Bug 916999 – [Future EAPI] Support for zstd compression in unpack

• Status: RESOLVED WONTFIX
• Product: Gentoo Hosted Projects

[Description Aidan Harris 2023-11-07 11:25:09 UTC]

I vendored go modules for an ebuild as .tar.zst and to my surprise Portage cannot unpack these.

Reproducible: Always

Unpack zstd files

I mostly plagarised the existing xz unpacking but had to alter the __unpack_tar function to resolve symlinks because for some reason this fails with an error that tar doesn't recognise the zstd format if I don't do this.

You want to use unpacker.eclass if you really need zstd compression.

This patch cannot be applied using git-am, so I am marking it as obsolete.

Support for new formats in unpack should be requested via a PMS update.

For this to land in PMS, large enough number of packages must actually need it.  Right now, I see two packages using '.zst' in ::gentoo, and none in ::guru.  In other words, zstd as a compressor used for file distribution is nowhere near popular right now.
