Subject: 75/166: gnu: python-scipy: Update to 1.8.0 and enable parallel build.
Date: Tue, 19 Apr 2022 09:12:22 -0400 (EDT)

apteryx pushed a commit to branch wip-ipython+polyglossia
in repository guix.

commit 549f619d3deccfab14f8387f79192caafc29fb13
Author: Maxim Cournoyer <maxim.cournoyer@gmail.com>
AuthorDate: Wed Apr 6 22:24:48 2022 -0400

    gnu: python-scipy: Update to 1.8.0 and enable parallel build.
    
    * gnu/packages/python-science.scm (python-scipy): Update to 1.8.0.
    [modules]: New argument.
    [phases]{disable-broken-tests}: Delete phase.
    {configure-openblas}: Streamline configuration template.
    {parallelize-build}: New phase.
    {install-doc}: Move before 'check phase.  Remove now extraneous
    'add-installed-pythonpath' call.  Remove the SPHINXBUILD and PYVER Make
    variables, as well as conf.py patching.  Provide SPHINXOPTS to build doc in
    parallel.  Simply recursively copy the 'html' output directory to install 
the
    doc.
    {check}: Remove extraneous INPUTS and OUTPUTS arguments.  Start tests with 
the
    'runtests.py' launcher, which accepts a '-j' argument to run the tests in
    parallel.
    [native-inputs]: Sort inputs.  Add python-pytest-xdist and
    python-threadpoolctl.
    [home-page]: Update.
