Previously, the alternate exchange attribute of a queue was not accessible via QMF. The alternate exchange was not visible in either qpid-config or in qpid-tool. The queue did have an alternate exchange and behaved correctly, however it was simply invisible through QMF. With this update, the queue is accessible via QMF as expected.

Description Ted Ross 2009-10-28 18:30:27 UTC 
Description of problem:

The alternate exchange attribute of a queue is not accessible via QMF.

Version-Release number of selected component (if applicable):

1.1.6 / 1.2

How reproducible:

100%

Steps to Reproduce:
1. qpid-config add queue queue-name --alternate-exchange amq.fanout
2. qpid-config queues
3. View the queue using qpid-tool
  
Actual results:

The alternate exchange is not visible in either qpid-config or in qpid-tool.  The queue does have an alternate exchange and behaves correctly, it is simply invisible through QMF.

Expected results:

Expect to see "amq.fanout" in both tools.

Additional info:

Note that this is a model deficiency.  The QMF schema for broker queues does not have an altExchange property.  Once this is fixed, qpid-config will need to be updated to recognize and display this attribute.
Comment 1 Nuno Santos 2009-10-28 19:12:25 UTC 
There is actually a altExchange property in the schema, it just wasn't tagged as a reference. I fixed that on 9/15, at svn rev 815449 (see below). But qpid-config may still need to be updated.

Comment 2 Ted Ross 2009-10-28 19:25:19 UTC 
The update in revision 815449 affects the "exchange" class.  This bug is about the "queue" class which needs an altExchange property but doesn't have one.

Fixed upstream at revision 831351.
Comment 6 Jiri Kolar 2010-09-20 14:03:55 UTC 
This is not visible on 1.2 as --alternate-exchange does not exist in qpid-config 1.2. Newer version have to be used to reproduce this.

fixed on qpid-tools-0.7.946106-10 alternate exchange shown.
