Subject [jira] Created: (QPID-2482) Topic Exchange can duplicate messages.
Date Tue, 06 Apr 2010 14:42:33 GMT
Topic Exchange can duplicate messages.

                 Key: QPID-2482
                 URL: https://issues.apache.org/jira/browse/QPID-2482
             Project: Qpid
          Issue Type: Bug
          Components: C++ Broker
         Environment: Linux
            Reporter: Ken Giusti

As per Gordon's description:

If a given queue is bound to a topic exchange with multiple bindings, a message sent to that
exchange will result in a copy being enqueued for each binding that matches. This is incorrect
- each message should be enqueued once if there is any binding to the queue that matches it.

Steps to Reproduce:
1. create queue
2. bind it to amq.topic with two distinct bindings (e.g. red.* and *.herring)
3. send amq.topic a message whose routing key matches both patterns (e.g. "red.herring")
4. check the queue

Actual results:

The message is enqueued on the queue twice.

Expected results:

The message should only be enqueued on the queue once.
