[jira] [Commented] (QPID-5735) The Selector property amqp.redelivered is not computed correctly

["Andrew Stitcher (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/QPID-5735?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13986281#comment-13986281 ] 

Andrew Stitcher commented on QPID-5735:
---------------------------------------

I don't think that is referring to the same thing at all. The delivery-count this is about is defined in section 3.2.1 of the Amqp 1.0 spec (Message Headers) not 2.6.7 or 2.7.4 (link flow control)

> Due to the fix for QPID-4668. The delivery-count held by a queued message is now off by 1 such that redelivered should actually be delivery-count>=0. This is because the count will be adjusted after the selector runs but before any actual delivery.
> You can replicate this with qpid-send/qpid-receive:
> {code}
> qpid-send -a "q; {create:always}" 
> {code}
> Then get message without acknowledging:
> {code}
> qpid-receive -a q --print-headers yes --ack 0
> {code}
> [One message is received with no Redelivered header]
> now get message with selector
> {code}
> qpid-receive -a "q; {link:{selector:amqp.redelivered=true}" --print-headers yes --ack 0
> {code}
> [No messages are received even though there is a redelivered message]
