A file monitor and server restarter.
Use this like:
..code-block:: Python
import reloader
reloader.install()
Then make sure your server is installed with a shell script like::
err=3
while test "$err" -eq 3 ; do
python server.py
err="$?"
done
or is run from this .bat file (if you use Windows)::
@echo off
:repeat
python server.py
if %errorlevel% == 3 goto repeat
or run a monitoring process in Python (``paster serve --reload`` does
this).
Use the ``watch_file(filename)`` function to cause a reload/restart for
other other non-Python files (e.g., configuration files). If you have
a dynamic set of files that grows over time you can use something like::
def watch_config_files():
return CONFIG_FILE_CACHE.keys()
paste.reloader.add_file_callback(watch_config_files)
Then every time the reloader polls files it will call
``watch_config_files`` and check all the filenames it returns.

Install the reloading monitor.
On some platforms server threads may not terminate when the main
thread does, causing ports to remain open/locked. The
``raise_keyboard_interrupt`` option creates a unignorable signal
which causes the whole application to shut-down (rudely).

Monitor that utilizes Jython's special
``_systemrestart.SystemRestart`` exception.
When raised from the main thread it causes Jython to reload
the interpreter in the existing Java process (avoiding
startup time).
Note that this functionality of Jython is experimental and
may change in the future.
