In testing, it appears that if multiple threads dispose of separate GDI+ objects simultaneously,
the native malloc heap can become corrupted, possibly due to a double free(). This may be due to
bugs in the underlying libcairo used by mono's libgdiplus.dll on Linux/OSX. These problems were
seen with both libcario 1.10.2-6.1ubuntu3 and 1.8.10-2ubuntu1. They go away if disposal is perfomed
under lock.
If a group UUID is present that is not on this simulator then the object or parcel is no longer group owned.
This is a change from previous behaviour where such invalid UUIDs were kept.
This is an adaptation of patch 0002 from http://opensimulator.org/mantis/view.php?id=6105 by Oren Hurvitz of Kitely.
My adaptations are formatting only, apart from the notices about parcel owner IDs not being saved since this has now been fixed.
Thanks Oren.
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 was working in 0.7.2 but was accidentally removed from 0.7.3.
The --publish option for "save oar" will now save oars stripped of parcel owner information as well as scene object info.
Please use the --publish option if you want to publish oars that may be later loaded by others to the same grid from which they were saved.
The bug manifested as follows: a large world was saved. All the assets were found. But for some unknown reason, the timeout timer was restarted. So after 1 minute it closed the Archive Writer, because it didn't receive any more assets during that minute. That caused the OAR to become corrupted because ArchiveWriteRequestExecution.Save() was still running.
The convention is that if an object implements IDiposable() the code must explicitly call Dispose() or call it via the using statement.
This may be particularly important for GDI+ objects since they encapsulate native code entities.
If we copy the asset description then we will only ever replicate the very first description, if there was one, not any subsequent changes.
Thanks to Oren Hurvitz of Kitely for this patch from http://opensimulator.org/mantis/view.php?id=6107
I have adapted it slightly to change the order of arguments (name before description rather than vice-versa) and slightly improve some method doc.
This is fired when all regions are ready or when at least one region becomes not ready.
Recently added EventManager.OnRegionReady becomes OnRegionReadyStatusChange to match OnLoginsEnabledStatusChange
justincc's original work. Sample scripts before doing so. Also refactor some
crucial common code and eliminate parameters that were only ever used with
the same constant value.
This replaces EventManager.OnLoginsEnabled which only fired when logins were first enabled
and was affected by a bug where it would never fire if the region started with logins disabled.
This saves listeners from having to re-retrieve the scene from their own lists, which won't work anyway if multiple regions with the same name have been allowed
This appears to be a regression from back in commit db91044 (Mon Aug 22 2011) where we started to send TaskInventoryOffered msg dialog rather than InventoryOffered dialog.
This is probably correct, but failed because the bucket was too large and because we wouldn't have handled the TaskInventoryDeclined option anyway.
This patch handles both of these and make llGiveInventoryList() use TaskInventoryOffered as well
Fixes http://opensimulator.org/mantis/view.php?id=6089
Note, this behaviour appears to be at variance with the ll grid as of Tues 17 July 2012, testing with viewer 3.2.1.
The item name in inventory does not change either at the point of detach or after a relog.
This doesn't seem to make any sense and probably stems from a period when this code was directly involved in attaching objects directly from the scene.
This message is already being sent by InventoryAccessModule code instead.
The encodings are thread-safe and already used in such a manner in other places.
This isn't done where Byte Order Mark output is suppressed, since Encoding.UTF8 is constructed to output the BOM.
This is only currently meant for use by regression tests that don't have any issues if XEngine is started up quickly, since no other operations will be occuring simultaneously.
Therefore, this is not yet documented externally.
This is to fix a regression starting from 5301648 where attachments had to start being deleted before persistence in order to avoid race conditions with hud update threads.
This prevents a stack overflow where a get position on the avatar will refer to the attachment which will in turn refer back to the avatar.
This required recording of all sitting avatars on a prim which is done separately from recording the sit target avatar.
Recording HashSet is null if there are no sitting avatars in order to save memory.
This was causing 2 copies of the module to be created for each scene.
Probably no bad consequences other than a small waste of memory (both for the module and for the warp3D renderer it loaded)
This works like osForceAttachToAvatar() but allows an object to be directly specified from the script object's inventory rather than forcing it to be rezzed in the scene first.
Still only attaches objects to the owner of the script.
This allows one to bypass the complicated co-ordination of first rezzing objects in the scene before attaching them.
Threat level high.
null would only ever be returned if the item couldn't be located within inventory and this would happen immediately.
