if $membarrier is empty. For meson, the default can simply be disabled;
if one day we will toggle the default, no change is needed in meson.build.

Now we have no TCG trace events and no longer handle them in the code
we can remove the handling from the tracetool to generate them. vcpu
tracing is still available although the existing syscall event is an
exercise in redundancy (plugins and -strace can also get the
information).

For a long time, we assumed that libxml2 is necessary for parallels
block format support (block/parallels*). However, this format actually
does not use libxml [*]. Since this is the only user of libxml2 in
whole QEMU tree, we can drop all libxml2 checks and dependencies too.
It is even more: --enable-parallels configure option was the only
option which was silently ignored when it's (fake) dependency
(libxml2) isn't installed.
Drop all mentions of libxml2.
[*] Actually the basis for libxml use were introduced in commit
ed279a06c5 ("configure: add dependency") but the implementation
was never merged:

"meson test" can be asked to run tests verbosely; this makes it usable
also for qemu-iotests's own harness, and it lets "make check-block"
reuse mtest2make.py's infrastructure to find and build test dependencies.
Adjust check-block.sh to use the standard exit code that reports a test
as skipped. Alternatively, in the future we could make it produce TAP
output, which is consistent with all other "make check" tests.

We don't generate trace events for tests/ and qga/ because that it is
not simple and not necessary. We have corresponding comments in both
tests/meson.build and qga/meson.build.
Still to not miss possible future qapi code generation call, and not to
forget to enable trace events generation, let's enable it by default.
So, turn option --gen-trace into opposite --no-trace-events and use new
option only in tests/ and qga/ where we already have good comments why
we don't generate trace events code.
Note that this commit enables trace-events generation for qapi-gen.py
call from tests/qapi-schema/meson.build and storage-daemon/meson.build.
Still, both are kind of noop: tests/qapi-schema/ doesn't seem to
generate any QMP command code and no .trace-events files anyway,
storage-daemon/ uses common QMP command implementations and just
generate empty .trace-events

We are going to generate trace events for QMP commands. We should
generate both trace_*() function calls and trace-events files listing
events for trace generator.
So, add an output module FOO.trace-events for each FOO schema module.
Since we're going to add trace events only to command marshallers,
make the trace-events output optional, so we don't generate so many
useless empty files.
Currently nobody set add_trace_events to True, so new functionality is
disabled. It will be enabled for QAPISchemaGenCommandVisitor

First, this permission never protected a node from being changed, as
generic child-replacing functions don't check it.
Second, it's a strange thing: it presents a permission of parent node
to change its child. But generally, children are replaced by different
mechanisms, like jobs or qmp commands, not by nodes.
Graph-mod permission is hard to understand. All other permissions
describe operations which done by parent node on its child: read,
write, resize. Graph modification operations are something completely
different.
The only place where BLK_PERM_GRAPH_MOD is used as "perm" (not shared
perm) is mirror_start_job, for s->target. Still modern code should use
bdrv_freeze_backing_chain() to protect from graph modification, if we
don't do it somewhere it may be considered as a bug. So, it's a bit
risky to drop GRAPH_MOD, and analyzing of possible loss of protection
is hard. But one day we should do it, let's do it now.
One more bit of information is that locking the corresponding byte in
file-posix doesn't make sense at all.

The handling for the XFS_IOC_DIOINFO ioctl is currently quite excessive:
This is not a "real" feature like the other features that we provide with
the "--enable-xxx" and "--disable-xxx" switches for the configure script,
since this does not influence lots of code (it's only about one call to
xfsctl() in file-posix.c), so people don't gain much with the ability to
disable this with "--disable-xfsctl".
It's also unfortunate that the ioctl will be disabled on Linux in case
the user did not install the right xfsprogs-devel package before running
configure. Thus let's simplify this by providing the ioctl definition
on our own, so we can completely get rid of the header dependency and
thus the related code in the configure script.

"meson test" starting with version 0.57 is just as capable and easy to
use as QEMU's own TAP driver. All existing options for "make check"
work. The only required code change involves how to mark "slow" tests;
they need to belong to an additional "slow" suite.
The rules for .tap output are replaced by JUnit XML; GitLab is able
to parse that output and present it in the CI pipeline report.

