Compatibility problem with Python 3.9?

Compatibility problem with Python 3.9?

[msiemens]

Interesting. I suspect this is more due to a Git update than caused by the Python upgrade. I use Python 3.8 locally and tests started to fail for me too. I'll look into this…

[msiemens]

Seems like this is related to gitpython-developers/GitPython#1014 which in turn is caused by git/git@d18c950 which was published in Git v2.27.0. The issue has been fixed in GitPython v3.1.3 but we're using GitPython 2.x. Updating to GitPython 3.x means dropping Python 2 support. So I'll publish a release that drops Python 2 support in order to fix this issue.

[mhjacks]

Thank you! That will work well for us as we don't support Python 2 in Fedora anymore.

[msiemens]

Should be fixed with v2.0.0 🙃

[mhjacks]

I don't see setup.py in the new release tarball?

[msiemens]

Oh, weird. I forgot to publish the release to PyPI. The release there should contain the setup.py. I switched the build to Poetry which generates the setup.py when building the release artifacts.

[mhjacks]

Ah, that makes sense. Thanks! I was unaware that Poetry did that. I'll work on packaging 2.0.0 for Fedora.

[mhjacks]

OK, I'm working on packaging, and I've run a super-minor test problem (init.py in tests/ doesn't seem to have import os and the test suite complains about that). But there's also this:

% nosetests-3

Is this another case of "the output changed" or is it something more significant?

[msiemens]

That's strange. Seems like this is the exact issue that you had at the start. Could you post the output of running python -c 'import git; print(git.__version__)' in your build environment where PyGitUp is installed?

[mhjacks]

% python -c 'import git; print(git.__version__)'
3.0.9

Which is interesting, because the package claims to be 3.1.0:
python3-GitPython-3.1.0-3.fc33.noarch

Clearly the package is installing 3.0.9 though:

It appears we're past the initially reported issue, so I'm ready to close this (Fedora mislabeling a package version isn't really your problem). I see you also loosened the dependency on colorama. Thanks! Would you please consider adding the import os to the test suite as well?

[msiemens]

Would you please consider adding the import os to the test suite as well?

Where is it missing? As far as I can tell, the tests run without errors

[mhjacks]

When I run nosetests on f32

I get this error:

FAILED (errors=1)

I do not see an import os in this file:
https://github.com/msiemens/PyGitUp/blob/master/PyGitUp/tests/__init__.py so I suspect that's why I'm seeing this error. I could be wrong, though.

[msiemens]

Funny! Since PyGitUp 2.0 I switched to PyTest for running the tests and there everything runs fine. But running with nosetests throws an exception as in your example. I'll publish a post-release with a fix

[msiemens]

This should be fixed now with v2.0.1.post1

[mhjacks]

Excellent! Thanks.
