Add 'not found' caching in EntityTransferModule.GetRegionContainingWorldLocation
so hitting borders and bad teleports do not continuiously hammer on the GridService.
Add new region crossing code to varregion
Conflicts:

Rename 'RegionWorldLocX' to 'WorldLocX' and same for Y and Z.
This keeps the downward compatibility and follows the scheme of 'region'
and 'world' location naming that is happening in the Util module.
- Parts of region crossing code
- New bakes handling code
- Bakes now sent from sim to sim without central storage
- Appearance handling changes
- Some changes to sitting
- A number of unrelated fixes and improvements
Routines in Util to compute region world coordinates from region coordinates
as well as the conversion to and from region handles. These routines have
replaced a lot of math scattered throughout the simulator.
Should be no functional changes.
handle variable sized regions. Many changes for both the region and parcels.
Most of the constant "4" (for the 4x4 parcel units) have been replaced
with symbols and math.
* Applied the XmlRpcBasicDOSProtector.cs to the login service as both an example, and good practice.
* Applied the BaseStreamHandlerBasicDOSProtector.cs to the friends service as an example of the DOS Protector on StreamHandlers
* Added CircularBuffer, used for CPU and Memory friendly rate monitoring.
* DosProtector has 2 states, 1. Just Check for blocked users and check general velocity, 2. Track velocity per user, It only jumps to 2 if it's getting a lot of requests, and state 1 is about as resource friendly as if it wasn't even there.
-- addition of varaible region size in X and Y
-- internal storage of heightmap changed from double[] to short[]
-- helper routines for handling internal structure while keeping existing API
-- to and from XML that adds region size information (for downward compatibility,
output in the legacy XML format if X and Y are 256)
Updated and commented Constants.RegionSize but didn't change the name for compatibility.
count number to integer world coordinates.
Added new methods RegionWorldLoc[XY].
Refactored name of 'RegionLoc*' to 'LegacyRegionLoc*' throughout OpenSim.
Kept old 'RegionLoc*' entrypoint to RegionInfo for downward compatability
of external region management packages.
When a user gives an item, the user's client sends an InventoryOffered IM message to its simulator. This adds the item to the receiver's inventory. If the receiver isn't in the same simulator then XMLRPC is used to forward the IM to the correct simulator. The bug was that the receiving simulator handled the message by calling OnInstantMessage() again, which added a second copy of the item to the inventory. Instead, the receiving simulator should only notify the avatar that the item was offered.
This is specified in the MaxOutgoingTransferVersion attribute of [EntityTransfer] in OpenSim.ini, see OpenSimDefaults.ini for more details.
Default remains "SIMULATION/0.2"
Primarily for http://opensimulator.org/mantis/view.php?id=6755
Leaves in the dropping of the client GUN8 (now 9) uuid binding message, since this was the much more common case from the viewer-side and this can only affect viewers.
By not binding UUID -> "Unknown User", we leave open the possibility that the binding may be correctly resolved at a later time, which can still happen in some Hypergrid situations.
Observed behaviour of LL viewer 3.3.4 is that a dropped bind request is not retried until the next session.
This occurs on v2 teleport since the source region now waits 15 secs before closing the old child agent, which could still receive chat.
This commit introduces a ScenePresenceState.PreClose which is set before the wait, so that ChatModule can check for ScenePresenceState.Running.
This was theoretically also an issue on v1 teleport but since the pause before close was only 2 secs there, it was not noticed.
This requires a new GridService.GetDefaultHypergridRegions() so ROBUST services require updating but not simulators.
This method still returns regions flagged with just DefaultRegion after any DefaultHGRegions, so if no DefaultHGRegions are specified
then existing configured defaults will still work.
Immediate use is for conference where we need to be able to specify different defaults
However, this is also generally useful to send experienced HG users to one default location and local users whose specified region fails (e.g. no "home" or "last") to another.
This exception was very likely harmless since it occurred after the restart had taken place, but still misleading.
Thanks to SCGreyWolf for the code change suggestion in http://opensimulator.org/mantis/view.php?id=6747, though I did this in a slightly different way.
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.
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
For unknown reasons, a dynamic function signature cannot have more than 5
parameters. Error message now tells you this fact so you can curse MS and
then go change your function definitions.
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 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.
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.
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.
- 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...
This adds explicit cap poll handler supporting to the Caps classes rather than relying on callers to do the complicated coding.
Other refactoring was required to get logic into the right places to support this.
Revert "Trying to reduce CPU usage on logins and TPs: trying radical elimination of all FireAndForgets throughout CompleteMovement. There were 4."
This reverts commit 6825377380.
This was a regression since commit 831e4c3 (Thu Apr 4 00:36:15 2013)
This commit also adds a regression test for this case, though this currently only works with Mono
This aims to address http://opensimulator.org/mantis/view.php?id=6704
This currently prints caps requests received and handled, so that overload of received compared to handled or deadlock can be detected.
This involves making BaseStreamHandler and BaseOutputStream record the ints, which means inheritors should subclass ProcessRequest() instead of Handle()
However, existing inheriting classes overriding Handle() will still work, albeit without stats recording.
"show caps" becomes "show caps list" to disambiguate between show caps commands
Unknown UserUMMAU3 insertion should definitely be removed down the line.
However, I would like a little more time to check the GUN* reduction first, since removing UMMAU3 will make these failures appear as GUN7 instead.
Also bumps GUN6 -> GUN7 and UMMAU2 -> UMMAU3
This is to see the impact that Diva's fixes related to this issue (last one is currently commit c7383688)
You will need to clear your viewer cache for this to have any effect