The "dbus" display backend exports the QEMU consoles and other
UI-related interfaces over D-Bus.
By default, the connection is established on the session bus, but you
can specify a different bus with the "addr" option.
The backend takes the "org.qemu" service name, while still allowing
further instances to queue on the same name (so you can lookup all the
available instances too). It accepts any number of clients at this
point, although this is expected to evolve with options to restrict
clients, or only accept p2p via fd passing.
The interface is intentionally very close to the internal QEMU API,
and can be introspected or interacted with busctl/dfeet etc:
$ ./qemu-system-x86_64 -name MyVM -display dbus
$ busctl --user introspect org.qemu /org/qemu/Display1/Console_0

Despite all the previous fixes, it's still possible for
device-crash-test to wedge itself in the case that QEMU terminates *so
quickly* that it doesn't even begin a connection attempt to our QMP
client. Python will just joyfully wait ad infinitum for a connection
that will now never arrive.
The real fix is to use asyncio to simultaneously poll both the health of
the launched process AND the connection attempt. That's quite a bit more
invasive than just setting a connection timeout, though.
Do the very simplest thing for now.

There is already an entry for this kind of messages earlier in the

the other errors that occur due to a race between QMP connection

We don't need to handle KeyboardInterruptError specifically; we can
instead tighten the scope of the broad Exception handlers to only catch

BaseExceptions, so this does the same thing with less code.

This introduces three different parts of a job designed to run
on a custom runner managed by Red Hat. The goals include:
a) propose a model for other organizations that want to onboard
their own runners, with their specific platforms, build
configuration and tests.
b) bring awareness to the differences between upstream QEMU and the
version available under CentOS Stream, which is "A preview of
upcoming Red Hat Enterprise Linux minor and major releases".
c) because of b), it should be easier to identify and reduce the gap
between Red Hat's downstream and upstream QEMU.
The components of this custom job are:
I) OS build environment setup code:
- additions to the existing "build-environment.yml" playbook
that can be used to set up CentOS/EL 8 systems.
- a CentOS Stream 8 specific "build-environment.yml" playbook
that adds to the generic one.
II) QEMU build configuration: a script that will produce binaries with
features as similar as possible to the ones built and packaged on
CentOS stream 8.
III) Scripts that define the minimum amount of testing that the
binaries built with the given configuration (point II) under the
given OS build environment (point I) should be subjected to.
IV) Job definition: GitLab CI jobs that will dispatch the build/test
jobs (see points #II and #III) to the machine specifically
configured according to #I.

Under SELinux, Unix domain sockets have two labels. One is on the
disk and can be set with commands such as chcon(1). There is a
different label stored in memory (called the process label). This can
only be set by the process creating the socket. When using SELinux +
SVirt and wanting qemu to be able to connect to a qemu-nbd instance,
you must set both labels correctly first.
For qemu-nbd the options to set the second label are awkward. You can
create the socket in a wrapper program and then exec into qemu-nbd.
Or you could try something with LD_PRELOAD.
This commit adds the ability to set the label straightforwardly on the
command line, via the new --selinux-label flag. (The name of the flag
is the same as the equivalent nbdkit option.)
A worked example showing how to use the new option can be found in

This gains some bugfixes, especially:
- it fixes the introspection of array options. While technically we
still support Meson 0.58.2, this issue only appears when adding a new
option and not if the user is just building QEMU. In the relatively
rare case of a contributor using --meson to point to a 0.58 version,
review can catch spurious changes to scripts/meson-buildoptions.sh
easily.
- it fixes "meson test" when it is not the process group leader. Make is
the process group leader when "make check" invokes "meson test", so this
is a requirement for using it as a test harness.

New option parameters unstable-input and unstable-output set policy

deprecated-output set policy for deprecated interfaces (see commit
6dd75472d5 "qemu-options: New -compat to set policy for deprecated
interfaces"). This is intended for testing users of the management
interfaces. It is experimental.
For now, this covers only syntactic aspects of QMP, i.e. stuff tagged
with feature 'unstable'. We may want to extend it to cover semantic
aspects, or the command line.
Note that there is no good way for management application to detect
presence of these new option parameters: they are not visible output
of query-qmp-schema or query-command-line-options. Tolerable, because
it's meant for testing. If running with -compat fails, skip the test.

