Uses new IEntityInventory.TryGetScriptInstanceRunning()
Makes it clearer that TaskInventoryItem.ScriptRunning cannot be used as it is temporary and not updated.
Unlike "save oar", this was happening on the same thread as the original request.
The timeout happens on another so the original thread is never aborted.
On "save oar" this leaves the thread hanging (still bad) but on "save iar" it left the console thread hanging.
Temporary fix is to make "save iar" do asset request on a separate thread, like "save oar".
Longer term fix will be to restructure asset save to use a ManualResetEvent rather than a separate timeout timer.
Viewer 3 will discard such a message if the chat message owner does not match the avatar.
We were filling the ownerID with the primID, so this never matched, hence viewer 3 did not see any script error messages.
This commit fills the ownerID in with the prim ownerID so the script owner will receive script error messages.
This does not affect viewer 1 and associated viewers which continue to process script errors as normal.
Also changes ConsoleUtil.CheckFileExists to CheckFileDoesNotExist() since this is more meaningful in the context, even though it does result in double negatives.
I believe UseCircuitCode is sent on EnableSimulator EQ message, rather than EstablishAgentCommunication
At least with LL 3.3.4, EstablishAgentCommunication appears unnecessary in the teleport context -
viewer still requests it though possibly only after TeleportFinish(). However, we will continue to send it.
The viewer would not see the folder move without this, either on accept or decline.
This commit also updates the TaskInventoryOffered message to better conform with the data LL uses
Changes are, agentID is prim owner rather than prim id, agent name is now simply object name rather than name with owner detail,
message is just folder name in single quotes, message is not timestamped.
However, folder is not renamed "still #RLV/~<name>". Long term solution is probably not to do these operations server-side.
Notes will be added to http://opensimulator.org/mantis/view.php?id=6311
This allows you to display details of all objects in a given bounding box.
Values parts of the co-ord can be left out as appropriate (e.g. to get all objects between the ground and z=30.
See "help show object pos" for more details.
This should really be happening for all console commands (though many don't).
However, things might get difficult if both a console command and other code invoke the same paths.
with wearables. The fact that this hasn't caused problems earlier
suggests either that no one is using multiple layers of wearables or
that this code is useless because the assets are coming in with the
wearables request.
Enables previously disabled regression test.
Based on SingpostMarv's patch in http://opensimulator.org/mantis/view.php?id=6302 but I prefer a simpler approach that does not expose a resume scripts option right now.
This was accidentally introduced in 4fc0cfb
This commit also consistently removes the AssetXferUploader when the transaction completes, no matter if it completed on asset upload or item operation.
The amount of data being retained was small, since this was clothing/bodypart metadata in the asset rather than textures themselves.
This was only used if none of new item, update item or update task item had been set.
But since all transactions go through these paths this old code is redundant.
This was preventing the previous race condition fix in 4fc0cfb from actually working.
This commit also removes some of the pointless transaction id checks - these conditions are already being enforced in AgentAssetsTransactions.
This is done for consistency and to allow removal or some access methods that increase code complexity.
However, this path has not been used for a long time, not even by LL 1.23 - viewers use caps http upload for this instead
On creating these items, the viewer sends a UDP AssetUploadRequest followed by a CreateInventoryItem.
It was possible for the CreateInventoryItem/UpdateInventoryItem to occasionally outrace the AssetUploadRequest and fail to find an initialized Xfer object, at which point the item create would fail.
So instead we always set up a Xfer object on either the asset or inventory item update request.
This does not introduce a new race because code already exists to delay the item operation until the asset is uploaded if necessary (but this only worked if the xfer object already existed)
Make AssetServiceConnector return more useful data on failure, such as what DLL it was trying to load
Allow LocalAssetServiceConnector.GetData() to work without a cache present, as works for the other lasc Get* methods.
This is to resolve a problem where an asset marked as local but not temporary but still used in the scene would be removed.
The timed expiry scan no longer tries to refetch assets from the scene that are not currently in the cache - this is not helpful since it just drags a lot of data into the cache that may never be referenced.
This removes the DeepScanBeforePurge option since setting this to false will introduce the above problem. This previously had a default of true.
