Nathan Mittler commented on AMQCPP-46:
--------------------------------------
Albert,
I've made some updates to trunk to do the automatic closing of comsumers and
producers when you close the session. Could you give that a try?
> ActiveMQConnection doesn't propagate exception listener to underlying
> connector
> -------------------------------------------------------------------------------
>
> Key: AMQCPP-46
> URL: https://issues.apache.org/activemq/browse/AMQCPP-46
> Project: ActiveMQ C++ Client
> Issue Type: Bug
> Affects Versions: 1.1
> Reporter: Albert Strasheim
> Assigned To: Nathan Mittler
> Fix For: 2.0
>
> Attachments: amqconn-exlistener.diff, main.cpp
>
>
> My program is doing the following:
> # Create connection using ActiveMQConnectionFactory
> # Set a simple exception listener that sets a boolean flag
> # Block in receive on consumer
> If I then kill the broker, various exceptions happen, but they are never sent
> to the exception listener, because the exception listener in StompConnector
> is null. It seems to me that ActiveMQConnection should set and get its
> exception listener on its underlying connector and probably doesn't have to
> contain a pointer to the listener itself.
> If I change ActiveMQConnection as in the attached patch to also set the
> exception listener on the underlying connector, my exception listener gets
> called when the broker dies.
> Once I detect the failure, I delete the producer, consumer, session and
> connection that failed. Looks like an uncaught exception is getting thrown
> during the destruction of the producer (which is the first thing I delete
> when cleaning up). The problem here is probably that the connection is trying
> to close down a socket that is already broken and something goes awry. I'm
> not quite sure how to fix this problem.
