Fix bug in synchronizing over ProcedureEvent

    Details

    • Type: Bug
    • Status: Resolved
    • Priority: Major
    • Resolution: Fixed
    • Affects Version/s: None
    • Fix Version/s: 2.0.0-beta-1
    • Component/s: None
    • Labels:
      None

      Description

      Following synchronizes over local variable rather than the original ProcedureEvent object. Clearly a bug since this code block won't follow exclusion with many of the synchronized methods in ProcedureEvent class.

       @Override
        public void wakeEvents(final int count, final ProcedureEvent... events) {
          final boolean traceEnabled = LOG.isTraceEnabled();
          schedLock();
          try {
            int waitingCount = 0;
            for (int i = 0; i < count; ++i) {
              final ProcedureEvent event = events[i];
              synchronized (event) {
                if (!event.isReady()) {

          Two of the three ProcedureEvent functions in ProcedureScheduler don't even use scheduler in any way - waitEvent and suspendEvent. They only work on event's internals. There's no reason to put them in scheduler. Moving them to PEvent class.
          On the same lines, am making ProcedureEvent class to be entry point for waking up events (just like all PEvent related functions).

          ProcedureScheduler doesn't "own" events i.e. it doesn't keep track of events, or manage them, or anything. So we shouldn't put ProcedureEvent "utility" functions in ProcedureScheduler.

          The test TestHRegionWithInMemoryFlush extends TestHRegion which is flaky. But TestHRegionWithInMemoryFlush itself doesn't appear in flaky list, so i ran it 10 times locally and it passed all the times.
          Fixed all 3 checkstyle errors.
          Committing to master and branch-2.
          Thanks for the review stack.
