I'd like to see this change land in F28! Anyway, I think there is a showstopper: * Fedora Packaging guidelines demand packages bundle no dependencies (e.g. libraries, or in Rust's case crates). This is a good choice in my opinion. * Rust currently has no ABI definition compatible over different versions of the rust compiler. As a result, every time a new compiler is released it will also require *ALL* rust packages to be rebuild. See https://github.com/rust-lang/rfcs/issues/600 for details and discussion. * To get a sane update strategy, it is critical that not too much packages are involved in rebuilds. Consider a CVE in openssl: Luckily we can rebuild openssl (plus its subpackages) and ship it. No need to rebuild every application that uses openssl or uses another package which uses openssl.
As far as I understand, these 3 points are conflicting right now. Either Rust gets an ABI or we need to give up one of the other two principles, which I highly recommend not to do. Disclaimer: I'm no Rust expert, nor am I an ABI expert, so I might be completely wrong about this. _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org
