As far as I can see, this is only invoked by a PUT request to ObjectHandlers, which is not being used anyway.
Invoking attachments code at this point is probably inappropriate since it would still be invoked when the client entered the scene.
Being commented to simplify analysis of attachments issues. Can be uncommented when in use.
Also, small tweak to lock and log removal of a SOG from the SceneObjectGroupsByLocalPartID collection in SceneGraph.GetGroupByPrim() if an inconsistency is found.
This is the message sent to the client when the object is returned.
We were sending byte[0] in the binary bucket. This didn't kill viewer 1 but did terminate viewer 3 (don't know about viewer 2).
So sending "\0" instead.

Attach and detach packets are processed asynchronously when received from a viewer.
Bugs like http://opensimulator.org/mantis/view.php?id=5644 indicate that in some situations (such as attaching/detaching entire folders of objects at once), there are race conditions between these threads.
Since multiple data structures need to be updated on attach/detach, it's not enough to lock the individual collections.
Therefore, this commit introduces a new IScenePresence.AttachmentsSyncLock which add/remove operations lock on.
Leaving them at UUID.Zero meant that when a viewer 2 logged into a region that had been freshly created, it received UUID.Zero for these textures, and hence display the land as plain white.
On a simulator restart, the problem would go away since when the database adapators loaded the new region settings, RegionSettings itself has code to use default textures instead of UUID.Zero.
This commit resolves the problem by saving the default texture UUIDs instead of Zero.
However, we currently have to do this in a roundabout way by resaving once the RegionSettings have been created by the database for the first time. This needless complexity should be addressed.
This change will also have the effect of replacing any existing UUID.Zero terrain textures with the default ones.
However, this shouldn't have any effect since the UUID.Zeros were already being replaced in memory with those same UUIDs.
This is to prevent the aborting of attachment script threads on teleport from aborting the one actually doing the teleport.
This allows OSSL teleport functions to work when invoked on scripts in attachments (and huds, I assume)

However, if this failure was happening I'm kind of surprised that local HG inventory was working at all.....
We probably weren't seeing these exceptions previously because we weren't logging them when the reached the top of a FireAndForget thread.
This is for http://opensimulator.org/mantis/view.php?id=5669
If we can't retrieve an IUserManagement module we complain, and we also warn in the log when its manually set in XISC by HGInventoryBroker
This is only called by a region console command.
We should also be locking m_partsUpdateQueue when dequeueing the next part, or locking m_pendingObjects in QueuePartForUpdate().
However, I won't do this now since I don't have time to analyze how this would affect liveness.
Strictly speaking, we could also stop bothering to clear the m_updateTimes and m_partsUpdateQueue if we are sure that the whole SceneViewer is shortly to be garbage collected anyway, but we'll leave them around for now.
When a user logs in, the attachment item ids are pulled from persistence in the Avatars table. However,
the asset ids are not saved. When the avatar enters a simulator the attachments are set again. If
we simply perform an item check then the asset ids (which are now present) are never set, and NPC attachments
later fail unless the attachment is detached and reattached.
Hopefully resolves part of http://opensimulator.org/mantis/view.php?id=5653
The code in question is over three years old and just be catching an inconsistency rather than being wholly necessary.
This commit still carries out the check and prints all the previous log warnings but a 'failure' no longer prevents avatar region crossing or teleport, and it doesn't give the client the error message.
This will have some kind of impact on http://opensimulator.org/mantis/view.php?id=5672
Not doing this causes NREs whenever that user tries to access inventory when Hypergrid is turned on since the Remote connector does not have a scene (which is only used to fetch the UserManager)
Aims to address http://opensimulator.org/mantis/view.php?id=5669
This was happening because we were using the source avatar's item IDs in the clone appearance.
Switch to using the asset IDs of attachments instead for NPCs.
The InventoryAccessModule and AttachmentModule had to be changed to allow rezzing of an object without an associated inventory item.
Hopefully goes some way towards resolving http://opensimulator.org/mantis/view.php?id=5653
