[jira] [Commented] (QPID-3481) Acquired messages are not sent to alternate exchange when queue is deleted and receiver's session closed

    [ https://issues.apache.org/jira/browse/QPID-3481?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13103565#comment-13103565 ] 

Gordon Sim commented on QPID-3481:
----------------------------------

Deleting a queue before you have released or accepted any messages from it is an odd thing to do in my opinion. However the 0-10 specification states 'When a queue is deleted any pending messages are sent to the alternate-exchange if defined, or discarded if it is not.'

The correct fix therefore is to reroute the messages at the point of deletion. My advice would be to avoid deleting a queue in this state if at all possible.

> Currently, the broker will lose messages in the following scenario:
> 1. Client creates receiver to a queue (queue has an alternate exchange configured)
> 2. Client acquires message from queue
> 3. Client closes receiver (with delete:always or delete:receiver)
> 4. Client closes session
> We expect that the messages should be sent to the now-deleted queue's alternate exchange if/when they are released.
> Messages are not sent to the alternate exchange immediately upon closure of the receiver because the client still has acquired messages; this is fine, but when the client either releases the messages or closes the session, these messages should be sent to the alternate exchange.
