SleekXMPP/sleekxmpp/plugins/xep_0078.py
Nathan Fritz 05c9ea5c1d * converted sleekxmpp to Python 3.x
* sleekxmpp no longer spawns threads for callback handlers -- there are now two threads: one for handlers and one for reading. callback handlers can get results from the read queue directly with the "wait" handler which is used in .send() for the reply catching argument.