The next commit will add feature flags to enum members. There's a
problem, though: query-qmp-schema shows an enum type's members as an
array of member names (SchemaInfoEnum member @values). If it showed
an array of objects with a name member, we could simply add more
members to these objects. Since it's just strings, we can't.
I can see three ways to correct this design mistake:
1. Do it the way we should have done it, plus compatibility goo.
We want a ['SchemaInfoEnumMember'] member in SchemaInfoEnum. Since
changing @values would be a compatibility break, add a new member
@members instead.
@values is now redundant. In my testing, output of
qemu-system-x86_64's query-qmp-schema grows by 11% (18.5KiB).
We can deprecate @values now and drop it later. This will break
outmoded clients. Well-behaved clients such as libvirt are
expected to break cleanly.
2. Like 1, but omit "boring" elements of @member, and empty @member.
@values does not become redundant. @members augments it. Somewhat
cumbersome, but output of query-qmp-schema grows only as we make
enum members non-boring.
There is nothing to deprecate here.
3. Versioned query-qmp-schema.
query-qmp-schema provides either @values or @members. The QMP
client can select which version it wants. There is no redundant
output.
We can deprecate old versions and eventually drop them. This will
break outmoded clients. Breaking cleanly is easier than for 1.
While 1 and 2 operate within the common rules for compatible
evolution apply (section "Compatibility considerations" in
docs/devel/qapi-code-gen.rst), 3 bypasses them. Attractive when
operating within the rules is just too awkward. Not the case here.
This commit implements 1. Libvirt developers prefer it.
Deprecate @values in favour of @members. Since query-qmp-schema
compatibility is pretty fundamental for management applications, an
extended grace period is advised.

Right now meson_options.txt lists about 90 options. Each option
needs code in configure to parse it and pass the option down to Meson as
a -D command-line argument; in addition the default must be duplicated
between configure and meson_options.txt. This series tries to remove
the code duplication by generating the case statement for those --enable
and --disable options, as well as the corresponding help text.
About 80% of the options can be handled completely by the new mechanism.
Eight meson options are not of the --enable/--disable kind. Six more need
to be parsed in configure for various reasons documented in the patch,
but they still have their help automatically generated.
The advantages are:
- less code in configure
- parsing and help is more consistent (for example --enable-blobs was
not supported)
- options are described entirely in one place, meson_options.txt.
This make it more attractive to use Meson options instead of
hand-crafted configure options and config-host.mak
A few options change name: --enable-tcmalloc and --enable-jemalloc
become --enable-malloc={tcmalloc,jemalloc}; --disable-blobs becomes
--disable-install-blobs; --enable-trace-backend becomes
--enable-trace-backends. However, the old names are allowed
for backwards compatibility.

Adding static types causes a cycle in the QAPI generator:
[schema -> expr -> parser -> schema]. It exists because the QAPIDoc
class needs the names of types defined by the schema module, but the
schema module needs to import both expr.py/parser.py to do its actual
parsing.
Ultimately, the layering violation is that parser.py should not have any
knowledge of specifics of the Schema. QAPIDoc performs double-duty here
both as a parser *and* as a finalized object that is part of the schema.
In this patch, add the offending type hints alongside the workaround to
avoid the cycle becoming a problem at runtime. See
https://mypy.readthedocs.io/en/latest/runtime_troubles.html#import-cycles
for more information on this workaround technique.
I see three ultimate resolutions here:
(1) Just keep this patch and use the TYPE_CHECKING trick to eliminate
the cycle which is only present during static analysis.
(2) Don't bother to annotate connect_member() et al, give them 'object'
or 'Any'. I don't particularly like this, because it diminishes the
usefulness of type hints for documentation purposes. Still, it's an
extremely quick fix.
(3) Reimplement doc <--> definition correlation directly in schema.py,
integrating doc fields directly into QAPISchemaMember and relieving
the QAPIDoc class of the responsibility. Users of the information
would instead visit the members first and retrieve their
documentation instead of the inverse operation -- visiting the
documentation and retrieving their members.
My preference is (3), but in the short-term (1) is the easiest way to
have my cake (strong type hints) and eat it too (Not have import
cycles). Do (1) for now, but plan for (3).

