[PATCH 00/11] Improve startup time and memory footprint for short-lived commands |
|

Hello!
This is a pretty boring series adding #:autoload in strategic places.
The goal is to avoid loading tons of modules and shared objects when
running ‘guix describe’ or ‘guix shell’ on a cache hit.
There’s a tiny bit of reshuffling to make that easier:
• Bits moved from (guix channels) to (guix git);
• ‘call-with-temporary-output-file’ no longer re-exported by
(guix utils).
I measured the impact with things like:
strace -e openat -o /tmp/log.strace guix describe
grep 'openat.*\.go' </tmp/log.strace | wc -l
and also checking specifically whether things like Guile-Git,
Guile-Gcrypt, and Guile-GnuTLS were being loaded.
Feedback welcome!

Ludovic Courtès (11):
channels: Use SRFI-71 instead of SRFI-11.
git: Add ‘repository-info’ and use it in (guix channels).
channels: Move ‘commit-short-id’ to (guix git).
git: Add ‘tag->commit’ and use it in (guix channels).
channels: Autoload (git …) modules.
guix system: Autoload some more.
utils: Don’t re-export ‘call-with-temporary-output-file’.
guix: Delay loading of (gnutls).
ui: Delay use of (guix build syscalls).
Autoload (guix build syscalls).
Autoload (gcrypt hash).
