This fixes a bug whereby "guix build texlive -n" would report:
0.0 MB would be downloaded:
/gnu/store/…-texlive-20180414
instead of:
The following derivation would be built:
/gnu/store/…-texlive-texmf-20180414.drv
2,595.2 MB would be downloaded:
/gnu/store/…-texlive-20180414-texmf.tar.xz
/gnu/store/…-texlive-20180414
where 'texlive-texmf' is a non-substitutable dependency of 'texlive'.
* guix/derivations.scm (dependencies-of-substitutables): New procedure.
(derivation-build-plan): When 'input-substitutable-info' returns true,
append the subset of DEPS that corresponds to SUBSTITUABLES to the first
argument of 'loop'.
* guix/ui.scm (show-what-to-build): Remove half-baked traversal of
DOWNLOAD.
* tests/derivations.scm ("derivation-build-plan and substitutes,
non-substitutable dep"): New test.
* guix/scripts/pack.scm (singularity-environment-file): New procedure.
(squashfs-image): Use it, and create /.singularity/env/90-environment.sh.
* gnu/tests/singularity.scm (run-singularity-test)["singularity run,
with environment"]: New test, currently skipped.
* gnu/tests/singularity.scm (build-tarball&run-singularity-test): Add
GUILE-JSON to the profile.
* guix/docker.scm (config): Add #:environment parameter and honor it.
(build-docker-image): Likewise, and pass it to 'config'.
* guix/scripts/pack.scm (docker-image): Import (guix profiles) and (guix
search-paths). Call 'profile-search-paths' and pass #:environment to
'build-docker-image'.
* gnu/tests/docker.scm (run-docker-test)["Load docker image and run it"]:
Add example that expects (json) to be available.
* gnu/tests/docker.scm (build-tarball&run-docker-test): Replace
%BOOTSTRAP-GUILE by GUILE-2.2 and GUILE-JSON in the environment.
* guix/gexp.scm (gexp-input-thing, gexp-input-output)
(gexp-input-native?): Export.
(lower-inputs): Return <gexp-input> records instead of tuples.
(lower-reference-graphs): Adjust accordingly.
(<lowered-gexp>): New record type.
(lower-gexp, gexp-input->tuple): New procedure.
(gexp->derivation)[%modules]: Remove.
[requested-graft?]: New variable.
[add-modules]: New procedure.
Rewrite in terms of 'lower-gexp'.
(gexp-inputs): Add TODO comment.
* tests/gexp.scm ("lower-gexp"): New test.
This increases the hit rate of the object cache from 56% to 85% when
running something like 'guix build libreoffice -nd'.
* guix/store.scm (set-store-connection-object-cache!): New procedure.
(run-with-store): Copy 'object-cache' field of the new store into the
original one.
This is a followup to 5cf4b26d52.
* guix/derivations.scm (substitution-oracle): Use
'derivation-input-derivation' instead of calling
'read-derivation-from-file'.
This is a followup to 5cf4b26d52.
* guix/derivations.scm (derivation-path->base16-hash): Rename to...
(derivation-base16-hash): ... this, and take a <derivation> rather than
a file name. Use 'mlambdaq' instead of 'mlambda'.
(derivation/masked-inputs): Adjust accordingly.
(invalidate-derivation-caches!): Likewise.
