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.

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.

In some cases 'send-files' would return before the other end is done

accordingly.
* guix/scripts/package.scm (%options): Adapt option processors to accept and
return a second seed value: 'arg-handler', which handles bare arguments (if
not false). The install, remove, and upgrade option processors return an
arg-handler that repeat the same operation. All other option processors
return #f as the arg-handler. Make the arguments to install and remove
optional. The upgrade option processor deletes (upgrade . #f) from the
alist before adding a new entry.

Reported by Nikita Karetnikov and Eric Bavier.

tests.

* guix/http-client.scm (when-guile<=2.0.5, http-fetch): Likewise.
* guix/scripts/substitute-binary.scm (fetch): In the `file' case, open
with the `b' flag, so that the coding cookie reading thing doesn't
lead to buffering some of the data (on 2.0.5).

test failure with Guile 2.0.5 whereby the first byte of FILE would be
missing from DECOMPRESSED.
* guix/scripts/package.scm (guix-package)[process-actions](same-package?):
New procedure. Use it instead of `alist-delete' when filtering out
duplicate packages from the profile.
This fixes a bug whereby a command like

would only succeed when the outputs of that package are available, and
otherwise fail with "/nix/store/... is not valid".

the owner of %PROFILE-DIRECTORY. Report an error when the owner is
not the current user. Add `rtfm' procedure.
* doc/guix.texi (Invoking guix package): Mention the ownership test.
This fixes a bug whereby `read-response' would read more than just the
response, with the extra data going into the port's buffer; the
"bzip2 -dc" process spawned by `filtered-port' would not see the those
buffered data, which are definitely lost, and would bail out with
"bzip2: (stdin) is not a bzip2 file."
* guix/utils.scm (filtered-port): Document that INPUT must be
unbuffered.
* guix/web.scm (http-fetch): Add `buffered?' parameter. Call
`open-socket-for-uri' explicitly, and call `setvbuf' when BUFFERED? is
false. Pass the port to `http-get'. Close it upon 301/302.
* guix/scripts/substitute-binary.scm (fetch): Add `buffered?'
parameter. Pass it to `http-fetch'; honor it for `file' URIs.
(guix-substitute-binary): Call `fetch' with #:buffered? #f for port RAW.
* tests/utils.scm ("filtered-port, file"): Open FILE as unbuffered.

* guix/scripts/package.scm (guix-package)[process-actions](package->tuple):
Put the output path in the tuple, not the derivation path.
* tests/guix-package.sh: Add test.
Before this, something like "guix package -i glibc" could fail because
glibc lists linux-libre-headers as a propagated input (which would be
added as a dependency in the manifest) but the linux-libre-headers
output could be unavailable, leading to an error like this:
path `/nix/store/4v2bk8sx5cm166gks3fi3q7d9zchibnk-linux-libre-headers-3.3.8' is not valid
This patch adds such dependencies as inputs of the profile derivation.
* guix/scripts/package.scm (profile-derivation): Accept package objects
in the `deps' field of an element of PACKAGES. Convert them to their
output path for BUILDER, and add them to the inputs of the
`build-expression->derivation' call.

return it as is.
(guix-package)[process-actions](canonicalize-deps): Expect DEPS to

gracefully handle the case where TARBALL is #f.
Reported by Nikita Karetnikov <nikita@karetnikov.org>.

%USER-ENVIRONMENT-DIRECTORY when it points to PROFILE.
(display-search-paths): Use 3 spaces for indentation.
* guix/scripts/package.scm (guix-package)[find-package]: Add optional
parameter `output'. Use it.
[process-actions]: When computing UPGRADE, pass OUTPUT to
`find-package'.
