John Hurliman 1c9696a9d2 Always send a time dilation of 1.0 while we debug rubberbanding issues 2009-10-28 15:11:01 -07:00
John Hurliman 587c35f6b6 Marking ImprovedTerseObjectUpdate packets for avatars as unthrottled to test 2009-10-28 02:30:16 -07:00
Mikko Pallari 8254256fe9 Modified visibilities of properties and methods. This is so that SL client based clients can use UDP server that is inherited from LLUDPServer. 2009-10-28 00:41:13 -07:00
John Hurliman f89c2cac0f Experimental test to rate limit the incoming packet handler and try to always leave a worker thread available for other tasks 2009-10-27 14:16:01 -07:00
John Hurliman c75d415648 * Converts ClientManager.ForEach() (and as a result, Scene.ForEachClient()) to use a non-blocking parallel method when operating in async mode 
* Minor code readability cleanup
 2009-10-27 00:26:56 -07:00
John Hurliman b6651ce790 * Double the priority on avatar bake texture requests to get avatars rezzing in faster than the surrounding scene 
* Adds duplicate tracking for SceneObjectParts and ScenePresences to avoid sending out duplicate ImprovedTerseObjectUpdate packets
 2009-10-26 18:22:32 -07:00
John Hurliman 0b1726b524 Removing the ClientManager reference from IScene and hiding it entirely inside Scene as an implementation detail. This will reduce programming error and make it easier to refactor the avatar vs client vs presence mess later on 2009-10-26 16:48:43 -07:00
John Hurliman 4847e62e9f * Switched all operations on the list of clients that could be either sync or async to use Scene.ForEachClient() instead of referencing ClientManager directly 
* Added a new [Startup] config option called use_async_when_possible to signal how to run operations that could be either sync or async
* Changed Scene.ForEachClient to respect use_async_when_possible
* Fixing a potential deadlock in Parallel.ForEach by locking on a temporary object instead of the enumerator (which may be shared across multiple invocations on ForEach). Thank you diva
 2009-10-26 16:33:04 -07:00
Dan Lake ad624f703d ParcelObjectOwnersReplyPacket has null DataBlock when a client requests a list of their prims in the region and none exist. Instead of leaving pack.Data null, this patch sets a new DataBlock[0]; 2009-10-26 15:14:13 -07:00
John Hurliman c04775bf68 Changed UseCircuitCode handling to be synchronous or asynchronous depending on the async_packet_handling config option, and added a debug log message when a UseCircuitCode packet is handled 2009-10-26 13:38:07 -07:00
John Hurliman 2222172afa Removed an unnecessary lock in LLUDPClient.UpdateRTO() and LLUDPClient.BackoffRTO() 2009-10-26 11:28:02 -07:00
John Hurliman 730930955a Changing Scene.ForEachClient to use the synchronous for loop instead of Parallel. This is quite possibly the source of some deadlocking, and at the very least the synchronous version gives better stack traces 
* Lock the LLUDPClient RTO math * Add a helper function for backing off the RTO, and follow the optional advice in RFC 2988 to clear existing SRTT and RTTVAR values during a backoff

* Removing the unused PrimitiveBaseShape.SculptImage parameter * Improved performance of SceneObjectPart instantiation * ZeroMesher now drops SculptData bytes like Meshmerizer, to allow the texture data to be GCed * Improved typecasting speed in MySQLLegacyRegionData.BuildShape()

* Improved the instantiation of PrimitiveBaseShape
 2009-10-25 00:40:21 -07:00
John Hurliman a41cd1d069 * Unregister Mono.Addins event handlers in PluginLoader.Dispose() and always handle PluginLoader with the using pattern. This freed up 121,634,796 bytes on my system 
* Avoid allocating an Action<IClientAPI> object every round of the OutgoingPacketHandler
* Removed unnecessary semi-colon endings from OpenSim.ini.example [InterestManagement] section
 2009-10-23 13:14:29 -07:00
John Hurliman 4c45b5fd3c Cleaning up OpenSim.ini.example for LLUDP. The [LLClient] section has been removed and several new parameters have been added to [ClientStack.LindenUDP] 2009-10-23 10:35:47 -07:00
John Hurliman 37f7277378 Uncommented the resend log line so the previous commit can be seen in action 2009-10-23 01:33:43 -07:00
