From 00376d1345475fb3613a0d58584f161cd870ea90 Mon Sep 17 00:00:00 2001 From: John Snow <jsnow@redhat.com> Date: Tue, 29 Jun 2021 17:43:09 -0400 Subject: [PATCH 01/15] python/qom: Do not use 'err' name at module scope Pylint updated to 2.9.0 upstream, adding new warnings for things that re-use the 'err' variable. Luckily, this only breaks the python-check-tox job, which is allowed to fail as a warning.

Let's use pipenv to test the oldest versions we claim to support. This matches the stylistic choice to have pipenv always test our oldest supported Python version, 3.6. The effect of this is that the python-check-pipenv CI job on gitlab will now test against much older versions of these linters, which will help highlight incompatible changes that might otherwise go unnoticed. Update instructions for adding and bumping versions in setup.cfg. The reason for deleting the line that gets added to Pipfile is largely just to avoid having the version minimums specified in multiple places in config checked into the tree. (This patch was written by deleting Pipfile and Pipfile.lock, then explicitly installing each dependency manually at a specific version. Then, I restored the prior Pipfile and re-ran `pipenv lock --dev --keep-outdated` to re-add the qemu dependency back to the pipenv environment while keeping the "old" packages. It's annoying, yes, but I think the improvement to test coverage is worthwhile.)

It's still the test I'd most prefer you to run, but it's not the test you are most likely to be able to run.

For instance, this stub file will cause "pip install --user -e ." to fail in spectacular fashion with misleading errors. "pip install -e ." works okay, but for some reason pip does not support editable installs to the user directory when using PEP517. References: https://github.com/pypa/pip/pull/9990 https://github.com/pypa/pip/issues/7953 As outlined in ea1213b7ccc, it is still too early for us to consider moving to a PEP-517 exclusive package. We must support older distributions, so squash the annoyance for now. (Python 3.6 shipped Dec 2016, PEP517 support showed up in pip sometime in 2019 or so.) Add 'pyproject.toml' to the 'make clean' target, and also delete it after every pipenv invocation issued by the Makefile.

It *doesn't* fix the formatting to make it look pretty or reasonable in generated output. It *does* fix a few small instances where Sphinx would emit a build warning because of malformed ReST -- If we built our Python docs with Sphinx.
