Bug 717746 – dev-python/numpy and dev-python/numpy-python2: consider removing PKG-INFO to force cython compilation

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Pacho Ramos 2020-04-16 19:16:36 UTC]

When I was reviewing how other distributions where packaging numpy* packages I found that Fedora and openSuSE are doing:
rm -v PKG-INFO

That way they force cython run due to this in setup.py
    if run_build:
        from numpy.distutils.core import setup
        cwd = os.path.abspath(os.path.dirname(__file__))
        if not os.path.exists(os.path.join(cwd, 'PKG-INFO')):
            # Generate Cython sources, unless building from source release
            generate_cython()

        metadata['configuration'] = configuration


I am unsure if we are not doing it on purpose... but, for letting you know before I forget about it :)

I think running cython would only be necessary if we actually patched the numpy source code. Otherwise, it's a waste of CPU time.

Fine, thanks a lot :)
