* guix/derivations.scm (valid-derivation-input?): New procedure.
(derivation-prerequisites): Add 'cut?' parameter and honor it.
* tests/derivations.scm ("derivation-prerequisites and
derivation-input-is-valid?"): New test.
* gnu/packages/python.scm (python-2): Add rpath for lib directory of output to
LDFLAGS. Remove 'patchelf' from inputs. Remove #:modules and
#:imported-modules from arguments. Remove 'add-lib-to-runpath' phase.
(python): Do not add #:modules to inherited package arguments.
Fixes <http://bugs.gnu.org/20188>.
Reported by Mark H Weaver <mhw@netris.org>.
* guix/derivations.scm (substitution-oracle): Add 'valid?' procedure.
Remove 'valid?' items from PATHS.
Fixes a regression introduced in 666aa99.
Reported by Felipe López and David Thompson.
* gnu/packages/sdl.scm (sdl)[inputs]: Add glu.
[arguments]<#:configure-flags>: Replace '--disable-sdl-dlopen' with
'--disable-alsa-shared --disable-pulseaudio-shared --disable-x11-shared'.
Fixes <http://bugs.gnu.org/20163>.
Reported by Mark H Weaver <mhw@netris.org>.
* guix/store.scm (%default-substitute-urls): New variable.
(set-build-options): Change default value of #:substitute-urls to
%DEFAULT-SUBSTITUTE-URLS.
* guix/gexp.scm (gexp-inputs): Remove 'references' parameter; add
#:native? and honor it.
[add-reference-inputs]: Distinguish between native gexp inputs, and
non-native gexp inputs. Honor 'native?' field of list inputs.
* tests/gexp.scm ("ungexp + ungexp-native, nested"): New test.
Before that, the 'references' and 'natives' or the outer gexp in an
expression like #~#+#~#$coreutils would include those of the inner
gexp.
* guix/gexp.scm (gexp)[collect-escapes]: Ignore everything below
'ungexp-native' or 'ungexp-native-splicing'.
[collect-native-escapes]: Ignore everything below 'ungexp' or
'ungexp-splicing'.
* gnu/packages/video.scm (mplayer2): New variable.
* gnu/packages/patches/mplayer2-theora-fix.patch: New file.
* gnu-system.am (dist_patch_DATA): Add it.
* gnu/packages/glib.scm (python-pygobject)[home-page]: Use home page of the
3.x series of the pygobject bindings instead of the home page for the 2.x
bindings.
Before that it would sort them by name only, so the order in which two
packages with the same name but a different version would appear was
non-deterministic.
Reported by Tomáš Čech <sleep_walker@gnu.org>.
* guix/scripts/package.scm (find-packages-by-description)[version<?]:
New variable.
Change the 2nd argument to 'sort' to use 'string-compare' and resort
to 'version<?' when P1 and P2 have the same name.
Before that, 'guix package -s foobarbaz' would display only one package
when several match but they have the same location (which is common when
using 'inherit'.)
The original rationale was given at
<http://lists.gnu.org/archive/html/bug-guix/2013-01/msg00280.html> but
it was arguably misguided because it led to "real" packages being
hidden.
Reported by Tomáš Čech <sleep_walker@gnu.org>.
* guix/scripts/package.scm (find-packages-by-description)[same-location?]:
Remove.
Remove call to 'delete-duplicates'.
