Currently we are forced to use gunzip to make tar.gz archives.
gunzip
tar.gz
I'd like to use zstd because it's just better: notably, it's much faster. This can make a big difference in CI when syncing down packages.
zstd
I think if we are able to give flags like
--compressor=zstd
--compressor-extension=zst
The changes to code ought to be fairly minimal:
compressor
-I <compressor>
tar
tar.<compressor-extension>
gz
-z
Maybe instead of --compressor, multiple --tar-flag are much more flexible.
--compressor
--tar-flag
This approach relies on the compressor binary being installed and doesn't add any new dependency to cabal-cache itself.
cabal-cache
Apparently tar itself has some zstd support via the --zstd flag but at least on my system, but it's probably a much newer flag than just using -I.
--zstd
-I