In this case, derezzing wouldn't work anyway since there is no item to derez.
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.
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)
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)
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.
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.
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 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 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.
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
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.
Addresses http://opensimulator.org/mantis/view.php?id=5948, http://opensimulator.org/mantis/view.php?id=5749
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 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
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 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.
Permanently comment out warnings about ScenePresence not being found - this is entirely expected if the avatar has alraedy logged out or left the 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.
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 makes it consistent with other parts of OpenSimulator that are treating ESTATE_MANAGER and ESTATE_OWNER as different entities.
As per opensim-dev mailing list.
Use existing cache if the avatar is within the region and use an
ExpiringCache to cache status if the avatar is not in the region. The
30 second delay now applies to scripted objects ony and only when the owner
is not present.
Another thread could come and turn off physics for a part (null PhysicsActor) at any point.
Had to turn off localCopy on warp3D CoreModules section in prebuild.xml since on current nant this copies all DLLs in bin/ which can be a very large number with compiled DLLs
No obvious reason for doing that copy - nothing else does it.
Rename IFriendsModule.GetFriendPerms() -> GetRightsGrantedByFriend() to be more self-documenting and consistent with friends module terminology.
Add some method doc.
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.
Unfortunately, the OnLoginsEnabled event is currently only guaranteed to fire if the RegionReady module is active.
However, we can instantiate the AuthorizationService in the module RegionLoaded method since by this time all other modules will have been loaded
The previous lines-per-second measurement used for top scripts report was inaccurate, since lines executed does not reflect time taken to execute.
Also, every fetch of the report would reset all the numbers limiting its usefulness and we weren't even guaranteed to see the top 100.
The actual measurement value should be script execution time per frame but XEngine does not work this way.
Therefore, we use actual script execution time scaled by the measurement period and an idealised frame time.
This is still not ideal but gives reasonable results and allows scripts to be compared.
This commit moves script execution time calculations from SceneGraph into IScriptModule implementations.

- Added an inventory cache for caching root and system folders
- Synchronized the remote inventory connector, so that all the remote inventory calls are serialized
This will not make much difference in the hold ups. We'd have to move the FireAndForget high up to AddInventoryItem, but that opens up a can of worms regarding the notification of the recipient... the recipient would be notified of the offer before the items are effectively in his inventory, which could lead to surprises.
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.
I believe this was originally required back when there could be two LocalGridServiceConnectors but this is no longer the case.
Having such statics makes performance testing much more difficult since they prevent GC of objects unless static references are explicitly nulled.
This is the start of exploring the creation of a bundled OpenSimulator asset service that does de-duplication and possibly file storage of assets.
Along the lines of coyled's SRAS, but not intended to replace, merely to act as a more performant bundled default.
Might end up nicking stuff from kcozen's patch at http://opensimulator.org/mantis/view.php?id=5429
More details at http://opensimulator.org/wiki/Feature_Proposals/Deduplicating_Asset_Service
Feedback and discussion welcome as commits are made.
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.
This involves
1) On forcible teleport, call m_scene.RequestTeleportLocation() rather than ScenePresence.Teleport() - only EntityTransferModule now should call SP.Teleport()
2) When avatar is being forcibly moved due to banlines, use a 'stop movement' tolerance of 0.2 to requested position rather than 1
This prevents the avatar sometimes being stuck to banlines until they teleport somewhere else.
This aims to fix some problems in http://opensimulator.org/mantis/view.php?id=5822
potential bad update that places an object at the opposite side of the
origin sim for a moment before actually crossing it. Especially important in
grids like OSG where lag between sims is high.
This fixes the problem by fixing the permissions module to look at root part permissions rather than having to do this for every caller.
Resolves http://opensimulator.org/mantis/view.php?id=5569
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
These commands will display part/prim details for a given uuid or name
The "show object uuid" and "show object name" commands will now only display details for objects (i.e. not child parts in a linkset).
This is for consistency with the "delete object" commands which only delete objects, not parts.
I had code made additions to the map module that was based on the earlier work that I did before Melanie made improvements. Updating the new code to incorporate the same changes.
This is damage control es EstateSettings is not the place this can be put.
EstateSettings is nt unique to a region and therefore would introduce
a hard limit of one telehub per estate, completely shutting off the
option of having SL style telehubs, e.g. one per region. Whole
estate teleport routing can still be implemented id desiresd, this
way all options are open while the other way most options get closed
off.
