Fixes <http://bugs.gnu.org/19598>.
Reported by Mark H Weaver <mhw@netris.org>.
* gnu/packages/cross-base.scm (xgcc-mips64el): Remove "i686-linux" from
'supported-systems'.
* tests/lint.scm (%http-server-lock, %http-server-ready): New
variables.
(http-open): New procedure.
(stub-http-server): Use it.
(call-with-http-server): Wrap body in 'with-mutex'. Call
'wait-condition-variable' after 'make-thread'.
* doc/guix.texi (GNU Distribution): Explain what "Guixotic" is.
(System Installation): Replace "the GNU system" by "Guixotic".
(System Configuration): Likewise.
(Invoking guix system): Likewise.
Reported by Mark H Weaver <mhw@netris.org>
* guix/build/glib-or-gtk-build-system.scm (generate-icon-cache): Add check for
existence of icons directory.
* gnu/packages/gnome.scm (evince): Add 'dconf' and 'libcanberra' inputs.
Remove custom phase 'set-mime-search-path which is now handled by
glib-or-gtk-build-system.
* gnu/packages/libcanberra.scm (libcanberra): Add input
'sound-theme-freedesktop'. Add "libcanberra-sound-theme-freedesktop.patch"
and related phase 'patch-default-sounds-directory to patch the default
sounds directory.
* guix/build/glib-or-gtk-build-system.scm (data-directories): Rename
'schemas-directories' to 'data-directories' and add support for XDG theming
data.
* guix/build/glib-or-gtk-build-system.scm (gio-module-directories): New
function.
* guix/build/glib-or-gtk-build-system.scm (wrap-all-programs): Update names to
reflect that we are dealing with more types of data and not only with
schemas. Add handling of GIO modules.
* guix/build-system/glib-or-gtk.scm (lower): Import the 'bin' output of GLib
instead of 'out'. This was an error since we need the program
'glib-compile-schemas'. Update the description.
This yields a 46% improvement in 'derivation-prerequisites' invocations
on the Emacs derivation.
* guix/derivations.scm (derivation-prerequisites): Add 'input-set'
variable, and use it in iterations.
This makes 'guix environment PACKAGE' significantly faster when
substitutes are enabled. Before that, it would lead to many invocations
of 'guix substitute-binary', one per 'derivation-prerequisites-to-build'
call. Now, all these are replaced by a single invocation.
* guix/derivations.scm (derivation-output-paths, substitution-oracle):
New procedures.
(derivation-prerequisites-to-build): Replace #:use-substitutes? with
#:substitutable?. Remove the local 'derivation-output-paths' and
'substitutable?'.
* guix/ui.scm (show-what-to-build): Add 'substitutable?'. Pass it to
'derivation-prerequisites-to-build'.
[built-or-substitutable?]: Use it instead of 'has-substitutes?'.
* tests/derivations.scm ("derivation-prerequisites-to-build and
substitutes"): Use #:substitutable? instead of #:use-substitutes?.
* guix/derivations.scm (derivation-output-names): New procedure.
(derivation-prerequisites-to-build): Use it for #:outputs.
(map-derivation): Likewise.
* tests/derivations.scm ("derivation-output-names"): New test.
* guix/build/utils.scm (patch-/usr/bin/file): New procedure.
* guix/build/gnu-build-system.scm (patch-usr-bin-file): Rewrite using
it. Patch all the files returned by 'find-files' that are executable.
* gnu/packages/gawk.scm (gawk)[arguments]: Remove use of 'substitute*'
for 'extension/configure'.
