decoded to allow garbage collection on it
|

* 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
|
|
* Fixing a log message typo

re-prioritizing updates
|
|
|
|
Thank you, Fly-Man
|
|
relogging.
|
|
scenepresence that there was an issue so it doesn't try to make the capsule again. I have a feeling that this is some kind of object leak. We'll know for sure.. soon.
|

finer grained prioritization of avatars vs. prims
|
|
RegionLoaded() a two line function
|
|
a friendly error message and drop the packet
|
|
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

statement inside a try/catch. This statement times out for me very frequently
* More verbose logging when zerocoding fails on an outbound packet
|
|
|
|
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
|

it will definitely get us closer to the root cause.

prioritization scheme

RemoveFromPhysicalScene or we'll be leaking

debugging easier. Without this, from the user's perspective.. they cannot move, fly or otherwise do anything physical and without a message on the console, it would be hard to tell that this is what is occurring.
|

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.

implements a simple distance prioritizer based on initial agent positions. Re-prioritizing and more advanced priority algorithms will follow soon
|

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.
|
|
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)
|
|
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.

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
|
|
don't crash. This code needs to be removed as soon as user services is refactored.
|
|
with a config setting, defaulting to synchronous mode
|
|
more tweaking in the future
|
|
the TryGetValues with try/catch instead of a lock
* Added ClientManager.ForEachSync() for operations that need to run synchronously, such as "show connections"
|
|
tracked IClientAPIs
|
|
* Minor formatting cleanup
|
|
* 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

* Crude prioritization hack
|

During the heartbeat loop, Update() is called on every SceneObjectGroup which in turn checks if any SceneObjectPart has changed. For large regions (> 100k prims) this work consumes 20-30% of a CPU even though there are only a few objects updating each frame.
There is only one other reason to check every object on every frame, and that is the case where a script has registered the object with an "at target" listener. We can easily track when an object is registered or unregistered with an AtTarget, so this is not a reason to check every object every heartbeat.
In the attached patch, I have added a dictionary to the scene which tracks the objects which have At Targets. Each heartbeat, the AtTarget() function will be called on every object registered with a listener for that event. Also, I added a dictionary to SceneGraph which stores references to objects which have been queued for updates during the heartbeat. At each heartbeat, Update() is called only on the objects which have generated updates during that beat.

* There's a slight chance that this could cause a problem with regular prim crossings.. but hopefully not. Revert if it does.

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
|
|
Scene
* Added some missing implementations of IClientAPI.RemoteEndPoint
* Added a ClientManager.Remove(UUID) overload
* Removed a reference to a missing project from prebuild.xml
|
|
* 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
|
|
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)
|
|
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
|

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
|
|
* Changed PrimMesher's Quat.Identity to return <0,0,0,1> instead of <0,0,0,1.1>
