to the object's __setstate__, and then the REDUCE opcode is followed by code to create setstate's argument, and then a BUILD opcode to apply __setstate__ to that argument. If not isinstance(callable, type), REDUCE complains unless the callable has been registered with the copyreg module's safe_constructors dict, or the callable has a magic '__safe_for_unpickling__' attribute with a true value. I'm not sure why it does this, but I've sure seen this complaint often enough when I didn't want to <wink>. ZBUILD�ba� Finish building an object, via __setstate__ or dict update. Stack before: ... anyobject argument Stack after: ... anyobject where anyobject may have been mutated, as follows: If the object has a __setstate__ method, anyobject.__setstate__(argument) is called. Else the argument must be a dict, the object must have a __dict__, and the object is updated via anyobject.__dict__.update(argument) ZINST�iaq Build a class instance. This is the protocol 0 version of protocol 1's OBJ opcode. INST is followed by two newline-terminated strings, giving a module and class name, just as for the GLOBAL opcode (and see GLOBAL for more details about that). self.find_class(module, name) is used to get a class object. In addition, all the objects on the stack following the topmost markobject are gathered into a tuple and popped (along with the topmost markobject), just as for the TUPLE opcode. Now it gets complicated. If all of these are true: + The argtuple is empty (markobject was at the top of the stack at the start). + The class object does not have a __getinitargs__ attribute. then we want to create an old-style class instance without invoking its __init__() method (pickle has waffled on this over the years; not calling __init__() is current wisdom). In this case, an instance of an old-style dummy class is created, and then we try to rebind its __class__ attribute to the desired class object. If this succeeds, the new instance object is pushed on the stack, and we're done. Else (the argtuple is not empty, it's not an old-style class object, or the class object does have a __getinitargs__ attribute), the code first insists that the class object have a __safe_for_unpickling__ attribute. Unlike as for the __safe_for_unpickling__ check in REDUCE, it doesn't matter whether this attribute has a true or false value, it only matters whether it exists (XXX this is a bug). If __safe_for_unpickling__ doesn't exist, UnpicklingError is raised. Else (the class object does have a __safe_for_unpickling__ attr), the class object obtained from INST's arguments is applied to the argtuple obtained from the stack, and the resulting instance object is pushed on the stack. NOTE: checks for __safe_for_unpickling__ went away in Python 2.3. NOTE: the distinction between old-style and new-style classes does not make sense in Python 3. ZOBJ�oa� Build a class instance. This is the protocol 1 version of protocol 0's INST opcode, and is very much like it. The major difference is that the class object is taken off the stack, allowing it to be retrieved from the memo repeatedly if several instances of the same class are created. This can be much more efficient (in both time and space) than repeatedly embedding the module and class names in INST opcodes. Unlike INST, OBJ takes no arguments from the opcode stream. Instead the class object is taken off the stack, immediately above the topmost markobject: Stack before: ... markobject classobject stackslice Stack after: ... new_instance_object As for INST, the remainder of the stack above the markobject is gathered into an argument tuple, and then the logic seems identical, except that no __safe_for_unpickling__ check is done (XXX this is a bug). See INST for the gory details. NOTE: In Python 2.3, INST and OBJ are identical except for how they get the class object. That was always the intent; the implementations had diverged for accidental reasons. ZNEWOBJ� aL Build an object instance. The stack before should be thought of as containing a class object followed by an argument tuple (the tuple being the stack top). Call these cls and args. They are popped off the stack, and the value returned by cls.__new__(cls, *args) is pushed back onto the stack. Z NEWOBJ_EX� au Build an object instance. The stack before should be thought of as containing a class object followed by an argument tuple and by a keyword argument dict (the dict being the stack top). Call these cls and args. They are popped off the stack, and the value returned by cls.__new__(cls, *args, *kwargs) is pushed back onto the stack. �PROTO� z�Protocol version indicator. For protocol 2 and above, a pickle must start with this opcode. The argument is the protocol version, an int in range(2, 256). �STOP�.z�Stop the unpickling machine. Every pickle ends with this opcode. The object at the top of the stack is popped, and that's the result of unpickling. The stack should be empty then. �FRAME� z�Indicate the beginning of a new frame. The unpickler may use this opcode to safely prefetch data from its underlying stream. ZPERSID�Pa Push an object identified by a persistent ID. The pickle module doesn't define what a persistent ID means. PERSID's argument is a newline-terminated str-style (no embedded escapes, no bracketing quote characters) string, which *is* "the persistent ID". The unpickler passes this string to self.persistent_load(). Whatever object that returns is pushed on the stack. There is no implementation of persistent_load() in Python's unpickler: it must be supplied by an unpickler subclass. Z BINPERSID�QaX Push an object identified by a persistent ID. Like PERSID, except the persistent ID is popped off the stack (instead of being a string embedded in the opcode bytestream). The persistent ID is passed to self.persistent_load(), and whatever object that returns is pushed on the stack.

'pickle' is a file-like object, or string, containing the pickle. Each opcode in the pickle is generated, from the current pickle position, stopping after a STOP opcode is delivered. A triple is generated for each opcode: opcode, arg, pos opcode is an OpcodeInfo record, describing the current opcode. If the opcode has an argument embedded in the pickle, arg is its decoded value, as a Python object. If the opcode doesn't have an argument, arg is None. If the pickle has a tell() method, pos was the value of pickle.tell() before reading the current opcode. If the pickle is a bytes object, it's wrapped in a BytesIO object, and the latter's tell() result is used. Else (the pickle doesn't have a tell(), and it's not obvious how to query its current position) pos is None. )r� )r~ r r r r � s c C s� d}d}t � }i }g }d}d}x�t| dd�D ]�\}} } } d|jkr\|j| � |j|| f� q,|jdkr�t|�} |j| � |j|| f� q,d|jkr�q,d|jkr�|j|kr�|j}d || < |j|| f� q,|jd k�r| |kr�| }| dkr�| | | � }n|j| | f� q,|j| | f� q,W ~tj� } | j |� t j | |�}|d k�rJ|j j � d} x�|D ]x\}} ||k�r�| |k�rt�qT|j| �}| || < | d 7 } n&||k�r�|j|| �}n | || � }|j j� |j |� �qTW |j j� | j� S ) z7Optimize a pickle string by removing unused PUT opcodesr� r� r r� T)r� r� r� Nr� r r )rt r� r �addr� r' r} r� r� �writer~ Z_PicklerZframerZ start_framing�putr� Z commit_frameZ end_framing�getvalue)r� r� r� ZoldidsZnewids�opcodesr} Z protoheaderr� rz r� Zend_pos�idx�outZpickler�opr$ r r r r � sd c C st g }|dkri }d }g }d| }d} |} �x$t | �D �]\} } } | dk rZtd| d|d� dt| j�dd � |t|� | jf }t|| j�}| j}| j }t|�}d}t |ks�| jdko�|o�|d! t k�r|t |ks�t �t |kr�|d" t ks�t �|�rt|j � }|dk�r d}nd | }x |d# t k �r.|j � �qW |j � y|jt �}W n* tk �rp | jdk�sht �d }Y nX nd } }| jd$k�r�| jdk�r�t|�}d| }n| dk �s�t �| }||k�r�d| } n,|�s�d} n |d% t k�r�d} n |d& ||< n<| jd'k�r6| |k�r.t|�dk�s"t �|| g}nd| } | dk �sF|�r�|ddt| j� 7 }| dk �rv|dt| � 7 }|�r�|d| 7 }|�r�|d| t|� 7 }t|�} | dk�r�|} |d| jjdd�d 7 }t||d� | �r�t| ��t|�|k �rtd |t|�f ��|�r || d�= t |k�rBt |k�s8t �|j| � |j|� q4W td ||d� |�rptd | ��dS )(aK Produce a symbolic disassembly of a pickle. 'pickle' is a file-like object, or string, containing a (at least one) pickle. The pickle is disassembled from the current position, through the first STOP opcode encountered. Optional arg 'out' is a file-like object to which the disassembly is printed. It defaults to sys.stdout. Optional arg 'memo' is a Python dict, used as the pickle's memo. It may be mutated by dis(), if the pickle contains PUT or BINPUT opcodes. Passing the same memo object to another dis() call then allows disassembly to proceed across multiple pickles that were all created by the same pickler with the same memo. Ordinarily you don't need to worry about this. Optional arg 'indentlevel' is the number of blanks by which to indent a new MARK level. It defaults to 4. Optional arg 'annotate' if nonzero instructs dis() to add short description of the opcode on each line of disassembled output. The value given to 'annotate' must be an integer and is used as a hint for the column where annotation should start. The default value is 0, meaning no annotations. In addition to printing the disassembly, some sanity checks are made: + All embedded opcode arguments "make sense". + Explicit and implicit pop operations have enough items on the stack. + When an opcode implicitly refers to a markobject, a markobject is actually on the stack. + A memo entry isn't referenced before it's defined. + The markobject isn't stored in the memo. + A memo entry isn't redefined.

It also contains the following, for tuning the behavior: Data: knownfiles -- list of files to parse inited -- flag set when init() has been called suffix_map -- dictionary mapping suffixes to suffixes encodings_map -- dictionary mapping suffixes to encodings types_map -- dictionary mapping suffixes to types Functions: init([files]) -- parse a list of files, default knownfiles (on Windows, the default values are taken from the registry) read_mime_types(file) -- parse one file, return a dictionary or None � N� knownfiles�inited� MimeTypes� guess_type�guess_all_extensions�guess_extension�add_type�init�read_mime_types� suffix_map� encodings_map� types_map� common_typesz/etc/mime.typesz/etc/httpd/mime.typesz/etc/httpd/conf/mime.typesz/etc/apache/mime.typesz/etc/apache2/mime.typesz$/usr/local/etc/httpd/conf/mime.typesz"/usr/local/lib/netscape/mime.typesz/usr/local/etc/mime.typesFc @ sd e Zd ZdZf dfdd�Zddd�Zddd�Zdd d �Zdd d �Zdd d�Z ddd�Z ddd�Z dS )r z�MIME-types datastore.

On Unix (including Mac OSX), it starts with sys.prefix and sys.exec_prefix (if different) and appends lib/python<version>/site-packages. On other platforms (such as Windows), it tries each of the prefixes directly, as well as with lib/site-packages appended. The resulting directories, if they exist, are appended to sys.path, and also inspected for path configuration files. If a file named "pyvenv.cfg" exists one directory above sys.executable, sys.prefix and sys.exec_prefix are set to that directory and it is also checked for site-packages (sys.base_prefix and sys.base_exec_prefix will always be the "real" prefixes of the Python installation). If "pyvenv.cfg" (a bootstrap configuration file) contains the key "include-system-site-packages" set to anything other than "false" (case-insensitive), the system-level prefixes will still also be searched for site-packages; otherwise they won't. All of the resulting site-specific directories, if they exist, are appended to sys.path, and also inspected for path configuration files. A path configuration file is a file whose name has the form <package>.pth; its contents are additional directories (one per line) to be added to sys.path. Non-existing directories (or non-directories) are never added to sys.path; no directory is added to sys.path more than once. Blank lines and lines beginning with '#' are skipped. Lines starting with 'import' are executed. For example, suppose sys.prefix and sys.exec_prefix are set to /usr/local and there is a directory /usr/local/lib/python2.5/site-packages with three subdirectories, foo, bar and spam, and two path configuration files, foo.pth and bar.pth. Assume foo.pth contains the following: # foo package configuration foo bar bletch and bar.pth contains: # bar package configuration bar Then the following directories are added to sys.path, in this order: /usr/local/lib/python2.5/site-packages/bar /usr/local/lib/python2.5/site-packages/foo Note that bletch is omitted because it doesn't exist; bar precedes foo because bar.pth comes alphabetically before foo.pth; and spam is omitted because it is not mentioned in either path configuration file. The readline module is also automatically configured to enable completion for systems that support it. This can be overridden in sitecustomize, usercustomize or PYTHONSTARTUP. Starting Python in isolated mode (-I) disables automatic readline configuration. After these operations, an attempt is made to import a module named sitecustomize, which can perform arbitrary additional site-specific customizations. If this import fails with an ImportError exception, it is silently ignored. � Nc G sB t jj| � }yt jj|�}W n tk r0 Y nX |t jj|�fS )N)�os�path�join�abspath�OSError�normcase)�paths�dir� r � /usr/lib64/python3.6/site.py�makepathZ s r c C s� x�t tjj� �D ]~} tt| dd�dd�dkr.qytjj| j�| _W n t t t fk r\ Y nX ytjj| j �| _ W q t t t fk r� Y qX qW dS )zESet all module __file__ and __cached__ attributes to an absolute path� __loader__N� __module__�_frozen_importlib�_frozen_importlib_external)r r ) �set�sys�modules�values�getattrr r r �__file__�AttributeErrorr � TypeError� __cached__)�mr r r � abs_pathsc s r c C sT g } t � }x6tjD ],}t|�\}}||kr| j|� |j|� qW | tjdd�< |S )zK Remove duplicate entries from sys.path along with making them absoluteN)r r r r �append�add)�L� known_pathsr �dircaser r r �removeduppathss s r! c C sX t � } xLtjD ]B}y&tjj|�r6t|�\}}| j|� W q tk rN wY qX qW | S )zEReturn a set containing all existing file system items from sys.path.)r r r r �existsr r r )�d�item�_�itemcaser r r �_init_pathinfo� s r' c C sp |dkrt � }d}nd}tjj| |�}yt|d�}W n tk rH dS X |�� �xt|�D ]�\}}|jd�rrq^yX|jd�r�t|� w^|j � }t | |�\}} | |kr�tjj |�r�t jj |� |j| � W q^ tk �rR tdj|d |�t jd � d dl} x>| jt j� � D ],} x$| j� D ]}td | t jd � �q W �qW td t jd � P Y q^X q^W W dQ R X |�rld}|S )z�Process a .pth file within the site-packages directory: For each line in the file, either combine it with sitedir to a path and add that to known_paths, or execute it if it starts with 'import '.

Interface summary: import copy x = copy.copy(y) # make a shallow copy of y x = copy.deepcopy(y) # make a deep copy of y For module specific errors, copy.Error is raised. The difference between shallow and deep copying is only relevant for compound objects (objects that contain other objects, like lists or class instances). - A shallow copy constructs a new compound object and then (to the extent possible) inserts *the same objects* into it that the original contains. - A deep copy constructs a new compound object and then, recursively, inserts *copies* into it of the objects found in the original. Two problems often exist with deep copy operations that don't exist with shallow copy operations: a) recursive objects (compound objects that, directly or indirectly, contain a reference to themselves) may cause a recursive loop b) because deep copy copies *everything* it may copy too much, e.g. administrative data structures that should be shared even between copies Python's deep copy operation avoids these problems by: a) keeping a table of objects already copied during the current copying pass b) letting user-defined classes override the copying operation or the set of components copied This version does not copy types like module, class, function, method, nor stack trace, stack frame, nor file, socket, window, nor array, nor any similar types. Classes can use the same interfaces to control copying that they use to control pickling: they can define methods called __getinitargs__(), __getstate__() and __setstate__(). See the documentation for module "pickle" for information on these methods. � N)�dispatch_tablec @ s e Zd ZdS )�ErrorN)�__name__� __module__� __qualname__� r r � /usr/lib64/python3.6/copy.pyr 7 s r )� PyStringMap�copy�deepcopyc C s� t | �}tj|�}|r || �S yt|t �}W n tk rD d}Y nX |rRt| �S t|dd�}|rj|| �S tj|�}|r�|| �}n>t| dd�}|r�|d�}n$t| dd�}|r�|� }n td| ��t |t �r�| S t | df|�� S )zlShallow copy operation on arbitrary Python objects.

