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.
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
Fix inconsistencies between configuration parameter names and their description names. Changing the configuration parameters for non physical prim size min-max from Nonphys* to NonPhys*.
Please update your OpenSim.ini and Regions.ini to reflect these changes.
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.
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.
Add description and default of false (as before) to OpenSimDefaults.ini
If set to true, this config switch will resend avatar appearance information (a small amount of UUID data, not the baked textures themselves) to other avatars in the sim every 60 seconds.
For me, this has helped with situations where avatars appear persistently grey - the LL viewer sometimes did not appear to request assets the first time the appearance data was sent.
However, this switch will not help with other appearance failure situations (e.g. failure to bake assets).
This setting is experimental but will not have any significant impact on the simulator if turned to true.
and into its own class. The BulletSim data structures track
individual prims as linksets of 1 so most of the prim code is not
different between a linked and unlinked object.
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.
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.
Without this, LL 3.3.1 continually pushes LLInventoryModelFetchDescendentsResponder::error 499 to its log.
This cap will be ignored by older viewers - UDP inventory will work normally.
folder when deleting objects from a scene. The use of the trash
folder causes assets to be created and stored everytime you delete
an object from the scene (slows down the delete and adds mostly useless
assets to your database).
Default is on (use the trash folder) which is the standard behavior.
Value for this setting in OpenSimDefaults.ini (1000) is same as setting in code (1000) so this should have no effect
Thanks to Ovi Chris Rouly for pointing this out.
If velocity reaches 256 in any vector then bad things happen with ODE, so we now clamp this value.
In addition, a falling avatar is clamped by default at 54 m/s, which is the same as a falling skydiver.
This also appears to be the value used on the linden lab grid.
This should resolve http://opensimulator.org/mantis/view.php?id=5882
Naturally, default is true.
When set to false, "phantom" flags on prims can be set as usual but all prims remain phantom.
This setting is for test purposes.
This switch does not affect the collision of avatars with the terrain.
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.
From field experience, we know that simulators can be unstable if a user logs in before the scripts have finished loading.
This commit turns login_disable = true in [RegionReady] on by default which prevents this from happening.
If you want the old behaviour, please copy these section from OpenSimDefaults.ini into OpenSim.ini and set login_disable = false
This is to allow broader subsitution in the future. Currently, the only substitions are \R (for region name) and \\ (for a single backslash)
e.g. "Region (\R) " is the current and continuing default prompt
This renames custom_prompt in [Startup] to ConsolePrompt
PARCEL_GROUP, PARCEL_OWNER, ESTATE_MANAGER and REGION_OWNER can be combined with the existing agent uuid option to limit ossl functions to agents and owner classes.

As discussed in http://lists.berlios.de/pipermail/opensim-dev/2011-October/010599.html and the preceeding thread mails,
the aim of this setting is to avoid overloading the viewer UDP connection where the client is failing to ack packets.
Please mantis any anomalous viewer connection behaviour which wasn't there before.
This had stopped working. However, at the moment it still allows the physics flag to be set even though this has no effect. This needs to be fixed.
Default for this flag is true as previously.
This exactly fits five ODE steps in the default frame time (0.089).
This means that ODE execution time now matches the default minimum frame time.
This eliminates errors between distance travelled as calculated by ODE in clear air and simple extrapolation.
On the old values, ODE would actually do calculations over 0.1 seconds rather than 0.089.
This means that once the avatar is at top speed, no additional packets need to be sent for smooth movement, since no error develops between server and viewer.
This approach replaces the tweaks previously discussed on the opensim-dev mailing list
Settings are at bottom of [Startup] in OpenSimDefaults.ini, override in OpenSim.ini to change
Defaults are the same as previously.
More information to come on opensim-dev shortly.
Feel free to tweak but if you do please don't expect any support unless feedback on certain tweaks is explicitly requested.
Also adds password check to some functions where this was missing and fixes some parameter checking.
This is a patch from http://opensimulator.org/mantis/view.php?id=5715 with a few small unrelated spacing tweaks from me.
Thanks Michelle Argus.
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.
When this setting is false and other defaults haven't been changed, scripts entering the simulator from another sim are automatically restarted but their state is not preserved.
When this setting is true, state that accompanies the script is reloaded (e.g. if a script had a variable i = 1 when leaving the source region, it will still have i = 1 on the destination region).
This setting does not affect crossings when regions are run in the same simulator. In this case, state is already preserved.
