* syscalls: 'interface-address' can return #f.Ludovic Courtès2016-03-25
| | | | | | | | Fixes <http://bugs.gnu.org/22612>. Reported by Danny Milosavljevic <dannym@scratchpost.org>. * tests/syscalls.scm ("network-interfaces returns one or more interfaces"): Accept 'interface-address' value of #f.
* guix build: '--with-source' correctly matches versioned file names.Ludovic Courtès2016-03-23
| | | | | | | | * guix/scripts/build.scm: Use the right 'package-name->name+version' procedure. Fixes a regression introduced in 1b846da8c372bee78851439fd9e72b2499115e5a. * tests/scripts-build.scm ("options->transformation, with-source, with version"): New test.
* derivations: Raise an error when a module file is not found.Ludovic Courtès2016-03-23
| | | | | | | | | | | | Suggested by Jookia. * guix/derivations.scm (&file-search-error): New error condition. (search-path*): Raise it when 'search-path' returns #f. * guix/gexp.scm (search-path*): Remove. * guix/ui.scm (call-with-error-handling): Add case for 'file-search-error?'. * tests/derivations.scm ("build-expression->derivation and invalid module name"): New test.
* gexp: Add #:disallowed-references.Ludovic Courtès2016-03-20
| | | | | | | | * guix/gexp.scm (gexp->derivation): Add #:disallowed-references and honor it. * tests/gexp.scm ("gexp->derivation #:disallowed-references, allowed") ("gexp->derivation #:disallowed-references"): New tests. * doc/guix.texi (G-Expressions): Adjust accordingly.
* derivations: Add #:disallowed-references.Ludovic Courtès2016-03-20
| | | | | | | | | * guix/derivations.scm (derivation): Add #:disallowed-references. [user+system-env-vars]: Honor it. (build-expression->derivation): Likewise. * tests/derivations.scm ("derivation #:disallowed-references, ok") ("derivation #:disallowed-references, not ok"): New tests. * doc/guix.texi (Derivations): Adjust accordingly.
* import: pypi: Emit 'pypi-uri' only when it yields the right URL.Ludovic Courtès2016-03-19
| | | | | | | | | | | | Fixes <http://bugs.gnu.org/23062>. Reported by Danny Milosavljevic <dannym@scratchpost.org>. * guix/import/pypi.scm (make-pypi-sexp): Check whether 'pypi-uri' returns SOURCE-URL and fall back to the full URL otherwise. * tests/pypi.scm ("pypi->guix-package"): Adjust expected URI accordingly. Co-authored-by: Danny Milosavljevic <dannym@scratchpost.org>
* substitute: Honor client-provided empty URL list.Ludovic Courtès2016-03-16
| | | | | | | | | | | | | | | Before that, 'guix build --substitute-urls=""' would lead to using the daemon's own URL list instead of the empty list. The 'or*' hack, which is to blame, had become unnecessary since commit fb4bf72be3fbc23bca35ba4b842b7e1517ef0e3a. Reported by Mark H Weaver <mhw@netris.org>. * guix/scripts/substitute.scm (or*): Remove. (%cache-urls): Use 'or' instead of 'or*'. * tests/store.scm ("substitute query, alternating URLs"): Add test with empty URL list. * doc/guix.texi (Common Build Options): Mention the empty string.
* upstream: Fix 'signature-urls' coalescing.Ludovic Courtès2016-03-09
| | | | | | | | | Previously, the resulting 'signature-urls' would contain N times the same URL. * guix/upstream.scm (coalesce-sources): Fix TWO in 'signature-urls'. * tests/upstream.scm: New file. * Makefile.am (SCM_TESTS): Add it.
* packages: Gracefully report packages not found.Ludovic Courtès2016-03-08
| | | | | | | | Fixes a thinko introduced in 1b846da8c372bee78851439fd9e72b2499115e5a that would lead to a backtrace when looking for an unknown package. * gnu/packages.scm (%find-package): Correct logic when checking for FALLBACK?.
* packages: Support the deprecated "NAME-VERSION" syntax.Ludovic Courtès2016-03-08
| | | | | | | | | Fixes a typo introduced in 1b846da8c372bee78851439fd9e72b2499115e5a that would lead to a backtrace when using the deprecated syntax. * gnu/packages.scm (%find-package): Turn the first argument to 'call-with-values' into a thunk. Use #:select instead of '@' to select the right 'package-name->name+version' procedure.
