2009-11-04Add some length to the backet buffer for packet sending so oversizeMelanie1-1/+1
inventory packets don't make us barf
2009-11-04Add an overload to OutPacket as per jhurliman. Switch hacky workaroundMelanie1-5/+15
for InventoryDescendents to the proper way
2009-11-04Bounce the pacjet items limit back up to 6Melanie1-1/+1
2009-11-04Prevent autosplitting of inventory descendents packets. Also reduces theMelanie1-1/+4
number of items per packet to 5 to prevent asserts
2009-11-04Correctly set the totall number of descendents in inventory retrievalMelanie1-3/+4
2009-11-04Backport the fixes to WebFetchInventoryDescendents to the UDPMelanie1-152/+94
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.
2009-10-30Make the default and max RTO configurable int he linden client stackMelanie2-5/+19
2009-10-30Fixed a regression in SendAvatarGroupsReply()John Hurliman1-2/+2
2009-10-30Convert the AvatarGroupsReply message to the event queue.Melanie1-26/+39
2009-10-30Add a using for OSD to the client viewMelanie1-0/+1
2009-10-30* Disables automatic packet splitting on AvatarGroupsReply packets. This ↵John Hurliman2-14/+16
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
2009-10-30* Fix for a potential race condition in ScenePresence.AbsolutePositionJohn Hurliman1-2/+0
* 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
2009-10-30* Moving parcel media and avatar update packets from the unthrottled ↵John Hurliman4-22/+25
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
2009-10-30* Fixes issue #4329 "llDialog fails silently" by updating OpenMetaverse.dllJohn Hurliman2-10/+10
* Prints a warning for any future packet splitting failures
2009-10-29* Commented out two noisy debug lines in the LLUDP serverJohn Hurliman1-2/+2
* Misc. cleanup in ScenePresence.HandleAgentUpdate()
2009-10-28Always send a time dilation of 1.0 while we debug rubberbanding issuesJohn Hurliman1-101/+0
2009-10-28Marking ImprovedTerseObjectUpdate packets for avatars as unthrottled to testJohn Hurliman1-1/+1
2009-10-28Modified visibilities of properties and methods. This is so that SL client ↵Mikko Pallari2-12/+12
based clients can use UDP server that is inherited from LLUDPServer.
2009-10-27Experimental test to rate limit the incoming packet handler and try to ↵John Hurliman1-0/+8
always leave a worker thread available for other tasks
2009-10-27* Converts ClientManager.ForEach() (and as a result, Scene.ForEachClient()) ↵John Hurliman2-4/+6
to use a non-blocking parallel method when operating in async mode * Minor code readability cleanup
2009-10-26* Double the priority on avatar bake texture requests to get avatars rezzing ↵John Hurliman1-4/+14
in faster than the surrounding scene * Adds duplicate tracking for SceneObjectParts and ScenePresences to avoid sending out duplicate ImprovedTerseObjectUpdate packets
2009-10-26Removing the ClientManager reference from IScene and hiding it entirely ↵John Hurliman1-7/+7
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* Switched all operations on the list of clients that could be either sync ↵John Hurliman1-2/+2
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
2009-10-26ParcelObjectOwnersReplyPacket has null DataBlock when a client requests a ↵Dan Lake1-0/+4
list of their prims in the region and none exist. Instead of leaving pack.Data null, this patch sets a new DataBlock[0];
2009-10-26Changed UseCircuitCode handling to be synchronous or asynchronous depending ↵John Hurliman1-10/+21
on the async_packet_handling config option, and added a debug log message when a UseCircuitCode packet is handled
2009-10-26Removed an unnecessary lock in LLUDPClient.UpdateRTO() and ↵John Hurliman1-30/+21
LLUDPClient.BackoffRTO()
2009-10-25Changing Scene.ForEachClient to use the synchronous for loop instead of ↵John Hurliman2-16/+42
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
2009-10-23* Unregister Mono.Addins event handlers in PluginLoader.Dispose() and always ↵John Hurliman1-1/+5
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
2009-10-23Cleaning up OpenSim.ini.example for LLUDP. The [LLClient] section has been ↵John Hurliman2-13/+28
removed and several new parameters have been added to [ClientStack.LindenUDP]
2009-10-23Uncommented the resend log line so the previous commit can be seen in actionJohn Hurliman1-1/+1
2009-10-23* Changed the max RTO value to 60 seconds to comply with RFC 2988John Hurliman2-1/+4
* Implemented section 5.5, exponential backoff of the RTO after a resend
2009-10-23Commented out noisy debugging about resent packets (normal) and agents ↵John Hurliman2-3/+3
setting throttles (normal)
2009-10-23Experimental change to use an immutable array for iterating ScenePresences, ↵John Hurliman1-71/+70
avoiding locking and copying the list each time it is accessed
2009-10-22Implemented a Watchdog class. Do not manually create Thread objects anymore, ↵John Hurliman1-8/+11
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
2009-10-22Add copyright header. Formatting cleanup.Jeff Ames1-1/+1
2009-10-21* Changed the misc. methods calling ThreadPool.UnsafeQueueUserWorkItem() to ↵John Hurliman1-3/+3
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* Change the OnQueueEmpty signature to send the flags of the queues that are ↵John Hurliman4-61/+108
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* Clarified what FireQueueEmpty is doing with a MIN_CALLBACK_MS constant and ↵John Hurliman4-18/+8
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* FireQueueEmpty now checks if a measurable amount of time has passed, and ↵John Hurliman3-38/+16
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* Changed the timing calculations for sending resends/acks/pings from ↵John Hurliman3-41/+63
per-client back to per-scene * Testing a fix from Jim to make the cpu usage fix cleaner
2009-10-21Testing out a hack to identify the source of the high cpu usageJohn Hurliman1-0/+3
2009-10-21Removing the Sleep(0) call from the OutgoingPacketHandlerJohn Hurliman1-6/+3
2009-10-21* Handle UseCircuitCode packets asynchronously. Adding an agent to a scene ↵John Hurliman3-13/+49
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* Replaced the UnackedPacketCollection with a lockless implementation. The ↵John Hurliman4-208/+126
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
2009-10-21Fixed the way OnQueueEmpty is called to prevent simultaneous calls for the ↵John Hurliman1-7/+7
same category
2009-10-21Committing Jim's optimization to replace the 20ms sleep in outgoing packet ↵John Hurliman4-50/+121
handling with an interruptible wait handle
2009-10-20* Added a sanity check to GetScriptAssemblies() and GetScriptStates() for ↵John Hurliman4-0/+219
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* Removed the unused m_agentUpdates collection and some extra work that was ↵John Hurliman1-1/+1
being done for AgentUpdate packets * Start LLUDPClients unpaused (this variable is not being used yet)
2009-10-20* Removed the throttle speed optimizations to see if it brings stability backJohn Hurliman2-72/+69
* 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
2009-10-20Added try/catches in the outgoing packet handler to match the one in the ↵John Hurliman1-45/+59
incoming packet handler
