* Eliminate a few unnecessary calculations in the maintenance loop.Justin Clark-Casey (justincc)2014-11-251-7/+17
| | | | Also uses wait event instead of sleep for periodicity control.
* Fix recent minor regression where the default frame time wasn't being set if ↵Justin Clark-Casey (justincc)2014-11-251-2/+1
| | | | | | there was no startup config section. Caused some regression tests to fail.
* Improve frame time stability by taking a few unnecessary repeated ↵Justin Clark-Casey (justincc)2014-11-252-21/+42
| | | | | | calculations out of the main scene loop. Also uses a wait event to sleep rather than a Thread.Sleep to allow the loop to be interrupted in a more controlled manner when necessary.
* Set ThreadPriority on main scene thread to highest.Justin Clark-Casey (justincc)2014-11-251-0/+1
| | | | This will only have an effect on Windows systems or mono with the (not recommended) mono-3.2.8 debug patch https://gist.github.com/justincc/31e52218d098529b4696 applied
* Temporarily add root agent rez attachments work to job engine if it is ↵Justin Clark-Casey (justincc)2014-11-251-4/+8
| | | | | | running rather than as a fire and forget. Experiment to see if serializing attachment rez and send initial data jobs improves other parts of sim performance.
* Add experimental job engine to see if queueing some existing async work ↵Justin Clark-Casey (justincc)2014-11-251-1/+1
| | | | | | | | during root agent entry to a region improves perf rather than always attempting to execute everything concurrently Job engine is controlled via "debug jobengine start|stop|status". Can only currently be enabled and disabled dynamically at runtime. Currently only applies to code sending initial region data (objects, other avatar data) to a client.
* refactor: capitalize SOP.moveToTarget() and stopMoveToTarget() in accordance ↵Justin Clark-Casey2014-11-192-4/+4
| | | | with code guidelines and the rest of the methods.
* If calling llStopMoveToTarget() on an in-world prim, don't send an ↵Justin Clark-Casey2014-11-191-2/+1
| | | | | | | unnecessary object update if the prim was not moving to target. This involves making PhysicsActor.PIDActive get as well as set. On physics components that don't implement this (all characters and some phys engines) we return false.
* Remove SOP.StopMoveToTarget scheduled update which is now being done in ↵Justin Clark-Casey2014-11-191-3/+0
| | | | SOG.stopMoveToTarget() as of last commit 67e568
* If llStopMoveToTarget() is called on an attachment, then stop the avatar if ↵Justin Clark-Casey2014-11-191-5/+19
| | | | | | | it was moving to target. Same behaviour as on Linden Lab grid. Will probably also address http://opensimulator.org/mantis/view.php?id=7369 by not generating spurious object updates when llStopMoveToTarget() is called in attachments where the avatar is not moving.
* Fix issue where llRemoteLoadScriptPin() would treat 0 (the default) as a ↵Justin Clark-Casey2014-11-111-8/+12
| | | | | | valid set pin in a destination prim rather than the unset no pin state Adds regression test for this case.
* Fix transferring inventory from prims to agent inventoryMelanie Thielker2014-10-161-6/+11
|
* Add LSL transaction_result event.Justin Clark-Casey (justincc)2014-10-041-0/+1
| | | | | | | This is cinderblocks' transaction_result.diff from http://opensimulator.org/mantis/view.php?id=7329 but I have used lsl.parser.cs and lsl.lexer.cs files generated directly from opensim-libs rather than those supplied in the patch. I also added scriptEvents.transaction_reuslt. The required parser/lexer generation file changes were made in commit d564f28 in the opensim-libs repo. Thanks!
* Do not add attachments to the region scene object backup list.Justin Clark-Casey (justincc)2014-10-021-2/+2
| | | | Attachment persistence is not handled in this way and this just results in a load of busy work until a check in each SOG terminates a backup check for attachments anyway.
* Set appearance refresh to false by default.Justin Clark-Casey (justincc)2014-10-021-1/+1
| | | | | | This setting was originally added some time ago to deal with issues where appearance was not received properly by all users. However, it does not scale well with large numbers of agents. Disabling to see if the original problem has abated or whether this will have to be tackled in another way.
