I usually put my mypy config in apyproject.toml
file these days, but amypy.ini
file feels like it makes more "sense" unless we're planning on adding other linters/formatters to checkclinic.py
in the future

We're deliberately pinning to an older version here, in order to test that dependabot updates are working on this file, as per@hugovk's suggestion in#104421 (comment)

So, thesestr | None
are now starting to cause frustrations, as I gradually add typing to other parts of clinic.py. Since there are no guards anywhere, I obviously get errors and warnings aboutstr
plusNone
, etc. Wecould change the defaults to the empty string, but that can also create a lot of havoc.

Add a basic mypy check to
clinic.py
in CI (and add some initial type annotations, so that the mypy check passes).The check will run:
main
Tools/clinic
directory, and pull requests that touch the workflow file itselfworkflow_dispatch
.When itdoes run, mypy will only check files inside
Tools/clinic/
. All other files will be excluded from the mypy check in CI.The mypy configuration is also deliberately lax, to begin with: only a few of the stricter settings are enabled. This will allow us to make use of "gradual typing": mypy will only check functions inside
Tools/clinic/
that we've added annotations to. It will assume all other functions are to be ignored by mypy, for now; we will therefore be able to gradually increase the level of type annotations inside this directory.
