The generated qapi_event_send_FOO() take an Error ** argument. They
can't actually fail, because all they do with the argument is passing it
to functions that can't fail: the QObject output visitor, and the
@qmp_emit callback, which is either monitor_qapi_event_queue() or
event_test_emit().
Drop the argument, and pass &error_abort to the QObject output visitor
and @qmp_emit instead.

According to commit 047f7038f5, option --preconfig
[...] allows pausing QEMU in the new RUN_STATE_PRECONFIG state,
allowing the configuration of QEMU from QMP before the machine
jumps into board initialization code of machine_run_board_init()
The intent is to allow management to query machine state and
additionally configure it using previous query results within one
QEMU instance (i.e. eliminate the need to start QEMU twice, 1st to
query board specific parameters and 2nd for actual VM start using
query results for additional parameters).
The implementation is a bit of a hack: it splices in an additional
main loop before machine creation, in special runstate preconfig. New
command exit-preconfig exits that main loop. QEMU continues
initializing, creates the machine, and runs the good old main loop.
The replacement of the main loop is transparent to monitors.
Sadly, some commands expect initialization to be complete. Running
them in --preconfig's main loop violates their preconditions. Since
we don't really know which commands are safe, we use a whitelist.
This drags the concept of run state into the QMP core.
The whitelist is done as a command flag in the QAPI schema (commit
d6fe3d02e9). Drags the concept of run state further into the QAPI
language.
The command flag is exposed in query-qmp-schema (also commit
d6fe3d02e9). This makes it ABI.
I consider the whole thing an offensively ugly hack, but sometimes an
ugly hack is the best we can do to solve a problem people have.
The need described by the commit message quote above is genuine. The
proper solution would be a main loop that permits complete
configuration via QMP. This is out of reach, thus the hack.
However, even though the need is genuine, it isn't urgent: libvirt is
not going to use this anytime soon. Baking a hack into ABI before it
has any users is a bad idea.
This commit reverts the parts of commit d6fe3d02e9 that affect ABI
via query-qmp-schema. The commit did the following:
(1) Add command flag 'allow-preconfig' to the QAPI schema language
(2) Pass it to code generators
(3) Have the commands.py code generator pass it to the command
registry (so commit 047f7038f5 can use it as whitelist)
(4) Add 'allow-preconfig' to SchemaInfoCommand (neglecting to update
qapi-code-gen.txt section "Client JSON Protocol introspection")
(5) Set 'allow-preconfig': true for commands qmp_capabilities,
query-commands, query-command-line-options, query-status
Revert exactly (4), plus a bit of documentation added to
qemu-tech.info in commit 047f7038f5.
Shrinks query-qmp-schema's output from 126.5KiB to 121.8KiB for me.

[Straightforward conflict with commit d626b6c1ae resolved]
The mechanism to find possible type tokens can sometimes be confused and go into an
infinite loop. This happens for example in QEMU for a line that looks like
uint## BITS ##_t S = _S, T = _T; \
uint## BITS ##_t as, at, xs, xt, xd; \
Because the token pasting operator does not have a space before _t, it does not
match $notPermitted. However, (?x) is turned on in the regular expression for
modifiers, and thus ##_t matches the empty string. As a result, annotate_values
goes in an infinite loop.
The solution is simply to remove token pasting operators from the string before
looking for modifiers. In the example above, the string uintBITS_t will be
evaluated as a candidate modifier. This is not optimal, but it works as long
as people do not write things like a##s##m, and it fits nicely into sub
possible.
For a similar reason, \# should be rejected always, even if it is not
at end of line or followed by whitespace.
The same patch was sent to the Linux kernel mailing list.

Built-in objects remain unconditional. Explicitly defined objects use

inherit their condition from their users. For most of them, there is
exactly one user, so the condition to use is obvious. The exception
is wrapped types generated for simple union variants, which can be
shared by any number of simple unions. The tight condition would be
the disjunction of the conditions of these simple unions. For now,
use the wrapped type's condition instead. Much simpler and good

Only one existing trace event uses a floating point type. Unfortunately
float and double cannot be supported since SystemTap does not have
floating point types.
Remove float and double from the whitelist and document this limitation.
Update the migrate_transferred trace event to use uint64_t instead of
double.

Python 2 happily reads UTF-8 files in text mode, but Python 3 requires
either UTF-8 locale or an explicit encoding passed to open(). Commit
d4e5ec877c fixed this by setting the en_US.UTF-8 locale. Falls apart
when the locale isn't be available.
Matthias Maier and Arfrever Frehtes Taifersar Arahesis proposed to use
binary mode instead, with manual conversion from bytes to str. Works,
but opening with an explicit encoding is simpler, so do that.
Since Python 2's open() doesn't support the encoding parameter, we
need to suppress it with a version check.

