Sorry if you get this message twice; launchpad sucks.
I have a long-running server processes that listen for new messages from
some changing set of rooms. I want to make sure that when I'm done with a
particular room, all the resources associated with it are eventually freed.
Here's what my Room init code does:
routing_key = 'rooms.' + self.id
queue_name = routing_key + '::' + CYCLONE_ID
consumer_tag = 'room' + self.id
queue = yield AMQP_CONNECTION.queue(consumer_tag)
msg = yield queue.get()
Note that the AMQP connection+channel are global. When the server wants to
forgot about a room, what do I have to do to ensure that all resources will
eventually be garbage collected? Does it suffice to cancel the consumer? Do
I have to close the TimeoutDeferredQueue? Looking at the code in
protocol.py, it looks like there might be no way to make the channel forget
about the queue. Am I reading that correctly? If so, that means I would need
a new channel for each room, right?
