time-machine: Make target commit check cheaper.
Commit 79ec651a286c71a3d4c72be33a1f80e76a560031 introduced a check to
error out when attempting to use ‘time-machine’ to travel to a commit
before ‘v1.0.0’.
This commit fixes a performance issue with the strategy used in
79ec651a286c71a3d4c72be33a1f80e76a560031 (the repository was opened,
updated, and traversed a second time by ‘validate-guix-channel’) as well
as a user interface issue (“Updating channel” messages would be printed
too late).
This patch reimplements the check in terms of the existing #:validate-pull
mechanism, which is designed to avoid extra repository operations.
Fixes <https://issues.guix.gnu.org/65788>.
* guix/inferior.scm (cached-channel-instance): Change default value
of #:validate-channels. Remove call to VALIDATE-CHANNELS; pass it
as #:validate-pull to ‘latest-channel-instances’.
* guix/scripts/time-machine.scm (%reference-channels): New variable.
(validate-guix-channel): New procedure, written as a simplification of…
(guix-time-machine)[validate-guix-channel]: … this. Remove.
Pass #:reference-channels to ‘cached-channel-instance’.
