> Description of problem:
> qpid trace/logs statistics about object deletion. However some of these data are wrong.
In particular msgDepth for a queue is everytime zero (and msgTotalDequeues equals to msgTotalEnqueues
despite no consumer was subscribed to the queue), or unackedMessages for a session is zero
everytime as well.
> Version-Release number of selected component (if applicable):
> qpid 0.22
> How reproducible:
> 100%
> Steps to Reproduce:
> 1) msgDepth:0 for queue:
> echo "auth=no" > /etc/qpid/qpidd.conf
> echo "trace=yes" >> /etc/qpid/qpidd.conf
> echo "log-to-file=/tmp/qpidd.log" >> /etc/qpid/qpidd.conf
> rm -rf /var/lib/qpidd/* /tmp/qpidd.log
> service qpidd restart
> qpid-send -m 123 -a "testQueue; {create:always, delete:always}"
> sleep 10  # just to let periodic processing to run & print out the stats
> grep "Mgmt delete queue" /tmp/qpidd.log
> Actual results:
> 2013-08-29 14:05:38 [Model] trace Mgmt delete queue. id:testQueue Statistics: {acquires:123,
bindingCount:0, bindingCountHigh:0, bindingCountLow:0, byteDepth:0, byteFtdDepth:0, byteFtdDequeues:0,
byteFtdEnqueues:0, bytePersistDequeues:0, bytePersistEnqueues:0, byteTotalDequeues:0, byteTotalEnqueues:0,
byteTxnDequeues:0, byteTxnEnqueues:0, consumerCount:0, consumerCountHigh:0, consumerCountLow:0,
discardsLvq:0, discardsOverflow:0, discardsPurge:0, discardsRing:0, discardsSubscriber:0,
discardsTtl:0, flowStopped:False, flowStoppedCount:0, messageLatencyAvg:0, messageLatencyCount:0,
messageLatencyMax:0, messageLatencyMin:0, msgDepth:0, msgFtdDepth:0, msgFtdDequeues:0, msgFtdEnqueues:0,
msgPersistDequeues:0, msgPersistEnqueues:0, msgTotalDequeues:123, msgTotalEnqueues:123, msgTxnDequeues:0,
msgTxnEnqueues:0, releases:0, reroutes:0, unackedMessages:0, unackedMessagesHigh:0, unackedMessagesLow:0}
> Expected results:
> acquires:0
> msgTotalDequeues:0
> (several other counters are supposed to be wrong as well like byteFtdDequeues)
> 2) Reproducer for unackedMessages:0 for session:
> qpid-send -m 11 -a "myQueue; {create:always}"
> qpid-receive -m 100 -a "myQueue; {create:always}" -f
> (in another terminal)
> qpid-tool
> list connection
> call <ID_of_qpid-receive-connection> close
> and now check result:
> grep Tx /tmp/qpidd.log | grep session
> should return "unackedMessages:11" but returns zero.
