This week in OpenSim Dev – week ending Saturday 12th March 2011 March 16, 2011

Hello everybody.  This is a summary of the last week of development in OpenSimulator.  Except where otherwise specified, 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.  Sometimes 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 (released on Saturday 11th September 2010).

The letters and numbers in brackets after some entries tell you the latest git commit to which they apply.

This week in OpenSim ( 9923a2f – f6f8d12 ).

General news

  • I’d like to welcome James Hughes (aka BlueWall from BlueWall Information Technologies) as the newest OpenSim core committer.  Bluewall has contributed a number of good patches to OpenSim over the years, and is involved with a number of surrounding projects, such as the Fortis distribution.  Welcome aboard!

Features & bug fixes

  • I updated the MySQL .NET library used by OpenSim to version 6.3.6.  Hopefully, this will fix a bug where some long running data migrations in Git master code could fail when OpenSim was upgraded.  The MySQL DLL libraries in release versions of OpenSim (e.g. do not contain this bug (3e5b1a1).
  • I fixed OpenSim Inventory Archive (IAR) loading so that if a creator name has been recorded in the IAR through the OSP (OpenSim Profile) mechanism, and an account with that name exists on the target system, then the item is reassociated with that creator.  This is a far from perfect system but somewhat better than nothing.  This matches previous behaviour that has been absent from OpenSim for a good few months (b821f74).
  • Mic made map search work with viewer 2.  However, only the SimianGrid and hwios service/web interface systems currently supply the necessary mapserverurl login response and a webservice endpoint that supplies images with the filenames that the viewer expects (836ab6b).


  • I updated the NUnit testing framework to version 2.5.9.  This performs somewhat better and provides better infrastructure for tests (e.g. asserting that exceptions are thrown from certain operations).
