|0007642||opensim||[REGION] OpenSim Core||public||2015-07-16 09:01||2015-07-17 15:06|
|Product Version||master (dev code)|
|Target Version||Fixed in Version|
|Summary||0007642: meshes - OAR compatibility problem opensim version|
|Description||I was running on OSG a varregion mainly with meshes using OSG opensim-05232015.v0.8.2.abb3bb6.|
Because of some memory problems (0007593)I decided to go back to opensim v0.8.1 stable. Surprise : parts of meshes were missing. I loaded my oars with the same result.
I changed again for to 05232015.v0.8.2.abb3bb6 and everything was perfect.
Does that mean that you can't use an oar with an opensim version earlier than the one you used to make the oar ?
|Steps To Reproduce||Create a varregion with meshes with a v.0.8.2|
Create an oar
Run the region Under 0.8.1
Check if parts are missing
Load the oar to see if the result if the same
If part are missing, run again 0.8.2 : everything is correct
|Tags||No tags attached.|
|Git Revision or version number|
|Run Mode||Grid (1 Region per Sim)|
|Environment||Mono / Linux64|
|There have been no changes to OAR between this time that I can recall. However when you load an oar make sure that you type "backup" on the region console after the load oar completes. Then restart the simulator once the backup completes. If you restart a region immediately after load oar completes without forcing the backup or waiting long enough you will find that content is missing once it restarts.|

Thank you Neb, I will try that.
Nevertheless parts of meshes disappear when "downgrading" from 0.8.2 to 0.8.1 without using oars, just restarting the region with the older version. The meshes were created under 0.8.2, I precise
|This is likely an asset problem. It's possible that the meshes could have only been in your viewer cache or some other cache and never made it to the grid asset service or were pulled from there when the oar was created. I'd think other assets such as textures would be affected also but maybe you haven't noticed yet, or perhaps they are still in your viewer cache.|

You are right Dahlia. It's stupid of me. I never thought that the cache can react differently depending on the opensim version. Moreover this happened only on a varregion, all the regular region were OK.
Thank you and sorry for not having thought to the cache.
|Wonders aloud if a "backup" should be forced by the "load oar" before it reports success?|

I would tend to agree with Ai on that one. I don't see any reason why loading an OAR should not force objects to be persisted to the database by default.
|This might make sense, assuming the oar was dependent on a backup. I believe they are independent though and whether a backup has occurred should not affect an oar in any way. However, I haven't verified this recently by looking at the oar code.|
