[jboss-jira] [JBoss JIRA] Commented: (JBREM-641) re-implement the callback polling for http transport to reduce latency

[Ron Sigal (JIRA)]

    [ http://jira.jboss.com/jira/browse/JBREM-641?page=comments#action_12364644 ] 
            
Ron Sigal commented on JBREM-641:
---------------------------------

CallbackPoller synchronizes the shutdown process so that CallbackPoller.stop() will not return until (1) Client.getCallbacks() has returned, (2) all retrieved callbacks have been passed to the application, and (3) and acknowledgements have been sent.  In blocking mode, though, waiting for  Client.getCallbacks() to return could be very time consuming - several seconds, for example.  CallbackPoller has a new parameter, configurable by passing in CallbackPoller.SYNCHRONIZED_SHUTDOWN (actual value "doSynchronizedShutdown").  In a synchronized shutdown, CallbackPoller.stop() will wait for Client.getCallbacks() to return, and in an unsynchronized shutdown, it will not.

In blocking mode, the default is to do an unsynchronized shutdown, and in nonblocking mode, the default is to do a synchronized shutdown.

> Per forum thread, would be nice to have a more "real-time" way to get callbacks from server when using http transport so don't have to wait on ping period.
