It turns out you can do this directly from Python ... and because of
this, you don't need to worry about setting the inheritability of the
fds or spawning another process.
Doing this is helpful because it allows QEMUMonitorProtocol to keep its
file descriptor and socket object as private implementation
details. /that/ is helpful in turn because it allows me to write a

All callers in the tree *already* clear the events after a call to
get_events(). Do it automatically instead and update callsites to remove
the manual clear call.
These semantics are quite a bit easier to emulate with async QMP, and
nobody appears to be abusing some emergent properties of what happens if
you decide not to clear them, so let's dial down to the dumber, simpler
thing.
Specifically: callers of clear() right after a call to get_events() are
more likely expressing their desire to not see any events they just
retrieved, whereas callers of clear_events() not in relation to a recent
call to pull_event/get_events are likely expressing their desire to
simply drop *all* pending events straight onto the floor. In the sync
world, this is safe enough; in the async world it's nearly impossible to
promise that nothing happens between getting and clearing the
events.
Making the retrieval also clear the queue is vastly simpler.

AQMP is a library, and ideally it should not print error diagnostics
unless a user opts into seeing them. By default, Python will print all
WARNING, ERROR or CRITICAL messages to screen if no logging
configuration has been created by a client application.
In AQMP's case, ERROR logging statements are used to report additional
detail about runtime failures that will also eventually be reported to the
client library via an Exception, so these messages should not be
rendered by default.
(Why bother to have them at all, then? In async contexts, there may be
multiple Exceptions and we are only able to report one of them back to
the client application. It is not reasonably easy to predict ahead of
time if one or more of these Exceptions will be squelched. Therefore,
it's useful to log intermediate failures to help make sense of the
ultimate, resulting failure.)
Add a NullHandler that will suppress these messages until a client
application opts into logging via logging.basicConfig or similar. Note
that upon calling basicConfig(), this handler will *not* suppress these
messages from being displayed by the client's configuration.

Add an implementation for send_fd_scm to the async QMP implementation.
Like socket_scm_helper mentions, a non-empty payload is required for
QEMU to process the ancillary data. A space is most useful because it
does not disturb the parsing of subsequent JSON objects.
A note on "voiding the warranty":
Python 3.11 removes support for calling sendmsg directly from a
transport's socket. There is no other interface for doing this, our use
case is, I suspect, "quite unique".
As far as I can tell, this is safe to do -- send_fd_scm is a synchronous
function and we can be guaranteed that the async coroutines will *not* be
running when it is invoked. In testing, it works correctly.
I investigated quite thoroughly the possibility of creating my own
asyncio Transport (The class that ultimately manages the raw socket
object) so that I could manage the socket myself, but this is so wildly
invasive and unportable I scrapped the idea. It would involve a lot of
copy-pasting of various python utilities and classes just to re-create
the same infrastructure, and for extremely little benefit. Nah.
Just boldly void the warranty instead, while I try to follow up on

This image is intended for building whatever the native versions of
QEMU are for the host architecture. This will hopefully be an aid for
3rd parties who want to be able to build QEMU themselves without
redoing all the dependencies themselves.
We disable the registry because we currently don't have multi-arch
support there.

I was getting prompted by GitHub for new permissions but it turns out
per https://github.com/dessant/repo-lockdown/issues/6:
Repo Lockdown has been rewritten for GitHub Actions, offering new
features and better control over your automation presets. The legacy
GitHub App has been deprecated, and the public instance of the app
has been shut down.
So this is what I've done. As the issues tab is disabled I've removed
the handling for issues from the new version.

Coverity doesn't know enough about how we have arranged our plugin TCG
ops to know we will always have incremented insn_idx before injecting
the callback. Let us assert it for the benefit of Coverity and protect
ourselves from accidentally breaking the assumption and triggering
harder to grok errors deeper in the code if we attempt a negative
indexed array lookup.
However to get to this point we re-factor the code and remove the
second hand instruction boundary detection in favour of scanning the
full set of ops and using the existing INDEX_op_insn_start to cleanly
detect when the instruction has started. As we no longer need the
plugin specific list of ops we delete that.
My initial benchmarks shows no discernible impact of dropping the
plugin specific ops list.

We use INDEX_op_insn_start to make the start of instruction boundaries.
If we don't do it in the .insn_start hook things get confused especially
now plugins want to use that marking to identify the start of instructions
and will bomb out if it sees instrumented ops before the first instruction
boundary.

Some functions of the plugin API were missing in
the symbol list. However, they are all used by
the contributed example plugins. QEMU fails to
load the plugin if the function symbol is not
exported.

A typo meant the substitution would not work, and the placeholder in the
target file didn't even exist.
The result was that tests were never run on the FreeBSD and macOS jobs,
only a basic build.

The check-patch job is intended to be used by contributors or
subsystem maintainers to see if there are style mistakes. The
false positive rate is too high to be used in a gating scenario
so should not run it on the upstream repo ever.

This is a leftover from the days when we were using Travis excessively,
but since x86 jobs are not really usable there anymore, this job has
likely never been used since many months. Let's simply remove it now.
