31dfe87570 Prevent oversized packets from crashing the LLUDP server. It will now print a friendly error message and drop the packet 2009-10-16 14:26:58 -07:00

1bd9202f24 * Simplified the prioritization packet creation code to reduce CPU usage and increase throughput. Apologies to Jim for hacking on your code while it's only halfway done, I'll take responsibility for the manual merge
* Changed LLUDP to use its own MTU value of 1400 instead of the 1200 value pulled from the currently shipped libomv

e776dfb1d7 * Changing the "clean dropped attachments" MySQL command to a using statement inside a try/catch. This statement times out for me very frequently
* More verbose logging when zerocoding fails on an outbound packet
2009-10-16 13:22:45 -07:00
John Hurliman
a18489dc9b * Change appearance packets from State to Task. This will hopefully fix the cloud issues
* Changed the throttling logic to obey the requested client bandwidth limit but also share bandwidth between some of the categories to improve throughput on high prim or heavily trafficked regions

4b75353cbf Object update prioritization by Jim Greensky of Intel Labs, part one. This implements a simple distance prioritizer based on initial agent positions. Re-prioritizing and more advanced priority algorithms will follow soon 2009-10-15 16:35:27 -07:00

df2d5a460f Replaced the update lists with a priority queue implementation in LLClientView
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.

d44b50ee46 * Removed some of the redundant broadcast functions in Scene and SceneGraph 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)

6d3d985511 * Request from lkalif to have the Sim send a coarselocationupdate for each avatar in the sim, including yourself.
* Apparently the LLClientView should have been doing this previously..      Also fixed the 'You' on the index block..   so the client doesn't display an extra green dot.
* Thanks lkalif for bringing it to our attention.

06990b074c Allow the LLUDP server to run in either synchronous or asynchronous mode with a config setting, defaulting to synchronous mode 2009-10-14 16:48:27 -07:00

82012ec4e3 * Clean up the SetThrottle() code and add a maxBurstRate parameter to allow more tweaking in the future 2009-10-14 16:21:48 -07:00
John Hurliman
1e9e9df0b3 * Switched to a plain lock for the ClientManager collections and protected the TryGetValues with try/catch instead of a lock
* Added ClientManager.ForEachSync() for operations that need to run synchronously, such as "show connections"
2009-10-14 14:25:58 -07:00

c033477d2f * Read scene_throttle_bps from the config file and use it

4b5a2f8c02 Merge branch 'htb-throttle' of ssh://opensimulator.org/var/git/opensim into htb-throttle 2009-10-14 11:44:17 -07:00
John Hurliman
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

John Hurliman
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
2009-10-13 17:33:45 -07:00
John Hurliman
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
2009-10-13 16:53:19 -07:00
John Hurliman
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)
2009-10-13 14:50:03 -07:00
John Hurliman
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
John Hurliman
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
2009-10-13 11:14:45 -07:00
John Hurliman
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>

36dcfd2b80 * Changed logic of enabling LLProxyLoginModule to follow the new style -- true/false on the name, rather than gridmode=true.
* Better error messages on Add/Remove clients.

3f78ff6ee0 Slight variation on the locking scheme: now locking always, except the ForEach, which gets a copy of the Array. I think the ForEach was the big gorilla. 2009-10-09 19:16:03 -07:00
John Hurliman
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

8231cb2231 Putting this to exactly what it was yesterday around this time, so we can do the 100-ppl load test in WP. We need to carefully play with this code in order to understand all the problems. 2009-10-09 11:32:53 -07:00

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
