This fixes the build on Python 3.9.
* gnu/packages/version-control.scm (mercurial): Update to 5.6.1. Delete
trailing #t.
[phases]{check}: Remove the "test-transaction-rollback-on-sigpipe.t" test
file and add a comment.
GConf has been deprecated for a while. This change removes GConf (and
thus ORBit) from the closure of GNOME.
* gnu/packages/ibus.scm (ibus)[inputs]: Remove GCONF.
* gnu/packages/python-xyz.scm (python-isort): Update to 5.7.0.
[source]: Delete checked in binary wheels in a snippet.
[arguments]: New field.
[phases]: Replace the build and install phases, implementing the basics of a
PEP 517 build system.
{check}: Override phase.
{install-example-plugins}: New phase.
[native-inputs]: Remove python-mock. Add git-minimal, python-black,
python-colorama, python-hypothesmith, python-libcst-minimal,
python-poetry-core, python-pylama, python-pypa-build and python-pytest-mock.
[home-page]: Update home page.
* gnu/packages/python-xyz.scm (python-libcst-minimal): New variable.
(python-libcst): Add a tests? argument to the check phase override and strip
trailing #t.
Python 3.9 implemented PEP 615 (<)https://www.python.org/dev/peps/pep-0615/>),
which relies on either a compiled time default value or the PYTHONTZPATH
environment variable to find the system tzdata database.
* gnu/packages/python.scm (python-3.9)[native-search-paths]: Add a new search
path specification for PYTHONTZPATH.
Based on a reading of the install_requires field of its setup.cfg file.
* gnu/packages/check.scm (python-pytest)[native-inputs]: Move
python-iniconfig...
[propagated-inputs]: ... to here. Add python-toml. Remove
python-atomicwrites, apparently only required on the win32 platform.
This follows commit b5ccc6cc9a, which updated python-pytest to version 6 and
removed the python-pytest-6 variable.
* gnu/packages/python-check.scm (python-mypy)
[native-inputs]: Rename python-pytest-6 to python-pytest.
* gnu/packages/python-xyz.scm (python-pep517): Inherit from
python-pep517-bootstrap. Remove the inherited common fields.
(python-poetry-core, python-wheel)
(python-toml): Move to ...
* gnu/packages/python-build.scm: ... here, a new module.
(python-pep517-bootstrap): New package.
* gnu/local.mk (GNU_SYSTEM_MODULES): Register the new module.
Fixes a regression introduced in
959a397d22, whereby directory names in
'libzstd.pc' would lack a slash after $prefix.
* gnu/packages/compression.scm (zstd)[arguments]: In
'adjust-library-locations' phase, add trailing slash for $prefix in .pc
file.
Previously, it would error out, not finding its Perl modules, and later not
finding config.guess. This utility is useful to query the local TeX Live
package database (texlive.tlpdb).
(texlive-bin)[inputs]{config}: New input.
[phases]{postint}: Add a symlink to the 'config.guess' script. Patch the
tlmgr.pl script so that it can find its Perl modules and other resources.
This allows the sources to processed normally by the other phases such as
patch-source-shebangs.
* gnu/packages/tex.scm (texlive-bin)[arguments]: Specify #:modules.
[phases]{unpack-texlive-extra, unpack-texlive-scripts}: New phases.
{postint}: Move the unpacking of the texlive-extra and texlive-scripts inputs
to the above newly added phases. The installation of these extra directories
now simply uses copy-recursively.