Here's the weird bit. QAPIDoc generally expects -- virtually everywhere
-- that it will always have a current section. The sole exception to
this is in the case that end_comment() is called, which leaves us with
*no* section. However, in this case, we also don't expect to actually
ever mutate the comment contents ever again.
NullSection is just a Null-object that allows us to maintain the
invariant that we *always* have a current section, enforced by static
typing -- allowing us to type that field as QAPIDoc.Section instead of
the more ambiguous Optional[QAPIDoc.Section].
end_section is renamed to switch_section and now accepts as an argument
the new section to activate, clarifying that no callers ever just
unilaterally end a section; they only do so when starting a new section.

The "if self._section" clause in end_section is mysterious: In which
circumstances might we end a section when we don't have one?
QAPIDoc always expects there to be a "current section", only except
after a call to end_comment(). This actually *shouldn't* ever be 'None',
so let's remove that logic so I don't wonder why it's like this again in
three months.

True, we do not check the validity of this symbol -- but we don't check
the validity of definition names during parse, either -- that happens
later, during the expr check. I don't want to introduce a dependency on
expr.py:check_name_str here and introduce a cycle.
Instead, rest assured that a documentation block is required for each
definition. This requirement uses the names of each section to ensure
that we fulfilled this requirement.
e.g., let's say that block-core.json has a comment block for
"Snapshot!Info" by accident. We'll see this error message:
In file included from ../../qapi/block.json:8:
../../qapi/block-core.json: In struct 'SnapshotInfo':
../../qapi/block-core.json:38: documentation comment is for 'Snapshot!Info'
That's a pretty decent error message.
Now, let's say that we actually mangle it twice, identically:
../../qapi/block-core.json: In struct 'Snapshot!Info':
../../qapi/block-core.json:38: struct has an invalid name
That's also pretty decent. If we forget to fix it in both places, we'll
just be back to the first error.
Therefore, let's just drop this FIXME and adjust the error message to
not imply a more thorough check than is actually performed.

The assertion fails when a command or event is redefined with a

Recently, Coverity has started complaining about using g_free() to free
memory areas allocated by GLib functions not included in model.c,
such as g_strfreev. This unfortunately goes against the GLib
documentation, which suggests that g_malloc() should be matched
with g_free() and plain malloc() with free(); since GLib 2.46 however
g_malloc() is hardcoded to always use the system malloc implementation,
and g_free is just "free" plus a tracepoint. Therefore, this
should not cause any problem in practice.

We can invoke the shell history writing when we leave the QMPShell scope
instead of relying on atexit. Doing so may be preferable to avoid global
state being registered from within a class instead of from the
application logic directly.
Use QMP's context manager to hook this history saving at close time,
which gets invoked when we leave the context block.

I'm only doing a very quick best-effort to preserve this script, to help
keep it from breaking further. I think there are pending ideas swirling
on the right way to implement better SDKs and better clients, and this
script might be a handy reference for those discussions. It presents
some interesting design problems, like static type safety when using a
dynamic RPC mechanism.
I believe it's worth preserving the effort and care that went into
making this script by updating it to work with our current
infrastructure. However, I am disabling the requirement for docstrings
in this file.
If you would like to help improve this script, please add docstrings
alongside any refactors or rejuvenations you might apply at that time.

Because fusepy does not have type hints, add some targeted warning
suppressions.
Namely, we need to allow subclassing something of an unknown type (in
qom_fuse.py), and we need to allow missing imports (recorded against
fuse itself) because mypy will be unable to import fusepy (even when
installed) as it has no types nor type stubs available.
Note: Until now, it was possible to run invocations like 'mypy qemu/'
from ./python and have that work. However, these targeted suppressions
require that you run 'mypy -p qemu/' instead. The correct, canonical
invocation is recorded in ./python/tests/mypy.sh and all of the various
CI invocations always use this correct form.