Merged ArchiveWriteRequestPreparation.cs and ArchiveWriteRequestExecution.cs. This simplifies the code, and it's faster to write each scene to the archive as it's found rather than all at once at the end.
Move the addin information from attributes in the source file to the CoreModulePlugin.xml, which is the standard. This will help us automate addin version dependency information when we make new OpenSim releases.
Manually calling GC.Collect() really shouldnt' be necessary and is generally regarded as a bad idea.
A GC should occur anyway pretty shortly afterwards.
However, can leave this in development code for now to see if it does actually make a significant difference rather than simply doing a GC a little earlier.
Viewer LL 3.3.4 and before sometimes fail to properly redisplay dynamic textures that have a small data length compared to pixel size when pulled from cache.
This appears to happen when the data length is smaller than the estimate discard level 2 size the viewer uses when making this GetTexture request.
This commit works around this by always regenerating dynamic textures that fall below this threshold rather than reusing them if ReuseDynamicTextures = true
This can be controlled by the [Textures] ReuseDynamicLowDataTextures config setting which defaults to false.
This is because recent viewers (3.2.1, 3.3.4) and probably earlier ones using the http GetTexture capability will sometimes make such invalid range requests.
This appears to happen if the viewer's estimate of texture sizes at discard levels > 0 (chiefly 2) exceeds the total texture size.
I believe this does not normally happen but can occur for dynamic textures with are large but mainly blank.
If this happens, returning a RequestedRangeNotSatisfiable will cause the viewer to not render the texture at the final resolution.
However, returning a PartialContent (or OK) even with 0 data will allow the viewer to render the final texture.
If true, this setting reuses dynamically generated textures (i.e. created through osSetDynamicTextureData() and similar OSSL functions) where possible rather than always regenerating them.
This results in much quicker updates viewer-side but may bloat the asset cache (though this is fixable).
Also, sometimes issue have been seen where dynamic textures do not transfer to the viewer properly (permanently blurry).
If this happens and that flag is set then they are not regenerated, the viewer has to clear cache or wait for 24 hours before all cached uuids are invalidated.
CUrrently experimental. Default is false, as before.
type for an HTTP request. Since the "official" LSL function limits
the use of the response type, it is implemented as osSetContentType
with a string for the content mime type and a threat level of high.
With this function you should be able to implement rather functional
media-on-a-prim application with much less difficulty.
This prevented more than one additional ordinary folder from being created in the base "My Inventory" user folder.
Added regression test for this case.
Switched tests to use XInventoryService with mostly implemented TestXInventoryDataPlugin rather than InventoryService
Disabled TestLoadIarV0_1SameNameCreator() since this has not been working for a very long time (ever since XInventoryService) started being used
since it doesnt' preserve creator data in the same way as InventoryService did and so effectively lost the OSPAs.
However, nobody noticed/complained about this issue and OSPAs have been superseded by HG like creator information via the --home save oar/iar switch.
Disabled (status quo) by default.
This flag makes the dynamic texture module reuse cache previously dynamically generated textures given the same input commands and extra params for 24 hours.
This occurs as long as those commands would always generate the same texture (e.g. they do not contain commands to fetch data from the web).
This makes texture changing faster as a viewer-cached texture uuid is sent and may reduce simulator load in regions with generation of lots of dynamic textures.
A downside is that this stops expiry of old temporary dynamic textures from the cache,
Another downside is that a jpeg2000 generation that partially failed is currently not regenerated until restart or after 24 hours.
In testing, it appears that if multiple threads dispose of separate GDI+ objects simultaneously,
the native malloc heap can become corrupted, possibly due to a double free(). This may be due to
bugs in the underlying libcairo used by mono's libgdiplus.dll on Linux/OSX. These problems were
seen with both libcario 1.10.2-6.1ubuntu3 and 1.8.10-2ubuntu1. They go away if disposal is perfomed
under lock.
If a group UUID is present that is not on this simulator then the object or parcel is no longer group owned.
This is a change from previous behaviour where such invalid UUIDs were kept.
