[jira] Commented: (QPID-2193) Allow deleting the first message on a queue through the JMX Management Console when connected to older brokers

This was not exposed in the updated console due for release with 0.6 (where the broker now does support deletion of arbitrary messages). This decision was made because by its very nature the method cannot guarantee which message would be deleted when it is executed, as any queue activity could alter which message is at the head of the queue. However, users may have come to expect this method to be present, and so it should be exposed for older brokers that lack the ability to exactly specify which messages should be deleted. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. - Apache Qpid - AMQP Messaging Implementation Project: http://qpid.apache.org Use/Interact: mailto:dev-subscr...@qpid.apache.org

If we can't guarantee which message is going to be deleted, or even detect which one we're going to delete I don't think we should offer this. Just because we've always let people shoot their foot off in the past doesn't mean we should continue to do so. If they really, really to keep doing that they can always use an older release.

It is only unsafe if the queue contents are changing in ways you cannot predict while you perform the operation. A better analogy might be that previously we allowed you to take aim but don't protect you from involuntary movements of your foot placing your toes in the line of fire immediately before you pulled the trigger. versions after 0.6 allow for an automatic targeting system which is guaranteed to avoid podiatric injury.
