Subject [jira] [Commented] (QPID-3521) failover process for the 0-8 client does not clear the pre-dispatch queue
Date Thu, 06 Aug 2015 10:25:05 GMT

    [ https://issues.apache.org/jira/browse/QPID-3521?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14659808#comment-14659808
] 

Keith Wall commented on QPID-3521:
----------------------------------

A couple of comments:

# What is the rationale behind taking of AllConnectionAndSessionLocks for failover on the
0-10 and 0-8..0-91 paths?   I think it would be useful to write this down (on this Jira).
# We have a plethora on 'clean' dispatch queue type methods building up on AMQSession - some
exclusively for 0-10 and some for 0-8..0-91 and these contribute to making the code hard to
fathom.  I wonder if this methods should be pushed down to the respective subclasses?  (Sorting
this out properly is beyond the scope of the Jira).

> 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.
