This is to avoid the entire scene loop being held up when the group service is slow to respond.
There's no obvious reason for these queries to be sync rather than async.
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.
This introduces a pull stat type in addition to the push stat type.
A pull stat takes a method on construction which knows how to update the stat on request.
In this way, special interfaces for pull stat collection are not necessary.
Even when an avatar is standing still, it's sending in a constant stream of AgentUpdate packets that the client creates new UDPPacketBuffer objects to handle.
This option pools those objects. This reduces memory churn.
Currently off by default. Works but the scope can be expanded.
This is controlled via the "debug lludp start <in|out|all>" and "debug lludp stop <in|out|all>" region console commands.
The command "debug lludp status" will show current status.
I think this is more useful right now since it tells us if the viewer requested a seed caps at all in various scenarios (such as when teleporting to a new region).
These were neither being returned or in many places reused.
Getting packets from a pool rather than deallocating and reallocating reduces memory churn which in turn reduces garbage collection time and frequency.
This allows different categories of stats to be shown, with options to list categories or show all stats.
Currently categories are scene and simulator and only a very few stats are currently registered via this mechanism.
This commit also adds percentage stats for packets and blocks reused from the packet pool.
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 is to resolve previous build break.
This unnecessarily but harmlessly reads and sets the parameter multiple times - scene was doing the same thing.
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 aims to capture the amount of memory that OpenSim turns over whilst operating a region.
This memory is not lost - apart from leaks it is reclaimed by the garbage collector.
However, the more memory that gets turned over the more work the GC has to do to reclaim it.
Giving a large folder from one avatar to another was causing a long delay when handled synchronously, since it took some time to retrieve the necessary data from the inventory service.
Handling this asynchronously instead stops this delay from disrupting all avatars in the scene. This has been shown in OSGrid.
I see no reason for not handling all IM messages asynchronously, just as incoming chat is handled asynchronously, so this has been switched for all instant messages.
Thanks to Nebadon for testing this change out.
This may well come back in the future when this subinterface is actually used but it currently isn't and I feel the name was poor.
Everything uses IClientAPI.RemoveEndPoint which also returned the full endpoint rather than just the ip address.
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.
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.
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).
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 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.
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.
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.
This lets us remove the dependency of OpenSim.Framework.dll on data/avataranimations.xml, which is not necessary for ROBUST.
This commit also takes care of the odd situation where animations are stored and used internally with uppercase names (e.g. "STAND")
but scripts refer to them with lowercase names (e.g. "sit").
Update() now accepts a frames parameter which can control the number of frames updated.
-1 will update until shutdown.
The watchdog updating moves above the maintc recalculation for any required sleep since it should be accounted for within the frame.
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.
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.
Setting PermissionMask.All will cause next permissions to replace current permissions when the object is rezzed, since bit 4 will be set.
This is not correct behaviour for a freshly uploaded mesh. Freshly rezzed in-world prims also do not have bit 4 set (don't yet know exactly what this is).
Should resolve http://opensimulator.org/mantis/view.php?id=5651
Telehub settings now persist to the database and are saved across sim restarts. So-far this only works on MySQL. this is a work in progress, teleport routing is not yet implemented.
Support for viewer side of telehub management. Can manupulate Telehubs and SpawnPoints from the viewer estate managemnt tools. This is a work in progress and does not yet persist or affect teleport routing.
Not yet enabled by default. You can enable this by setting Cap_FetchInventory2 = "localhost" in the [ClientStack.LindenCaps] section of OpenSim.ini
Enabling both FetchInventory2 and FetchInventoryDescendents2 improves the situation with properly fetching attachments and hud objects
Probably because viewers are never expecting the odd situation where FetchInventoryDescendents2 is present but not FetchInventory2
However, for some reason attachments and hud objects occasionally fail to appear, though their status is correct in inventory
For attachments, focussing on the avatar makes them appear. Hud objects have to be reattached.
As far as I know, viewers don't use this mechanism to recieve new TextureEntry data for avatars. This is done via the AvatarAppearance packet instead.
Tested this back to viewer 1.23.
Replacing with Utils.EmptyBytes since converting the texture entry to bytes on each AvatarUpdate (or which there are many) is not cost-free.
