--------------------------------
Summary: race between auto-delete and re-declare/consume
Key: QPID-7302
URL: https://issues.apache.org/jira/browse/QPID-7302
Project: Qpid
Issue Type: Bug
Components: C++ Broker, C++ Client
Affects Versions: qpid-cpp-0.34
Reporter: Gordon Sim
Assignee: Gordon Sim
Fix For: qpid-cpp-next
In AMQP 0-10, declare and consume are two distinct operations. When creating a
receiver through qpid::messaging, we first declare then consume from the queue.
For a timed auto-delete queue, the delayed auto-delete can tae place between
the declare and the consume, resulting in a session error. It would be nice to
avoid this. The workaround of course is to set the delay for auto-delete to be
sufficiently large that the client will either have reconnected or is likely
not reconnecting.
However a simple solution would be to reset the timer on the declare, allowing
time for the consume.
This does not prevent the race between a non-timed auto-delete triggered by one
session and declare/consume from a different client connection.
