Alexey Edelev 815bc61626 Cleanup tests that add test data to resources explicitly
Remove Integrity and Android specific code that explicitly adds
test data to the resource files. qt_internal_add_test functions
implicitly adds test data to resources for Android and Integrity
platforms by default.

Multiple tests use qt_internal_add_resource that copies the

Alex Trotsenko 9f6f3da8eb tst_qeventdispatcher: avoid influence between test functions
When some test function fails (even as expected), it can leave the
event dispatcher in an inconsistent state where the posted events
queue might not be empty. As a result, this may break the internal
logic of the next test function that is run.

So, calling eventDispatcher->processEvents() after each completed
function resets the event dispatcher to its initial state, which
fixes the problem.

Volker Hilsheimer d671bab0e3 Win32: always allow the event loop to be woken up by posted events
We set the wakeUps atomic to prevent multiple WM_QT_SENDPOSTEDEVENTS from
being posted. However, this might happen right after the event processing
thread cleared the atomic, but before it processed the previous
WM_QT_SENDPOSTEDEVENTS message. In that case, we end up with a set
atomic  and an empty event queue, resulting in the event loop to block
even though there are posted QEvents.

To prevent that, always reset the atomic when we handle the
WM_QT_SENDPOSTEDEVENTS message. In that case, we either call
sendPostedEvents, or startPostedEventsTimer. The former already resets
wakeUps; reset it in the latter as well.

Volker Hilsheimer d292f0143f Add more tests for event dispatcher waking up
Add two tests for some problematic scenarios where the behavior is not
consistent across platforms and depending on which event dispatcher is
used:

1) reliably waking up the dispatcher when posting events from a worker
thread.

That test fails 100% of the time on Windows no matter what type of
application is created. It passes reliably on Linux and macOS for both
core and gui applications.

2) waking up the dispatcher when we post an event from within an
event handler.

That test fails 100% of the time on Windows, both with core
and GUI event dispatchers. On macOS, the test fails 100% of the time
with the core dispatcher, and passes 100% of the time with the GUI
dispatcher. On Linux, it passes only if a Glib based event dispatcher
is used; the default Unix event dispatcher (which is also the one
used on macOS for core applications) fails.

Marc Mutz 58058794b1 tst_qmetatype: fix memleaks
We didn't delete the new'ed up QMetaTypeInterfaces, causing asan to
complain.

Fix by storing them in strong references alongside their users in a
statically-allocated container.

We use shared_ptr to hold them, because QMetaTypeInterface doesn't
have a virtual destructor, so deleting objects of the TypeInfo types
(plural!) derived from QMetaTypeInterface though a pointer to the base
class is UB. The shared_ptr constructor, however, is templated, so it
stores the correct call (~TypeInfo()) in its type-erased deleter.

We can't use std::make_shared(), because that doesn't support
aggregate initialization until C++20, so we manually new up the
TypeInfos.

5.15 is not affected.

Marc Mutz f898128ee2 tst_qmetatype: factor the most expensive test into its own TU
The PRINT_2ARD_TEMPLATE macro expansion alone is responsible for about
50% of the compile time and RAM requirements of tst_qmetatype.cpp. By
factoring it into its own TU, we reduce the maximum memory load on my
machine from 4.0GiB to 2.5GiB, provided we don't parallelize the
build, then we take 0.5GiB more.

This is a quick-fix for the QNX build problems currently plaguing the
CI. Going forward, we should probably have a better solution, whatever
that may be.

Thiago Macieira 0e72a846d3 QObject: Q_ASSERT the object type before calling a PMF
The old-syle signal-slot syntax had the advantage of not delivering
signals to slots in derived classes after that derived class's
destructor had finished running (because we called via the virtual
qt_metacall). The new syntax made no checks, so a conversion from the
old to the new syntax may introduce crashes or other data corruptions at
runtime if the destructor had completed.

This commit introduces a Q_ASSERT to print the class name that the
object is not any more. Since this is in inline code, this should get
enabled for users' debug modes and does not therefore depend on Qt being
built in debug mode.

It required some Private classes to be adapted to the new form, by
exposing the public q_func() in the public: part.

Giuseppe D'Angelo 7d4d47de70 QObject::connect(): fail to connect to a functor if UniqueConnection is passed
The connect() documentation makes it clear that UniqueConnection does
not work with free functions / function objects and the like; only with
actual PMFs. Rather than silently *ignoring* the flag, be vocal about its
presence by warning, and make the connection fail (as the user has
passed an illegal argument).

[ChangeLog][QtCore][QObject] QObject::connect() now will refuse to
connect a signal to a free function / function object if UniqueConnection
is passed. Note that UniqueConnection has never worked for such
connections -- the flag was simply ignored, and they were established
multiple times. Now, the flag is not ignored and results in a connection
failure (as well as a runtime warning by Qt).

