Hello Pythonistas,

I've built pyproject-rpm-macros-1.8.0-1.fc39 in Rawhide and updates are available for older Fedoras. Later on I plan to sync this to c9s as well.

https://bodhi.fedoraproject.org/updates/pyproject-rpm-macros

The release brings a bugfix/enhancement (depending on how you look at it) and a deprecation.

## %pyproject_buildrequires now supports self-referential extras requirements

That is, if you package e.g. attrs and use:

%pyproject_buildrequires -x tests

It correctly handles the requirement on attrs[tests-no-zope] as defined here:

https://github.com/python-attrs/attrs/blob/23.1.0/pyproject.toml#L45

When a self-referential dependency on extras is found, the required extra is added to the list of desired extras, and all the previously discarded "alien" requirements are reevaluated using the new extras list.

Example use: https://src.fedoraproject.org/rpms/python-fiona/pull-request/2

## The provisional %{pyproject_build_lib} macro was deprecated

There is no scheduled removal, but it may break entirely in the future.

See https://lists.fedoraproject.org/archives/list/python-devel@lists.fedoraproje... for motivation.

Packagers are encouraged to use $PWD/build/lib.%{python3_platform}-cpython-%{python3_version_nodots} instead if they need to (works on all current Fedoras but not on RHEL 9's Python 3.9).

The following Fedora Rawhide packages use it:
