Summary: HA replicating subscriptions should not auto-delete queues
Key: QPID-4391
URL: https://issues.apache.org/jira/browse/QPID-4391
Project: Qpid
Issue Type: Bug
Reporter: Alan Conway
Description of problem:
When an auto-delete queue is replicated, the replicating subscription attempts
to auto-delete the queue after it has already been auto-deleted by the closing
of the last non-HA consumer. An issue occurs if a new auto-delete queue with
the same name is created shortly after the deletion of the previously queue.
This can occur when a client subscribes to an auto-delete queue and is
temporarily disconnected from the broker. It is possible for the cancelled HA
subscription to remove the newly created queue from the queue registry since
the old and new queues use the same names. The HA replicating subscription
should not execute the auto-delete logic when the subscription is cancelled.
Version-Release number of selected component (if applicable):
Qpid 0.18
How reproducible:
Frequently
Steps to Reproduce:
Race condition between a consumer auto-deleting and recreating a queue of the
same name and the HA replicating subscription auto-deleting the original queue.
If the HA replicating subscription auto-deletes the original queue after the
new queue is created, the new queue is removed from the queue registry.
Actual results:
New queue is removed from the queue registry.
Expected results:
HA subscription does not attempt to auto-delete the queue and therefore the new
queue is not removed from the queue registry.
