This version of SickBeard uses both TVDB and TVRage to search and gather it's series data from allowing you to now have access to and download shows that you couldn't before because of being locked into only what TheTVDB had to offer. Also this edition is based off the code we used in our XEM editon so it does come with scene numbering support as well as all the other features our XEM edition has to offer. Please before using this with your existing database (sickbeard.db) please make a backup copy of it and delete any other database files such as cache.db and failed.db if present, we HIGHLY recommend starting out with no database files at all to make this a fresh start but the choice is at your own risk! Enjoy!

"""CherryPy tools. A "tool" is any helper, adapted to CP.
|
|
|
|
Tools are usually designed to be used in a variety of ways (although some
|
|
may only offer one if they choose):
|
|
|
|
Library calls:
|
|
All tools are callables that can be used wherever needed.
|
|
The arguments are straightforward and should be detailed within the
|
|
docstring.
|
|
|
|
Function decorators:
|
|
All tools, when called, may be used as decorators which configure
|
|
individual CherryPy page handlers (methods on the CherryPy tree).
|
|
That is, "@tools.anytool()" should "turn on" the tool via the
|
|
decorated function's _cp_config attribute.
|
|
|
|
CherryPy config:
|
|
If a tool exposes a "_setup" callable, it will be called
|
|
once per Request (if the feature is "turned on" via config).
|
|
|
|
Tools may be implemented as any object with a namespace. The builtins
|
|
are generally either modules or instances of the tools.Tool class.

To use it, have your controllers subclass this base class (it will

turn on the tool for you).
|

You can also supply the following optional config entries:
|
|
|
|
tools.xmlrpc.encoding: 'utf-8'
|
|
tools.xmlrpc.allow_none: 0
|
|
|
|
XML-RPC is a rather discontinuous layer over HTTP; dispatching to the
|
|
appropriate handler must first be performed according to the URL, and
|
|
then a second dispatch step must take place according to the RPC method
|
|
specified in the request body. It also allows a superfluous "/RPC2"
|
|
prefix in the URL, supplies its own handler args in the body, and
|
|
requires a 200 OK "Fault" response instead of 404 when the desired
|
|
method is not found.
|
|
|
|
Therefore, XML-RPC cannot be implemented for CherryPy via a Tool alone.
|
|
This Controller acts as the dispatch target for the first half (based
|
|
on the URL); it then reads the RPC method from the request body and
|
|
does its own second dispatch step based on that method. It also reads
|
|
body params, and returns a Fault on error.
|
|
|
|
The XMLRPCDispatcher strips any /RPC2 prefix; if you aren't using /RPC2
|
|
in your URL's, you can safely skip turning on the XMLRPCDispatcher.

Otherwise, you need to use declare it in config:

request.dispatch: cherrypy.dispatch.XMLRPCDispatcher()
