This is because they were wrongly looking for both regionid and region_id parameters in the same request.
Now only region_id is required (and recognized), regionid having been already deprecated for some time.
This is essentially Michelle Argus' patch from http://opensimulator.org/mantis/view.php?id=6737 but with tabs replaced with spaces.
Thanks!
Instead adjusts code with that from Packet.BuildHeader(byte[], ref int, ref int):Header in libomv
This stops packet decoding failures with agent UUIDs that contain 00 in their earlier parts (e.g. b0b0b0b0-0000-0000-0000-000000000211)
Thanks to lkalif for pointing this out.
This message is seen on V2 if one attempts to quickly re-teleport from a source region where one had previously teleported to a non-neighbour and back within 15 secs.
The solution here is for the user to wait a short while.
This message can also be seen on any teleport protocol if one recieves multiple teleport attempts simultaneously. Probably still useful here to help identify misbehaving scripts.
This approach has problems if a client quits without sending a proper logout but then reconnects before the connection is closed due to inactivity.
In this case, the DoNotCloseAfterTeleport was wrongly set.
The simplest approach is to close child agents on teleport as quickly as possible so that races are very unlikely to occur
Hence, this code now closes child agents as the first action after a sucessful teleport.
Normally, avatar motion is zeroed if colliding with a stationary object so
they don't slide down hills and such. Without volume detect check this also
allowed avatars to stand on volume detect objects and to have some jiggling
when they were in the volume detect object. This commit fixes both.

This fixes the problem of doing a teleport while the simulator is running.
The destruction of the physical object while the engine is running means
that the physics parameter update would overwrite the new position of the
newly created avatar.
Used to detect if a simulator is receiving significant junk UDP
Decimates the number of packets between which a warning is logged and prints the IP source of the last malformed packet when logging
IncomingCloseAgent() now sets the scene presence state machine properly, which is necessary to avoid races between multiple sources of close.
Hence, it's also necessary for everyone to consistently call IncomingCloseAgent()
Calling RemoveClient() directly is currently generating an attention-grabbing exception though this right now this is harmless.

is not with a volume detect object.
This fixes a problem of avatars trying to step over a volume detect object
that they collide with. This appeared as the avatar popping up as it started
to step up but then continuing on since the object wasn't physically interacting.
I think there is an argument for sending this information to NPCs anyway since in some cases it appears a lot easier to write server-side bots by hooking into such internal events.
However, would need to stop event messages building up on NPC queues if they are never retrieved.
This is giving much better results on teleports between simulators over my lan where for some reason there is a pause before the receiving simulator processes UpdateAgent()
At this point, v2 teleports between neighbour and non-neighbour regions on a single simulator and between v2 simulators and between a v1 and v2 simulator
are working okay for me in different scenarios (e.g. simple teleport, teleport back to original quickly and re-teleport, teleport back to neighbour and re-teleport. etc.)
This was occuring because teleport to B did not set DoNotCloseAfterTeleport on A as it was a neighbour (where it isn't set to avoid the issue where the source region doesn't send Close() to regions that are still neighbours (hence not resetting DoNotCloseAfterTeleport).
Fix here is to still set DoNotCloseAfterTeleport if scene presence is still registered as in transit from A
The root cause was that v2 was only closing neighbour agents if the root connection also needed a close.
However, fixing this requires the neighbour regions also detect when they should not close due to re-teleports re-establishing the child connection.
This involves restructuring the code to introduce a scene presence state machine that can serialize the different add and remove client calls that are now possible with the late close of the
This commit appears to fix these issues and improve teleport, but still has holes on at least quick reteleporting (and possibly occasionally on ordinary teleports).
Also, has not been completely tested yet in scenarios where regions are running on different simulators
This fixes the problem of avatars bouncing when logged in.
Added a little height to the avatar height fudges to eliminate a problem
of feet being in the ground a bit.

This stops OpenSimulator still trying to teleport the user if they hit cancel on the teleport screen or closed the viewer whilst the protocol was trying to create an agent on the remote region.
Ideally, the code may also attempt to tell the destination simulator that the agent should be removed (accounting for issues where the destination was not responding in the first place, etc.)
This can currently only be activated with the console command "debug stats record start".

This is for testing and debugging purposes to help determine whether a particular issue may be teleport related or not
"SIMULATION/0.2" (the newer teleport protocol) remains the default. If the source simulator only implements "SIMULATION/0.1" this will correctly allow fallback to the older protocol.
Specifying "SIMULATION/0.1" will force the older, less efficient protocol to always be used.

