Pavel Moravec resolved QPID-5124.
---------------------------------
Resolution: Fixed
Fix Version/s: 0.25
Resolved by commit r1521391. Both me and Gordon checked that all other calls of
dequeueFromStore method have either direct or indirect test of message
persistency, hence no need to further fix.

> Project: Qpid
> Issue Type: Bug

> Description of problem:
> Sending+consuming transient messages to/from a durable LVQ queue raises
> "Dequeuing message with null persistence Id" journal error on producer.
> Version-Release number of selected component (if applicable):
> 0.24
> How reproducible:
> 100%
> Steps to Reproduce:
> 1. In the first terminal:
> qpid-receive -a "myLVQ; {create:always, node:{ durable:true, x-declare: {
> arguments:{'qpid.flow_stop_count':0, 'qpid.max_count':0,
> 'qpid.last_value_queue':True, 'qpid.last_value_queue_key':'qpid.LVQ_key',
> 'qpid.file_count':64, 'qpid.policy_type':'reject', 'qpid.file_size':16,
> 'qpid.flow_resume_count':0, 'qpid.flow_stop_size':0,
> 'qpid.max_size':104857600, 'qpid.flow_resume_size':0}}}}" -f -m 100000
> --print-content=no
> 2. In the second terminal:
> qpid-send -a "myLVQ" -m 1000000 --group-key=qpid.LVQ_key --group-size=10
> --content-size=100
> Actual results:
> qpid-send is disconnected by the broker with error:
> 2013-09-09 21:24:59 [Client] warning Broker closed connection: 501, Queue
> "myLVQ": Dequeuing message with null persistence Id.
> (/root/rpmbuild/BUILD/qpid-0.22/cpp/src/qpid/legacystore/MessageStoreImpl.cpp:1370)
> Expected results:
> No such error.
> Additional info:
> - everytime, the queue has these stats after the error:
> acquires:3, bindingCount:1, bindingCountHigh:1, bindingCountLow:1,
> byteDepth:100, byteFtdDepth:0, byteFtdDequeues:0, byteFtdEnqueues:0,
> bytePersistDequeues:0, bytePersistEnqueues:0, byteTotalDequeues:100,
> byteTotalEnqueues:200, byteTxnDequeues:0, byteTxnEnqueues:0, consumerCount:0,
> consumerCountHigh:0, consumerCountLow:0, discardsLvq:1, discardsOverflow:0,
> discardsPurge:0, discardsRing:0, discardsSubscriber:0, discardsTtl:0,
> flowStopped:False, flowStoppedCount:0, messageLatencyAvg:0,
> messageLatencyCount:0, messageLatencyMax:0, messageLatencyMin:0, msgDepth:1,
> msgFtdDepth:0, msgFtdDequeues:0, msgFtdEnqueues:0, msgPersistDequeues:0,
> msgPersistEnqueues:0, msgTotalDequeues:1, msgTotalEnqueues:2,
> msgTxnDequeues:0, msgTxnEnqueues:0, redirectPeer:, redirectSource:False,
> releases:1, reroutes:0, unackedMessages:0, unackedMessagesHigh:0,
> unackedMessagesLow:0
> I.e. one msg discarded due to LVQ, 2 enqueues, 1 dequeue (the discard), BUT 3
> acquires???
