It originally looked like mesh terrain would perform better for vehicles
but, after much use, heightmap is the clear winner.
Force terrain implementation to heightmap if the physics region is
larger than legacy region size. This solves running out of memory for
very large regions.
udp texture throttle and move it to the task throttle. Since most
viewers are using http textures, the udp texture throttle is holding
onto bw that could be used for more responsive prims updates. See
the documentation for CannibalizeTextureRate in OpenSimDefaults.ini.
Option is disabled by default.
Changed UuidGatherer to use 'sbyte' to identify assets instead of 'AssetType'. This lets UuidGatherer handle Materials, which are defined in a different enum from 'AssetType'.
This includes additions to Warp3D:
Optional rendering of mesh and scupltie prims (INI parameter. Off by default)
Texturing of large prims (INI parameter. On by default)
Better garbage collection
This is done by adding <loadFromRemoteSources enabled="true" /> to the execute *.config files.
This tells .NET 4 to trust the DLLs, which is safe in our case since we are not loading DLLs from locations that untrusted users may specify

As far as I know, CAS policy checks have never been performed in Mono
The BulletSim plugin is higher performance and has a better implementation of vehicles amongst other things.
Many thanks to Robert Adams for making this possible with the enormous amount of work that he has done on this plugin.
If you want to continue using ODE, set physics = OpenDynamicsEngine in the [Startup] section of OpenSim.ini

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
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 can currently only be activated with the console command "debug stats record start".
Off by default.
Records to file OpenSimStats.log for simulator and RobustStats.log for ROBUST
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.
Default off, for the moment, until more testing.
Add separate thread and center-of-mass flags to OpenSimDefaults.ini.
Clean up comments in OpenSimDefaults.ini.
This makes stars appear more realistically rather than as massive chunks due to the missing IMG_BLOOM1 asset from the viewer.
Thanks to YoshikoFazuku for supplying the star asset which I then uploaded via a viewer and extracted as JPEG2000.
Thanks also to Ai Austin for helping this process along.
See http://opensimulator.org/mantis/view.php?id=6691 for more details.
Add option to set minimum fee for publishing classifieds. Many viewers have a
hard coded minimum of 50, which makes publishing classifieds fail where grids
have no economy. This allows the grid to set the minimum fee to a suitable
value for their operation.
The option is located in the [LoginService] section and defaults to 0. The
value is sent as "classified_fee" in the login response.
which recompute GImpact shape bounding box after creation as Bullet
doesn't do that itself (something it does for nearly every other shape).
Now, physical prims without cuts become single mesh convex meshes. Physical
prims with cuts become GImpact meshes. Meshes become a set of convex
hulls approximated from the mesh unless the hulls are specified in the
mesh asset data. The use of GImpact shapes should make some mechanical
physics more stable.
Adding some viwer supported url settings for destination guide and avatar picker apps. URL for the destinations should be: "secondlife:///app/teleport/slurl"
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).
UnsafeQueueUserWorkItem is so called because it allows the calling code to escalate its security privileges.
However, since we must already trust this code anyway in OpenSimulator this is not an issue.
This option allows the simulator to specify that the cancel button on inter-region teleports should never appear.
This exists because sometimes cancellation will result in a stuck avatar requiring relog.
It may be hard to prevent this due to the protocol design (the LL grid has the same issue)
In small controlled grids where teleport failure is practically impossible it can be better to disable teleport cancellation entirely.
* Add zero length blocks to the new packet blocks to remain compatible with older viewers and avoid a NullRef when _packets_.cs calls the Length parameter.. which adds up the Length property all of the blocks.
This change also corrects the setting names - they were actually wrong (though the text in {} was correct).
If there are settings in [Startup] they will continue to be used and anything there will override settings in [AccessControl]
This is not widely used (may even be currently broken), only allows very poor quality voice (not the fault of FreeSwitch)
and requires a complicated Freeswitch setup.
Having it on but not configured results in spurious warnings in the logs
Existing map settings in [Startup] will continue to work, and if present will override anything in [Map]
However, the proper place for such settings would now be [Map]
This is to reduce the use of [Startup] as a bag for non-generic settings which should really go in sections, in common with other settings.
This commit also extends Diva's previous work to allow a default setting to be given when looking at multiple sections for settings.
funny unit that is 100 times real density (default 1000).
Fix avatar drifting slowly when stationary flying.
Fix for physical prims getting corrected for being under terrain when it was
just its geometric center that was below terrain.
Add PreUpdatePropertyAction allowing plugable modifiction of phys
parameters returned from Bullet.
Fix an exception setting GravityMultiplier on initialization.
Update DLLs and SOs for good measure (no functional change).
invisible barriers in sculptie doorways (Mantis 6529).
Bump up level-of-detail for physical meshes to 32 (the max). This
fixes the invisible barriers that showed up in prim cut arches.
NOTE: the default LOD values are removed from OpenSimDefaults.ini.
If you don't change your OpenSimDefaults.ini, you will continue
to see the arch problem.
on a moving object.
Rearrange pre/post action subscription code to put more in locks.
Add meshmerizer params to BulletSimTestUtil scene creation (and fix line endings).
Rebuilt version of DLLs and SOs with cleaned up code and no profiling for sure.
to the fetch URL to return the data in JSON format. Also adds a simple
'sim.html' that uses JavaScript to display the JSON data. Not pretty
but an example.