This module defines two useful functions: guess_type(url, strict=True) -- guess the MIME type and encoding of a URL. guess_extension(type, strict=True) -- guess the extension for a given MIME type. It also contains the following, for tuning the behavior: Data: knownfiles -- list of files to parse inited -- flag set when init() has been called suffix_map -- dictionary mapping suffixes to suffixes encodings_map -- dictionary mapping suffixes to encodings types_map -- dictionary mapping suffixes to types Functions: init([files]) -- parse a list of files, default knownfiles (on Windows, the default values are taken from the registry) read_mime_types(file) -- parse one file, return a dictionary or None � N� knownfiles�inited� MimeTypes� guess_type�guess_all_extensions�guess_extension�add_type�init�read_mime_types� suffix_map� encodings_map� types_map� common_typesz/etc/mime.typesz/etc/httpd/mime.typesz/etc/httpd/conf/mime.typesz/etc/apache/mime.typesz/etc/apache2/mime.typesz$/usr/local/etc/httpd/conf/mime.typesz"/usr/local/lib/netscape/mime.typesz/usr/local/etc/mime.typesFc @ sd e Zd ZdZf dfdd�Zddd�Zddd�Zdd d �Zdd d �Zdd d�Z ddd�Z ddd�Z dS )r z�MIME-types datastore.

Return value is a tuple (type, encoding) where type is None if the type can't be guessed (no or unknown suffix) or a string of the form type/subtype, usable for a MIME Content-type header; and encoding is None for no encoding or the name of the program used to encode (e.g. compress or gzip). The mappings are table driven. Encoding suffixes are case sensitive; type suffixes are first tried case sensitive, then case insensitive. The suffixes .tgz, .taz and .tz (case sensitive!) are all mapped to '.tar.gz'. (This is table-driven too, using the dictionary suffix_map.)

It is a "friend" of that class, and imports data either by direct access to members of Profile class, or by reading in a dictionary that was emitted (via marshal) from the Profile class. The big change from the previous Profiler (in terms of raw functionality) is that an "add()" method has been provided to combine Stats from several distinct profile runs. Both the constructor and the add() method now take arbitrarily many file names as arguments. All the print methods now take an argument that indicates how many lines to print. If the arg is a floating point number between 0 and 1.0, then it is taken as a decimal percentage of the available lines to be printed (e.g., .1 means print 10% of all available lines). If it is an integer, it is taken to mean the number of lines of data that you wish to have printed. The sort_stats() method now processes some additional options (i.e., in addition to the old -1, 0, 1, or 2 that are respectively interpreted as 'stdname', 'calls', 'time', and 'cumulative'). It takes an arbitrary number of quoted strings to select the sort order. For example sort_stats('time', 'name') sorts on the major key of 'internal function time', and on the minor key of 'the name of the function'. Look at the two tables in sort_stats() and get_sort_arg_defs(self) for more examples. All methods return self, so you can string together commands like: Stats('foo', 'goo').strip_dirs().sort_stats('calls'). print_stats(5).print_callers(5) N)�streamc G sF |pt j| _t|�sd }n|d }|dd � }| j|� | j|� d S )Nr � )�sys�stdoutr �len�init�add)�selfr �args�arg� r � /usr/lib64/python3.6/pstats.py�__init__A s zStats.__init__c C s� d | _ g | _d | _d| _d| _d| _d| _t� | _i | _ i | _ | j |� y | j � W n8 t k r� td| jrx| jd nd | jd� � Y nX d S )Nr zInvalid timing data %sr � )�file���)� all_callees�files�fcn_list�total_tt� total_calls� prim_calls� max_name_len�set� top_level�stats� sort_arg_dict� load_stats�get_top_level_stats� Exception�printr )r r r r r r K s" z Stats.initc C s� |d kri | _ d S t|t�rxt|d��}tj|�| _ W d Q R X y"tj|�}tj |j �d | }W n Y nX |g| _ n t |d�r�|j � |j | _ i |_ | j s�td| j|f ��d S )N�rbz � create_statsz.Cannot create or construct a %r object from %r)r � isinstance�str�open�marshal�load�os�stat�timeZctime�st_mtimer �hasattrr$ � TypeError� __class__)r r �fZ file_statsr r r r ^ s( zStats.load_statsc C s� x~| j j� D ]p\}\}}}}}| j|7 _| j|7 _| j|7 _d|kr\| jj|� tt|��| j kr tt|��| _ q W d S )N�jprofiler �profiler)r2 r r3 ) r �itemsr r r r r r �func_std_stringr )r �func�cc�nc�tt�ct�callersr r r r t s zStats.get_top_level_statsc G s� |s| S x�t |�D ]�}t| �t|�kr.t|�}| j|j7 _| j|j7 _| j|j7 _| j|j7 _x|jD ]}| jj|� qvW | j |j k r�|j | _ d | _ xJ|j j � D ]<\}}|| j kr�| j | }nddddi f}t ||�| j |< q�W qW | S )Nr )�reversed�typer r r r r r r r r r r4 �add_func_stats)r �arg_list�itemr6 r+ Z old_func_statr r r r ~ s( z Stats.addc C s( t |d��}tj| j|� W dQ R X dS )z:Write the profile data to a file we know how to load back.�wbN)r' r( �dumpr )r �filenamer1 r r r � dump_stats� s zStats.dump_statsr � call count� �cumulative time� � file name� � line number� � function name�name/file/liner �primitive call count� � standard name� � internal time)�callsZncallsZcumtime� cumulativer rC �line�module�nameZnflZpcalls�stdnamer, Ztottimec C s� | j szi | _ }i }xP| jj� D ]B\}}|}x4|r`|s8P ||krJd||< P |||< |dd� }q.W q W x|D ] }||= qlW | j S )z)Expand all abbreviations that are unique.r Nr r )r �sort_arg_dict_defaultr4 )r �dictZbad_list�word�tupZfragmentr r r �get_sort_arg_defs� s zStats.get_sort_arg_defsc G s" |sd| _ | S t|�dkrFt|d t�rFd dddddddi|d g}| j� }f }d| _d}x:|D ]2}||| d }| j||| d 7 _d }qbW g }xB| jj� D ]4\}\}} } } } |j|| | | f| t |�|f � q�W |j t t |�j �d � g | _ } x |D ]}| j|d � �qW | S ) Nr r rY rT r, rR rU r z, )�keyr r )r r r% �intr^ � sort_typer r4 �appendr5 �sortr � TupleComp�compare)r ZfieldZ sort_arg_defsZ sort_tupleZ connectorr\ Z stats_listr6 r7 r8 r9 r: r; r �tupler r r � sort_stats� s2 zStats.sort_statsc C s | j r| j j� | S )N)r �reverse)r r r r � reverse_order� s zStats.reverse_orderc C s� | j }i | _ }d}x�|j� D ]�\}\}}}}} t|�} tt| ��|krTtt| ��}i } x | j� D ]\} } | | t| �< qbW | |kr�t|| ||||| f�|| < q ||||| f|| < q W | j}t� | _}x|D ]}|jt|�� q�W || _ d | _ d | _ | S )Nr ) r r4 �func_strip_pathr r5 r> r r r r r r )r ZoldstatsZnewstatsr r6 r7 r8 r9 r: r; ZnewfuncZ newcallers�func2�callerZold_topZnew_topr r r � strip_dirs� s. zStats.strip_dirsc C s| | j r d S i | _ }xb| jj� D ]T\}\}}}}}||krBi ||< x0|j� D ]$\}} ||krdi ||< | || |< qLW q W d S )N)r r r4 ) r r r6 r7 r8 r9 r: r; rk rl r r r � calc_callees s zStats.calc_calleesc C s |}t |t�rpytj|�}W n& tjk rB |d| 7 }||fS X g }x�|D ] }|jt|��rN|j|� qNW nzt|�}t |t �r�d| ko�dk n r�t || d �}|d |� }n2t |t �r�d| ko�|k n r�|}|d |� }t|�t|�k�r|dt|�t|�|f 7 }||fS )Nz# <Invalid regular expression %r> g g �?g �?r z6 List reduced from %r to %r due to restriction <%r> ) r% r& �re�compile�error�searchr5 rb r �floatr` )r Zsel�list�msgZnew_listZrexr6 �countr r r �eval_print_amount s, "" zStats.eval_print_amountc C s� | j }| jr*| jd d � }d| j d }nt| jj� �}d}x |D ]}| j|||�\}}qBW t|�}|spd|fS t|| j d� |t| j�k r�d}x(|D ] }tt |��|kr�tt |��}q�W |d |fS )Nz Ordered by: � z!

The property list (.plist) file format is a simple XML pickle supporting basic object types, like dictionaries, lists, numbers and strings. Usually the top level object is a dictionary. To write out a plist file, use the dump(value, file) function. 'value' is the top level object, 'file' is a (writable) file object. To parse a plist from a file, use the load(file) function, with a (readable) file object as the only argument. It returns the top level object (again, usually a dictionary). To work with plist data in bytes objects, you can use loads() and dumps(). Values can be strings, integers, floats, booleans, tuples, lists, dictionaries (but only with string keys), Data, bytes, bytearray, or datetime.datetime objects. Generate Plist example: pl = dict( aString = "Doodah", aList = ["A", "B", 12, 32.1, [1, 2, 3]], aFloat = 0.1, anInt = 728, aDict = dict( anotherString = "<hello & hi there!>", aUnicodeValue = "M\xe4ssig, Ma\xdf", aTrueValue = True, aFalseValue = False, ), someData = b"<binary gunk>", someMoreData = b"<lots of binary gunk>" * 10, aDate = datetime.datetime.fromtimestamp(time.mktime(time.gmtime())), ) with open(fileName, 'wb') as fp: dump(pl, fp) Parse Plist example: with open(fileName, 'rb') as fp: pl = load(fp) print(pl["aKey"]) � readPlist� writePlist�readPlistFromBytes�writePlistToBytes�Plist�Data�Dict�InvalidFileException�FMT_XML� FMT_BINARY�load�dump�loads�dumps� N)�BytesIO)�warn)� ParserCreate� PlistFormatzFMT_XML FMT_BINARY)�modulec @ s( e Zd Zf Zdd� Zdd� Zdd� ZdS )� _InternalDictc C s: y | | }W n t k r( t|��Y nX tdtd� |S )NzLAttribute access from plist dicts is deprecated, use d[key] notation instead� )�KeyError�AttributeErrorr �DeprecationWarning)�self�attr�value� r � /usr/lib64/python3.6/plistlib.py� __getattr__V s z_InternalDict.__getattr__c C s t dtd� || |< d S )NzLAttribute access from plist dicts is deprecated, use d[key] notation insteadr )r r )r r r r r r � __setattr___ s z_InternalDict.__setattr__c C s8 y | |= W n t k r& t|��Y nX tdtd� d S )NzLAttribute access from plist dicts is deprecated, use d[key] notation insteadr )r r r r )r r r r r � __delattr__d s z_InternalDict.__delattr__N)�__name__� __module__� __qualname__� __slots__r r r! r r r r r O s r c s e Zd Z� fdd�Z� ZS )r c s t dtd� t� jf |� d S )Nz?The plistlib.Dict class is deprecated, use builtin dict insteadr )r r �super�__init__)r �kwargs)� __class__r r r' o s z Dict.__init__)r" r# r$ r' � __classcell__r r )r) r r m s c c s2 t | t�r(t| |�� }|V W d Q R X n| V d S )N)� isinstance�str�open)� pathOrFile�mode�fpr r r � _maybe_openu s r1 c s4 e Zd ZdZ� fdd�Zedd� �Zdd� Z� ZS )r zuThis class has been deprecated.

The filename argument can be an actual filename (a str or bytes object), or an existing file object to read from or write to. The mode argument can be "r", "rb", "w", "wb", "x", "xb", "a" or "ab" for binary mode, or "rt", "wt", "xt" or "at" for text mode. The default mode is "rb", and the default compresslevel is 9. For binary mode, this function is equivalent to the GzipFile constructor: GzipFile(filename, mode, compresslevel). In this case, the encoding, errors and newline arguments must not be provided. For text mode, a GzipFile object is created, and wrapped in an io.TextIOWrapper instance with the specified encoding, error handling behavior, and line ending(s). �t�bzInvalid mode: %rNz0Argument 'encoding' not supported in binary modez.Argument 'errors' not supported in binary modez/Argument 'newline' not supported in binary mode� �read�writez1filename must be a str or bytes object, or a file) � ValueError�replace� isinstance�str�bytes�os�PathLiker �hasattr� TypeError�io� TextIOWrapper)�filename�mode� compresslevel�encoding�errors�newlineZgz_modeZ binary_file� r# � /usr/lib64/python3.6/gzip.pyr s$ c C s | j tjd|�� d S )Nz<L)r �structZpack)�output�valuer# r# r$ �write32u@ s r( c @ s< e Zd ZdZddd�Zdd� Zddd�Zd d � Zd d � Zd S )� _PaddedFilez�Minimal read-only file object that prepends a string to the contents of an actual file.

At least one of fileobj and filename must be given a non-trivial value. The new class instance is based on fileobj, which can be a regular file, an io.BytesIO object, or any other object which simulates a file. It defaults to None, in which case filename is opened to provide a file object. When fileobj is not None, the filename argument is only used to be included in the gzip file header, which may include the original filename of the uncompressed file. It defaults to the filename of fileobj, if discernible; otherwise, it defaults to the empty string, and in this case the original filename is not included in the header. The mode argument can be any of 'r', 'rb', 'a', 'ab', 'w', 'wb', 'x', or 'xb' depending on whether the file will be read or written. The default is the mode of fileobj if discernible; otherwise, the default is 'rb'. A mode of 'r' is equivalent to one of 'rb', and similarly for 'w' and 'wb', 'a' and 'ab', and 'x' and 'xb'. The compresslevel argument is an integer from 0 to 9 controlling the level of compression; 1 is fastest and produces the least compression, and 9 is slowest and produces the most compression. 0 is no compression at all. The default is 9. The mtime argument is an optional numeric timestamp to be written to the last modification time field in the stream when compressing. If omitted or None, the current time is used. r �UzInvalid mode: {!r}r Nr �namer r �r�w�a�xr )r> r? r@ ) r �format�builtinsr � myfileobj�getattrr r r r �fspath� startswith�READr � _GzipReaderr �BufferedReaderr+ r< �WRITE� _init_write�zlibZ compressobjZDEFLATED� MAX_WBITSZ DEF_MEM_LEVELr � _write_mtime�fileobj�_write_gzip_header)r0 r r r rO �mtime�rawr# r# r$ r3 { s> # zGzipFile.__init__c C sB dd l }|jdtd� | jtkr<| jdd � dkr<| jd S | jS )Nr zuse the name attributer � z.gz���)�warnings�warn�DeprecationWarningr rJ r< )r0 rU r# r# r$ r � s zGzipFile.filenamec C s | j jjS )z0Last modification time read from stream, or None)r+ rR � _last_mtime)r0 r# r# r$ rQ � s zGzipFile.mtimec C s. t | j�}d|dd� d tt| �� d S )Nz<gzip r � �>���)�reprrO �hex�id)r0 �sr# r# r$ �__repr__� s zGzipFile.__repr__c C s. || _ tjd�| _d| _g | _d| _d| _d S )Nr* r )r< rL �crc32�crcr4 Zwritebuf�bufsize�offset)r0 r r# r# r$ rK � s zGzipFile._init_writec C s� | j jd� | j jd� y<tjj| j�}t|t�s<|jd�}|j d�rR|d d � }W n t k rl d}Y nX d}|rzt }| j jt |�jd�� | j }|d kr�tj� }t| j t|�� | j jd� | j jd � |r�| j j|d � d S ) Ns �� zlatin-1s .gzrS r* r � � �� rT )rO r r �path�basenamer< r r �encode�endswith�UnicodeEncodeError�FNAME�chrrN �timer( �int)r0 Zfname�flagsrQ r# r# r$ rP � s, zGzipFile._write_gzip_headerc C s� | j � | jtkr&dd l}t|jd��| jd kr8td��t|t �rLt |�}nt |�}|j }|dkr�| jj | jj|�� | j|7 _tj|| j�| _| j|7 _|S )Nr z$write() on read-only GzipFile objectz!write() on closed GzipFile object)�_check_not_closedr rJ �errno�OSError�EBADFrO r r r r, � memoryview�nbytesr r r4 rL ra rb rd )r0 �datart Zlengthr# r# r$ r � s zGzipFile.writer c C s2 | j � | jtkr&dd l}t|jd��| jj|�S )Nr z$read() on write-only GzipFile object)rs r rG rt ru rv r+ r )r0 r4 rt r# r# r$ r s z GzipFile.readc C s@ | j � | jtkr&ddl}t|jd��|dk r4tj}| jj |�S )zdImplements BufferedIOBase.read1() Reads up to a buffer's worth of data is size is negative.r Nz%read1() on write-only GzipFile object) rs r rG rt ru rv r �DEFAULT_BUFFER_SIZEr+ �read1)r0 r4 rt r# r# r$ r{ s zGzipFile.read1c C s2 | j � | jtkr&dd l}t|jd��| jj|�S )Nr z$peek() on write-only GzipFile object)rs r rG rt ru rv r+ �peek)r0 �nrt r# r# r$ r| # s z GzipFile.peekc C s | j d kS )N)rO )r0 r# r# r$ �closed* s zGzipFile.closedc C s� | j }|d krd S d | _ zP| jtkrR|j| jj� � t|| j� t|| jd@ � n| jt krf| j j � W d | j }|r�d | _ |j � X d S )Nl �� ) rO r rJ r r �flushr( rb r4 rG r+ �closerC )r0 rO rC r# r# r$ r� . s zGzipFile.closec C s4 | j � | jtkr0| jj| jj|�� | jj� d S )N)rs r rJ rO r r r )r0 Z zlib_moder# r# r$ r A s zGzipFile.flushc C s | j j� S )z�Invoke the underlying file object's fileno() method.

