Tox: virtualenv creates incorrect/broken python3 interpreters

[RonnyPfannschmidt]

as far as i can tell all released versions of virtualenv create a python interpreter with a broken venv module

it would be helpful if python3 interpreters would always use their respective venv module,
making the virtualenv code path something for only the legacy/dead python interpreters

currently i'm working around the issue by using tox-venv

virtualenv rewrite will do this which we'll switch to soon after 👍 I don't think your statement holds true generally though.

[RonnyPfannschmidt]

most things dont "break", but edge details like the venv module break for example

[RonnyPfannschmidt]

btw, whats the timeline for the rewrite? i recall that the rewrite branch of virtualenv is unfinished since ages now

[gaborbernat]

I hope by September, the thing is to test the new virtualenv I need a rewrite of tox first 😅 which is wip, but might park and finish first the rewrite 😎 of that

@RonnyPfannschmidt if you're looking for a workaround, there's prior art in https://github.com/pre-commit/pre-commit/blob/376d283ba38a24a0df0dff8463f8474d1fd8e3d2/pre_commit/languages/python_venv.py#L21-L47

I think this issue is maybe on the wrong project though and should be on pypa/virtualenv instead?

Stopping to use virtualenv is hardly a issue that makes sense on virtualenv

[asottile]

@RonnyPfannschmidt but the core issue is "venv from virtualenv is broken" is it not -- that's kinda unrelated to tox

[RonnyPfannschmidt]

@asottile this is about tox using virtualeenv instead of venv for python3, this is not about virtualenv itself

@gaborbernat as far as i understood this one will auto-close with the next gen virtualenv once it lands?

[asottile]

tox will continue to use virtualenv even when that lands, just the internal mechanisms of virtualenv will change approach for py3

@RonnyPfannschmidt. If you need to use venv for Python 3, there is tox-venv, which was born out of #630.

@rpkilby thanks for the reference, i am currently using tox-venv to avoid tox breaking the world
