I seem to be very lucky this week, I ran into another very nasty bug. :( I narrowed it down to this section of code in my application:
OSG::NodePtr model_xform = getModelXform(modelId); OSG_ASSERT(model_xform != OSG::NullFC && "Model xform is NULL"); OSG::commitChanges(); OSG_ASSERT(mRootNode.node()->findChild(model_xform) != -1); mRootNode.node()->subChild(model_xform); OSG::commitChanges(); // loop forever model_xform is a transform node with a textured model under it made up of a screen size LOD and several sub-trees of of material groups and geometries (data loaded from a VRML model). When I call the final commitChanges, OpenSG becomes stuck in an infinite loop. I added some debug code and found that the ContainerChangeEntry::commitChanges keeps getting called over and over for the same field container. In all cases it was looping over and over on an Image container. With a bit of investigation and some remote support from Dirk, we found that if I commented out the contents of Image::changed then the code would not loop forever. So for now I have just removed that code and will keep running without it until I can get some advice from someone on what may be causing this problem. Note: I have not been able to replicate this is a simple test case so I don't have any code to show you. The code I am using right now should be doing all loading from a single thread and is only using a single aspect. All file data is from a VRML file that was converted into an .osb file as part of a preprocessing step. I know that we are pushing OpenSG 2.0 in some ways it has not bee used before, and I am very interested in helping to find this bug and any other related bugs. Please let me know if there is anything I can do to assist. Thanks, Allen ------------------------------------------------------------------------- Take Surveys. Earn Cash.