Heaps are arrays for which a[k] <= a[2*k+1] and a[k] <= a[2*k+2] for all k, counting elements from 0. For the sake of comparison, non-existing elements are considered to be infinite. The interesting property of a heap is that a[0] is always its smallest element. Usage: heap = [] # creates an empty heap heappush(heap, item) # pushes a new item on the heap item = heappop(heap) # pops the smallest item from the heap item = heap[0] # smallest item on the heap without popping it heapify(x) # transforms list into a heap, in-place, in linear time item = heapreplace(heap, item) # pops and returns smallest item, and adds # new item; the heap size is unchanged Our API differs from textbook heap algorithms as follows: - We use 0-based indexing. This makes the relationship between the index for a node and the indexes for its children slightly less obvious, but is more suitable since Python uses 0-based indexing. - Our heappop() method returns the smallest item, not the largest. These two make it possible to view the heap as a regular Python list without surprises: heap[0] is the smallest item, and heap.sort() maintains the heap invariant! uo Heap queues [explanation by François Pinard] Heaps are arrays for which a[k] <= a[2*k+1] and a[k] <= a[2*k+2] for all k, counting elements from 0. For the sake of comparison, non-existing elements are considered to be infinite. The interesting property of a heap is that a[0] is always its smallest element. The strange invariant above is meant to be an efficient memory representation for a tournament. The numbers below are `k', not a[k]: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 In the tree above, each cell `k' is topping `2*k+1' and `2*k+2'. In a usual binary tournament we see in sports, each cell is the winner over the two cells it tops, and we can trace the winner down the tree to see all opponents s/he had. However, in many computer applications of such tournaments, we do not need to trace the history of a winner. To be more memory efficient, when a winner is promoted, we try to replace it by something else at a lower level, and the rule becomes that a cell and the two cells it tops contain three different items, but the top cell "wins" over the two topped cells. If this heap invariant is protected at all time, index 0 is clearly the overall winner. The simplest algorithmic way to remove it and find the "next" winner is to move some loser (let's say cell 30 in the diagram above) into the 0 position, and then percolate this new 0 down the tree, exchanging values, until the invariant is re-established. This is clearly logarithmic on the total number of items in the tree. By iterating over all items, you get an O(n ln n) sort. A nice feature of this sort is that you can efficiently insert new items while the sort is going on, provided that the inserted items are not "better" than the last 0'th element you extracted. This is especially useful in simulation contexts, where the tree holds all incoming events, and the "win" condition means the smallest scheduled time. When an event schedule other events for execution, they are scheduled into the future, so they can easily go into the heap. So, a heap is a good structure for implementing schedulers (this is what I used for my MIDI sequencer :-). Various structures for implementing schedulers have been extensively studied, and heaps are good for this, as they are reasonably speedy, the speed is almost constant, and the worst case is not much different than the average case. However, there are other representations which are more efficient overall, yet the worst cases might be terrible. Heaps are also very useful in big disk sorts. You most probably all know that a big sort implies producing "runs" (which are pre-sorted sequences, which size is usually related to the amount of CPU memory), followed by a merging passes for these runs, which merging is often very cleverly organised[1]. It is very important that the initial sort produces the longest runs possible. Tournaments are a good way to that. If, using all the memory available to hold a tournament, you replace and percolate items that happen to fit the current run, you'll produce runs which are twice the size of the memory for random input, and much better for input fuzzily ordered. Moreover, if you output the 0'th item on disk and get an input which may not fit in the current tournament (because the value "wins" over the last output value), it cannot fit in the heap, so the size of the heap decreases. The freed memory could be cleverly reused immediately for progressively building a second heap, which grows at exactly the same rate the first heap is melting. When the first heap completely vanishes, you switch heaps and start a new run. Clever and quite effective! In a word, heaps are useful memory structures to know. I use them in a few applications, and I think it is good to keep a `heap' module around. :-) -------------------- [1] The disk balancing algorithms which are current, nowadays, are more annoying than clever, and this is a consequence of the seeking capabilities of the disks. On devices which cannot seek, like big tape drives, the story was quite different, and one had to be very clever to ensure (far in advance) that each tape movement will be the most effective possible (that is, will best participate at "progressing" the merge). Some tapes were even able to read backwards, and this was also used to avoid the rewinding time. Believe me, real good tape sorts were quite spectacular to watch! From all times, sorting has always been a Great Art! :-) �heappush�heappop�heapify� heapreplace�merge�nlargest� nsmallest� heappushpopc C s" | j |� t| dt| �d � dS )z4Push item onto heap, maintaining the heap invariant.� � N)�append� _siftdown�len)�heap�item� r � /usr/lib64/python3.6/heapq.pyr � s c C s. | j � }| r*| d }|| d< t| d� |S |S )zCPop the smallest item off the heap, maintaining the heap invariant.r )�pop�_siftup)r �lastelt� returnitemr r r r � s c C s | d }|| d< t | d� |S )a� Pop and return the current smallest value, and add the new item.

Raise OSError upon failure. file is either a text or byte string giving the name (and the path if the file isn't in the current working directory) of the file to be opened or an integer file descriptor of the file to be wrapped. (If a file descriptor is given, it is closed when the returned I/O object is closed, unless closefd is set to False.) mode is an optional string that specifies the mode in which the file is opened. It defaults to 'r' which means open for reading in text mode. Other common values are 'w' for writing (truncating the file if it already exists), 'x' for exclusive creation of a new file, and 'a' for appending (which on some Unix systems, means that all writes append to the end of the file regardless of the current seek position). In text mode, if encoding is not specified the encoding used is platform dependent. (For reading and writing raw bytes use binary mode and leave encoding unspecified.) The available modes are: ========= =============================================================== Character Meaning --------- --------------------------------------------------------------- 'r' open for reading (default) 'w' open for writing, truncating the file first 'x' create a new file and open it for writing 'a' open for writing, appending to the end of the file if it exists 'b' binary mode 't' text mode (default) '+' open a disk file for updating (reading and writing) 'U' universal newline mode (deprecated) ========= =============================================================== The default mode is 'rt' (open for reading text). For binary random access, the mode 'w+b' opens and truncates the file to 0 bytes, while 'r+b' opens the file without truncation. The 'x' mode implies 'w' and raises an `FileExistsError` if the file already exists. Python distinguishes between files opened in binary and text modes, even when the underlying operating system doesn't. Files opened in binary mode (appending 'b' to the mode argument) return contents as bytes objects without any decoding. In text mode (the default, or when 't' is appended to the mode argument), the contents of the file are returned as strings, the bytes having been first decoded using a platform-dependent encoding or using the specified encoding if given. 'U' mode is deprecated and will raise an exception in future versions of Python. It has no effect in Python 3. Use newline to control universal newlines mode. buffering is an optional integer used to set the buffering policy. Pass 0 to switch buffering off (only allowed in binary mode), 1 to select line buffering (only usable in text mode), and an integer > 1 to indicate the size of a fixed-size chunk buffer. When no buffering argument is given, the default buffering policy works as follows: * Binary files are buffered in fixed-size chunks; the size of the buffer is chosen using a heuristic trying to determine the underlying device's "block size" and falling back on `io.DEFAULT_BUFFER_SIZE`. On many systems, the buffer will typically be 4096 or 8192 bytes long. * "Interactive" text files (files for which isatty() returns True) use line buffering. Other text files use the policy described above for binary files. encoding is the str name of the encoding used to decode or encode the file. This should only be used in text mode. The default encoding is platform dependent, but any encoding supported by Python can be passed. See the codecs module for the list of supported encodings. errors is an optional string that specifies how encoding errors are to be handled---this argument should not be used in binary mode. Pass 'strict' to raise a ValueError exception if there is an encoding error (the default of None has the same effect), or pass 'ignore' to ignore errors. (Note that ignoring encoding errors can lead to data loss.) See the documentation for codecs.register for a list of the permitted encoding error strings. newline is a string controlling how universal newlines works (it only applies to text mode). It can be None, '', '\n', '\r', and '\r\n'. It works as follows: * On input, if newline is None, universal newlines mode is enabled. Lines in the input can end in '\n', '\r', or '\r\n', and these are translated into '\n' before being returned to the caller. If it is '', universal newline mode is enabled, but line endings are returned to the caller untranslated. If it has any of the other legal values, input lines are only terminated by the given string, and the line ending is returned to the caller untranslated. * On output, if newline is None, any '\n' characters written are translated to the system default line separator, os.linesep. If newline is '', no translation takes place. If newline is any of the other legal values, any '\n' characters written are translated to the given string. closedfd is a bool. If closefd is False, the underlying file descriptor will be kept open when the file is closed. This does not work when a file name is given and must be True in that case. The newly created file is non-inheritable. A custom opener can be used by passing a callable as *opener*. The underlying file descriptor for the file object is then obtained by calling *opener* with (*file*, *flags*). *opener* must return an open file descriptor (passing os.open as *opener* results in functionality similar to passing None). open() returns a file object whose type depends on the mode, and through which the standard file operations such as reading and writing are performed. When open() is used to open a file in a text mode ('w', 'r', 'wt', 'rt', etc.), it returns a TextIOWrapper. When used to open a file in a binary mode, the returned class varies: in read binary mode, it returns a BufferedReader; in write binary and append binary modes, it returns a BufferedWriter, and in read/write mode, it returns a BufferedRandom. It is also possible to use a string or bytearray as a file for both reading and writing. For strings StringIO can be used like a file opened in a text mode, and for bytes a BytesIO can be used like a file opened in a binary mode. zinvalid file: %rzinvalid mode: %rzinvalid buffering: %rNzinvalid encoding: %rzinvalid errors: %rzaxrwb+tU�xr �w�a�+�t�b�Uz4mode U cannot be combined with 'x', 'w', 'a', or '+'r z'U' mode is deprecatedr Tz'can't have text and binary mode at oncer z)can't have read/write/append mode at oncez/must have exactly one of read/write/append modez-binary mode doesn't take an encoding argumentz+binary mode doesn't take an errors argumentz+binary mode doesn't take a newline argument� )�openerFzinvalid buffering sizez can't have unbuffered text I/Ozunknown mode: %r���)� isinstance�int�os�fspath�str�bytes� TypeError�set�len� ValueError�warnings�warn�DeprecationWarning�FileIO�isatty�DEFAULT_BUFFER_SIZE�fstat�fileno� st_blksize�OSError�AttributeError�BufferedRandom�BufferedWriter�BufferedReader� TextIOWrapper�mode�close)�filer2 � buffering�encoding�errors�newline�closefdr ZmodesZcreatingZreadingZwritingZ appendingZupdating�textZbinaryr# �raw�result�line_bufferingZbs�buffer� r? � /usr/lib64/python3.6/_pyio.py�open( s� { > rA c @ s e Zd ZdZdd� ZdS )� DocDescriptorz%Helper for builtins.open.__doc__ c C s dt j S )Nz\open(file, mode='r', buffering=-1, encoding=None, errors=None, newline=None, closefd=True) )rA �__doc__)�self�obj�typr? r? r@ �__get__� s zDocDescriptor.__get__N)�__name__� __module__� __qualname__rC rG r? r? r? r@ rB � s rB c @ s e Zd ZdZe� Zdd� ZdS )� OpenWrapperz�Wrapper for builtins.open Trick so that open won't become a bound method when stored as a class variable (as dbm.dumb does).

There is no public constructor. This class provides dummy implementations for many methods that derived classes can override selectively; the default implementations represent a file that cannot be read, written or seeked. Even though IOBase does not declare read, readinto, or write because their signatures will vary, implementations and clients should consider those methods part of the interface. Also, implementations may raise UnsupportedOperation when operations they do not support are called. The basic type used for binary data read from or written to a file is bytes. Other bytes-like objects are accepted as method arguments too. In some cases (such as readinto), a writable object is required. Text I/O classes work with str data. Note that calling any method (even inquiries) on a closed stream is undefined. Implementations may raise OSError in this case. IOBase (and its subclasses) support the iterator protocol, meaning that an IOBase object can be iterated over yielding the lines in a stream. IOBase also supports the :keyword:`with` statement. In this example, fp is closed after the suite of the with statement is complete: with open('spam.txt', 'r') as fp: fp.write('Spam and eggs!') c C s t d| jj|f ��dS )z@Internal: raise an OSError exception for unsupported operations.z%s.%s() not supportedN)rP � __class__rH )rD �namer? r? r@ � _unsupported@ s zIOBase._unsupportedr c C s | j d� dS )a$ Change stream position.

The main difference with RawIOBase is that the read() method supports omitting the size argument, and does not have a default implementation that defers to readinto(). In addition, read(), readinto() and write() may raise BlockingIOError if the underlying raw stream is in non-blocking mode and not ready; unlike their raw counterparts, they will never return None. A typical implementation should not inherit from a RawIOBase implementation, but wrap one. Nc C s | j d� dS )a� Read and return up to size bytes, where size is an int. If the argument is omitted, None, or negative, reads and returns all data until EOF. If the argument is positive, and the underlying raw stream is not 'interactive', multiple raw reads may be issued to satisfy the byte count (unless EOF is reached first). But for interactive raw streams (XXX and for pipes?), at most one raw read will be issued, and a short result does not imply that EOF is imminent. Returns an empty bytes array on EOF.

The mode can be 'r' (default), 'w', 'x' or 'a' for reading, writing, exclusive creation or appending. The file will be created if it doesn't exist when opened for writing or appending; it will be truncated when opened for writing. A FileExistsError will be raised if it already exists when opened for creating. Opening a file for creating implies writing so this mode behaves in a similar way to 'w'. Add a '+' to the mode to allow simultaneous reading and writing. A custom opener can be used by passing a callable as *opener*. The underlying file descriptor for the file object is then obtained by calling opener with (*name*, *flags*). *opener* must return an open file descriptor (passing os.open as *opener* results in functionality similar to passing None). r Nr z$integer argument expected, got floatznegative file descriptorzinvalid mode: %szxrwab+c s s | ]}|d kV qdS )ZrwaxNr? )�.0�cr? r? r@ � <genexpr>� s z"FileIO.__init__.<locals>.<genexpr>r zKMust have exactly one of create/read/write/append mode and at most one plusr Tr r r �O_BINARYZ O_NOINHERIT� O_CLOEXECz'Cannot use closefd=False with file namei� z expected integer from openerzNegative file descriptorFr+ r r ),�_fd�_closefdr r3 r �floatr r r" r r �sum�count�_created� _writable�O_EXCL�O_CREAT� _readable�O_TRUNC� _appending�O_APPEND�O_RDWR�O_RDONLY�O_WRONLY�getattrrA r, �set_inheritabler) �stat�S_ISDIR�st_mode�IsADirectoryErrorr� ZEISDIRr� r- �_blksizer( �_setmoder� rS �lseekr ) rD r4 r2 r9 r �fd�flagsZnoinherit_flagZowned_fdZfdfstatr? r? r@ r� w s� $ zFileIO.__init__c C sD | j dkr@| jr@| j r@dd l}|jd| f td| d� | j� d S )Nr zunclosed file %rr )� stacklevel�source)r� r� re r# r$ �ResourceWarningr3 )rD r# r? r? r@ r] � s zFileIO.__del__c C s t d| jj��d S )Nz cannot serialize '%s' object)r rR rH )rD r? r? r@ r� � s zFileIO.__getstate__c C sl d| j j| j jf }| jr"d| S y | j}W n& tk rR d|| j| j| jf S X d||| j| jf S d S )Nz%s.%sz <%s [closed]>z <%s fd=%d mode=%r closefd=%r>z <%s name=%r mode=%r closefd=%r>) rR rI rJ re rS r- r� r2 r� )rD � class_namerS r? r? r@ r� � s zFileIO.__repr__c C s | j std��d S )NzFile not open for reading)r� rP )rD r? r? r@ rb s zFileIO._checkReadablec C s | j std��d S )NzFile not open for writing)r� rP )rD r_ r? r? r@ rd s zFileIO._checkWritablec C sP | j � | j� |dks |dk r(| j� S ytj| j|�S tk rJ dS X dS )z�Read at most size bytes, returned as bytes.

