Another thread could come and turn off physics for a part (null PhysicsActor) at any point.
Had to turn off localCopy on warp3D CoreModules section in prebuild.xml since on current nant this copies all DLLs in bin/ which can be a very large number with compiled DLLs
No obvious reason for doing that copy - nothing else does it.
This adds ScenePresence to IClientAPI.SceneAgent earlier on in the add client process so that its information is available to EventManager.OnNewClient() and OnClientLogin()
Also add a code comment as to why we're caching friend information for child agents.
We need to cache child agents so that friends object edit/delete permissions will work across boarders on regions hosted by different simulators.
This reverts commit d9f7b8549b.
This allows us to avoid unnecessary multiple calls to the friends service.
All friends functions originate from the root agent and only go to other root agents in existing code.
This also allows us to eliminate complex ref counting.
On osgrid and other places, I have observed that manually sending appearance updates from the console often relieves grey avatar syndrome.
Despite hunting high and low, I haven't been able to find where this packet is sometimes being lost - it might be a persistent viewer bug for all I know.
Therefore, this experimental setting resends appearance data for everybody in the scene every 60 seconds. These packets are small and the viewer only fetches texture
data if it doesn't already have it.
Default is false.
The idea is to make the critical main scene loop as skinny as possible - it doesn't need to run things that aren't time critical and don't depend on update ordering.
This will be done gradually over time to try and uncover any issues. Many non-criticial scene loop activities are being launched on separate threadpool threads anyway.
This may also allow modules to register their own maintenance jobs without having to maintain their own timers and threads.
Currently the maintenance loop runs once a second, as opposed to the 89ms scene loop.
This lets us remove the dependency of OpenSim.Framework.dll on data/avataranimations.xml, which is not necessary for ROBUST.
This commit also takes care of the odd situation where animations are stored and used internally with uppercase names (e.g. "STAND")
but scripts refer to them with lowercase names (e.g. "sit").
Update() now accepts a frames parameter which can control the number of frames updated.
-1 will update until shutdown.
The watchdog updating moves above the maintc recalculation for any required sleep since it should be accounted for within the frame.
The previous lines-per-second measurement used for top scripts report was inaccurate, since lines executed does not reflect time taken to execute.
Also, every fetch of the report would reset all the numbers limiting its usefulness and we weren't even guaranteed to see the top 100.
The actual measurement value should be script execution time per frame but XEngine does not work this way.
Therefore, we use actual script execution time scaled by the measurement period and an idealised frame time.
This is still not ideal but gives reasonable results and allows scripts to be compared.
This commit moves script execution time calculations from SceneGraph into IScriptModule implementations.
The first llDie() could lock Scene.m_deleting_scene_object.
The second llDie() would then wait at this lock.
The first llDie() would go on to remove the second script but always abort it since the second script's WorkItem would not go away.
Easiest solution here is to remove the m_deleting_scene_object since it's no longer justified - we no longer lock m_parts but take a copy instead.
This also requires an adjustment in XEngine.OnRemoveScript not to use instance.ObjectID instead when firing the OnObjectRemoved event.
However, it looks like we should retain SP.ParentID since it's much easier to use that in places where another thread could change ParentPart to null.
Otherwise one has to clumsily put ParentPart in a reference, etc. to avoid a race.
This is to deal with the hundred lines of command splurge when one previously typed "help"
Modelled somewhat on the mysql console
One can still type help <command> to get per command help at any point.
Categories capitalized to avoid conflict with the all-lowercase commands (except for commander system, as of yet).
Does not affect command parsing or any other aspects of the console apart from the help system.
Backwards compatible with existing modules.
We can now do this since the entire scene and all objects within it are now successfully gc'd at the end of these tests.
This greatly improves the time taken to run each test (by reducing teardown time, not the time to actually do the test work that we're interested in).
Slightly simplifies config read in Scene constructor to help facilitate this.
OnNewScript fires when a script is added to a scene
OnRezScript fires when the script actually runs (i.e. after permission checks, state retrieval, etc.)
This allows scripts to run in child prims that are outside region boundaries.
This is an interim patch applied from http://opensimulator.org/mantis/view.php?id=5899 though it does not resolve that bug
Thanks tglion!
On the first frame, all startup scene objects are added to the physics scene.
This can cause a considerable delay, so we don't start raising the alarm on scene loop timeouts until the second frame.
This commit also slightly changes the behaviour of timeout reporting.
Previously, a report was made for the very first timed out thread, ignoring all others until the next watchdog check.
Instead, we now report every timed out thread, though we still only do this once no matter how long the timeout.
This involves
1) On forcible teleport, call m_scene.RequestTeleportLocation() rather than ScenePresence.Teleport() - only EntityTransferModule now should call SP.Teleport()
2) When avatar is being forcibly moved due to banlines, use a 'stop movement' tolerance of 0.2 to requested position rather than 1
This prevents the avatar sometimes being stuck to banlines until they teleport somewhere else.
This aims to fix some problems in http://opensimulator.org/mantis/view.php?id=5822
potential bad update that places an object at the opposite side of the
origin sim for a moment before actually crossing it. Especially important in
grids like OSG where lag between sims is high.
This fixes the problem by fixing the permissions module to look at root part permissions rather than having to do this for every caller.
Resolves http://opensimulator.org/mantis/view.php?id=5569
At least on mono 2.6.4, running GC.Collect() is not guaranteed to force gc of all objects when run in the same method where those objects had references.
Therefore, GC.Collect() is now being done in the per-script teardown of ObjectTortureTests.
In addition, scene loop update is being run after garbage collection in order to clean out the viewer update list of scene objects in the SceneGraph.
These measures mean that scene objects/parts are now garbage collected after a test run if deleted from the scene, resulting in a much better memory usage report (though probably still not very accurate).
However, deletion takes a very long time - what's really needed is to find out now why the entire scene isn't being GC'd by this measure.
This change hasn't yet been applied to the other stress tests.
Logging level was DEBUG before 312e145 (Fri Feb 3 2012).
312e145 also accidentally removed the 'general error' log message if any shape deserialization failed.
This commit restores it, though this has no functional impact.
Setting PermissionMask.All will cause next permissions to replace current permissions when the object is rezzed, since bit 4 will be set.
This is not correct behaviour for a freshly uploaded mesh. Freshly rezzed in-world prims also do not have bit 4 set (don't yet know exactly what this is).
Should resolve http://opensimulator.org/mantis/view.php?id=5651
This illustrates that references to Scene, SOG, etc. are not currently being released when a stress test ends (or at regression test end in general).
This means even the current stress tests take much more memory than they need, a problem that will have to be addressed.
The Path.GetDirectoryName call in Compiler.CompileFromDotNetText is unnecessary since AppDomain.CurrentDomain.BaseDirectory is always a directory.
Later path concatenation is already done by Path.Combine() which handles any trailing slash.
Removing Path.GetDirectoryName() will not affect the runtime but allows NUnit to work since it doesn't add a trailing slash to AppDomain.CurrentDomain.BaseDirectory.
This resolves the recent regression from deeb728 where notecards could not be saved in prim inventories.
This looks like a better solution than deeb728 since only non-caps updates pass in a transaction ID.
Hopefully resolves http://opensimulator.org/mantis/view.php?id=5873
These can be run using the "nant torture" target. They are not part of "nant test" due to their long-run future nature.
Such tests are designed to do some testing of extreme situations and give some feedback on memory usage, etc.
However, data can be inconsistent due to different machine circumstances and virtual machine actions.
This area is under development.
