* tests/guix-package.sh: Adjust existing tests and add new test.
* 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'.
* tests/profiles.scm ("etc/profile when etc/ is a symlink"): New test.
* guix/scripts/publish.scm (show-help, %options): Add --listen.
(getaddrinfo*): New procedure.

the actual address.
* doc/guix.texi (Invoking guix publish): Document it.
* guix/scripts/publish.scm (show-help): Add --user.
(%options): Likewise.
(run-publish-server): Change 'port' parameter to 'socket'. Pass
#:socket instead of #:addr and #:port to 'run-server'. Update caller
accordingly.

* tests/profiles.scm ("etc/profile when etc/ already exists"): New test.
* guix/build/profiles.scm: New file.
* Makefile.am (MODULES): Add it.
* guix/profiles.scm (profile-derivation)[builder]: Call out to
'build-profile'.
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.
* guix/scripts/package.scm (user-friendly-profile): New procedure.
(search-path-environment-variables): Remove 'profile' local variable.
(display-search-paths): Explicitly call 'user-friendly-profile' for
the argument to 'search-path-environment-variables'.
(guix-package)[process-query]: Likewise.
Discussed in <http://bugs.gnu.org/20255>.
* guix/packages.scm (sexp->search-path-specification): New variable.

(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.
* 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.
* guix/build-system/glib-or-gtk.scm (glib-or-gtk-build): Likewise.

'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".
* doc/guix.texi (Invoking guix refresh): Add an example.
Fixes a regression whereby haskell-build-system was using an incomplete
module list.
* guix/build-system/haskell.scm (%haskell-build-system-modules): New

(the default), add the result of 'ghc-package-cache-file' to 'inputs'.

#:ghc-package-cache? to 'profile-generation'.
* tests/packages.scm ("--search-paths with pattern"): Likewise.
* tests/profiles.scm ("profile-derivation"): Likewise.
* guix/build/haskell-build-system.scm (%standard-phases): move 'haddock phase
before 'install phase.
* guix/build/haskell-build-system.scm (haddock): Simplify it as the 'install
phase takes care of copying files.
* guix/build/haskell-build-system.scm (configure): Add '--libsubdir' flag.
Fix use of '--extra-include-dirs' and '--extra-lib-dirs' flags. Use 'doc',
'bin' and 'lib' outputs if they are defined.

Reported by Tomáš Čech <sleep_walker@suse.cz>.
* guix/build/utils.scm (find-files): Add #:stat parameter. Pass it as
last argument to 'file-system-fold'.

tests.
* doc/guix.texi (G-Expressions): Mention local files early. Document
'local-file'. Update 'text-file*' documentation.
Before that, "guix build qt", when only qt itself is missing, would lead
'substitution-oracle' to call 'substitutable-paths' with 318 items.
Now, this is down to 6 items, because it doesn't ask about prerequisites
that are already valid.
* guix/derivations.scm (substitution-oracle)[valid-input?,
dependencies]: New procedures.
Use 'dependencies' and remove call to 'remove'.
* guix/derivations.scm (valid-derivation-input?): New procedure.

#:native? and honor it.
[add-reference-inputs]: Distinguish between native gexp inputs, and
non-native gexp inputs. Honor 'native?' field of list inputs.
* tests/gexp.scm ("ungexp + ungexp-native, nested"): New test.
Before that, the 'references' and 'natives' or the outer gexp in an
expression like #~#+#~#$coreutils would include those of the inner
gexp.
* guix/gexp.scm (gexp)[collect-escapes]: Ignore everything below
'ungexp-native' or 'ungexp-native-splicing'.
[collect-native-escapes]: Ignore everything below 'ungexp' or

* guix/packages.scm (%standard-patch-inputs): Use
GLIBC-UTF8-LOCALES-FINAL instead of GLIBC-UTF8-LOCALES.
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'.

#: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".
From now own, (guix packages) depends on (guix gexps); it was the other
way around now. This means that (guix packages) code can use gexps.
* guix/gexp.scm (origin-compiler, package-compiler): Remove.
(default-guile-derivation): New procedure.
(gexp->derivation): Use it instead of 'default-guile' +

CMAKE_LIBRARY_PATH and CMAKE_INCLUDE_PATH.
This fixes a bug whereby uses of 'package-with-python2' at the top-level