It defaults to locale.getpreferredencoding(False). errors determines the strictness of encoding and decoding (see the codecs.register) and defaults to "strict". newline can be None, '', '\n', '\r', or '\r\n'. It controls the handling of line endings. If it is None, universal newlines is enabled. With this enabled, on input, the lines endings '\n', '\r', or '\r\n' are translated to '\n' before being returned to the caller. Conversely, on output, '\n' is translated to the system default line separator, os.linesep. If newline is any other of its legal values, that newline becomes the newline when the file is read and it is returned untranslated. On output, '\n' is converted to the newline. If line_buffering is True, a call to flush is implied when a call to write contains a newline character. i NFc C s� |d k r&t |t� r&tdt|�f ��|dkr<td|f ��|d kr�ytj|j� �}W n tt fk rn Y nX |d kr�y dd l }W n t k r� d}Y n X |j d �}t |t�s�td | ��t j|�js�d }t|| ��|d kr�d }nt |t��s td | ��|| _|| _|| _|| _| | _|d k| _|| _|dk| _|�pDtj| _d | _d | _ d| _ d| _ d | _ | j j!� | _"| _#t$| j d�| _%d| _&| j"�r�| j'� �r�| j j(� } | dk�r�y| j)� j*d� W n tk �r� Y nX d S )Nzillegal newline type: %rr r� r� � zillegal newline value: %rr �asciiFzinvalid encoding: %rzG%r is not a text encoding; use codecs.open() to handle arbitrary codecsr� zinvalid errors: %rr� g )Nr r� r� r )+r r r �typer" r �device_encodingr* r- rP �locale� ImportError�getpreferredencodingr� �lookup�_is_text_encoding� LookupErrorr� �_line_buffering� _encoding�_errors�_readuniversal�_readtranslate�_readnl�_writetranslate�linesep�_writenl�_encoder�_decoder�_decoded_chars�_decoded_chars_used� _snapshotr> r^ r� �_tellingro � _has_read1� _b2cratiorc rX � _get_encoderr ) rD r> r6 r7 r8 r= � write_throughr r_ �positionr? r? r@ r� w s` zTextIOWrapper.__init__c C s� dj | jj| jj�}y | j}W n tk r2 Y nX |dj |�7 }y | j}W n tk r` Y nX |dj |�7 }|dj | j� S )Nz<{}.{}z name={0!r}z mode={0!r}z encoding={0!r}>)r� rR rI rJ rS r� r2 r6 )rD r< rS r2 r? r? r@ r� � s zTextIOWrapper.__repr__c C s | j S )N)r )rD r? r? r@ r6 � s zTextIOWrapper.encodingc C s | j S )N)r )rD r? r? r@ r7 � s zTextIOWrapper.errorsc C s | j S )N)r )rD r? r? r@ r= � s z TextIOWrapper.line_bufferingc C s | j S )N)r� )rD r? r? r@ r> � s zTextIOWrapper.bufferc C s | j rtd��| jS )Nz I/O operation on closed file.)re r" r� )rD r? r? r@ r^ � s zTextIOWrapper.seekablec C s | j j� S )N)r> ra )rD r? r? r@ ra � s zTextIOWrapper.readablec C s | j j� S )N)r> rc )rD r? r? r@ rc � s zTextIOWrapper.writablec C s | j j� | j| _d S )N)r> r[ r� r% )rD r? r? r@ r[ � s zTextIOWrapper.flushc C s0 | j d k r,| j r,z | j� W d | j j� X d S )N)r> re r[ r3 )rD r? r? r@ r3 � s zTextIOWrapper.closec C s | j jS )N)r> re )rD r? r? r@ re � s zTextIOWrapper.closedc C s | j jS )N)r> rS )rD r? r? r@ rS � s zTextIOWrapper.namec C s | j j� S )N)r> r* )rD r? r? r@ r* � s zTextIOWrapper.filenoc C s | j j� S )N)r> r' )rD r? r? r@ r' � s zTextIOWrapper.isattyc C s� | j rtd��t|t�s(td|jj ��t|�}| js<| j oBd|k}|rf| jrf| j dkrf|j d| j �}| j pr| j � }|j|�}| jj|� | j r�|s�d|kr�| j� | jd� d| _| jr�| jj� |S )z Write data, where s is a strzwrite to closed filez can't write %s to text streamr� r� r N)re r" r r r rR rH r! r r r r� r r( �encoder> r} r[ �_set_decoded_charsr$ r! r )rD r� ZlengthZhaslf�encoderr r? r? r@ r} s& zTextIOWrapper.writec C s t j| j�}|| j�| _| jS )N)r� �getincrementalencoderr r r )rD Z make_encoderr? r? r@ r( s zTextIOWrapper._get_encoderc C s2 t j| j�}|| j�}| jr(t|| j�}|| _|S )N)r� �getincrementaldecoderr r r r� r r! )rD Z make_decoderr� r? r? r@ � _get_decoder s zTextIOWrapper._get_decoderc C s || _ d| _dS )z Set the _decoded_chars buffer.r N)r" r# )rD �charsr? r? r@ r, ) s z TextIOWrapper._set_decoded_charsc C sF | j }|dkr | j|d� }n| j||| � }| j t|�7 _ |S )z'Advance into the _decoded_chars buffer.N)r# r" r! )rD rl �offsetr1 r? r? r@ �_get_decoded_chars. s z TextIOWrapper._get_decoded_charsc C s$ | j |k rtd��| j |8 _ dS )z!Rewind the _decoded_chars buffer.z"rewind decoded_chars out of boundsN)r# �AssertionError)rD rl r? r? r@ �_rewind_decoded_chars8 s z#TextIOWrapper._rewind_decoded_charsc C s� | j dkrtd��| jr&| j j� \}}| jr<| jj| j�}n| jj| j�}| }| j j ||�}| j |� |r�t |�t | j � | _ nd| _ | jr�||| f| _| S )zQ Read and decode the next chunk of data from the BufferedReader.

The abstract syntax itself might change with each Python release; this module helps to find out programmatically what the current grammar looks like and allows modifications of it. An abstract syntax tree can be generated by passing `ast.PyCF_ONLY_AST` as a flag to the `compile()` builtin function or by using the `parse()` function from this module. The result will be a tree of objects whose classes all inherit from `ast.AST`. A modified abstract syntax tree can be compiled into a Python code object using the built-in `compile()` function. Additionally various helper functions are provided that make working with the trees simpler. The main intention of the helper functions and this module in general is to provide an easy to use interface for libraries that work tightly with the python syntax (template engines for example). :copyright: Copyright 2008 by Armin Ronacher. :license: Python License. � )�*� <unknown>�execc C s t | ||t�S )zn Parse the source into an AST node.

This function may return a value which is forwarded by the `visit` method. This class is meant to be subclassed, with the subclass adding visitor methods. Per default the visitor functions for the nodes are ``'visit_'`` + class name of the node. So a `TryFinally` node visit function would be `visit_TryFinally`. This behavior can be changed by overriding the `visit` method. If no visitor function exists for a node (return value `None`) the `generic_visit` visitor is used instead. Don't use the `NodeVisitor` if you want to apply changes to nodes during traversing. For this a special visitor exists (`NodeTransformer`) that allows modifications. c C s" d|j j }t| || j�}||�S )z Visit a node.Zvisit_)r7 r8 r2 � generic_visit)�selfr( �methodZvisitorr r r �visit� s zNodeVisitor.visitc C s\ xVt |�D ]J\}}t|t�r@x6|D ]}t|t�r"| j|� q"W q t|t�r | j|� q W dS )z9Called if no explicit visitor function exists for a node.N)r6 r r r5 r] )r[ r( r0 r rQ r r r rZ � s zNodeVisitor.generic_visitN)r8 � __module__� __qualname__�__doc__r] rZ r r r r rY � s rY c @ s e Zd ZdZdd� ZdS )�NodeTransformera\ A :class:`NodeVisitor` subclass that walks the abstract syntax tree and allows modification of nodes. The `NodeTransformer` will walk the AST and use the return value of the visitor methods to replace or remove the old node. If the return value of the visitor method is ``None``, the node will be removed from its location, otherwise it is replaced with the return value. The return value may be the original node in which case no replacement takes place. Here is an example transformer that rewrites all occurrences of name lookups (``foo``) to ``data['foo']``:: class RewriteName(NodeTransformer): def visit_Name(self, node): return copy_location(Subscript( value=Name(id='data', ctx=Load()), slice=Index(value=Str(s=node.id)), ctx=node.ctx ), node) Keep in mind that if the node you're operating on has child nodes you must either transform the child nodes yourself or call the :meth:`generic_visit` method for the node first. For nodes that were part of a collection of statements (that applies to all statement nodes), the visitor may also return a list of nodes rather than just a single node. Usually you use the transformer like this:: node = YourTransformer().visit(node) c C s� x�t |�D ]�\}}t|t�r|g }xL|D ]D}t|t�r`| j|�}|d krJq&nt|t�s`|j|� q&|j|� q&W ||d d �< q t|t�r | j|�}|d kr�t||� q t|||� q W |S )N) r6 r r r5 r] rX �append�delattrrC )r[ r( r0 Z old_valueZ new_valuesr rD r r r rZ . s& z NodeTransformer.generic_visitN)r8 r^ r_ r` rZ r r r r ra s "ra N)r r )TF)rJ )T)r` Z_astr �int�float�complexr# r+ r? rF rK rM r6 rG rT rL �objectrY ra r r r r �<module> s 0 % os.cpython-36.opt-1.pyc 0000644 00000071676 15246273046 0010604 0 ustar 00 3 \�� � 0 @ s� d Z ddlZddlZddlZddlZejZddddddd d d d d ddddddddgZdd� Z dd� Z dekr�dZ dZ dd l T ydd l mZ ejd � W n ek r� Y nX ddlZydd l mZ W n ek r� Y nX ddl Z eje e �� [ n�d ek�r�d Z d!Z dd lT ydd lmZ ejd � W n ek �r> Y nX ddlZddlZeje e�� [ydd lmZ W n ek �r� Y nX ned"��eejd#< dd$lmZmZmZm Z m Z m Z m Z m Z [e d%��r�e!� Z"d&d'� Z#e$� Z%e#d(d)� e#d*d+� e#d,d-� e#d.d/� e#d0d1� e#d2d3� e#d4d5� e#d6d7� e#d8d9� e#d:d;� e#d<d=� e#d>d?� e#d@dA� e#dBdC� e#dBdD� e#dEd1� e%Z&e$� Z%e#d(d)� e%Z'e$� Z%e#dFdG� e#dHd+� e#dId-� e#dJdK� e#dLdM� e%j(e� e#dNdO� e#dPd1� e#dQd1� e#dRdS� e dT��r$e dU��r$e#dVdT� e%Z)e$� Z%e#d(d)� e#d,d-� e#d.d/� e#dWdX� e#dYd+� e dZ��rte#d[d-� e#d2d3� e#d\d1� e#d]d/� e#d.d/� e#dEd1� e#d^d/� e%Z*[%[["[#dZ+d_Z,d`Z-d�dcdd�Z.dedf� Z/dgdh� Z0ejdddfdhg� d�djdk�Z1ejdk� e2ehe&k�rFe3ehe)k�rFd�dbddm�dndo�Z4dpdq� Z5ejdo� ye6 W n e7k �rh i Z6Y nX drds� Z8dtdu� Z9dvdw� Z:dxdy� Z;dzd{� Z<d|d}� Z=ejdsdudwdyd{d}g� d�d~d�Z>d�d�d�Z?dd�l@mAZA G d�d�� d�eA�ZByeCZDW n e7k �r d�d�� ZDY nX d�ek�r ejd�� yeEZFW n e7k �rB d�d�� ZFY nX d�ek�rXejd�� d�d�� ZGeG� Z6[Gd�d�d��ZHe d kZIejd�� eI�r�d�d�� ZJeBe6jKeJeLeJeLeDeF�ZM[Jd�d�d��ZNejd�� d�d�� ZOeO� \ZPZQ[Oe d���rHe d�� �rHe d���rHdZRd_ ZSZTejd�d�d�g� d�d�� ZUd�d�� ZVd�d�� ZWd�d�� ZXd�d�� ZYejd�d�d�d�g� e d���rpd�d�� ZZd�d�� Z[ejd�d�g� e d���r�d�d�� Z\d�d�� Z]ejd�d�g� d�d�d�Z^G d�d�� d��Z_d�d� Z`d�d�� Zae d���s�eaZbd�eb_cG d�d�� d�ejd�ZedS )�aN OS routines for NT or Posix depending on what system we're on. This exports: - all functions from posix or nt, e.g. unlink, stat, etc. - os.path is either posixpath or ntpath - os.name is either 'posix' or 'nt' - os.curdir is a string representing the current directory (always '.') - os.pardir is a string representing the parent directory (always '..') - os.sep is the (or a most common) pathname separator ('/' or '\\') - os.extsep is the extension separator (always '.') - os.altsep is the alternate pathname separator (None or '/') - os.pathsep is the component separator used in $PATH etc - os.linesep is the line separator in text files ('\r' or '\n' or '\r\n') - os.defpath is the default search path for executables - os.devnull is the file path of the null device ('/dev/null', etc.) Programs that import and use 'os' stand a better chance of being portable between different platforms. Of course, they must then only use functions that are defined by all platforms (e.g., unlink and opendir), and leave all pathname manipulation to os.path (e.g., split and join). � N�altsep�curdir�pardir�sep�pathsep�linesep�defpath�name�path�devnull�SEEK_SET�SEEK_CUR�SEEK_END�fsencode�fsdecode� get_exec_path�fdopen�popen�extsepc C s | t � kS )N)�globals)r � r �/usr/lib64/python3.6/os.py�_exists% s r c C s2 y t | j�S tk r, dd� t| �D �S X d S )Nc S s g | ]}|d dkr|�qS )r �_r )�.0�nr r r � <listcomp>, s z%_get_exports_list.<locals>.<listcomp>)�list�__all__�AttributeError�dir)�moduler r r �_get_exports_list( s r" �posix� )�*)�_exitr& )�_have_functions�ntz zno os specific module foundzos.path)r r r r r r r r r' c C s" |t kr | tkr tjt | � d S )N)�_globalsr' �_set�add)�str�fnr r r �_addd s r. �HAVE_FACCESSAT�access� HAVE_FCHMODAT�chmod� HAVE_FCHOWNAT�chown� HAVE_FSTATAT�stat�HAVE_FUTIMESAT�utime� HAVE_LINKAT�link� HAVE_MKDIRAT�mkdir� HAVE_MKFIFOAT�mkfifo� HAVE_MKNODAT�mknod� HAVE_OPENAT�open�HAVE_READLINKAT�readlink� HAVE_RENAMEAT�rename�HAVE_SYMLINKAT�symlink� HAVE_UNLINKAT�unlink�rmdir�HAVE_UTIMENSAT� HAVE_FCHDIR�chdir� HAVE_FCHMOD� HAVE_FCHOWN�HAVE_FDOPENDIR�listdir� HAVE_FEXECVE�execve�HAVE_FTRUNCATE�truncate� HAVE_FUTIMENS� HAVE_FUTIMES�HAVE_FPATHCONF�pathconf�statvfs�fstatvfs� HAVE_FSTATVFS� HAVE_LCHFLAGSZchflags� HAVE_LCHMOD�lchown� HAVE_LCHOWN� HAVE_LUTIMES� HAVE_LSTATZ MS_WINDOWS� � � Fc C s� t j| �\}}|s t j|�\}}|r~|r~t j|� r~yt|||� W n tk rX Y nX t}t|t�rrttd�}||kr~dS yt| |� W n( t k r� | s�t j | � r�� Y nX dS )a� makedirs(name [, mode=0o777][, exist_ok=False]) Super-mkdir; create a leaf directory and all intermediate ones. Works like mkdir, except that any intermediate path segment (not just the rightmost) will be created if it does not exist. If the target directory already exists, raise an OSError if exist_ok is False. Otherwise no exception is raised.

