* Cleared up much confusion in PollServiceRequestManager. Here's the history:Diva Canto2013-07-173-49/+36
| | | | | | 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.
* Revert "MSDN documentation is unclear about whether exiting a lock() block ↵Justin Clark-Casey (justincc)2013-07-161-8/+5
| | | | | | | | | | | | 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.

|/ | | | | | | | | to print various counts of capability invocation by user and by cap This currently prints caps requests received and handled, so that overload of received compared to handled or deadlock can be detected. This involves making BaseStreamHandler and BaseOutputStream record the ints, which means inheritors should subclass ProcessRequest() instead of Handle() However, existing inheriting classes overriding Handle() will still work, albeit without stats recording. "show caps" becomes "show caps list" to disambiguate between show caps commands

* Make the concept of namespaces explicit in dynamic attributesJustin Clark-Casey (justincc)2013-06-272-126/+182
| | | | | | | | This is in order to reduce the likelihood of naming clashes, make it easier to filter in/out attributes, ensure uniformity, etc. All dynattrs in the opensim distro itself or likely future ones should be in the "OpenSim" namespace. This does alter the underlying dynattrs data structure. All data in previous structures may not be available, though old structures should not cause errors. This is done without notice since this feature has been explicitly labelled as experimental, subject to change and has not been in a release. However, existing materials data is being preserved by moving it to the "Materials" store in the "OpenSim" namespace.

* Make it possible to specify display of stats in a particular 'container' by ↵Justin Clark-Casey (justincc)2013-06-202-3/+17
| | | | | | | | | separating category and container with a period. e.g. "show stats server.network" I failed to realize this had already been implemented without the period in the show stats command (as the command help had not been updated). However, I would prefer the . approach as it will allow specifying multiple stats, easier wildcarding, etc. This commit also prevents any stat from having a period in its short name.
