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.
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.
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 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.
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 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.
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
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 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.
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.
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.
These are identical apart from setting Velocity = zero, which has no practical effect anyway since this is zeroed when the avatar is added back to the physics 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.
On region restart, the whole object would become physical as expected.
Observed behaviour from elsewhere is that all prims in a new linkset should take on the status of the root prim.
Add regression test for this behaviour.
prim_geom == IntPtr.Zero only before a new add prim taint is processed (which is the first taint) or in operations such as scale change which are done in taint or under lock.
Therefore, we can remove these checks which were not consistently applied anyway.
If there is a genuine problem, better to see it quickly in a NullReferenceException than hide the bug.
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.
We can now do this since the entire scene and all objects within it are now successfully gc'd at the end of these tests.
This greatly improves the time taken to run each test (by reducing teardown time, not the time to actually do the test work that we're interested in).
Slightly simplifies config read in Scene constructor to help facilitate this.
This is so that the static MainConsole.Instance doesn't retain references to methods registered by scene and other modules to service commands.
This prevents the scene from being garbage collected at the end of a test.
This is not the final thing preventing GC - next up is the timer started by SimStatsReporter that holds a reference to Scene that prevents end of test gc.
Permanently comment out warnings about ScenePresence not being found - this is entirely expected if the avatar has alraedy logged out or left the scene.
These behave identically to llAttachToAvatar() and llDetachFromAvatar() except that they do not enforce the PERMISSION_ATTACH check
Intended for use in completely controlled dedicated environments where these checks are more a UI hinderance than a help.
Threat level high.
However, at some point it would be far more convenient to receive the TaskInventoryItem in the constructor rather than just the item UUID, so we don't have to constantly refetch our self item.
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 was because update was looking for an existing stats record unique in session id, agent id and region id.
But if the user teleports to another region then region id changes.
WebStatsModule promptly doesn't find the existing record and tries to insert a new one, but only session id is the primary key and that's still the same, which makes things go bang.
This makes the update search only on the unique session id.
This is only an issue with simulators that have multiple regions where the webstats module is enabled.
