Description Dora O’Fee 2023-06-20 12:36:38 UTC

Could you please explain the reason for removing jemalloc dependency in the package, and document it explicitly in the spec file? Many thanks!

The performance improvements using jemalloc seem to apply to Fedora/RHEL too: https://github.com/sharkdp/fd/pull/481#issuecomment-534494592.

Comment 1 Fabio Valentini 2023-06-22 15:20:46 UTC

As far as I can tell, there are still some reasons that prevent us from using jemalloc:

- The jemalloc-sys crate would need adaptations to build against system libjemalloc instead of the bundled copy
- The jemallocator crate does not seem to work / support targets other than x86_64-unknown-linux-gnu. We need support for i686, aarch64, s390x, and ppc64le as well.

I'll document this in the spec file for fd-find.
