prim update to only triple queuing. Existing method was:
1. Schedule prim for update, adding to scene update list
2. Update on SOGs during heartbeat queues update onto each SceneViewer
3. Update on SPs during heartbeat queues update onto each IClientAPI
4. ProcessEntityUpdates queues updates into UDP send stack
Now the SceneViewer has been eliminated so updates are scheduled at any
time and then put onto the IClientAPI priority queues immediately during
SceneGraph.UpdateObjectGroups.
This is to avoid http://opensimulator.org/mantis/view.php?id=5783 when a collision with a ground sitting avatar causes that avatar to automatically stand and sometimes not be able to move
A better solution may be to keep gound sitting avatars solid but remove their collision status. However, this requires some physics code work.
This means that if the avatar is within 10 meters of the selected target, it sits on it immediately without walking.
Existing autopilot outside this range will be disabled in a later commit
This is to partially address http://opensimulator.org/mantis/view.php?id=5769
We don't need to call SP.HandleAgentSit() again if we are within 10m since the autopilot won't trigger.
By calling it twice, the position of the sitting NPC was wrongly adjusted, ending up near <0,0,0>.
However, this change does mean that NPCs further than 10m away will not attempt to autopilot to the prim, though this code was broken anyway (is actually a different mechanism to normal NPC movmeent).
Hopefully this can be addressed soon.
This was meant to help with the script in http://opensimulator.org/mantis/view.php?id=5772 but it doesn't work.
Probably the event is fired before the physics actor has been set up again for the stood avatar.
Fixing that would be much more complicated, but processing the event last of all seems like a good idea in any case.
from previous commit which sort out which iterator is used are left
intact. A discussion is needed as to what constitutes an avatar vs a
ScenePresence.
the 3 iteration functions so more of them are using the correct
iteration for the action they are performing. The 3 iterators that seem
to fit all actions within OpenSim at this time are:
ForEachAvatar: Perform an action on all avatars (root presences)
ForEachClient: Perform an action on all clients (root or child clients)
ForEachRootClient: Perform an action on all clients that have an avatar
There are still a dozen places or so calling the old
ForEachScenePresence that will take a little more refactoring to
eliminate.
UpdateFlag is now referenced/used only within SOP and SOG. Outsiders are
using ScheduleFullUpdate, ScheduleTerseUpdate or ClearUpdateSchedule on
SOP consistently now. Also started working toward eliminating those
calls to ScheduleFullUpdate, ScheduleTerseUpdate or ClearUpdateSchedule
from outside SOP in favor of just setting properties on SOP and let SOP
decide if an update should be scheduled. This consolidates the update
policy within SOP and the client rather than everywhere that makes
changes to SOP. Some places forget to call update while others call it
multiple times, "just to be sure".
UpdateFlag and Schedule*Update will both be made private shortly.
UpdateFlag is intended to be transient and internal to SOP so it has
been removed from XML serializer for SOPs.
In AvatarFactoryModule.HandleAppearanceUpdateTimer(), we loop through appearance save and send requests and dispatch via a FireAndForget thread.
If there was more than one request in the save or send queue, then this led to a subtle race condition where the foreach loop would load in the next KeyValuePair before the thread was dispatched.
This gave the thread the wrong avatar ID, leaving some avatar appearance cloudy since appearance data was never sent.
This change loads the fields into local references so that this doesn't happen.
Format is osNpcSit(<npc-uuid>, <target-uuid>, OS_NPC_SIT_IMMEDIATE)
e.g. osNpcSit(npc, llGetKey(), OS_NPC_SIT_IMMEDIATE);
At the moment, sit only succeeds if the part has a sit target set.
NPC immediately sits on the target even if miles away - they do not walk up to it.
This method is in development - it may change so please don't trust it yet.
Standing will follow shortly since that's kind of important once you're sitting :)
ways to access the list/dictionary of child regions and locking was
inconsistent. There are now public properties which enforce locks.
Callers are no longer required to create new copies of lists.
Some of the places where agentMS was added were in separate threads launched by the update loop. I don't believe this is correct, since such threads are no longer contributing to frame time.
Some of the places were also driven by client input rather than the scene loop. I don't believe it's appropriate to add this kind of stuff to scene loop stats.
These changes hopefully have the nice affect of making the broken out frame stats actually add up to the total frame time
SP still has an implementation but this is now just a public method on SP rather than an abstract one in EntityBase.
No point making the code more complex until it actually needs to be,
