Timothy Bish updated AMQCPP-543:
--------------------------------
Component/s: Openwire
Priority: Minor (was: Major)
Issue Type: New Feature (was: Bug)
> message producer send never blocking when using producer flow control
> ---------------------------------------------------------------------
>
> Key: AMQCPP-543
> URL: https://issues.apache.org/jira/browse/AMQCPP-543
> Project: ActiveMQ C++ Client
> Issue Type: New Feature
> Components: Openwire
> Affects Versions: 3.8.2
> Reporter: Christian Mamen
> Assignee: Timothy Bish
> Priority: Minor
>
> For testing,
> message producer is set to non-persisted mode, with the connection producer
> window size to 1MB. (the broker enables the producer flow control and set the
> memory limit to ~10MB with vm only storage)
> I notice that when i don't have any message consumer, the broker notify me
> that the memory limit is reached, that the producer will be throttled (as i
> would expect), however the producer never blocks on a send, as if the window
> size has no effect.
> while digging into ActiveMQProducerKernel.cpp,
> I notice the private member memoryUsage (auto_ptr) is never initialized. and
> there's a TODO in the code ?
> {code}
> ActiveMQProducerKernel::ActiveMQProducerKernel(
> [...]
> // TODO - Check for need of MemoryUsage if there's a producer Windows size
> // and the Protocol version is greater than 3.
> }
> {code}
> I tried initializing the memoryUsage, and producer seem to block as expected
> on a send, when the limit is reached.
> {code}
> ActiveMQProducerKernel::ActiveMQProducerKernel(
> [...]
> // TODO - Check for need of MemoryUsage if there's a producer Windows size
> // and the Protocol version is greater than 3.
> if (session->getConnection()->getProducerWindowSize()) {
> this->memoryUsage.reset( new
> MemoryUsage(session->getConnection()->getProducerWindowSize()) );
> }
> }
> {code}
> I'm not sure what is the proper fix,
