Can't find the run CI button for the new GitHub interface. Guess I'll switch back to approve, but that's odd that it seems to be missing... (Edit: forgot to check the checks tab, maybe it moved there? Too late now to check.)

I'm not sure using a dependency like this will work this way. Scikit-build isn't required to be installed when it rebuilds. So our dependency might not be there. That's why this file doesn't use any dependencies.

I think that's a known issue with the new merge experience.

Hmm, I could make something simple with fcntl and gate to Unix only? Or we could vendor?

[henryiii]

Unix only would at least be better than the status quo. Vendoring would be hard since we don't even have scikit-build-core present in the user's environment after the editable install.

Pretty sure get_requires_for_build_editable is not what we need, we need to add dependencies to the dependencies itself. Maybe it's okay to do that, since editable installs aren't redistributable?

Thanks for the quick review. I pushed a Unix only fcntl lock based on filelock's implementation.

Thanks!
