2023-07-07python: bump minimum requirements so they are compatible with 3.12Paolo Bonzini
There are many Python 3.12 issues right now, but a particularly problematic one when debugging them is that one cannot even use minreqs.txt in a Python 3.12 virtual environment to test with locked package versions. Bump the mypy and wrapt versions to fix this, while remaining within the realm of versions compatible with Python 3.7. This requires a workaround for a mypy false positive qemu/qmp/qmp_tui.py:350: error: Non-overlapping equality check (left operand type: "Literal[Runstate.DISCONNECTING]", right operand type: "Literal[Runstate.IDLE]") [comparison-overlap] where mypy does not realize that self.disconnect() could change the value of self.runstate.

2023-06-06mkvenv: always pass locally-installed packages to pipPaolo Bonzini
Let pip decide whether a new version should be installed or the current one is okay. This ensures that the virtual environment is updated (either upgraded or downgraded) whenever a new version of a package is requested. The hardest part here is figuring out if a package is installed in the venv (which also has to be done twice to account for the presence of either setuptools in Python <3.8, or importlib in Python >=3.8).

2023-05-31python/machine: use connect-based interface for existing socketsJohn Snow
Instead of using accept() with sockets (which uses open_with_socket()), use calls to connect() to utilize existing sockets instead.

2023-05-19mkvenv: pass first missing package to diagnose()Paolo Bonzini
If sphinx is present but the theme is not, mkvenv will print an inaccurate diagnostic: ERROR: Could not find a version that satisfies the requirement sphinx-rtd-theme>=0.5.0 (from versions: none) ERROR: No matching distribution found for sphinx-rtd-theme>=0.5.0 'sphinx>=1.6.0' not found: • Python package 'sphinx' version '5.3.0' was found, but isn't suitable. • mkvenv was configured to operate offline and did not check PyPI.

2023-05-19mkvenv: replace distlib.database with importlib.metadata/pkg_resourcesPaolo Bonzini
importlib.metadata is just as good as distlib.database and a bit more battle-proven for "egg" based distributions, and in fact that is exactly why mkvenv.py is not using distlib.database to find entry points: it simply does not work for eggs. The only disadvantage of importlib.metadata is that it is not available by default before Python 3.8, so we need a fallback to pkg_resources (again, just like for the case of finding entry points). Do so to fix issues where incorrect egg metadata results in a JSONDecodeError. While at it, reuse the new _get_version function to diagnose an incorrect version of the package even if importlib.metadata is not available. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

It is a good time to do so, before Python packages start dropping support for Python 3.7 as well! The new mypy is also a bit smarter about which packages are actually being used, so remove the now-unnecessary sections from setup.cfg.

2023-05-18Python: Drop support for Python 3.6Paolo Bonzini
Python 3.6 was EOL 2021-12-31. Newer versions of upstream libraries have begun dropping support for this version and it is becoming more cumbersome to support. Avocado-framework and qemu.qmp each have their own reasons for wanting to drop Python 3.6, but won't until QEMU does. Versions of Python available in our supported build platforms as of today, with optional versions available in parentheses: openSUSE Leap 15.4: 3.6.15 (3.9.10, 3.10.2) CentOS Stream 8: 3.6.8 (3.8.13, 3.9.16) CentOS Stream 9: 3.9.13 Fedora 36: 3.10 Fedora 37: 3.11 Debian 11: 3.9.2 Alpine 3.14, 3.15: 3.9.16 Alpine 3.16, 3.17: 3.10.10 Ubuntu 20.04 LTS: 3.8.10 Ubuntu 22.04 LTS: 3.10.4 NetBSD 9.3: 3.9.13* FreeBSD 12.4: 3.9.16 FreeBSD 13.1: 3.9.16 OpenBSD 7.2: 3.9.16 Note: Our VM tests install 3.9 explicitly for FreeBSD and 3.10 for NetBSD; the default for "python" or "python3" in FreeBSD is 3.9.16. NetBSD does not appear to have a default meta-package, but offers several options, the lowest of which is 3.7.15. "python39" appears to be a pre-requisite to one of the other packages we request in tests/vm/netbsd. pip, ensurepip and other Python essentials are currently only available for Python 3.10 for NetBSD. CentOS and OpenSUSE support parallel installation of multiple Python interpreters, and binaries in /usr/bin will always use Python 3.6. However, the newly introduced support for virtual environments ensures that all build steps that execute QEMU Python code use a single interpreter. Since it is safe to under our supported platform policy, bump our minimum supported version of Python to 3.7. Signed-off-by: John Snow <jsnow@redhat.com> Reviewed-by: Daniel P.

2023-05-18python/wheels: add vendored meson packageJohn Snow
In preference to vendoring meson source, vendor a built distributable ("bdist" in python parlance). This has some benefits: (1) We can get rid of a git submodule, (2) Installing built meson into a venv doesn't require any extra dependencies (the python "wheel" package, chiefly.) (3) We don't treat meson any differently than we would any other python package (we install it, end of story, done.) (4) All future tarball *and* developer checkouts will function offline; No git or PyPI connection needed to fetch meson. Note that because mkvenv prefers vendored packages to PyPI, as mkvenv is currently written we will never consult PyPI for meson. (Do keep in mind that your distribution's meson will be preferred above the vendored version, though.) ``` jsnow@scv ~/s/q/python (python-configure-venv)> python3 scripts/vendor.py pip download --dest /home/jsnow/src/qemu/python/wheels --require-hashes -r /tmp/tmpvo5qav7i Collecting meson==0.61.5 Using cached meson-0.61.5-py3-none-any.whl (862 kB) Saved ./wheels/meson-0.61.5-py3-none-any.whl Successfully downloaded meson ``` Signed-off-by: John Snow <jsnow@redhat.com> Message-Id: <20230511035435.734312-17-jsnow@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2023-05-18python: add vendor.py utilityJohn Snow
This is a teeny-tiny script that just downloads any packages we want to vendor from PyPI and stores them in qemu.git/python/wheels/. If I'm hit by a meteor, it'll be easy to replicate what I have done in order to udpate the vendored source. We don't really care which python runs it; it exists as a meta-utility with no external dependencies and we won't package or install it. It will be monitored by the linters/type checkers, though; so it's guaranteed safe on python 3.6+.

This is a workaround intended for Debian 10, where the debian-patched pip does not function correctly if accessed from within a virtual environment. We don't support Debian 10 as a build platform any longer, though we do still utilize it for our build-tricore-softmmu CI test.

2023-05-18mkvenv: use pip's vendored distlib as a fallbackJohn Snow
distlib is usually not installed on Linux distribution, but it is vendored into pip. Because the virtual environment has pip via ensurepip, we can piggy-back on pip's vendored version. This could break if they move our cheese in the future, but the fix would be simply to require distlib. If it is debundled, as it is on msys, it is simply available directly.

2023-05-18mkvenv: add console script entry point generationJohn Snow
When creating a virtual environment that inherits system packages, script entry points (like "meson", "sphinx-build", etc) are not re-generated with the correct shebang. When you are *inside* of the venv, this is not a problem, but if you are *outside* of it, you will not have a script that engages the virtual environment appropriately. Add a mechanism that generates new entry points for pre-existing packages so that we can use these scripts to run "meson", "sphinx-build", "pip", unambiguously inside the venv.

2023-05-18mkvenv: add --diagnose option to explain "ensure" failuresJohn Snow
This is a routine that is designed to print some usable info for human beings back out to the terminal if/when "mkvenv ensure" fails to locate or install a package during configure time, such as meson or sphinx. Since we are requiring that "meson" and "sphinx" are installed to the same Python environment as QEMU is configured to build with, this can produce some surprising failures when things are mismatched. This method is here to try and ease that sting by offering some actionable diagnosis.

2023-05-18mkvenv: add ensure subcommandJohn Snow
This command is to be used to add various packages (or ensure they're already present) into the configure-provided venv in a modular fashion. Examples: mkvenv ensure --online --dir "${source_dir}/python/wheels/" "meson>=0.61.5" mkvenv ensure --online "sphinx>=1.6.0" mkvenv ensure "qemu.qmp==0.0.2" It's designed to look for packages in three places, in order: (1) In system packages, if the version installed is already good enough. This way your distribution-provided meson, sphinx, etc are always used as first preference. (2) In a vendored packages directory. Here I am suggesting qemu.git/python/wheels/ as that directory. This is intended to serve as a replacement for vendoring the meson source for QEMU tarballs. It is also highly likely to be extremely useful for packaging the "qemu.qmp" package in source distributions for platforms that do not yet package qemu.qmp separately. (3) Online, via PyPI, ***only when "--online" is passed***. This is only ever used as a fallback if the first two sources do not have an appropriate package that meets the requirement. The ability to build QEMU and run tests *completely offline* is not impinged.

2023-05-18mkvenv: add nested venv workaroundJohn Snow
Python virtual environments do not typically nest; they may inherit from the top-level system packages or not at all. For our purposes, it would be convenient to emulate "nested" virtual environments to allow callers of the configure script to install specific versions of python utilities in order to test build system features, utility version compatibility, etc. While it is possible to install packages into the system environment (say, by using the --user flag), it's nicer to install test packages into a totally isolated environment instead. As detailed in https://www.qemu.org/2023/03/24/python/, Emulate a nested venv environment by using .pth files installed into the site-packages folder that points to the parent environment when appropriate.

