QAPIDoc uses a state machine to for processing of documentation lines.
Its state is encoded as an enum QAPIDoc._state (well, as enum-like
class actually, thanks to our infatuation with Python 2).
All we ever do with the state is calling the state's function to
process a line of documentation. The enum values effectively serve as
handles for the functions.
Eliminate the rather wordy indirection: store the function to call in
QAPIDoc._append_line. Update and improve comments.

Documentation comments follow a certain structure: First, we have a text
with a general description (called QAPIDoc.body). After this,
descriptions of the arguments follow. Finally, we have a part that
contains various named sections.
The code doesn't show this structure, but just checks various attributes
that indicate indirectly which part is being processed, so it happens to
do the right set of things in the right phase. This is hard to follow,
and adding support for documentation of features would be even harder.
This patch restructures the code so that the three parts are clearly
separated. The code becomes a bit longer, but easier to follow. The
resulting output remains unchanged.

Sometimes, the behaviour of QEMU changes without a change in the QMP
syntax (usually by allowing values or operations that previously
resulted in an error). QMP clients may still need to know whether
they can rely on the changed behavior.
Let's add feature flags to the QAPI schema language, so that we can make
such changes visible with schema introspection.
An example for a schema definition using feature flags looks like this:
{ 'struct': 'TestType',
'data': { 'number': 'int' },
'features': [ 'allow-negative-numbers' ] }
Introspection information then looks like this:
{ "name": "TestType", "meta-type": "object",
"members": [
{ "name": "number", "type": "int" } ],
"features": [ "allow-negative-numbers" ] }
This patch implements feature flags only for struct types. We'll
implement them more widely as needed.

In commit f2a3b549e3 we updated our u-boot blob

Apart from defconfig (which is a no-op),
allyesconfig/allnoconfig/randcondfig can be implemented simply by ignoring
the RHS of assignments and "default" statements. The RHS is replaced
respectively by "true", "false" or a random value.
However, allyesconfig and randconfig do not quite work, because all the
files for hw/ARCH/Kconfig are sourced and therefore you could end up
enabling some ARM boards in x86 or things like that. This is left for
future work, but I am leaving it in to help debugging minikconf itself.

The make_device_config.sh script is replaced by minikconf, which
is modified to support the same command line as its predecessor.
The roots of the parsing are default-configs/*.mak, Kconfig.host and
hw/Kconfig. One difference with make_device_config.sh is that all symbols
have to be defined in a Kconfig file, including those coming from the
configure script. This is the reason for the Kconfig.host file introduced
in the previous patch. Whenever a file in default-configs/*.mak used
$(...) to refer to a config-host.mak symbol, this is replaced by a
Kconfig dependency; this part must be done already in this patch
for bisectability.

There are three parts in the semantic analysis:
1) evaluating expressions. This is done as a simple visit
of the Expr nodes.
2) ordering clauses. This is done by constructing a graph of variables.
There is an edge from X to Y if Y depends on X, if X selects Y, or if
X appears in a conditional selection of Y; in other words, if the value
of X can affect the value of Y. Each clause has a "destination" variable
whose value can be affected by the clause, and clauses will be processed
according to a topological sorting of their destination variables.
Defaults are processed after all other clauses with the same destination.
3) deriving the value of the variables. This is done by processing
the clauses in the topological order provided by the previous step.
A "depends on" clause will force a variable to False, a "select" clause
will force a variable to True, an assignment will force a variable
to its RHS. A default will set a variable to its RHS if it has not
been set before. Because all variables have a default, after visiting
all clauses all variables will have been set.

This implements a scanner and recursive descent parser for Kconfig-like
configuration files. The only "action" of the parser is for now to
detect undefined variables and process include files.
The main differences between Kconfig and this are:
* only the "bool" type is supported
* variables can only be defined once
* choices are not supported (but they could be added as syntactic
sugar for multiple Boolean values)
* menus and other graphical concepts (prompts, help text) are not
supported
* assignments ("CONFIG_FOO=y", "CONFIG_FOO=n") are parsed as part
of the Kconfig language, not as a separate file.
The idea was originally by Ákos Kovács, but I could not find his
implementation so I had to redo it.

