Fixes <http://bugs.gnu.org/20791>.
Reported by Benz Schenk <benz.schenk@uzh.ch>.
* gnu/system/install.scm (installation-services): Add #:rules argument for
'udev-service'.
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.
Pass #:recursive? #t to 'download-to-store'.
* guix/download.scm (download-to-store): Add #:recursive? parameter and pass
it to 'add-to-store'.
* doc/guix.texi (Invoking guix build): Add an example of --with-source with a
directory.
* guix/scripts/environment.scm (guix-environment): Call 'parse-command-line'
outside of 'with-store'. This allows things like --help to run even if the
daemon is not running.
Fixes <http://bugs.gnu.org/19044>.
* nix/guix-register/guix-register.cc (register_validity): Change the (optimize
&& prefix.empty ()) condition to just (optimize). Change settings.nixStore
around the loop. Prepend PREFIX to the argument passed to 'optimisePath'.
* tests/guix-register.sh: Use 'guix-register -p' with duplicate files, and
make sure they are deduplicated on the target. Adjust existing tests.
Fixes <http://bugs.gnu.org/20722>.
Reported by Eric Bavier <ericbavier@openmailbox.org>.
* guix/scripts/system.scm (copy-item): Check whether DEST exists and remove it
if it does.
* gnu/build/install.scm (populate-root-file-system): Delete system-1-link
under TARGET, not under /. Use 'catch' and check for EEXIST instead of
(false-if-exception (delete-file ...)).
* guix/import/cabal.scm: New file.
* guix/import/hackage.scm: Update to use the new Cabal parsing module.
* tests/hackage.scm: Update tests.
* guix/scripts/import/hackage.scm: Add new '--cabal-environment' and '--stdin'
options.
* doc/guix.texi: ... and document them.
* Makefile.am (MODULES): Add 'guix/import/cabal.scm',
'guix/import/hackage.scm' and 'guix/scripts/import/hackage.scm'.
(SCM_TESTS): Add 'tests/hackage.scm'.
Suggested by Thomas Schwinge <thomas@codesourcery.com>.
* gnu/system/install.scm (self-contained-tarball): Remove
"/root/.guix-profile" from the 'tar' arguments.
* doc/guix.texi (Binary Installation): Add a step to create
~root/.guix-profile.
Suggested by Federico Beffa <beffa@fbengineering.ch>.
* guix/monads.scm (bind-syntax): New macro.
(with-monad): Use it instead of 'identifier-syntax'.
* tests/monads.scm (">>= with more than two arguments"): New test.
* doc/guix.texi (The Store Monad): Explain that there can be several MPROC.
Add an example.