* tests: Disable grafting by default for most tests.Ludovic Courtès2016-03-06
| | | | | | | | | | | | | | | This allows tests to run as expected even in the presence of replacements among the bootstrap packages, such as Perl (commit d8173f21f7b4e3cb83541b8fa70621d2b6d4ce1c). * tests/cpan.scm: Add (%graft? #f). * tests/derivations.scm: Likewise. * tests/graph.scm: Likewise. * tests/monads.scm: Likewise. * tests/profiles.scm: Likewise. * tests/gexp.scm: Likewise. ("gexp->derivation vs. grafts"): Explicitly reenable grafting before, and disable it after, using 'set-grafting'.
* tests: Disable tests that would rebuild the world due to grafting.Ludovic Courtès2016-03-05
| | | | | | | | | | The Perl replacement added in d8173f2 leads some tests to involve grafting, which in turn triggers derivation builds that rebuild the world. Work around that. * tests/packages.scm: Add call to '%graft?'. ("package-derivation, direct graft") ("package-cross-derivation, direct graft"): Comment out.
* packages: The result of 'bag-grafts' does not contain duplicates.Ludovic Courtès2016-03-05
| | | | * guix/packages.scm (bag-grafts): Add call to 'delete-duplicates'.
* store: Add 'references/substitutes'.Ludovic Courtès2016-03-05
| | | | | | * guix/store.scm (references/substitutes): New procedure. * tests/store.scm ("references/substitutes missing reference info") ("references/substitutes with substitute info"): New tests.
* 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.

| | | | | | | | | | | Fixes <http://bugs.gnu.org/22872>. Reported by myglc2 <myglc2@gmail.com>. * test-env.in: Define and export 'GUIX_BUILD_OPTIONS'. * tests/guix-build.sh: When setting 'GUIX_BUILD_OPTIONS', make sure it contains '--no-grafts'. * tests/guix-package.sh: Likewise. * tests/guix-daemon.sh: Add (%graft? #f) in Scheme snippets.
* grafts: Graft recursively.Ludovic Courtès2016-03-01
| | | | | | | | | | | | | | | | | | | | | | Fixes <http://bugs.gnu.org/22139>. * guix/grafts.scm (graft-derivation): Rename to... (graft-derivation/shallow): ... this. (graft-origin-file-name, item->deriver, non-self-references) (cumulative-grafts, graft-derivation): New procedures * tests/grafts.scm ("graft-derivation, grafted item is a direct dependency"): Clarify title. Use 'grafted' instead of 'graft' to refer to the grafted derivation. ("graft-derivation, grafted item is an indirect dependency") ("graft-derivation, no dependencies on grafted output"): New tests. * guix/packages.scm (input-graft): Change to take a package instead of an input. (input-cross-graft): Likewise. (fold-bag-dependencies): New procedure. (bag-grafts): Rewrite in terms of 'fold-bag-dependencies'. * tests/packages.scm ("package-derivation, indirect grafts"): Comment out. * doc/guix.texi (Security Updates): Mention run-time dependencies and recursive grafting.
* grafts: Consider all the outputs in the graft mapping.Ludovic Courtès2016-02-27
| | | | | | | | | | | Before that, outputs of a derivation could be left referring to the ungrafted version of the derivation. * guix/grafts.scm (graft-derivation)[outputs]: Change to a list of name/file pairs. * guix/grafts.scm (graft-derivation)[build]: Add 'old-outputs' variable and use it when computing 'mapping'. Use 'mapping' directly. * tests/grafts.scm ("graft-derivation, multiple outputs"): New test.
* store: 'path-info-deriver' is #f when there is no deriver.Ludovic Courtès2016-02-26
| | | | | | | * guix/store.scm (read-path-info): Use #f when we get the empty string for DERIVER. * guix/scripts/publish.scm (narinfo-string): Adjust accordingly. * tests/store.scm ("path-info-deriver"): New test.
* publish: Do not publish nars for invalid store items.Ludovic Courtès2016-02-25
| | | | | | | | | | | Before that, /nar requests could succeed if the requested store item exists but is invalid (although such requests were unlikely because the corresponding narinfo request would have failed.) * guix/scripts/publish.scm (render-nar): Add 'store' parameter. Use 'valid-path?' instead of 'file-exists?'. (make-request-handler): Adjust 'render-nar' call accordingly. * tests/publish.scm ("/nar/invalid"): New test.