John Hurliman ac0acb0296 * Changed the max RTO value to 60 seconds to comply with RFC 2988 
* Implemented section 5.5, exponential backoff of the RTO after a resend
 2009-10-23 01:33:05 -07:00
John Hurliman 53bf479bab Commented out noisy debugging about resent packets (normal) and agents setting throttles (normal) 2009-10-23 01:11:40 -07:00
John Hurliman 588361e2a2 Experimental change to use an immutable array for iterating ScenePresences, avoiding locking and copying the list each time it is accessed 2009-10-23 01:02:36 -07:00
John Hurliman b2ed348aa2 Implemented a Watchdog class. Do not manually create Thread objects anymore, use Watchdog.StartThread(). While your thread is running call Watchdog.UpdateThread(). When it is shutting down call Watchdog.RemoveThread(). Most of the threads in OpenSim have been updated 2009-10-22 12:33:23 -07:00
Jeff Ames d756fa01ae Add copyright header. Formatting cleanup. 2009-10-22 18:57:24 +09:00
John Hurliman 32ccd5bb40 * Changed the misc. methods calling ThreadPool.UnsafeQueueUserWorkItem() to Util.FireAndForget() 
* Changed Util.FireAndForget() to use any of five different methods set with async_call_method in the [Startup] section of OpenSim.ini. Look at the example config for possible values
 2009-10-21 23:03:18 -07:00
John Hurliman 6492640e72 * Change the OnQueueEmpty signature to send the flags of the queues that are empty instead of firing once per empty queue 
* Change the OnQueueEmpty firing to use a minimum time until next fire instead of a sleep
* Set OutgoingPacket.TickCount = 0 earlier to avoid extra resends when things are running slowly (inside a profiler, for example)
 2009-10-21 18:03:41 -07:00
John Hurliman 4e04f6b3a5 * Clarified what FireQueueEmpty is doing with a MIN_CALLBACK_MS constant and upped it to 30ms 
* Removed the unused PacketSent() function
* Switched UnackedPacketCollection from a SortedDictionary to a Dictionary now that the sorting is no longer needed. Big performance improvement for ResendUnacked()
 2009-10-21 17:02:55 -07:00
John Hurliman b06f258319 * FireQueueEmpty now checks if a measurable amount of time has passed, and if not it sleeps for a small amount of time. 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
 2009-10-21 16:21:08 -07:00
John Hurliman 2752a3525c * Changed the timing calculations for sending resends/acks/pings from per-client back to per-scene 
* Testing a fix from Jim to make the cpu usage fix cleaner
 2009-10-21 15:22:23 -07:00
John Hurliman 62f1bfd136 Testing out a hack to identify the source of the high cpu usage 2009-10-21 14:25:22 -07:00
John Hurliman bb4da417ad Removing the Sleep(0) call from the OutgoingPacketHandler 2009-10-21 14:03:49 -07:00
John Hurliman 7ee422a344 * Handle UseCircuitCode packets asynchronously. Adding an agent to a scene can take several seconds, and was blocking up packet handling in the meantime 
* Clamp retransmission timeout values between three and 10 seconds
* Log outgoing time for a packet right after it is sent instead of well before
* Loop through the entire UnackedPacketCollection when looking for expired packets
 2009-10-21 13:47:16 -07:00
John Hurliman 9178537e94 * Replaced the UnackedPacketCollection with a lockless implementation. The 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
 2009-10-21 11:59:48 -07:00
John Hurliman c0c845aea4 Fixed the way OnQueueEmpty is called to prevent simultaneous calls for the same category 2009-10-21 01:07:40 -07:00
John Hurliman cde47c2b3d Committing Jim's optimization to replace the 20ms sleep in outgoing packet handling with an interruptible wait handle 2009-10-21 00:18:35 -07:00
John Hurliman 45dc4e0a54 * Added a sanity check to GetScriptAssemblies() and GetScriptStates() for the case where no scripting engine is enabled 
* Added TokenBucket.cs to OpenSim, with some fixes for setting a more accurate MaxBurst value and getting a more accurate Content value (by Drip()ing each get)
 2009-10-20 18:19:17 -07:00
John Hurliman 1833c69568 * Removed the unused m_agentUpdates collection and some extra work that was being done for AgentUpdate packets 
