This ensures that channel modules are compiled with the right Guile,
that they get to see the right modules, and so on. IOW, it avoids bugs
such as those addressed by commits
3c0e16391e and
cb341c1219.
* guix/channels.scm (standard-module-derivation): Add 'core'
parameter. Rewrite in terms of 'gexp->derivation-in-inferior'.
(build-from-source): Add #:core parameter and pass it to
'standard-module-derivation'.
(build-channel-instance): Add 'core' parameter and pass it on.
(channel-instance-derivations)[dependencies]: Remove.
Adjust 'build-channel-instance' call.
Previously the imported modules and extensions of EXP would be missing
from the load path of 'guix repl'.
* guix/inferior.scm (gexp->derivation-in-inferior)[script]: New
variable.
[trampoline]: Write (primitive-load #$script) to PIPE. Add #$output.
* tests/channels.scm ("channel-instances->manifest")[depends?]: Check
for requisites rather than direct references.
Adjust callers accordingly.
Previous 'channel-instance->manifest' would call
'latest-channel-derivation', which could trigger another round of
'latest-repository-commit' for no good reason.
* guix/channels.scm (resolve-dependencies): New procedure.
(channel-instance-derivations)[edges]: New variable.
[instance->derivation]: New procedure.
* tests/channels.scm (make-instance): Use 'checkout->channel-instance'
instead of 'channel-instance'.
("channel-instances->manifest"): New test.
This fixes a regression introduced in
b5f8c2c885 whereby 'current-guix' (needed
by some of the system tests) would fail to build.
Reported by Ricardo Wurmus <rekado@elephly.net>.
It also speeds up compilation of 'current-guix' since the channel
instance is already compiled or can be built quickly compared to the
default 'current-guix'.
* gnu/packages/package-management.scm (current-guix-package): New
variable.
(current-guix): Honor it.
* gnu/ci.scm (channel-build-system): New variable.
(channel-instances->derivation): New procedure.
(system-test-jobs): Add #:source and #:commit parameters.
Define 'instance' and parameterize CURRENT-GUIX-PACKAGE.
(hydra-jobs)[checkout, commit, source]: New variables.
Pass #:source and #:commit to 'system-test-jobs'.
* guix/build/profiles.scm (build-etc/profile): When 'OUTPUT/etc/profile'
already exists, delete it first.
(build-profile): Likewise for 'OUTPUT/manifest'.
* tests/profiles.scm ("profile in profile"): New test.
Fixes <https://bugs.gnu.org/33647>.
Suggested by Diego Nicola Barbato <dnbarbato@posteo.de>.
* guix/scripts/pull.scm (build-and-install): Before returning, display a
hint if (which "guix") is not in PROFILE.
Fixes <https://bugs.gnu.org/33603>.
Reported by Maxim Cournoyer <maxim.cournoyer@gmail.com>.
* guix/serialization.scm (port-conversion-strategy): New variable.
(restore-file): Parameterize it.
* tests/nar.scm ("restore-file with non-UTF8 locale"): New test.
It is possible to generate a profile where this hook will crash, as the
texmf.cnf file does not exist to be patched by substitute*. A simple example
is the profile just containing texlive-fonts-txfonts.
* guix/profiles.scm (texlive-configuration): Check that the texmf.cnf file
exists before trying to change it.
