PyPI release cannot include parsl fork from github

poetry publish yields

Uploading fractal-server-0.3.0.tar.gz FAILED

HTTP Error 400: Invalid value for requires_dist. Error: Can't have direct dependency: 'parsl[monitoring] @ git+https://github.com/fractal-analytics-platform/parsl.git@1.3.1-dev' | [...]

This seems to be a fundamental problem with PEP440 and PyPI not accepting dependencies of this kind, see e.g.

• Support publishing git dependencies to PyPI using vendoring python-poetry/poetry#2828
• https://peps.python.org/pep-0440/#direct-references

For the time being, we'll switch to github releases (with attached binaries), so that installing the 0.3.1 version becomes

pip install https://github.com/fractal-analytics-platform/fractal-server/releases/download/0.3.1/fractal_server-0.3.1-py3-none-any.whl

Let's try to fix it in a cleaner way later on.

That's just for the server, right? Tasks & client can still be released to pypi?

Suboptimal of course, but good that we have this backup installation procedure until there is an actual fix.

That's just for the server, right?

Yes

[jacopo-exact]

need to check if pre-built packages hosted as github releases are allowed

[tcompa]

Currently obsolete, as we do not depend on parsl (fork) any more.
