Subject Python session object strangeness
Date Tue, 27 Oct 2009 13:17:15 GMT
Hi, all.

I have a TopicSubscriber Python class that I am writing to enable
my process to handle signals, as well as going quiescent when the
QPID broker goes down and resubscribing when it comes back up.
Right now I have this strangeness happening:

Traceback (most recent call last):
   File "QpidTopicSubscriber.py", line 222, in <module>
     main(sys.argv)
   File "QpidTopicSubscriber.py", line 207, in main
     msg = Q.queue.get(timeout=o.heartbeat)
   File "/usr/lib/python2.5/Queue.py", line 174, in get
     self.not_empty.wait(remaining)
   File "/usr/lib/python2.5/threading.py", line 235, in wait
     _sleep(delay)
   File "QpidTopicSubscriber.py", line 203, in <lambda>
     lambda foo,bar :sigint(foo,bar,Q))
   File "QpidTopicSubscriber.py", line 132, in sigint
     c.stop()
   File "QpidTopicSubscriber.py", line 124, in stop
     self.session.close()
   File "/usr/lib/python2.5/site-packages/qpid/session.py", line 110, in 
close
     self.channel.session_detach(self.name)
AttributeError: 'NoneType' object has no attribute 'session_detach'

Note I have a signal handler that takes the signal details, adds in the
actual subscriber and then calls stop() on the Session object. At that
point I get this exception. From the code I see the .channel attribute
is set to None. What should be happening wqith it?
