Subject [jira] [Commented] (QPID-3521) failover process for the 0-8 client does not clear the pre-dispatch queue
Date Tue, 04 Aug 2015 09:12:04 GMT

    [ https://issues.apache.org/jira/browse/QPID-3521?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14653332#comment-14653332

Alex Rudyy commented on QPID-3521:
----------------------------------

Keith,
I raised JIRA [QPID-6677|https://issues.apache.org/jira/browse/QPID-6677] to address your
comment #1.
Regarding comment #2: The test does not only test stop functionality. The primary purpose
of it is to make sure that pre-dispatch queue with messages is drained regardless whether
dispatcher stopped or not.
I could not figure out the better way to make sure that messages are prefetched and have not
get into the consumers queues. For that purpose, I stopped the queue from a dispatcher thread.
Regarding comment #3: I fill made the change to address pointed issue.
Regarding comment #4: I will implement the fix. It seems we got the separate JIRA about the
issue [QPID-3520|https://issues.apache.org/jira/browse/QPID-3520]. It make sense to do as
part of JIRA [QPID-3520|https://issues.apache.org/jira/browse/QPID-3520].

> failover process for the 0-8 client does not clear the pre-dispatch queue, only the consumer
receive queue.
> This is currently masked by an issue with the rollbackMark. The changes made in QPID-3546
to fix the 0-10 client path need to be applied to the 0-8/9/9-1 client path when this issue
is resolved.
