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.
(build-profile): Use them.
* 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.
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
that don't pass 'file-exists?'.
(patch-generated-file-shebangs): Likewise.
* guix/build/gremlin.scm (expand-variable, expand-origin): New
procedures.
(validate-needed-in-runpath): Map 'expand-origin' to the RUNPATH field
of DYNINFO.
* tests/gremlin.scm ("expand-origin"): New test.
* 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.
* 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? ...).
Emit a warning when RUNPATH file names that do not match
'store-file-name?'. Change format of error message to begin with file
name.
* guix/build/utils.scm (store-file-name?): New procedure.
