This Week in OpenSim Dev – week ending Saturday 7th November 2009 November 9, 2009

Posted by justincc in opensim, opensim-dev, opensim-news, secondlife, twiod, virtual-environments, virtual-worlds.

Hello everybody. This is a short summary of OpenSim development for the past week up until the end of last Saturday.  The letters in brackets after bug and feature points are the Git revision identifiers in which the work appears.  We only give the first 6 characters of each revision but this should be enough to identify it.

The changes described here appear only in OpenSim’s cutting edge Git ‘master’ branch.  Please do not attempt to use code taken directly from ‘master’ in any production environment.  At particular points in time this in-development code may not work or may even cause data corruption.  If you are not a developer or tester, please treat this summary instead as a preview of what will be coming up in the next release.  The latest official release is OpenSim 0.6.7 (released on 14th October 2009).

This week in OpenSim ( 711dde – 5300e8 )

General news

  • None this week

Features & bug fixes

  • CasperW submitted a patch that fixes a failure in the Remote Admin shutdown method (f4e980).
  • jhurliman fixed some scene related race conditions.  This may increase stability when manipulating scene objects (192794).
  • Melanie reverted XEngine script loading to occur serially rather than in parallel.  This may reduce script engine failure. The original problematic change was probably introduced after 0.6.7 was branched (001308).
  • Melanie improved inventory data retrieval by clients from a region (30a241).
  • Revolution contributed a patch to implement friends permissions (ability to see where a friend is, edit their objects, etc.).  Melanie made some further changes to activate this (b09857).
  • I added the ability to save inventory items and folders containing a “/” character to an Inventory Archive (IAR).  Previously, such inventory nodes would cause “load iar” to fail, since / is also used as a path separator (345ddc).


  • Dahlia updated prim collision meshing.
  • Adam started adding an additional scene monitoring framework.  The data can be seen by typing “monitor report” on the console.  It may be that this needs to be combined with/supersede the data shown by “show stats”.
  • Melanie disabled the CAPS inventory request mechanism.

Thank you for the updates Justin!

> It may be that this needs to be combined with/supersede the data shown by “show stats”.

It’s a replacement. Show stats is oriented heavily towards the info the viewer is capable of displaying — which misses a whole trove of data that is more applicable to OpenSim, like thread count, etc.

Actually Adam, I think you might be thinking of Teravus’ stats facility. “show stats” hooks into an older facility in OpenSim.Framework.Statistics that also records some simulator level stuff (such as number of asset requests). However, OpenSim.Framework.Statistics is an older facility and I think there are more agile ways to do it.

So effectively we now have three different statistic collection mechanisms 🙂
