@jaraco I'll need some assistance, perhaps during the sprints, to figure out why there are so many errors/failures. The test suite didn't pass for me locally even with a pristine copy of the repo without my changes, but these changes seemed to have introduced tons of additional errors and failures.

Just a wild guess, but maybe it also needs to be bootstrapped in https://github.com/pypa/setuptools/blob/main/bootstrap.egg-info/entry_points.txt?

I have no clue. Can you make sense of the errors in CI? It's like at least some of them have nothing to do with this change.

For some reason when you run tox -e vendor some directories ended up excluded. I am not sure why that happened, but when I run tox -e vendor in my machine, as a result it creates these new files that are not added to the PR yet:

# Python 3.12 (pipx run --python python3.12 tox -e vendor)

I think these files need to be included.

There also seems to be a problems with static check:

Maybe this solves the problem:

I am still having a look on the other errors that appeared.

[agronholm]

I have one final problem, with the mypy exclude not working for bdist_wheel_testdata.

[agronholm]

We debugged this with @webknjaz and concluded that we need to prevent files from setuptools/tests/bdist_wheel_testdata from being collected by pytest, but we couldn't yet figure out any working way to accomplish that.

[agronholm]

Should be a-ok now. The missing coverage lines reported by collateral/diffcov are due to conditional imports and would be covered by a combined coverage report.

[agronholm]

Adapted to changes in main, all good again.

Thanks Alex for the work here. I've added @agronholm as a Setuptools Developer. Please feel free to merge.
