Hello,

Here's another batch of changes to Python eclasses. This time it
includes four changes:

1. Fix for DISTUTILS_UPSTREAM_PEP517 when ebuild locally overrides
DISTUTILS_USE_PEP517. This is a rare case, see the last two commits
for the workarounds that will no longer be necessary.

2. Bumping dev-python/setuptools dep. Long story short, upstream
introduced support for new license syntax in setuptools 77,
and immediately started scaring people with deprecation warnings
for the old syntax, so we have a growing number of projects
requiring >=77. The new version will be ready to go stable
on Saturday.

3. Removing the use of dev-python/unittest-or-fail. It was an unittest
wrapper for Python < 3.12, to make test phase fail if there were
no tests (e.g. distutils_enable_tests call was wrong, or upstream
suddenly moved tests on version bump). It is no longer needed for
Python 3.12+, and since we can reasonably expect people to always
test with 3.12+, this should catch any mistakes and we do not need
to go through extra hoops for 3.11.

4. Add verbose deprecation warnings for `distutils_enable_tests
setup.py`, and for non-PEP517 builds. These are rather ugly as they
appear during dependency calculation (hence they need the package
name explicitly printed). Good news is, the use is almost gone
from ::gentoo, so they are specifically targeted at overlays.

Remove the use of dev-python/unittest-or-fail in favor of using stdlib
unittest runner for all implementations. While technically the latter
doesn't error out on "no tests" on Python 3.11 and older, this doesn't
really matter, because we're going to detect broken invocations while
testing on 3.12+.

Hi Michał,

Does this mean further deprecations to setup.py support are coming
soon? system76-driver's build process uses setup.py and hasn't seen
any changes yet to work toward PEP517, so I am wondering how soon
that's going to be a problem.

Thanks,
Bryan

Ebuilds without DISTUTILS_USE_PEP517 are deprecated for a long time
already, and we will be removing the support entirely soon. However,
calling esetup.py within PEP517 ebuilds will continue to work until
setuptools upstream breaks it.

Perfect, I was hoping esetup.py would continue to work. Thanks for the
quick response.
