or final asset import takes too long remove remaining requests from same user to prevent hold up of other user's incoming attachments.
This improves upon the earlier naive simply queueing immplementation.
Threshold is 30 seconds. If this happens to a user they can relog and fetch will be reattempted.

(iteration) can be controlled by the caller.
This is to enable an imminent change where incoming HG scene object fetching can assess the time taken by each request rather than being forced to perform all requests in one call.
Soon, this will replace the existing UuidGatherer since it is both simpler and more flexible.

Instead of processing all incoming attachment scene object concurrently, process them consecutively to eliminate potential overload from this source.
This is a naive implementation because it does not currently account for slow foreign asset services.
Although it may take longer, this approach may also improve attachment visibility for HG avatars
since the scene object is now always added to the scene after receiving assets from the foreign service and not before.

"show threadpool calls" now also returns named (labelled), anonymous (unlabelled) and total call stats.

client being added to the manager without IClientAPI.SceneAgent being set.
This is done by adjusting the order of code so that SceneAgent will always be set before adding the client.
Various parts of the code (rightly) assume that a a client registered to the manager will always have a SceneAgent set no matter what.

entering the scene that isn't initially logging on. This will execute tasks consecutively rather than concurrently.
This has two aims
1) Reduce initial teleport failures when a foreign Hypergrid user enters a region by not holding up the teleport for attachment rez (this can be particularly costly when HG gets all assets in the object graph.
2) Reduce server load that may impact other simulator activities.
This complements existing JobEngine options that perform initial login attachment rez and appearance send in consecutive tasks.

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.

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.

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!

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.

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.

[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)

At this point sp != null so no check required.

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.

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).

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()

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.

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.

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.

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.

[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.

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.
