G'Day, I've been looking at our minimum python version for the AD DC. We have some patches currently being proposed to help us become compatible with the modern Python3, and one aspect (PyCapsule) would be easier to do if we restricted Samba to requiring Python 2.7 as a minimum. The wrinkle comes from our good friends at Red Hat, which found itself caught with Python 2.6 on RHEL6. Naturally additional python versions can be installed from third parties, just as folks have done for RHEL5 f...

Posting now that I got something to compile (at the expense of breaking OCaml bindings), but I'm open to ideas on how to improve it.

v1 was here: https://www.redhat.com/archives/libguestfs/2019-July/thread.html#00231 The changes address everything that Eric picked up in his review of the first two patches. I have also added two more patches (4 and 5) which respectively fix docs and change int status -> unsigned status, as discussed. Passes make, check, check-valgrind. Rich.

This implements most of what I wrote here: https://www.redhat.com/archives/libguestfs/2019-July/msg00213.html

I think I've addressed everything that was raised in review. Some of the highlights: - Callbacks should be freed reliably along all exit paths. - There's a simple test of closure lifetimes. - I've tried to use VALID|FREE in all the places where I'm confident that it's safe and correct to do. There may be more places. Note this is an optimization and shouldn't

As before, but this one has working Python bindings. OCaml still TBD. Rich.
