AttachPoint
* LLClientView.CreateImprovedTerseBlock() now uses AttachPoint and does the proper high-low swap (this should fix disappearing attachment pieces)

packet. This is a limitation of LLUDP, nothing we can really do about it
* Marking CoarseLocationUpdate as *not* zerocoded. Zerocoding can only save space when a packet contains three or more contiguous zeroes, and will use more space if it contains single zeroes randomly scattered through the packet (which is what you see when you send a long list of UUIDs)

Applied with major changes. Core functionality commented pending review
for possible rights escalation. No user functionality yet.

now 6, as before, item limit is 5. This should avoid most, if not
all, oversized packets.

InventoryDescendents packet. Testing has shown that UDP inventory now
works flawlessly and, unlike CAPS inventory, doesn't download the entire
agent inventory on start. Neither does it incessantly re-request folder
NULL_KEY. Therefore, I have disabled CAPS inventory.

packet is a mess and shouldn't be used at all (in favor of the event queue message)
* Clean up the way we send AvatarGroupsReply packets, including clamping the group name and group title
|
|
|
|
|
|
|
| |
* Unified the way region handles are stored and used in ScenePresence
* Fixed camera position for child agents
* CheckForSignificantMovement now checks avatar and camera position (both are important for scene prioritization)
* Removing debug code from the previous commit

category to task
* Fixing a bug where the max burst rate for the state category was being set as unlimited, causing connections to child agents to saturate bandwidth
* Upped the example default drip rates to 1000 bytes/sec, the minimum granularity for the token buckets
|

* Prints a warning for any future packet splitting failures

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
|

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)
|
|
|
|
|
|
| |
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

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

* 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
|
|
|
|
| |
* Replaced calls to ThreadPool.QueueUserWorkItem() with ThreadPool.UnsafeQueueUserWorkItem() since OpenSim does not use Code Access Security sandboxing

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

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

our own avatar is ready to send
* Reduce the scope of the locks when processing the update queues
* Reuse the ImprovedTerseObjectUpdate.RegionData block
