* * FireQueueEmpty now checks if a measurable amount of time has passed, and ↵John Hurliman2009-10-211-32/+10

This throttles OnQueueEmpty calls where there is no callback or the callback is doing very little work * Changed HandleQueueEmpty()'s Monitor.TryEnter() calls to locks. We want to take our time in this function and do all the work necessary, since returning too fast will induce a sleep anyways

* * Replaced the UnackedPacketCollection with a lockless implementation. The ↵John Hurliman2009-10-211-9/+2
| | | | | | | tiny amount of time spent in the locks turned into a lot of time when the rest of the LLUDP implementation went lockless * Changed the timer tracking numbers for each client to not have "memory". It will no longer queue up calls to functions like ResendUnacked * Reverted Jim's WaitHandle code. Although it was technically more correct, it exhibited the exact same behavior as the old code but spent more cycles. The 20ms has been replaced with the minimum amount of time before a token bucket could receive a drip, and an else { sleep(0); } was added to make sure the outgoing packet handler always yields at least a minimum amount

* * Change Util.FireAndForget to use ThreadPool.UnsafeQueueUserWorkItem(). ↵John Hurliman2009-10-191-45/+43
| | | | | | | | | | | | | | This avoids .NET remoting and a managed->unmanaged->managed jump. Overall, a night and day performance difference * Initialize the LLClientView prim full update queue to the number of prims in the scene for a big performance boost * Reordered some comparisons on hot code paths for a minor speed boost * Removed an unnecessary call to the expensive DateTime.Now function (if you *have* to get the current time as opposed to Environment.TickCount, always use DateTime.UtcNow) * Don't fire the queue empty callback for the Resend category * Run the outgoing packet handler thread loop for each client synchronously. It seems like more time was being spent doing the execution asynchronously, and it made deadlocks very difficult to track down * Rewrote some expensive math in LandObject.cs * Optimized EntityManager to only lock on operations that need locking, and use TryGetValue() where possible * Only update the attachment database when an object is attached or detached * Other small misc. performance improvements

This fixes a deadlock on m_AgentUpdates that was blocking up the LLUDP server

| | | | | | | | | | | | | | Replaced the update lists with a priority queue implementation in LLClientView. The priority queues are based on the MinHeap implementation also included in this commit within the OpneSim.Framework namespace.

|/ / | | | | | | | | | | * OnQueueEmpty is still called async, but will not be called for a given category if the previous callback for that category is still running. This is the most balanced behavior I could find, and seems to work well * Added support for the old [ClientStack.LindenUDP] settings (including setting the receive buffer size) and added the new token bucket and global throttle settings * Added the AssetLoaderEnabled config variable to optionally disable loading assets from XML every startup. This gives a dramatic improvement in startup times for those who don't need the functionality every startup

| | | | | | | | | | | | | | | | | | property and .Clear() method * Changed the way the QueueEmpty callback is fired. It will be fired asynchronously as soon as an empty queue is detected (this can happen immediately following a dequeue), and will not be fired again until at least one packet is dequeued from that queue. This will give callbacks advanced notice of an empty queue and prevent callbacks from stacking up while the queue is empty * Added LLUDPClient.IsConnected checks in several places to prevent unwanted network activity after a client disconnects * Prevent LLClientView.Close() from being called twice every disconnect * Removed the packet resend limit and improved the client timeout check

| | | | | | | | | | | | Util.UTF8 (not all references were switched since not all OpenSim libraries reference OpenSim.Framework) * Shrinks the largest in-memory object, the LLRAW.HeightmapLookupValue struct (only used for exporting to LLRAW terrain files), to the minimum possible size. This seems to have the odd side effect of cutting the size of the two double[256,256] terrain objects in half. Possibly an alignment optimization?
