Subject: [bug#70132] [PATCH 05/11] channels: Autoload (git …) modules.
Date: Mon, 1 Apr 2024 22:25:17 +0200 [thread overview]
Message-ID: <b8b31c5056e8e01990e7ce22d1c07aaced22ec76.1712002698.git.ludo@gnu.org> (raw)
In-Reply-To: <cover.1712002698.git.ludo@gnu.org>
Autoloading Guile-Git is important in cases where (guix channels) is
used for little more than the <channel> definition. This is the case,
for example, of ‘guix describe’ or ‘guix shell’.
This reduces from 177 to 121 the number of .go files loaded when
running:
./pre-inst-env strace -e openat -o /tmp/log.strace \
guix describe -p /var/guix/profiles/per-user/$USER/current-guix
grep 'openat.*\.go.* = [0-9]' < /tmp/log.strace |wc -l
Likewise, it reduces the max RSS (as measured by ‘time -f %M guix
describe -p …’) from 54 to 37 MiB.
* guix/channels.scm: Autoload (git …) modules.
