packages: 'specification->package+output' distinguishes "no output specified".

2019-06-27T09:14:41Z

Until now the caller couldn't tell the different between a spec like "foo:out" and one like "foo". This change allows users to distinguish between these two cases. * gnu/packages.scm (specification->package+output): Disable output membership test when OUTPUT = #f and SUB-DRV = #f. * tests/packages.scm ("specification->package+output") ("specification->package+output invalid output") ("specification->package+output no default output") ("specification->package+output invalid output, no default"): New tests.

packages: Reintroduce 'find-newest-available-packages'.

2019-03-28T22:06:58Z

This is a followup to e2a903c807ccacec5925f197ce26f626060e1953. * gnu/packages.scm (find-newest-available-packages): New procedure.

packages: Add the channel .go files to the search path.

2019-03-11T22:12:26Z

Until now %LOAD-COMPILED-PATH would wrongfully contain: CHANNEL/share/guile/site/X.Y for each channel, thereby ignoring all the .go files of channels. This fixes it so that %LOAD-COMPILED-PATH instead contains: CHANNEL/lib/guile/X.Y/site-ccache * guix/describe.scm (current-channel-entries): New procedure. (package-path-entries): Change to return the %LOAD-COMPILED-PATH entries as a second value. * gnu/packages.scm (%package-module-path): Expect two values from 'package-path-entries' and augment %LOAD-COMPILED-PATH accordingly.

packages: Remove duplicates from package cache.

2019-02-16T00:00:08Z

Previously the same package could appear several times if several variables were bound to it, as is notably the case for "python" currently. This, in turn, would lead to obnoxious "ambiguous package specification" messages. * gnu/packages.scm (generate-package-cache)[expand-cache]: Change RESULT to RESULT+SEEN and adjust accordingly. Call 'first' on the result of 'fold-module-public-variables*'. * tests/packages.scm ("fold-available-packages with/without cache"): Check for lack of duplicates in FROM-CACHE.

guix package: '--list-available' can use data from the cache.

2019-01-15T19:24:09Z

* gnu/packages.scm (fold-available-packages): New procedure. * guix/scripts/package.scm (process-query): Use it instead of 'fold-packages'. * tests/packages.scm ("fold-available-packages with/without cache"): New test.

edit: Use 'specification->location' to read information from the cache.

2019-01-15T19:24:09Z

That way 'guix edit' doesn't need to load any package module. * gnu/packages.scm (find-package-locations, specification->location): New procedures. * guix/scripts/edit.scm (package->location-specification): Rename to... (location->location-specification): ... this. Expect a location object instead of a package. (guix-edit): Use 'specification->location' instead of 'specification->package'. * tests/packages.scm ("find-package-locations") ("find-package-locations with cache") ("specification->location"): New tests.

channels: Compute a package cache and use it.

2019-01-15T19:24:09Z

* gnu/packages.scm (cache-is-authoritative?, load-package-cache) (cache-lookup, generate-package-cache): New procedures. (%package-cache-file): New variable. (find-packages-by-name): Rename to... (find-packages-by-name/direct): ... this. (find-packages-by-name): Rewrite to use the package cache when 'cache-is-authoritative?' returns true. * tests/packages.scm ("find-packages-by-name + version, with cache") ("find-packages-by-name with cache"): New tests. * guix/channels.scm (package-cache-file): New procedure. (%channel-profile-hooks): New variable. (channel-instances->derivation): Use it in #:hooks. * guix/scripts/package.scm (build-and-use-profile): Add #:hooks and honor it. * guix/scripts/pull.scm (build-and-install): Pass #:hooks to UPDATE-PROFILE.

packages: Remove 'find-newest-available-packages'.

2019-01-15T19:24:09Z

Since commit 9ffc1c00e55eb7931846dbb3fafcf54716fff57c, 'find-newest-available-packages' and 'find-packages-by-name' were both building a vhash mapping package names to packages. This factorizes this bit, also reducing I/O, CPU, and memory usage. * gnu/packages.scm (find-best-packages-by-name): Remove. (find-best-packages-by-name): Use 'find-packages-by-name' instead of 'find-newest-available-packages'.

Add (guix describe) and use it to initialize '%package-search-path'.

2018-09-02T14:43:10Z

* guix/describe.scm: New file. * Makefile.am (MODULES): Add it. * gnu/packages.scm (%default-package-module-path): New variable. (%package-module-path): Honor 'package-path-entries'. * build-aux/update-NEWS.scm (main): Use %DEFAULT-PACKAGE-MODULE-PATH instead of (last (%package-module-path)).

packages: 'find-packages-by-name' properly honors version prefixes.

2018-05-13T11:29:27Z

Fixes . Reported by Mark H Weaver . * gnu/packages.scm (find-packages-by-name): Use 'version-prefix?' instead of 'string-prefix?'.
