If wait=True, then the disconnect call will block until
the send queue has emptied.
WARNING: Using wait=True when more stanzas are being added to the
queue than can be processed such that the queue is never empty
will cause the disconnect call to block indefinitely without actually
disconnecting.
The error bubbles through the event processing loop, breaking it and
hanging the application.
Instead, there is now a .exception(e) method on XMLStream which may
be overridden or reassigned that will receive all unhandled exceptions
(read: not XMPPError) from event and stream handlers.
If a stanza handler raised an exception, the exception was processed
and replied by the modified stanza, not a stanza with the original
content.
A copy is now made before handler processing, and if an exception occurs
it is the copy that processes the exception using the original content.
For now, session_end is the same as disconnected, but once support is
added later for stream management, the two events will become distinct.
Plugins should add handlers for session_end for cleaning any session
state.
Backoff was only being done for the initial connection attempt
before. Now any reconnection will start with a minimum 1 sec
delay which will approximately double between attempts.
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.
Daemonized threads exit once the main program has quit,
and the only threads left running are all daemon threads.
Should fix hanging clients while not trampling over anyone
else's signal handlers.
Support is only for adding literal XML content
to stanzas. Full support for things like multiple
message bodies with different xml:lang values is
still in the works.
* check_stanza does not require stanza_class parameter. Introspection!
* check_message, check_iq, and check_presence removed -- use check
instead.
* stream_send_stanza, stream_send_message, stream_send_iq, and
stream_send_presence removed -- use send instead.
* Use recv instead of recv_message, recv_presence, etc.
* check_jid instead of check_JID
* stream_start may accept multi=True to return a new SleekTest instance
for testing multiple streams at once.
