Subject: dh-python: Deps guarded by (python3 << 3.X) break python-3.(X-1) use

Date: Fri, 13 Jan 2023 15:02:11 +0100

Package: dh-python
Version: 5.20221001
Severity: normal
X-Debbugs-Cc: schopin@ubuntu.com

For instance, pylint has "tomli>=1.1.0;python_version<'3.11'" in its
pyproject.toml, which is translated as "python3-tomli (>= 1.1.0) |
python3 (>= 3.11)".

This means that if we have python == 3.11 but still have python3.10 in
the archive, any code that iterates over all supported archive risks
failing simply due to the tomli module missing.

This is currently happening in the distro-info autopkgtests for the
python3-defaults migration from unstable to testing (and also in
Ubuntu). I'll probably be adding tomli as a test dependency in Ubuntu as
a stopgap, but I figured someone might think of a better long-term
solution to the issue.

Yes, I was aware of this risk when I implemented it, but it was the best
I could do with the knobs available.

python3-defaults now provides virtual packages that we can use to more
accurately model supported releases here:
https://salsa.debian.org/cpython-team/python3-defaults/-/merge_requests/13
It should land in bookworm. So trixie should be able to make full use of
them.

For now, you should explicitly add extra dependencies, when necessary,
and remove them later.

Closes: 1028603 1043301
Changes:
 dh-python (6.20230813) unstable; urgency=medium
 .
   * When we build a wheel for tox, with the distutils plugin, make sure
     our .pydistutils.cfg isn't present, so we build it in the standard layout.
   * Remove RECORD files from dist-info, these are incompatible with
     multi-arch.
   * Support for backporting the pyproject plugin to Python < 3.11. Thanks
     Stuart Prescott. (Closes: #1043301)
   * Use values for _PYTHON_HOST_PLATFORM that are closer to Python's defaults.
   * tox: Pass -x testenv.passenv+=_PYTHON_HOST_PLATFORM, so that pip will
     accept the _PYTHON_HOST_PLATFORM that the test wheel was built with.
   * Generate dependencies on using python3-supported-min and
     python3-supported-max.  Allowing dependencies to work correctly on all
     supported python 3 versions.  (Closes: #1028603)
   * pybuild-auto-pkgtest: Run tox tests against the installed package.
