  • [gentoo-dev] [PATCH 1/4] profiles/use.desc: create USE=strip global USE

    From Ionen Wolkens@21:1/5 to All on Fri May 26 06:10:01 2023
    Primarily intended for use by linux-mod-r1.eclass, which needs
    a global IUSE to control stripping of kernel modules *before*
    signatures and compression (alternative would be to simply never
    strip, but that seem sub-optimal).

    Originally meant to be USE=modules-strip or similar, but this can
    have a more general use case when portage does not know how to
    strip special files properly while the ebuild does.

    Notable is mingw ebuilds (wine-*, dxvk, vkd3d-proton, mingw64-*).
    If portage uses x86_64-pc-linux-strip on, e.g. mingw64-toolchain's
    runtime libraries, then at least the 32bit toolchain ends up broken
    and cannot compile anything anymore. But then dostrip -x results in
    unstripped files while we can use x86_64-w64-mingw32-strip in the
    ebuild potentially saving 60MB+. Currently this is done through
    USE=debug, but does not feel fully fitting given this isn't about
    adding debugging paths (or even symbols, or anything) and is merely
    "do not strip".

    No USE in ::gentoo currently contain the word "strip" and defining
    it should not conflict.

    This sounds fine (and a good idea), but we may want some indication
    in the USE flag description (eh), a QA policy to indicate
    it's only for special situations, or some note in the devmanual.

    Can see people getting this wrong and trying to use it in ebuilds
    which would work otherwise. But maybe the "special" in the USE
    description is enough?

    This is what I had in mind when I used that word. Didn't want the
    description to sound like it's aimed at developers more than users,
    but still have something that prevents matching common strip usage.
