Debian only introduced tomli in the bookworm release. Use a
vendored wheel to avoid requiring a package that is only in
bullseye-backports and is also absent in Ubuntu 20.04.
While at it, fix an issue in the vendor.py scripts which does
not add a newline after each package and hash.

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.
The plan is to have a TOML file with one entry per package, for example
[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.

Move the matching between the "absent" array and dep_specs[0] inside

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.

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).

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.

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.

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.)

We don't really care which python runs it; it exists as a meta-utility

This is a routine that is designed to print some usable info for human

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

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.

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.

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.)

On macOS, private $TMPDIR's are the default. 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:

Newer flake8 versions are a bit pickier about the config file, and my
in-line comment confuses the parser. Fix it.

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.

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.

We have about 30 instances of the typo/variant spelling 'writeable',
and over 500 of the more common 'writable'. Standardize on the
latter.
Change produced with:
sed -i -e 's/\([Ww][Rr][Ii][Tt]\)[Ee]\([Aa][Bb][Ll][Ee]\)/\1\2/g' $(git grep -il writeable)
and then hand-undoing the instance in linux-headers/linux/kvm.h.
Most of these changes are in comments or documentation; the
exceptions are:
* a local variable in accel/hvf/hvf-accel-ops.c
* a local variable in accel/kvm/kvm-all.c
* the PMCR_WRITABLE_MASK macro in target/arm/internals.h
* the EPT_VIOLATION_GPA_WRITABLE macro in target/i386/hvf/vmcs.h
(which is never used anywhere)
* the AR_TYPE_WRITABLE_MASK macro in target/i386/hvf/vmx.h
(which is never used anywhere)

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.
Unfortunately this creates some minor ugliness if I want to support both
pre- and post-0.950 versions. For now, for my sanity, just disable the
unused-ignores warning.

Pylint upgraded recently (2.13.z) and having a pylint: disable comment
in the middle of an argument field causes it some grief (It appears to
stop parsing when it encounters it, causing some syntax problems). Since
the duplicate line threshold was bumped up in 22305c2a08, we don't
need this workaround anymore. Drop it.
