* guix/build/graft.scm (rewrite-directory)[rewrite-leaf]: Change to take
a single parameter. Add call to 'lstat'. Factorize result of
'destination'.
Use 'find-files' instead of 'file-system-fold'.
* guix/build/download.scm (open-socket-for-uri): Always pass
AI_ADDRCONFIG to 'getaddrinfo' as recommended in the fine Guile
manual.
* guix/ftp-client.scm (ftp-open): Ditto.
* guix/build/download.scm (ensure-uri): New procedure.
(current-http-proxy): New variable.
(open-socket-for-uri): Copy from Guile commit aaea5b2, but add #:timeout
parameter and use 'connect*' instead of 'connect'.
(open-connection-for-uri): Add #:timeout parameter and pass it to
'open-socket-for-uri'.
Benefits include: 'guix environment' more useful for ghc libraries, more
useful 'guix package --search-paths' for installed ghc libraries, cleaner
package recipes: no longer need to propagate runtime package dependencies.
* guix/build/haskell-build-system.scm (configure): Unset GHC_PACKAGE_PATH
around cabal configure.
(make-ghc-package-database): Use pattern directory search.
(register): Install complete package database for the current package.
* gnu/packages/haskell.scm (ghc): Add native-search-paths field.
For Cabal packages with "build-type: Configure", a configure shell
script is run to set up build parameters. These scripts need the
CONFIG_SHELL environment variable to be set to function properly.
* guix/build/haskell-build-system.scm (configure): Set CONFIG_SHELL if
necessary.
Fixes <http://bugs.gnu.org/21694>.
* guix/build/syscalls.scm (clone): Change 'syscall' parameter types to
LONG, UNSIGNED-LONG, or '*; make sure it has 6 parameters. Adjust
caller accordingly.
Fixes a regression introduced in a8be7b9a.
* guix/build/download.scm (store-path-abbreviation): Return STORE-PATH
if it's not an actual store path. Fixes an out-of-range exception
when running tests/substitute.scm and tests/store.scm.
* guix/build/download.scm
(string-pad-middle): Allow resulting padded string to overflow.
(store-url-abbreviation): Remove unnecessary procedure.
(progress-proc): Use BASENAME as default for parameter 'abbreviation'.
(url-fetch): Display extra newlines for readability.
Fixes a regression introduced in b7c7c03eb5.
* guix/build/emacs-build-system.scm (package-name-version->elpa-name-version):
Remove unused 'name' binding. Do not abuse 'strip-store-file-name' to
remove the "emacs-" prefix, which worked before b7c7c03eb5 but not after.
* guix/build/download.scm
(string-pad-middle, store-url-abbreviation, store-path-abbreviation):
New procedures.
(progress-proc): Add #:abbreviation parameter and use it. Generate a
better indeterminate progress string.

Previously, the Ruby build system only knew how to work with gem archives,
which made it difficult to build unreleased gems from a Git repository or
released gems in tarball form.
* gnu/build/ruby-build-system.scm (gnu:unpack, gem-archive?): New procedures.
(unpack): Use GNU build system unpack phase for non-gem sources.
(build): Rebuild the gemspec iff the source is a gem archive.
* guix.texi ("ruby-build-system"): Mention that tarballs and directories are
acceptable.
* guix/build/download.scm (seconds->string): New function.
(byte-count->string): New function.
(progress-bar): New function.
(throughput->string): Remove function.
(progress-proc): Display base file name, elapsed time, and progress bar.

