There are two possible approaches to fixing this: we could cherry-pick
https://github.com/psf/black/pull/4671 and
https://github.com/psf/black/pull/4745/commits/c696b9d80c3bbbf7849515f082e1542f58add52a,
or we could upgrade to black 25.9.0 now that python3-pytokens has made
it through NEW. I prefer the latter option on general principles.
However, in either case, I found that I needed to temporarily disable
building black with mypyc (by commenting out `export
HATCH_BUILD_HOOKS_ENABLE=1` in debian/rules), because both the patched
25.1.0 and black 25.9.0 have many test failures with mypy 1.18.2 in
testing/unstable, to the extent that I suspect the resulting package
would be broken.
I see somebody seems to have started working on upgrading to a new mypy
upstream (https://github.com/psf/black/pull/4749), but the commits so
far don't seem relevant to this. I haven't exhaustively checked the
upstream main branch, but I don't immediately see anything relevant
there either.
Michael, do you think it would be acceptable to disable building with
mypyc for now, or do you have any better ideas? Let me know if you need
me to push my work in progress somewhere.
Thanks,
