Justin Ross updated QPID-4391:
------------------------------
Component/s: C++ Clustering
> 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
> Components: C++ Clustering
> Reporter: Alan Conway
> Fix For: 0.19
>
>
> 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.
