* guix/scripts/package.scm (build-and-use-profile): New procedure.
Adapted and moved from...
(guix-package)[process-actions]: ... here. Adjust call sites.
This is a followup to b68d2db, which added a check for updaters at
macro-expansion time. The problem is that, when running 'guix pull',
Guile-JSON is found, so the PyPi updater (say) is added to %UPDATERS,
but then at run time Guile-JSON might be missing.
Reported by orbea on #guix.
* guix/scripts/refresh.scm (maybe-updater): Rewrite as 'syntax-rules'.
Produce code that checks conditions at run time.

Discussed in <http://bugs.gnu.org/20255>.
* guix/packages.scm (sexp->search-path-specification): New variable.
* guix/profiles.scm (<manifest-entry>)[search-paths]: New field.
(package->manifest-entry): Initialize it.
(manifest->gexp): Match it. Wrap #$deps in (propagated-inputs ...).
Emit (search-paths ...). Increment version.
(find-package): New procedure.
(sexp->manifest)[infer-search-paths]: New procedure.
Use it to initialize the 'search-paths' field for versions 0 and 1.
Add case for version 2.
* guix/scripts/package.scm (search-path-environment-variables)[manifest-entry->package]:
Remove.
Use 'manifest-entry-search-paths' instead of 'manifest-entry->package'
plus 'package-native-search-paths'.
* tests/profiles.scm ("profile-manifest, search-paths"): New test.
In practice we would not leak much since we reconnect after ~100
requests (with nginx running on hydra.gnu.org.)
* guix/scripts/substitute.scm (http-multiple-get): Call 'close-port'
before 'connect'.
* guix/scripts/refresh.scm (guix-refresh): Use 'specification->package'
instead of 'find-packages-by-name'. This allows users to specify
things like "qt-4.8.6".

#:ghc-package-cache? to 'profile-generation'.
* tests/packages.scm ("--search-paths with pattern"): Likewise.
* tests/profiles.scm ("profile-derivation"): Likewise.

