from region modules. The LSL translator is extended to generate the
modInvoke format of commands for directly inlined function calls.
A region module can register a function Test() with the name "Test".
LSL code can call that function as "Test()". The compiler will translate
that invocation into modInvoke("Test", ...)
The first llDie() could lock Scene.m_deleting_scene_object.
The second llDie() would then wait at this lock.
The first llDie() would go on to remove the second script but always abort it since the second script's WorkItem would not go away.
Easiest solution here is to remove the m_deleting_scene_object since it's no longer justified - we no longer lock m_parts but take a copy instead.
This also requires an adjustment in XEngine.OnRemoveScript not to use instance.ObjectID instead when firing the OnObjectRemoved event.
This seems to be a particular problem with ReaderWriterLockSlim, though other locks can be affected as well.
It has been seen to happen when llDie() is called in a linkset running more than one script.
Alleviation here means supplying a ScriptInstance.Stop() timeout of 1000ms rather than 0ms, to give events a chance to complete.
Also, we check the IsRunning status at the top of the ScriptInstance.EventProcessor() so that another event doesn't start in the mean time.
Ultimately, a better solution may have to be found since a long-running event would still exceed the timeout and be aborted.
.NET 4.0 added the method Stream.CopyTo(stream, bufferSize). For .NET 3.5
and before, WebUtil defined an extension method for Stream with the signature
Stream.CopyTo(stream, maxBytesToCopy). The meaning of the second parameter
is different in the two forms and depending on which compiler and/or
runtime you use, you could get one form or the other. Crashes ensue.
This change renames the WebUtil stream copy method to something that
cannot be confused with the new CopyTo method defined in .NET 4.0.
This is configured in the new [Estates] section of OpenSim.ini.
If a default estate is configured then all new regions are automatically joined to it instead of asking the user.
If the default estate does not already exist then it is created.
Current default behaviour remains the same - the user is asked for estate details when necessary.
Thanks to Frenando Oliveira for the patch which I adapated further.
- Added an inventory cache for caching root and system folders
- Synchronized the remote inventory connector, so that all the remote inventory calls are serialized
This will not make much difference in the hold ups. We'd have to move the FireAndForget high up to AddInventoryItem, but that opens up a can of worms regarding the notification of the recipient... the recipient would be notified of the offer before the items are effectively in his inventory, which could lead to surprises.
However, it looks like we should retain SP.ParentID since it's much easier to use that in places where another thread could change ParentPart to null.
Otherwise one has to clumsily put ParentPart in a reference, etc. to avoid a race.