* The only thing that had an issue was when creating a new RigidBody, BulletXNA didn't know the type SimMotionState and the upcast type is unknown in the constructor. Therefore, I had to update the IMotionState with a new method 'SetBody'. All of the duplicated type information has been removed and BulletXNA is not relying on any non-standard types external to the library.
This setting controls whether scripts are stopped by aborting their threads externally (abort) or by co-operative checks from the compiled script (co-op)
co-op should be more stable but this option is experimental.
If moving from co-op to abort, existing script DLLs will need to be recompiled.
This currently can only be done manually, either by setting DeleteScriptsOnStartup = true for one run
or by deleting the script DLL* files in bin/ScriptEngines/<region-id>/
One can move from co-op back to abort without recompilation, but reverting back to co-op again will need script recompile
Necessitated allowing simulator and physical position of a body to
get out of sync since Bullet assumes that <0,0,0> is the center of mass.
Update DLLs and SOs for the UpdateChildTransform so positions of
individual prim in a linkset can be implemented.
Default is 1000, as has previously been the case.
This parameter exists for further debug work concerning mono 2.10 crashes that may be related to locks not being removed on Thread.Abort
static objects by more restrictive selection of objects that collide
with static objects.
Rename collision mask fuctions from 'filter' to 'group' so it is clear
what is being set.
Rename BulletSimAPI.SetCollisionFilterMask() to SetCollisionGroupMask to match above.
Restore passing of time step to linear and angular motion component routines.
Use buffering vehicle physical parameter get/set routines consistantly.
Make range enforcement clearer by using ClampInRange() function for parameter setting.
Remove commented out experimental vehicle calculations.
This reduces base memory churn of every client connection, improving the garbage collection situation.
The effect is a significant portion of base load (an avatar standing still on a completely blank island)
but will probably still be swallowed up by other memory use on active regions.
Tests have shown no noticeable impact on speed of processing incoming packets, though setting remains
in case a switch back is needed.
Setting this to false will block all restart requests from the viewer even if they are otherwise legitimate.
One use is to block region restarts if necessary whilst restart functionality remains buggy or triggers bugs in modules,
though these should be fixed as soon as practicable.
Default is true, as has been the case historically.
Simple attempt to make avatars better shaped.
Replace parameter 'avatarCapsuleRadius' with 'avatarCapsuleWidth'
and 'avatarCapsuleDepth'.
More tweeking to avatar height calculation. A little better but
short avatar's feet are above the terrain and tall avatar's feet
are a little below the ground.
nant_0.91~alpha2+dfsg-3_all.deb in Ubuntu 12.04 and earlier actually ignored these due to a bug
However, nant 0.92~rc1+dfsg-2 in Ubuntu 12.10 fixes this bug (possibly https://github.com/nant/nant/pull/39).
Which makes nant time-consumingly copy these files when the aren't actually used.
Tested removal of <copy> on both nant 0.91 and nant 0.92
Will be submitting this patch to prebuild project for comment though I suspect there's nobody there to pay attention.
This allows a closed grid to delete asset types other than maptile remotely.
Only operational if AllowRemoteDelete = true also.
Defaults to false - do not enable if anybody other than you can make asset service requests.
This is because macosx mono is 32-bit and this can't p/invoke 64-bit binaries.
However, the reverse is also true.
If OpenSimulator stops working for you then please complain! Long term alternative is probably to build a fat binary with both architectures.
This retrieves and caches information from the PresenceService to only send messages to online users.
This is reported to much improve performance for large groups where most users are offline.
Cache is 20 seconds to balance requests against users not receiving messages until cache updates.
This is an alternative to an approach where login/logout notification is sent directly from simulator to groups service.
However, I'm not convinced that this PresenceService approach is actually better. Needs more thought.
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.
We can provide modular ini for connectors...
look for our configuration in the following places...
1) in the default ini/-inifile
2) in the named file (ConfigName) located in the configured directory
(see Robust[.HG].ini [Start] section for ConfigDirectory)
3) in the repository named in the connector (ConfigURL)
In this case, the file will be written into the configured
directory with the specified
See example connector/service @ https://github.com/BlueWall/SlipStream
for testing.
Rearrangement and cleanup of shape collection code. Much more readable.
Enabling and use of collision filters and masks.
Addition of ID to body creation BulletSimAPI calls so always set in
shape for collision reporting.
Change default of ShouldSplitSimulationIslands and ShouldRandomizeSolverOrder
from 'false' to 'true'. When 'false', this suppresses NO_CONTACT_RESPONSE
which makes volume detect fail.
This controls how many undo steps the simulator will store for each prim.
Default is now 20 rather than 5 as it briefly was.
The default number could be increased through this is a memory tradeoff which will scale with the number of prims in the sim and level of activity.
This resends appearance uuids to avatars in the scene once a minute.
I have seen this help in the past resolve grey appearance problems where viewers have for unknown reasons sometimes ignored the packet.
The overhead is very small since only the UUIDs are sent - the viewer then requests the texture only if it does not have it cached.
This setting will not help with cloudy avatars which are usually due to the viewer not uploading baked texture data or uploading something that isn't valid JPEG2000
This is because libopenjpeg 1.5 appears to require a minimum of glibc 2.14, whereas at least one fairly recent distro (openSUSE 11.4 from 2011-03-10) only has glibc
Further investigation pending.
