Subject: python: run isort on everything
X-Git-Url: http://git.efficios.com/?p=babeltrace.git;a=commitdiff_plain;h=5995b304e5601bf9b97ffa661b21874bec6c0e3a

python: run isort on everything

Run isort on the whole repo, to nicely sort Python imports.

Add a mention in CONTRIBUTING.adoc, that all Python imports must be
sorted using the version of isort specified in dev-requirements.txt.

Add `isort ~= 5.12` to dev-requirements.txt.  5.12 is the latest stable
version available on PyPi as of writing.

Tell isort to use its `black` profile, in pyproject.toml, so that
black remains happy.  The details of that profile are here:

  https://pycqa.github.io/isort/docs/configuration/profiles.html

Tell isort to ignore `tests/utils/python/tap`, since it's code copied
from elsewhere.

Use the `length_sort` option, because Philippe prefers it like that.
See:

  https://pycqa.github.io/isort/docs/configuration/custom_sections_and_ordering.html
