* guix build: Set the build options early.Ludovic Courtès2016-03-05
| | | | | | | | | | | | This fixes a bug whereby, with grafts leading to builds very early, build options such as --substitute-urls would not be taken into account yet. Reported by Andreas Enge <andreas@enge.fr>. * guix/scripts/build.scm (guix-build): Move 'opts' to the beginning. Use 'with-store' instead of 'open-connection'. Call 'set-build-options-from-command-line' right after 'with-store'.
* lint: cve: Gracefully handle HTTP errors.Ludovic Courtès2016-03-04
| | | | | * guix/scripts/lint.scm (current-vulnerabilities*): New procedure. (package-vulnerabilities): Use it.
* lint: derivation: Disable grafts, but check replacements.Ludovic Courtès2016-03-03
| | | | | * guix/scripts/lint.scm (check-derivation): Pass #:graft? #f. When 'package-replacement' exists, compute its derivation.
* guix build: -S returns the replacement's source.Ludovic Courtès2016-03-03
| | | | | | | | Reported by Mark H Weaver. * guix/scripts/build.scm (options->derivations): When SRC and GRAFT? are true, use the source of P's replacement. * tests/guix-build.sh: Add test.
* utils: Use '@' for separating package names and version numbers.Mathieu Lirzin2016-03-02
| | | | | | | | | | | | | | | | | | | | | This provides the ability to use numbers in package names. Fixes <http://bugs.gnu.org/19219>. * guix/utils.scm (package-name->name+version): New procedure. * gnu/packages.scm (%find-package): Add a FALLBACK? keyword argument. Use the previous method when no package is found. (specification->package+output, specification->package): Adapt documentation to new syntax. * doc/guix.texi (Invoking guix package, Invoking guix import): Likewise. * guix/ui.scm (package-specification->name+version+output): Likewise. * guix/scripts/import/hackage.scm (show-help): Likewise. * tests/guix-build.sh: Adapt to new syntax. * tests/guix-lint.sh: Likewise. * tests/guix-package.sh: Likewise. * tests/ui.scm ("package-specification->name+version+output"): Likewise. * tests/utils.scm ("package-name->name+version"): Likewise. * NEWS: Mention new syntax.
