C++ Broker deletes dynamic bridges too aggressively

      C++ Broker

      Description

      If a dynamic bridge's session has been detached while attempting to propagate a binding event, the broker will delete the bridge. Normally, a detached bridge session will be automatically recovered during the maintenance periodic if possible. Needless to say, auto-deleting the bridge upon a session error prevents this normal recovery path from occurring.

      This event can occur in a production system during broker startup/federation and also during source broker recovery since there is a potential race condition between creation of the source exchange and the creation of the dynamic bridge on the destination broker.

      Log Message:
      Sep 30 19:41:40 localhost qpidd[10497]: 2012-09-30 19:41:40 [Broker] error Cannot propagate binding for dynamic bridge as session has been detached, deleting dynamic bridge

      Steps to reproduce:

      1. src broker: localhost:5801
      2. dst broker: localhost:5803
        #
      3. Create exchange in dst broker
        #
        qpid-config -b localhost:5803 add exchange topic fed.topic

      #

      1. create dynamic bridge
        #
        qpid-route dynamic add localhost:5803 localhost:5801 fed.topic

      #

      1. create dst queue as bind target
        #
        qpid-config -b localhost:5803 add queue fed.topic.queue

      #

      1. create binding on dest exchange
        #
        qpid-config -b localhost:5803 bind fed.topic fed.topic.queue
        qpid-config -b localhost:5803 unbind fed.topic fed.topic.queue
      1. The unbind should not delete the bridge.