This is an adaptation of patch 0002 from http://opensimulator.org/mantis/view.php?id=6105 by Oren Hurvitz of Kitely.
My adaptations are formatting only, apart from the notices about parcel owner IDs not being saved since this has now been fixed.
Thanks Oren.
This is to allow a second attempt to remove an avatar even if "show connections" shows them as already inactive (i.e. close has already been attempted once).
You should only attempt --force if a normal kick fails.
This is partly for diagnostics as we have seen some connections occasionally remain on lbsa plaza even if they are registered as inactive.
This is not a permanent solution and may not work anyway - the ultimate solution is to stop this problem from happening in the first place.
This was working in 0.7.2 but was accidentally removed from 0.7.3.
The --publish option for "save oar" will now save oars stripped of parcel owner information as well as scene object info.
Please use the --publish option if you want to publish oars that may be later loaded by others to the same grid from which they were saved.
The bug manifested as follows: a large world was saved. All the assets were found. But for some unknown reason, the timeout timer was restarted. So after 1 minute it closed the Archive Writer, because it didn't receive any more assets during that minute. That caused the OAR to become corrupted because ArchiveWriteRequestExecution.Save() was still running.
The convention is that if an object implements IDiposable() the code must explicitly call Dispose() or call it via the using statement.
This may be particularly important for GDI+ objects since they encapsulate native code entities.
If we copy the asset description then we will only ever replicate the very first description, if there was one, not any subsequent changes.
Thanks to Oren Hurvitz of Kitely for this patch from http://opensimulator.org/mantis/view.php?id=6107
I have adapted it slightly to change the order of arguments (name before description rather than vice-versa) and slightly improve some method doc.
This is fired when all regions are ready or when at least one region becomes not ready.
Recently added EventManager.OnRegionReady becomes OnRegionReadyStatusChange to match OnLoginsEnabledStatusChange
justincc's original work. Sample scripts before doing so. Also refactor some
crucial common code and eliminate parameters that were only ever used with
the same constant value.
This replaces EventManager.OnLoginsEnabled which only fired when logins were first enabled
and was affected by a bug where it would never fire if the region started with logins disabled.
This saves listeners from having to re-retrieve the scene from their own lists, which won't work anyway if multiple regions with the same name have been allowed
This appears to be a regression from back in commit db91044 (Mon Aug 22 2011) where we started to send TaskInventoryOffered msg dialog rather than InventoryOffered dialog.
This is probably correct, but failed because the bucket was too large and because we wouldn't have handled the TaskInventoryDeclined option anyway.
This patch handles both of these and make llGiveInventoryList() use TaskInventoryOffered as well
Fixes http://opensimulator.org/mantis/view.php?id=6089
Note, this behaviour appears to be at variance with the ll grid as of Tues 17 July 2012, testing with viewer 3.2.1.
The item name in inventory does not change either at the point of detach or after a relog.
This doesn't seem to make any sense and probably stems from a period when this code was directly involved in attaching objects directly from the scene.
This message is already being sent by InventoryAccessModule code instead.
The encodings are thread-safe and already used in such a manner in other places.
This isn't done where Byte Order Mark output is suppressed, since Encoding.UTF8 is constructed to output the BOM.
This is only currently meant for use by regression tests that don't have any issues if XEngine is started up quickly, since no other operations will be occuring simultaneously.
Therefore, this is not yet documented externally.
This is to fix a regression starting from 5301648 where attachments had to start being deleted before persistence in order to avoid race conditions with hud update threads.
This prevents a stack overflow where a get position on the avatar will refer to the attachment which will in turn refer back to the avatar.
This required recording of all sitting avatars on a prim which is done separately from recording the sit target avatar.
Recording HashSet is null if there are no sitting avatars in order to save memory.
This was causing 2 copies of the module to be created for each scene.
Probably no bad consequences other than a small waste of memory (both for the module and for the warp3D renderer it loaded)
This works like osForceAttachToAvatar() but allows an object to be directly specified from the script object's inventory rather than forcing it to be rezzed in the scene first.
Still only attaches objects to the owner of the script.
This allows one to bypass the complicated co-ordination of first rezzing objects in the scene before attaching them.