We generally put implicitly defined types in whatever module triggered
their definition. This is wrong for array types, as the included test
case demonstrates. Let's have a closer look at it.
Type 'Status' is defined sub-sub-module.json. Array type ['Status']
occurs in main module qapi-schema-test.json and in
include/sub-module.json. The main module's use is first, so the array
type gets put into the main module.
The generated C headers define StatusList in qapi-types.h. But
include/qapi-types-sub-module.h uses it without including
qapi-types.h. Oops.
To fix that, put the array type into its element type's module.
Now StatusList gets generated into qapi-types-sub-module.h, which all
its users include.

The #include directives to pull in sub-modules use file names relative
to the main module. Works only when all modules are in the same
directory, or the main module's output directory is in the compiler's
include path. Use relative file names instead.
The dummy variable we generate to avoid empty .o files has an invalid
name for sub-modules in other directories. Fix that.
Both messed up in commit 252dc3105f "qapi: Generate separate .h, .c
for each module". Escaped testing because tests/qapi-schema-test.json
doesn't cover sub-modules in other directories, only
tests/qapi-schema/include-relpath.json does, and we generate and
compile C code only for the former, not the latter. Fold the latter
into the former. This would have caught the mistakes fixed in this
commit.

This is a simple move of Python code that wraps common QEMU
functionality, and are used by a number of different tests

By treating that code as a real Python module, we can more easily:
* reuse code
* have a proper place for the module's own unittests
* apply a more consistent style

This reverts commit 7bd2634905.
The commit applied the events' conditions to the members of enum
QAPIEvent. Awkward, because it renders QAPIEvent unusable in
target-independent code as soon as we make an event target-dependent.
Reverting this has the following effects:
* ui/vnc.c can remain target independent.
* monitor_qapi_event_conf[] doesn't have to muck around with #ifdef.
* query-events again doesn't reflect conditionals. I'm going to
deprecate it in favor of query-qmp-schema.
Another option would be to split target-dependent parts off enum
QAPIEvent into a target-dependent enum. Doesn't seem worthwhile right
now.

We neglect to call .visit_module() for the special module we use for
built-ins. Harmless, but clean it up anyway. The
tests/qapi-schema/*.out now show the built-in module as 'module None'.
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
accidentally be generated into the wrong module when a subclass
neglects to call ._add_module(). Can't happen, because built-ins are
all visited before any other module. But that's non-obvious. Switch
off code generation explicitly.
Rename QAPISchemaModularCVisitor._begin_module() to
._begin_user_module().
New QAPISchemaModularCVisitor._is_builtin_module(), for clarity.

The cmd() method of the QEMUQtestProtocol class sends a qtest command
to QEMU but doesn't wait for the return message ("OK", "FAIL", "ERR").
Because of this, it can return control to the caller before the
command has actually finished.
In cases like clock_step or clock_set this means that cmd() can return
before all the timers triggered by the clock change have been fired.
This can be fixed by making cmd() wait for the output of the qtest
command.
This fixes iotests 093 and 136, which are flaky since commit
8258292e18 when the machine is under heavy workload.

