Most applications should not access this module directly. Instead, pass the keyword argument ``autoreload=True`` to the `tornado.web.Application` constructor (or ``debug=True``, which enables this setting and several others). This will enable autoreload mode as well as checking for changes to templates and static resources. Note that restarting is a destructive operation and any requests in progress will be aborted when the process restarts. (If you want to disable autoreload while using other debug-mode features, pass both ``debug=True`` and ``autoreload=False``). This module can also be used as a command-line wrapper around scripts such as unit test runners. See the `main` method for details. The command-line wrapper and Application debug modes can be used together. This combination is encouraged as the wrapper catches syntax errors and other import-time failures, while debug mode catches changes once the server has started. This module depends on `.IOLoop`, so it will not work in WSGI applications and Google App Engine. It also will not work correctly when `.HTTPServer`'s multi-process mode is used. Reloading loses any Python interpreter command-line arguments (e.g. ``-u``) because it re-executes Python using ``sys.executable`` and ``sys.argv``. Additionally, modifying these variables will cause reloading to behave incorrectly. � )�absolute_import�division�print_functionN�__main__)�ioloop)�gen_log)�process)�exec_in�win32F�� c C sd | pt j�� } | tv r dS dt| < tt�dkr t�d� i }t�t |�}t j ||| d�}|� � dS )zzBegins watching source files for changes. .. versionchanged:: 4.1 The ``io_loop`` argument is deprecated.

Scripts may be specified by filename or module name:: python -m tornado.autoreload -m tornado.test.runtests python -m tornado.autoreload tornado/test/runtests.py Running a script with this wrapper is similar to calling `tornado.autoreload.wait` at the end of the script, but this wrapper can catch import-time problems like syntax errors that would otherwise prevent the script from reaching its call to `wait`.
