Module startup

Monkeypatch for the reloader provided by CherryPy.

This reloader is designed to reload a single package. This is more efficient and, more important, compatible with zipped libraries that may not provide access to the individual files.

Register the TurboGears server with the Bonjour framework.

Currently only Unix-like systems are supported where either the 'avahi' daemon (Linux etc.) is available or the 'dns-sd' program (Mac OS X).

Handles TurboGears tasks when the CherryPy server starts.

This performs the following initialization tasks (in given order):

* Turns off CherryPy's logging filter when in development mode
* If logging is not already set up, turns on old-style stdlib logging.
* Adds a static filter for TurboGears's static files (URL '/tg_static').
* Adds a static filter for TurboGears's JavaScript files (URL '/tg_js').
* Loads the template engines and the base templates.
* Adds the CherryPy request filters to the root controller.
* Adds the decoding filter to the root URL ('/') if enabled in the
  configuration.
* Registers the server with the Bonjour framework, if available.
* Calls 'turbogears.database.bind_metadata' when using SQLAlchemy.
* Loads all turbogears.extensions entry points and calls their
  'start_extension' method.
* Calls the callables registered in 'turbogears.call_on_startup'.
* Starts the TurboGears scheduler.

Handles TurboGears tasks when the CherryPy server stops.

Ends all open database transactions, shuts down all extensions, calls user provided shutdown functions and stops the scheduler.
