[PATCH] guix: Improve download-nar. |
|
Date: |
Sat, 11 Mar 2023 20:11:52 +0000 |
Previously download-nar worked with gzipped nars and queried
berlin.guix.gnu.org (also known as ci.guix.gnu.org). ci.guix.gnu.org no longer
serves gzipped nars so this is of limited use.
This commit changes download-nar to query both the default substitute servers,
and queries for lzipped rather than gzipped nars, since those are available
from both.
* guix/build/download-nar.scm (urls-for-item): Return urls for lzip rather
than gzip compression, and from both default substitute servers. The comment
about CDN's is no longer relevant.
(restore-gzipped-nar): Rename to restore-lzipped-nar and reimplement
accordingly.
(download-nar): Add progress reporting and switch to use lzip rather than
gzip.
* guix/cvs-download.scm (cvs-fetch): Replace guile-zlib with guile-lzlib.
* guix/git-download.scm (git-fetch): Replace guile-zlib with guile-lzlib.
* guix/hg-download.scm (hg-fetch): Replace guile-zlib with guile-lzlib.
* guix/android-repo-download.scm (android-repo-fetch): Add guile-lzlib for
download-nar

Great :) I pushed this to master yesterday as
b59f89cf18fbad9ee95521c4cadc6642c580feb8.

Indeed, that should be easier now.
