Kim van der Riet commented on QPID-3304:

Checked in Gordon's patch in r.1148503. Also included a set of tests which detect this condition.

>             Project: Qpid
>          Issue Type: Bug
>          Components: C++ Broker
>    Affects Versions: 0.10
>            Reporter: Gordon Sim
>             Fix For: 0.11
> E.g. with Error dequeuing message, persistence id not set (MessageStoreImpl.cpp:1355)
(exact error depends on store used).
> To reproduce, bind a durable queue to an exchange with a given binding key the set up
a route between that same exchange on two brokers with the 'source broker' being the one with
the durable queue bound to it. Then bind a queue on the 'destination' broker with the same
binding key as used for the durable queue. Then publish a transactional message to the source
brokers exchange with a matching routing key. The message will be enqueued on both the durable
queue and the federation routes temporary bridge queue. However the persistence id for the
message, set when enqueueing on the durable queue is lost and subsequent attempts to dequeue
to fail.
> The problem is that the copy-on-write strategy used to workaround QPID-2670 means that
the message on which the persistent store id is set is not then pushed onto the appropriate
queues, the copy is (and the copy may not have the persistence id set on it).
