Re: [Opensim-dev] Multi-region OAR format
okay so if i wanted to make an OAR for Bad Wolf Island with a total of nine regions it would have row 1 (south) Southwest, South center , South East row 2 (center) West Center, Center, East Center row 3 (north) NorthWest , North Center, North east and if i wanted to have a 2X4 region then it would be row 1 (south) South West , South Center West, South Center East , South East row 2 (north) North West, North Center West, North Center East, North East and any region without data will create a hole in the sim if the server can be made to handle it i would suggest that a dummy manifest be used to create blank regions (modes would be fixed height, Blend or random) -- Robert L Martin ___ Opensim-dev mailing list Opensim-dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/opensim-dev

Re: [Opensim-dev] Multi-region OAR format
That's an interesting idea. I'm wondering whether this would be slower, however, since OpenSim would have to untar all the data twice: once in the outer OAR, and again in the inner OARs. It might also take twice the RAM, depending on how the untar library works. -- View this message in context: http://opensim-dev.2196679.n2.nabble.com/Multi-region-OAR-format-tp7578162p7578172.html Sent from the opensim-dev mailing list archive at Nabble.com. ___ Opensim-dev mailing list Opensim-dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/opensim-dev

Re: [Opensim-dev] Multi-region OAR format
Robert, I feel that load and save of multiple files simultaneously would be too fragile. And as Oren said, it ends up wasting a lot of space and some processing time for data that is held in common between regions (e.g. assets). I like this proposal, Oren. I should have put regions in separate directories originally but it's easy to say that in hindsight. One thing to watch out for is that OpenSimulator has an option to register multiple regions with the same name, though I suspect that's not a good idea in many contexts and I can't say for sure whether the option even works. So you may have to uniquify region folders with their UUID or similar. I would also prefer to see regions within a separate regions/ top level folder, e.g. regions/region1, regions/region2, etc. In the long term I would like to see all OARs to be saved with region directories, including single regions. However, in the interests of forward compatibility for existing OpenSimulator releases I think it is a good idea to save single regions in the existing structure, with the multi-region structure only being used with the --all flag. In a few releases time the new format can become the default and the old format only saved with an explicit flag. Or perhaps one could call the new structure .moar (I half kid). Something I might consider is whether the locations of other directories (e.g. assets) could be specified within the oar itself instead of with constants such as ArchiveConstants.ASSETS_PATH, though I don't know if that would help much in this case. Or try and think about ways to make oar/iar loading more liberal in what it accepts (following Postel's law). We used to have the same problem with XML loading where only one order of elements would be accepted but I think that has been pretty much eradicated.
