Description Sam James archtester Gentoo Infrastructure gentoo-dev Security 2021-02-08 09:11:41 UTC
This is a popular Python library and losing it where we lack Rust is going to be problematic.

mgorny has already reported this upstream.
Comment 1 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2021-02-08 09:18:05 UTC
Technically speaking, this is an indirect dependency of everything, so this probably means removing Python entirely... which probably means removing arches entirely.
Comment 2 Ionen Wolkens gentoo-dev 2021-02-08 12:08:13 UTC
fwiw I have one Gentoo system without it (so no urllib3/requests either, it's not using gemato), but it's a very large affected subset nonetheless.
Comment 3 Joonas Niilola gentoo-dev 2021-02-09 07:11:49 UTC this should help a little bit.
Comment 4 Georgy Yakovlev archtester gentoo-dev 2021-06-03 18:10:29 UTC kinda solves it.
it's a snapshot version not released yet, but it's working and passing current tests.

    dev-python/cryptography: add 36.0.0, drop 3.4.7_p12052021 (Rust, unkeyworded)
    Unkeyworded while we figure out a plan to handle arches which currently
    do not support Rust.
    (We _might_ be able to handle some/all of them by building rust-bin bootstrap
    binaries ourselves, as Rust upstream handle some arches by giving them
    a lower tier of support w/o prebuilt Rust.
    Or we wait for the rustc + libgccjit backend. Or we wait for the GCC Rust frontend.)
