numpy-1.26.4 (Python module)

[Bruce Dubbs]

New point version.

[Douglas R. Reno]

This package doesn't seem to build without some upgrades:

renodr [ /sources/numpy-1.26.4 ]$ pip3 wheel -w dist --no-build-isolation --no-deps --no-cache-dir -Csetup-args=-Dallow-noblas=true $PWD

  note: This error originates from a subprocess, and is likely not a problem with pip.

Looking upstream it looks like they removed their bundled copy of meson_python, and now depend on meson_python-0.15.0 explicitly (see ​https://github.com/numpy/numpy/pull/25748)

However, meson_python-0.15.0 now requires an update to pyproject-metadata as well - pyproject-metadata-0.7.1. I'll file tickets for both of those

After upgrading both pyproject-metadata and meson_python, the build succeeds. However, the tests throw up an error:

... and then immediately abort. This seems to be ​https://github.com/numpy/numpy/pull/25645

To fix this, we'll need to update pytz. I've installed pytz-2024.1 (we should add that as a dependency too) and after installing it and running the tests again, they now behave... mostly normal.

I'm on my test machine, so no gfortran is present. Because no gfortran is present three test failures occur, but otherwise it builds, installs, and mostly tests fine now.
