Please make sure the package builds successfully at least for Fedora Rawhide.

- If the build failed for unrelated reasons (e.g. temporary network
  unavailability), please ignore it.

Comment 2 Zbigniew Jędrzejewski-Szmek 2026-07-30 21:04:03 UTC

The rust-liblzma-sys dependency was built in rawhide, so this should build now too.

scratch build: https://koji.fedoraproject.org/koji/taskinfo?taskID=148491225

Please see my comments on the liblzma-sys review:
https://bugzilla.redhat.com/show_bug.cgi?id=2494237#c19

We need this crate (eventually) to work on i686 since we need it for newer versions of rust-async-compression, and it is still needed on i686.

First review pass:

- Update to latest version (this is for 0.4.7, latest is 0.4.8).
- Drop ExcludeArch, we need this on i686 *and* it's the wrong way to exclude arches for library-only Rust crates (use the "package.unsupported-arches" setting instead).