* Move expired objects cleaning trigger to the maintenance thread of a region ↵Justin Clark-Casey (justincc)2014-09-271-20/+23
| | | | | | | rather than it's main scene loop. [Startup] default setting UpdateTempCleaningEveryNFrames becomes UpdateTempCleaningEveryNSeconds. Default becomes 180s instead of effective 182s (which would also vary with any changes in frame time or extra long frames)
* Remove an unnecessary check at the bottom of Scene.CloseAgent()Justin Clark-Casey (justincc)2014-09-241-7/+2
| | | | At this point sp != null so no check required.
* This fixes the Scene thread renaming issueBlueWall2014-09-171-1/+0
|
* Undo "Revert "Small changes to threading to send thread names to unmanaged ↵BlueWall2014-09-171-1/+3
| | | | | | | | threads. Needs Mono 3.6+ to see thread names in utilities like top -H . Some formatting of the thread name to fin in the 16 byte limit on Linux. Please test on Windows to see if the work has any adverse effects."" Fix for break in next commit This reverts commit 376fab140227e92dbd841436509a97b87c9e7792.
* Changes to be committed: modified: ↵Edward2014-09-171-0/+15
| | | | OpenSim/Region/Framework/Scenes/Scene.PacketHandlers.cs modified: OpenSim/Region/ScriptEngine/Shared/Api/Implementation/LSL_Api.cs This solves mantis bug# 5005: llRegionSay script does not trigger ChatFromWorld event. This was solved by adding World.SimChat() command to the llRegionSay() function (per suggestion of DrCuriosity). Additionally this fixes llRegionSayTo() which was also not functioning by adding a World.SimChat() command and adding a new SimChatToAgent() overrided function to Scene.PacketHandlers.cs This is the second patch revision. Corrections made to the position of World.SimChat() and removal of tabs per suggestion by justincc.
* Revert "Small changes to threading to send thread names to unmanaged ↵BlueWall2014-09-171-3/+1
| | | | | | | threads. Needs Mono 3.6+ to see thread names in utilities like top -H . Some formatting of the thread name to fin in the 16 byte limit on Linux. Please test on Windows to see if the work has any adverse effects." This reverts commit af286d5fcb688e8b64202b6deca4f249e9a2b6b8. Issue with Jenkins builds
* Small changes to threading to send thread names to unmanaged threads. Needs ↵BlueWall2014-09-171-1/+3
| | | | Mono 3.6+ to see thread names in utilities like top -H . Some formatting of the thread name to fin in the 16 byte limit on Linux. Please test on Windows to see if the work has any adverse effects.
* Fix issues where setting llSetTextureAnim(FALSE... did not work properly).Justin Clark-Casey (justincc)2014-09-121-11/+20
| | | | | I ended up amalgamating patches from http://opensimulator.org/mantis/view.php?id=7313 and http://opensimulator.org/mantis/view.php?id=7318 Thanks a lot to both bobshaffer2 and cinderblocks.
* Fix regression from recent a02dae5 where stand positions are no longer ↵Justin Clark-Casey (justincc)2014-09-111-3/+2
| | | | | | | correct when a sit target is specified. Adjusts stand position using just avatar position relative to the root prim instead. Fixes http://opensimulator.org/mantis/view.php?id=7315 and preserves previous fix for http://opensimulator.org/mantis/view.php?id=7299
* For monitoring purposes, start non-timeout tasks (which do not currently use ↵Justin Clark-Casey (justincc)2014-09-052-13/+10
| | | | | | | a threadpool) via Watchdog.RunInThread() rather than Util.RunThreadNoTimeout() The functionality is the same but this allow us to monitor such tasks via "show threads" and abort them for test purposes, etc. Also extends thread names to provide more info (e.g. SendInitialDataToClient says what client the task is for).
