Date Wed, 19 Mar 2014 15:37:44 GMT

     [ https://issues.apache.org/jira/browse/AMQ-5089?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Gary Tully resolved AMQ-5089.
-----------------------------

       Resolution: Fixed
    Fix Version/s: 5.10.0

fix in http://git-wip-us.apache.org/repos/asf/activemq/commit/b136df17

client ack is now respected for topics subs - and counters decremented on ack rather than
on delivered ack.
expired case now has its own ack type so it can be separate from delivered ack.

> Hi,
> It is coming from: 
> http://activemq.2283324.n4.nabble.com/Inflight-Count-for-topics-not-correct-td4678407.html#a4678583
> Problem:  Inflight count is not going down for topics once consumer is disconnected or
sent acknowledgements for the messages it has received.
> For topics once inflight count is increased, it is never going back down. 
> Test Scenario: 
> When a producer and a consumer connected to the broker but consumer is little bit slow,
there will be inflight messages in the broker which are not yet acknowledged. 
> Case 1 :Now after some time when consumer acknowledged the messages, than inflight count
should decrease, but that is not happening for topics.
> Case 2 :Now If at this point of time, I stop consumer broker should make inflight count
to '0' because those messages are not inflight now. (for queue these are now held messages
and for topic those messages are dropped). But when I check in Jconsole, I found that: for
a queue it is working fine and going down to 0 but for topics inflight count is not changing.
> Test Case: I tested with normal java consumer subscribing to a topic, I put thread.sleep(5000)
while receiving messages. Now consumer will take time to acknowledge messages which are received.
So that we can see inflight messages. 
> Now after 5 seconds, consumer has received the messages and also sent acknowledgement
to the broker but inflight count is not decreasing. Now if I disconnects consumer inflight
count should go down to '0', again here also it is not changing for that topic.
> Thanks,
> Anuj
