0d2e6463d7 * Minimized the number of times textures are pulled off the priority queue
* 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

e8c1e69a0d * Copied LocklessQueue.cs into OpenSim.Framework and added the .Count 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

dc11643c00 * Consolidated adding / removing ClientManager IClientAPIs to two places in Scene
* Added some missing implementations of IClientAPI.RemoteEndPoint
* Added a ClientManager.Remove(UUID) overload
* Removed a reference to a missing project from prebuild.xml

395a8680c3 * Fixed a bug where clients were being added to ClientManager twice
* Changed the ClientManager interface to reduce potential errors with duplicate or mismatched keys
* Added IClientAPI.RemoteEndPoint, which can (hopefully) eventually replace IClientAPI.CircuitCode
* Changed the order of operations during client shutdown

23a334b9f5 * Rewrote ClientManager to remove Lindenisms from OpenSim core, improve performance by removing locks, and replace LLUDPClientCollection
* Removed the confusing (and LL-specific) shutdowncircuit parameter from IClientAPI.Close()
* Updated the LLUDP code to only use ClientManager instead of trying to synchronize ClientManager and m_clients
* Remove clients asynchronously since it is a very slow operation (including a 2000ms sleep)

c893761319 * Unregister event handlers in LLUDPServer when a client logs out and disconnects
* Move ViewerEffect handling to Scene.PacketHandlers
* Removing the unused CloseAllAgents function
* Trimming ClientManager down. This class needs to be reworked to keep LLUDP circuit codes from intruding into the abstract OpenSim core code

f55b282078 Avoid checking m_clients collection twice when a UseCircuitCode packet is received 2009-10-13 11:28:08 -07:00

82ace481c9 * Broke the circular reference between LLClientView and LLUDPClient. This should speed up garbage collection on the large LLClientView objects, and also prevents handling packets for disconnected clients
* Renamed local LLUDPClient variables to udpClient to avoid naming confusion between LLUDPClient and LLClientView

3828b3c0e8 * Eliminated unnecessary parameters from LLUDPServer.SendPacketData()
* Changed PrimMesher's Quat.Identity to return <0,0,0,1> instead of <0,0,0,1.1>

29543514e6 * Changed the "Packet exceeded buffer size" log line to debug and include the packet type. This message is normal, but could be evidence of a message marked for zerocoding that probably shouldn't be
* Changing OpenSimUDPBase back to high concurrency. High concurrency mode seems to make other problems happen faster, so it's helpful for working out other bugs and will probably

a5b9971fd7 * Added a lock object for the write functions in LLUDPClientCollection (immutable != concurrent write safety)
* Allow the UDP server to bind to a user-specified port again
* Updated to a newer version of OpenSimUDPBase that streamlines the code even more. This also reintroduces the highly concurrent packet handling which needs more testing

* Deleted an old LLUDP file

e7c877407f * Continued work on the new LLUDP implementation. Appears to be functioning, although not everything is reimplemented yet
* Replaced logic in ThreadTracker with a call to System.Diagnostics that does the same thing
* Added Util.StringToBytes256() and Util.StringToBytes1024() to clamp output at byte[256] and byte[1024], respectively

387e9f7a7f * Creates Util.UTF8 and switches some references of Encoding.UTF8 to 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?

332d3eb1bb * Removed code that is no longer used with Melanie's queue callback optimization
* Moved all priority queue access to helper functions to improve reliability and readability

9b342d3e0d * Changed the flush logic to drop packets in non-transactional streams, and to not fire any "put more data in the queues" callbacks