* Add [EntityTransfer] AllowAvatarCrossing setting to determine whether ↵Justin Clark-Casey (justincc)2014-09-032-1/+19
| | | | | | avatars are allowed to cross regions at all. Defaults to true. For test purposes.
* Fix recent regression from 473c5594 where camera started to judder on moving ↵Justin Clark-Casey (justincc)2014-09-021-15/+25
| | | | | | | vehicles. Other parts of OpenSimulator are relying on SP.Velocity == 0 for vehicles. So add and use SP.GetWorldVelocity() instead when we need vehicle velocity, along the same lines as existing SP.GetWorldRotation()
* As per the LL grid, if an avatar is sitting then return it's velocity ↵Justin Clark-Casey (justincc)2014-08-301-0/+5
| | | | | | relative to the region rather than relative to its seat. Resolves http://opensimulator.org/mantis/view.php?id=7175
* Fix issue where moving a seated avatar would not adjust their subsequent ↵Justin Clark-Casey (justincc)2014-08-301-1/+1
| | | | | | stand position. Addresses http://opensimulator.org/mantis/view.php?id=7299
* Implement STATUS_BLOCK_GRAB_OBJECT in llSetStatus()/llGetStatus() and ↵Justin Clark-Casey (justincc)2014-08-293-20/+17
| | | | | | | | | correct effect of STATUS_BLOCK_GRAB As per http://wiki.secondlife.com/wiki/LlSetStatus Setting STATUS_BLOCK_GRAB_OBJECT prevents or allows move of a physical linkset by grab on any prim. Setting STATUS_BLOCK_GRAB prevents or allows move of a physical linkset by grab on a particular prim. Previously, setting STATUS_BLOCK_GRAB would prevent drag via all prims of the linkset.
* Ignore whitespace when reading serialized XML objects.Justin Clark-Casey (justincc)2014-08-294-188/+192
| | | | | | This was previously effectively being done by XmlDocument in the multiple passes through the XML. This change tells XmlReader to ignore whitespace. This also means changing arguments to use XmlReader instead of XmlTextReader (a descendent of XmlReader) directly. XmlReader.Create() has been the recommend way to create XML readers since .NET 2.0 as per MS SDK and is the only way to specific ignore whitespace settings.
* minor: Eliminate more unnecessary code copying individual parameters for ↵Justin Clark-Casey (justincc)2014-08-281-17/+19
| | | | Vector3 copying in Scene - this is not necessary as Vector3 is a value type
* On code section that rezzes single objects and attachments, reduce CPU use ↵Justin Clark-Casey (justincc)2014-08-283-69/+123
| | | | | | | | by reading asset XML a single time with a stream reader rather than multiple times. Reading large XML documents (e.g. complex attachments) is CPU expensive - this must be done as few times as possible (preferably just once). Reading these documents into XmlDocument is also more resource intensive than using XmlTextReader, as per Microsoft's own publication "Improve .NET Application Performance and Scalability" Optimization of other cases will follow if this change is successful.
* Don't allow update timer to invoke another scene update if the previous is ↵Justin Clark-Casey (justincc)2014-08-261-1/+10
| | | | still active.
* Fix frame times when updating scene on timer.Justin Clark-Casey (justincc)2014-08-261-15/+17
|
* Implement experimental non-default mechanism to update scene via a timer ↵Justin Clark-Casey (justincc)2014-08-262-35/+62
| | | | | | | | rather than a persistent thread with sleep. This is to see if an inaccuracy in sleep times under load is responsible for increase in frame times even when there is spare time still available. Can currently only be activated by setting "debug scene set update-on-timer true". Can be switched between timer and thread with sleep updates whilst the scene is running.
* If a user moves back in sight of a child region before the agent has been ↵Justin Clark-Casey (justincc)2014-08-151-6/+3
| | | | closed on teleport, don't unnecessarily resend all avatar and object data about that region.
* On teleport to a region that already has a child agent established (e.g. a ↵Justin Clark-Casey (justincc)2014-08-151-32/+43
| | | | | | neighbour) don't resend all the initial avatar and object data again. This is unnecessary since it has been received (and data continues to be received) in the existing child connection.
