* Replaced the update lists with a priority queue implementation in LLClientViewjjgreens2009-10-151-45/+179
| | | | | | | 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. Initially setup to exactly mimic the behavior beofre the change which was a first come first serve queue.
* * Removed some of the redundant broadcast functions in Scene and SceneGraph ↵John Hurliman2009-10-151-1/+228
| | | | | | | | so it is clear who/what the broadcast is going to each time * Removed two redundant parameters from SceneObjectPart * Changed some code in terse update sending that was meant to work with references to work with value types (since Vector3 and Quaternion are structs) * Committing a preview of a new method for sending object updates efficiently (all commented out for now)
* Allow the LLUDP server to run in either synchronous or asynchronous mode ↵John Hurliman2009-10-142-6/+29
| | | | with a config setting, defaulting to synchronous mode
* * Clean up the SetThrottle() code and add a maxBurstRate parameter to allow ↵John Hurliman2009-10-143-97/+155

* * Switched to a plain lock for the ClientManager collections and protected ↵John Hurliman2009-10-141-1/+3
| | | | | | the TryGetValues with try/catch instead of a lock * Added ClientManager.ForEachSync() for operations that need to run synchronously, such as "show connections"
* * Read scene_throttle_bps from the config file and use itJohn Hurliman2009-10-142-10/+5

* | | * Minimized the number of times textures are pulled off the priority queueJohn Hurliman2009-10-147-67/+141
|/ / | | | | | | | | | | * 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

* | * Unregister event handlers in LLUDPServer when a client logs out and ↵John Hurliman2009-10-132-239/+221
