[jira] Created: (QPID-1660) Consumer with no credit can cause
messages not to be seen by other consumers on that queue
Consumer with no credit can cause messages not to be seen by other consumers on that queue
------------------------------------------------------------------------------------------
Key: QPID-1660
URL: https://issues.apache.org/jira/browse/QPID-1660
Project: Qpid
Issue Type: Bug
Components: C++ Broker
Affects Versions: M4
Reporter: Gordon Sim
Assignee: Gordon Sim
Fix For: M5
Create a queue and publish one message to it. Then start a consumer (pre-acquiring subscription), with credit for one message. When the message is delivered, sleep for a short while and start a new consumer on the same queue. Then have the first consumer release the message.
The released message is now available for redelivery. Unfortunately the first consumer is picked as the consumer to be notified of this. That consumers connection then attempts to deliver the message but finds it has insufficient credit. The second consumer however is not notified and the broker does not attempt to dispatch the message.
(This is a bug introduced by the change in r721685 which was intended to fix QPID-1280).
