[Pkg-mc-devel] Bug#893389: mc: please add .tar.zst / .tzst support

[Adam Borowski]

Package: mc
Version: 3:4.8.20-1
Severity: wishlist

Hi!
ZSTD support has just been merged into tar's upstream git.  The extensions
are .tar.zst and .tzst, just the same as for any other of umpteen compression
algorithms tar supports.

As Midnight Commander's release cadence isn't very frequent, it'd be good to
add this soonish -- as I see, a change done today would be just likely to make
it to Buster.  And, invoking a too old version of tar is no different than any
other helper that's not installed.

Besides upstream git, you can get tar with backported zstd support at
https://angband.pl/debian/pool/main/t/tar/ (amd64,i386: jessie, armhf:
stretch, arm64,x32: unstable).

ZSTD is an awesome compressor, that thrashes competition along the
speed:ratio envelope all the way from LZO to low-level XZ.  Especially gzip
and bzip2 have no reason to exist other than for old compat purposes.


Meow!
