Issue

This seems to stem from a change #8544, while fixing deprecation there's a new added filter to tar extract that wasn't used before: https://github.com/python-poetry/poetry/pull/8544/files#diff-26f39fd2c1c2ff93b4e043ed53d6c9be8dd7c44328e15d0d238a068da199e171R281.

I've also verified its possible to install the same source package with pip on the same virtualenv:

poetry run pip install -v --force --no-binary ":all:" idna==3.4
Using pip 23.2.1 from /Users/USER/Library/Caches/pypoetry/virtualenvs/test-poetry-I-n-P1h1-py3.9/lib/python3.9/site-packages/pip (python 3.9)

[dimbleby]

that's what poetry is supposed to do, per https://packaging.python.org/en/latest/specifications/source-distribution-format/#unpacking-with-the-data-filter

you'll want to raise this with idna - or use their wheel distribution

[danni-m]

@dimbleby, since PEP-721 is only a few months old, can we get some grace time (at least with some configuration option)?
Even if we get a newer version of this package, it might only be compatible with some ecosystem packages people already use in the wild.

If this is acceptable, I can create a PR for this configuration flag.

[dimbleby]

I'd be against that but others might feel differently and their vote counts more.

The wheel installs fine, so you're not blocked (and I expect that's how almost everyone is installing idna anyway).

kjd/idna#129 (comment) suggests that there might be a new idna release in the not-too-distant future: so you're likely just as well off instead submitting a merge request there, to fix their sdist.

[Secrus]

Personally, I am against it. I don't like the idea of backing out of the already implemented way. The more "switches" and "toggles" we add, the more people will abuse this, and packages that don't comply with modern standards won't get fixed (and then break anyway once the grace period ends).

running in python:3.11-buster with poetry==1.7.0

[dimbleby]

Please report it to llama-cpp-python so that they can fix their sdist.

[dimbleby]

However I suspect the real issue is that python is wrong... python/cpython#107845

Probably something like pypa/build#675 (comment) would be accepted.

[cornel-masson]

Also experiencing this with ansible-base, fixed by downgrading poetry to 1.6. Will log an issue with ansible.

[dimbleby]

you are not using the latest poetry and you have not read the conclusion to the thread