This is an experimental setting to control cpu spikes when an attachment heavy avatar logs in or avatars with medium attachments lgoin simultaneously.
It inserts a ms sleep specified in terms of attachments prims after each rez when an avatar logs in.
Default is 0 (no throttling).
"debug attachments <level>" changes to "debug attachments log <level>" which controls logging. A logging level of 1 will show the throttling performed if applicable.
Also adds "debug attachments status" command to show current throttle and debug logging levels.
What I believe is happening is that on initial terrain send, this is done one packet at a time.
With WaitOne, the outbound loop has enough time to loop and wait again after the first packet before the second, leading to a slower send.
This approach instead does not wait if a packet was just sent but instead loops again, which appears to lead to a quicker send without losing the cpu benefit of not continually looping when there is no outbound data.

Only HG Visitors get this var, to avoid spamming local users.
The config var is now called MapTileURL, to be consistent with the login one, and its being picked up from either [LoginService], [HGWorldMap] or [SimulatorFeatures], just because I have a bad memory.
This reflects the actual use of this stat - it hasn't recorded general exceptions for some time.
Make the sim extra stats collector draw the data from the stats manager rather than maintaing this data itself.
The major departure from flotsam is to send only one message per destination region, as opposed to one message per group member. This reduces messaging considerably in large groups that have clusters of members in certain regions.
This is a test setup failure since code paths when adding a duplicate root scene presence now require the EntityTransferModule to be present.
Test fixed by adding this module to test setup
These were genuine failures caused by ScenePresence.CompleteMovement() waiting for an UpdateAgent from NPC introduction that would never come.
Instead, we do not wait if the agent is an NPC.
- Child and root agents are only closed after 15 sec, maybe
- If the user comes back, they aren't closed, and everything is reused
- On the receiving side, clients and scene presences are reused if they already exist
- Caps are always recreated (this is where I spent most of my time!). It turns out that, because the agents carry the seeds around, the seed gets the same URL, except for the root agent coming back to a far away region, which gets a new seed (because we don't know what was its seed in the departing region, and we can't send it back to the client when the agent returns there).
This is because a returning viewer by teleport before 15 seconds are up will be disrupted by the close.
The 2 second delay is within the scope where a normal viewer would not allow a teleport back anyway.
Simulator/0.2 (V2) protocol will continue with the longer delay since this is actually the behaviour viewers get from the ll grid
and an early close causes other issues (avatar being sent to infinite locations temporarily, etc.)
This prevents an issue if the user teleports back to the neighbour simulator of a source before 15 seconds have elapsed.
This more closely emulates observed linden behaviour, though the timeout there is 50 secs and applies to all the pre-teleport agents.
Currently sticks a DoNotClose flag on ScenePresence though this may be temporary as possibly it could be incorporated into the ETM state machine
In this new protocol, and as committed before, the viewer is not sent EnableSimulator/EstablishChildCommunication for the destination. Instead, it is sent TeleportFinish directly. TeleportFinish, in turn, makes the viewer send a UserCircuitCode packet followed by CompleteMovementIntoRegion packet. These 2 packets tend to occur one after the other almost immediately to the point that when CMIR arrives the client is not even connected yet and that packet is ignored (there might have been some race conditions here before); then the viewer sends CMIR again within 5-8 secs. But the delay between them may be higher in busier regions, which may lead to race conditions.
This commit improves the process so there are are no race conditions at the destination. CompleteMovement (triggered by the viewer) waits until Update has been sent from the origin. Update, in turn, waits until there is a *root* scene presence -- so making sure CompleteMovement has run MakeRoot. In other words, there are two threadlets at the destination, one from the viewer and one from the origin region, waiting for each other to do the right thing. That makes it safe to close the agent at the origin upon return of the Update call without having to wait for callback, because we are absolutely sure that the viewer knows it is in th new region.
Note also that in the V1 protocol, the destination was getting UseCircuitCode from the viewer twice -- once on EstablishAgentCommunication and then again on TeleportFinish. The second UCC was being ignored, but it shows how we were not following the expected steps...
If this consistently increases then this is a problem since it means the simulator is receiving more requests than it can distribute to other parts of the code.
If we're not receiving packets with multiple threads (m_asyncPacketHandling) then this is critical since it will limit the number of incoming UDP requests that the region can handle and affects packet loss.
If m_asyncPacketHandling then this is less critical though a long process will increase the scope for threads to race.
This is an experimental stat which may be changed.

- The existing event to scene has been split into 2: OnAgentUpdate and OnAgentCameraUpdate, to better reflect the two types of updates that the viewer sends. We can run one without the other, which is what happens when the avie is still but the user is camming around
- Added thresholds (as opposed to equality) to determine whether the update is significant or not. I thin these thresholds are ok, but we can play with them later
- Ignore updates of HeadRotation, which were problematic and aren't being used up stream
