When computing channel instance derivations.
This is useful when you want to generate compatible derivations that can be
run with a daemon that potentially doesn't support builtin builders that the
daemon you're using to generate the derivations has.
I'm looking at this in particular because I want to use this in the data
service, since it provides substitutes for derivations, and since these can be
built on other machines, it's useful to control which builtin builders they
depend on.

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.

Previously, ‘latest-channel-instances’ would perform a depth-first
traversal of channels. Since dependencies specified in ‘.guix-channel’
are usually less specific that those provided by the user, this would
lead to the use of instances corresponding to those less specific specs,
which in turn might declare dependencies that do not exist for the more
specific instances.
This commit changes ‘latest-channel-instances’ to perform a
breadth-first traversal, thereby giving user-supplied channels higher
precedence over dependencies found via ‘.guix-channel’.
Fixes <https://issues.guix.gnu.org/68822>.
* guix/channels.scm (latest-channel-instances)[ignore?]: Remove.
[instance-name, same-named?, more-specific?]: New procedures.
Rewrite as a breadth-first traversal using a regular loop.
* tests/channels.scm ("latest-channel-instances reads dependencies from most-specific instance"):

This was obtained by setting up this environment:
guix shell -D guix --with-input=guile@3.0.9=guile-next \
--with-commit=guile-next=e2ed33ef0445c867fe56c247054aa67e834861f2
-- make -j5
then adding 'unused-module' to (@@ (guix build compiler) %warnings),
building, and checking all the "unused module" warnings and removing
those that were definitely unused.
* guix/channels.scm (package-cache-file): Add 'channels' to the #:properties
list.
* guix/status.scm (print-build-event): Upon failure, display a hint when
the derivation is a 'package-cache' hook.
Previously the 'commit' field would always be interpreted as a commit
ID. This change adds flexibility, allowing for things like:
guix time-machine --commit=v1.2.0 -- describe
* guix/channels.scm (channel-reference): Use 'tag-or-commit' rather than 'commit'.
* guix/inferior.scm (channel-full-commit): Likewise.

Previously, news file would be read using the current locale encoding.
This could lead to a test failure in 'tests/channels.scm' (in a test

Fixes a bug introduced in 4ff12d1de7 with
version 4 of the manifest format. A new 'guix time-machine' would
create a v4 manifest; when targeting an old revision (v3),
'generate-package-cache' would fail to read that manifest and abort.
Furthermore, an old Guix living in a new profile with a v4 manifest
would be unable to describe itself via (guix describe).
* guix/channels.scm (package-cache-file): Add 'format-version' field to
PROFILE.
(channel-instances->derivation): Pass #:format-version to
'profile-derivation'.
* guix/channels.scm (package-cache-file): Add a throw handler around
the generate-package-cache call, and print backtrace in it.

This allows computing a manifest for a specific system. Previously this was
possible, but only through changing %current-system, which caused the
derivation to be computed using that system as well (so computing a derivation
for aarch64-linux on x86_64-linux would require running aarch64-linux code).
This new argument adds the possibility of computing derivations for non-native
systems, without having to run non-native code.
I'm looking at this as it will enable the Guix Data Service to compute channel
instance derivations without relying on QEMU emulation for non-native
systems (it should be faster as well).
* guix/channels.scm (build-from-source): Add #:system argument and pass to
build.
(build-channel-instance): Add system argument and pass to build-from-source.
(channel-instance-derivations): Add #:system argument and pass to
build-channel-instance, also rename system to current-system-value.
(channel-instances->manifest): Add #:system argument and pass to
channel-instance-derivations.
This should noticeably speed up compilation for channels with many files.
* guix/channels.scm (standard-module-derivation)[build]: Define
'optimizations-for-level' and '-O1'. Pass #:optimization-options to
'compile-files'.

When the ~/.cache/guix/authentication is empty, this change allows
authentication to start at the current commit, as shown by 'guix

In the end signing the commit/key pair does not buy us much. Someone
publishing a valid but different commit/key pair would effectively be
publishing a different channel, which could be a fork (made by a former

nothing to be gained by publishing a different commit/key pair.

The relation check imposed an extra restriction that was unnecessary:
it's enough to authenticate the set difference between the closure of
START-COMMIT and that of END-COMMIT. Any attempt to jump to an
unrelated commit would lead to the authentication failure of one commit
on the way.
