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.
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.
This is necessary because commit 8131a24 (Tue Mar 27 10:08:13 2012) started passing the config section name rather than hardcoding "AssetService"
This meant that the HG external-facing asset service tried to read ConnectionString from [HGAssetService] rather than [AssetService].
On SQLite, not finding this meant that it fell back to [DatabaseService], which is set for OpenSim.db rather than Asset.db.
Therefore, all external asset requests returned null.
Solution taken here is to create an [HGAssetService] section with the same ConnectionString as [AssetService].
This bug does not affect normal MySQL/MSSQL config since they use the [DatabaseService] connection string anyway.
Addresses http://opensimulator.org/mantis/view.php?id=6200, many thanks to DanBanner for identifying the exact problem commit which was very helpful.
This was a regression from OpenSimulator 0.7.3.1 which did not contain this bug.
This also fixes computation of avatar mass.
Added parameter MaxPersistantManifoldPoolSize.
Fixed a parameter setting bug which caused crashes of there were
more than 400 or so physical objects. I tested up to 5000.
Updated BulletSim DLLs and SOs.
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.