Works like rmdir except that, if the leaf directory is successfully removed, directories corresponding to rightmost path segments will be pruned away until either the whole path is consumed or an error occurs.

Works like rename, except creation of any intermediate directories needed to make the new pathname good is attempted first. After the rename, directories corresponding to rightmost path segments of the old name will be pruned until either the whole path is consumed or a nonempty directory is found.

For each directory in the directory tree rooted at top (including top itself, but excluding '.' and '..'), yields a 3-tuple dirpath, dirnames, filenames dirpath is a string, the path to the directory. dirnames is a list of the names of the subdirectories in dirpath (excluding '.' and '..'). filenames is a list of the names of the non-directory files in dirpath. Note that the names in the lists are just names, with no path components. To get a full path (which begins with top) to a file or directory in dirpath, do os.path.join(dirpath, name). If optional arg 'topdown' is true or not specified, the triple for a directory is generated before the triples for any of its subdirectories (directories are generated top down). If topdown is false, the triple for a directory is generated after the triples for all of its subdirectories (directories are generated bottom up). When topdown is true, the caller can modify the dirnames list in-place (e.g., via del or slice assignment), and walk will only recurse into the subdirectories whose names remain in dirnames; this can be used to prune the search, or to impose a specific order of visiting. Modifying dirnames when topdown is false is ineffective, since the directories in dirnames have already been generated by the time dirnames itself is generated. No matter the value of topdown, the list of subdirectories is retrieved before the tuples for the directory and its subdirectories are generated. By default errors from the os.scandir() call are ignored. If optional arg 'onerror' is specified, it should be a function; it will be called with one argument, an OSError instance. It can report the error to continue with the walk, or raise the exception to abort the walk. Note that the filename is available as the filename attribute of the exception object. By default, os.walk does not follow symbolic links to subdirectories on systems that support them. In order to get this functionality, set the optional argument 'followlinks' to true. Caution: if you pass a relative pathname for top, don't change the current working directory between resumptions of walk. walk never changes the current directory, and assumes that the client doesn't either. Example: import os from os.path import join, getsize for root, dirs, files in os.walk('python/Lib/email'): print(root, "consumes", end="") print(sum([getsize(join(root, name)) for name in files]), end="") print("bytes in", len(files), "non-directory files") if 'CVS' in dirs: dirs.remove('CVS') # don't visit CVS directories NFT) �fspath�scandirrn �next� StopIteration�is_dir�appendr � is_symlinkr �islink�join�walk)�top�topdown�onerror� followlinks�dirs�nondirs� walk_dirs� scandir_it�error�entryr} � walk_intor r� r� �dirname�new_pathr r r r� s` : r� �.)�follow_symlinks�dir_fdc c s� t | t� st| d� r t| �} t| d|d�}t| t|d�}z:|s^tj|j �rtt j |t|��rtt || |||�E dH W dt |� X dS )a Directory tree generator. This behaves exactly like walk(), except that it yields a 4-tuple dirpath, dirnames, filenames, dirfd `dirpath`, `dirnames` and `filenames` are identical to walk() output, and `dirfd` is a file descriptor referring to the directory `dirpath`. The advantage of fwalk() over walk() is that it's safe against symlink races (when follow_symlinks is False). If dir_fd is not None, it should be a file descriptor open to a directory, and top should be relative; top will then be relative to that directory. (dir_fd is always supported for fwalk.) Caution: Since fwalk() yields file descriptors, those are only valid until the next iteration step, so you should dup() them if you want to keep them for a longer period. Example: import os for root, dirs, files, rootfd in os.fwalk('python/Lib/email'): print(root, "consumes", end="") print(sum([os.stat(name, dir_fd=rootfd).st_size for name in files]), end="") print("bytes in", len(files), "non-directory files") if 'CVS' in dirs: dirs.remove('CVS') # don't visit CVS directories � __index__F)r� r� )r� N)rl �int�hasattrry r6 rB �O_RDONLY�st�S_ISDIR�st_moder �samestat�_fwalk�close)r� r� r� r� r� �orig_st�topfdr r r �fwalk� s !r� c c s| t | �}g g }}x�|D ]�}y.tjt|| d�j�r>|j|� n |j|� W q tk r� y$tjt|| dd�j�r||j|� W n tk r� wY nX Y qX qW |r�|||| fV x�|D ]�}y t|| |d�} t|t | d�} W n8 tk �r } z|d k �r|| � w�W Y d d } ~ X nX z>|�s0t j | t| ���rRt j ||�} t | | |||�E d H W d t| � X q�W |�sx|||| fV d S )N)r� F)r� r� )rR r� r� r6 r� r~ rn �S_ISLNKrB r� r r� r� r� r� ) r� �toppathr� r� r� �namesr� r� r r� �dirfd�err�dirpathr r r r� � s< r� c G s t | |� dS )zpexecl(file, *args) Execute the executable file with argument list args, replacing the current process.

This module provides functions for calculating statistics of data, including averages, variance, and standard deviation. Calculating averages -------------------- ================== ============================================= Function Description ================== ============================================= mean Arithmetic mean (average) of data. harmonic_mean Harmonic mean of data. median Median (middle value) of data. median_low Low median of data. median_high High median of data. median_grouped Median, or 50th percentile, of grouped data. mode Mode (most common value) of data. ================== ============================================= Calculate the arithmetic mean ("the average") of data: >>> mean([-1.0, 2.5, 3.25, 5.75]) 2.625 Calculate the standard median of discrete data: >>> median([2, 3, 4, 5]) 3.5 Calculate the median, or 50th percentile, of data grouped into class intervals centred on the data values provided. E.g. if your data points are rounded to the nearest whole number: >>> median_grouped([2, 2, 3, 3, 3, 4]) #doctest: +ELLIPSIS 2.8333333333... This should be interpreted in this way: you have two data points in the class interval 1.5-2.5, three data points in the class interval 2.5-3.5, and one in the class interval 3.5-4.5. The median of these data points is 2.8333... Calculating variability or spread --------------------------------- ================== ============================================= Function Description ================== ============================================= pvariance Population variance of data. variance Sample variance of data. pstdev Population standard deviation of data. stdev Sample standard deviation of data. ================== ============================================= Calculate the standard deviation of sample data: >>> stdev([2.5, 3.25, 5.5, 11.25, 11.75]) #doctest: +ELLIPSIS 4.38961843444... If you have previously calculated the mean, you can pass it as the optional second argument to the four "spread" functions to avoid recalculating it: >>> data = [1, 2, 2, 4, 4, 4, 5, 6] >>> mu = mean(data) >>> pvariance(data, mu) 2.5 Exceptions ---------- A single exception is defined: StatisticsError is a subclass of ValueError. �StatisticsError�pstdev� pvariance�stdev�variance�median� median_low� median_high�median_grouped�mean�mode� harmonic_mean� N)�Fraction)�Decimal)�groupby�chain)� bisect_left� bisect_rightc @ s e Zd ZdS )r N)�__name__� __module__� __qualname__� r r �"/usr/lib64/python3.6/statistics.pyr c s c C s� d}t |�\}}||i}|j}ttt|��}xRt| t�D ]D\}} t||�}x0tt | �D ]"\}}|d7 }||d�| ||< qVW q8W d|kr�|d } t| � s�t�nt dd� t |j � �D ��} || |fS )aC _sum(data [, start]) -> (type, sum, count) Return a high-precision sum of the given numeric data as a fraction, together with the type to be converted to and the count of items. If optional argument ``start`` is given, it is added to the total. If ``data`` is empty, ``start`` (defaulting to 0) is returned. Examples -------- >>> _sum([3, 2.25, 4.5, -0.5, 1.0], 0.75) (<class 'float'>, Fraction(11, 1), 5) Some sources of round-off error will be avoided: # Built-in sum returns zero. >>> _sum([1e50, 1, -1e50] * 1000) (<class 'float'>, Fraction(1000, 1), 3000) Fractions and Decimals are also supported: >>> from fractions import Fraction as F >>> _sum([F(2, 3), F(7, 5), F(1, 4), F(5, 6)]) (<class 'fractions.Fraction'>, Fraction(63, 20), 4) >>> from decimal import Decimal as D >>> data = [D("0.1375"), D("0.2108"), D("0.3061"), D("0.0419")] >>> _sum(data) (<class 'decimal.Decimal'>, Fraction(6963, 10000), 4) Mixed types are currently treated as an error, except that int is allowed. r � Nc s s | ]\}}t ||�V qd S )N)r )�.0�d�nr r r � <genexpr>� s z_sum.<locals>.<genexpr>) � _exact_ratio�get�_coerce�int�typer �map� _isfinite�AssertionError�sum�sorted�items) �data�start�countr r ZpartialsZ partials_get�T�typ�values�totalr r r �_sumi s $ r0 c C s( y| j � S tk r" tj| �S X d S )N)Z is_finite�AttributeError�mathZisfinite)�xr r r r$ � s r$ c C s� | t k std��| |kr | S |tks,|t kr0| S | tkr<|S t|| �rJ|S t| |�rX| S t| t�rf|S t|t�rt| S t| t�r�t|t�r�|S t| t�r�t|t�r�| S d}t|| j|jf ��dS )z�Coerce types T and S to a common type, or raise TypeError.

The harmonic mean, sometimes called the subcontrary mean, is the reciprocal of the arithmetic mean of the reciprocals of the data, and is often appropriate when averaging quantities which are rates or ratios, for example speeds. Example: Suppose an investor purchases an equal value of shares in each of three companies, with P/E (price/earning) ratios of 2.5, 3 and 10. What is the average P/E ratio for the investor's portfolio? >>> harmonic_mean([2.5, 3, 10]) # For an equal investment portfolio. 3.6 Using the arithmetic mean would give an average of about 5.167, which is too high. If ``data`` is empty, or any element is less than zero, ``harmonic_mean`` will raise ``StatisticsError``. z.harmonic mean does not support negative valuesr z.harmonic_mean requires at least one data pointr zunsupported typec s s | ]}d | V qdS )r Nr )r r3 r r r r d s z harmonic_mean.<locals>.<genexpr>)rD rS rG r � isinstance�numbersZRealr r7 r0 rR �ZeroDivisionErrorr% rA )r) rQ r r3 r, r/ r+ r r r r = s& " c C s\ t | �} t| �}|dkr td��|d dkr8| |d S |d }| |d | | d S dS )aB Return the median (middle value) of numeric data. When the number of data points is odd, return the middle data point.

In the above example, the values 1, 2, 3, etc. actually represent the midpoint of classes 0.5-1.5, 1.5-2.5, 2.5-3.5, etc. The middle value falls somewhere in class 3.5-4.5, and interpolation is used to estimate it. Optional argument ``interval`` represents the class interval, and defaults to 1. Changing the class interval naturally will change the interpolated 50th percentile value: >>> median_grouped([1, 3, 3, 5, 7], interval=1) 3.25 >>> median_grouped([1, 3, 3, 5, 7], interval=2) 3.5 This function does not check whether the data points are at least ``interval`` apart. r zno median for empty datar rW zexpected number but got %r) r' rG r rT �str�bytesr7 r6 rL rO ) r) Zintervalr r3 �obj�L�l1�l2Zcf�fr r r r � s& c C sB t | �}t|�dkr |d d S |r6tdt|� ��ntd��dS )a� Return the most common data point from discrete or nominal data. ``mode`` assumes discrete data, and returns a single value. This is the standard treatment of the mode as commonly taught in schools: >>> mode([1, 1, 2, 3, 3, 3, 3, 4]) 3 This also works with nominal (non-numeric) data: >>> mode(["red", "blue", "blue", "red", "green", "red", "red"]) 'red' If there is not exactly one most common value, ``mode`` will raise StatisticsError. r r z.no unique mode; found %d equally common valueszno mode for empty dataN)rJ rG r )r) rH r r r r � s c s� � dkrt | �� t� fdd�| D ��\}}}t� fdd�| D ��\}}}||krX||ks\t�||d t| � 8 }|dk s�td| ��||fS )a; Return sum of square deviations of sequence data. If ``c`` is None, the mean is calculated in one pass, and the deviations from the mean are calculated in a second pass. Otherwise, deviations are calculated from ``c`` as given.

The optional argument xbar, if given, should be the mean of the data. If it is missing or None, the mean is automatically calculated. Use this function when your data is a sample from a population. To calculate the variance from the entire population, see ``pvariance``. Examples: >>> data = [2.75, 1.75, 1.25, 0.25, 0.5, 1.25, 3.5] >>> variance(data) 1.3720238095238095 If you have already calculated the mean of your data, you can pass it as the optional second argument ``xbar`` to avoid recalculating it: >>> m = mean(data) >>> variance(data, m) 1.3720238095238095 This function does not check that ``xbar`` is actually the mean of ``data``. Giving arbitrary values for ``xbar`` may lead to invalid or impossible results. Decimals and Fractions are supported: >>> from decimal import Decimal as D >>> variance([D("27.5"), D("30.25"), D("30.25"), D("34.5"), D("41.75")]) Decimal('31.01875') >>> from fractions import Fraction as F >>> variance([F(1, 6), F(1, 2), F(5, 3)]) Fraction(67, 108) rW z*variance requires at least two data pointsr )rD rS rG r ra rA )r) �xbarr r, �ssr r r r " s & c C sH t | �| krt| �} t| �}|dk r,td��t| |�\}}t|| |�S )a� Return the population variance of ``data``. data should be an iterable of Real-valued numbers, with at least one value. The optional argument mu, if given, should be the mean of the data. If it is missing or None, the mean is automatically calculated. Use this function to calculate the variance from the entire population. To estimate the variance from a sample, the ``variance`` function is usually a better choice.

The property list (.plist) file format is a simple XML pickle supporting basic object types, like dictionaries, lists, numbers and strings. Usually the top level object is a dictionary. To write out a plist file, use the dump(value, file) function. 'value' is the top level object, 'file' is a (writable) file object. To parse a plist from a file, use the load(file) function, with a (readable) file object as the only argument. It returns the top level object (again, usually a dictionary). To work with plist data in bytes objects, you can use loads() and dumps(). Values can be strings, integers, floats, booleans, tuples, lists, dictionaries (but only with string keys), Data, bytes, bytearray, or datetime.datetime objects. Generate Plist example: pl = dict( aString = "Doodah", aList = ["A", "B", 12, 32.1, [1, 2, 3]], aFloat = 0.1, anInt = 728, aDict = dict( anotherString = "<hello & hi there!>", aUnicodeValue = "M\xe4ssig, Ma\xdf", aTrueValue = True, aFalseValue = False, ), someData = b"<binary gunk>", someMoreData = b"<lots of binary gunk>" * 10, aDate = datetime.datetime.fromtimestamp(time.mktime(time.gmtime())), ) with open(fileName, 'wb') as fp: dump(pl, fp) Parse Plist example: with open(fileName, 'rb') as fp: pl = load(fp) print(pl["aKey"]) � readPlist� writePlist�readPlistFromBytes�writePlistToBytes�Plist�Data�Dict�InvalidFileException�FMT_XML� FMT_BINARY�load�dump�loads�dumps� N)�BytesIO)�warn)� ParserCreate� PlistFormatzFMT_XML FMT_BINARY)�modulec @ s( e Zd Zf Zdd� Zdd� Zdd� ZdS )� _InternalDictc C s: y | | }W n t k r( t|��Y nX tdtd� |S )NzLAttribute access from plist dicts is deprecated, use d[key] notation instead� )�KeyError�AttributeErrorr �DeprecationWarning)�self�attr�value� r � /usr/lib64/python3.6/plistlib.py� __getattr__V s z_InternalDict.__getattr__c C s t dtd� || |< d S )NzLAttribute access from plist dicts is deprecated, use d[key] notation insteadr )r r )r r r r r r � __setattr___ s z_InternalDict.__setattr__c C s8 y | |= W n t k r& t|��Y nX tdtd� d S )NzLAttribute access from plist dicts is deprecated, use d[key] notation insteadr )r r r r )r r r r r � __delattr__d s z_InternalDict.__delattr__N)�__name__� __module__� __qualname__� __slots__r r r! r r r r r O s r c s e Zd Z� fdd�Z� ZS )r c s t dtd� t� jf |� d S )Nz?The plistlib.Dict class is deprecated, use builtin dict insteadr )r r �super�__init__)r �kwargs)� __class__r r r' o s z Dict.__init__)r" r# r$ r' � __classcell__r r )r) r r m s c c s2 t | t�r(t| |�� }|V W d Q R X n| V d S )N)� isinstance�str�open)� pathOrFile�mode�fpr r r � _maybe_openu s r1 c s4 e Zd ZdZ� fdd�Zedd� �Zdd� Z� ZS )r zuThis class has been deprecated.

