Now, such excpetions are caught by an exception handler and just an error message is shown.
This was the kind of exception causing these fatal server crashes:
APPLICATION EXCEPTION DETECTED: System.UnhandledExceptionEventArgs^M
^M
Exception: System.ArgumentOutOfRangeException: Argument is out of range.
Parameter name: offset exceeds the size of buffer
at System.Net.Sockets.NetworkStream.BeginRead (System.Byte[] buffer, Int32 offset, Int32 size, System.AsyncCallback callback, System.Object state) [0x00000] in <filename unknown>:0
at HttpServer.HttpClientContext.OnReceive (IAsyncResult ar) [0x00000] in <filename unknown>:0 ^M
^M
Application is terminating: True^M
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.
This isn't a perfect solution since there can be a race between the taint processing and taint setting, as force needs to be reset after processing.
Needs careful locking in the future.
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.
This can be specified on pCampbot.exe by using g in the list of behaviours for the new -behaviours,-b switch
e.g. -b p,g to get both existing physics and grabbing behaviours.
grabbing is primitive, it attempts grabs on random prims whether they're actually signalled as clickable or not.
behaviour is currently primitive overall, behaviours are just executed in a list
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.
