This Week in Open Sim Development Week Ending Saturday December 13th 2008

This week in OpenSim ( r7633 – r7707 )

General news

• At the time of this post we are using r7728

Features & bug fixes

• Teravus made linked prims a single body when using the ODE physics engine.  He also fixed a bug that would cause the physics representations of prims to be scattered when an object was linked (r7633).
• idb fixed a bug where big startup database migrations were getting terminated after 30 seconds (r7641).
• jonc contributed a patch that means that RAW terrains are imported into OpenSim in the same orientation as they were downloaded from the Linden grid (via the download RAW terrain button in the estate dialog of the Linden Lab Second Life viewer).However, this does mean that any terrains saved in RAW format before this revision will now be flipped around the y axis when imported.  To fix this, jonc also contributed a patch that allows one to execute the command “terrain flip y” on the console which should fix this (r7654).
• nlin contributed a patch that fixes a rare race condition on the ODE physics engine when an avatar’s capsule is created/altered/destroyed when another ODE operation has locked the space (e.g. during collision detection).  One symptom of this was the error “ODE INTERNAL ERROR 2 (X) invalid operation for geom in locked space…” (r7659).
• MW repaired the facility to run a script containing OpenSim console commands on region shutdown (r7662).
• sdague changed the default scripting engine to be XEngine instead of DotNetEngine.  In the past half a year, XEngine has received more development attention and appears to have better performance (r7678).
• Diva contributed a patch that may fix some of the current teleport issues (notably issues on an A -> B -> A teleport sequence).  This patch upgrades the protocol version from v1 to v2.  OpenSim regions will need to upgrade before they can connect to region servers running this revision (r7707).

Infrastructure

• justincc worked on user profile cache and inventory related tests.
• MW started on work to move the current Second Life protocol specific file transfer code into the LLClientStack.
