bug#28709: [PATCH 0/4] Content-addressed mirrors for VCS checkouts

["Ludovic Courtès" <ludo@gnu.org>]

Hello,

Here’s a ready-to-merge patch series.  Once applied, nars
(aka. “substitutes”) are downloaded and extracted when a VCS checkout
fails.  This will address cases such as the recent Guile-Git repository
renaming for people who have disabled substitutes.

I’m Cc’ing 宋文武 because this also moves the progress-report code to
a new (guix progress) module.

Feedback welcome!

Ludo’.

  download: Remove old-Guile leftovers.
  download: Make 'http-fetch' public.
  Add (guix progress).
  download: Download a nar when a VCS checkout fails.
