Justin, I filed a Mantis entry for the timer_dictionary.patch. http://opensimulator.org/mantis/view.php?id=3311

Nice work, Dan, very useful stuff. Is the scenegraph_dictionary.patch code not already present in EntityManager (albeit possibly unused, I've not looked closely)? If not, would it be better incorporated into there and do you plan on extending the patch into a complete implementation (e.g. localID -> SOP mapping removal as well)? timer_dictionary.patch on the other hand looks like a complete implementation. Is this a patch that could usefully be applied in its current state? > > > > > > > *Dan lake* > > Network Software Engineer > > Network Technology Lab > > Corporate Technology Group > > ( 503.712.8318 > > * dan.l...@intel.com > > > > > > > ------------------------------------------------------------------------ > > _______________________________________________ > Opensim-dev mailing list > Opensim-dev@lists.berlios.de > https://lists.berlios.de/mailman/listinfo/opensim-dev -- justincc Justin Clark-Casey http://justincc.wordpress.com _______________________________________________ Opensim-dev mailing list Opensim-dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/opensim-dev _______________________________________________ Opensim-dev mailing list Opensim-dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/opensim-dev
