Fixes <http://bugs.gnu.org/21773>.
Reported by Jan Synáček <jan.synacek@gmail.com>.
* guix/ui.scm (make-regexp*): New procedure.
* guix/scripts/package.scm (options->installable, guix-package): Use it
when processing user-provided regexps.
* gnu/build/linux-container.scm (namespaces->bit-mask): Remove
CLONE_CHILD_CLEARTID and CLONE_CHILD_SETTID, which are unneeded.
Discussed at <http://bugs.gnu.org/21694>.
Partly fixes <http://bugs.gnu.org/20217>.
* guix/store.scm (set-build-options): Change #:substitute-urls to
default to #f. Send the 'substitute-urls' pair only if
SUBSTITUTE-URLS is true.
* guix/scripts/build.scm (set-build-options-from-command-line): Do not
default to %DEFAULT-SUBSTITUTE-URLS for #:substitute-urls.
* guix/scripts/size.scm (%default-options): Remove 'substitute-urls'.
* guix/scripts/substitute.scm (lookup-narinfos/diverse): New procedure.
(lookup-narinfo): Use it.
(process-query): Change #:cache-url to #:cache-urls.
[valid?]: Remove 'narinfo?' check, which is no longer necessary.
Use 'lookup-narinfos/diverse' instead of 'lookup-narinfos'.
(process-substitution): Change #:cache-url to #:cache-urls.
(%cache-url): Rename to...
(%cache-urls): ... this. Turn into a list.
(guix-substitute): Remove 'getaddrinfo' test with early exit. Adjust
calls to 'process-query' and 'process-substitution'.
* tests/substitute.scm: Change '%cache-url' to '%cache-urls'.
* guix/scripts/substitute.scm (lookup-narinfos): Filter out #f values
from CACHED, such that the end result is exactly a list of narinfos,
not interspersed with #f.
* guix/scripts/challenge.scm (discrepancies): Assume REMOTE is a list of
narinfos.
* gnu/packages/grub.scm (grub)[arguments]: Use modify-phases. Return #t from
'patch-stuff' phase. Add 'patch-stuff' phase after 'unpack' instead of
before 'patch-source-shebangs'.
[inputs]: Add comment noting that 'fuse' would be a desirable input.
* gnu/system/grub.scm (eye-candy): Accept additional 'system' argument. Add
local 'setup-gfxterm-body' variable. Replace the 'load_video' grub function
with 'setup_gfxterm', which includes everything in the 'if loadfont' form on
Intel systems, but is empty on non-Intel.
(grub-configuration-file): Pass 'system' to 'eye-candy.
This is a followup to commit 06d45f4566.
* emacs/guix-base.el (guix-switch-to-generation): Replace
'switch-to-generation' with 'switch-to-generation*'.
* guix/scripts/package.scm (delete-generations): Use
'delete-generation*' instead of 'delete-generation'.
(guix-package)[process-actions]: Use 'roll-back*' instead of
'roll-back' and 'switch-to-generation*' instead of
'switch-to-generation'.
(link-to-empty-profile, switch-to-generation,
switch-to-previous-generation, roll-back, delete-generation): Move
to...
* guix/profiles.scm: ... here. Adjust to not print messages and to
return values that can be used by user interfaces.
* guix/ui.scm (display-generation-change, roll-back*,
switch-to-generation*, delete-generation*): New procedures.
* guix/scripts/system.scm (<boot-parameters>): New record type.
(read-boot-parameters): New procedure.
(previous-grub-entries)[system->grub-entry]: Use it.
* guix/scripts/package.scm (guix-package)[process-query](list-generations):
Move part of the body to 'delete-generation' and
'display-profile-content'.
* guix/ui.scm (display-generation, display-profile-content): New
procedures.
