Improve debug logging for "Skipping wheel xxx-7.7.2-cp310-cp310-manylinux_2_35_x86_64.whl as this is not supported by the current environment"

[alexanderilyin]

Issue Kind

Change in current behaviour

Description

There is partcad package which depends on cadquery-ocp. Wheels for which are provided by:

• https://github.com/CadQuery/ocp-build-system

And poetry ignores compatible wheel which has platform specified as manylinux

Give the following configuration:

[tool.poetry.dependencies]
cadquery-ocp = { version = "^7.7.2" }

poetry install will fail: output.txt.

When it's running on:

⬢ [Docker] ❯ python -c "import sys; print(sys.platform)"
linux

⬢ [Docker] ❯ lsb_release -d
Description:    Debian GNU/Linux 11 (bullseye)

According to the following:

• https://github.com/pypa/manylinux

cadquery_ocp-7.7.2-cp310-cp310-manylinux_2_35_x86_64.whl should be selected but in reality it's not supported by the current environment

Impact

It will allow to use Poetry with packages which are distributed for manylinux platform.

Workarounds

Override sys_platform using markers:

[tool.poetry.dependencies]
python = "^3.10"
partcad = { version = "^0.7.16", markers = "sys_platform == 'manylinux'" }

[alexanderilyin]

Well, it's something else:

Package has cp310-cp310-manylinux_2_35_x86_64 tag but closest tag supported by Poetry is cp310-cp310-manylinux_2_31_x86_64.

Probably next step for me is to figure out what does 35 and 31 mean.

[alexanderilyin]

Okay, it's actually 2_35 vs 2_31 which are glibc versions, and here is what I have:

⬢ [Docker] ❯ ldd --version
ldd (Debian GLIBC 2.31-13+deb11u11) 2.31

[alexanderilyin]

It seems that in my case solution was to move from bullseye to bookworm:

⬢ [Docker] ❯ lsb_release -d
No LSB modules are available.
Description:    Debian GNU/Linux 12 (bookworm)

⬢ [Docker] ❯ ldd --version
ldd (Debian GLIBC 2.36-9+deb12u8) 2.36

I'd keep this issue open but repurpose it to improve debug logging in is_supported_by_environment() so It would tell that my glibc is too old.

[alexanderilyin]

I think some kind of fuzzy search or levenshtein distance would allow to filter supported tag and then do some additional parsing / explanation.

[dimbleby]

code is here, if you have improvements to the logging please submit a merge request

though I'd hint that if you are getting into "fuzzy search or levenshtein distance" then you are likely over-complicating it

[alexanderilyin]

Will do thanks!
