xep_0030 still referenced event_handlers. Added the method event_handled
which will return the number of registered handlers for an event to
resolve the issue.
It is now possible to ask for "any number of history stanzas" when
joining a muc (with history=None).
Also we use "maxchars" when asking NO history ("0") since it's a MUST in
the XEP.
And you can specify a message when leaving a MUC.
Forms have default type of 'form'
setFields now uses a list of tuples instead of a dictionary because ordering is important.
getFields defaults to returning a list of tuples, but the use_dict parameter can change that
Chat states may be set using:
msg['chat_state'].active()
msg['chat_state'].composing()
msg['chat_state'].gone()
msg['chat_state'].inactive()
msg['chat_state'].paused()
Checking a chat state can be done with either:
msg['chat_state'].getState()
msg['chat_state'].name
When a message with a chat state is receieved, the following events
may occur:
chatstate_active
chatstate_composing
chatstate_gone
chatstate_inactive
chatstate_paused
where the event data is the message stanza. Note that currently these
events are also triggered for messages sent by SleekXMPP, not just those
received.
Four new events have been added:
disco_info - A disco#info result has been received
disco_info_request - A disco#info request has been received
disco_items - A disco#items result has been received
disco_items_request - A disco#items request has been received
For disco_info_request and disco_items_request two default handlers are registered. These handlers will only run if they are the only handler for these two events so that multiple responses are not returned and cause errors.
In your own handlers for these two events, you can call the default handlers to preserve the static node behaviour as so:
self.plugin['xep_0030'].handle_disco_info(iq, True)
The forwarded=True will disable the check for other registered handlers.
Agents can now dynamically respond to disco requests by using these events.