Returns a tuple (bits, linkage) which contains information about the bit architecture and the linkage format used for the executable. Both values are returned as strings. Values that cannot be determined are returned as given by the parameter presets. If bits is given as '', the sizeof(pointer) (or sizeof(long) on Python version < 1.5.2) is used as indicator for the supported pointer size. The function relies on the system's "file" command to do the actual work. This is available on most if not all Unix platforms. On some non-Unix platforms where the "file" command does not exist and the executable is set to the Python interpreter binary defaults from _default_architecture are used. r N�Prd � �bitr r4 z32-bit�32bitZN32Zn32bitz64-bitr� ZELFZPEr� r� ZCOFFzMS-DOSr� ) �structZcalcsize�errorr� r� r� r4 r� �_default_architecture)r4 �bits�linkager� �sizeZfileoutr rd r r r � architectureB sL r� � uname_resultz-system node release version machine processorc C s� d} t dk rt S d}ytj� \}}}}}W n tk rB d} Y nX | sdttd|||||f�� �r�| r�tj}d}d}t� }d}d}|dkr�t � \}}}} |r�|r�d}|s�dtj kr�tj j dd�}ntj j dd�}|s�tj j d|�}|�r<t |�\}}}|d k�rd }n4|d k�r<|d k�r<d }d |dd � k�r8d}nd}|d k�rf|�s`|dk�r\d}nd}d }n8|dd� dk�r�t � \}} } } d}dj| �}|�s�| }|dk�r | �s�|dk�r�|}d}y ddl} W n tk �r� Y n&X | jdd�\}}|dk�rd}nd}|�std d�}|d k�r(d}|d k�r6d}|d k�rDd}|d k�rRd}|d k�r`d}|d k�rnd}|d k�r�|d k�r�d }d}t||||||�a t S ) an Fairly portable uname interface.

Based on RFC 854: TELNET Protocol Specification, by J. Postel and J. Reynolds Example: >>> from telnetlib import Telnet >>> tn = Telnet('www.python.org', 79) # connect to finger port >>> tn.write(b'guido\r\n') >>> print(tn.read_all()) Login Name TTY Idle When Where guido Guido van Rossum pts/2 <Dec 2 11:10> snag.cnri.reston.. >>> Note that read_all() won't read until eof -- it just reads some data -- but it guarantees to read at least one byte unless EOF is hit. It is possible to pass a Telnet object to a selector in order to wait until more data is available. Note that in this case, read_eager() may return b'' even if there was data on the socket, because the protocol negotiation may have eaten the data. This is why EOFError is needed in some cases to distinguish between "no data" and "connection closed" (since the socket also appears ready for reading when it is closed). To do: - option negotiation - timeout should be intrinsic to the connection object instead of an option on one of the read calls only � N)� monotonic�Telnet� � � � � � �� �� �� �� �� � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � �! �" �# �$ �% �& �' �( �) �* �+ �, �- �. �/ �0 �1 � � � � PollSelectorc @ s e Zd ZdZddejfdd�Zdejfdd�Zdd � Zd d � Z d d � Z dd� Z dd� Z dd� Z dd� Zd<dd�Zdd� Zdd� Zd d � Zd d � Zd d!� Zd"d#� Zd$d%� Zd&d'� Zd(d)� Zd*d+� Zd,d-� Zd.d/� Zd0d1� Z d2d3� Z d4d5� Z d=d6d7�Z d8d9� Z d:d;� Z!dS )>r a� Telnet interface class. An instance of this class represents a connection to a telnet server. The instance is initially not connected; the open() method must be used to establish a connection. Alternatively, the host name and optional port number can be passed to the constructor, too. Don't try to reopen an already connected instance. This class has many read_*() methods. Note that some of them raise EOFError when the end of the connection is read, because they can return an empty string for other reasons. See the individual doc strings. read_until(expected, [timeout]) Read until the expected string has been seen, or a timeout is hit (default is no timeout); may block. read_all() Read all data until EOF; may block. read_some() Read at least one byte or EOF; may block. read_very_eager() Read all data available already queued or on the socket, without blocking. read_eager() Read either data already queued or some data available on the socket, without blocking. read_lazy() Read all data in the raw queue (processing it first), without doing any socket I/O. read_very_lazy() Reads all data in the cooked queue, without doing any socket I/O. read_sb_data() Reads available data between SB ... SE sequence. Don't block. set_option_negotiation_callback(callback) Each time a telnet option is read on the input flow, this callback (if set) is called with the following parameters : callback(telnet socket, command, option) option will be chr(0) when there is no option. No other action is done afterwards by telnetlib. Nr c C sh t | _|| _|| _|| _d| _d| _d| _d| _d| _ d| _ d| _ d| _ d| _ |dk rd| j|||� dS )z�Constructor.

The first argument is a list of regular expressions, either compiled (re.RegexObject instances) or uncompiled (strings). The optional second argument is a timeout, in seconds; default is no timeout. Return a tuple of three items: the index in the list of the first regular expression that matches; the match object returned; and the text read up till and including the match. If EOF is read and no text was read, raise EOFError. Otherwise, when nothing matches, return (-1, None, text) where text is the text received so far (may be the empty string if a timeout happened). If a regular expression ends with a greedy match (e.g. '.*') or if more than one expression can match the same input, the results are undeterministic, and may depend on the I/O timing.

Intended use is to place the following code in a package's __init__.py: from pkgutil import extend_path __path__ = extend_path(__path__, __name__) This will add to the package's __path__ all subdirectories of directories on sys.path named after the package. This is useful if one wants to distribute different parts of a single logical package as multiple directories. It also looks for *.pkg files beginning where * matches the name argument. This feature is similar to *.pth files (see site.py), except that it doesn't special-case lines starting with 'import'. A *.pkg file is trusted at face value: apart from checking for duplicates, all entries found in a *.pkg file are added to the path, regardless of whether they are exist the filesystem. (This is a feature.) If the input path is not a list (as is the case for frozen packages) it is returned unchanged. The input path is not modified; an extended copy is returned. Items are only appended to the copy at the end. It is assumed that sys.path is a sequence. Items of sys.path that are not (unicode or 8-bit) strings referring to existing directories are ignored. Unicode items of sys.path that cause errors when used as filenames may cause this function to raise an exception (in line with os.path.isdir() behavior). z.pkgNr, r r zCan't open %s: %s � �#)r� �listr� r2 r3 r) r� r r4 �strr r= r �submodule_search_locationsr �appendr@ rG �isfilerh rD �stderr�write�rstripr� )r4 r Z sname_pkgZparent_package�_Z final_nameZ search_path�dirr �portionsr} ZportionZpkgfiler| r� �liner r r r � sP ! c C s� t jj| �}|dkrdS |j}|dks2t|d� r6dS tjj| �pLt jj |�}|dksbt|d� rfdS |j d�}|j dt j j|j�� t j j|� }|j|�S )af Get a resource from a package. This is a wrapper round the PEP 302 loader get_data API. The package argument should be the name of a package, in standard module format (foo.bar). The resource argument should be in the form of a relative filename, using '/' as the path separator. The parent directory name '..' is not allowed, and nor is a rooted name (starting with a '/'). The function returns a binary string, which is the contents of the specified resource. For packages located in the filesystem, which have already been imported, this is the rough equivalent of d = os.path.dirname(sys.modules[package].__file__) data = open(os.path.join(d, resource), 'rb').read() If the package cannot be located or loaded, or it uses a PEP 302 loader which does not support get_data(), then None is returned.

In the two-argument form of the constructor, Fraction(8, 6) will produce a rational number equivalent to 4/3. Both arguments must be Rational. The numerator defaults to 0 and the denominator defaults to 1 so that Fraction(3) == 3 and Fraction() == 0. Fractions can also be constructed from: - numeric strings similar to those accepted by the float constructor (for example, '-2.3' or '1e10') - strings of the form '123/456' - float and Decimal instances - other Rational instances (including integers) � _numerator� _denominatorr NT)� _normalizec sR t t| �j| �}|dk�rdt|�tkr6||_d|_|S t|tj �rV|j |_|j |_|S t|t t f�rx|j� \|_|_|S t|t��rZtj|�}|dkr�td| ��t|jd�p�d�}|jd�}|r�t|�}nvd}|jd�}|�rdt|� }|| t|� }||9 }|jd �} | �rBt| �} | d k�r4|d| 9 }n|d| 9 }|jd �d k�rb| }ntd ��nft|�t k�o�t|�kn �r�n@t|tj ��r�t|tj ��r�|j |j |j |j }}ntd��|d k�r�td| ��|�rBt|�t k�ot|�kn �r(tj||�} |d k �r2| } n t||�} || }|| }||_||_|S )a� Constructs a Rational.

Use this like: __op__, __rop__ = _operator_fallbacks(just_rational_op, operator.op) In general, we want to implement the arithmetic operations so that mixed-mode operations either call an implementation whose author knew about the types of both arguments, or convert both to the nearest built in type and do the operation there. In Fraction, that means that we define __add__ and __radd__ as: def __add__(self, other): # Both types have numerators/denominator attributes, # so do the operation directly if isinstance(other, (int, Fraction)): return Fraction(self.numerator * other.denominator + other.numerator * self.denominator, self.denominator * other.denominator) # float and complex don't have those operations, but we # know about those types, so special case them. elif isinstance(other, float): return float(self) + other elif isinstance(other, complex): return complex(self) + other # Let the other type take over. return NotImplemented def __radd__(self, other): # radd handles more types than add because there's # nothing left to fall back to. if isinstance(other, numbers.Rational): return Fraction(self.numerator * other.denominator + other.numerator * self.denominator, self.denominator * other.denominator) elif isinstance(other, Real): return float(other) + float(self) elif isinstance(other, Complex): return complex(other) + complex(self) return NotImplemented There are 5 different cases for a mixed-type addition on Fraction. I'll refer to all of the above code that doesn't refer to Fraction, float, or complex as "boilerplate". 'r' will be an instance of Fraction, which is a subtype of Rational (r : Fraction <: Rational), and b : B <: Complex. The first three involve 'r + b': 1. If B <: Fraction, int, float, or complex, we handle that specially, and all is well. 2. If Fraction falls back to the boilerplate code, and it were to return a value from __add__, we'd miss the possibility that B defines a more intelligent __radd__, so the boilerplate should return NotImplemented from __add__. In particular, we don't handle Rational here, even though we could get an exact answer, in case the other type wants to do something special. 3. If B <: Fraction, Python tries B.__radd__ before Fraction.__add__. This is ok, because it was implemented with knowledge of Fraction, so it can handle those instances before delegating to Real or Complex. The next two situations describe 'b + r'. We assume that b didn't know about Fraction in its implementation, and that it uses similar boilerplate code: 4. If B <: Rational, then __radd_ converts both to the builtin rational type (hey look, that's us) and proceeds. 5. Otherwise, __radd__ tries to find the nearest common base ABC, and fall back to its builtin type. Since this class doesn't subclass a concrete type, there's no implementation to fall back to, so we need to try as hard as possible to return an actual value, or the user will get a TypeError. c sP t |ttf�r�| |�S t |t�r0� t| �|�S t |t�rH� t| �|�S tS d S )N)r r r r" �complex�NotImplemented)r r )�fallback_operator�monomorphic_operatorr r �forwardv s z-Fraction._operator_fallbacks.<locals>.forward�__c sZ t |tj�r�|| �S t |tj�r4� t|�t| ��S t |tj�rR� t|�t| ��S tS d S )N)r r r ZRealr" �Complexr> r? )r r )r@ rA r r �reverse� s z-Fraction._operator_fallbacks.<locals>.reverseZ__r)r2 �__doc__)rA r@ rB rE r )r@ rA r �_operator_fallbacks& s P z Fraction._operator_fallbacksc C s, | j |j }}t| j| |j| || �S )za + b)r! r r )r r �da�dbr r r �_add� s z Fraction._addc C s, | j |j }}t| j| |j| || �S )za - b)r! r r )r r rH rI r r r �_sub� s z Fraction._subc C s t | j|j | j|j �S )za * b)r r r! )r r r r r �_mul� s z Fraction._mulc C s t | j|j | j|j �S )za / b)r r r! )r r r r r �_div� s z Fraction._divc C s t j| | �S )za // b)r �floor)r r r r r � __floordiv__� s zFraction.__floordiv__c C s t j|| �S )za // b)r rN )r r r r r � __rfloordiv__� s zFraction.__rfloordiv__c C s | | }| || S )za % br )r r �divr r r �__mod__� s zFraction.__mod__c C s || }|| | S )za % br )r r rQ r r r �__rmod__� s zFraction.__rmod__c C s� t |tj�r�|jdkr�|j}|dkr>t| j| | j| dd�S | jdkrft| j| | j| dd�S t| j | | j | dd�S q�t| �t|� S n t| �| S dS )z�a ** b If b is not an integer, the result will be a float or complex since roots are generally irrational.

