--------------------------------
Assignee: Keith Wall
> BasicMessageProducer_0_10 contains dead and questionable code
> -------------------------------------------------------------
>
> Key: QPID-2848
> URL: https://issues.apache.org/jira/browse/QPID-2848
> Project: Qpid
> Issue Type: Bug
> Components: Java Client
> Affects Versions: M3, M4, 0.5, 0.6
> Reporter: Robbie Gemmell
> Assignee: Keith Wall
>
> In BasicMessageProducer_0_10, there is a field named _preAcquire. Its value
> is set true by default and toggled false at construction time if the given
> destination is an instance of AMQQueue.
> During the notifyMessage() method, when client side selector evaluation of
> the incoming message is performed in the checkPreConditions() method, if the
> filter indicates the message is not a match then the _preAcquire field is
> used to determine acknowledgement and/or release actions to take that would
> seem to indicate the _preAcquire field is meant to describe the session
> acquire mode. Judging this value based on the incoming destination does not
> seem correct as this is actually a property of the Session used.
> Subsequent to the above mentioned uses the _preAcquire field is also used to
> determine whether to accept the message.
> Further to the above, the code called to perform acknowledgement and releases
> is dead and can never actually execute because it too depends on the
> _preAcquire field but inverted from the previous use:
> if (_preAcquire)
> {
> ...
> acknowledgeMessage(message);
> }
> else
> {
> ...
> releaseMessage(message);
> }
> followed by:
> private void acknowledgeMessage(AbstractJMSMessage message) throws
> AMQException
> {
> if (!_preAcquire)
> {
> ...
> }
> }
> and:
> private void releaseMessage(AbstractJMSMessage message) throws AMQException
> {
> if (_preAcquire)
> {
> ...
> }
> }
