From 3a22d798f89ebd2516c3da5e960b4f11b495a05c Mon Sep 17 00:00:00 2001 From: Lance Stout Date: Fri, 20 Jan 2012 02:01:08 -0800 Subject: Allow attempting multiple SASL mechs during a single stream. Instead of disconnecting when the first chosen mech fails, we will try all of them once. --- sleekxmpp/features/feature_mechanisms/mechanisms.py | 18 ++++++++++++------ 1 file changed, 12 insertions(+), 6 deletions(-) (limited to 'sleekxmpp') diff --git a/sleekxmpp/features/feature_mechanisms/mechanisms.py b/sleekxmpp/features/feature_mechanisms/mechanisms.py index 1148f06a..cdc17fdf 100644 --- a/sleekxmpp/features/feature_mechanisms/mechanisms.py +++ b/sleekxmpp/features/feature_mechanisms/mechanisms.py @@ -61,6 +61,9 @@ class feature_mechanisms(base_plugin): tls_active=tls_active, mech=self.use_mech) + self.mech_list = set() + self.attempted_mechs = set() + register_stanza_plugin(StreamFeatures, stanza.Mechanisms) self.xmpp.register_stanza(stanza.Success) @@ -73,14 +76,12 @@ class feature_mechanisms(base_plugin): Callback('SASL Success', MatchXPath(stanza.Success.tag_name()), self._handle_success, - instream=True, - once=True)) + instream=True)) self.xmpp.register_handler( Callback('SASL Failure', MatchXPath(stanza.Failure.tag_name()), self._handle_fail, - instream=True, - once=True)) + instream=True)) self.xmpp.register_handler( Callback('SASL Challenge', MatchXPath(stanza.Challenge.tag_name()), @@ -103,10 +104,15 @@ class feature_mechanisms(base_plugin): # server has incorrectly offered it again. return False - mech_list = features['mechanisms'] + self.mech_list = set(features['mechanisms']) + return self._send_auth() + + def _send_auth(self): + mech_list = self.mech_list - self.attempted_mechs self.mech = self.sasl.choose_mechanism(mech_list) if self.mech is not None: + self.attempted_mechs.add(self.mech.name) resp = stanza.Auth(self.xmpp) resp['mechanism'] = self.mech.name resp['value'] = self.mech.process() @@ -133,5 +139,5 @@ class feature_mechanisms(base_plugin): """SASL authentication failed.