The builtin open function is defined in this module. At the top of the I/O hierarchy is the abstract base class IOBase. It defines the basic interface to a stream. Note, however, that there is no separation between reading and writing to streams; implementations are allowed to raise an OSError if they do not support a given operation. Extending IOBase is RawIOBase which deals simply with the reading and writing of raw bytes to a stream. FileIO subclasses RawIOBase to provide an interface to OS files. BufferedIOBase deals with buffering on a raw byte stream (RawIOBase). Its subclasses, BufferedWriter, BufferedReader, and BufferedRWPair buffer streams that are readable, writable, and both respectively. BufferedRandom provides a buffered interface to random access streams. BytesIO is a simple stream of in-memory bytes. Another IOBase subclass, TextIOBase, deals with the encoding and decoding of streams into text. TextIOWrapper, which extends it, is a buffered text interface to a buffered raw stream (`BufferedIOBase`). Finally, StringIO is an in-memory stream for text. Argument names are not part of the specification, and only the arguments of open() are intended to be used as keyword arguments. data: DEFAULT_BUFFER_SIZE An int containing the default buffer size used by the module's buffered I/O classes. open() uses the file's blksize (as obtained by os.stat) if possible. z�Guido van Rossum <guido@python.org>, Mike Verdone <mike.verdone@gmail.com>, Mark

The problem: ------------ Suppose you have some data that you want to convert to another format, such as from GIF image format to PPM image format. Maybe the conversion involves several steps (e.g. piping it through compress or uuencode). Some of the conversion steps may require that their input is a disk file, others may be able to read standard input; similar for their output. The input to the entire conversion may also be read from a disk file or from an open file, and similar for its output. The module lets you construct a pipeline template by sticking one or more conversion steps together. It will take care of creating and removing temporary files if they are necessary to hold intermediate data. You can then use the template to do conversions from many different sources to many different destinations. The temporary file names used are different each time the template is used. The templates are objects so you can create templates for many different conversion steps and store them in a dictionary, for instance. Directions: ----------- To create a template: t = Template() To add a conversion step to a template: t.append(command, kind) where kind is a string of two characters: the first is '-' if the command reads its standard input or 'f' if it requires a file; the second likewise for the output. The command must be valid /bin/sh syntax. If input or output files are required, they are passed as $IN and $OUT; otherwise, it must be possible to use the command in a pipeline. To add a conversion step at the beginning: t.prepend(command, kind) To convert a file to another file using a template: sts = t.copy(infile, outfile) If infile or outfile are the empty string, standard input is read or standard output is written, respectively. The return value is the exit status of the conversion pipeline. To open a file for reading or writing through a conversion pipeline: fp = t.open(file, mode) where mode is 'r' to read the file, or 'w' to write it -- just like for the built-in function open() or for os.popen(). To create a new template object initialized to a given one: t2 = t.clone() � N)�quote�TemplateZffz-fzf-z--z.-z-.c @ sp e Zd ZdZdd� Zdd� Zdd� Zdd � Zd d � Zd d � Z dd� Z dd� Z dd� Z dd� Z dd� Zdd� ZdS )r z'Class representing a pipeline template.c C s d| _ | j� dS )z-Template() returns a fresh pipeline template.r N)� debugging�reset)�self� r � /usr/lib64/python3.6/pipes.py�__init__U s zTemplate.__init__c C s d| j f S )z t.__repr__() implements repr(t).z <Template instance, steps=%r>)�steps)r r r r �__repr__Z s zTemplate.__repr__c C s g | _ dS )z<t.reset() restores a pipeline template to its initial state.N)r )r r r r r ^ s zTemplate.resetc C s" t � }| jdd� |_| j|_|S )zbt.clone() returns a new pipeline template with identical initial state as the current one.N)r r r )r �tr r r �cloneb s zTemplate.clonec C s || _ dS )z(t.debug(flag) turns debugging on or off.N)r )r �flagr r r �debugj s zTemplate.debugc C s� t |�t d�k rtd��|tkr.td|f ��|tkr>td��| jr^| jd d tkr^td��|d dkr�tjd |� r�td ��|d dkr�tjd |� r�td ��| jj ||f� d S )z/t.append(cmd, kind) adds a new step at the end.� z%Template.append: cmd must be a stringz Template.append: bad kind %rz-Template.append: SOURCE can only be prepended� z'Template.append: already ends with SINKr �fz\$IN\bz#Template.append: missing $IN in cmdz\$OUT\bz$Template.append: missing $OUT in cmdN���) �type� TypeError� stepkinds� ValueError�SOURCEr �SINK�re�search�append)r �cmd�kindr r r r n s zTemplate.appendc C s� t |�t d�k rtd��|tkr.td|f ��|tkr>td��| jr^| jd d tkr^td��|d dkr�tjd |� r�td ��|d dkr�tjd |� r�td ��| jj d||f� d S )z2t.prepend(cmd, kind) adds a new step at the front.r z&Template.prepend: cmd must be a stringz Template.prepend: bad kind %rz+Template.prepend: SINK can only be appendedr r z,Template.prepend: already begins with SOURCEr z\$IN\bz$Template.prepend: missing $IN in cmdz\$OUT\bz%Template.prepend: missing $OUT in cmdN) r r r r r r r r r �insert)r r r r r r �prepend~ s zTemplate.prependc C s6 |dkr| j |�S |dkr$| j|�S td|f ��dS )z~t.open(file, rw) returns a pipe or file object open for reading or writing;

This module helps scripts to parse the command line arguments in sys.argv. It supports the same conventions as the Unix getopt() function (including the special meanings of arguments of the form `-' and `--'). Long options similar to those supported by GNU software may be used as well via an optional third argument. This module provides two functions and an exception: getopt() -- Parse command line options gnu_getopt() -- Like getopt(), but allow option and non-option arguments to be intermixed. GetoptError -- exception (class) raised with 'opt' attribute, which is the option involved with the exception. � GetoptError�error�getopt� gnu_getopt� N)�gettextc C s | S )N� )�sr r � /usr/lib64/python3.6/getopt.py�_) s r c @ s& e Zd ZdZdZddd�Zdd� ZdS )r � c C s || _ || _tj| ||� d S )N)�msg�opt� Exception�__init__)�selfr r r r r r . s zGetoptError.__init__c C s | j S )N)r )r r r r �__str__3 s zGetoptError.__str__N)r )�__name__� __module__� __qualname__r r r r r r r r r + s c C s� g }t |�t d�kr |g}nt|�}x�| r�| d jd�r�| d dkr�| d dkr^| dd� } P | d jd�r�t|| d dd� || dd� �\}} q&t|| d dd� || dd� �\}} q&W || fS )a@ getopt(args, options[, long_options]) -> opts, args Parses command line options and parameter list. args is the argument list to be parsed, without the leading reference to the running program. Typically, this means "sys.argv[1:]". shortopts is the string of option letters that the script wants to recognize, with options that require an argument followed by a colon (i.e., the same format that Unix getopt() uses). If specified, longopts is a list of strings with the names of the long options which should be supported. The leading '--' characters should not be included in the option name. Options which require an argument should be followed by an equal sign ('='). The return value consists of two elements: the first is a list of (option, value) pairs; the second is the list of program arguments left after the option list was stripped (this is a trailing slice of the first argument). Each option-and-value pair returned has the option as its first element, prefixed with a hyphen (e.g., '-x'), and the option argument as its second element, or an empty string if the option has no argument. The options occur in the list in the same order in which they were found, thus allowing multiple occurrences. Long and short options may be mixed. r r �-z--� N� )�type�list� startswith�do_longs� do_shorts)�args� shortopts�longopts�optsr r r r 8 s (*c C s6 g }g }t |t�r|g}nt|�}|jd�r>|dd� }d}ntjjd�rPd}nd}x�| �r,| d dkrz|| dd� 7 }P | d dd � dkr�t|| d d d� || dd� �\}} qV| d dd� d kr�| d d kr�t|| d dd� || dd� �\}} qV|�r|| 7 }P qV|j | d � | dd� } qVW ||fS ) a getopt(args, options[, long_options]) -> opts, args This function works like getopt(), except that GNU style scanning mode is used by default. This means that option and non-option arguments may be intermixed. The getopt() function stops processing options as soon as a non-option argument is encountered. If the first character of the option string is `+', or if the environment variable POSIXLY_CORRECT is set, then option processing stops as soon as a non-option argument is encountered. �+r NTZPOSIXLY_CORRECTFr z--r r ) � isinstance�strr r �os�environ�getr r �append)r r r r Z prog_argsZall_options_firstr r r r c s2 ( (c C s� y|j d�}W n tk r& d }Y n X |d |� ||d d � }}t||�\}}|r�|d kr�|svttd�| |��|d |dd � }}n|d k r�ttd�| |��| jd| |p�df� | |fS )N�=r z option --%s requires argumentr z%option --%s must not have an argumentz--r )�index� ValueError� long_has_argsr r r' )r r r r �i�optarg�has_argr r r r � s r c s� � fdd�|D �}|s(t td�� � ��� |kr8d� fS � d |krLd� fS t|�dkrjt td�� � ��|d }|jd�}|r�|d d � }||fS ) Nc s g | ]}|j � �r|�qS r )r )�.0�o)r r r � <listcomp>� s z!long_has_args.<locals>.<listcomp>zoption --%s not recognizedFr( Tr z option --%s not a unique prefixr ���)r r �len�endswith)r r Z possibilitiesZ unique_matchr. r )r r r+ � s r+ c C s� x�|dkr�|d |dd � }}t ||�rj|dkr^|sHttd�| |��|d |dd � }}|d }}nd}| jd| |f� qW | |fS )Nr r r z option -%s requires argumentr )� short_has_argr r r' )r Z optstringr r r r- r r r r � s r c C sX x@t t|��D ]0}| || ko(dkn r|jd|d �S qW ttd�| | ��d S )N�:r zoption -%s not recognized)�ranger3 r r r )r r r, r r r r5 � s r5 �__main__r za:bzalpha=Zbeta)�__doc__�__all__r$ r r � ImportErrorr r r r r r r+ r r5 r �sys�print�argvr r r r �<module> s" + 2 socket.cpython-36.pyc 0000644 00000052777 15246273046 0010515 0 ustar 00 3 \3k � @ sp d Z ddlZddlT ddlZddlZddlZddlZddlmZmZ y ddl Z W n e k rh dZ Y nX e e dd�Z e e dd�Z e e d d�Zd d d d dgZejeje�� ejd edd� � ejdedd� � ejdedd� � ejdedd� � dZdZdd� ZeZejj� jd��r�i Z de d < d e d < d e d < d!e d"< d#e d$< d%e d&< d'e d(< d)e d*< d+e d,< d-e d.< d/e d0< d1e d2< d3e d4< d5e d6< d7e d8< ej d9� G d:d;� d;e �Z G d<d=� d=ej�ZdMd>d �Z e!ejd?��r�d@dA� Z"ej dA� e!edB��r de#dfdCdB�Z$ne%e#dfdDdB�Z$ej dB� dEe$_ e ehZ&G dFdG� dGej'�Z(dNdId �Z)e*� Z+e+dfdJd �Z,dOdKdL�Z-dS )Pa0 This module provides socket operations and some related functions.

Convenience function. Connect to *address* (a 2-tuple ``(host, port)``) and return the socket object. Passing the optional *timeout* parameter will set the timeout on the socket instance before attempting to connect. If no *timeout* is supplied, the global default timeout setting returned by :func:`getdefaulttimeout` is used. If *source_address* is set it must be a tuple of (host, port) for the socket to bind as a source address before making the connection. A host of '' or port 0 tells the OS to use the default.

Translate the host/port argument into a sequence of 5-tuples that contain all the necessary arguments for creating a socket connected to that service. host is a domain name, a string representation of an IPv4/v6 address or None. port is a string service name such as 'http', a numeric port number or None. By passing None as the value of host and port, you can pass NULL to the underlying C API. The family, type and proto arguments can be optionally specified in order to narrow the list of addresses returned. Passing zero as a value for each of these arguments selects the full range of results. )r" r� �appendr r r ) r� r� r% r& r' �flagsZaddrlistr� r� r� r� r� r r r r� � s r� )r )r- )r r r r ).r� r" r` �sysrN re �enumr r �errno� ImportErrorr/ r r r �__all__�extend�_get_exports_list�_convertr r� r� r r Z _realsocket�platform�lowerr r r� � Exceptionr r rd r� rx r� r� r� r� rM r �objectr� r r� r r r r �<module>/ s� C $ u ' subprocess.cpython-36.opt-2.pyc 0000644 00000060140 15246273046 0012334 0 ustar 00 3 \�� � @ s4 d dl Z e jdkZd dlZd dlZd dlZd dlZd dlZd dlZd dl Z d dlm Z G dd� de �Z G dd� de �ZG dd � d e �Zer�d dlZd dlZd dlZG d d � d �Znhd dlZd dlZd dlZy d dlZW n ek r� d dlZY nX eed d �Zeed��rej Z nej Z ddddddddddddd dgZ e�r�d dlm Z m!Z!m"Z"m#Z#m$Z$m%Z%m&Z&m'Z' e j(dd d d d d d!d"d g � G d#d$� d$e)�Z*g Z+d%d&� Z,d;Z-d<Z.d=Z/d*d+� Z0d,d-� Z1dd.�d/d�Z2d0d� Z3dd.�d1d�Z4G d2d� de5�Z6ddd3d4�d5d�Z7d6d7� Z8d8d� Z9d9d� Z:e5� Z;G d:d� de5�Z<dS )>� NZwin32)� monotonicc @ s e Zd ZdS )�SubprocessErrorN)�__name__� __module__� __qualname__� r r �"/usr/lib64/python3.6/subprocess.pyr 9 s r c @ s8 e Zd Zd dd�Zdd� Zedd� �Zejdd� �ZdS ) �CalledProcessErrorNc C s || _ || _|| _|| _d S )N)� returncode�cmd�output�stderr)�selfr r r r r r r �__init__C s zCalledProcessError.__init__c C sb | j rN| j dk rNyd| jtj| j �f S tk rJ d| j| j f S X nd| j| j f S d S )Nr zCommand '%s' died with %r.z)Command '%s' died with unknown signal %d.z.Command '%s' returned non-zero exit status %d.)r r �signalZSignals� ValueError)r r r r �__str__I s zCalledProcessError.__str__c C s | j S )N)r )r r r r �stdoutU s zCalledProcessError.stdoutc C s || _ d S )N)r )r �valuer r r r Z s )NN)r r r r r �propertyr �setterr r r r r < s r c @ s8 e Zd Zd dd�Zdd� Zedd� �Zejdd� �ZdS ) �TimeoutExpiredNc C s || _ || _|| _|| _d S )N)r �timeoutr r )r r r r r r r r r h s zTimeoutExpired.__init__c C s d| j | jf S )Nz'Command '%s' timed out after %s seconds)r r )r r r r r n s zTimeoutExpired.__str__c C s | j S )N)r )r r r r r r s zTimeoutExpired.stdoutc C s || _ d S )N)r )r r r r r r v s )NN)r r r r r r r r r r r r r a s r c @ s e Zd ZdZdZdZdZdZdS )� STARTUPINFOr N)r r r �dwFlags� hStdInput� hStdOutput� hStdError� wShowWindowr r r r r � s r ZPIPE_BUFi � PollSelector�Popen�PIPE�STDOUT�call� check_call�getstatusoutput� getoutput� check_output�run�DEVNULL�CompletedProcess)�CREATE_NEW_CONSOLE�CREATE_NEW_PROCESS_GROUP�STD_INPUT_HANDLE�STD_OUTPUT_HANDLE�STD_ERROR_HANDLE�SW_HIDE�STARTF_USESTDHANDLES�STARTF_USESHOWWINDOWr+ r, r- r. r/ r0 r1 r2 c @ s6 e Zd ZdZejfdd�Zdd� Zdd� ZeZ eZ dS ) �HandleFc C s | j sd| _ || � d S )NT)�closed)r � CloseHandler r r �Close� s z Handle.Closec C s | j sd| _ t| �S td��d S )NTzalready closed)r4 �intr )r r r r �Detach� s z Handle.Detachc C s d| j jt| �f S )Nz%s(%d))� __class__r r7 )r r r r �__repr__� s zHandle.__repr__N) r r r r4 �_winapir5 r6 r8 r: �__del__r r r r r r3 � s r3 c C sT xNt d d � D ]>} | jtjd�}|d k ryt j| � W q tk rJ Y qX qW d S )N)� _deadstate)�_active�_internal_poll�sys�maxsize�remover )Zinst�resr r r �_cleanup� s rD � � � c C s* g } t jj}|dkr&| jdd| � | S )Nr �-�O)r@ �flags�optimize�append)�argsr r r r �"_optim_args_from_interpreter_flags� s rN c C s ddddddd�} t � }x:| j� D ].\}}ttj|�}|dkr"|jd || � q"W tjjrh|jd � n$tjjrz|jd � tjjr�|jd � x tj D ]}|jd | � q�W ttdi �}xDdD ]<}||kr�|| }|dkr�|}n d||f }|j d|f� q�W |S )N�d�B�S�v�b�q)�debug�dont_write_bytecode�no_site�verbose� bytes_warning�quietr rH z-Iz-Ez-sz-W� _xoptions� faulthandler� tracemalloc�showalloccount� showrefcount�utf8Tz%s=%sz-X)r\ r] r^ r_ r` ) rN �items�getattrr@ rJ rL �isolated�ignore_environment� no_user_site� warnoptions�extend)Z flag_opt_maprM �flag�optrR Zxoptionsr �argr r r � _args_from_interpreter_flags� s: rk )r c O sF t ||��2}y |j| d�S |j� |j� � Y nX W d Q R X d S )N)r )r �wait�kill)r � popenargs�kwargs�pr r r r# s c O s6 t | |�}|r2|jd�}|d kr(| d }t||��dS )NrM r )r# �getr )rn ro �retcoder r r r r$ ( s c O sT d|krt d��d|kr<|d d kr<|jdd�r4dnd|d< t|t| dd �|��jS ) Nr z3stdout argument not allowed, it will be overridden.�input�universal_newlinesF� � T)r r �check)r rq r( r!

