Fix collision code to properly sense mega-region children regions as terrain.
When setting an object physical, reset all the physical properties (friction, ...).
Many changes to BSDynamic for readability and commentary.
Linkset hacking for vehicles: don't over mass the root prim.
Add parameter for link constraint solver iterations.
Correct uses of timestep in timescale calculations for vehicles.
Reorganize code/logic for making objects static and dynamic for readability
and use of API2.
Changed most calls in BSPrim to use API2 calls (the new way).
Avatars do not generate default Bullet collision events but do call up
to the simulator for every avatar. Reduces overhead.
Objects added to collision list only if they are processing collisions.
Reduces overhead especially for large numbers of avatars.
Generalize call for water height to GetWaterHeightAtXYZ().
Catch and correct exception getting terrain height when out of bounds.
Correct race condition in Terrain Manager where creation wasn't at taint-time.
Add API calls for constructing compound shapes.
Move NeedsMeshing() logic into object class.
Reorganize logic for object meshing to reduce rebuilding of meshs/hulls.
Make AssetServiceConnector return more useful data on failure, such as what DLL it was trying to load
Allow LocalAssetServiceConnector.GetData() to work without a cache present, as works for the other lasc Get* methods.
This is to resolve a problem where an asset marked as local but not temporary but still used in the scene would be removed.
The timed expiry scan no longer tries to refetch assets from the scene that are not currently in the cache - this is not helpful since it just drags a lot of data into the cache that may never be referenced.
This removes the DeepScanBeforePurge option since setting this to false will introduce the above problem. This previously had a default of true.
Merged ArchiveWriteRequestPreparation.cs and ArchiveWriteRequestExecution.cs. This simplifies the code, and it's faster to write each scene to the archive as it's found rather than all at once at the end.
'Body' to 'BSBody' for disambiguation when reading code.
Complete the API2 interface so nearly all methods on bullet
classes are available to the managed code. The efficient
single call simulation step is kept in place while all
other creation/destruction/parameterization can be done
in the managed code.
Move the addin information from attributes in the source file to the CoreModulePlugin.xml, which is the standard. This will help us automate addin version dependency information when we make new OpenSim releases.
Manually calling GC.Collect() really shouldnt' be necessary and is generally regarded as a bad idea.
A GC should occur anyway pretty shortly afterwards.
However, can leave this in development code for now to see if it does actually make a significant difference rather than simply doing a GC a little earlier.
Viewer LL 3.3.4 and before sometimes fail to properly redisplay dynamic textures that have a small data length compared to pixel size when pulled from cache.
This appears to happen when the data length is smaller than the estimate discard level 2 size the viewer uses when making this GetTexture request.
This commit works around this by always regenerating dynamic textures that fall below this threshold rather than reusing them if ReuseDynamicTextures = true
This can be controlled by the [Textures] ReuseDynamicLowDataTextures config setting which defaults to false.
This is because recent viewers (3.2.1, 3.3.4) and probably earlier ones using the http GetTexture capability will sometimes make such invalid range requests.
This appears to happen if the viewer's estimate of texture sizes at discard levels > 0 (chiefly 2) exceeds the total texture size.
I believe this does not normally happen but can occur for dynamic textures with are large but mainly blank.
If this happens, returning a RequestedRangeNotSatisfiable will cause the viewer to not render the texture at the final resolution.
However, returning a PartialContent (or OK) even with 0 data will allow the viewer to render the final texture.
Second Life seems to have introduced a bug, as we have confirmation that SL
behavior changed recently and changed in contradiction to their stated intention
This appears to be another of the bugs SL is notorious for. Signpost and I have
decided to back this out until SL's intention becomes clear.
This reverts commit f7b88d1c40.
Major rework of terrain management which finally makes mega-regions work.
Update heightmap of terrain by rebuilding the terrain's body and shape.
There is a problem with just replacing the shape so this workaround
will do for the moment but it will need to be resolved for
mesh and hull switching.
Update DLL API for new terrain and shape/body pattern methods.
