Out-of-band command execution was introduced in commit cf869d53172.
Unfortunately, we ran into a regression, and had to turn it into an
experimental option for 2.12 (commit be933ffc23).
http://lists.gnu.org/archive/html/qemu-devel/2018-03/msg06231.html
The regression has since been fixed (commit 951702f39c7 "monitor: bind
dispatch bh to iohandler context"). A thorough re-review of OOB
commands led to a few more issues, which have also been addressed.
This patch partly reverts be933ffc23 (monitor: new parameter "x-oob"),
and makes QMP monitors again offer capability "oob" whenever they can
provide it, i.e. when the monitor's character device is capable of
running in an I/O thread.
Some trivial touch-up in the test code is required to make sure qmp-test
won't break.

When the lexer chokes on an input character, it consumes the
character, emits a JSON error token, and enters its start state. This
can lead to suboptimal error recovery. For instance, input
0123 ,
produces the tokens
JSON_ERROR 01
JSON_INTEGER 23
JSON_COMMA ,
Make the lexer skip characters after a lexical error until a
structural character ('[', ']', '{', '}', ':', ','), an ASCII control
character, or '\xFE', or '\xFF'.
Note that we must not skip ASCII control characters, '\xFE', '\xFF',
because those are documented to force the JSON parser into known-good
state, by docs/interop/qmp-spec.txt.
The lexer now produces
JSON_ERROR 01
JSON_COMMA ,
Update qmp-test for the nicer error recovery: QMP now reports just one
error for input %p instead of two. Also drop the newline after %p; it
was needed to tease out the second error.

The JSON parser optionally supports interpolation. The lexer
recognizes interpolation tokens unconditionally. The parser rejects
them when interpolation is disabled, in parse_interpolation().
However, it neglects to set an error then, which can make
json_parser_parse() fail without setting an error.
Move the check for unwanted interpolation from the parser's
parse_interpolation() into the lexer's finite state machine. When
interpolation is disabled, '%' is now handled like any other
unexpected character.
The next commit will improve how such lexical errors are handled.

Bonus: we now recover more nicely from unclosed strings. E.g.

handle_qmp_command() reports certain errors right away. This is wrong
when OOB is enabled, because the errors can "jump the queue" then, as
the previous commit demonstrates.
To fix, we need to delay errors until dispatch. Do that for semantic
errors, mostly by reverting ill-advised parts of commit cf869d53172
"qmp: support out-of-band (oob) execution". Bonus: doesn't run
qmp_dispatch_check_obj() twice, once in handle_qmp_command(), and
again in do_qmp_dispatch(). That's also due to commit cf869d53172.

When OOB is enabled, out-of-band commands are executed right away,
everything else is queued. This lets out-of-band commands "jump the
queue".
However, certain errors are always reported right away, and therefore
can jump the queue even when the erroneous input does not request
out-of-band execution. These errors are pretty unlikely to occur in
production, but it's wrong all the same. Mark FIXME.

Commit cf869d53172 "qmp: support out-of-band (oob) execution" added a
general mechanism for command-independent arguments just for an
out-of-band flag:
The "control" key is introduced to store this extra flag. "control"
field is used to store arguments that are shared by all the commands,
rather than command specific arguments. Let "run-oob" be the first.
However, it failed to reject unknown members of "control". For
instance, in QMP command
{"execute": "query-name", "id": 42, "control": {"crap": true}}
"crap" gets silently ignored.
Instead of fixing this, revert the general "control" mechanism
(because YAGNI), and do it the way I initially proposed, with key
"exec-oob". Simpler code, simpler interface.
An out-of-band command
{"execute": "migrate-pause", "id": 42, "control": {"run-oob": true}}
becomes
{"exec-oob": "migrate-pause", "id": 42}

tests/qmp-test tests an out-of-band command overtaking a slow in-band
command. To do that, it needs:
1. An in-band command that *reliably* takes long enough to be
overtaken.
2. An out-of-band command to do the overtaking.
3. To avoid delays, a way to make the in-band command complete quickly
after it was overtaken.
To satisfy these needs, commit 469638f9cb3 provides the rather
peculiar oob-capable QMP command x-oob-test:
* With "lock": true, it waits for a global semaphore.
* With "lock": false, it signals the global semaphore.
To satisfy 1., the test runs x-oob-test in-band with "lock": true.
To satisfy 2. and 3., it runs x-oob-test out-of-band with "lock": false.
Note that waiting for a semaphore violates the rules for oob-capable
commands. Running x-oob-test with "lock": true hangs the monitor
until you run x-oob-test with "lock": false on another monitor (which
you might not have set up).
Having an externally visible QMP command that may hang the monitor is
not nice. Let's apply a little more ingenuity to the problem. Idea:
have an existing command block on reading a FIFO special file, unblock
it by opening the FIFO for writing.
For 1., use
{"execute": "blockdev-add", "id": ID1,
"arguments": {
"driver": "blkdebug", "node-name": ID1, "config": FIFO,
"image": { "driver": "null-co"}}}
where ID1 is an arbitrary string, and FIFO is the name of the FIFO.
For 2., use
{"execute": "migrate-pause", "id": ID2, "control": {"run-oob": true}}
where ID2 is a different arbitrary string. Since there's no migration
to pause, the command will fail, but that's fine; instant failure is
still a test of out-of-band responses overtaking in-band commands.
For 3., open FIFO for writing.
Drop QMP command x-oob-test.

