-----------------------------------
Summary: durable LVQ raises journal error when only transient
messages are sent
Key: QPID-5124
URL: https://issues.apache.org/jira/browse/QPID-5124
Project: Qpid
Issue Type: Bug
Components: C++ Broker
Affects Versions: 0.24
Reporter: Pavel Moravec
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???
