Subject [jira] [Commented] (AMQ-4656) Pending Queue Counter is incorrect when using durable topics
Date Wed, 07 Aug 2013 14:40:48 GMT

    [ https://issues.apache.org/jira/browse/AMQ-4656?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13732058#comment-13732058

Dejan Bosanac commented on AMQ-4656:
------------------------------------

The first stab at fixing this is in svn revision 1511333. I changed the way keepDurableSubsActive
works, by not stopping/starting the cursor when subscription (de)activates. This is a natural
way in how this feature should work and also simplifies things a bit.



I verified the fix by running all tests with that has durable in the name, but we should wait
for the full nightly build to see if something is broker.

> When using a durable topics the Pending Queue Counter provides an incorrect value for
pending messages.
> Steps to recreate
> Set up the durable subscriber
> {noformat}
> ant consumer -Durl=tcp://localhost:61616 -Dtopic=true -Dsubject=MYSUB -Ddurable=true
-Dmax=2
> {noformat}
> Stop the subscriber
> Send 20 persistent messages
> {noformat}
> ant producer -Ddurable=true -Durl=tcp://localhost:61616 -Dtopic=true -Dsubject=MYSUB
-Dmax=20
> {noformat}
> Consume 2 messages
> {noformat}
> ant consumer -Durl=tcp://localhost:61616 -Dtopic=true -Dsubject=MYSUB -Ddurable=true
-Dmax=2
> {noformat}
> View the counter stats.
> The result is the following:
> {noformat}
> Pending Queue Size = 38
> Dispatched Queue Size = 0
> Dispatched Counter = 20
> Enqueue Counter = 20
> Dequeue Counter = 2
