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.

Configuration system for CherryPy.
|
|
|
|
Configuration in CherryPy is implemented via dictionaries. Keys are strings
|
|
which name the mapped value, which may be of any type.
|
|
|
|
|
|
Architecture
|
|
------------
|
|
|
|
CherryPy Requests are part of an Application, which runs in a global context,
|
|
and configuration data may apply to any of those three scopes:
|
|
|
|
Global
|
|
Configuration entries which apply everywhere are stored in
|
|
cherrypy.config.
|
|
|
|
Application
|
|
Entries which apply to each mounted application are stored
|
|
on the Application object itself, as 'app.config'. This is a two-level
|
|
dict where each key is a path, or "relative URL" (for example, "/" or
|
|
"/path/to/my/page"), and each value is a config dict. Usually, this
|
|
data is provided in the call to tree.mount(root(), config=conf),
|
|
although you may also use app.merge(conf).
|
|
|
|
Request
|
|
Each Request object possesses a single 'Request.config' dict.
|
|
Early in the request process, this dict is populated by merging global
|
|
config entries, Application entries (whose path equals or is a parent
|
|
of Request.path_info), and any config acquired while looking up the
|
|
page handler (see next).
|
|
|
|
|
|
Declaration
|
|
-----------
|
|
|
|
Configuration data may be supplied as a Python dictionary, as a filename,
|
|
or as an open file object. When you supply a filename or file, CherryPy
|
|
uses Python's builtin ConfigParser; you declare Application config by
|
|
writing each path as a section header::
|
|
|
|
[/path/to/my/page]
|
|
request.stream = True
|
|
|
|
To declare global configuration entries, place them in a [global] section.
|
|
|
|
You may also declare config entries directly on the classes and methods
|
|
(page handlers) that make up your CherryPy application via the ``_cp_config``
|
|
attribute. For example::
|
|
|
|
class Demo:
|
|
_cp_config = {'tools.gzip.on': True}
|
|
|
|
def index(self):
|
|
return "Hello world"
|
|
index.exposed = True
|
|
index._cp_config = {'request.show_tracebacks': False}
|
|
|
|
.. note::
|
|
|
|
This behavior is only guaranteed for the default dispatcher.
|
|
Other dispatchers may have different restrictions on where
|
|
you can attach _cp_config attributes.
|
|
|
|
|
|
Namespaces
|
|
----------
|
|
|
|
Configuration keys are separated into namespaces by the first "." in the key.
|
|
Current namespaces:
|
|
|
|
engine
|
|
Controls the 'application engine', including autoreload.
|
|
These can only be declared in the global config.
|
|
|
|
tree
|
|
Grafts cherrypy.Application objects onto cherrypy.tree.
|
|
These can only be declared in the global config.
|
|
|
|
hooks
|
|
Declares additional request-processing functions.
|
|
|
|
log
|
|
Configures the logging for each application.
|
|
These can only be declared in the global or / config.
|
|
|
|
request
|
|
Adds attributes to each Request.
|
|
|
|
response
|
|
Adds attributes to each Response.
|
|
|
|
server
|
|
Controls the default HTTP server via cherrypy.server.
|
|
These can only be declared in the global config.
|
|
|
|
tools
|
|
Runs and configures additional request-processing packages.
|
|
|
|
wsgi
|
|
Adds WSGI middleware to an Application's "pipeline".
|
|
These can only be declared in the app's root config ("/").
|
|
|
|
checker
|
|
Controls the 'checker', which looks for common errors in
|
|
app state (including config) when the engine starts.
|
|
Global config only.
|
|
|
|
The only key that does not exist in a namespace is the "environment" entry.
|
|
This special entry 'imports' other config entries from a template stored in
|
|
cherrypy._cpconfig.environments[environment]. It only applies to the global
|
|
config, and only when you use cherrypy.config.update.
|
|
|
|
You can define your own namespaces to be called at the Global, Application,
|
|
or Request level, by adding a named handler to cherrypy.config.namespaces,
|
|
app.namespaces, or app.request_class.namespaces. The name can
|
|
be any string, and the handler must be either a callable or a (Python 2.5
|
|
style) context manager.
