Backward incompatibility alert!
Please see examples/adhoc_provider.py for how to use the new
plugin implementation, or the test examples in the files
tests/test_stream_xep_0050.py and tests/test_stanza_xep_0050.py.
Major changes:
- May now have zero-step commands. Useful if a command is
intended to be a dynamic status report that doesn't
require any user input.
- May use payloads other than data forms, such as a
completely custom stanza type.
- May include multiple payload items, such as multiple
data forms, or a form and a custom stanza type.
- Includes a command user API for calling adhoc commands
on remote agents and managing the workflow.
- Added support for note elements.
Todo:
- Add prev action support.
You may use register_plugin('old_0050') to continue using the
previous XEP-0050 implementation.
ElementBase instances will display the top-most namespace by default.
StanzaBase instances will NOT display the top-most namespace by default.
May pass True or False to __str__ to override.
We need to check if type="get". otherwise we will send our version
when we will receive the version of the remote entity, and thus
going in an infinite loop.
Can now be used as so:
>>> msg['chat_state']
''
>>> msg
<message />
>>> msg['chat_state'] = 'paused'
>>> msg
<message>
<paused xmlns="http://jabber.org/protocol/chatstates" />
</message>
>>> msg['chat_state']
'paused'
>>> del msg['chat_state']
>>> msg
<message />
Now done more responsibly, saving any existing signal handlers
and calling them when an interrupt occurs in addition to the
one Sleek installs.
NOTE: You may need to explicitly use "kill <process id>" in
order to trigger the proper signal handler execution, and
to raise the "killed" event.
Instead of the actual callback object, return just the name of
the callback object created when using iq.send(callback=..).
This will help prevent memory leaks by not keeping an additional
reference to the object, but still allows for the callback to be
canceled by using self.remove_handler("handler_name").
Waiting until the actual run step means that the handler is not
marked for deletion when checked in the __spawn_event() thread,
causing the callback to stay in the handler list.
This allows exceptions to include the original
content of a stanza in the error response by including
the parameter clear=False when raising the exception.
Stream features now use stanza objects!
Features are given a ranking that expresses the dependency
relationships (since only one feature is negotiated at a time, the
dependency graph can be replaced by a line).
>>> xmpp.register_feature('my_feature', _my_handler,
>>> restart=True, # Requires stream restart
>>> order=600) # Ranking (out of ~ 10,000,
>>> # lower #'s executed first)
SASL mechanisms may now be added or disabled as needed. Each mechanism
is given a priority value indicating the order in which the client
wishes for mechanisms to be tried. Higher priority numbers are executed
first.
>>> xmpp.register_sasl_mechanism('SASL-MECH', _mech_handler,
>>> priority=0)
Disabling a SASL mechanism:
>>> xmpp.remove_sasl_mechanism('ANONYMOUS')
Will now always show top-level namespace, unless it is the same
as the stream's default namespace. Also added the XMPP stream
namespace to the namespace map as 'stream'.