* Start LLUDPClients unpaused (this variable is not being used yet)
 2009-10-20 15:19:19 -07:00
John Hurliman d38f33736c * Removed the throttle speed optimizations to see if it brings stability back 
* Changed the outgoing packet handler to use a real function instead of a closure and to track time on a per-client basis instead of a global basis
 2009-10-20 14:41:20 -07:00
John Hurliman d1ab11dc2a Added try/catches in the outgoing packet handler to match the one in the incoming packet handler 2009-10-20 12:43:09 -07:00
John Hurliman 99abe885c8 Fixing position/rotation/collisionplane in ObjectUpdate packets for avatars 2009-10-20 12:30:34 -07:00
John Hurliman edd393ff30 Reverting the deletion of files related to texture sending until we figure out exactly what is and isn't needed 2009-10-20 11:58:23 -07:00
John Hurliman 0a6ea33ac8 * Optimized sending of terrain data 
* Send terrain data in a spiral pattern instead of a typewriter pattern (placeholder until terrain data becomes part of the interest list management)
* Added a debug line when resent packets are being sent
 2009-10-19 18:50:31 -07:00
John Hurliman fdce1be3db * Removed OpenSim.Data.NHibernate 
* Replaced calls to ThreadPool.QueueUserWorkItem() with ThreadPool.UnsafeQueueUserWorkItem() since OpenSim does not use Code Access Security sandboxing
 2009-10-19 16:52:27 -07:00
John Hurliman 142008121e * Change Util.FireAndForget to use ThreadPool.UnsafeQueueUserWorkItem(). 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
 2009-10-19 15:19:09 -07:00
John Hurliman 233e16b99c * Rewrote the methods that build ObjectUpdate and ImprovedTerseObjectUpdate packets to fill in the data more accurately and avoid allocating memory that is immediately thrown away 
* Changed the Send*Data structs in IClientAPI to use public readonly members instead of private members and getters
* Made Parallel.ProcessorCount public
* Started switching over packet building methods in LLClientView to use Util.StringToBytes[256/1024]() instead of Utils.StringToBytes()
* More cleanup of the ScenePresences vs. ClientManager nightmare
* ScenePresence.HandleAgentUpdate() will now time out and drop incoming AgentUpdate packets after three seconds. This fixes a deadlock on m_AgentUpdates that was blocking up the LLUDP server
 2009-10-18 20:24:20 -07:00
John Hurliman 1dbbf6edb6 * Process the avatar terse update priority queue as soon as an update for our own avatar is ready to send 
* Reduce the scope of the locks when processing the update queues
* Reuse the ImprovedTerseObjectUpdate.RegionData block
 2009-10-18 03:15:36 -07:00
John Hurliman b4526a5a6d * Big performance increase in loading prims from the region database with MySQL 
* Handle the AgentFOV packet
* Bypass queuing and throttles for ping checks to make ping times more closely match network latency
* Only track reliable bytes in LLUDPCLient.BytesSinceLastACK
 2009-10-18 02:00:42 -07:00
John Hurliman a3f93cffb4 * Committing Nini.dll with the patch from #3773 applied 
* Fixing a log message typo
 2009-10-17 22:06:36 -07:00
John Hurliman fdb2a75ad3 Committing the second part of Jim Greensky @ Intel Lab's patch, re-prioritizing updates 2009-10-17 18:01:22 -07:00
John Hurliman e28ac42486 Wrapped the contents of the IncomingPacketHandler loop in a try/catch statement 2009-10-17 17:19:18 -07:00
John Hurliman c81378dc22 Changing avatar movement updates to the Task throttle category until we get finer grained prioritization of avatars vs. prims 2009-10-16 17:33:41 -07:00
John Hurliman 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
John Hurliman 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
 2009-10-16 14:17:13 -07:00
John Hurliman 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
 2009-10-16 12:20:01 -07:00
John Hurliman 06354a093d Merge branch 'master' of ssh://opensimulator.org/var/git/opensim into prioritization 2009-10-16 10:09:19 -07:00
Melanie 0487092d15 Thank you, Fly man, for plumbing the AvatarInterestsUpdate packet 2009-10-16 13:28:40 +01:00
John Hurliman 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
jjgreens 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.