Redirect to the new qom scripts. These forwarders can be deleted
eventually when there has been more time for the dust on the Python
packaging to settle and people understand how to find these commands.
Note: You can run these by setting $PYTHONPATH in your shell and then
running "python3 -m qemu.qmp.qom", or you can install the qemu namespace
package and use the "qom" or "qom-set" scripts.
I've written how to install the package elsewhere, but for the sake of
git-blame, cd to ./python, and then do:
- pip3 install [--user] [-e] .
--user will install to your local user install (will not work inside of
a venv), omitting this flag installs to your system-wide packages
(outside of a venv) or to your current virtual environment (inside the
venv).
When installing to a venv or to your system-wide packages, "qom"
should be in your $PATH already. If you do a user install, you may
need to add ~/.local/bin to your $PATH if you haven't already.
-e installs in editable mode: the installed package is effectively just
a symlink to this folder; so changes to your git working tree are
reflected in the installed package.
Note: installing these packages to an environment outside a venv can be
dangerous: Many QEMU scripts will begin to prefer the installed version
instead of the version directly in the tree. Use with caution. editable
mode is recommended when working outside of a venv.

TypeGuards wont exist in Python proper until 3.10. Ah well. We can hack
up our own by declaring this function to return the type we claim it
checks for and using this to safely downcast object -> List[str].
In so doing, I bring this function under _pragma so it can use the
'info' object in its closure. Having done this, _pragma also now no
longer needs to take a 'self' parameter, so drop it.
To help with line-length, and with the context evident from its new
scope, rename the function to the shorter check_list_str().

Fixes: f5d4361cda
Fixes: 52a474180a
Fixes: 46f49468c6
Remove the try/except block that handles file-opening errors in
QAPISchemaParser.__init__() and add one each to
QAPISchemaParser._include() and QAPISchema.__init__() respectively.
This simultaneously fixes the typing of info.fname (f5d4361cda), A
static typing violation in test-qapi (46f49468c6), and a regression of
an error message (52a474180a).
The short-ish version of what motivates this patch is:
- It's hard to write a good error message in the init method,
because we need to determine the context of our caller to do so.
It's easier to just let the caller write the message.
- We don't want to allow QAPISourceInfo(None, None, None) to exist. The
typing introduced by commit f5d4361cda types the 'fname' field as
(non-optional) str, which was premature until the removal of this
construct.
- Errors made using such an object are currently incorrect (since
52a474180a)
- It's not technically a semantic error if we cannot open the schema.
- There are various typing constraints that make mixing these two cases
undesirable for a single special case.
- test-qapi's code handling an fname of 'None' is now dead, drop it.
Additionally, Not all QAPIError objects have an 'info' field (since
46f49468), so deleting this stanza corrects a typing oversight in
test-qapi introduced by that commit.
Other considerations:
- open() is moved to a 'with' block to ensure file pointers are
cleaned up deterministically.
- Python 3.3 deprecated IOError and made it a synonym for OSError.
Avoid the misleading perception these exception handlers are
narrower than they really are.
The long version:
The error message here is incorrect (since commit 52a474180a):
> python3 qapi-gen.py 'fake.json'
qapi-gen.py: qapi-gen.py: can't read schema file 'fake.json': No such file or directory
In pursuing it, we find that QAPISourceInfo has a special accommodation
for when there's no filename. Meanwhile, the intent when QAPISourceInfo
was typed (f5d4361cda) was non-optional 'str'. This usage was
overlooked.
To remove this, I'd want to avoid having a "fake" QAPISourceInfo
object. I also don't want to explicitly begin accommodating
QAPISourceInfo itself being None, because we actually want to eventually
prove that this can never happen -- We don't want to confuse "The file
isn't open yet" with "This error stems from a definition that wasn't
defined in any file".
(An earlier series tried to create a dummy info object, but it was tough
to prove in review that it worked correctly without creating new
regressions. This patch avoids that distraction. We would like to first
prove that we never raise QAPISemError for any built-in object before we
add "special" info objects. We aren't ready to do that yet.)
So, which way out of the labyrinth?
Here's one way: Don't try to handle errors at a level with "mixed"
semantic contexts; i.e. don't mix inclusion errors (should report a
source line where the include was triggered) and command line errors
(where we specified a file we couldn't read).
Remove the error handling from the initializer of the parser. Pythonic!
Now it's the caller's job to figure out what to do about it. Handle the
error in QAPISchemaParser._include() instead, where we can write a
targeted error message where we are guaranteed to have an 'info' context
to report with.
The root level error can similarly move to QAPISchema.__init__(), where
we know we'll never have an info context to report with, so we use a
more abstract error type.
Now the error looks sensible again:
> python3 qapi-gen.py 'fake.json'
qapi-gen.py: can't read schema file 'fake.json': No such file or directory
With these error cases separated, QAPISourceInfo can be solidified as
never having placeholder arguments that violate our desired types. Clean
up test-qapi along similar lines.

