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
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.
Among other things this allows pCampbot to work under Windows since libopenmateverse now ships the same log4net.dll (publicly signed) as OpenSimulator
This also updates the libopenmetaverse embedded libopenjpeg from 1.3 to 1.5.
DLL naming and mapping for non-Windows libopenjpeg changes to remove version number to make future udpates easier and bring it into line with names of other shipped DLLs.
libopenjpeg updates have been made for OSX, Windows (32 and 64 bit) and Linux (32 and 64 bit). Please report any issues.
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.
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.