In checkpatch we attempt to check for and warn about
block comments which start with /* or /** followed by a
non-blank. Unfortunately a bug in the regex meant that
we would incorrectly warn about comments starting with
"/**" with no following text:
git show 9813dc6ac3954d58ba16b3920556f106f97e1c67|./scripts/checkpatch.pl -
WARNING: Block comments use a leading /* on a separate line
#34: FILE: tests/libqtest.h:233:
+/**
The sequence "/\*\*?" was intended to match either "/*" or "/**",
but Perl's semantics for '?' allow it to backtrack and try the
"matches 0 chars" option if the "matches 1 char" choice leads to
a failure of the rest of the regex to match. Switch to "/\*\*?+"
which uses what perlre(1) calls the "possessive" quantifier form:
this means that if it matches the "/**" string it will not later
backtrack to matching just the "/*" prefix.
The other end of the regex is also wrong: it is attempting
to check for "/* or /** followed by something that isn't
just whitespace", but [ \t]*.+[ \t]* will match on pure
whitespace. This is less significant but means that a line
with just a comment-starter followed by trailing whitespace
will generate an incorrect warning about block comment style
as well as the correct error about trailing whitespace which
a different checkpatch test emits.

This commit introduces a way to do simple printf style logging of probe
points using systemtap. In particular it creates another set of tapsets,
one per emulator:
/usr/share/systemtap/tapset/qemu-*-log.stp
These pre-define probe functions which simply call printf() on their
arguments. The printf() format string is taken from the normal
trace-events files, with a little munging to the format specifiers
to cope with systemtap's more restrictive syntax.
With this you can now do
$ stap -e 'probe qemu.system.x86_64.log.qio*{}'

This tool is clever in that it will automatically change the
SYSTEMTAP_TAPSET env variable to point to the directory containing the
right set of probes for the QEMU binary path you give it. This is useful
if you have QEMU installed in /usr but are trying to test and trace a
binary in /home/berrange/usr/qemu-git. In that case you'd do
$ qemu-trace-stap run /home/berrange/usr/qemu-git/bin/qemu-system-x86_64 'qio*'
And it'll make sure /home/berrange/usr/qemu-git/share/systemtap/tapset
is used for the trace session
The 'qemu-trace-stap' script takes a verbose arg so you can understand
what it is running
$ qemu-trace-stap run /home/berrange/usr/qemu-git/bin/qemu-system-x86_64 'qio*'
Using tapset dir '/home/berrange/usr/qemu-git/share/systemtap/tapset' for binary '/home/berrange/usr/qemu-git/bin/qemu-system-x86_64'
Compiling script 'probe qemu.system.x86_64.log.qio* {}'
Running script, <Ctrl>-c to quit
...trace output...
It can enable multiple probes at once
$ qemu-trace-stap run qemu-system-x86_64 'qio*' 'qcrypto*' 'buffer*'
By default it monitors all existing running processes and all future
launched proceses. This can be restricted to a specific PID using the
--pid arg
$ qemu-trace-stap run --pid 2532 qemu-system-x86_64 'qio*'
Finally if you can't remember what probes are valid it can tell you
$ qemu-trace-stap list qemu-system-x86_64
ahci_check_irq
ahci_cmd_done
ahci_dma_prepare_buf
ahci_dma_prepare_buf_fail
ahci_dma_rw_buf

Or list just those matching a prefix pattern

The '%m' format instructs glibc's printf()/syslog() implementation to
insert the contents of strerror(errno). Since this is a glibc extension
it should generally be avoided in QEMU due to need for portability to a
variety of platforms.
Even though vfio is Linux-only code that could otherwise use "%m", it
must still be avoided in trace-events files because several of the
backends do not use the format string and so this error information is
invisible to them.
The errno string value should be given as an explicit trace argument
instead, making it accessible to all backends. This also allows it to
work correctly with future patches that use the format string with
systemtap's simple printf code.

