The upcoming functional tests will require pycotap for providing
TAP output from the python-based tests. Since we want to be able
to run some of the tests offline by default, too, let's install
it along with meson in our venv if necessary (it's size is only
5 kB, so adding the wheel here should not really be a problem).
The wheel file has been obtained with:
pip download --only-binary :all: --dest . --no-cache pycotap

Occasionally some avocado tests will fail waiting for console line
despite the machine running correctly. Console data goes missing, as can
be seen in the console log. This is due to _console_interaction calling
makefile() on the console socket each time it is invoked, which must be
losing old buffer contents when going out of scope.
It is not enough to makefile() with buffered=0. That helps significantly
but data loss is still possible. My guess is that readline() has a line
buffer even when the file is in unbuffered mode, that can eat data.
Fix this by providing a console file that persists for the life of the
console.

Debian 10 is not anymore a supported distro, since Debian 12 was
released on June 10, 2023. Our supported build platforms as of today
all support at least 3.8 (and all of them except for Ubuntu 20.04
support 3.9):
openSUSE Leap 15.5: 3.6.15 (3.11.2)
CentOS Stream 8: 3.6.8 (3.8.13, 3.9.16, 3.11.4)
CentOS Stream 9: 3.9.17 (3.11.4)
Fedora 37: 3.11.4
Fedora 38: 3.11.4
Debian 11: 3.9.2
Debian 12: 3.11.2
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: 3.10.12
NetBSD 9.3: 3.9.13*
FreeBSD 12.4: 3.9.16
FreeBSD 13.1: 3.9.18
OpenBSD 7.2: 3.9.17
Note: NetBSD does not appear to have a default meta-package, but offers
several options, the lowest of which is 3.7.15. However, "python39"
appears to be a pre-requisite to one of the other packages we request
in tests/vm/netbsd.
Since it is safe under our supported platform policy, bump our
minimum supported version of Python to 3.8. The two most interesting
features to have by default include:
- the importlib.metadata module, whose lack is responsible for over 100
lines of code in mkvenv.py
- improvements to asyncio, for example asyncio.CancelledError
inherits from BaseException rather than Exception
In addition, code can now use the assignment operator ':='
Because mypy now learns about importlib.metadata, a small change to
mkvenv.py is needed to pass type checking.

This reverts commit e8e4298fea.
ensuregroup allows to specify both the acceptable versions of avocado,
and a locked version to be used when avocado is not installed as a system
pacakge. This lets us install avocado in pyvenv/ using "mkvenv.py" and
reuse the distro package on Fedora and CentOS Stream (the only distros
where it's available).
ensuregroup's usage of "(>=..., <=...)" constraints when evaluating
the distro package, and "==" constraints when installing it from PyPI,
makes it possible to avoid conflicts between the known-good version and
a package plugins included in the distro.
This is because package plugins have "==" constraints on the version
that is included in the distro, and, using "pip install avocado==88.1"
on a venv that includes system packages will result in an error:
avocado-framework-plugin-varianter-yaml-to-mux 98.0 requires avocado-framework==98.0, but you have avocado-framework 88.1 which is incompatible.
avocado-framework-plugin-result-html 98.0 requires avocado-framework==98.0, but you have avocado-framework 88.1 which is incompatible.
But at the same time, if the venv does not include a system distribution
of avocado then we can install a known-good version and stick to LTS
releases.

Debian only introduced tomli in the bookworm release. Use a

Introduce a new subcommand that retrieves the packages to be installed
from a TOML file. This allows being more flexible in using the system
version of a package, while at the same time using a known-good version
when installing the package. This is important for packages that
sometimes have backwards-incompatible changes or that depend on
specific versions of their dependencies.
Compared to JSON, TOML is more human readable and easier to edit. A
parser is available in 3.11 but also available as a small (12k) package
for older versions, tomli. While tomli is bundled with pip, this is only
true of recent versions of pip. Of all the supported OSes pretty much
only FreeBSD has a recent enough version of pip while staying on Python
<3.11. So we cannot use the same trick that is in place for distlib.

We would like to place all Python dependencies in the same file, so that
we can add more information without having long and complex command lines.

[avocado]
avocado-framework = {
accepted = "(>=88.1, <93.0)",
installed = "88.1",
canary = "avocado"
}
Each TOML section will thus be a dictionary of dictionaries. Modify
mkvenv.py's workhorse function, _do_ensure, to already operate on such
a data structure. The "ensure" subcommand is modified to separate the
depspec into a name and a version part, and use the result (plus the
--diagnose argument) to build a dictionary for each command line argument.

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

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).

importlib.metadata is just as good as distlib.database and a bit more

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

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

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

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.)

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. It's also
possible that this bug might appear on other derivative platforms and
this workaround may prove useful.
