Wonder why ofborg-eval-package-list never failed with the previous commits (when it should have).

Edit, hours later: but it did for the same type of problem just now...?

I don't like that OfBorg added the clean up label, though I don't think it gives specifics as to why. 😕

As far as I know, I fixed every issue that caused packages to not eval, so I'm not sure what else it would be adding that for (even if it should fail for that)...

don't worry about it. I am not sure what triggered it but maybe the treewide change.

As it is now, the unittest hook should be added to checkInputs, but after https://github.com/NixOS/nixpkgs/pull/185406 it needs to go to nativeCheckInputs.

Fixed.

This broke tests in .bitstring: https://hydra.nixos.org/build/187598212 (the "treewide" commit, according to my bisect)

[winterqt]

Yes, someone already noted that -- there's a quick fix but also a more proper one that should be upstreamed. See https://matrix.to/#/!kjdutkOsheZdjqYmqp%3Anixos.org/%24_WKyurbQoNXb49piMvNidpULeGz7zFJh-LFM4HoAttE

Other regressions probably won't have significant impact, but let me post them here anyway, in case someone's interested:

I made #187778 to fix regressions (drafted until latest eval completes).