Threat level high.
null would only ever be returned if the item couldn't be located within inventory and this would happen immediately.
In this case, derezzing wouldn't work anyway since there is no item to derez.
This matches behaviour in fatpack crossing, where attachments are cloned before their properties are changed.
This only applies to crossings to simulators running code released before April 2011.
If delete doesn't occur first then the update thread can outrace the IsAttachment = false necessary to save attachments and send hud artifacts to other viewers.
Serialization of attachments requires IsAttachment = false so that correct positions are serialized instead of avatar position.
However, doing this when a hud is still attached allows race conditions with update threads, resulting in hud artifacts on other viewers.
This change sets SOG.IsDeleted before serialization changes take place (IsDeleted itself is not a serialized property).
LLClientView then screens out any deleted SOGs before sending updates to viewers.
This involves three steps
1) Return gracefully in UrlModule.HttpRequestHandler() instead of throwing an exception when the url cannot be found in its index
2) Return true instead of false in HasEvents() if no matching request is found in the map. This call will only happen in the first place for raced requests.
3) Return a 404 in GetEvents() if the request is not in the index, rather than a blank 200 OK.
Many thanks to Tom Haines in http://opensimulator.org/mantis/view.php?id=6051 for doing some of the work on this.
Previously, setting IsAttachment to false then true was necessary to serialize the updated attachment object information.
However, UpdateAttachmentPosition no longer does this update.
Whilst IsAttachment is set to false there is a race condition where the update thread can wrongly send hud object updates to clients that do not own the hud, resulting in screen artifacts.
It's a valid configuration not to have these modules, but I think it's still worth logging the fact that certain permissions won't work (always return true)
Change SOP.SendFullUpdateToClient() and SoundModule.PlayAttachedSound() to use this rather than different magic number formulations.
This also corrects a bug in PlayAttachedSound() where the code assumed that all attachment points over 30 were HUDs.
It appears this is no longer true with Neck and Root (Avatar Center)
Stop checking IsLoggingOut on these listeners, if called with a root agent then we always want to perform these actions.
This covers cases where the client is closed due to manual kick, simulator shutdown, etc.
This is always done as part of Scene.RemoveClient()
Also refactors try/catching in Scene.RemoveClient() to log NREs instead of silently discarding, since these are useful symptoms of problems.
If active, the physics module can return arbitrary stat counters that can be seen via the MonitoringModule
(http://opensimulator.org/wiki/Monitoring_Module)
This is only active in OdeScene if collect_stats = true in [ODEPhysicsSettings].
This patch allows OdeScene to collect elapsed time information for calls to the ODE native collision methods to assess what proportion of time this takes compared to total physics processing.
This data is returned as ODENativeCollisionFrameMS in the monitoring module, updated every 3 seconds.
The performance effect of collecting stats is probably extremely minor, dwarfed by the rest of the physics code.
Also fixes the log warning from ResetInTransit() if the state is cleared direct from Transferring or ReceiveAtDestination, as pointed out in mantis 5426
If this is allowed, then the client usually gets forcibly logged out and data structures might be put into bad states.
To prevent this, the binary state machine of EMT.m_agentsInTransit is replaced with a 4 state machine (Preparing, Transferring, ReceivedAtDestination, CleaningUp).
This is necessary because the source region needs to know when the destination region has received the user but a teleport back cannot happen until the source region has cleaned up.
Tested on standalone, grid and with v1 and v3 clients.
This is to help relieve a race condition when an agent teleports then immediately attempts to teleport back before the source region has properly cleaned up/demoted the old ScenePresence.
This is rare in viewers but much more possible via scripting or region module.
However, more needs to be done since virtually all clean up happens after the transit flag is cleared .
Possibly need to add a 'cleaning up' state to in transit.
This change required making the EntityTransferModule and HGEntityTransferModule per-region rather than shared, in order to allow separate transit lists.
Changes were also required in LocalSimulationConnector.
Tested in standalone, grid and with local and remote region crossings with attachments.
This includes prim count, script count, avatar count, etc.
Information is currently the same as "show stats", though show stats can only show one scene at a time because it listens for the latest outgoing stats packet (a bad approach that needs to change).
