a65c8cdc38 * Reduce the velocity tolerance on sending terse updates to avoid slowly drifting prims/avatars
* Added contacts_per_collision to the ODE config section. This allows you to reduce the maximum number of contact points ODE will generate per collision and reduce the size of the array that stores contact structures

cdbeb8b83b Track timestamps when terse updates were last sent for a prim or avatar to avoid floating away forever until a key is pressed (deviates from SL behavior in a hopefully good way) 2009-10-28 03:21:53 -07:00

0c466b28bb Move the calculation of time dilation from the scene to the physics engine. The scene is still the one reporting dilation so this does not break the API or remove flexibility, but it gets the calculation happening in the right place for the normal OpenSim usage. The actual calculation of physics time dilation probably needs tweaking 2009-10-27 16:24:43 -07:00

3a1ee79ee4 Finally hunted down the Parallel deadlock. Packets were being handled asynchronously (filling up the threadpool with handlers), which would turn around and try to do parallel operations on the starved threadpool. The solution for now is to disable Parallel.cs operations until we can gracefully handle parallel operations with a potentially starved threadpool 2009-10-27 02:36:57 -07:00

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

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

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

119cf80e13 Added calls to GC.AddMemoryPressure() when unmanaged memory is allocated for ODE (helps the GC make better scheduling choices), and a call to GC.Collect() right before logins are enabled for a region. Although this doesn't change actual memory usage, it improves the reported usage from OpenSim and the operating system 2009-10-26 15:52:59 -07:00

ac7ccdf7d7 * Changed the watchdog timer to improve the speed of UpdateThread(), only track threads once the first call to UpdateThread() has been made, and allow re-tracking of threads that timed out but revived later
* Added a commented out call to Watchdog.UpdateThread() in OdeScene. If it turns out that loading a large OAR file or some other operation is timing out the heartbeat thread, we'll need to uncomment it

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

2c34619aea * Changed various modules to not initialize timers unless the module is initialized. Ideally, the timers would not initialize unless the module was actually enabled, but Melanie's work on configuring module loading from a config file should make that unnecessary
* Wrapped the Bitmap class used to generate the world map tile in a using statement to dispose of it after the JPEG2000 data is created

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

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

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)

9a5e7222ce * Removing cruft left over from the conversion to the new texture sending and UDP code

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

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

ac2f98b846 * A hacky attempt at resolving mantis #4260. I think ODE was unable to allocate memory, and therefore the unmanaged wrapper call fails or worse.. there's some unmanaged resource accounting in the ODEPlugin for ODECharacter that isn't being done properly now.
* The broken avatar may not be able to move, but it won't stop simulate from pressing on now.   And, the simulator will try to destroy the avatar's physics proxy and recreate it again...    but if this is what I think it is, it may not help.

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.

4790f8576c * Replaced (possibly broken?) math for calculating the unix timestamp in MySQLAssetData with Utils.DateTimeToUnixTime()
* Disabled UpdateAccessTime() function since it was only writing zeros anyways. This gave me a significant performance improvement for startup times and avatar logins in standalone mode
* Load attachments asynchronously so avatars with lots of attachments don't have to race the timeout clock to login
