The `install' phase of the emacs-build-system contained default arguments
duplicated from the host side `emacs-build' procedure. This change factorizes
them so that:
1. They are not duplicated.
2. They can be reused and extended easily when defining emacs packages.

variables.

The compress-documentation phase was breaking recursive symbolic links used
for manuals, which was made visible by the `find-files' call in the recently
added `manual-database' profile hook. See <http://bugs.gnu.org/26771>.

[points-to-symbolic-link?]: New procedure.

".el" extension from file name before splitting to name and version.

* guix/build/pull.scm (depends-on-guile-ssh?, all-scheme-files): New
procedures.
(build-guix): Show the output of (version). Use the above procedures.
Filter out files that match 'depends-on-guile-ssh?' when (ssh session)

This allows us to download from site such as
<https://fusionforge.int-evry.fr> where the server does not recognize
the server name passed via the 'server_name' extension.

that cannot happen.
* guix/build/download.scm (open-connection-for-uri): Add note about
same-named binding in Guile 2.2.0.

* guix/scripts/lint.scm: Likewise.

(build): Also build libraries, not just applications.
(file-sha256): New variable.
(generate-checksums): New variable. Export it.
(touch): New variable.
(install): Generate checksums so Cargo accepts the package.
Before that, something like:
(call-with-container
(lambda ()
(match (primitive-fork)
…)))
would hang in 'primitive-fork' as the child process (the one started in
the container) would try to pthread_join the finalization thread in
'stop_finalization_thread' in libguile, not knowing that this thread is
nonexistent.
* guix/build/syscalls.scm (%set-automatic-finalization-enabled?!): New
procedure.
(without-automatic-finalization): New macro.
(clone): Wrap PROC call in 'without-automatic-finalization'.
* guix/build/syscalls.scm (define-bits): Do not define NAMES... as
top-level variables since that prevents literal matches in 2.2.
Instead, determine constant values at expansion time.
In glibc-2.25 a dependency on "linux/falloc.h" was added.
This also reverts commit 8f8f250bdc
which is no longer needed. This commit was not compatible with
the glibc version Hurd is using. See
<https://lists.gnu.org/archive/html/guix-devel/2017-02/msg01046.html>
* guix/build/make-bootstrap.scm (make-stripped-libc): Copy "falloc.h"

* gnu/packages/patches/glibc-bootstrap-system.patch: Remove part
that touches fcntl-linux.h.
Problem reported by Andreas Enge <andreas@enge.fr>.
It doesn't make sense to run non-test executables (which is what "dub run"
would do).
The "check" function already invokes "dub test" and that's enough.
* guix/build/dub-build-system.scm (build): Remove "dub run" invocation.
* gnu/build/activation.scm (make-file-writable): Move this to ...
* guix/build/utils.scm (make-file-writable): ... here. Export it.
* guix/build/gnu-build-system.scm (strip): Use it.
This avoids a situation where the "debug" output would contain separate
(and different) .debug files for "libfoo.so" and "libfoo.so.0.0", even
though "libfoo.so" is actually a symlink to "libfoo.so.0.0".
* guix/build/gnu-build-system.scm (strip): Remove 'file-exists?' call in
'for-each' lambda. Pass a predicate to 'find-files' to restrict the
result to regular files.
This adds support for single-entry search paths.

* guix/build-system/python.scm (python-build): New keyword argument
"#:use-setuptools?", defaulting to #t.
* guix/build/python-build-system.scm (call-setup-py): New positional
parameter "use-setuptools?". If false, do not use the shim-wrapper
for addin setuptools. (build, check): accept keyword-
parameter, and pass to call-setuppy. (install): same; if
"use-setuptools?" is false, do not use options "--root" and
"--single-version-externally-managed" for setup.py.
* doc/guix.texi (Build Systems): Document it.
This is needed for packages using "distutils" instead of "setuptools" since
the former does not understand the "--single-version-externally-managed"
flag. Also export __file__ since it will be unset when setup.py is called from
python "exec".
* guix/build/python-build-system.scm (call-setuppy): extend "python setup.py"
call to import setuptools, export __file__, and call setup.py from
setuptools python environment.
Co-Authored-By: Hartmut Goebel <h.goebel@crazy-compilers.com>
This requires setuptools to be installed together with python, which is
the case for Python 3 anyway and which we do for our build of Python 2
(see last commit).
* guix/build/python-build-system.scm (install): Add
"--single-version-externally-managed" and "--root=/" to params to be
passed to call-setuppy. Remove thus needless manipulation of
PYTHONPATH. Remove now unused argument "inputs".
The python-build-system uses phases the build and install, but not
configure. So the old comment was plain wrong since Sept. 2013, when the build
phase has been added.

This fixes a bug whereby the choice between stripping 'libfoo.so.0.1.2'

(install): Remove files containing non-reproducible elements. Print when each

faster grafting. Use binary I/O instead of textual I/O. Replace
'mapping' argument (an alist) with 'replacement-table' (a vhash).

'%default-port-encoding' to #f, since we now use binary I/O.
(define-inline, hash-length): New macros.
(nix-base32-char?): New variable.
Resolved conflicts:
