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.
This is to provide an indication of what's happening now that the default isn't to report every single script start.
Changes XEngine logging level in OpenSim.exe.config from WARN to INFO.
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)
Also removes superflous Close() commands for statements taking place within using() constructs
Also adds some comment out debug log messages for future use.
Accidentally make responseString null by default instead of String.Empty.
It needs to be something in case the XmlRpcRequest deserialize throws an exception due to bad xml (a failure which we silently swallow!)
If this happens, then the non-owners would see unremovable huds that they did not own until relog, and sometimes even beyond that.
This was due to a race between the entity update and the attachment code when moving an object from within scene to a hud.
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)
This is to avoid logging a 'slow' request when the source of delay is the viewer in processing a response.
This is not something we can do much about on the server end - it's server-side delay that we're interested in.
To ensure consistency, this commit also had to refactor and simplify inbound non-poll network request handling, though there should be no functional change.
IOSHttpResponse no longer exposes the Send() method, only classes in OpenSim.Framework.Servers.HttpServer should be doing this.
Only the GetTextureHandler was sending its own response. Now it leaves this to BaseHttpServer, like all other core handlers.
Added "timer_Interval" to the OpenSimDefaults.ini, leaving the default value set to 1200, as the previous default setting. The value represents seconds. To change the default, copy the entry to OpenSim.ini and multiply the number of minutes for the interval by 60.
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.
IsActive is more appropriate since unack timeout is not due to voluntary logout.
This is in line with operations such as manual kick that do not set the IsLoggingOut flag.
It's also slightly better race-wise since it reduces the chance of this operation clashing with another reason for client deactivation (e.g. manual kick).
llTeleportAgentGlobalCoords. These do NOT use PERMISSION_TELEPORT like
their SL counterparts because that permission is not yet understood by TPVs
based on v1.x.
This is the same async behaviour as normal logouts.
This is necessary because the event queue will sleep the thread for 5 seconds on an ack timeout logout as the client isn't around to pick up the final event queue messages.
Instead of checking whether the client still exists by trying to retrieve again from the client manager, this patch gets it back from IncomingPacket and checks the IClientAPI.IsActive state.
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.
This is done by making the kick user command call IClientAPI.Close() rather than routing through Scene.IncomingCloseAgent(), which also called IClientAPI.Close()
DisableSimulator for child agents is moved from IncomingCloseAgent() to RemoveClient(), this is not a functional change since IncomingCloseAgent() always ends up calling RemoveClient()
This alarm can then invoke this to log extra information.
This is used in LLUDPServer to show which client was being processed when incoming and outgoing udp watchdog alarms are triggered.
Adapted from a patch by Garmin Kawaguichi in http://opensimulator.org/mantis/view.php?id=6027
Garmin says that fix-phantoms allows one to reset objects when going back from megaregion to normal regions as well as the othe rway around.
Thanks!
The packet was actually being handled but not acted on.
This change extends the default timeout for paused clients to 5 minutes
and makes both the paused and non-paused timeout periods configurable.
This makes frame time stats properly tally with fps, which saves confusion and makes it easier to interpret numbers.
In some ways this is not so artifical - physics FPS runs at the higher rate.
This is to make these statistics actually match their names (and also be more accurate as number of frames can vary under heavy load)
Currently using scene frames (11.23 every second) instead of physics frames (56.18 per second)
1) The return messages were being wrongly populated with the names of asset, inventory and sale types when their corresponding integers should have been used instead.
2) Folders with links were including the linked items in the descendents figure, when only the links should be included.
3) Links and linked items in link folders were not being included in the return data, and not in the correct order.
Now that these issues have been addressed, outfits and attachments appear to work consistently when HTTP inventory is enabled (as is now the default).
These will act as a sanity check with the main scene stats, to show that physics scene entities are being managed properly.
Total prims will not match scene total prims since physics total does not include phantom prims
Also zeros collisions scores on all prims after report collection, not just the top 25.
As before, this collision scores are only reset after a report is requested, which may give unrealistic numbers on the first request.
So to see more realistic scores, ignore the first report and then refresh the request after a couple of seconds or so.
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 the script requesting permissions is owned by either the NPC or
the NPCs owner (if the NPC is created as owned) then grant any
permissions automatically.
If this is done before then on ODE agent update calls still incoming can fail as they try to use a raycastmanager that has been disposed.
Bullet plugin does nothing on Dispose()
However, I wouldn't be at all surprised if individual region restarting was buggy in lots of other areas.
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 was due to two things
1) SimulationServiceConnector.QueryAccess was always looking to the outer result["success"].
But if a "_Result" map is returned (which is certainly the case right now), then the true success is _Result["success"], result["success"] is always true no matter what
2) If QueryAccess was false at the destination, then AgentHandlers.DoQueryAccess() was never putting this in the result.
The default action of SerializeJsonString() is not to put false booleans in the JSON!!!, so this has to be explicitly set.
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.
This was previously over-inflated because adding a region to the NE of the root region resulted in double counting of regions already added.
An accurate extent will also be necessary for other purposes.
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
Since this is done directly from ScenePresence, it can lead to a race condition with the simulator loop.
There's no real point doing it anyway since the clear will be done very shortly afterwards by the simulate loop and either there are no events (for a new avatar) or events don't matter (for a departing avatar).
This matches existing behaviour in OdePrim
From sl docs such as http://community.secondlife.com/t5/English-Knowledge-Base/Managing-Private-Regions/ta-p/700115
agent should apply to avatars only.
This makes sense from a user perspective, and also from a code perspective since child agents with no physics or actions take up a fraction of root agent resources.
As such, the check is now only performed in Scene.QueryAccess() - cross and teleport check this before allowing an agent to translocate.
This also removes an off-by-one error that could occur in certain circumstances on teleport when a new child agent was double counted when a pre-teleport agent update was performed.
This does not affect an existing bug where limits or other QueryAccess() checks are not applied to avatars logging directly into a region.
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.
Will use one of three selected methods to route avatar landing
points when using Telehubs. The setting is in [Startup] using
SpawnPointRouting = closest/random/sequence
closest: The default setting. Routes avatar to the nearest SpawnPoint
to the location.
random: Picks random SpawnPoints to land the avatar.
sequence: Follows a sequence to place the avatar on the next available
SpawnPoint location

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
This does increase the aggressiveness of shutdown
Also prevents the bot list being locked for a long period, which was preventing commands such as "show bots" from working during shutdown
Still subject to change - if you use this be prepared to change your output code if/when the methods change.
Make new "attachments show" command use this.
completely rewritten every time a region starts up. This
makes the data write only when the data was not already
read from the database.
There is a still a major race condition whenever two regions
share the same estate data, but at least it won't be triggered
on startup.
This is usually because the file name was singular (*Service*) but the class name was plural (*Services*).
This is to make configuration easier rather than having to look in the c# code itself to find the slightly different name of the connector.
This does not affect existing configuration since the files are being renamed rather than the classes.
If AvatarService appearance data is retrieved over the network, then ServerUtils was attempting to transfer names such as "Wearable 0:0" directly to xml element names, resulting in an exception.
Space is not valid in xml element names. Neither is : in this case since the intention is not to namespace. Using names directly as keys is not a good idea.
To get around this problem this patch escapes and unescapes the element names as appropriate.
This has no impact on existing xml (since it had to be valid in the first place) but allows AvatarService data to be used over the network.
Setting appearance (from simulator to AvatarService) did not suffer this problem since the values are passed in the query string which is already properly escaped.
DuplicateObject() relies on source object having correct link numbers for the duration of the dupe.
Both link and delink can change link numbers such that they are not consistent for short periods of time.
This may be the wrong thing to do but stops lots of log spam in HG setups now that the monitoring is extended to other outgoing calls.
LongCallTime may need to be made configurable.
The functions DeleteFolders() and PurgeFolder() still work as before, i.e. they only allow deleting folders that are in the Trash. However, the functions DeleteFoldersEx() and PurgeFolderEx() can now be used to delete any folder.
This is because the viewer doesn't receive a timezone from the server but bases its displays on Pacific Standard Time.
However, it still expects to receive notification from the server as to whether or not Daylight Savings Time for PST is in operation.
This commit introduces a new DSTZone setting in the [LoginService] config setting that accepts a list of timezone names valid across different platforms to calculate Pacific DST.
If you need the old behaviour of calculating DST based on the local timezone of the server running the login service, then please override DSTZone with "local".
A mailing list announcement will be made later.
Thanks to Olivier Van Helden and Gudule Lapointe for determining this behaviour and providing this patch.
From http://opensimulator.org/mantis/view.php?id=5972
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 happened because the scripts were notified about control changes (e.g., the user stopped pressing the Forward key) when the animation was still WALK, so the script didn't stop the walking animation. Fixing this required: a) Update the movement animation *before* notifying the script; b) Add locking to prevent clashes with the Heartbeat thread (which also updates the animations); c) Handle the case of a user who stops walking just as the avatar is in the air: the avatar should STAND in that case, not WALK.
