The summary=0D is that the goal of this series is to ensure that the `python` used to=0D run meson is the same `python` used to run Sphinx, tests, and any=0D build-time python scripting we have. As it stands, meson and sphinx (and=0D their extensions) *may* run in a different python environment than the=0D one configured and chosen by the user at configure/build time.=0D =0D The effective change of this series is that QEMU will now=0D unconditionally create a venv at configure-time and will ensure that=0D meson (and sphinx, if docs are enabled) are available through that venv.=0D =0D Some important points as a pre-emptive "FAQ":=0D =0D - This venv is unconditionally created and lives at {build_dir}/pyvenv.=0D =0D - The python interpreter used by this venv is always the one identified=0D by configure. (Which in turn is always the one specified by --python=0D or $PYTHON)=0D =0D - *almost* all python scripts in qemu.git executed as part of the build=0D system, meson, sphinx, avocado tests, vm tests or CI are always=0D executed within this venv.=0D =0D (iotests are not yet integrated; I plan to tackle this separately as a=0D follow-up in order to have a more tightly focused scope on that=0D series.)=0D =0D - It remains possible to build and test fully offline.=0D (In most cases, you just need meson and sphinx from your distro's repo.)= =0D =0D - Distribution packaged 'meson' and 'sphinx' are still utilized whenever=0D possible as the highest preference.=0D =0D - Vendored versions of e.g. 'meson' are always preferred to PyPI=0D versions for speed, repeatability and ensuring tarball builds work=0D as-is offline.=0D =0D (Sphinx will not be vendored, just like it already isn't.)=0D =0D - Missing dependencies, when possible, are fetched and installed=0D on-demand automatically to make developer environments "just work".=0D =0D - Works for Python 3.6 and up, on Fedora, OpenSuSE, Red Hat, CentOS,=0D Alpine, Debian, Ubuntu, NetBSD, OpenBSD, and hopefully everywhere=0D =0D - No new dependencies (...for most platforms. Debian and NetBSD get an=0D asterisk.)=0D =0D - The meson git submodule is unused after this series and can be removed.=0D =0D ... I could write more, and I'm sure there's a few things that need=0D buffing out or changing here and there, but I think it's largely good.=0D =0D So, enjoy!=0D =0D ~js=0D =0D John Snow (22):=0D python: update pylint configuration=0D python: add mkvenv.py=0D mkvenv: add better error message for missing pyexpat module=0D mkvenv: add nested venv workaround=0D mkvenv: add ensure subcommand=0D mkvenv: add diagnose() method for ensure() failures=0D mkvenv: add console script entry point generation=0D mkvenv: work around broken pip installations on Debian 10=0D tests/docker: add python3-venv dependency=0D tests/vm: Configure netbsd to use Python 3.10=0D tests/vm: add py310-expat to NetBSD=0D python: add vendor.py utility=0D configure: create a python venv unconditionally=0D python/wheels: add vendored meson package=0D configure: use 'mkvenv ensure meson' to bootstrap meson=0D qemu.git: drop meson git submodule=0D tests: Use configure-provided pyvenv for tests=0D configure: move --enable-docs and --disable-docs back to configure=0D configure: bootstrap sphinx with mkvenv=0D configure: add --enable-pypi and --disable-pypi=0D configure: Add courtesy hint to Python version failure message=0D mkvenv.py: experiment; use distlib to generate script entry points=0D =0D Paolo Bonzini (5):=0D python: shut up "pip install" during "make check-minreqs"=0D mkvenv: create pip binary in virtual environment=0D Python: Drop support for Python 3.6=0D mkvenv: mark command as required=0D python: bump some of the dependencies=0D =0D docs/about/build-platforms.rst | 2 +-=0D docs/conf.py | 9 -=0D docs/devel/acpi-bits.rst | 6 +-=0D docs/devel/testing.rst | 14 +-=0D docs/meson.build | 2 +-=0D configure | 155 ++--=0D .gitlab-ci.d/buildtest-template.yml | 4 +-=0D .gitlab-ci.d/buildtest.yml | 6 +-=0D .gitmodules | 3 -=0D meson | 1 -=0D meson_options.txt | 2 -=0D python/Makefile | 19 +-=0D python/scripts/mkvenv.py | 858 ++++++++++++++++++=0D python/scripts/vendor.py | 74 ++=0D python/setup.cfg | 27 +-=0D python/tests/flake8.sh | 1 +=0D python/tests/isort.sh | 1 +=0D python/tests/minreqs.txt | 16 +-=0D python/tests/mypy.sh | 1 +=0D python/tests/pylint.sh | 1 +=0D python/wheels/meson-0.61.5-py3-none-any.whl | Bin 0 -> 862509 bytes=0D .../org.centos/stream/8/x86_64/test-avocado | 4 +-=0D scripts/device-crash-test | 2 +-=0D scripts/meson-buildoptions.sh | 3 -=0D scripts/qapi/mypy.ini | 2 +-=0D tests/Makefile.include | 10 +-=0D .../dockerfiles/debian-all-test-cross.docker | 3 +-=0D .../dockerfiles/debian-hexagon-cross.docker | 3 +-=0D .../dockerfiles/debian-riscv64-cross.docker | 3 +-=0D .../dockerfiles/debian-tricore-cross.docker | 3 +-=0D tests/requirements.txt | 7 +-=0D tests/vm/netbsd | 2 +=0D 32 files changed, 1108 insertions(+), 136 deletions(-)=0D delete mode 160000 meson=0D create mode 100644 python/scripts/mkvenv.py=0D create mode 100755 python/scripts/vendor.py=0D create mode 100644 python/wheels/meson-0.61.5-py3-none-any.whl=0D =0D -- =0D 2.40.0=0D =0D
