For everything typed so far, type this parameter as
Optional[QAPISourceInfo].
In the most generic case, QAPISchemaEntity's info field may be None to
represent types that come from built-in definitions. Although some
Entity types may not currently have any built-in definitions, it is not
easily possible to constrain the type except on an ad-hoc basis using
assertions.
It's easier and simpler, then, to just say it's always an Optional type.

QAPISchemaGenCommandVisitor.visit_command() needs to generate the
marshalling function into the current module, and also generate its
registration into the ./init system module. The latter is done
somewhat awkwardly: .__init__() creates a QAPIGenCCode that will not
be written out, each .visit_command() adds its registration to it, and
.visit_end() copies its contents into the ./init module it creates.
Instead provide the means to temporarily switch to another module.
Create the ./init module in .visit_begin(), and generate its initial
part. Add registrations to it in .visit_command(). Finish it in
.visit_end().

All of the QAPI include statements are changed to be package-aware, as
explicit relative imports.
A quirk of Python packages is that the name of the package exists only
*outside* of the package. This means that to a module inside of the qapi
folder, there is inherently no such thing as the "qapi" package. The
reason these imports work is because the "qapi" package exists in the
context of the caller -- the execution shim, where sys.path includes a
directory that has a 'qapi' folder in it.
When we write "from qapi import sibling", we are NOT referencing the folder
'qapi', but rather "any package named qapi in sys.path". If you should
so happen to have a 'qapi' package in your path, it will use *that*
package.
When we write "from .sibling import foo", we always reference explicitly
our sibling module; guaranteeing consistency in *where* we are importing
these modules from.
This can be useful when working with virtual environments and packages
in development mode. In development mode, a package is installed as a
series of symlinks that forwards to your same source files. The problem
arises because code quality checkers will follow "import qapi.x" to the
"installed" version instead of the sibling file and -- even though they
are the same file -- they have different module paths, and this causes
cyclic import problems, false positive type mismatch errors, and more.
It can also be useful when dealing with hierarchical packages, e.g. if
we allow qemu.core.qmp, qemu.qapi.parser, etc.

Subclasses of QAPISchemaModularCVisitor need to ._add_module() this
special module to enable code generation for built-ins. When this
hasn't been done, QAPISchemaModularCVisitor.visit_module() does
nothing for the special module. That looks like built-ins could

The "oob" idea is proposed by Markus Armbruster in following thread:
https://lists.gnu.org/archive/html/qemu-devel/2017-09/msg02057.html
This new "allow-oob" boolean will be exposed by "query-qmp-schema" as
well for command entries, so that QMP clients can know which commands
can be used in out-of-band calls. For example the command "migrate"
originally looks like:
{"name": "migrate", "ret-type": "17", "meta-type": "command",
"arg-type": "86"}
And it'll be changed into:
{"name": "migrate", "ret-type": "17", "allow-oob": false,
"meta-type": "command", "arg-type": "86"}
This patch only provides the QMP interface level changes. It does not

Our qapi-schema.json is composed of modules connected by include
directives, but the generated code is monolithic all the same: one
qapi-types.h with all the types, one qapi-visit.h with all the
visitors, and so forth. These monolithic headers get included all
over the place. In my "build everything" tree, adding a QAPI type
recompiles about 4800 out of 5100 objects.
We wouldn't write such monolithic headers by hand. It stands to
reason that we shouldn't generate them, either.
Split up generated qapi-types.h to mirror the schema's modular
structure: one header per module. Name the main module's header
qapi-types.h, and sub-module D/B.json's header D/qapi-types-B.h.
Mirror the schema's includes in the headers, so that qapi-types.h gets
you everything exactly as before. If you need less, you can include
one or more of the sub-module headers. To be exploited shortly.
Split up qapi-types.c, qapi-visit.h, qapi-visit.c, qmp-commands.h,
qmp-commands.c, qapi-event.h, qapi-event.c the same way.
qmp-introspect.h, qmp-introspect.c and qapi.texi remain monolithic.
The split of qmp-commands.c duplicates static helper function
qmp_marshal_output_str() in qapi-commands-char.c and
qapi-commands-misc.c. This happens when commands returning the same
type occur in multiple modules. Not worth avoiding.
Since I'm going to rename qapi-event.[ch] to qapi-events.[ch], and
qmp-commands.[ch] to qapi-commands.[ch], name the shards that way
already, to reduce churn. This requires temporary hacks in
commands.py and events.py. Similarly, c_name() must temporarily
be taught to munge '/' in common.py. They'll go away with the rename.
