Thanks for adding the extra info.

However, this doesn't explain why we now need the setuptools.build_meta
backend, we should say what upstream change caused this. This caused me
to look at the upstream v4.0.0 release notes and I found:

  - Rename Python package to roman-numerals on PyPI.
  - Publish roman-numerals-py as a meta-package that depends on
    roman-numerals and installs no modules.

So I'm not sure we can take the new version as-is, the roman-numerals-py
package is now empty.

It looks like this recipe is here to support python3-sphinx, have you
tested that still works after this update?

As a side note, when we upgrade a recipe across multiple upstream
versions we should include the changelog entries in our commit message
for each version we skip across, especially if there's a major version
bump in there as it's often because of some backwards incompatibility.

Best regards,

I'd clarify this a bit: either there's a complete changelog for each
in-between version, or no changelog at all. It can be tedious to
produce them, especially if there's a lot of recipes updates in a
patchset, and it's not a strict requirement.

You're right, it can be tedious. We need to be careful in cases like
this where an upgrade from v3.1 to v4.1 skips over a v4.0 major version
with significant things in the release notes.

Hi Liu,

Thanks for your patch.

Building btrf seems to be broken by this update:

Hi Mathieu
    I tryed to bitbake btrfs-tools to reproduce this error, But I can't reproduce it.

    Could share you local.conf with me?

Thanks
Liu

Note that the error happened in a 'qemux86-world-alt' build. You can
find the config for it here:
https://git.yoctoproject.org/yocto-autobuilder-helper/tree/config.json#n841

I'm fairly sure that the error (which is sphinx-related) is triggered
by this part:

DISTRO_FEATURES:append = ' api-documentation'