Further filters "debug packet <level>" to exclused [Request]ObjectPropertiesFamily if level is below 25.
Adjust some method doc
Minor changes to some logging messages.
The caller is already an async thread from LLClientView so this doesn't hold up the client.
However, launching on a separate thread does remove the effect of m_setAppearanceLock
This was potentially allowing two different SetAppearance threads to interfere with each other, though this probably rarely happens, if at all.
The only caller is the LLUDP stack and this has to validate the UDP circuit itself, so we know that it exists.
This allows us to eliminate another null check elsewhere and simplifies the method contract
This means that avatar/appearance data of other avatars and scene objects for a client will be sent after the ack rather than possibly before.
This may stop some avatars appearing grey on login.
This introduces a new OpenSim.Framework.ISceneAgent to accompany the existing OpenSim.Framework.ISceneObject and ISceneEntity
This allows IClientAPI to handle this as it can't reference OpenSim.Region.Framework.Interfaces
This meant that if a user exited the region, the UploadTexture handler would be effectively removed for everyone, causing subsequent failures.
This hopefully resolves the recent UploadTexture LLSD problems
This was a regression in 5640f2e (Thu Dec 1 23:24:15 2011 +0000)
This is required for the substitution of different HTTP servers or the newer HttpServer.dll without having to commit to a particular implementation.
This is also required to write regression tests that involve the HTTP layer.
If you need to recompile, all you need to do is replace OSHttpRequest/OSHttpResponse references with IOSHttpRequest/IOSHttpResponse.
Enabling this by setting Cap_FetchInventoryDescendents2 = "localhost" in the [ClientStack.LindenCaps] section of OpenSim.ini downloads inventory via http rather than udp in later viewers.
OutPacket() must be called within the m_killRecord lock. Otherwise the following event sequence is possible
1) LLClientView.ProcessEntityUpdates() passes the kill record check for a particular part suspends before OutPacket()
2) Another thread calls LLClientView.SendKillObject() to delete the same part and modifies the kill record
3) The same thread places the kill packet on the Task queue.
4) The earlier thread resumes and places the update packet on the Task queue after the kill packet.
This results in a ghost part in the sim that only goes away after client relog.
This commit also removes the unnecessary m_entityUpdates.SyncRoot locking in SendKillObject.
UpdateFlag is now referenced/used only within SOP and SOG. Outsiders are
using ScheduleFullUpdate, ScheduleTerseUpdate or ClearUpdateSchedule on
SOP consistently now. Also started working toward eliminating those
calls to ScheduleFullUpdate, ScheduleTerseUpdate or ClearUpdateSchedule
from outside SOP in favor of just setting properties on SOP and let SOP
decide if an update should be scheduled. This consolidates the update
policy within SOP and the client rather than everywhere that makes
changes to SOP. Some places forget to call update while others call it
multiple times, "just to be sure".
UpdateFlag and Schedule*Update will both be made private shortly.
UpdateFlag is intended to be transient and internal to SOP so it has
been removed from XML serializer for SOPs.
setting position at the same time as taint appears to undermine the whole purpose of taint
testing doesn't reveal any obvious regressions in doing this
This is necessary so that code in HttpServer can use framework facilities such as the thread watchdog for monitoring purposes.
Doing this shuffle meant that MainServer was moved into OpenSim/Framework/Servers
Also had to make OpenSim.Framework.Console rely on OpenSim.Framework rather than the other way around since it in turn relies on HttpServer
MainConsole and some new interfaces had to be moved into OpenSim/Framework to allow this. This can be reverted if parts of OpenSim.Framework stop relying on console presence (cheifly RegionInfo)
It's never possible for SOG to have no RootPart, except in the first few picosends of the big bang when it's pulled from region persistence or deserialized
The only times when ParentGroup might be null is during regression tests (which might not be a valid thing) and when scene objects are being constructed from the database.
At all other times it's not possible for a SOP not to have a SOG parent.
The root part state is the canonical value, so always send that instead.
Sending conflicting attachments states for non-root parts of a rezzed object is enough to crash the client.
Fixes http://opensimulator.org/mantis/view.php?id=5664.
