moved messages remain listed on original queue when viewing messages using JMX,
but are not actually considered to still be on the queue
----------------------------------------------------------------------------------------------------------------------------------------
Key: QPID-1941
URL: https://issues.apache.org/jira/browse/QPID-1941
Project: Qpid
Issue Type: Bug
Components: Java Broker
Reporter: Robbie Gemmell
Fix For: 0.6
When moving messages from one queue to another using the JMX interfaces, the
messages moved remain listed in the viewMessage(from, to) results of the
original queue, despite the message count being decremented and the
deleteFromTop() and clearQueue() methods not acting on them as they are
actually no longer considered part of the queue. As such, someone attempting to
'delete from top' may not be deleting the message they are expecting, if it has
previously been moved.
Steps to reproduce:
Start broker.
Start JMS Direct Consumer example.
Stop JMS Direct Consumer example.
Start JMS Direct Producer example, resulting in 11 messages being left on the
queue 'message_queue' on the 'test' virtualhost.
Using JMX (via RCP management console, or JConsole), view messages 1 to 11 on
'message' queue, which will return 11 messages as expected. Now move messages 1
to 5 to queue 'ping'. The attributes for 'message_queue' now indicate it
contains 6 messages, and 'ping' contains 5, as expected. However, viewing
messages 1 to 11 on 'message_queue' again returns all 11 messages when it
should only return messages with AMQ ID 6 to 11. Using the DeleteFromTop
operation deletes message with AMQ ID 6, which can be verified by viewing
messages 1 to 11 and discovering 6 is no longer present. Clearing
'message_queue' at this point removes messages with AMQ ID 7-11 as would
normally be expected. However, viewing messages 1 to 11 on 'message_queue'
again returns messages with AMQ ID 1 to 5 which it should not.
