Fix pypy3 tests

[BeyondEvil]

No clue why pypy is failing. Opened a ticket here

[RonnyPfannschmidt]

@BeyondEvil compount issue with tox and setuptools_scm

when tox tries to find the version, it gets warning output from setuptools_scm as well

@gaborbernat any idea what this could be ?

@BeyondEvil a workaround may be to unshallow the checkout and/or ensure its filtered instead of completely shallow

[RonnyPfannschmidt]

FTR; as far as i can tell setuptools_scm warning output lands on the stdout instead of the stderr, this could indicate a pypy bug

A small reproducer would be helpful

There is an error when running tox deep inside pytest (this one is from the Ubuntu run). Why should that be on stdout?

python -m tox -e pypy3-cov
  shell: /bin/bash -e {0}
  env:
    pythonLocation: /opt/hostedtoolcache/PyPy/3.8.12/x64/bin

If I run pip install of these packages it succeeds:

I don't know.

I'll try to create a small repro repo later.

I tried to reproduce locally, following the commands in the runner log (from Ubuntu)

cd /tmp
wget https://downloads.python.org/pypy/pypy3.8-v7.3.7-linux64.tar.bz2
tar -xf pypy3.8-v7.3.7-linux64.tar.bz2
pypy3.8-v7.3.7-linux64/bin/python -m ensurepip
pypy3.8-v7.3.7-linux64/bin/python -m pip install --upgrade tox
git clone https://github.com/pytest-dev/pytest-html.git
cd pytest-html
../pypy3.8-v7.3.7-linux64/bin/python -m tox -e pypy3-cov

Tests run and pass.

Ok, that's good to know.

I'm working on a repro repo.

Maybe I'm just stupid and/or it's a total red herring, but if I remove pyproject.toml from the repro repo that I'm setting up I get an error that I can't figure out why I'm getting. As far as I can tell, there is no reference to it from a GHA or tox perspective.

https://github.com/BeyondEvil/pypy3-error-repro/runs/4844352587?check_suite_focus=true

So, maybe the issue is related to it somehow? Maybe something to do with setuptools?

Wait... could this be related:

[tool.setuptools_scm]
local_scheme = "no-local-version"
write_to = "src/pytest_html/__version.py"

I still don't get why it breaks if the file is missing completely...

I guess crisis averted, seems like today Tox relies on pyproject.toml being present.

[BeyondEvil]

@RonnyPfannschmidt What are the potential drawbacks of switching the plugin to pyproject.toml instead?

At the very least do what we do in https://github.com/pytest-dev/pytest-selenium?

[BeyondEvil]

Not sure how relevant this is anymore. Closing.

Feel free to reopen if I'm wrong.

[mattip]

We have weekly CI runs of PyPy + pytest-html to make sure it keeps working. Since the tests are green, I think it is fine to close.
