This fixes two problems:
1. Load errors would print an ugly backtrace.
2. When FILE was an absolute name, 'load' was passed an incorrect file
name.
* guix/scripts/environment.scm (options/resolve-packages): Use 'load*' instead
of 'load'.
* guix/scripts/environment.scm (package+propagated-inputs): Add 'output'
parameter. Use it in return value.
(options/resolve-packages): Use 'append-map' instead of 'map'. For 'load'
and 'expression', return all the outputs of the resulting package. For
'package', use 'specification->package+output' instead of
'specification->package'.
(guix-environment): Adjust uses of PACKAGES accordingly.
* doc/guix.texi (Invoking guix environment): Document it.
* tests/guix-environment.sh: Add test for --ad-hoc guile-bootstrap:out.
Before that, 'guix environment guile' (for instance) would define environment
variables that would refer to the "include" output of Bash, the "debug" output
of libgc, etc., even though these are not listed as inputs in the recipe of
'guile'.
* guix/gexp.scm (lower-inputs): Export.
* guix/scripts/environment.scm (evaluate-input-search-paths): Remove
'derivations' parameter; add 'search-paths'. Expect 'inputs' to be
a list of tuples. Adjust callers.

(show-search-paths): Likewise.
(package+propagated-inputs): New procedure.
(packages->transitive-inputs, packages+propagated-inputs): Remove.

* tests/guix-environment.sh: Add test with FINDUTILS-BOOT0.
* guix/import/pypi.scm (python->package-name, maybe-inputs, compute-inputs,
guess-requirements): New procedures.

it to determine whether PACKAGE is GNU.
A Cabal package is allowed to declare an "empty" library, in an
otherwise executable-only package, for the purpose of allowing Cabal
to use it as a dependency for other packages. See e.g. hspec-discover.
* guix/build/haskell-build-system.scm (register): Unconditionally call
setup script with "register", and install any config file generated.
A package may be listed in the manifest inputs multiple times. Avoid
copying ghc *.conf files twice by deleting duplicates.
* guix/profiles.scm (ghc-package-cache-file)[conf-files]: Delete
duplicate manifest inputs before copying conf files.
This avoids having 'find-files' report warnings about searching in
non-existent directories.
* guix/profiles.scm (ghc-package-cache-file)[conf-files]: Only search
for *.conf files if the search directory exists.
* guix/scripts/build.scm (package-with-source)[tarball-base-name]: Gracefully
handle file names that lack an extension.

'loop'. When entering a sub-directory, use the current directory's latest
release as 'result'. This fixes the code for 'gnu-pw-mgr' and 'sharutils'.
* guix/scripts/lint.scm (call-with-accumulated-warnings): New procedure.
(with-accumulated-warnings): New macro.
(check-source): Add 'try-uris' and use it. Emit warnings only upon
failure.

(find-among-inputs): ... this. Check whether INPUT is a package before
calling 'package-name'. Fixes a regression introduced in b04af0e.
* guix/monads.scm (foldm, mapm, anym): Change to take a list of regular
values as is customary.
* tests/monads.scm ("mapm", "anym"): Adjust accordingly.
Suggested by 宋文武 <iyzsong@gmail.com>.
* guix/profiles.scm (ghc-package-cache-file): Return a monadic #f, not just
#f, when MANIFEST contains no GHC package.
(profile-derivation): Do not filter based on the return value of HOOK;
instead filter based on the value of items in EXTRAS.
The effect is visible on commands like:
guix build -e '(+ 2 "foo")'
guix build -e '()'
* guix/ui.scm (read/eval): Change handler to properly report syntax errors and

* doc/guix.texi (Invoking guix package): Document it.
This fixes a bug whereby 'guix package -i gcc-toolchain' would fail in
'build-profile'. This is because in 'gcc-toolchain', etc/ is a symlink,
and so the 'scandir' call in 'unsymlink' would return #f instead of
returning a list.
Reported by Andreas Enge <andreas.enge@inria.fr>.
* guix/build/profiles.scm (ensure-writable-directory)[unsymlink]: Append
"/" to TARGET before calling 'scandir'.

Add (guix build profiles) to the #:modules argument.
Previously, code using directly (guix build download) was still affected
by <http://bugs.gnu.org/15368>. This includes source derivations, the
'guix download' command, and (guix gnu-maintenance).
'guix substitute' was unaffected since it used (guix http-client), which
already had the fix.
* guix/http-client.scm (open-socket-for-uri): Remove.
(http-fetch): Remove #:buffered? argument to 'open-socket-for-uri';
use 'setvbuf' instead.
* guix/scripts/substitute.scm (fetch): Likewise.
* guix/build/download.scm (open-socket-for-uri): New procedure, taken
from guix/http-client.scm, but without the #:buffered? parameter.
* guix/search-paths.scm (search-path-definition): New procedure.
* guix/scripts/environment.scm (for-each-search-path): Rename to...
(evaluate-input-search-paths): ... this. Remove 'proc' and 'pure?'
parameters, and return directly the list of search-path/value pairs.
(create-environment): Use 'for-each' and 'evaluate-input-search-paths'
instead of 'for-each-search-path'.
(show-search-paths): Use 'for-each', 'search-path-definition', and
'evaluate-search-paths' instead of 'for-each-search-path'.
This allows 'guix environment' to correctly handle non-directory
and/or pattern search-path specifications, such as that for
'XML_CATALOG_FILES'.
* guix/scripts/environment.scm (for-each-search-path): Use
'evaluate-search-paths' instead of 'search-path-as-list' & co.
* guix/scripts/package.scm (evaluate-search-paths): New procedure, with
most of the code formerly in 'search-path-environment-variables'.
(search-path-environment-variables): Use it.

plus 'package-native-search-paths'.
* tests/profiles.scm ("profile-manifest, search-paths"): New test.
* guix/serialization.scm (read-maybe-utf8-string): Use
'set-port-encoding!' and 'set-port-conversion-strategy!' instead of
setting '%default-port-encoding' and
'%default-port-conversion-strategy'. This accounts for Guile commit
d574d96, which changes bytevector input ports to use ISO-8859-1.
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'.
Partly fixes <http://bugs.gnu.org/20402>.
Reported by Joshua Randall <jcrandall@alum.mit.edu>.
* guix/build/download.scm (open-connection-for-uri): Rewrite to be a
small wrapper around 'open-socket-for-uri'. This procedure was
initially introduced in d14ecda to work around the lack of NSS modules
during bootstrap but that has become unnecessary since 0621349, which
introduced a bootstrap Guile that uses static NSS modules (from commit
d3b5972.)
On Guile >= 2.0.10, this allows the 'http_proxy' environment variable
to be used.
* guix/build-system/cmake.scm (cmake-build): Add #:validate-runpath?
parameter and pass it to BUILDER.

'package-transitive-supported-systems'.
* 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".

phase takes care of copying files.
* guix/build/haskell-build-system.scm (configure): Add '--libsubdir' flag.
