Ron Sigal commented on JBREM-641:
---------------------------------
A new blocking form of pull callbacks has been implemented. In nonblocking mode,
ServerInvokerCallbackHandler.getCallbacks() will immediately return as many callbacks as
it has available, possibly 0. In blocking mode, if getCallbacks() finds that no callbacks
are currently available, it will wait for some configured amount of time for a callback to
be created. If a callback is created before the time expires, it will return that
callback. If the time expires before any callbacks are created, it will return an empty
list.
There are relevant two parameters that can be configured, and a variety of ways of
configuring them. The first parameter is ServerInvoker.BLOCKING_MODE (actual value
"blockingMode"), which can be set to one of two values: ServerInvoker.BLOCKING
(actual value "blocking") and ServerInvoker.NON_BLOCKING (actual value
"nonblocking"). The blocking mode for pull callbacks is configured on a per
invocation basis, passing ServerInvoker.BLOCKING_MODE in the Client.getCallbacks()
metadata map. The default value is "nonblocking". Blocking pull callbacks can
also be used in the context of polled callbacks by
org.joss.remoting.callback.CallbackPoller. In this case, blocking mode is configured by
passing ServerInvoker.BLOCKING_MODE in the Client.addListener() metadata map. The default
value used by CallbackPoller is "blocking".
The other parameter is ServerInvoker.BLOCKING_TIMEOUT (actual value
"blockingTimeout), which determines how long
ServerInvokerCallbackHandler.getCallbacks() will wait for the creation of a callback. The
default value is 5000 milliseconds, which may be overridden in two ways.
ServerInvoker.BLOCKING_TIMEOUT may be added to the Client.addListener() metadata map, and
the associated value will become the default timeout for subsequent blocking mode pull
callbacks. Also, a per invocation value may be configured by putting
ServerInvoker.BLOCKING_TIMEOUT in the Client.getCallbacks() metadata map.
Unit test: org.jboss.test.remoting.callback.pull.blocking.BlockingPullCallbackTestCase.

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.

---------------------------------
A blocking mode CallbackPoller thread has been added to
org.jboss.test.remoting.shutdown.AbstractClient, which is used in the unit tests that
verify that there are no Remoting threads that prevent a JVM from shutting down.

Ron Sigal commented on JBREM-641:
---------------------------------
Added a new constant to org.jboss.remoting.Client: THROW_CALLBACK_EXCEPTION (actual value
"throwCallbackException"). If key THROW_CALLBACK_EXCEPTION is placed in the
metadata map passed to Client.getCallbacks(), and has a value of "true", then if
the InvokerCallbackHandler argument is not registered, getCallbacks() will throw an
exception instead of returning null. THROW_CALLBACK_EXCEPTION is used by
org.jboss.remoting.callback.CallbackPoller in blocking mode. If the call to
Client.getCallbacks() results in an exception due to the InvokerCallbackHandler not being
registered, CallbackPoller will shut down.

---------------------------------
The default polling mode in CallbackPoller has been changed to nonblocking. This way, no
changes should be experienced without explicit configuration changes.

---------------------------------
Now that it is possible to configure ConnectionValidator timeouts (see JBREM-755), it is
possible to avoid phantom timeouts. In particular, the JBossMessaging stress tests with
the http transport pass if the timeout is suitably increased.
