Virtualenv: [regression] When there's `setup.cfg` with `attr:` in CWD, `pip install` crashes under virtualenv 20+

Issue

$sbj. Possibly related to https://github.com/pypa/virtualenv/issues/1670.
Reproducible under Python 2 specifically, doesn't seem to affect py3.

Repro

  1. Create setup.cfg in CWD
$ cat setup.cfg 
[metadata]
name = boom
version = attr: boom.versiontools.get_self_version

2.

python2 -m pip install 'virtualenv >= 20'
python2 -m virtualenv test-venv-py2
  1. DON'T CHDIR ELSEWHERE
  2. Install some existing package there:
test-venv-py2/bin/pip install setuptools

(not necessarily setuptools, could be pip, six, anything really, but has to exist on PyPI)

  1. Observe an ImportError because it loads the config from CWD which in turn tries to import boom.versiontools.get_self_version:
$ test-venv-py2/bin/pip install setuptools
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support
Requirement already satisfied: setuptools in ~/src/github/experiments/boom/test-venv-py2/lib/python2.7/site-packages (44.0.0)

  • OS: Gentoo Linux (also reproducible under centos:7 docker container)

  • pip list of the host python where virtualenv is installed:

    $ python2 -m pip list

Observe an ImportError because it loads the config from CWD which in turn tries to import boom.versiontools.get_self_version

Isn't that what it should do? What should happen here in your expectation?

gaborbernat picture gaborbernat on 4 Mar 2020

It doesn't try to import things under Python 3 / Python 2 + virtualenv 16. But under Python 2 + virtualenv 20 it explodes.

webknjaz picture webknjaz on 4 Mar 2020

And no, it shouldn't explode when you're installing other packages just because you have something in CWD.

webknjaz picture webknjaz on 4 Mar 2020

@webknjaz are you 100% that it does not import on old virtualenv? (maybe it just fails on 20+) - it's a setuptools internal implementation detail

gaborbernat picture gaborbernat on 4 Mar 2020

Positive. It fails on virtualenv 20+ but only combined with Python 2, that's what I'm saying.

webknjaz picture webknjaz on 4 Mar 2020

https://github.com/pypa/virtualenv/pull/1688 will likely fix it, can you check?

gaborbernat picture gaborbernat on 4 Mar 2020

Okay, I'll check.
