Full switch to poetry

[carmenbianca]

Accidentally closed #599 due to wrong branch name.

Fixes #467, fixes #289, fixes #587

I was doing some package maintenance for Fedora. This should make my life a whole lot easier.

Maybe postpone this for 2.0 major release. No longer a breaking change. Python 3.6 remains supported.

TODO:

• Translation build step.
• Don't install dev requirements in Docker images and reuse GitHub workflow
• Fix Docker containers
• Fix documentation
• Change log
• Write message to reuse mailing list
• Test poetry publishing
  • Signed releases?
• Fix python-debian dependency
  • Ideally, ship with dep5 parser microlibrary.
• Replicate and document make test / make lint.
• Fix pylint pre-commit.
• Remove requests dependency now that we're messing with dependencies anyway.

This is effectively ready for review. It all works without any breaking changes. The only thing I haven't tested is poetry publish.

[carmenbianca]

poetry publish tested. It works, with two caveats:

• Signing with GPG keys not possible.
• Because of our build.py step, the resulting wheel is not 'noarch'. This is incorrect, but I've not found a way to fix it. There probably will be a way to fix this once Poetry starts stabilising and documenting the build plugin system.

TODO: add runtime dependency on setuptools (pkg_resources)

I just tested the poetry install and poetry run reuse ... commands and it works well. For me this simplifies setting up a development environment. Thanks a lot!

Failing py3.11 test because of pytest-dev/pytest-cov#564

[carmenbianca]

I'm going to just merge this. Rebasing this branch frequently is rather time-consuming, and I've tested this thoroughly enough to know that it just works.

@carmenbianca Thanks! Sorry for not getting on this earlier.

[carmenbianca]

@linozen No worries! For the longest time, I maintained this project solo. Having more input is truly amazing, but by no means a blocker to keep the ball slowly moving :) Just let me know if I do something truly stupid.

This seems to break python -m build on Arch Linux.

[carmenbianca]

@grawlinson 1.1.0 was released yesterday. It changed the build system.

[grawlinson]

The build module is a PEP-517 compatible build backend that invokes the specified PEP-517 build method, and is what we use on Arch instead of the various PEP-517 tools (flit, poetry, etc).

Shall I open an issue?

[carmenbianca]

I see. Strange. Please open an issue.