The intent is to make 'clone' behave a lot more like 'primitive-fork', which
calls clone(2) with SIGCHLD, CLONE_CHILD_CLEARTID, and CLONE_CHILD_SETTID
flags. Notably, running 'clone' at the REPL without these flags would break
the REPL beyond repair.
* guix/build/syscalls.scm (CLONE_CHILD_CLEARTID, CLONE_CHILD_SETTID): New
variables.
* gnu/build/linux-container.scm (namespaces->bit-mask): Add
CLONE_CHILD_CLEARTID and CLONE_CHILD_SETTID to bit mask.
Having the hash of the source gem in the source directory file name proved to
be problematic when running the test suite for the 'pg' gem that creates
UNIX-domain sockets in the source directory and exceeded the 108 character
limit on GNU/Linux systems.
* guix/build/ruby-build-system.scm (unpack): Rename unpacked gem directory to
"gem".
* guix/build/utils.scm (strip-store-file-name): New procedure.
* guix/build/emacs-build-system.scm (store-directory->name-version):
Remove. Update callers to use 'strip-store-file-name'.
* gnu/packages/gcc.scm (make-libstdc++-doc)[arguments]: Use
'strip-store-file-name' instead of 'string-drop'.
* guix/build/gnu-build-system.scm (gnu-build)[elapsed-time]: New
procedure.
Use it, and use (current-time time-monotonic) instead
of (gettimeofday). Show one digit after the comma for the elapsed
time.
On systems with a glibc prior to 2.14, the 'setns' function is not available.
Thanks to Eric Bavier for reporting the issue.
* guix/build/syscalls.scm (setns): Wrap with 'false-if-exception'.
Based on discussions with Rohan Prinja <rohan.prinja@gmail.com>.
* guix/build/syscalls.scm (<interface>): New record type.
(write-interface, values->interface, unfold-interface-list,
network-interfaces, free-ifaddrs): New procedures.
(ifaddrs): New C struct.
(%struct-ifaddrs-type, %sizeof-ifaddrs): New macros.
* tests/syscalls.scm ("network-interfaces returns one or more interfaces",
"network-interfaces returns \"lo\""): New tests.
* guix/build/syscalls.scm (alignof*, align): New macros.
(write-types, read-types): Use 'align' to compute the actual offset to
read/write a value of TYPE0.
* guix/build/syscalls.scm (PF_PACKET, AF_PACKET): New variables.
(read-socket-address): Make 'index' optional. Return (vector FAMILY) when
FAMILY is neither AF_INET nor AF_INET6.
* guix/build/syscalls.scm (read-types): Add RETURN and VALUES parameters.
(define-c-struct): Add WRAP-FIELDS parameter and pass it to 'read-types'.
(sockaddr-in, sockaddr-in6): Add first argument that uses
'make-socket-address'.
(read-socket-address): Remove 'match' on the result of 'read-sockaddr-in'
and 'read-sockaddr-in6'.
* guix/build-system/gnu.scm (gnu-build, gnu-cross-build): Accept #:build
keyword argument. Pass it to 'gnu-build' on the build side.
* guix/build/gnu-build-system.scm (configure): Accept #:build keyword
argument. Unless it is false, pass --build to configure.
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.
* guix/build/profiles.scm (ensure-writable-directory): Export.
* guix/profiles.scm (gtk-icon-themes)[build]: Remove '@@' form and use (guix
build profiles).
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.
Reported by 宋文武 <iyzsong@gmail.com>.
* guix/build/profiles.scm (build-etc/profile,
ensure-writable-directory): New procedures.

* 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.
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.
Fixes <http://bugs.gnu.org/20081>.
Reported by Tomáš Čech <tcech@suse.cz>.
* guix/build/gnu-build-system.scm (patch-source-shebangs): Remove files

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.
* guix/build/haskell-build-system.scm (make-ghc-package-database, register):
Aligh location of 'package.conf.d' directory with '--libsubdir' flag.
Fixes <http://bugs.gnu.org/20081>.
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'.
* guix/build/gremlin.scm (validate-needed-in-runpath)[runpath]:
Add (filter absolute-file-name? ...).

'store-file-name?'. Change format of error message to begin with file
name.

* gnu/packages/cmake.scm (cmake)[native-search-paths]: New field.
* guix/build/cmake-build-system.scm (configure): Drop environment variables
CMAKE_LIBRARY_PATH and CMAKE_INCLUDE_PATH.
* guix/build/gnu-build-system.scm (gnu-build): Leave
%DEFAULT-PORT-CONVERSION-STRATEGY unchanged when 'string->bytevector'
fails to convert to ISO-8859-1. This is an attempt to work around the
build failures at <http://hydra.gnu.org/build/263002>.
Suggested by Mark H Weaver.
* guix/build/gnu-build-system.scm (gnu-build): Set
%DEFAULT-PORT-CONVERSION-STRATEGY to 'error.
* guix/packages.scm (patch-and-repack)[builder]: Likewise.

This is the case for Guile 2.0.6 or earlier.
Fixes <http://bugs.gnu.org/19840>.
Reported by Ricardo Wurmus <rekado@elephly.net>.

reflect that we are dealing with more types of data and not only with
schemas. Add handling of GIO modules.
* guix/build-system/glib-or-gtk.scm (lower): Import the 'bin' output of GLib
instead of 'out'. This was an error since we need the program
'glib-compile-schemas'. Update the description.
* guix/build/utils.scm (patch-/usr/bin/file): New procedure.
* guix/build/gnu-build-system.scm (patch-usr-bin-file): Rewrite using
it. Patch all the files returned by 'find-files' that are executable.

for 'extension/configure'.
Fixes <http://bugs.gnu.org/18895>.
* guix/build/gnu-build-system.scm (patch-shebangs): Add #:inputs
parameter. Remove 'bindirs'. Add 'bin-directories',
'output-bindirs', and 'input-bindirs'. Use them instead of (getenv
"PATH") to as the argument to 'patch-shebang'.
This is a followup to 856ae5e. See <http://hydra.gnu.org/build/180506>
for an example of build failure.
