The separate remove and set operations is SOG.set_UUID() are both locked under m_parts.SyncRoot since they are logically atomic (though this isn't such an issue if the SOG isn't part of a scene)
Added unit test for this behaviour.
Also changed the second m_parts.AddOrReplace() to m_parts.Add(). As the old reference is now removed we never end up replacing an identical uuid. And if we replace a uuid that's already there (from a child part) then this is an error.
Previously, deadlock was possible because deleting a group took a SOG.Children lock then an m_entityUpdates.SyncRoot lock in LLClientView
At the same time, a thread starting from LLClientView.ProcessEntityUpdates() could take an m_entityUpdates.SyncRoot lock then later attempt to take a SOG.Children lock in PermissionsModule.GenerateClientFlags() and later on
Taking a children list in SOG appears to be a better solution than changing PermissionsModule to not relook up the prim. Going the permission modules root would require that all downstream modules not take a SOG.Children lock either
* Removed StorageManager
* CONFIG CHANGE: There are no more database settings in OpenSim.ini. Check the config-include configuration files for region store and estate store database settings
Previously, Scene.Inventory.DeRezObjects() forced the persistence of prims before deletion.
This is necessary so that freshly delinked prims can be deleted (otherwise they remain as parts of their old group and reappear on server restart).
However, DeRezObjects() deleted to user inventory, which is required by llDie() or direct region module unlink and deletion.
Therefore, forced persistence has been pushed down into Scene.UnlinkSceneObject() to be more general, this is still on the DeRezObjects() path.
Uncommented TestDelinkPersistence() since this now passes.
Tests required considerable elaboration of MockRegionDataPlugin to reflect underlying storing of parts.
Added a MockRegionDataPlugin to do in-memory persistence for tests since adding this to OpenSim.Data.Null.NullDataStore doesn't seem appropriate
NullDataStore can do nothing because OpenSim only ever retrieve region objects from the database on startup. Adding an in-memory store here would be unecessary overhead.
nonworking ownership assignment in SOG, which messed things up before.
No longer trust the client to send the ID of the person something is copied
as, since it allows to run a script with someone else's permissions. Properly
adjust inventory ownership and perms.
This is one step towards reducing hud glitches on region crossing, since the viewer fails to display prims if it receives child full updates before the root prim full update
This commit also introduces a mechanism in LLClientView to stop child attachment updates ever going out before the root one
This is a very temporary mechanism and will be commented out when the next step of the fix (to give root prims higher udpate priority) is committed
This code is a foreport from the equivalent changes in 0.6.9-post-fixes
* Simplified the interest management code to make it easier to add new policies. Prioritization and reprioritization share code paths now
* Improved the distance and front back policies to always give your avatar the highest priority
This patch also applies a fix to Combat/CombatModule.cs which had unlocked iteration of the ScenePresences and inconsistent try/catch around the use of those ScenePresences.
The root cause of this problem was that multiple ObjectUpdates were being sent on attachment which differed enough to confuse the client.
Sometimes these would eliminate each other and sometimes not, depending on whether the scheduler looked at the queued updates.
The solution here is to only schedule the ObjectUpdate once the attachment code has done all it needs to do.
Fixes: Undo, T-pose of others on login, modifiedBulletX works again, feet now stand on the ground instead of in the ground, adds checks to CombatModule. Adds: Redo, Land Undo, checks to agentUpdate (so one can not fall off of a region), more vehicle parts. Finishes almost all of LSL (1 function left, 2 events).