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.
Doing this in every script is unnecessary since the event trigger is parameterized by the item id.
All that would happen is 2000 scripts would trigger 1999 unnecessary calls, and a large number of initialized scripts may eventually trigger a StackOverflowException.
Registration moved to UrlModule so that the handler is registered for all script engine implementations.
This required moving the OnScriptRemoved and OnObjectRemoved events (only used by UrlModule in core) from IScriptEngine to IScriptModule to avoid circular references.
loading an archive. This does add an extra roundtrip to the asset
server if loading new assets but it protects against overwriting
(and potentially corrupting) existing assets.
This is not as useful as it sounds, since you can only request rebakes for texture IDs already received.
In other words, if the viewer has never sent the server this information (which happens quite often) then it will have no effect.
Nonetheless, this is useful for diagnostic/debugging purposes.
Update basic profile to use the replaceable interface, making configuration less error-prone. Add support to query avatar's home user account and profile service for regions usng the updated OpenProfileModule with Hypergrid.
into a region that does not exist. This is particularly problematic for
physical objects where the velocity continues to move them out of the
region causing an infinite number of failed region crossings. The patch
forces an object that fails a crossing to be non-physical and moves it
back into the starting region.
Further filters "debug packet <level>" to exclused [Request]ObjectPropertiesFamily if level is below 25.
Adjust some method doc
Minor changes to some logging messages.
There were two problems here:
1) On object group update, we looked for the group is the IClientAPI group cache rather than in the groups service. This fails to groups created newly in that session
2) On object group update, we weren't setting the HasGroupChanged flag. This meant that the change was not persisted unless some other action set this flag.
This commit fixes these issues and hopefully addresses http://opensimulator.org/mantis/view.php?id=5588
This commit also moves HandleObjectGroupUpdate() to the GroupsModule from the Scene.PacketHandlers.cs file
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.
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.
This required an option to be added to NullRegionData via ConnectionString for it to act as a non-static instance, so that regression tests (which only load this class once) don't get hopeless confused and complex to compensate.
Normal standalone operation unaffected.
This is misleading since a simulator will call this method before successfully trying remote regions.
Also comments out spammy "[SIMULATION]: Stream handler called" AgentHandlers messages for now.
This might help with
[USER AGENT CONNECTOR]: new connector to ()
[USER AGENT CONNECTOR]: Unable to contact remote server for GetServerURLs
[USER AGENT CONNECTOR]: Malformed Uri : Argument cannot be null.
Parameter name: uriString
Executing this asynchronously allows a race condition where subsequent friends fetches hit a cache that FetchFriendsList() had not yet populated.
Changing this to synchronous may improve issues where a user does not see friends as online even though they are.
I don't believe synchronous is a problem here, but if it is, then a more complicated signalling mechanism is required. Locking the cache isn't sufficient.
from previous commit which sort out which iterator is used are left
intact. A discussion is needed as to what constitutes an avatar vs a
ScenePresence.
the 3 iteration functions so more of them are using the correct
iteration for the action they are performing. The 3 iterators that seem
to fit all actions within OpenSim at this time are:
ForEachAvatar: Perform an action on all avatars (root presences)
ForEachClient: Perform an action on all clients (root or child clients)
ForEachRootClient: Perform an action on all clients that have an avatar
There are still a dozen places or so calling the old
ForEachScenePresence that will take a little more refactoring to
eliminate.
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.
In AvatarFactoryModule.HandleAppearanceUpdateTimer(), we loop through appearance save and send requests and dispatch via a FireAndForget thread.
If there was more than one request in the save or send queue, then this led to a subtle race condition where the foreach loop would load in the next KeyValuePair before the thread was dispatched.
This gave the thread the wrong avatar ID, leaving some avatar appearance cloudy since appearance data was never sent.
This change loads the fields into local references so that this doesn't happen.
This should be unecessary since the folder update is already made at the time of the offer (and moved to trash if not accepted).
This code was also not taking into account the situation where an item was accepted.
Needs more fixing if this results in an aggression elsewhere.
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)
These are disabled by default, as before. Please only turn these on in secure grids, since they allow the same facilities as the existing SetPassword call (also disabled by default)
These facilities can be helpful when integrating external systems, in addition to the existing option of adapting an IAuthenticationService or using WebLoginKey
Unlike the other 3 stats mechanisms, monitor data can be queried per individual region, which makes this useful.