It often happens that just a few discriminator values imply extra data in
a flat union. Existing checks did not make possible to leave other values
uncovered. Such cases had to be worked around by either stating a dummy
(empty) type or introducing another (subset) discriminator enumeration.
Both options create redundant entities in qapi files for little profit.
With this patch it is not necessary anymore to add designated union
fields for every possible value of a discriminator enumeration.

The set_console() method is intended to ease higher level use cases
that require a console device.
The amount of intelligence is limited on purpose, requiring either the
device type explicitly, or the existence of a machine (pattern)
definition.
Because of the console device type selection criteria (by machine
type), users should also be able to define that. It'll then be used
for both '-machine' and for the console device type selection.
Users of the set_console() method will certainly be interested in
accessing the console device, and for that a console_socket property
has been added.

For compatibility reasons, commands that don't use new flag

preconfig state but allowed in all other states like they used
to be.
Within this patch allow following commands in preconfig state:

Rework the update script slightly, add the unistd.h header and its
dependencies on all architectures.
This also removes the IA64 and MIPS from a KVM blacklist:
Linux dropped IA64, and there was never a reason to
exclude MIPS from kvm specifically - it was
excluded due to dependency of its unistd.h on sgidefs.h,
which we also import.

All the xen stable APIs define handle types of the form:
xen<subject of API>_handle
and some define additional handle types of the form:
xen<subject of API>_<purpose of handle>_handle
Examples of these are xenforeignmemory_handle and
xenforeignmemory_resource_handle.
Both of these types will be misparsed by checkpatch if they appear as the
first token in a line since, as types defined by an external library, they
do not conform to the QEMU CODING_STYLE, which suggests CamelCase.
A previous patch (5ac067a24a) added xendevicemodel_handle to the list
of types. This patch changes that to xen\w+_handle such that it will
match all Xen stable API handles of the forms detailed above.

We'll soon need an enumeration type that lists all the softmmu targets
that QEMU (the project) supports. Introduce @SysEmuTarget to
"common.json".
The enum constant @x86_64 doesn't match the QAPI convention of preferring
hyphen ("-") over underscore ("_"). This is intentional; the @SysEmuTarget
constants are supposed to produce QEMU executable names when stringified
and appended to the "qemu-system-" prefix. Put differently, the
replacement text of the TARGET_NAME preprocessor macro must be possible to
look up in the list of (stringified) enum constants.
Like other enum types, @SysEmuTarget too can be used for discriminator
fields in unions. For the @i386 constant, a C-language union member called
"i386" would be generated. On mingw build hosts, "i386" is a macro
however. Add "i386" to "polluted_words" at once.

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.

This avoids checkpatch misparsing (as statements) long function
definitions or declarations, which sometimes start with constructs
like this:
static inline int xendevicemodel_relocate_memory(
xendevicemodel_handle *dmod, domid_t domid, ...
The type xendevicemodel_handle does not conform to Qemu CODING_STYLE,
which would suggest CamelCase. However, it is a type defined by the
Xen Project in xen.git. It would be possible to introduce a typedef
to allow the qemu code to refer to it by a differently-spelled name,
but that would obfuscate more than it would clarify.

Here "oob" stands for "Out-Of-Band". When "allow-oob" is set, it means
the command allows out-of-band execution.
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
contain the real out-of-band execution implementation yet.

The timestamp argument to a trace event method is documented as follows:
The method can also take a timestamp argument before the trace event
arguments:
def runstate_set(self, timestamp, new_state):
...
Timestamps have the uint64_t type and are in nanoseconds.
In reality methods with a timestamp argument actually receive a tuple
like (123456789,) as the timestamp argument. This is due to a bug in
simpletrace.py.
This patch unpacks the tuple so that methods receive the correct
timestamp argument type.

A persistent build problem we see is where a source file
accidentally omits the #include of log.h. This slips through
local developer testing because if you configure with the
default (log) trace backend trace.h will pull in log.h for you.
Compilation fails only if some other backend is selected.
To make this error cause a compile failure regardless of
the configured trace backend, split out the parts of log.h
that trace.h requires into a new log-for-trace.h header.
Since almost all manual uses of the log.h functions will
use constants or functions which aren't in log-for-trace.h,
this will let us catch missing #include "qemu/log.h" more
consistently.