The problem: ------------ Suppose you have some data that you want to convert to another format, such as from GIF image format to PPM image format. Maybe the conversion involves several steps (e.g. piping it through compress or uuencode). Some of the conversion steps may require that their input is a disk file, others may be able to read standard input; similar for their output. The input to the entire conversion may also be read from a disk file or from an open file, and similar for its output. The module lets you construct a pipeline template by sticking one or more conversion steps together. It will take care of creating and removing temporary files if they are necessary to hold intermediate data. You can then use the template to do conversions from many different sources to many different destinations. The temporary file names used are different each time the template is used. The templates are objects so you can create templates for many different conversion steps and store them in a dictionary, for instance. Directions: ----------- To create a template: t = Template() To add a conversion step to a template: t.append(command, kind) where kind is a string of two characters: the first is '-' if the command reads its standard input or 'f' if it requires a file; the second likewise for the output. The command must be valid /bin/sh syntax. If input or output files are required, they are passed as $IN and $OUT; otherwise, it must be possible to use the command in a pipeline. To add a conversion step at the beginning: t.prepend(command, kind) To convert a file to another file using a template: sts = t.copy(infile, outfile) If infile or outfile are the empty string, standard input is read or standard output is written, respectively. The return value is the exit status of the conversion pipeline.

When not given, this defaults to the PEP 3147/PEP 488 location. :param dfile: Purported file name, i.e. the file name that shows up in error messages. Defaults to the source file name. :param doraise: Flag indicating whether or not an exception should be raised when a compile error is found. If an exception occurs and this flag is set to False, a string indicating the nature of the exception will be printed, and the function will return to the caller. If an exception occurs and this flag is set to True, a PyCompileError exception will be raised. :param optimize: The optimization level for the compiler. Valid values are -1, 0, 1 and 2. A value of -1 means to use the optimization level of the current interpreter, as given by -O command line options. :return: Path to the resulting byte compiled file. Note that it isn't necessary to byte-compile Python modules for execution efficiency -- Python itself byte-compiles a module when it is loaded, and if it can, writes out the bytecode to the corresponding .pyc file. However, if a Python installation is shared between users, it is a good idea to byte-compile all modules upon installation, since other users may not be able to write in the source directories, and thus they won't be able to write the .pyc file, and then they would be byte-compiling every module each time it is loaded. This can slow down program start-up considerably. See compileall.py for a script/module that uses this module to byte-compile all installed files (or all files in selected directories). Do note that FileExistsError is raised if cfile ends up pointing at a non-regular file or symlink. Because the compilation uses a file renaming, the resulting file would be regular and thus not the same type of file as it was previously. Nr r r )� optimizationzc{} is a symlink and will be changed into a regular file if import writes a byte-compiled file to itzk{} is a non-regular file and will be changed into a regular one if import writes a byte-compiled file to itz <py_compile>)� _optimize� �mtime�size) � importlib�util�cache_from_source�os�path�islink�FileExistsError�format�exists�isfile� machinery�SourceFileLoader�get_data�source_to_coder r � __class__�sys�stderr�writer �dirname�makedirs� path_stats�_bootstrap_external�_code_to_bytecode� _calc_mode� _write_atomic)r �cfile�dfile�doraise�optimizer r �loader� source_bytes�code�err�py_excr4 � source_stats�bytecode�moder r r r A sF ) c C s" | dkrt jdd� } d}| dgkr�x�t jj� }|s6P |jd�}yt|dd� W q& tk r� } z d}t jjd|j � W Y dd}~X q& t k r� } zd}t jjd| � W Y dd}~X q&X q&W nZxX| D ]P}yt|dd� W q� tk �r } z d}t jjd|j � W Y dd}~X q�X q�W |S ) a� Compile several source files.

Parse enough of a Python file to recognize imports and class and method definitions, and to find out the superclasses of a class. The interface consists of a single function: readmodule_ex(module [, path]) where module is the name of a Python module, and path is an optional list of directories where the module is to be searched. If present, path is prepended to the system search path sys.path. The return value is a dictionary. The keys of the dictionary are the names of the classes defined in the module (including classes that are defined via the from XXX import YYY construct). The values are class instances of the class Class defined here. One special key/value pair is present for packages: the key '__path__' has a list as its value which contains the package search path. A class is described by the class Class in this module. Instances of this class have the following instance variables: module -- the module name name -- the name of the class super -- a list of super classes (Class instances) methods -- a dictionary of methods file -- the file in which the class was defined lineno -- the line in the file on which the class statement occurred The dictionary of methods uses the method names as keys and the line numbers on which the method was defined as values. If the name of a super class is not recognized, the corresponding entry in the list of super classes is not a class instance but a string giving the name of the super class. Since import statements are recognized and imported modules are scanned as well, this shouldn't happen often. A function is described by the class Function in this module. Instances of this class have the following instance variables: module -- the module name name -- the name of the class file -- the file in which the class was defined lineno -- the line in the file on which the class statement occurred � N)�NAME�DEDENT�OP� readmodule� readmodule_ex�Class�Functionc s( e Zd ZdZ� fdd�Zdd� Z� ZS )r z"Class to represent a Python class.c s4 || _ || _|d krg }|| _i | _|| _|| _d S )N)�module�name�super�methods�file�lineno)�selfr r r r r )� __class__� � /usr/lib64/python3.6/pyclbr.py�__init__7 s zClass.__init__c C s || j |< d S )N)r )r r r r r r � _addmethodA s zClass._addmethod)�__name__� __module__� __qualname__�__doc__r r � __classcell__r r )r r r 5 s c @ s e Zd ZdZdd� ZdS )r z.Class to represent a top-level Python functionc C s || _ || _|| _|| _d S )N)r r r r )r r r r r r r r r F s zFunction.__init__N)r r r r r r r r r r D s c C s: i }x0t | |pg �j� D ]\}}t|t�r|||< qW |S )z}Backwards compatible interface.

RFC 3986 (STD66): "Uniform Resource Identifiers" by T. Berners-Lee, R. Fielding and L. Masinter, January 2005. RFC 2732 : "Format for Literal IPv6 Addresses in URL's by R.Hinden, B.Carpenter and L.Masinter, December 1999. RFC 2396: "Uniform Resource Identifiers (URI)": Generic Syntax by T. Berners-Lee, R. Fielding, and L. Masinter, August 1998. RFC 2368: "The mailto URL scheme", by P.Hoffman , L Masinter, J. Zawinski, July 1998. RFC 1808: "Relative Uniform Resource Locators", by R. Fielding, UC Irvine, June 1995. RFC 1738: "Uniform Resource Locators (URL)" by T. Berners-Lee, L. Masinter, M. McCahill, December 1994 RFC 3986 is considered the current standard and any future changes to urlparse module should conform with it. The urlparse module is currently not entirely compliant with this RFC due to defacto scenarios for parsing, and for backward compatibility purposes, some parsing quirks from older RFCs are retained. The testcases in test_urlparse.py provides a good indicator of parsing behavior. The WHATWG URL Parser spec should also be considered. We are not compliant with it either due to existing user code API behavior expectations (Hyrum's Law). It serves as a useful guide when making changes. � )� namedtupleN)�urlparse� urlunparse�urljoin� urldefrag�urlsplit� urlunsplit� urlencode�parse_qs� parse_qsl�quote� quote_plus�quote_from_bytes�unquote� unquote_plus�unquote_to_bytes� DefragResult� ParseResult� SplitResult�DefragResultBytes�ParseResultBytes�SplitResultBytes)� �ftp�http�gopher�nntp�imap�wais�file�https�shttp�mms�prospero�rtsp�rtsps�rtspu�sftp�svn�svn+ssh�ws�wss)r r r r r �telnetr r r r# r! r" �snewsr$ r% r& r' �rsyncr) r* r( �nfs�gitzgit+sshr+ r, z itms-services)r r �hdlr$ r r r! r" r% r& r' �sip�sipsr# r( �tel) r r2 �mailto�newsr- r r r. r3 r4 ) r r r r r! r" r# r r% r& r' r3 r4 ) r r r2 r r r7 r r r! r" r. r r$ zAabcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789+-.z! )� � � c �T � t j � t j � y)zDClear internal performance caches.

The quote function offers a cautious (not minimal) way to quote a string for most of these parts. RFC 3986 Uniform Resource Identifier (URI): Generic Syntax lists the following (un)reserved characters. unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~" reserved = gen-delims / sub-delims gen-delims = ":" / "/" / "?" / "#" / "[" / "]" / "@" sub-delims = "!" / "$" / "&" / "'" / "(" / ")" / "*" / "+" / "," / ";" / "=" Each of the reserved characters is reserved in some component of a URL, but not necessarily in all of them. The quote function %-escapes all characters that are neither in the unreserved chars ("always safe") nor the additional chars set via the safe arg. The default for the safe arg is '/'. The character is reserved, but in typical usage the quote function is being called on a path where the existing slash characters are to be preserved. Python 3.7 updates from using RFC 2396 to RFC 3986 to quote URL strings. Now, "~" is included in the set of unreserved characters. string and safe may be either str or bytes objects. encoding and errors must not be specified if string is a bytes object. The optional encoding and errors parameters specify how to deal with non-ASCII characters, as accepted by the str.encode method. By default, encoding='utf-8' (characters are encoded with UTF-8), and errors='strict' (unsupported characters raise a UnicodeEncodeError). r6 rC z,quote() doesn't support 'encoding' for bytesz*quote() doesn't support 'errors' for bytes)r[ r\ rJ r] r )r3 rs rK rL s r@ r r k sm � �N �&�#� ���M� � � �H� �>� �F�� � �x��0�� � �� J�K� K� � �� H�I� I� �F�D� )�)r? c �� � t | t � rd| vst | t � rd| vrt | |||� S t |t � rd}nd}t | ||z ||� } | j dd� S )z�Like quote(), but also replace ' ' with '+', as required for quoting HTML form values.

The components of a query arg may each be either a string or a bytes type.

It opens the URL and returns the results as file-like object; the returned object has some extra methods described below. The OpenerDirector manages a collection of Handler objects that do all the actual work. Each Handler implements a particular protocol or option. The OpenerDirector is a composite object that invokes the Handlers needed to open the requested URL. For example, the HTTPHandler performs HTTP GET and POST requests and deals with non-error returns. The HTTPRedirectHandler automatically deals with HTTP 301, 302, 303, 307, and 308 redirect errors, and the HTTPDigestAuthHandler deals with digest authentication. urlopen(url, data=None) -- Basic usage is the same as original urllib. pass the url and optionally data to post to an HTTP URL, and get a file-like object back. One difference is that you can also pass a Request instance instead of URL. Raises a URLError (subclass of OSError); for HTTP errors, raises an HTTPError, which can also be treated as a valid response. build_opener -- Function that creates a new OpenerDirector instance. Will install the default handlers. Accepts one or more Handlers as arguments, either instances or Handler classes that it will instantiate. If one of the argument is a subclass of the default handler, the argument will be installed instead of the default. install_opener -- Installs a new opener as the default opener. objects of interest: OpenerDirector -- Sets up the User Agent as the Python-urllib client and manages the Handler classes, while dealing with requests and responses. Request -- An object that encapsulates the state of a request. The state can be as simple as the URL. It can also include extra HTTP headers, e.g. a User-Agent. BaseHandler -- internals: BaseHandler and parent _call_chain conventions Example usage: import urllib.request # set up authentication info authinfo = urllib.request.HTTPBasicAuthHandler() authinfo.add_password(realm='PDQ Application', uri='https://mahler:8092/site-updates.py', user='klem', passwd='geheim$parole') proxy_support = urllib.request.ProxyHandler({"http" : "http://ahad-haam:3128"}) # build a new opener that adds authentication and caching FTP handlers opener = urllib.request.build_opener(proxy_support, authinfo, urllib.request.CacheFTPHandler) # install it urllib.request.install_opener(opener) f = urllib.request.urlopen('https://www.python.org/') � N)�URLError� HTTPError�ContentTooShortError)�urlparse�urlsplit�urljoin�unwrap�quote�unquote� _splittype� _splithost� _splitport� _splituser� _splitpasswd� _splitattr� _splitquery� _splitvalue� _splittag� _to_bytes�unquote_to_bytes� urlunparse)� addinfourl� addclosehookTF)!�Request�OpenerDirector� BaseHandler�HTTPDefaultErrorHandler�HTTPRedirectHandler�HTTPCookieProcessor� ProxyHandler�HTTPPasswordMgr� HTTPPasswordMgrWithDefaultRealm� HTTPPasswordMgrWithPriorAuth�AbstractBasicAuthHandler�HTTPBasicAuthHandler�ProxyBasicAuthHandler�AbstractDigestAuthHandler�HTTPDigestAuthHandler�ProxyDigestAuthHandler� HTTPHandler� FileHandler� FTPHandler�CacheFTPHandler� DataHandler�UnknownHandler�HTTPErrorProcessor�urlopen�install_opener� build_opener� pathname2url� url2pathname� getproxies� urlretrieve� urlcleanup� URLopener�FancyURLopenerz%d.%d� )�cafile�capath� cadefault�contextc �� � |s|s|r�ddl } |j dt d� |� t d� �t s t d� �t j t j j ||�� }|j dg� t |� � }t |� } n3|rt |� � }t |� } nt � t � xa } nt } | j | ||� S ) a� Open the URL url, which can be either a string or a Request object. *data* must be an object specifying additional data to be sent to the server, or None if no such data is needed. See Request for details. urllib.request module uses HTTP/1.1 and includes a "Connection:close" header in its HTTP requests. The optional *timeout* parameter specifies a timeout in seconds for blocking operations like the connection attempt (if not specified, the global default timeout setting will be used). This only works for HTTP, HTTPS and FTP connections. If *context* is specified, it must be a ssl.SSLContext instance describing the various SSL options. See HTTPSConnection for more details. The optional *cafile* and *capath* parameters specify a set of trusted CA certificates for HTTPS requests. cafile should point to a single file containing a bundle of CA certificates, whereas capath should point to a directory of hashed certificate files. More information can be found in ssl.SSLContext.load_verify_locations(). The *cadefault* parameter is ignored. This function always returns an object which can work as a context manager and has the properties url, headers, and status. See urllib.response.addinfourl for more detail on these properties. For HTTP and HTTPS URLs, this function returns a http.client.HTTPResponse object slightly modified. In addition to the three new methods above, the msg attribute contains the same information as the reason attribute --- the reason phrase returned by the server --- instead of the response headers as it is specified in the documentation for HTTPResponse. For FTP, file, and data URLs and requests explicitly handled by legacy URLopener and FancyURLopener classes, this function returns a urllib.response.addinfourl object. Note that None may be returned if no handler handles the request (though the default installed global OpenerDirector uses UnknownHandler to ensure this never happens). In addition, if proxy settings are detected (for example, when a *_proxy environment variable like http_proxy is set), ProxyHandler is default installed and makes sure the requests are handled through the proxy. r NzJcafile, capath and cadefault are deprecated, use a custom context instead.r; zDYou can't pass both context and any of cafile, capath, and cadefaultzSSL support not available)r< r= zhttp/1.1�r? )�warnings�warn�DeprecationWarning� ValueError� _have_ssl�ssl�create_default_context�Purpose� SERVER_AUTH�set_alpn_protocols� HTTPSHandlerr3 �_opener�open) �url�data�timeoutr< r= r> r? rB � https_handler�openers �'/usr/lib64/python3.12/urllib/request.pyr1 r1 � s� � �h ��9���� � � 0�1C�Q� H� � � � �� � � � 8�9� 9��,�,�S�[�[�-D�-D�4:�4:�<�� �"�"�J�<�0�$�W�5� � �m�,�� �$�W�5� � �m�,�� � �'�>�)��&��� �;�;�s�D�'� *�*� c � � | a y �N)rM )rS s rT r2 r2 � s � ��GrU c � � t | � \ }}t j t | |� � 5 }|j � }|dk( r,|s*t j j |� |fcddd� S |r t |d� }n7t j d�� }|j }t j |� |5 ||f} d} d} d} d} d |v rt |d � } |r || | | � |j | � x}rD| t! |� z } |j# |� | d z } |r || | | � |j | � x}r�Dddd� ddd� dk\ r | k rt% d | | fz � � S # 1 sw Y �.xY w# 1 sw Y �2xY w) aW Retrieve a URL into a temporary location on disk.