This doesn't affect an of the existing monitored stats.
ways to access the list/dictionary of child regions and locking was
inconsistent. There are now public properties which enforce locks.
Callers are no longer required to create new copies of lists.
Original request URLs that end with / will still work, but this will allow one to type /simstatus as well as /simstatus/
Can't do this with webstats yet since it does insane things to the path.
I added the boolean config setting "allow_regionless", defaulting to false. If set to true, opensim will start up ok if no region configurations are found in the specified region_info_source. It will not ask the user to create a region.
If a user account isn't available, this just passes on the name given by the agent instead.
I'm not sure this is particularly useful since I believe that agent names could be faked in this context - it might be no more useful than a viewer agent string.
In fact, there might even be an argument that passing on this name provides a false expectation of authenticity. However, I will apply for now.
Patch applied from http://opensimulator.org/mantis/view.php?id=5696
Thanks Michelle Argus.
When a slider parameter is changed, the viewer uploads a new shape (or other asset) and the item is updated to point to it.
Viewer 1 uploaded the data in the initial request itself, so the asset references was almost always correctly updated.
However, viewer 3/2 always uploads data in a subsequent xfer, which exposed a race condition where the viewer would make the item update before the asset had uploaded.
This commit shuffles the order of operations to avoid this race, the item is updated with the new asset id instead of the old one while the upload was still taking place.
A second race had to be fixed where avatar appearance would also be updated with the old asset id rather than the new one.
This was fixed by updating the avatar appearance ids when the appearance was actually saved, rather than when the wearables update was made.
It turns out that the HG lure module was setting up a pending lure when it intercepted the instant message on its way out to the target avatar.
However, an IM would only be sent if the user was remote, so it would not be set up for users on the same sim or in an immediate neighbour.
We fix this by adding the pending lure when the message goes out and ignoring a duplicate pending lure add if it goes to out via IM.
Hopefully addresses http://opensimulator.org/mantis/view.php?id=5690
Viewer 2 no longer contains the default avatar assets (i.e. "Ruth") that would appear if the user had insufficient body part/clothing entries.
Instead, avatars always appear as a cloud, which is a very bad experience for out-of-the-box OpenSim.
Default is currently off. My intention is to switch it on for standalone shortly.
This is not particularly flexible as "Ruth" is hardcoded, but this can change in the future, in co-ordination with the existing RemoteAdmin capabilities.
Need to fix creation of suitable entries for users created as estate owners on standalone.
Avatars still appear with spooky empty eyes, need to see if we can address this.
This commit adds a "Default Iris" to the library (thanks to Eirynne Sieyes from http://opensimulator.org/mantis/view.php?id=1461) which can be used.
Viewer 2/3 will sometimes attempt to rewear attachments, even though they have already been attached during the main login process.
This change ignores those attempts.
This stops script failures during login, as the rewearing was racing with the script startup code.
It might also help with attachments being abnormally put into deleted state.
Hopefully resolves some more of http://opensimulator.org/mantis/view.php?id=5644
As far as I can see, this is only invoked by a PUT request to ObjectHandlers, which is not being used anyway.
Invoking attachments code at this point is probably inappropriate since it would still be invoked when the client entered the scene.
Being commented to simplify analysis of attachments issues. Can be uncommented when in use.
Also, small tweak to lock and log removal of a SOG from the SceneObjectGroupsByLocalPartID collection in SceneGraph.GetGroupByPrim() if an inconsistency is found.
Attach and detach packets are processed asynchronously when received from a viewer.
Bugs like http://opensimulator.org/mantis/view.php?id=5644 indicate that in some situations (such as attaching/detaching entire folders of objects at once), there are race conditions between these threads.
Since multiple data structures need to be updated on attach/detach, it's not enough to lock the individual collections.
Therefore, this commit introduces a new IScenePresence.AttachmentsSyncLock which add/remove operations lock on.
Leaving them at UUID.Zero meant that when a viewer 2 logged into a region that had been freshly created, it received UUID.Zero for these textures, and hence display the land as plain white.
On a simulator restart, the problem would go away since when the database adapators loaded the new region settings, RegionSettings itself has code to use default textures instead of UUID.Zero.
This commit resolves the problem by saving the default texture UUIDs instead of Zero.
However, we currently have to do this in a roundabout way by resaving once the RegionSettings have been created by the database for the first time. This needless complexity should be addressed.