Adding check for `while` and `for` statements, which condition has more than
one line.
The former checkpatch.pl can check `if` statement, which condition has more
than one line, whether block misses brace round, like this:
'''
if (cond1 ||
cond2)
statement;
'''
But it doesn't do the same check for `for` and `while` statements.
Using `(?:...)` instead of `(...)` in regex pattern catch.
Because `(?:...)` is faster and avoids unwanted side-effect.

Move qapi-schema.json to qapi/, so it's next to its modules, and all

qmp-commands.[ch] become qapi-commands.[ch], qapi-event.[ch] become
qapi-events.[ch], and qmp-introspect.[ch] become qapi-introspect.[ch].

[eblake: rebase to master]
Signed-off-by: Eric Blake <eblake@redhat.com>
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.

Linking code from multiple separate QAPI schemata into the same
program is possible, but involves some weirdness around built-in
types:
* We generate code for built-in types into .c only with option
--builtins. The user is responsible for generating code for exactly
one QAPI schema per program with --builtins.
* We generate code for built-in types into .h regardless of
--builtins, but guarded by #ifndef QAPI_VISIT_BUILTIN. Because all
copies of this code are exactly the same, including any combination
of these headers works.
Replace this contraption by something more conventional: generate code
for built-in types into their very own files: qapi-builtin-types.c,
qapi-builtin-visit.c, qapi-builtin-types.h, qapi-builtin-visit.h, but
only with --builtins. Obey --output-dir, but ignore --prefix for
them.
Make qapi-types.h include qapi-builtin-types.h. With multiple
schemata you now have multiple qapi-types.[ch], but only one
qapi-builtin-types.[ch]. Same for qapi-visit.[ch] and
qapi-builtin-visit.[ch].
Bonus: if all you need is built-in stuff, you can include a much
smaller header. To be exploited shortly.

The include directive permits modular QAPI schemata, but the generated
code is monolithic all the same. To permit generating modular code,
the front end needs to pass more information on inclusions to the back
ends. The commit before last added the necessary information to the
parse tree. This commit adds it to the intermediate representation
and its QAPISchemaVisitor. A later commit will use this to to
generate modular code.
New entity QAPISchemaInclude represents inclusions. Call new visitor
method visit_include() for it, so visitors can see the sub-modules a
module includes.
Note that unlike other entities, QAPISchemaInclude has no name, and is
therefore not added to entity_dict.
New QAPISchemaEntity attribute @module names the entity's source file.
Call new visitor method visit_module() when it changes during a visit,
so visitors can keep track of the module being visited.

Improve qapi-gen.py to touch its output files only if they actually
change. Rebuild time for a QAPI doc fix drops from many minutes to a
few seconds. Rebuilds get faster for certain code changes, too. For
instance, adding a simple QMP event now recompiles less than 200

For the qemu log file, we currently just open the path, which will
create the file if it does not exist or overwrite the file if it does
exist.
For the monitor socket, if it already exists, we are currently removing
it, even if it's not created by us.
This patch moves to _pre_launch() the responsibility to create a
temporary directory to host the files so we can remove the whole
directory on _post_shutdown().

Some early python 3.x versions will have different default

to python 2.x and later 3.x versions. Explicitly sort the items
to get a stable ordering.

The iteritems()/itervalues() methods are gone in py3, but the
items()/values() methods are still around. The latter are less
efficient than the former in py2, but this has unmeasurably
small impact on QEMU build time, so taking portability over
efficiency is a net win.

Python 3 no longer supports the bare "print" statement, it must be
called as a normal function with round brackets. It is possible to
opt-in to this new syntax with Python 2.6 onwards by importing the
"print_function" from the "__future__" module, making it easy to
support Python 2 and 3 in parallel.

Python GDB support may use Python 2 or 3.
Inferior.read_memory() may return a 'buffer' with Python 2 or a
'memoryview' with Python 3 (see also
https://sourceware.org/gdb/onlinedocs/gdb/Inferiors-In-Python.html)
The elf.add_vmcoreinfo_note() method expects a "bytes" object. Wrap
the returned memory with bytes(), which works with both 'memoryview'
and 'buffer'.
Fixes a regression introduced with commit
d23bfa91b7 ("add vmcoreinfo").

Use of a loop construct for code that is not intended to repeat
does not make much idiomatic sense, except in one place: it is a
common usage in macros in order to wrap arbitrary code with
single-statement semantics. But when used in a macro, it is more
typical for the caller to supply the trailing ';' when calling
the macro.
Although qemu coding style frowns on bare:
if (cond)
statement1;
else
statement2;
where extra semicolons actually cause syntax errors, we still
want our macro styles to be easily copied to other projects.
Thus, declare it an error if we encounter any form of 'while (0)'
with a semicolon in the same line.
