[bug#27865] [PATCH 0/3] Use Guile-Git for 'guix pull'

[Ludovic Courtès]

Hello Guix!

This is the long-awaited change where ‘guix pull’ fetches code over Git
instead of stupidly grabbing a full snapshot generated on-the-fly by the
poor Savannah servers.

As a side-effect, ‘guix pull’ gains a ‘--commit’ and a ‘--branch’
option.  Also, ‘guix --version’ will now show a Git commit ID instead of
a date.

This change makes Guile-Git a hard dependency.  The transition might be
somewhat bumpy since it’s possible that users not having Guile-Git
installed will run ‘guix pull’ and, upon completion, will get an error
when they re-run ‘guix pull’.  This will be fixed by installing
‘guile-git’.  Thinking about it, (guix scripts pull) could perhaps try
to be smart and have an error message saying “please install Guile-Git”
or something.

Thoughts?

Another (minor) issue is that there hasn’t been an official release of
Guile-Git yet, and things are still changing a little bit.  However I
think most of the important things are in place.

Guile-Git currently lacks bindings for the progress-report API when
cloning the repo.  We’ll use it when it’s available.

Feedback welcome!

Thanks,
Ludo’.
