Switched out sqlite3 libs in favour of SQLAlchemy v0.9, will gradually migrate dialects and scheme to be fully SQLAlchemy compliant for using there ORM with sessions instead of direct. Fixed getEpisode function to stop making unrequired scene number conversions on already converted data thats available now from cache.

"""Profiler tools for CherryPy.

CherryPy users
|
|
==============
|
|
|
|
You can profile any of your pages as follows::
|
|
|
|
from cherrypy.lib import profiler
|
|
|
|
class Root:
|
|
p = profile.Profiler("/path/to/profile/dir")
|
|
|
|
def index(self):
|
|
self.p.run(self._index)
|
|
index.exposed = True
|
|
|
|
def _index(self):
|
|
return "Hello, world!"
|
|
|
|
cherrypy.tree.mount(Root())
|
|
|
|
You can also turn on profiling for all requests
|
|
using the ``make_app`` function as WSGI middleware.
|
|
|
|
CherryPy developers
|
|
===================
|
|
|
|
This module can be used whenever you make changes to CherryPy,
|
|
to get a quick sanity-check on overall CP performance. Use the
|
|
``--profile`` flag when running the test suite. Then, use the ``serve()``
|
|
function to browse the results in a web browser. If you run this
|
|
module from the command line, it will call ``serve()`` for you.
