2010-07-17Ensure that packets do NOT get delivered to a client before the modules that ↵Tom Grimshaw1-1/+22
can deal with the client's response have finished loading.
2010-07-17Revert 233c872.. "* Call client.Start() sunchronously. Calling thos async ↵Tom Grimshaw1-10/+1
avoids some stuttering", pending fix for the core issue
2010-07-02Call client.Start() sunchronously. Calling thos async avoids some stutteringMelanie Thielker1-1/+10
when people log in, but fatally screws up money.
2010-05-17Following on from the last commit, the stop/disconnect packet should NOT be ↵Tom Grimshaw1-1/+1
sent when the user logs out. This eliminates the annoying "crash on log out" bug, and allows the client to commit important information at the last moment (attachment data!)
2010-05-12* Initial commit of the slimupdates2 rewrite. This pass maintains the ↵unknown1-14/+4
original behavior of avatar update sending and has a simplified set of IClientAPI methods for sending avatar/prim updates
2010-05-11Spin the AddNewClient process off into a new thread to avoid locking up the ↵Tom Grimshaw1-1/+2
LLUDPServer (and therefore the entire scene)
2010-04-02Don't append ACKs to zerocoded packets. Although this should fine in theory, ↵John Hurliman1-15/+20
I'm seeing the viewer ignore or fail to parse ACKs appended to our zerocoded packets. This should cut down on viewer->sim resend traffic
2010-03-16Removed the unused use_async_when_possible config variableJohn Hurliman1-1/+1
2010-02-23Streamlined error logging for malformed packets and fixed a bug when ↵John Hurliman1-4/+3
printing the hex dump
2010-01-29* HGGridConnector is no longer necessary.Diva Canto1-0/+3
* Handle logout properly. This needed an addition to IClientAPI, because of how the logout packet is currently being handled -- the agent is being removed from the scene before the different event handlers are executed, which is broken.
2010-01-28HG 1.5 is in place. Tested in standalone only.Diva Canto1-20/+0
2010-01-18Go Home works. With security!!Diva Canto1-0/+20
2009-12-20Reverted my changes to jhurliman's packet stack since it currently causes ↵CasperW1-24/+3
more problems than it resolves. The stack DOES need a rework particularly with regards to priorities, but this is not it.
2009-12-13* Add some glue that allows LocalPacketHandlers to decide if they want the ↵Teravus Ovares (Dan Olivares)1-1/+1
packet to be processed asynchronously or not. * Make several packets not asynchronous (such as AgentUpdate). In theory, all fast returning packet handling methods should not be asynchronous. Ones that wait on an external resource or a long held lock, should be asynchronous.
2009-12-06Revert "Make ObjectSelect packet processing not use FireAndForget"Melanie1-6/+1
This reverts commit cade14c58c335503221753b10ec361898ce5f9d4.

2009-11-21Improved avatar responsiveness.CasperW1-11/+13
2009-11-15- Lower TIME_MS_TOLERANCE to 200ms - Allow m_updateFlag to be reset to 0 in ↵unknown1-2/+22
the event of a terse update being rejected - Re-add a synchronous SendTo for certain types of packets
2009-11-05Applying #4332, optional packet statistics loggingJohn Hurliman1-0/+111
2009-11-04Refine oversized packet handling as per jhurliman. Reallocate the buffer toMelanie1-4/+7
actual packet size only for oversized packets.
2009-11-04Add some length to the backet buffer for packet sending so oversizeMelanie1-1/+1
inventory packets don't make us barf
2009-10-30Make the default and max RTO configurable int he linden client stackMelanie1-1/+7
2009-10-30* Disables automatic packet splitting on AvatarGroupsReply packets. This ↵John Hurliman1-2/+2
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* Moving parcel media and avatar update packets from the unthrottled ↵John Hurliman1-4/+8
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 Hurliman1-4/+4
* 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()
2009-10-28Modified visibilities of properties and methods. This is so that SL client ↵Mikko Pallari1-5/+5
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
2009-10-26Removing 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
2009-10-26Changed 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
2009-10-25Changing Scene.ForEachClient to use the synchronous for loop instead of ↵John Hurliman1-2/+2
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 Hurliman1-0/+24
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 Hurliman1-0/+3
* 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 Hurliman1-1/+1
setting throttles (normal)
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
2009-10-21* Change the OnQueueEmpty signature to send the flags of the queues that are ↵John Hurliman1-4/+0
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 Hurliman1-4/+0
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* Changed the timing calculations for sending resends/acks/pings from ↵John Hurliman1-26/+59
per-client back to per-scene * Testing a fix from Jim to make the cpu usage fix cleaner
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 Hurliman1-8/+39
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 Hurliman1-98/+45
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
2009-10-21Committing Jim's optimization to replace the 20ms sleep in outgoing packet ↵John Hurliman1-28/+70
handling with an interruptible wait handle
2009-10-20* Added a sanity check to GetScriptAssemblies() and GetScriptStates() for ↵John Hurliman1-0/+2
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 throttle speed optimizations to see if it brings stability backJohn Hurliman1-63/+53
* 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