This change will also have the effect of replacing any existing UUID.Zero terrain textures with the default ones.
However, this shouldn't have any effect since the UUID.Zeros were already being replaced in memory with those same UUIDs.
This is to address http://opensimulator.org/mantis/view.php?id=5669
However, if this failure was happening I'm kind of surprised that local HG inventory was working at all.....
We probably weren't seeing these exceptions previously because we weren't logging them when the reached the top of a FireAndForget thread.
This is for http://opensimulator.org/mantis/view.php?id=5669
If we can't retrieve an IUserManagement module we complain, and we also warn in the log when its manually set in XISC by HGInventoryBroker
When a user logs in, the attachment item ids are pulled from persistence in the Avatars table. However,
the asset ids are not saved. When the avatar enters a simulator the attachments are set again. If
we simply perform an item check then the asset ids (which are now present) are never set, and NPC attachments
later fail unless the attachment is detached and reattached.
Hopefully resolves part of http://opensimulator.org/mantis/view.php?id=5653
The code in question is over three years old and just be catching an inconsistency rather than being wholly necessary.
This commit still carries out the check and prints all the previous log warnings but a 'failure' no longer prevents avatar region crossing or teleport, and it doesn't give the client the error message.
This will have some kind of impact on http://opensimulator.org/mantis/view.php?id=5672
Not doing this causes NREs whenever that user tries to access inventory when Hypergrid is turned on since the Remote connector does not have a scene (which is only used to fetch the UserManager)
Aims to address http://opensimulator.org/mantis/view.php?id=5669
This was happening because we were using the source avatar's item IDs in the clone appearance.
Switch to using the asset IDs of attachments instead for NPCs.
The InventoryAccessModule and AttachmentModule had to be changed to allow rezzing of an object without an associated inventory item.
Hopefully goes some way towards resolving http://opensimulator.org/mantis/view.php?id=5653
This method wasn't actually doing anything since dropped attachments retain a PCode of 9.
Also, behaviour of dropped attachments in other places appears to be that they persist after avatar logout rather than get deleted.
Even though we don't use these on rez they are still present after an unlink, after which selecting them causes various viewers to crash
Hopefully really does address http://opensimulator.org/mantis/view.php?id=5664
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 approach here, as in other parts of OpenSim, is to return a copy of the list rather than the attachments list itself
This prevents callers from forgetting to lock the list when they read it, as was happening in various parts of the codebase.
It also improves liveness.
This might improve attachment anomolies when performing region crossings.
Apart from one obvious bug, this was failing because attempting to serialize the script from inside the script (as part of saving the attachment as an inventory asset) was triggering an extremely long delay.
So we now don't do this. The state will be serialized anyway when the avatar normally logs out.
The worst that can happen is that if the client/server crashes, the attachment scripts start without previous state.
llRegionSay will now message avatars on chan 0
and will message attachments on the avatar that
listen on channels other than 0.
This behavior is consistant with the LL
implementation as tested on regions in Agni
with one exception: this implementation does
not include issue:
https://jira.secondlife.com/browse/SCR-66?
This meant punching in another AddUser() method in IUserManagement to do a direct name to UUID associated without the account check (since NPCs don't have accounts).
May address http://opensimulator.org/mantis/view.php?id=5645
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 executes the callback on the same thread that made the request. Designed for use only by regression tests that rely on a predicable event ordering.
Copying doesn't prevent IOExceptions on Windows due to file locking. (e.g. Mantis 5642, 5630).
So instead go back to moving the file, swallowing IOExceptions that occur just for the move due to competing caching threads or even different opensimulator instances.
This hopefully addresses http://opensimulator.org/mantis/view.php?id=5634
This is the most probable cause of the memory problems that people have been seeing in the past month.
This bug has been around since commit 5dc785b (4th July 2011). Doh! This is why regressions tests are such a good idea... :)
Many thanks to Nebadon for using git bisect to track down this bug, which made it a 5 minute fix.
This works by serializing and deserializing NPC AvatarAppearance to a notecard in the prim inventory and making the required baked textures permanent.
By using notecards, we avoid lots of awkward, technical and user-unfriendly issues concerning retaining asset references and creating a new asset type.
Notecards also allow different appearances to be swapped and manipulated easily.
This also allows stored NPC appearances to work transparently with OARs/IARs since the UUID scan will pick up and store the necessary references from the notecard text.
This works in my basic test but is not at all ready for user use or bug reporting yet.
