During the heartbeat loop, Update() is called on every SceneObjectGroup which in turn checks if any SceneObjectPart has changed. For large regions (> 100k prims) this work consumes 20-30% of a CPU even though there are only a few objects updating each frame.
There is only one other reason to check every object on every frame, and that is the case where a script has registered the object with an "at target" listener. We can easily track when an object is registered or unregistered with an AtTarget, so this is not a reason to check every object every heartbeat.
In the attached patch, I have added a dictionary to the scene which tracks the objects which have At Targets. Each heartbeat, the AtTarget() function will be called on every object registered with a listener for that event. Also, I added a dictionary to SceneGraph which stores references to objects which have been queued for updates during the heartbeat. At each heartbeat, Update() is called only on the objects which have generated updates during that beat.
* Fixes 'Inconsistent Attachment State' when teleporting into another region besides the SW most region slot on a MegaRegion.
* Fixes a host of other unintended attachment border cross edge cases that lead to Inconsistent attachment state.
* This also contains some inactive preliminary code for disconnecting combined regions that will be used to make one root region a virtual region of a new root region.
This involved adding a new OnUpdatePrimSingleRotationPosition event to IClientAPI so that we can get the changed position from the client.
Btw adding new events to IClientAPI is really tedious where you have to copy the change across to at least 5 or 6 other files.
[Note this doesn't fix the bug where any rotation changes to the root prim (but not the whole linkset) cause rotation errors on the child prims.]
The patch included updates the root and child prims' AttchedAvatar
with the right UUID. It also cleans the AttachedAvatar properties
for the root and child prims on Drop and Detach
This may break a lot of things, but it needs to go in. It was tested in standalone and the UCI grid, but it needs a lot more testing.
Known problems:
* HG asset transfers are borked for now
* missing texture is missing
* 3 unit tests commented out for now
arbitrary combinations of root and child prims from one or multiple
link sets. Please test throughly and consider things UNSTABLE until
this is proven out.
Changes to enable script state persistence across non-restart
serialization situations (inventory/OAR/attachments)
Also fixing test cases for OAR and IAR so they don't barf with the new code.
An attachment with the physical checkbox checked will not allow the
phantom checkbox to be cleared. This interfers with scripting
functions such as llMoveToTarget(), which won't work while an object
is phantom. If the prim containing the script is rezzed to the ground,
it will then allow the phantom checlbox to be cleared, and the script
works as expected.
Addresses Mantis #3381
The current implementation works as expected if the object has no rotation or
only rotation around the Z axis; you can spin the object left or right (around
the world Z axis).
It works a little unexpectedly if the object has a non-Z-axis rotation; in this
case the body is spun about its local Z axis, not the world Z-axis. (But SL
also behaves oddly with a spin on an arbitrarily rotated object.)
llSetHoverHeight() should not clamp the x/y position of an object the way MoveTo does,
and it should recalculate the absolute height to hover at as an object moves to reflect
the current ground/water height under it.
Correctly implementing required adjusting the Physics interfaces and implementing at
the physics plug-in level. The attached is a patch that correctly implements
llSetHoverHeight() including updates to the ODE physics plug-in.
* Moves Entity Updates into a seperate thread, allowing for OpenSim to utilize a computers CPU more effectively in return for potentially greater user and prim capacity.
* Removes an expensive Sqrt call performed during Update on each object. This should lower CPU requirements for high-prim regions with physics enabled.
* MXP Changes: Centers the region around 0,0 for primitives instead of 128,128. Prim display should now look more correct for MXP viewers.
* Added log4net dependency to physxplugin in prebuild.xml.
* Added missing m_log fields to classes.
* Replaced Console.WriteLine with appropriate m_log.Xxxx
* Tested that nant test target runs succesfully.
* Tested that local opensim sandbox starts up without errors.
The two most notable changes in the crossing process were:
* Object gets passed in only one message, not two as done before.
* Local object crossings do not get serialized, as done before.
OpenSim.Region.Environment into a "framework" part and a modules only
part. This first changeset refactors OpenSim.Region.Environment.Scenes,
OpenSim.Region.Environment.Interfaces, and OpenSim.Region.Interfaces
into OpenSim.Region.Framework.{Interfaces,Scenes} leaving only region
modules in OpenSim.Region.Environment.
The next step will be to move region modules up from
OpenSim.Region.Environment.Modules to OpenSim.Region.CoreModules and
then sort out which modules are really core modules and which should
move out to forge.
I've been very careful to NOT BREAK anything. i hope i've
succeeded. as this is the work of a whole week i hope i managed to
keep track with the applied patches of the last week --- could any of
you that did check in stuff have a look at whether it survived? thx!