add types to the QAPISchemaParser. Callers don't need to know the
details of QAPIParseError unless they are parsing or dealing directly
with the parser, so this won't create any harsh new requirements for
callers in the general case.
Update error.py with a little docstring that gives a nod to where the
error may now be found.

Built-in stuff is not parsed from a source file, and therefore have no
QAPISourceInfo. If such None info was used for reporting an error,
built-in stuff would be broken. Programming error. Instead of reporting
a confusing error with bogus source location then, we better crash.
We currently crash only if self.col was set. Assert that self.info is
not None in order to crash reliably.
We can not yet change the type of the initializer to prove this cannot
happen at static analysis time before the remainder of the code is fully
typed.

It's already treated as optional, with one direct caller and some
subclass callers passing 'None'. Make it officially optional, which
requires moving the position of the argument to come after all required
parameters.
QAPISemError becomes functionally identical to QAPISourceError. Keep the
name to preserve its semantic meaning and avoid code churn, but remove
the now-useless __init__ wrapper.

Rename QAPIError to QAPISourceError, and then create a new QAPIError
class that serves as the basis for all of our other custom exceptions,
without specifying any class properties.
This leaves QAPIError as a package-wide error class that's suitable for
any current or future errors.
(Right now, we don't have any errors that DON'T also want to specify a
Source location, but this MAY change. In these cases, a common abstract
ancestor would be desired.)
Add docstrings to explain the intended function of each error class.

Per list review: qapi-code-gen.txt reserves suffixes Kind and
List only for type names, but the code rejects them for events and
commands, too.
It turns out we reject them earlier anyway: In check_name_upper() for
event names, and in check_name_lower() for command names.
Still, adjust the code for clarity over what precisely we are guarding
against.

This is a small rewrite to address some minor style nits.
Don't compare against the empty list to check for the empty condition, and
move the normalization forward to unify the check on the now-normalized
structure.
With the check unified, the local nested function isn't needed anymore
and can be brought down into the normal flow of the function. With the
nesting level changed, shuffle the error strings around a bit to get
them to fit in 79 columns.
Note: although ifcond is typed as Sequence[str] elsewhere, we *know* that
the parser will produce real, bona-fide lists. It's okay to check
isinstance(ifcond, list) here.

This is a minor adjustment that lets parameters @required and
@optional take tuple arguments, in particular (). Later patches will
make use of that.
(Iterable would also have worked, but Iterable also includes things like
generator expressions which are consumed upon iteration, which would
require a rewrite to make sure that each input was only traversed
once. Collection implies the "can re-iterate" property.)

Casts are instructions to the type checker only, they aren't "safe" and
should probably be avoided in general. In this case, when we perform
type checking on a nested structure, the type of each field does not
"stick".
(See PEP 647 for an example of "type narrowing" that does "stick".
It is available in Python 3.10, so we can't use it yet.)
We don't need to assert that something is a str if we've already checked
or asserted that it is -- use a cast instead for these cases.

Prior to this commit, specifying a non-object value here causes the QAPI
parser to crash in expr.py with a stack trace with (likely) an
AttributeError when we attempt to call that value's items() method.
This member needs to be an object (Dict), and not anything else. Add a
check for this with a nicer error message, and formalize that check with
new test cases that exercise that error.
