[bug#45774] [PATCH core-updates v2] build-systems/gnu: Allow unpacking/repacking more kind of files. |
|
Date: |
Wed, 13 Jan 2021 12:40:21 -0500 |
Before this change, only plain directories, tar or zip archives were supported
as the source of a package for the GNU build system; anything else would cause
the unpack phase to fail. Origins relying on snippets would suffer from the
same problem.
This change adds the support to use files of the following extensions: .gz,
.Z, .bz2, .lz, and .xz, even when they are not tarballs. Files of unknown
extensions are treated as uncompressed files and supported as well.
* guix/packages.scm (patch-and-repack): Only add the compressor utility to the
PATH when the file is compressed. Bind more inputs in the mlet, and use them
for decompressing single files. Adjust decompression and compression routines.
[decompression-type]: Return #f when no known compression extension is used.
[tarball?]: New nested procedure.
* guix/build/utils.scm (compressor, tarball?): New procedures. Move
%xz-parallel-args to the new 'compression helpers' section.
* tests/packages.scm: Add tests. Add missing copyright year for Jan.
* guix/build/gnu-build-system.scm (first-subdirectory): Return #f when no
sub-directory was found.
(unpack): Support more file types, including uncompressed plain files.