Many thanks to mewtwo0641 for some fantastic qa work on this one.
This is done by introducing a PresenceType enum into ScenePresence which currently has two values, User and Npc.
This seems better than a SaveAttachments flag in terms of code comprehension, though I'm still slightly uneasy about introducing these semantics to core objects
this is to allow walking on prims. it will be up to the script writer to be sure that there is a continuous path.
currently implemented in osNpcMoveToTarget(), but none of this is final.
This now works again except that it requires a click or avatar mvmt to get going
This is because the ScenePresence.HandleAgentUpdate() method doesn't trigger until the client does something significant, at which point autopilot takes over.
Even clicking is enough to trigger.
This will be improved presently.
However, what happens now is that undo just doesn't do anything when the root prim is selected on its own. This requires more code than just fiddling with undo states.
This involves implementing a boolean in UndoState to signal whether the undo needs to be done for an entire group/linkset or just a single prim
Resizing individual components of linksets is still dodgy.
Resizing still has to be down twice, since for some reason the client is sending two multiobjectupdate packets on every resize except the very first. This applies to single prims and linksets. Need to look into this.
Undo rotation and position appear to be working.
Resizing a single prim appears to be working, though the undo has to be done twice.
Resizing a group of prims still does not work properly - possibly because in the UndoState we don't store a knowledge of when we're resizing a whole group rather than individual prims.
This needs to be addressed.
Unable to get to the bottom of why resizing a mesh fails to properly reset the physics proxy, when toggling phantom does
After a mesh is generated, the existing sculptdata is set to zero in PrimitiveBaseShape to save memory
When phantom is toggled, the sculptdata is regenerated before remeshing.
But on resize, the sculptdata is not regenerated.
So clearly, resetting sculptdata is possible, but haven't quite been able to pin down how this is being done when phantom is toggled.
Many thanks to the aurora project for pioneering this.
This code is almost certainly not bug free, but it does at least appear to handle simple meshes (except when the viewer crashes - but it is beta!).
Changed the experimental capability introduced a couple of commits ago: now sending that extra information as part of the response in the SimulatorFeatures cap.
It appears that if the viewer requests a folder containing links, we must also send the folders that contain the link targets first.
This was tested with Kokua 0.1.0 WIP though I predict it will also work with other viewer 2s

per Melanie's very good suggestion. The immediate queue is
serviced completely before all others, making it a very good
place to put avatar updates & attachments.

clients. If the sent packets are ack'ed successfully the throttle
will open quickly up to the maximum specified by the client and/or
the sims client throttle.
This still needs a lot of adjustment to get the rates correct.
Often, by the time the UDPServer realizes that an entity update packet
has not been acknowledged, there is a newer update for the same entity
already queued up or there is a higher priority update that should be
sent first. This patch eliminates 1:1 packet resends for unacked entity
update packets. Insteawd, unacked update packets are decomposed into the
original entity updates and those updates are placed back into the
priority queues based on their new priority but the original update
timestamp. This will generally place them at the head of the line to be
put back on the wire as a new outgoing packet but prevents the resend
queue from filling up with multiple stale updates for the same entity.
This new approach takes advantage of the UDP nature of the Linden protocol
in that the intent of a reliable update packet is that if it goes
unacknowledge, SOMETHING has to happen to get the update to the client.
We are simply making sure that we are resending current object state
rather than stale object state.
Additionally, this patch includes a generalized callback mechanism so
that any caller can specify their own method to call when a packet
expires without being acknowledged. We use this mechanism to requeue
update packets and otherwise use the UDPServer default method of just
putting expired packets in the resend queue.
this appears to cause problems with the system timer resolution.
This caused a problem with tokens going into the root throttle as
bursts leading to some starvation.
Also changed EnqueueOutgoing to always queue a packet if there
are already packets in the queue. Ensures consistent ordering
of packet sends.

Handling these synchronously kills the inbound packet loop if many requests are made for remote land and those requests are handled slowly or timeout (timeout is 10s)
This can happen if a user searches for "land for sale" and then clicks many of the parcels in the list (or just presses down arrow to move through every entry).
This applies to adding/removing estate users, groups, managers and bans.
