"""Automatically restart the server when a source file is modified.
|
|
|
|
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.

# -----------------

# If a module is run with "python -m", the current directory (i.e. "")

# is automatically prepended to sys.path, but not if it is run as

# "path/to/file.py". The processing for "-m" rewrites the former to
|
|
# the latter, so subsequent executions won't have the same path as the
|
|
# original.
|
|
#
|
|
# Conversely, when run as path/to/file.py, the directory containing
|
|
# file.py gets added to the path, which can cause confusion as imports
|
|
# may become relative in spite of the future import.
|
|
#
|
|
# We address the former problem by setting the $PYTHONPATH environment
|
|
# variable before re-execution so the new process will see the correct
|
|
# path. We attempt to address the latter problem when tornado.autoreload
|
|
# is run as __main__, although we can't fix the general case because
|
|
# we cannot reliably reconstruct the original command line
|
|
# (http://bugs.python.org/issue14208).
