From 1a270dc05cc368000f3545975befa0589031b684 Mon Sep 17 00:00:00 2001 From: Lance Stout Date: Fri, 28 Jan 2011 00:49:37 -0500 Subject: First pass at re-worked stream features. 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') --- sleekxmpp/stanza/stream_features.py | 52 +++++++++++++++++++++++++++++++++++++ 1 file changed, 52 insertions(+) create mode 100644 sleekxmpp/stanza/stream_features.py (limited to 'sleekxmpp/stanza/stream_features.py') diff --git a/sleekxmpp/stanza/stream_features.py b/sleekxmpp/stanza/stream_features.py new file mode 100644 index 00000000..5be2e55f --- /dev/null +++ b/sleekxmpp/stanza/stream_features.py @@ -0,0 +1,52 @@ +""" + SleekXMPP: The Sleek XMPP Library + Copyright (C) 2010 Nathanael C.