Might be better to tie this module into the other stats module to display arbitrary stats rather than fetching directly from scene.SimStatsReporter.
Console command is "show scene" because "show region" already exists for the grid service, which is unfortunate.
Might need to make a distinction between "scene" relating to a live scene and "region" relating to more static region data (url, coords, etc.)
The reference is not guaranteed to be there when AddRegion() is called but will definitely be present at RegionLoaded() if it's going to be present at all.
This is because the attachments module code was setting the 'object slam' bit by using PermissionMask.All
Solution here is to route the attachment item creation call through the existing inventory code in BasicInventoryAccessModule rather than copy/pasted code in AttachmentsModule itself.
This is to eliminate possible race conditions if two teleport calls are made concurrently, where at least one is a local teleport.
This is pretty much impossible on a manual user teleport but can happen on script-invoked teleports.
An adaptation of part of Garmin's patch from http://opensimulator.org/mantis/view.php?id=5975, thanks!
Flag only written if the SW corner OAR is saved - this is the only one that captures object data presently (though not land or terrain data).
This adds an IRegionCombinerModule interface and the necessary methods on RegionCombinerModule
This was because the parts in scene objects were sometimes not serialized in link order.
This is perfectly fine since the parts still have the right link numbers, but an extra fix to adjust for this
had not been done in the SerialiserModule methods that OAR loading used.
Add regression test for same.

On EntityTransferModule.DoTeleport() there was an IsInTransit() check to prevent multiple simultaneous teleport attempts.
However, the SetInTransit() was only performed later on, which left a window in which multiple threads could pass the IsInTransit() check.
This has been seen in the field and the results aren't pretty.
This commit effectively combines the IsInTransit() and SetInTransit() checks so there is no such window.
More failure cases are made to to call ResetInTransit() to adjust to this move.
This reverts commit b0b7b45b94.
Sorry BlueWall, I wanted to discuss an aspect of the data storage but I couldn't assign bugs in 'patch included' state to myself until I changed mantis just now and I forgot to mention it on irc.
I wouldn't normally revert but thinks get tricky when it comes to data formats.
Essentially, I would like to see the Yaw, Pitch and Distance values as separate XML entities (as used in other aspects such as vectors, quaternions) rather than as a . delimited string
We can discuss this more with Oren in opensimulator.org/mantis/view.php?id=6008
Viewers 1 and 3 are fine with doing this immediately. However, Imprudence has a small delay (<200ms, >500ms) after receiving the AgentCompleteMovement reply packet on the destination region before regarding that region as the currnet region.
If Imprudence receives a DisableSimulator in this period, it quits.
We are not restoring the full 5000ms delay since this brings back a bug where teleports permanently fail if an avatar tries to teleport back too quickly.
This commit also sends the AgentCompleteMovement packet to the client before telling the source region to release its old agent, in order to further cut down any possibility of the DisableSimulator being recieved before the AgentMovementComplete.
This sleep appears unnecessary since a sleep has already occurred in WaitForCallback() whilst waiting for the destination region to notify of teleport success.
There are no async operations between this sleep and the WaitForCallback()
If this sleep is present, then teleporting back to the source region within 5 seconds results in a disconnection.
If this sleep is commented out then teleporting quickly back and forth between two simulators appears to work without issue.
Tested on standalone, local grid and distributed grid.
Please revert if there's something that I've missed.
This adds a non-advertised wait_for_callback option in [EntityTransfer]. Default is always true.
Teleport tests disable the wait for callback from the destination region in order to run within a single thread.
This involves a large amount of change in test scene setup code to allow test scenes to share shared modules
SetupScene is now an instance method that requires an instantiation of SceneHelpers, though other SceneHelpers methods are still static
May split these out into separate classes in the future.
Permanently comment out warnings about ScenePresence not being found - this is entirely expected if the avatar has alraedy logged out or left the scene.
This was an oversight when removing some race conditions from PhysicsActor setting recently.
Regression tests extended to probe this code path.
Extending regression tests required implementation of a BasicPhysicsPrim (there was none before). However, BasicPhysics plugin is still of no current practical use other than to fill in as a component for other parts of regression testing.
