Hello,

These two patches update Disarchive to 0.4.0.  This version of Disarchive has
support for XZ, which requires Guile-LZMA.  Since Disarchive is a dependency
of the Guix package, I’m hoping someone else can look over the patches before
I push them.

I made sure to check the following things:

  • Building the Guix package
  • Running ‘guix pull’
  • Recovering a GZip-compressed tarball from Guix
  • Recovering a XZ-compressed tarball from Guix
  • Cross-compiling Guile-LZMA, Disarchive, and Guix itself
  • Running Guix from a cross-built Hurd image

I couldn’t use Disarchive recovery from the Hurd, but I’m inclined to
assume that it’s not a regression [1].  Other than that, everything seemed
okay to me.

If you want to test recovering an XZ source, you can use (amusingly)
the ‘gzip’ package source code (as of writing it’s the only XZ spec
available).  You need to run the Guix daemon in an environment that
provides the new Disarchive and Guile-LZMA (I used ‘./pre-inst-env
guix shell -D guix’).  Then, you can run

  $ GUIX_DOWNLOAD_FALLBACK_TEST=disarchive-mirrors \
        ./pre-inst-env guix build --check -S gzip

Thanks in advance!

[1]: AFAICS, it fails when the SWH downloader tries to pipe the tarball
it’s downloading into ‘tar’ to extract it.
