ExchangeRegistration shoud NOT automatically add durable Exchanges to
messageStore
----------------------------------------------------------------------------------
Key: QPID-2096
URL: https://issues.apache.org/jira/browse/QPID-2096
Project: Qpid
Issue Type: Bug
Affects Versions: M4, 0.5
Reporter: Martin Ritchie
Summary:
DefaultExchangeRegistry.registerExchange() has a side effect of calling
messageStore.createExchange.
This behaviour is unexpected as DefaultQueueRegistry does not do the same for
queues.
The problem that this has is that on MessageStore recovery the recovered
exchanges will be registered. Which after the MessageStore has been recovered
will cause createExchange to be called. The problem here is that the
createExchange interface is not designed to cope with duplicates. Something
that Derby highlights as it throws primary key constraint violation error.
The solution is to decouple register and create as has been done with queues.
This has not previously been seen as a) the Derby test profile is not run as
often and b) the configuration used did not have an additional durable exchange
defined.
