[bug#63571] [PATCH v2 09/19] upstream: 'update-package-source' edits inp


From: Ludovic Courtès
Subject: [bug#63571] [PATCH v2 09/19] upstream: 'update-package-source' edits input fields.
Date: Mon, 29 May 2023 16:45:20 +0200

Previously, 'guix refresh r-ggplot2 -u' and similar commands would print
of list of input changes that would have to be made manually.  With this
change, 'guix refresh -u' takes care of updating input fields
automatically.

* guix/upstream.scm (update-package-inputs): New procedure.
(update-package-source): Call it when 'upstream-source-inputs' returns
true.
* guix/scripts/refresh.scm (update-package): Remove iteration over the
result of 'changed-inputs'.
* guix/import/test.scm (available-updates): Add support for input
lists.
* tests/guix-refresh.sh (GUIX_TEST_UPDATER_TARGETS): Add input list for
"the-test-package".
Make sure 'guix refresh -u' updates 'inputs' accordingly.
* doc/guix.texi (Invoking guix refresh): Mention it.
