Re: [osg-users] Text Crash On Main Thread While DB Pager Unrefs Font From Temp Object Cache

More generally I'm not convinced that we need to deprecate the none ref versions. I'd be inclined towards just documenting that multi-threaded reads should use the Ref versions. It might not be convincing to have to go back to the code base and remove these unsafe sections of code, but

Re: [osg-users] Text Crash On Main Thread While DB Pager Unrefs Font From Temp Object Cache

Robert, I just wanted to respond with my investigations and observations. I sounds like the lack of a readRefFontFile() is a potential problem. In the case of include/osgDB/ReadFile there are readRefNodeFile() etc. functions that pass back a ref_ptr rather than a C pointer, and are all

Re: [osg-users] Text Crash On Main Thread While DB Pager Unrefs Font From Temp Object Cache

Hi Ryan, I sounds like the lack of a readRefFontFile() is a potential problem. In the case of include/osgDB/ReadFile there are readRefNodeFile() etc. functions that pass back a ref_ptr rather than a C pointer, and are all safer in multi-thread situations where object cache is in play. Could you