 2009-10-15 15:52:53 -07:00
John Hurliman 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)
 2009-10-15 15:25:02 -07:00
Teravus Ovares (Dan Olivares) 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.
 2009-10-15 02:01:29 -04:00
John Hurliman 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
John Hurliman 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
John Hurliman c033477d2f * Read scene_throttle_bps from the config file and use it 
* Minor formatting cleanup
 2009-10-14 11:52:48 -07:00
John Hurliman 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
 2009-10-14 11:43:31 -07:00
Melanie d83ace0d3b Merge branch 'master' into htb-throttle 2009-10-14 05:10:43 +01:00
John Hurliman 4135b0c4dc * Split Task category into Task and State 
* Crude prioritization hack
 2009-10-13 19:45:38 -07:00
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
 2009-10-13 18:56:54 -07:00
John Hurliman 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
 2009-10-13 12:50:59 -07:00
John Hurliman 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>
 2009-10-13 10:38:35 -07:00
Diva Canto e3d5beebfb Better handling of missing assets. 2009-10-13 06:39:11 -07:00
Diva Canto f3d2192cd4 Better handling of missing assets. 2009-10-12 18:30:06 -07:00
Diva Canto 63ed605eba Stop the recurring texture requests for textures that truly don't exist. 2009-10-12 17:36:13 -07:00
Diva Canto c0beeb929e * Fixes http://opensimulator.org/mantis/view.php?id=4225 
* Fixes http://opensimulator.org/mantis/view.php?id=3959
* Allows for viewing inventory textures outside home grid
 2009-10-12 17:00:01 -07:00
Diva Canto 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.
 2009-10-11 10:23:16 -07:00
Diva Canto 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
 2009-10-09 16:33:50 -07:00

Diva Canto 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
Melanie 23586b69a1 Slow down the packet receiving code again after new reports of thread storms. 2009-10-09 12:17:55 +01:00
John Hurliman 76a5cae0b4 Forgot to initialize m_writeLock 2009-10-09 02:18:25 -07:00
John Hurliman a3e31cdeaf Added more debugging output to the "unrecognized source" warning 2009-10-09 02:13:21 -07:00
John Hurliman 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
 2009-10-09 01:53:06 -07:00
John Hurliman 56a27c37d3 Simplified LLUDPClientCollection from three collections down to one. This will prevent any potential problems from inconsistency between the internal collections 2009-10-08 21:51:53 -07:00
John Hurliman 3a04d706c9 Fear the lockless LLUDP implementation! 2009-10-08 17:34:51 -07:00
Diva Canto 51ea39199b Putting the lock back in TryGetValue. 2009-10-08 15:42:08 -07:00
Melanie a0dd9f4bb4 Fork UDPBase from libOMV into opensim 2009-10-08 22:25:14 +01:00

Diva Canto 68961ec092 One last attempt at tunning the locking/no locking behaviour. The previous one was too lax and made the important login packets fail. 2009-10-07 20:36:24 -07:00
Diva Canto dd80380df5 Another go at the deadlock: not locking TryGetValue, and just catch/ignore exceptions. 2009-10-07 19:45:57 -07:00
Diva Canto c71b3e730d Changed the locking mechanism, because the existing one is causing deadlocks to occur. 2009-10-07 18:54:08 -07:00
Melanie d33b6fef2b replace LLClientView with proper version 2009-10-07 04:37:12 +01:00
Melanie adc208e568 Replace LLClientView on the branch with master. UNCOMPILABLE! 2009-10-07 04:36:36 +01:00
Melanie 9618c196c2 Revert "Merging in diva's locking fixes" 
This reverts commit 832cc68513.

Diva Canto e992ca0255 Rewrote parts of the code that were double-locking different objects. This is about half of the code base reviewed. 2009-10-06 15:39:53 -07:00