This involves giving the ceiling of the Z-component in a lure rather than the floor.
Ideally we would give the exact float compensating for relative avatar height but it looks like that isn't possible with the parcel id format used in lures
This replaces the Parts count which was rather pointless for a prim (it was either 1 if a child or the number of parts if the root).
This information is still avaliable on the "show object" command.
This makes it consistent with other parts of OpenSimulator that are treating ESTATE_MANAGER and ESTATE_OWNER as different entities.
As per opensim-dev mailing list.
Use existing cache if the avatar is within the region and use an
ExpiringCache to cache status if the avatar is not in the region. The
30 second delay now applies to scripted objects ony and only when the owner
is not present.
Another thread could come and turn off physics for a part (null PhysicsActor) at any point.
Had to turn off localCopy on warp3D CoreModules section in prebuild.xml since on current nant this copies all DLLs in bin/ which can be a very large number with compiled DLLs
No obvious reason for doing that copy - nothing else does it.
Rename IFriendsModule.GetFriendPerms() -> GetRightsGrantedByFriend() to be more self-documenting and consistent with friends module terminology.
Add some method doc.
This adds ScenePresence to IClientAPI.SceneAgent earlier on in the add client process so that its information is available to EventManager.OnNewClient() and OnClientLogin()
Also add a code comment as to why we're caching friend information for child agents.
We need to cache child agents so that friends object edit/delete permissions will work across boarders on regions hosted by different simulators.
This reverts commit d9f7b8549b.
This allows us to avoid unnecessary multiple calls to the friends service.
All friends functions originate from the root agent and only go to other root agents in existing code.
This also allows us to eliminate complex ref counting.
Unfortunately, the OnLoginsEnabled event is currently only guaranteed to fire if the RegionReady module is active.
However, we can instantiate the AuthorizationService in the module RegionLoaded method since by this time all other modules will have been loaded
The previous lines-per-second measurement used for top scripts report was inaccurate, since lines executed does not reflect time taken to execute.
Also, every fetch of the report would reset all the numbers limiting its usefulness and we weren't even guaranteed to see the top 100.
The actual measurement value should be script execution time per frame but XEngine does not work this way.
Therefore, we use actual script execution time scaled by the measurement period and an idealised frame time.
This is still not ideal but gives reasonable results and allows scripts to be compared.
This commit moves script execution time calculations from SceneGraph into IScriptModule implementations.

- 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.
This is to deal with the hundred lines of command splurge when one previously typed "help"
Modelled somewhat on the mysql console
One can still type help <command> to get per command help at any point.
Categories capitalized to avoid conflict with the all-lowercase commands (except for commander system, as of yet).
Does not affect command parsing or any other aspects of the console apart from the help system.
Backwards compatible with existing modules.
I believe this was originally required back when there could be two LocalGridServiceConnectors but this is no longer the case.
Having such statics makes performance testing much more difficult since they prevent GC of objects unless static references are explicitly nulled.
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

Feedback and discussion welcome as commits are made.
On the first frame, all startup scene objects are added to the physics scene.
This can cause a considerable delay, so we don't start raising the alarm on scene loop timeouts until the second frame.
This commit also slightly changes the behaviour of timeout reporting.
Previously, a report was made for the very first timed out thread, ignoring all others until the next watchdog check.
Instead, we now report every timed out thread, though we still only do this once no matter how long the timeout.
This involves
1) On forcible teleport, call m_scene.RequestTeleportLocation() rather than ScenePresence.Teleport() - only EntityTransferModule now should call SP.Teleport()
2) When avatar is being forcibly moved due to banlines, use a 'stop movement' tolerance of 0.2 to requested position rather than 1
This prevents the avatar sometimes being stuck to banlines until they teleport somewhere else.
This aims to fix some problems in http://opensimulator.org/mantis/view.php?id=5822
potential bad update that places an object at the opposite side of the
origin sim for a moment before actually crossing it. Especially important in
grids like OSG where lag between sims is high.
This fixes the problem by fixing the permissions module to look at root part permissions rather than having to do this for every caller.
