* Fix a problem where multiple near simultaneous calls to llDie() from ↵Justin Clark-Casey (justincc)2012-03-152-20/+10
| | | | | | | | | | multiple scripts in the same linkset can cause unnecessary thread aborts. 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.
* Alleviate an issue where calling Thread.Abort() on script WorkItems can fail ↵Justin Clark-Casey (justincc)2012-03-152-4/+15
| | | | | | | | | | to release locks, resulting in a crippled simulator. 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.

| * Rename the stream extension method WebUtil.CopyTo() to WebUtil.CopyStream().Robert Adams2012-03-124-4/+9
| | | | | | | | | | | | | | | | | | | | .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.

| * Add ability to specify a default estate to be used when creating regions.Justin Clark-Casey (justincc)2012-03-102-67/+171
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | (saving extra null checks, etc.) 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some successful collision attacks have been carried out on sha1 with speculation that more are possible. http://en.wikipedia.org/wiki/Cryptographic_hash_function#Cryptographic_hash_algorithms No successful attacks have been shown on sha256, which makes it less likely that anybody will be able to engineer an asset hash collision in the future. Tradeoff is more storage required for hashes, and more cpu to hash, though this is neglible compared to db operations and network access.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an extremely crude implemenation which almost works by accident. Nevertheless it does work. It can be tested with the instructions at http://opensimulator.org/wiki/Feature_Proposals/Deduplicating_Asset_Service#Testing It does not interact at all with the existing asset service or any data stored there. This code is subject to change without notice and should not be used for anything other than gawking.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the start of exploring the creation of a bundled OpenSimulator asset service that does de-duplication and possibly file storage of assets. Along the lines of coyled's SRAS, but not intended to replace, merely to act as a more performant bundled default. Might end up nicking stuff from kcozen's patch at http://opensimulator.org/mantis/view.php?id=5429 More details at http://opensimulator.org/wiki/Feature_Proposals/Deduplicating_Asset_Service Feedback and discussion welcome as commits are made.
