This is handled by treating UUID.Zero as a special case.
Currently, asking for the "none" group returns nothing because XMLRPC groups, at least, is not properly handling this case.
It may be better in the future to have GroupsModule return an appropriate GroupsData structure instead or require the underlying services to behave appropriately.
This is a further component of http://opensimulator.org/mantis/view.php?id=5588
There were two problems here:
1) On object group update, we looked for the group is the IClientAPI group cache rather than in the groups service. This fails to groups created newly in that session
2) On object group update, we weren't setting the HasGroupChanged flag. This meant that the change was not persisted unless some other action set this flag.
This commit fixes these issues and hopefully addresses http://opensimulator.org/mantis/view.php?id=5588
This commit also moves HandleObjectGroupUpdate() to the GroupsModule from the Scene.PacketHandlers.cs file
The caller is already an async thread from LLClientView so this doesn't hold up the client.
However, launching on a separate thread does remove the effect of m_setAppearanceLock
This was potentially allowing two different SetAppearance threads to interfere with each other, though this probably rarely happens, if at all.
This prints out both exception message and stacktrace (Exception.ToString()) isn't enough on Windows.
This also uses m_log.*Format() which is more efficient than string concat.
The only caller is the LLUDP stack and this has to validate the UDP circuit itself, so we know that it exists.
This allows us to eliminate another null check elsewhere and simplifies the method contract
This means that avatar/appearance data of other avatars and scene objects for a client will be sent after the ack rather than possibly before.
This may stop some avatars appearing grey on login.
This introduces a new OpenSim.Framework.ISceneAgent to accompany the existing OpenSim.Framework.ISceneObject and ISceneEntity
This allows IClientAPI to handle this as it can't reference OpenSim.Region.Framework.Interfaces
If sp becomes null right after we've checked or created it, then behaviour down the line is going to be wrong anyway.
So instead retain the check/create ScenePresence reference and use this.
It makes far more sense anyway to use TryGetRootScenePresence().Scene, in common with the rest of the code
This method could also return any scene for child or root agents, depending in which order the scenes happened to lie in the list
Also adds password check to some functions where this was missing and fixes some parameter checking.
This is a patch from http://opensimulator.org/mantis/view.php?id=5715 with a few small unrelated spacing tweaks from me.
Thanks Michelle Argus.
This meant that if a user exited the region, the UploadTexture handler would be effectively removed for everyone, causing subsequent failures.
This hopefully resolves the recent UploadTexture LLSD problems
