Reproduce:

from email.message import Message

from pathlib import Path

txt = Path('/users/denolf/dev/fabio/README.rst').read_text()

message = Message()
message.set_payload(txt)
_ = bytes(message)

[loichuder]

Funny. If it is a README parsing issue, why does it show only when using --pre 🤔 ?

[loichuder]

Btw, the culprit character is ø from the citation section: https://github.com/silx-kit/fabio?tab=readme-ov-file#citation

[woutdenolf]

When using --pre the message class is pyproject_metadata.RFC822Message and without --pre the message class is email.message.Message.

[woutdenolf]

I guess

pip install --pre fabio

Would be equivalent to

pip install -U --pre meson-python meson ninja cython
cython-3.0.11 meson-1.5.1 meson-python-0.16.0 ninja-1.11.1.1 packaging-24.0 pyproject-metadata-0.9.0b1 tomli-2.0.1

pip install --no-cache --pre fabio --no-build-isolation

pyproject-metadata-0.9.0b1 seems to be the problem (released today). With pyproject-metadata-0.8.0 it works fine and this is the one use when just doing pip install fabio.

[woutdenolf]

pypa/pyproject-metadata#149

[woutdenolf]

Reproduce for python>3.7

pip install --pre fabio --no-cache --no-binary fabio

[kif]

Why can't I just say we don't support python 3.7 anymore ?

[woutdenolf]

You can of course but it won't fix the bug in pyproject-metadata. You can close this issue in fact. It has nothing to do with fabio.

[woutdenolf]

Fixed upstream (pyproject-metadata 0.9.0b3)
