Gordon Sim commented on QPID-3487:
----------------------------------
I believe the correct fix here is to ensure the broker cleans up delivery
records for any ended transfers as and when the subscription is cancelled.
There is no need to keep them around pending completion as credit tracking is
no longer a concern. This also fixes the possibility at present of having
delivery records get 'stuck' in the list, never completed as the consumer is
cancelled.

> Key: QPID-3487
> URL: https://issues.apache.org/jira/browse/QPID-3487
> Project: Qpid
> Issue Type: Bug
> Components: C++ Client
> Reporter: Andy Goldstein
> Fix For: 0.13
>
>
> When closing a receiver for a queue that is either delete:always or
> auto-delete:true, it is possible for the queue to remain visible in
> management (qmf) even though the client has already acknowledged, released,
> or rejected all messages.
> Steps to reproduce:
> 1) Create receiver e.g. my-queue; {create:always, delete:always, node:
> {x-declare: {auto-delete: true}}}
> 2) Set capacity to something e.g. 10
> 3) Send messages to my-queue
> 4) Call get() on the receiver for each message
> 5) Ack/release/reject each message
> 6) Close the receiver
> 7) IMPORTANT: keep the session alive
> Expected results: "qpid-stat -q" will not show my-queue in the list
> Actual results: "qpid-stat -q" shows my-queue in the list
> This happens because the broker has instances of DeliveryRecord in memory for
> each message that the receiver acquired, and each DeliveryRecord has a
> shared_ptr to the Queue. Because the receiver does not necessarily send
> completions for all the message.transfer commands, DeliveryRecords will still
> be around, which means the Queue will still be visible via management.
