* Cleared up much confusion in PollServiceRequestManager. Here's the history:Diva Canto2013-07-171-1/+1
| | | | | | When Melanie added the web fetch inventory throttle to core, she made the long poll requests (EQs) effectively be handled on an active loop. All those requests, if they existed, were being constantly dequeued, checked for events (which most often they didn't have), and requeued again. This was an active loop thread on a 100ms cycle! This fixes the issue. Now the inventory requests, if they aren't ready to be served, are placed directly back in the queue, but the long poll requests aren't placed there until there are events ready to be sent or timeout has been reached. This puts the LongPollServiceWatcherThread back to 1sec cycle, as it was before.
* minor: Add warning method doc about possibly inconsistent results returned ↵Justin Clark-Casey (justincc)2013-07-161-1/+19

* Revert "Revert "MSDN documentation is unclear about whether exiting a lock() ↵Justin Clark-Casey (justincc)2013-07-161-5/+8
| | | | | | | | | | | block will trigger a Monitor.Wait() to exit, so avoid some locks that don't actually affect the state of the internal queues in the BlockingQueue class."" This reverts commit 21a09ad3ad42b24bce4fc04c6bcd6f7d9a80af08. After more analysis and discussion, it is apparant that the Count(), Contains() and GetQueueArray() cannot be made thread-safe anyway without external locking And this change appears to have a positive impact on performance. I still believe that Monitor.Exit() will not release any thread for Monitor.Wait(), as per http://msdn.microsoft.com/en-gb/library/vstudio/system.threading.monitor.exit%28v=vs.100%29.aspx so this should in theory make no difference, though mono implementation issues could possibly be coming into play.

| | | | | | | | | | | | will trigger a Monitor.Wait() to exit, so avoid some locks that don't actually affect the state of the internal queues in the BlockingQueue class." This reverts commit 42e2a0d66eaa7e322bce817e9e2cc9a288de167b Reverting because unfortunately this introduces race conditions because Contains(), Count() and GetQueueArray() may now end up returning the wrong result if another thread performs a simultaneous update on m_queue. Code such as PollServiceRequestManager.Stop() relies on the count being correct otherwise a request may be lost. Also, though some of the internal queue methods do not affect state, they are not thread-safe and could return the wrong result generating the same problem lock() generates Monitor.Enter() and Monitor.Exit() under the covers. Monitor.Exit() does not cause Monitor.Wait() to exist, only Pulse() and PulseAll() will do this Reverted with agreement.

| | | | | | | Fixing LLClientView memory leak by disposing of all timers utilized in LLClientView as they contain references to the callback method. This required the use of the Terminate and Close infrastructure that was already in place but was not being utilized.
