Subject: [PATCH 0/5] Download the Guile bootstrap tarball via a derivation
Date: Thu, 27 Jul 2017 16:52:50 +0200

Hello,

In Nov. 2016 we added the "download" built-in builder, meaning that the
daemon can perform downloads on behalf of clients:

  https://bugs.gnu.org/22774

This patch series is a followup:

  1. It removes backward-compatibility code in (guix download), thereby
     assuming guix-daemon supports the "download" built-in builder.

  2. It downloads the Guile bootstrap tarball via a fixed-output
     derivation, and thus removes the Makefile targets that were
     responsible for downloading this until now.

With this change, bootstrapping is somewhat simplified since now
(almost) everything is a derivation.  The Guile bootstrap tarballs for
the supported architectures no longer need to be installed, which saves
14 MiB on the installed ‘guix’ package:

After that we still have a few statically-linked binaries in
gnu/packages/bootstrap.  Perhaps we’ll remove them eventually by adding
an “extract” builder or similar.

These patches are for the next ‘core-updates’.

Ludo’.

Ludovic Courtès (5):
  download: Assume the "download" built-in builder is available.
  gnu: guile-bootstrap: Use a fixed-output derivation to download.
  gnu: bootstrap: Prefer HTTPS for downloads.
  build: Remove code to download the Guile bootstrap tarball.
  gnu: guix: Factorize downloads of bootstrap tarball.
