Subject: [bug#65866] [PATCH v2 7/8] git-download: Use “builtin:git-download” when available.
Date: Sat, 23 Sep 2023 00:28:03 +0200 [thread overview]
Message-ID: <b0a3a92d6adda6582cd3aa61d3be30a90d91c96b.1695421391.git.ludo@gnu.org> (raw)
In-Reply-To: <cover.1695421391.git.ludo@gnu.org>
Fixes <https://issues.guix.gnu.org/63331>.
Longer-term this will remove Git from the derivation graph when its sole
use is to perform a checkout for a fixed-output derivation, thereby
breaking dependency cycles that can arise in these situations.
* guix/git-download.scm (git-fetch): Rename to…
(git-fetch/in-band): … this. Deal with GIT or GUILE being #f.
(git-fetch/built-in, built-in-builders*, git-fetch): New procedures.
* tests/builders.scm ("git-fetch, file URI"): New test.
