From e0c32b6d9bc357e79db04ea3126a614e038af928 Mon Sep 17 00:00:00 2001 From: Brian Beggs Date: Wed, 5 May 2010 02:03:38 +0800 Subject: Fixes for disconnection problems detailed in http://github.com/fritzy/SleekXMPP/issues/#issue/20 Fixes to both ClientXMPP & xmlstream. ClientXMPP was not tracking the changes to authenticated and sessionstarted after the client was disconnected. xmlstream had some funkyness with state in the _process method that was cleaned up and hopefully made a little cleaner. Also changed a DNS issue that was occuring that rendered me unable to disconnect. I would recieve the following error upon reconnect. Exception in thread process: Exception in thread process: Traceback (most recent call last): File "/usr/local/lib/python2.6/threading.py", line 532, in __bootstrap_inner self.run() File "/usr/local/lib/python2.6/threading.py", line 484, in run self.__target(*self.__args, **self.__kwargs) File "/home/macdiesel/tmp/workspace/SleekXMPP/sleekxmpp/xmlstream/xmlstream.py", line 202, in _process self.reconnect() File "/home/macdiesel/tmp/workspace/SleekXMPP/sleekxmpp/__init__.py", line 134, in reconnect XMLStream.reconnect(self) File "/home/macdiesel/tmp/workspace/SleekXMPP/sleekxmpp/xmlstream/xmlstream.py", line 289, in reconnect self.connect() File "/home/macdiesel/tmp/workspace/SleekXMPP/sleekxmpp/__init__.py", line 99, in connect answers = dns.resolver.query("_xmpp-client._tcp.%s" % self.server, "SRV") File "/usr/local/lib/python2.6/site-packages/dns/resolver.py", line 732, in query return get_default_resolver().query(qname, rdtype, rdclass, tcp, source) File "/usr/local/lib/python2.6/site-packages/dns/resolver.py", line 617, in query source=source) File "/usr/local/lib/python2.6/site-packages/dns/query.py", line 113, in udp wire = q.to_wire() File "/usr/local/lib/python2.6/site-packages/dns/message.py", line 404, in to_wire r.add_question(rrset.name, rrset.rdtype, rrset.rdclass) File "/usr/local/lib/python2.6/site-packages/dns/renderer.py", line 152, in add_question self.output.write(struct.pack("!HH", rdtype, rdclass)) TypeError: unsupported operand type(s) for &: 'unicode' and 'long' Seems I was getting this error when calling line 99 in ClientXMPP. You can't bit-shift a 1 and a string and this is why this error is coming up. I removed the "SRV" argument and used the default of 1. not sure exactly what this should be so it may need to be fixed back before it's merged back to trunk.