* Make RootTerseUpdatePeriod and ChildTerseUpdatePeriod configurable in ↵Justin Clark-Casey (justincc)2014-08-141-0/+3
| | | | | | | | | | [InterestManagement] in OpenSim.ini for experimental purposes. If n > 1 for RootTerseUpdatePeriod only every n terse update is actually sent to observers on same region, unless velocity is effectively zero (to stop av drift). If n > 1 for ChildTerseUpdatePeriod only every n terse update is sent to observers in other regions, unless velocity is effectively zero. Defaults are same as before (all packets are sent). Tradeoff is reduction of UDP traffic vs fidelity of observed av mvmt. Increasing n > 1 leads to jerky observed mvmt immediateley for root, though not on child, where experimentally have gone to n = 4 before jerkiness is noticeable.
* Make some existing reprioritization values changeable outside the scene for ↵Justin Clark-Casey (justincc)2014-08-141-15/+18
| | | | | | test purposes, and use more consise property syntax. No functional change.
* On entity transfer of scene presence, replace polling sleep in ↵Justin Clark-Casey (justincc)2014-08-131-14/+13
| | | | | | | SP.WaitForUpdateAgent() with a triggered event instead. Rapid polls are more expensive than triggered events (several polls vs one trigger) and may be problematic on heavily loaded simulators where many threads are vying for processor time. A triggered event is also slightly quicker as there is no maximum 200ms wait between polls.
* Remove redundant origin region lock in SP.CompleteMovement()Justin Clark-Casey (justincc)2014-08-131-6/+1
| | | | This is already going to be correctly set by WaitForUpdateAgent() earlier on in that method, which is always called where a callback to the originating region is required.
* Change RootRotationUpdateTolerance from 0.01 to 0.1 in code as well.Justin Clark-Casey (justincc)2014-08-081-1/+1
|
* Fixed crash when using Allowed/Denied Viewers, and the viewer's name is ↵Oren Hurvitz2014-08-061-2/+2
| | | | | | shorter than one of the test strings This fixes http://opensimulator.org/mantis/view.php?id=7294
* Add RootPositionUpdateTolerance, RootRotationUpdateTolerance, and ↵Justin Clark-Casey (justincc)2014-08-061-0/+7
| | | | | | | RootVelocityUpdateTolerance parameters to [InterestManagement] in OpenSimDefaults.ini These govern when AgentUpdates are sent to observers on position, rotation and velocity changes to an avatar (including the avatar themselves). Higher values reduce AgentUpdate traffic but at a certain level will degrade smoothness of avatar and perceived avatar movement.
* refactor: Rename recent new Client*UpdateTolerance to Root*UpdateTolerance ↵Justin Clark-Casey (justincc)2014-08-062-13/+13
| | | | for better accuracy and consistency with other similar parameters
* Implement "scene debug set root-upd-per" for dropping 1 in N root agent ↵Justin Clark-Casey (justincc)2014-07-292-2/+24
| | | | | | | updates except to originator For experimental purposes. Also corrects a previous bug where each terse update sent was counted rather than each set of terse updates to agents.
* Add debug mechanism for only sending 1 in N AgentUpdate packets to child agents.Justin Clark-Casey (justincc)2014-07-292-1/+18
| | | | | | Allows experiments in manually reducing updates under heavy load. Activated by "debug scene set client-upd-per" console command. In a simple test, can send as few as every 4th update before observed movement starts becoming disturbingly rubber-banded.
* Make it possible to change avatar position update, rotation and velocity ↵Justin Clark-Casey (justincc)2014-07-292-8/+22
| | | | | | | tolerances on the fly. This is done via "debug scene set client-pos-upd, client-rot-upd, client-vel-upd". For testing purposes.
* Allow the "debug scene set physics false|true" command to work when ↵Justin Clark-Casey (justincc)2014-07-291-20/+43
| | | | | | bulletsim physics is running in a separate thread. This will also allow the "disable physics" setting in the region debug viewer dialog to work in this circumstance.
