The patch adds lzip support to the ports framework. I tested
"EXTRACT_SUFX = .tar.lz" with some ports and everything works without
problems.
In the past we've held off on diffs like this (e.g. for xz) until
it was actually used by a number of ports, I haven't really run into
it in the wild, do you know of any software distributed using lzip?
Yes, some GNU and Savannah projects:
rsync --list-only -r rsync://ftp.gnu.org/gnu | grep '\.lz$'
rsync --list-only -r rsync://dl.sv.nongnu.org:/releases | grep '\.lz$'
Graphicsmagick and imagemagick also have tarballs compressed with lzip.
GraphicsMagick and ImageMagick provide XY compressed archives.
They provide tarballs compressed with gz, bzip2, xz and lzip.
ImageMagick also use 7zip and zip. Basically they use everything :)
The GNU project has standardized on using XZ.
Do you have any document or link about that?. IIRC, GNU doesn't have
preference by any file compressor, except obviously gzip.
https://www.gnu.org/prep/ftp.html :
"Various compression formats are used on the server: .gz is gzip; .bz2
is bzip2; .xz is xz; .lz is lzip."
Automake, GNU tar and texinfo support the lzip format.
<rant>I guess the xz format is more used because this is the sucessor of
the original lzma-utils (that was an horrible file format despite of the
good compression algorithm).</rant>
Is there anything else?
I've not found more projects using lzip. Anyway, the commits are done.
The point wasn't whether projects provide more than one format or
whether there is overlap between lzip/xz. It's to point out projects
that provide say gzip and lzip archivers or only lzip archives. I don't
have a problem adding more formats, but there should be real purpose for
doing so and I haven't seen that so far.
