It is able to read the master.cf file (which is one style) and files in the style of main.cf (which is a different style, that is used in multiple postfix configuration files). The design of this module is such that when files are edited, a minimum of changes are made to them. Each file should look as if it has been edited by hand; order, comments and whitespace are all preserved. � Nz^\sz/etc/postfix/main.cfz/etc/postfix/master.cfc C s t jj�d�r dS dS )z6 Only load the module if Postfix is installed ZpostfixT)Fz;postfix execution module not loaded: postfix not installed.)�salt�utils�path�which� r r �H/opt/saltstack/salt/lib/python3.10/site-packages/salt/modules/postfix.py� __virtual__ s r c C s� t jj�| d��}t jj�|�� �}W d � n1 s w Y g }i }|�� D ]M}|�� r6|�� � d�r<|� |� q)|�� � � }|d |d |d |d |d |d |d d � |d d� �d �}|d � d |d � �}|� |� |||< q)||fS )a Parse the master.cf file. This file is essentially a whitespace-delimited columnar file. The columns are: service, type, private (yes), unpriv (yes), chroot (yes), wakeup (never), maxproc (100), command + args. This function parses out the columns, leaving empty lines and comments intact. Where the value doesn't detract from the default, a dash (-) will be used. Returns a dict of the active config lines, and a list of the entire file, in order. These compliment each other. �rN�#r � � � � � � � � )�service� conn_type�private�unpriv�chroot�wakeup�maxproc�command) r r �files�fopen� stringutils� to_unicode�read� splitlines�strip� startswith�append�split�join) r �fh_� full_conf� conf_list� conf_dict�line�comps� conf_line�dict_keyr r r � _parse_master& s. � � r. c C � t | �\}}|S )a� Return a dict of active config values.

If the value does not already exist, it will be appended to the end. Because of shell parsing issues, '-' cannot be set as a value, as is normal in the master.cf file; either 'y', 'n' or a number should be used when calling this function from the command line. If the value used matches the default, it will internally be converted to a '-'. Calling this function from the Python API is not affected by this limitation The settings and their default values, in order, are: service (required), conn_type (required), private (y), unpriv (y), chroot (y), wakeup (n), maxproc (100), command (required). By default, this function will write out the changes to the master.cf file, and then returns the full contents of the file. By setting the ``write_conf`` option to ``False``, it will skip writing the file.

This is not just a "name = value" file; there are other rules: * Comments start with # * Any whitespace at the beginning of a line denotes that that line is a continuation from the previous line. * The whitespace rule applies to comments. * Keys defined in the file may be referred to as variables further down in the file. r N���r5 r6 r �=r r )r r r r r r r r r! r# �re�match�SWWSr8 r> r% r" r$ )r r& r' r( r* �pairsr+ r r r � _parse_main� s2 � $rF c C r/ )a Return a dict of active config values. This does not include comments, spacing or order. Bear in mind that order is functionally important in the main.cf file, since keys can be referred to as variables. This means that the data returned from this function should not be used for direct modification of the main.cf file; other functions are available for that.