This is in order to reduce the likelihood of naming clashes, make it easier to filter in/out attributes, ensure uniformity, etc.
All dynattrs in the opensim distro itself or likely future ones should be in the "OpenSim" namespace.
This does alter the underlying dynattrs data structure. All data in previous structures may not be available, though old structures should not cause errors.
This is done without notice since this feature has been explicitly labelled as experimental, subject to change and has not been in a release.
However, existing materials data is being preserved by moving it to the "Materials" store in the "OpenSim" namespace.
This string is returned if a UserManagementModule.TryGetUserNames() cannot find a server-side name binding or a user account for a given UUID.
This is only called when the viewer requests a binding via the UDP UUIDNameRequest message
This patch changes the land show console command to return numbers in the
range 4 to 256 for the "to" coordinates instead of 0 to 252
Also trailing spaces removed from some lines.
differentiates between local & grid storage. The Temporary property just
says that which service handles the it, the asset can be safely removed
in the future.
The UMMTGUN form of Unknown User seems to appear because a viewer sometimes sends a UUIDNameRequest UDP request that fails to find a binding.
However, in theory the incoming agent should have made that binding before any such request is triggered.
So moving this binding to an earlier point in the process to see if this makes a difference.
Unknown user name is also updated to UserUMMTGUN2 - if you see the old name then you need to clear your viewer cache.

hashes for the purpose of accurately responding to AgentTextureCached
packets. There is a change to IClientAPI to report the wearbles hashes
that come in through the SetAppearance packet. Added storage of the
texture hashes in the appearance. While these are added to the
Pack/Unpack (with support for missing values) routines (which means
Simian will store them properly), they are not currently persisted in
Robust.
Without explicit config non-hg UMM is used - this is in common with other HG modules.
This was causing a non-HG module to unpredictably use the UMM or HGUMM, though lack of bug reports suggest either UMM was always used or it didn't matter in this case.
This is controlled by the viewer, not the server.
So as per http://wiki.secondlife.com/wiki/LlSetSoundQueueing, only two sounds can be queued per prim.
You probably need to use llPreloadSound() for best results

This is so that other callers (such as SceneCommunicationService.SendCloseChildAgentConnections() can perform all closes asynchronously without pointlessly firing another thread for local closes).
No functional change apart from elimination of unnecessary chaining of new threads.
This was because this particular code path (unlike user delete) only sent kills to root presences, for no apparent good reason.
Added regression test for this case.
This fixes http://opensimulator.org/mantis/view.php?id=6627
packet can be pulled out of LLClientView and moved to
AvatarFactory. The first pass at reusing textures (turned off by
default) is included. When reusing textures, if the baked textures
from a previous login are still in the asset service (which generally
means that they are in the simulator's cache) then the avatar will not
need to rebake. This is both a performance improvement (specifically
that an avatars baked textures do not need to be sent to other users
who have the old textures cached) and a resource improvement (don't
have to deal with duplicate bakes in the asset service cache).
Fix issue where objects rezzed from Trash or Lost And Found then be placed back in the respective folder when taking the object or a copy back into inventory.
The previous wrong behavior caused the debug setting "UseHTTPInventory" to fail
on all viewers when turned off. UDB inventory would not be correctly used in
that case.
This fixes the combined bounding box location for regions bigger than 256x256.
It also fixes the position on taking coalesced objects in the non-root regions, where position checks are properly done on rez instead.
It also fixes the megaregion land channel to return null if the land does not exist, which should probably also be done for the ordinary land channels rather than returning a dummy region.
Inspiration from Garmin's commit in http://opensimulator.org/mantis/view.php?id=6595. Thanks!
This was because AsyncCommandManager was handing an item ID to IHttpRequestModule.StopHttpRequest() rather than the expected request ID.
This commit also makes the http request asynchronous using BeginGetResponse() rather than doing this by launching a new thread
so that we can more safely abort it via HttpWebRequest.Abort() rather than aborting the thread itself.
This also renames StopHttpRequest() to StopHttpRequestsForScript() since any outstanding requests are now aborted and/or removed.
By checking against the grid's Avatar data, we can ignore viewer side attachments but still initiate these calls simulator-side.
Initiating simulator-side is always necessary for version 1 viewers.
This is a further commit to resolve http://opensimulator.org/mantis/view.php?id=6581
This was because the script resumption in AttachmentsModule was firing the attach event instead.
Had to reinstate the code in 285bd3a do we can resume the scripts there instead, though the bug existed before its removal.

Unfortunately fails on Nebadon's system right now. Needs investigation. May put in a temproary option for experimentation soon.
This reverts commit d87ddf50fc.
On my own system, I can now eliminate the pause entirely and the reteleport happens whilst the teleport screen is still up.
Trying this change to see if this is true for other people.
This is a further effort to reduce v3 viewer race conditions where this call may clash with the viewer signalling attachment wearing from its current outfit folder.
This is to simplify the code (no tricky 'wasChild' signalling required)
and to reduce the risk of a thread clash between simulator-side attaching (necessary for v1 viewers)
and the viewer-side attaching the v3 viewers perform.
This looks like an off-by-one bug since the view distance was already only 256 on the west and south sides.
This reduces the number of child agents being logged into regions neighbouring a megaregion.
