Subject [jira] [Resolved] (AMQ-4285) NetworkFailoverTest failing
Date Thu, 31 Jan 2013 14:21:12 GMT

     [ https://issues.apache.org/jira/browse/AMQ-4285?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Gary Tully resolved AMQ-4285.
-----------------------------

    Resolution: Fixed
      Assignee: Gary Tully

it looks better now.

there are a bunch of pitfalls of request/reply with temps over a network.

temps are not persistent and are tied to the connection that creates them so  failures can
occur when a connection fails.

some appropriate mods to the test

- backup=false in failover - otherwise there is a race between failover restore and broker
teardown of the old connection.
 -- we can loose a replayed temp dest, if it arrives before the remove is complete.

- Broker.setCacheTempDestinations - this helps with reply that occur before the destination
is removed during failover. the cache keeps the message (a form of temp persistence)

- tracking DestinationDoesNotExistException - a reply may fail if it occurs during failover
recovery

- tracking dlq due to failed forwards that result from DestinationDoesNotExistException

> The test case NetworkFailoverTest is failing most times on my machine, will fail more
often if the message count value is increased.