2023-05-18python: add mkvenv.pyJohn Snow
This script will be responsible for building a lightweight Python virtual environment at configure time. It works with Python 3.6 or newer. It has been designed to: - work *offline*, no PyPI required. - work *quickly*, The fast path is only ~65ms on my machine. - work *robustly*, with multiple fallbacks to keep things working. - work *cooperatively*, using system packages where possible. (You can use your distro's meson, no problem.) Due to its unique position in the build chain, it exists outside of the installable python packages in-tree and *must* be runnable without any third party dependencies. Under normal circumstances, the only dependency required to execute this script is Python 3.6+ itself. The script is *faster* by several seconds when setuptools and pip are installed in the host environment, which is probably the case for a typical multi-purpose developer workstation. In the event that pip/setuptools are missing or not usable, additional dependencies may be required on some distributions which remove certain Python stdlib modules to package them separately: - Debian may require python3-venv to provide "ensurepip" - NetBSD may require py310-expat to provide "pyexpat" * (* Or whichever version is current for NetBSD.)

These $TMPDIR's are generated from a user's unix UID and UUID [1], which can create a relatively long path: /var/folders/d7/rz20f6hd709c1ty8f6_6y_z40000gn/T/ QEMU's avocado tests create a temporary directory prefixed by "avo_qemu_sock_", and create QMP sockets within _that_ as well. The QMP socket is unnecessarily long, because a temporary directory is created for every QEMUMachine object. /avo_qemu_sock_uh3w_dgc/qemu-37331-10bacf110-monitor.sock The path limit for unix sockets on macOS is 104: [2] /* * [XSI] Definitions for UNIX IPC domain. */ struct sockaddr_un { unsigned char sun_len; /* sockaddr len including null */ sa_family_t sun_family; /* [XSI] AF_UNIX */ char sun_path[104]; /* [XSI] path name (gag) */ }; This results in avocado tests failing on macOS because the QMP unix socket can't be created, because the path is too long: ERROR| Failed to establish connection: OSError: AF_UNIX path too long This change resolves by reducing the size of the socket directory prefix and the suffix on the QMP and console socket names. The result is paths like this: pdel@pdel-mbp:/var/folders/d7/rz20f6hd709c1ty8f6_6y_z40000gn/T $ tree qemu* qemu_df4evjeq qemu_jbxel3gy qemu_ml9s_gg7 qemu_oc7h7f3u qemu_oqb1yf97 ├── 10a004050.con └── 10a004050.qmp [1] https://apple.stackexchange.com/questions/353832/why-is-mac-osx-temp-directory-in-weird-path [2] /Library/Developer/CommandLineTools/SDKs/MacOSX12.3.sdk/usr/include/sys/un.h Signed-off-by: Peter Delevoryas <peter@pjd.dev> Reviewed-by: Daniel P.

2023-01-24python: QEMUMachine: enable qmp accept timeout by defaultVladimir Sementsov-Ogievskiy
I've spent much time trying to debug hanging pipeline in gitlab. I started from and idea that I have problem in code in my series (which has some timeouts). Finally I found that the problem is that I've used QEMUMachine class directly to avoid qtest, and didn't add necessary arguments. Qemu fails and we wait for qmp accept endlessly. In gitlab it's just stopped by timeout (one hour) with no sign of what's going wrong. With timeout enabled, gitlab don't wait for an hour and prints all needed information.

2023-01-04python/machine: Handle termination cases without QMPJohn Snow
If we request a shutdown of a VM without a QMP console, we'll just hang waiting. Not ideal. Add in code that attempts graceful termination in these cases. Tested lightly; it appears to work and I doubt we rely on this case anywhere, but it's a corner you're allowed to wedge yourself in, so it should be handled.

2023-01-04python/machine: Add debug logging to key state changesJohn Snow
When key decisions are made about the lifetime of the VM process being managed, there's no log entry. Juxtaposed with the very verbose runstate change logging of the QMP module, machine seems a bit too introverted now. Season the machine.py module with logging statements to taste to help make a tastier soup. Signed-off-by: John Snow <jsnow@redhat.com>

typeshed (included in mypy) recently updated to improve the typing for WriteTransport objects. I was working around this, but now there's a version where I shouldn't work around it.

2022-04-21python: rename qemu.aqmp to qemu.qmpJohn Snow
Now that we are fully switched over to the new QMP library, move it back over the old namespace. This is being done primarily so that we may upload this package simply as "qemu.qmp" without introducing confusion over whether or not "aqmp" is a new protocol or not. The trade-off is increased confusion inside the QEMU developer tree. Sorry! Note: the 'private' member "_aqmp" in legacy.py also changes to "_qmp"; not out of necessity, but just to remove any traces of the "aqmp" name.