When generating the trace-events-all file, the build system simply
concatenates all the individual trace-events files. If any one of those

the contents of the first line of the next file appended to it, which is
usually a '#' comment.

emit = qmp_event_get_func_emit();
if (!emit) {
return;
}
qmp = qmp_event_build_dict("FOO");
[put event arguments into @qmp...]
emit(QAPI_EVENT_FOO, qmp);
The value of qmp_event_get_func_emit() depends only on the program:
* In qemu-system-FOO, it's always monitor_qapi_event_queue.
* In tests/test-qmp-event, it's always event_test_emit.
* In all other programs, it's always null.
This is exactly the kind of dependence the linker is supposed to
resolve; we don't actually need an indirection.
Note that things would fall apart if we linked more than one QAPI
schema into a single program: each set of qapi_event_send_FOO() uses
its own event enumeration, yet they share a single emit function.
Which takes the event enumeration as an argument. Which one if
there's more than one?
More seriously: how does this work even now? qemu-system-FOO wants
QAPIEvent, and passes a function taking that to
qmp_event_set_func_emit(). test-qmp-event wants test_QAPIEvent, and
passes a function taking that to qmp_event_set_func_emit().
It works by type trickery, of course:
typedef void (*QMPEventFuncEmit)(unsigned event, QDict *dict);
void qmp_event_set_func_emit(QMPEventFuncEmit emit);
QMPEventFuncEmit qmp_event_get_func_emit(void);
We use unsigned instead of the enumeration type. Relies on both
enumerations boiling down to unsigned, which happens to be true for
the compilers we use.
Clean this up as follows:
* Generate qapi_event_send_FOO() that call PREFIX_qapi_event_emit()
instead of the value of qmp_event_set_func_emit().
* Generate a prototype for PREFIX_qapi_event_emit() into
qapi-events.h.
* PREFIX_ is empty for qapi/qapi-schema.json, and test_ for
tests/qapi-schema/qapi-schema-test.json. It's qga_ for
qga/qapi-schema.json, and doc-good- for
tests/qapi-schema/doc-good.json, but those don't define any events.
* Rename monitor_qapi_event_queue() to qapi_event_emit() instead of
passing it to qmp_event_set_func_emit(). This takes care of
qemu-system-FOO.
* Rename event_test_emit() to test_qapi_event_emit() instead of
passing it to qmp_event_set_func_emit(). This takes care of
tests/test-qmp-event.
* Add a qapi_event_emit() that does nothing to stubs/monitor.c. This
takes care of all other programs that link code emitting QMP events.
* Drop qmp_event_set_func_emit(), qmp_event_get_func_emit().

QTAILQ is a doubly linked list, with a pointer-to-pointer to the last
element from the head, and the previous element from each node.
But if you squint enough, QTAILQ becomes a combination of a singly-linked
forwards list, and another singly-linked list which goes backwards and
is circular. This is the idea that lets QTAILQ implement reverse
iteration: only, because the backwards list points inside the node,
accessing the previous element needs to go two steps back and one
forwards.
What this patch does is implement it in these terms, without actually
changing the in-memory layout at all. The coexistence of the two lists
is realized by making QTAILQ_HEAD and QTAILQ_ENTRY unions of the forwards
pointer and a generic QTailQLink node. Thq QTailQLink can walk the list in
both directions; the union is needed so that the forwards pointer can
have the correct type, as a sort of poor man's template. While there
are other ways to get the same layout without a union, this one has
the advantage of simpler operation in the debugger, because the fields
tqh_first and tqe_next still exist as before the patch. Those fields are
also used by scripts/qemugdb/mtree.py, so it's a good idea to preserve them.
The advantage of the new representation is that the two-back-one-forward
dance done by backwards accesses can be done all while operating on
QTailQLinks. No casting to the head struct is needed anymore because,
even though the QTailQLink's forward pointer is a void *, we can use
typeof to recover the correct type. This patch only changes the
implementation, not the interface. The next patch will remove the head
struct name from the backwards visit macros.

gtester is deprecated by upstream glib (see for example the announcement
at https://blog.gtk.org/2018/07/11/news-from-glib-2-58/) and it does
not support tests that call g_test_skip in some glib stable releases.
glib suggests instead using Automake's TAP support, which gtest itself
supports since version 2.38 (QEMU's minimum requirement is 2.40).
We do not support Automake, but we can use Automake's code to beautify
the TAP output. I chose to use the Perl copy rather than the shell/awk
one, with some changes so that it can accept TAP through stdin, in order
to reuse Perl's TAP parsing package. This also avoids duplicating the
parser between tap-driver.pl and tap-merge.pl.

