This is to help track down http://opensimulator.org/mantis/view.php?id=6359 where creator IDs on items and rezzed objects have been reported to sometimes change.
This should never happen - a particular item should never change creators (if an item is given then a new item (with new id) is created).
Invariants are inventory type, asset type, folder (changed only on MoveItems()), CreatorIdentification and Owner.
If caller attempts to change an invariant, warning is logged but other properties are still changed.
If you see this warning, reporting on Mantis 6359 would be very welcome with the exact operation being done at the time.
This prevents a slow grid information network call from holding up the main packet handling thread.
There's no obvious race condition reason for not doing this asynchronously.
Halt already occurs if the relevant config sections are not present.
So it also makes sense to halt if the implementations themselves cannot be loaded.
This is because macosx mono is 32-bit and this can't p/invoke 64-bit binaries.
However, the reverse is also true.
If OpenSimulator stops working for you then please complain! Long term alternative is probably to build a fat binary with both architectures.
This is to avoid the entire scene loop being held up when the group service is slow to respond.
There's no obvious reason for these queries to be sync rather than async.
Uses new IEntityInventory.TryGetScriptInstanceRunning()
Makes it clearer that TaskInventoryItem.ScriptRunning cannot be used as it is temporary and not updated.
This was because we were removing by circuitcode where NPCs have no code.
Now removing by agent ID instead.
This commit also fixes the "show circuits" console command to work properly where the circuit has no associated IP address.
Unlike "save oar", this was happening on the same thread as the original request.
The timeout happens on another so the original thread is never aborted.
On "save oar" this leaves the thread hanging (still bad) but on "save iar" it left the console thread hanging.
Temporary fix is to make "save iar" do asset request on a separate thread, like "save oar".
Longer term fix will be to restructure asset save to use a ManualResetEvent rather than a separate timeout timer.
XEngine listeners to EventManager.OnShutdown which is triggered from base.Close().
Possibly it could listen for the earlier OnSceneShuttingDown instead, but the easier solution right now is to relocate disposal of the physics scene.
This bug has existed since c150320 (Thu Jul 26 15:27:18 2012) and was in 0.7.4
Viewer 3 will discard such a message if the chat message owner does not match the avatar.
We were filling the ownerID with the primID, so this never matched, hence viewer 3 did not see any script error messages.
This commit fills the ownerID in with the prim ownerID so the script owner will receive script error messages.
This does not affect viewer 1 and associated viewers which continue to process script errors as normal.
This is to make it easier to distinguish these exceptions from unexpected OpenSimulator problems internally and in regression tests.
No functional changes.
