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.
Unfortunately, the OnLoginsEnabled event is currently only guaranteed to fire if the RegionReady module is active.
However, we can instantiate the AuthorizationService in the module RegionLoaded method since by this time all other modules will have been loaded
The asset data plugin now implements IXAssetData rather than IAssetData so the ordinary AssetService should no longer pick it up.
This replaces the changes in 92b1ade. There is no longer any need to adjust your StandaloneCommon.ini/Robust.ini/Robust.HG.ini files.
This may explain very recent issues in the last few weeks where textures have been disappearing or turning white (as they were going to different places).
Unfortunately, you will need to rollback to an earlier database backup or reupload the textures.
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.

from region modules. The LSL translator is extended to generate the
modInvoke format of commands for directly inlined function calls.
A region module can register a function Test() with the name "Test".
LSL code can call that function as "Test()". The compiler will translate
that invocation into modInvoke("Test", ...)
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.
This seems to be a particular problem with ReaderWriterLockSlim, though other locks can be affected as well.
It has been seen to happen when llDie() is called in a linkset running more than one script.
Alleviation here means supplying a ScriptInstance.Stop() timeout of 1000ms rather than 0ms, to give events a chance to complete.
Also, we check the IsRunning status at the top of the ScriptInstance.EventProcessor() so that another event doesn't start in the mean time.
Ultimately, a better solution may have to be found since a long-running event would still exceed the timeout and be aborted.
.NET 4.0 added the method Stream.CopyTo(stream, bufferSize). For .NET 3.5
and before, WebUtil defined an extension method for Stream with the signature
Stream.CopyTo(stream, maxBytesToCopy). The meaning of the second parameter
is different in the two forms and depending on which compiler and/or
runtime you use, you could get one form or the other. Crashes ensue.
This change renames the WebUtil stream copy method to something that
cannot be confused with the new CopyTo method defined in .NET 4.0.
This is configured in the new [Estates] section of OpenSim.ini.
If a default estate is configured then all new regions are automatically joined to it instead of asking the user.
If the default estate does not already exist then it is created.
Current default behaviour remains the same - the user is asked for estate details when necessary.
Thanks to Frenando Oliveira for the patch which I adapated further.
- Added an inventory cache for caching root and system folders
- Synchronized the remote inventory connector, so that all the remote inventory calls are serialized
This will not make much difference in the hold ups. We'd have to move the FireAndForget high up to AddInventoryItem, but that opens up a can of worms regarding the notification of the recipient... the recipient would be notified of the offer before the items are effectively in his inventory, which could lead to surprises.
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 should not currently be used in any circumstances except for experimentation.
Database tables used by this plugin can still change at any time with no migration path.
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.)
I believe this was originally required back when there could be two LocalGridServiceConnectors but this is no longer the case.
Having such statics makes performance testing much more difficult since they prevent GC of objects unless static references are explicitly nulled.
They were all failing assertions but the exceptions these threw were caught as expected Exceptions.
I don't think we can easily distinguish these from the Exceptions that we're expecting.
So for now we'll do some messy manually checking with boolean setting instead.
This patch also corrects the assertions themselves.
The part reverted is from commit 2ebb421.
Unfortunately, IAvatarFactoryModule.SetAppearance() does not transfer attachments.
I'm not sure how to do this separately, unfortunately I'll need to leave it to Dan :)
Regression test added for this case.
Mantis ref: http://opensimulator.org/mantis/view.php?id=5914
Some successful collision attacks have been carried out on sha1 with speculation that more are possible.
http://en.wikipedia.org/wiki/Cryptographic_hash_function#Cryptographic_hash_algorithms
No successful attacks have been shown on sha256, which makes it less likely that anybody will be able to engineer an asset hash collision in the future.
Tradeoff is more storage required for hashes, and more cpu to hash, though this is neglible compared to db operations and network access.
Whether this is worthwhile is debatable since here we are not transmitting data over a network
In addition, jpeg2000 (the biggest data hog) is already a compressed image format.
May not remain.
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!
This is an extremely crude implemenation which almost works by accident. Nevertheless it does work.
It can be tested with the instructions at http://opensimulator.org/wiki/Feature_Proposals/Deduplicating_Asset_Service#Testing
It does not interact at all with the existing asset service or any data stored there.
This code is subject to change without notice and should not be used for anything other than gawking.
This is the start of exploring the creation of a bundled OpenSimulator asset service that does de-duplication and possibly file storage of assets.
Along the lines of coyled's SRAS, but not intended to replace, merely to act as a more performant bundled default.
Might end up nicking stuff from kcozen's patch at http://opensimulator.org/mantis/view.php?id=5429

Feedback and discussion welcome as commits are made.
This is already being done in the other place where a sensor is added.
Adding a sensor whilst another thread is iterating over the sensor list can cause a concurrency exception.
are osReplaceString(string source, string patter, string replace, integer count, integer start)
The count parameter specifies the total number of replacements to make, -1 makes
all replacements.
This is so that the static MainConsole.Instance doesn't retain references to methods registered by scene and other modules to service commands.
This prevents the scene from being garbage collected at the end of a test.
This is not the final thing preventing GC - next up is the timer started by SimStatsReporter that holds a reference to Scene that prevents end of test gc.
MySQL and MSSQL have it as Sandbox, sqlite as sandbox.
In various different places in every plugin the wrong casing is used...
Consistency, who needs it? Or one day sqlite can change to Sandbox.
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.

In over 4 years this never progressed beyond an unimplemented stub.
This doesn't mean that it can't come back if someone is interested in implementing PhysX support.
In theory, this means that a 64-bit Windows OS user can now run OpenSim.exe with ODE and use more than 2 (or 3) GB of memory.
However, this is completely untested since I don't currently own a 64-bit Windows box. Feedback appreciated.
Using OpenSim.32BitLaunch.exe should continue to work. Other platforms are unaffected.
This will currently not work with sqlite - I will add that too if this works.
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.
too slow they would circumvent the cache (piling up on the network service
and making the problem even worse). This condition happens frequently
during permission checks.
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.
If velocity reaches 256 in any vector then bad things happen with ODE, so we now clamp this value.
In addition, a falling avatar is clamped by default at 54 m/s, which is the same as a falling skydiver.
This also appears to be the value used on the linden lab grid.
This should resolve http://opensimulator.org/mantis/view.php?id=5882
