When the object is not stateful, this repr method prints what you'd
expect. In cases where there are pending events, the output is augmented
to illustrate that.
The object itself has no idea if it's "active" or not, so it cannot

By passing all of the arguments to the base class and overriding the
__str__ method when we want a different "human readable" message that
isn't just printing the list of arguments, we can ensure that all custom
error classes have a reasonable __repr__ implementation.
In the case of ExecuteError, the pseudo-field that isn't actually
correlated to an input argument can be re-imagined as a read-only
property; this forces consistency in the class and makes the repr output
more obviously correct.

The way editable installs work has changed at some point since Fedora 40
was released. Generally, we should be opting to use pyproject.toml
installs (PEP517/518) - but those are not fully supported until v61 of
setuptools, and CentOS Stream 9 ships v53.
Until that time, we can make use of a transitional feature in
pip/setuptools to use "legacy" editable installs, which is enough to fix
"make check-dev" on modern local workstations for now.
By using the environment variable approach to configure pip, we avoid
any problems for older versions of pip that don't recognize this option,
so it's harmless. The config-settings option first appeared in v23 of
pip. editable_mode was first supported by setuptools in v64.
(I'm not currently precisely aware of when the default behavior of '-e'
switched away from 'compat', but it appears to be a joint effect between
setuptools and pip versions.)

Thanks for your service!
Remove the old qapidoc and the option to enable the transmogrifier,
leaving the "transmogrifier" as the ONLY qapi doc generator. This in
effect also converts the QAPI test to use the new documentation
generator, too.
Update doc-good.txt output to match the new doc generator, which I
should've done exactly when we switched over to the transmogrifier, but,
uhh, oops!
Notes on the new format:
1. per-member IFCOND documentation is missing. Known issue.
2. Freeform documentation without a header is now copied through into
the output. This is a bug fix.

Update the python tests to also check QAPI and the QAPI Sphinx
extensions. The docs/sphinx/qapidoc_legacy.py file is not included in
these checks, as it is destined for removal soon. mypy is also not
called on the QAPI Sphinx extensions, owing to difficulties supporting
Sphinx 3.x - 8.x while maintaining static type checking support. mypy
*is* called on all of the QAPI tools themselves, though.
flake8, isort and mypy use the tool configuration from the existing
python directory (in setup.cfg). pylint continues to use the special
configuration located in scripts/qapi/ - that configuration is more
permissive. If we wish to unify the two configurations, that's a
separate series and a discussion for a later date.
The list of pylint ignores is also updated, owing again to the wide
window of pylint version support: newer versions require pragmas to
occasionally silence the "too many positional arguments" warning, but
older versions do not have such a warning category and will instead yelp
about an unrecognized option. Silence that warning, too.
As a result of this patch, one would be able to run any of the following
tests locally from the qemu.git/python directory and have it cover the
QAPI tooling as well. All of the following options run the python tests,
static analysis tests, and linter checks; but with different
combinations of dependencies and interpreters.
- "make check-minreqs" Run tests specifically under our oldest supported
Python and our oldest supported dependencies. This is the test that
runs on GitLab as "check-python-minreqs". This helps ensure we do not
regress support on older platforms accidentally.
- "make check-tox" Runs the tests under the newest supported
dependencies, but under each supported version of Python in turn. At
time of writing, this is Python 3.8 to 3.13 inclusive. This test helps
catch bleeding-edge problems before they become problems for developer
workstations. This is the GitLab test "check-python-tox" and is an
optionally run, may-fail test due to the unpredictable nature of new
dependencies being released into the ecosystem that may cause
regressions.
- "make check-dev" Runs the tests under the newest supported
dependencies using whatever version of Python the user happens to have
installed. This is a quick convenience check that does not map to any
particular GitLab test.
(Note! check-dev may be busted on Fedora 41 and bleeding edge versions
of setuptools. That's unrelated to this patch and I'll address it
separately and soon. Thank you for your patience, --mgmt)
Finally, finally, finally: this means that QAPI tooling will be linted
and type-checked from the GitLab pipelines.

We pin all dependencies for the "check-minreqs" test because pip lacks a
dependency resolver that installs "the oldest possible package that
meets dependency criteria". So, in order to test our stated minimum
requirements, we pin all of our dependencies (and their dependencies,
transitively) at the oldest possible versions that still work and pass
tests; proving that our minimum requirements are correct.
(It also ensures no new features accidentally sneak in from developers
on newer platforms.)
A few transitive dependencies were omitted from the pinned dependency
file by accident; as a result, pip's dependency solver can pull in newer
dependencies, which we don't want. This patch corrects the previous
oversight and pins the missing dependencies.

Python 3.8 went "end of life" in October 2024 and Fedora 42 dropped
this version already, so the "python" CI job is currently failing.

This was used to bootstrap the venv with a TOML parser, after which

3.11+.
