Hi,
Now Robert seems to be back from his break, I'm just going to mention the
potential footguns I found here in case they need sorting out. I've got a
reasonable solution for the issue I was having, so that doesn't really need
discussing any more, but it seems sensible to me that OSG might want to avoid
letting people get into such a situation in the first place.
When a context is destroyed, the object cache can still have things in
it that need releasing. It might be a good idea to automatically release things
in the object cache when a context is destroyed. Even in the single-view case,
it's not best practice to rely on the GPU driver to clean up everything when a
context is closed, so this might be helpful for anything that loads stuff from
files.
If a composite viewer has a cleanup operation, it's only called when
the composite viewer is destroyed, and not when associated contexts are
destroyed. This should maybe be changed so that it happens when a view is
removed, too, or maybe it should be possible to set a cleanup operation on the
context objects themselves.
The static default font doesn't get released when a context is
destroyed. I don't know everything about OSG, so maybe there's a list of static
OSG objects that it should be added to, or maybe having static OSG objects is
just a bad idea.
Cheers,
Chris