Avatar moves and stops. However, will stop in mid stride.
And if the move to position is in the air, avatar will continue to make vain and quite hilarious attempts to take off (but never doing so).
Clearly more work is needed.
Had to stop using AvatarService for now since it doesn't store baked texture IDs (which is why this was failing).
Also failing because cloning appearance was also cloning the AvatarApperance.Owner field, which we weren't then changing.
Extended TestCreate() to check this.
This is to accomodate situations where the authorization service is being used by the hypergrid, where visitors have no user account.
See http://opensimulator.org/mantis/view.php?id=5517, this code is somewhat adapted/cleaned up from Michelle's patch
I'm a little ambivalent about this since visitors could put anything in firstname/lastname so it's not much of an auth measure.
It's up to the auth service to decide which data it actually uses.
Possibly we should be passing through other info such as agent circuit ip
Users should not be given the impression that they can modify these items.
This still does not solve the issue where library items cannot be dragged into prims or user inventory any time after they are initially seen.
Curiously, manually copying and pasting still appears to work.
On the surface, this seems to have something to do with library item caching on the client, since deleting the cache allows drag to work again once
Not sure what the exact problem is.
Some items had completely wrong permissions - this is easier than correcting them all.
The ability to set permissions in xml is retained since there are use cases for this (e.g. to create no-mod library scripts)
Library items always need the same permissions, so it doesn't make sense to load them from the xml files. This just opens the door to permissions mistakes.
This matches the ability to disable the memory part
This is controlled through the FileCacheEnabled parameter in FlotsamCache.ini
Default is true, so existing installations are not affected.
Improved fcache command feedback when various caches are disabled.
Re-enabled test for flotsam cache with file caching disabled.
This now creates an avatar but appearance is always cloudy.
Move doesn't work.
Really, creating an NPC should only involve a ScenePresence rather than doing anything with IClientAPI, since an NPC has no viewer to communicate with!
Instead of performing the 4096 check when the region is linked (and subsequently removing the link), leave the link in place and perform the check in the entity transfer module
This allows us to explicitly tell the hypergridder why the teleport failed (region out of range).
It also allows people on regions that are within range (on a large source grid) to teleport.
The Check4096 config parameter in the [GridService] section is replaced by a max_distance paramter in a new [EntityTransfer] section in OpenSimDefaults.ini
Since the parameter is in OpenSimDefaults.ini no action needs to be taken unless you want to increase this limit. It could also be decreased.
The check is being made in the base entity transfer module, since I believe the viewer problem occurs both on extremely large grids and while hypergridding.
RemoteGridService connector. Timeout is currently set at five
minutes. Negative results are not cached.
The result is that operations like send an instant message do
not have to go through the grid service every time.
For the most part, defaults are made to match those already in FlotsamCache.ini.example.
The one exception is that the 48 hour file timeout from the code is used instead of the 0 hours that was in the example file. This can be tweaked if necessary.
Most importantly, the default cache directory is now ./assetcache (as in FlotsamCache.ini.example) rather than ./FlotsamAssetCache (as was the internal code default).
Therefore, if you were using flotasm without using the config file, then please rename your cache directory or start using the ini file and change the default there if you want to keep using your existing cache.
Like "save oar", this saves an iar without assets
This can be useful for backup when you know the required assets will still be present (e.g. you're backing up the assets db separately).
This also bumps the iar format version to 0.3 and 1.2 respectively.
0.3 is backward compatible with previous opensim versions
1.2 is used if the --profile switch is specified. It is only compatible with 0.7.1 presently.
This adds a <assets_included>true|false</assets_included> element to the oar control file, though this is not used on reloading at this time.
This addition is backward compatible with previous opensim releases
This switch stops any assets being saved in the oar.
This can be useful if you're using OAR to backup regions and you know you'll always have the original asset database available.
At the moment, this command just asks the AvatarFactory to perform the existing baked texture check for each avatar in the simulator and returns "OK" or "corrupt".
This is for debugging purposes
Addresses http://opensimulator.org/mantis/view.php?id=5444
Fix is to stop the asset transaction calling UpdateInventoryItem() since the caller is doing it anyway, which is more correct.
This did not effect scripts.
From pure code inspection, it looks like the uuid gatherer may get most asset uuids because the scene object serializer naively pulls non-root parts from all contained scene objects into one mega-object. However, root part uuids may well still be missing, and there may be other odd artifacts from this bug.