The generated C enumeration types explicitly set the enumeration
constants to 0, 1, 2, ... That's exactly what you get when you don't
supply values.
Drop the explicit values. No change now, but it will avoid gaps in
the values when we later add support for 'if' conditions. Avoiding
such gaps will save us the trouble of changing the ENUM_lookup[]
tables to work without a sentinel.
We'll have to take care to ensure the headers required by the 'if'
conditions get always included before the generated QAPI code.
Fortunately, our convention to include "qemu/osdep.h" first in any .c
ensures that's the case for our CONFIG_FOO macros.

clear distinction between their outputs.

POSIX requires $PWD to be reliable, and we expect all
shells used by qemu scripts to be relatively close to
POSIX. Thus, it is smarter to avoid forking the pwd
executable for something that is already available in
the environment.
So replace it with the following:
sed -i 's/\(`pwd`\|\$(pwd)\)/$PWD/g' $(git grep -l pwd)
Then delete a pointless line assigning PWD to itself.

Python 3.4 introduced the inheritable attribute for FDs. At the same
time, it changed the default so that all FDs are not inheritable by
default, that only inheritable FDs are inherited to subprocesses, and
only if close_fds is explicitly set to False.
Adhere to this by setting close_fds to False when working with
subprocesses that may want to inherit FDs, and by trying to
set_inheritable() on FDs that we do want to bequeath to them.

Since byte strings are no longer the default in Python 3, we have to
explicitly use them where we need to, which is mostly when working with
structures. It also means that we need to open a file in binary mode
when we want to use structures.
On the other hand, we have to accomodate for the fact that some
functions (still) work with byte strings but we want to use unicode
strings (in Python 3 at least, and it does not matter in Python 2).
This includes base64 encoding, but it is most notable when working with
the subprocess module: Either we set universal_newlines to True so that
the default streams are opened in text mode (hence this parameter is
aliased as "text" as of 3.7), or, if that is not possible, we have to
decode the output to a normal string.

qerror.h contains leftovers from the now-defunct QError API.
There's only a handful of string macros left, and no one is supposed
to add anything else. The check-qerror.sh script was used to make sure
that all definitions on the qerror.c and qerror.h files were sorted
alphabetically. The former was removed three years ago, and the latter
is now in a different location, so the script doesn't even work (as
a matter of fact the alphabetical order was broken last time someone
added a macro -also in 2015- and no one seemed to notice).
There's no point in fixing this script so let's just remove it.
The rogue macro is also moved to its correct location.

We consciously chose in commit 1a9a507b to hide QAPI type names
from the introspection output on the wire, but added a command
line option -u to unmask the type name when doing a debug build.
The unmask option still remains useful to some other forms of
automated analysis, so it will not be removed; however, when it
is not in use, the generated .c file can be hard to read. At
the time when we first introduced masking, the generated file
consisted only of a monolithic C string, so there was no clean
way to inject any comments.
Later, in commit 7d0f982b, we switched the generation to output
a QLit object, in part to make it easier for future addition of
conditional compilation. In fact, commit d626b6c1 took advantage
of this by passing a tuple instead of a bare object for encoding
the output of conditionals. By extending that tuple, we can now
interject strategic comments.
For now, type name debug aid comments are only output once per
meta-type, rather than at all uses of the number used to encode
the type within the introspection data. But this is still a lot
more convenient than having to regenerate the file with the
unmask operation temporarily turned on - merely search the
generated file for '"NNN" =' to learn the corresponding source
name and associated definition of type NNN.
The generated qapi-introspect.c changes only with the addition
of comments, such as:
| @@ -14755,6 +15240,7 @@
