e510875f64 Fix certificate expiration scheduler 
timedelta.seconds does not store the total seconds of a time span.
Internally, seconds is the next smaller unit to days, hence
timedelta.seconds will never exceed (or reach) the number of seconds
in a day (60*60*24=86400)

f49311ef9e Add better certificate handling. 
Certificate host names are now matched (using DNS, SRV, XMPPAddr, and
Common Name), along with expiration check.

Scheduled event to reset the stream once the server's cert expires.

Handle invalid cert trust chains gracefully now.

e918a86028 Make the error message better regarding hanged threads. 
All event handlers which call disconnect() MUST be registered using
`add_event_handler(..., threaded=True)` in order to prevent temporarily
deadlocking until a timeout occurs.

This is required because disconnect() waits for the main threads to
exit before returning, including the event processing thread. Since
handlers registered without `threaded=True` run in the event processing
thread, the disconnect() call will deadlock.

bf8a9dc20d Add logging note about potential cause of disconnect() deadlock. 2012-04-29 14:48:14 -07:00
Lance Stout
08716c35fd Set a timeout when waiting for threads. 
If calling disconnect() from a non-threaded event handler, deadlock can
happen as disconnect() is waiting for threads to close, but the event
runner is blocked by a handler waiting for disconnect() to return.

It is best to specify threaded=True for event handlers which may call
disconnect().

fbdf2bed49 Add out_sync filter category. 
Added option to XMLStream.send() to skip applying filters.

Filters in the out_sync group are synced with placing stanza content
either on the wire directly or into the send queue. Because of this,
out_sync filters should not block.

Setting self.reconnect_max_attempts to a non-None value will limit

and raising a 'connection_failed' event.