'exit' when PATTERN is "0". Call 'leave' instead of 'exit'
when (null-list? number).
Fixes <http://bugs.gnu.org/19978>.
Reported by taylanbayirli@gmail.com (Taylan Ulrich Bayırlı/Kammer).
* guix/scripts/package.scm (delete-matching-generations): Warn when
CURRENT is in NUMBERS, and always remove it before calling
'delete-generations'.
* tests/guix-package.sh: Add --switch-generation=2 invocation before
--delete-generations=3 invocation.
Add --delete-generations=1.. test case.
* guix/scripts/package.scm (delete-matching-generations): New procedure,
with code formerly found...
(guix-package)[process-actions]: ... here. Use it.
Remove 'current-generation-number'.
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'.
* guix/store.scm (set-build-options): Rename #:binary-caches to
#:substitute-urls. Actually pass it in 'pairs' under the
"substitute-urls" key.
* guix/scripts/substitute-binary.scm (%cache-url): Add comment for
"untrusted-substitute-urls".
This fixes a regression introduced in commit 536c3ee.
* guix/profiles.scm (ca-certificate-bundle): When MANIFEST is empty,
make a trivial derivation.
* guix/scripts/package.scm (guix-package)[process-actions]: Pass
#:ca-certificate-bundle? to 'profile-generation'.
* tests/packages.scm ("--search-paths with pattern"): Likewise.
* tests/profiles.scm ("profile-derivation"): Likewise.
Before that, any profile generation built when '-p' is used would
effectively become a permanent GC root because the symlink in
/var/guix/gcroots/auto would point directly to /gnu/store/...-profile.
* guix/scripts/package.scm (maybe-register-gc-root): Rename to...
(register-gc-root): ... this. Remove conditional, and replace call to
'canonicalize-path' with (string-append (getcwd) "/" ...).
(guix-package): Call 'register-gc-root' only if PROFILE is different
from %CURRENT-PROFILE.
* tests/guix-package.sh: Add test case.
Before that, if two users on the same machine ran 'guix pull', the
second one would have the "Guix already up to date" message and their
~/.config/guix/latest link would be left unchanged---effectively
preventing them from updating.
* guix/scripts/pull.scm (build-and-install): Install the 'latest'
symlink regardless of whether TO-DO? is true or false.
Suggested by Ricardo Wurmus <ricardo.wurmus@mdc-berlin.de>.
* guix/scripts/offload.scm (register-gc-root)[script]: Replace
'false-if-exception' with a finer-grain 'system-error handler.
Provide the name of MACHINE in 'leave' error message.
Suggested by Ricardo Wurmus <ricardo.wurmus@mdc-berlin.de>.
* guix/scripts/offload.scm (remote-pipe): Remove unneeded 'catch'.
(machine-load): Check the exit value upon (close-pipe pipe). Call
'warning' when it is non-zero.
* guix/scripts/environment.scm (for-each-search-path): Iterate over all
derivation output paths.
(packages->transitive-inputs): Process inputs that specify an output, too.
* guix/scripts/lint.scm (%options) <--checkers>: Remove 'arg-handler'
parameter, and return a single value.
(guix-lint)[parse-options]: Remove 'arg-handler' parameter from
handlers. Remove second seed to 'args-fold*'.
* tests/guix-lint.sh: Add test.
Before that it would check all the URIs of each package.
* guix/scripts/lint.scm (validate-uri): Really return #f on failure and
#t otherwise.
(check-source): Replace 'for-each' with 'any'.
* guix/ui.scm (report-error): Export.
* guix/scripts/system.scm (read-operating-system): Report syntax errors
using standard GNU format. Report other errors using 'display-error'.
Reported by Andreas Enge <andreas@enge.fr>.
* guix/scripts/package.scm (with-null-error-port): New macro.
(search-path-environment-variables): Wrap 'search-path-as-list' call
in 'with-null-error-port'.
* guix/scripts/substitute-binary.scm (narinfo-signature->canonical-sexp):
Change "~a" to "~s" in error message.
(%signature-line-rx): Remove.
(narinfo-sha256): Use 'string-contains' instead of 'regexp-exec', and
'string-take' instead of 'match:substring'.
* guix/scripts/package.scm (search-path-environment-variables): Add
local 'files' variable.
* tests/packages.scm ("--search-paths with pattern"): New test.
* guix/scripts/lint.scm (run-checkers): Check
whether (current-error-port) is a tty, and print the package being
checked and the checker currently running when it is.
This will handle the new 'file-type' and 'file-pattern' fields correctly.
* guix/scripts/package.scm (search-path-environment-variables)[search-path-definition]:
Rewrite in terms of 'search-path-as-list'.
This would not work when /boot is a separate partition, as reported by
Nikita Karetnikov <nikita@karetnikov.org> in <http://bugs.gnu.org/19220>.
This fixes a regression introduced in 39d1f82.
* gnu/build/install.scm (install-grub): Copy GRUB.CFG instead of
symlinking it, as was the case before 39d1f82.
* gnu/build/vm.scm (register-grub.cfg-root): Add 'grub.cfg' parameter.
Make it a permanent GC root instead of an indirect GC root.
(initialize-hard-disk): Adjust accordingly.
* guix/scripts/system.scm (install-grub*): Replace use of
'add-indirect-root' by the addition of a permanent GC root in
%GC-ROOTS-DIRECTORY.
Fixes <http://bugs.gnu.org/19279>.
Fixes a regression introduced in cc7fa59.
Reported by Tomas Cech <tcech@suse.cz>.
* guix/scripts/system.scm (install): Fix order of arguments to 'lift'
and 'lift2'.
Appending to "raw" args broke optional parameters in 'guix package -I'
and 'guix package -A', and possibly other places. Therefore, switch to
parsing each set of options on its own and append resulting alists
together afterwards.
* guix/scripts/archive.scm (parse-options-from): Rename from
(parse-options) and add explicit argument. New form of (parse-options)
using its old algorithm via -from function.
* guix/scripts/build.scm: Ditto.
* guix/scripts/environment.scm: Ditto.
* guix/scripts/package.scm: Ditto.
* guix/scripts/system.scm: Ditto.
* tests/guix-package.sh: Add test.
* doc/guix.texi (Invoking guix build): Make it clear that the options
are parsed independently.