Terrain creation and modification uses new shape/body pattern.
Move debug logging callback set to initialization call so logging
is per physics engine.
Moved all terrain code out of BSScene and into new BSTerrainManager.
Added logic to manage multiple terrains for mega-regions.
Added new functions to BulletSimAPI to match the library.
Moved all of the terrain creation and setup logic from C++ code to C# code.
The unused code has not yet been removed from either place. Soon.
Moved checks for avatar above ground and in bounds into BSCharacter.
If true, this setting reuses dynamically generated textures (i.e. created through osSetDynamicTextureData() and similar OSSL functions) where possible rather than always regenerating them.
This results in much quicker updates viewer-side but may bloat the asset cache (though this is fixable).
Also, sometimes issue have been seen where dynamic textures do not transfer to the viewer properly (permanently blurry).
If this happens and that flag is set then they are not regenerated, the viewer has to clear cache or wait for 24 hours before all cached uuids are invalidated.
CUrrently experimental. Default is false, as before.
Intended for use if there are future issues with mono crashes whilst generate dynamic textures.
This test is triggered via a new test-stress nant target.
Not run by default.
type for an HTTP request. Since the "official" LSL function limits
the use of the response type, it is implemented as osSetContentType
with a string for the content mime type and a threat level of high.
With this function you should be able to implement rather functional
media-on-a-prim application with much less difficulty.
This prevented more than one additional ordinary folder from being created in the base "My Inventory" user folder.
Added regression test for this case.
Switched tests to use XInventoryService with mostly implemented TestXInventoryDataPlugin rather than InventoryService
Disabled TestLoadIarV0_1SameNameCreator() since this has not been working for a very long time (ever since XInventoryService) started being used
since it doesnt' preserve creator data in the same way as InventoryService did and so effectively lost the OSPAs.
However, nobody noticed/complained about this issue and OSPAs have been superseded by HG like creator information via the --home save oar/iar switch.
Disabled (status quo) by default.
This flag makes the dynamic texture module reuse cache previously dynamically generated textures given the same input commands and extra params for 24 hours.
This occurs as long as those commands would always generate the same texture (e.g. they do not contain commands to fetch data from the web).
This makes texture changing faster as a viewer-cached texture uuid is sent and may reduce simulator load in regions with generation of lots of dynamic textures.
A downside is that this stops expiry of old temporary dynamic textures from the cache,
Another downside is that a jpeg2000 generation that partially failed is currently not regenerated until restart or after 24 hours.
This is to accomodate situations where viewers will create more than one 'type' subfolder (e.g. calling cards)
But at the same time to prevent multiple such 'system' folders (those in the base "My Inventory" user folder).
This also makes GetFolderForType() only return a folder in the base "My Inventory" folder, if such a type folder exists
This doesn't affect any core OpenSimulator code since all callers were passing true anyway
But it allows region modules to create objects that are never persisted.
Now whatever remaining health the avatar has is displayed (float).
This will be 100% (100.000000) if no damage has occurred (as what the viewer should really be seeing anyway).
Returns -1.000000 if the avatar is not found.
Returns the amount of health (in an integer) that an avatar has left in the scene.
If an avatar is not found or safe is enabled on a region, -1 is returned.
Example usage:
default
{
touch_end(integer _t)
{
key agentID = llDetectedKey(0);
osCauseDamage(agentID, 50);
llSay(0, llKey2Name(agentID) + " has " + (string)osGetHealth(agentID) + "% health left.");
}
}
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 resolve a reported issue in http://opensimulator.org/mantis/view.php?id=6232
Here, the land management module is using OpenSim.Framework.Cache (the only code to currently do so apart from the non-default CoreAssetCache).
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.
no effect on non-logging running.
Capture region name that is passed to the physics engine and use
it for detail logging file name prefix.
Fix problem with avatars dropping when flying across region boundries.
property multiple times every time Update is called.
This eliminates zillions of settings which is better for BulletSim.
The should be no functionality change.