Now that we can safely call QOBJECT() on QObject * as well as its
subtypes, we can have macros qobject_ref() / qobject_unref() that work
everywhere instead of having to use QINCREF() / QDECREF() for QObject
and qobject_incref() / qobject_decref() for its subtypes.
The replacement is mechanical, except I broke a long line, and added a
cast in monitor_qmp_cleanup_req_queue_locked(). Unlike
qobject_decref(), qobject_unref() doesn't accept void *.
Note that the new macros evaluate their argument exactly once, thus no
need to shout them.

Enabling OOB caused several iotests failures; due to the imminent

other patches fix the issues that iotests exposed, it may be turned
back on in time for the release, otherwise it will be 2.13 material;
either way, the framework changes not reverted now do not hurt if
they remain as part of the 2.12 release.
Additionally, revert the tests in the patch 02130314d8 ("qmp: introduce

to keep 'make check' passing.

There were no QMP capabilities defined. Define the first capability,
"oob", to allow out-of-band messages.
After this patch, we will allow QMP clients to enable QMP capabilities
when sending the first "qmp_capabilities" command. Originally we are
starting QMP session with no arguments like:
{ "execute": "qmp_capabilities" }
Now we can enable some QMP capabilities using (take OOB as example,
which is the only capability that we support):
{ "execute": "qmp_capabilities",
"arguments": { "enable": [ "oob" ] } }
When the "arguments" key is not provided, no capability is enabled.
For capability "oob", the monitor needs to be run on a dedicated IO
thread, otherwise the command will fail. For example, trying to enable
OOB on a MUXed typed QMP monitor will fail.
One thing to mention is that QMP capabilities are per-monitor, and also
when the connection is closed due to some reason, the capabilities will
be reset.
Also, touch up qmp-test.c to test the new bits.

The previous commit improved compile time by including less of the
generated QAPI headers. This is impossible for stuff defined directly
in qapi-schema.json, because that ends up in headers that that pull in
everything.
Move everything but include directives from qapi-schema.json to new
sub-module qapi/misc.json, then include just the "misc" shard where
possible.
It's possible everywhere, except:
* monitor.c needs qmp-command.h to get qmp_init_marshal()
* monitor.c, ui/vnc.c and the generated qapi-event-FOO.c need
qapi-event.h to get enum QAPIEvent
Perhaps we'll get rid of those some other day.
Adding a type to qapi/migration.json now recompiles some 120 instead
of 2300 out of 5100 objects.

As a general rule, we prefer avoiding implicit global state
because it makes code harder to safely copy and paste without
thinking about the global state. Although qmp-test does not
maintain parallel qtest connections, it was the last test
assigning to global_qtest. It's just as easy to be explicit
about the state; once all tests have been cleaned up, a later
patch can then get rid of global_qtest and a layer of wrappers
in libqtest.

This cleanup makes the number of objects depending on qapi/qmp/qdict.h
drop from 4550 (out of 4743) to 368 in my "build everything" tree.
For qapi/qmp/qobject.h, the number drops from 4552 to 390.
While there, separate #include from file comment with a blank line.

Currently, a FOO_lookup is an array of strings terminated by a NULL
sentinel.
A future patch will generate enums with "holes". NULL-termination
will cease to work then.
To prepare for that, store the length in the FOO_lookup by wrapping it
in a struct and adding a member for the length.
The sentinel will be dropped next.

The lookup tables have a sentinel, no need to make callers pass their

A command is a query if it has no side effect and yields a result.
Such commands are typically named query-FOO, but there are exceptions.
The basic idea is to find candidates with query-qmp-schema, filter out
the ones that aren't queries with an explicit blacklist, and test the
remaining ones against a QEMU with no special arguments.
The current blacklist is just add-fd.
The test can't do queries with arguments, because it knows nothing
about the arguments. No coverage for query-cpu-model-baseline,
query-cpu-model-comparison, query-cpu-model-expansion, query-rocker,
query-rocker-ports, query-rocker-of-dpa-flows, and
query-rocker-of-dpa-groups.
Most tested commands are expected to succeed. The test does not check
the return value then.
query-balloon and query-vm-generation-id are expected to fail because
they need a virtio-balloon / vmgenid device to succeed, and this test
is too dumb to set one up. Could be addressed later.
query-acpi-ospm-status and query-hotpluggable-cpus are expected to
fail because they require features provided only by special machine
types, and this test is too dumb to set that up. Could also be
addressed later.
Several commands may either be functional or stubs that always fail,
depending on build configuration. Ideally, the stubs shouldn't be in
query-qmp-schema, but that requires QAPI schema compile-time
configuration, which we don't have, yet. Until we do, we need to
figure out whether a command is a stub. When we have a suitable
CONFIG_FOO preprocessor symbol is available, use that. Else,
simply blacklist the command for now.
We get basic test coverage for the following commands, except as
noted:
qom-list-types
query-acpi-ospm-status (expected to fail)
query-balloon (expected to fail)
query-block
query-block-jobs
query-blockstats
query-chardev
query-chardev-backends

query-machines
query-memdev

The split between tests/test-qobject-input-visitor.c and
tests/test-qobject-input-strict.c now makes less sense than ever. The
next commit will take care of that.
