Out-of-band default plugin commands available for OOB handler.
|
||||
|
||||
This module implements commands as defined by the MSDP standard
|
||||
(http://tintin.sourceforge.net/msdp/), but is independent of the
|
||||
actual transfer protocol (webclient, MSDP, GMCP etc).
|
||||
|
||||
This module is pointed to by settings.OOB_PLUGIN_MODULES. All functions
|
||||
(not classes) defined globally in this module will be made available
|
||||
to the oob mechanism.
|
||||
|
||||
oob functions have the following call signature:
|
||||
function(oobhandler, session, *args, **kwargs)
|
||||
|
||||
where oobhandler is a back-reference to the central OOB_HANDLER
|
||||
instance and session is the active session to get return data.
|
||||
|
||||
The function names are not case-sensitive (this allows for names
|
||||
like "LIST" which would otherwise collide with Python builtins).
|
||||
|
||||
A function named OOB_ERROR will retrieve error strings if it is
|
||||
defined. It will get the error message as its 3rd argument.
|
||||
|
||||
Data is usually returned via
|
||||
session.msg(oob=(cmdname, (args,), {kwargs}))
|
||||
Note that args, kwargs must be iterable/dict, non-iterables will
|
||||
be interpreted as a new command name.