It appears that storing the size of the coalescence and the offsets is redundant, since one can work out this information from the position data already in the scene object groups.
This now only happens for the first object (which was the item selected last when the coalesce was originally taken)
This matches the expected behaviour of the environment as seen on the Linden Labs grid.
This structure matches the existing one for SceneObjects and will allow code to be reused by the uuid gatherer, other tests, etc.
Test is not yet fully implemented due to a bug in rezzing coalesced objects where they all get the same name as the item.
Only one object should get the same name as the item, which appears to be the one selected last when the the objects were coalesced in the first place.
This bug will be addressed shortly.
This should happen if the client supplies a task ID with the RezObject call.
The rez goes through the same code as llRezObject(), so the same perms are applied.
Rotation isn't yet preserved, this should be fixed shortly.
This updates prim counts correctly if an object is moved by something other than an avatar (e.g. scripts, region modules)
Create TestMoveOwnerObject() regression test for this case.
However, the calls to the land management module to record prims need to remain, since they were also being used to return owner object lists, etc.
This is probably why prim counts were being done there in the first place.
This fixes the total prim count that the viewer displays when prims are selected - it appears to ignore the total that we pass it and adds up the counts separately.
This applies to adding/removing estate users, groups, managers and bans.
This is the application of the AllEstates_0.5.patch from http://opensimulator.org/mantis/view.php?id=5420
Thanks very much, Snoopy!
WARNING!!!!!
You can TAKE them, but you can't REZ them again. Only the first of the contained
objects will rez, the rest is inaccessible until rezzing them is implemented.
Also, rotations are not explicitly stored. This MAY work. Or not.
This appears to be the more probable explanation for some failures seen. Either we're counting attachments which are temporarily out of bounds (shouldn't be due to the IsAttachment) check or we're counting scene objects which have out of bounds co-ordinates (seems more likely)
Added a prim counts test to reinforce this - shift-copy was no incrementing prim count. This will sometime become a basic scene test.
New code needs to be refactored so we just call SceneGraph.AddSceneObject(). This will happen in the near future.
With this, basic owner prim counts on a single parcel appear to be working fine (with the same previous existing taint calls as used by the land management module).
More work to do.
In order to pass ILandObject into IClientAPI.SendLandProperties(), had to push ILandObject and IPrimCounts into OpenSim.Framework from OpenSim.Region.Framework.Interfaces, in order to avoid ci
Counts are showing odd behaviour at the moment, this will be addressed shortly.
OnParcelPrimCountAdd had the wrong semantics for the PrimCountModule - it was invoked for every entity in the scene, not just new ones, which would screw up the untainted count.
Extend automated test for this scenario.
Media permissions are just meant to be checked when we want to know if a user should be shown the navigation bar or allowed to navigate. It should not be checked when we're setting the media up.
This bug was preventing a user from ever setting any more values if they had unchecked the owner settings.
this is necessary for correct loading. "save iar" always saves in this order so there shouldn't be any problems - these checks are to give better feedback to other systems that may construct IARs.
This should resolve issues where the creator for rezzed objects was being shown as "Unknown user" where previous behaviour was to show the OSP resolved account.
This is being done by parsing the serialized objects and updating the CreatorID if no CreationData exists. This operation might be expensive for sculpties where the sculpt texture is inlined with the object data. Will just have to see.
This relies on the IAR streaming inventory data before asset data (as is currently the case). Will need to introduce more stringent checks for file order on loading (much like JAR zips must start with the manifest file).
This is for IAR loading only. Tests updated to check this behaviour.
We weren't setting the TextureEntryFace.MediaFlags = true when a media texture was set directly via a script. This was being done when the viewer was setting them directly.
child agents in neighbor regions. This means you can extend
the view on a simulator beyond the default 3x3 regions.
This uses a region default draw distance and should be
replaced at some point by the avatar specified draw distance.
That will require more careful, dynamic recomputation of child
agents every time the draw distance changes.
WARNING: this is experimental and has known instabilities. specifically
all regions "within site" should be running the same default draw distance
or agents will not be closed correctly.
This addresses Mantis #4709.
Command "alert" always sends a message to everybody; the variant "alert general" has been removed. Sending messages to one user is done with the dedicated command "alert-user".
This will show the estate for each region, along with that estate's id and the estate owner.
This is temporary because the command output might change.
This commit also converts the estate module from the old to the new region module format
