- Added a thread pool executor, that combines cached and fixed size thread pooling.
It behaves like a cached thread pool in that it reuses exising threads and removes
idle threads after a timeout, limits the maximum number of threads in the pool, but
queue additional request instead of rejecting them.
- changed existing code to use the new thread pool instead of a fixed-size thread pool in
all places that are configured with a client thread pool size.
When NettyConnection.classSSLAndChannel is called from the EventLoop,
waiting for the SSL handler to close will always take 10 seconds, because
the sslCloseFuture is from a task that is scheduled with the same
EventLoop. But since the EventLoop is a single threaded executor, it
will only be executed after the current task is completed.
Due to the single threaded nature of the EventLoop, all blocking calls
should be avoided. Therefore, I removed both awaitUninterruptibly calls
if the closing happens within an event loop tasks. As a side effect,
the annoying server log timeout warnings will go away.
Temp Queue not deleted when connection is closed.
Enable Stomp in openwire test because some test uses it.
Remove unused code in opwnwire
Wrong XA error code returned when xid is missing
(ActiveMQXAConnectionFactory.testRollbackXaErrorCode)
regression in ActiveMQSslConnectionFactoryTest (SSL related)
Changed the ActiveMQClient interface to expose global thread pools as
ExecutorService and ScheduledExecutorService interface. This is necessary
to allow injecting thread pool implementations that are not based on
ThreadPoolExecutor or ScheduledThreadPoolExecutor.
1. Changed public fields in ActiveMQClient to private and added getters.
Exposing fields for thread pool sized allow to modify them in undesired ways.
I made these fields private and added corresponding getter methods.
In addition, I renamed the field 'globalThreadMaxPoolSize'
to 'globalThreadPoolSize' to be more consistent with the
'globalScheduledThreadPoolSize' field name.
I also adapted some tests to always call clearThreadPools after
the thread pool size configuration has been changed.
2. Protect against injecting null as thread pools
ActiveMQClient.injectPools allowed null as injected thread pools.
The effect was that internal threads pools were created,
but not shutdown correctly.
Adapted code to handle -1 correctly to configure an unbounded thread pool.
In addition, I removed the capability to reconfigure the max pool size
of existing thread pools, because the global thread pool can either be
an unbounded cached pool, or a bounded fixed size pool.
These 2 kinds of pool also differ in the used blocking queue,
therefore cannot be converted into each other.
