This is somewhat more in keeping with something like osForceAttachToOtherAvatarFromInventory()
and potentially allows a separate osForceSit() command with High threat rather than VeryHigh that only sits the owner and can be enabled without enabling sit of other avatars.
Allows a script IN the target prim to force an avatar to sit on it using normal methods as if called by the client.
Overload method of osForceSit() to allow a script NOT in the target prim to force an avatar to sit on the target prim using normal methods as if called by the client.
This patch is based on previous work from
http://opensimulator.org/mantis/view.php?id=4492
and also includes the suggestions from justincc including change of threat level
Thank you Christos Lightling.
This code originates from when IEntityTransferModule was shared rather than one per region.
Now it's one per region we know that callers are always in the same scene as the module.
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)
Unlike "debug lludp packet" which logs at the point where OpenSim first asks the clientstack to send a certain outgoing packet, this logs immediately before the actual send.
For low-level debugging purposes.
This allows one to log the packets received by a particular bot that are not duplicates of already received packets.
Similar to the OpenSimulator command at the same name but currently any positive level logs all received packets.
No facility yet for logging outgoing packets.
For debug purposes.
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()

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.
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.
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.
However, many locks remain since they may effectively be providing transactionality in some operations (e.g. prim updates across multiple tables).
These are candidates for being replaced with proper database transactions, since this would not block unrelated operations (e.g. land save and object save)
or unrelated operations on the same tables (e.g. storage of one linkset whilst another is being removed).
In practice, any performance deg due to contention is probably rare and short lived as the major prim operations are performed in memory and only persisted some time afterwards.
These locks are not necessary since the connection is taken from the underlying mysql pool and not shared.
Such locking is already not done by some other parts of OpenSim.Data.MySQL.

Disabled by default. Currently can only be enabled with console "debug lludp oqre start" command, though this can be started and stopped whilst simulator is running.
When a connection requires packet queue refill processing (used to populate queues with entity updates, entity prop updates and image queue updates), this is done via Threadpool requests.
However, with a very high number of connections (e.g. 100 root + 300 child) a very large number of simultaneous requests may be causing performance issues.
This commit adds an experimental engine for processing these requests from a queue with a persistent thread instead.
Unlike inbound processing, there are no network requests in this processing that might hold the thread up for a long time.
Early implementation - currently only one thread which may (or may not) get overloaded with requests. Added for testing purposes.
Also closes behaviours on disconnect instead of interrupt, though this makes no practical difference.
If existing behaviour is None, other added behavious will not take affect until None is removed (as this is an infinite wait until interrupted).
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.
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.
