[jboss-jira] [JBoss JIRA] Updated: (JBMESSAGING-381) Add param on destination to disable persistence

[Jeff Mesnil (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBMESSAGING-381?page=all ]

Jeff Mesnil updated JBMESSAGING-381:
------------------------------------

    Attachment: patch-JBMESSAGING-381.txt

tentative patch.

corresponding test case is:
export TARGET_CLASS=org.jboss.test.messaging.jms.PersistenceTest
export TARGET_TEST=testQueueWithDisabledPersistence

test case is:
* deploy a queue with disabled persistence
* send a few messages with DeliveryMode.PERSISTENT
* restart the server
* redeploy the same queue
* check that the queue is empty

(the opposing test is PersistenceTest.testQueuePersistence() which checks
that the messages are still in the queue after restart)

- Persistent is true by default for destinations.
- It can be set only before the destination is started (at deployment time)
- a "not persistent" destination corresponds to a MessagingQueue w/o a 
  PersistenceManager and flagged as non recoverable

I did not check passing null as a PersistenceManager in ChannelSupport is acceptable... it may generate unexpected NPE...

> We should add a configuration param on destinations which id true prevents messages being persisted even if they are persistent.
> This should give equivalent functionality to the JBossMQ NullPersistenceManager.
> in some circumstances uses want to override persistence for messages but have no access to change the delivery mode at the sender.
