Fixes compilation failures in 'guix pull'.
* guix/import/cpan.scm (%corelist): Change it to a promise by wrapping it with
'delay'.
(cpan-module->sexp): Adapt uses of %corelist by wrapping with 'force'.
Fixes <http://bugs.gnu.org/19840>.
Reported by Ricardo Wurmus <rekado@elephly.net>.
* guix/build/download.scm: On Guile 2.0.11 or earlier, redefine the http
"Location" header to accept relative URIs.
(resolve-uri-reference): New exported procedure.
(http-fetch): Use 'resolve-uri-reference' to resolve redirections.
* guix/http-client.scm (http-fetch): Use 'resolve-uri-reference'

it to 'add-text-to-store'.

at <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=19764#19>.

(get-bytevector-n*): New procedure.
(read-int, read-long-long, read-string, read-latin1-string,
read-contents): Use it instead of 'get-bytevector-n'.
(restore-file): Parameterize 'currently-restored-file' and set it.
* tests/nar.scm ("restore-file with incomplete input"): New test.
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>.

'warning' when it is non-zero.

* guix/store.scm (operation-id): Rename 'build-derivations' to
'build-things', as per Nix commit 1aba0bf0.
(build-derivations): Rename to...
(build-things): ... this. Keep 'build-derivations' as an alias.

"substitute + build-things with output path"): New tests.
* guix/tests.scm (%substitute-directory): New variable.
(call-with-derivation-narinfo): Use it.
(call-with-derivation-substitute): New procedure.
(with-derivation-substitute): New macro.
* tests/store.scm ("substitute"): Use 'with-derivation-substitute'.
("substitute, corrupt output hash"): Likewise.
* guix/tests.scm (derivation-narinfo): Turn 'nar' into a keyword
parameter. Add #:sha256 parameter, and honor it.
(call-with-derivation-narinfo): Add #:sha256 and pass it to
'derivation-narinfo'.
(with-derivation-narinfo): Extend with support for (sha256 => value).
* tests/store.scm ("substitute query"): Use 'with-derivation-narinfo'.
("substitute"): Likewise.
("substitute, corrupt output hash"): Likewise.
("substitute --fallback"): Likewise.
* tests/derivations.scm: Remove Emacs local variable.
* guix/scripts/lint.scm (%options) <--checkers>: Remove 'arg-handler'
parameter, and return a single value.

handlers. Remove second seed to 'args-fold*'.
* tests/guix-lint.sh: Add test.
Fixes <http://bugs.gnu.org/19677>.
Reported by Mark H Weaver <mhw@netris.org>.
* guix/hash.scm: Use (guix gcrypt).
(sha256, open-sha256-md, md-write, md-close): Use 'libgcrypt-func'
instead of 'dynamic-func'.
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'.
Fixes <http://bugs.gnu.org/19630>.

* guix/derivations.scm (&derivation-error,
&derivation-missing-output-error): New error conditions.
(derivation->output-path): Raise a '&derivation-missing-output-error'
if OUTPUT is not an output of DRV.