Fabian Kosmale e4d62651c2 Re-add QPropertyAlias functionality
As QPropertyAlias was public by accident in 6.0, we have to ensure that
it still works in 6.2.
This re-adds some tests for it, and reimplements the unlinking
functionality. To avoid performance regressions in hot-paths,
a new unlink_fast function is added, which behaves like the old unlink:
It ignores the special handling for QPropertyAlias, so that we can skip
the tag check. It is only used in QPropertyObserverNodeProtector and
clearDependencyObservers, where we already know the type of the
observer.

Marc Mutz 2b50c8bec0 QObject: optimize the common case of findChildren(QString())
Outside tests, all in-tree callers of QObject::findChildren() pass no
name to match, and in my experience that is also true for the vast
majority of out-of-tree users.

Avoid the temporary QString creation in the caller and the repeated
QString::isNull() checks in the implementation by overloading
findChildren() without a name argument and checking for name.isNull()
only once, forking off into separate helper functions.

Adjust in-tree callers that used an explicit `QString()` argument in
order to pass options, which goes to show that `name` should never
have been the first argument of findChilden() in the first place, even
though I appreciate the symmetry with findChild() (the use-cases of
which, however, are radically different).

Change a `findChildren().size() == 0` call found while scanning for
findChildren() calls to `!findChild()` as a drive-by.

Modernize loops in the various qt_qFindChild{,ren}_helper() overloads
to match how the new code looks.

name (thus optimizing this common case).

Tor Arne Vestbø 9661cde161 Apple: Use POSIX IPC instead of System V in sandboxed applications
System V semaphores are not supported in sandboxed applications,
so when Qt is configured with App Store compliance, or the user
requests POSIX IPC explicitly, we use that instead.

https://developer.apple.com/library/archive/documentation/Security/Conceptual/AppSandboxDesignGuide/AppSandboxInDepth/AppSandboxInDepth.html#//apple_ref/doc/uid/TP40011183-CH3-SW24

As the shared memory name limit on Apple platforms is very low,
we have to skip the existing logic for naming, and instead use
a truncated hash of the key. This should still be fine for
avoiding any collisions in practice.

An explicit check for the ENAMETOOLONG error has been added to
catch any cases where they key goes beyond the allowed length.

Sandboxed applications also have an extra requirement that the
key must include an application group identifier. This requirement
has been pushed up to the user and documented, as we don't have
enough information in Qt to know which identifier to use.

Both tst_QSystemSemaphore and tst_QSharedMemory work as before
with both sandboxed and non-sandboxed applications, after removing
some assumptions in tst_QSharedMemory about System V behavior.

QPropertyChangeHandler is a templated class and it's argument is

Introduce a QPropertyNotifier class that stores the functor

Also make QPropertyNotifier default constructible.

Fabian Kosmale 5b681bea90 QPropertyBinding: Do not reevaluate if not installed on property
Since we changed binding evaluation to be always eager, we notify and
evaluate all bindings as soon as any dependency changes. This includes
bindings which have been initially installed on a property, but which
were later removed.
With lazy evaluation, we would only notify those bindings and mark them
as dirty, which is unproblematic. With eager evalution, we attempt to
evaluate the binding, though. While that part is still fine, afterwards
we would attempt to write the new value into the property. However,
there is no property at that point, as the binding is not installed.
Instead of adding a check whether the propertydataptr is null, we skip
the reevaluation completely by removing the bindings observers - and
thus the cause for the binding function's reevaluation. As soon as the
binding is set, we reevaluate the function anyway, at which point we
also capture the observers again.

Too much of the existing code in Qt requires eager evaluation without

This does not diminish other benefits of the new property system, which
include

- faster execution compared to QML's existing bindings and the ability

Fabian Kosmale cb43aaca11 Introduce QMetaObject::metaType
This function returns the metatype corresponding to the metaobject, or
an invalid metatype for namespaces.

This works as follows: First we increment the metaobject revision for
new metaobjects. Metaobjects with older revisions are handled by doing a
lookup by name. That fallback is also used for dynamic metaobjects (from
QtDBUS and those created by QMetaObjectBuilder).
For new metaobjects, we store the metatype in its metatype array, behind
the property metatypes. This avoids any changes to the property and
method metatype extraction logic: For properties, the metatype access
does not change, as the new metatype is after their metatypes. For
method metatypes, we already have an indirection layer (using offsets),
so by adjusting those offsets by one, the same logic keeps working.

To distinguish between namespaces and dynamic metaobjects, namespaces
store the metatypeinterface pointer for void in the metatype array,
whereas dynamic metaobjects store a nullptr.

One nice additional benefit is that this simplifies the generator logic
in moc, as the metatype array is now never empty.

Mårten Nordheim f274f91ceb QEventDispatcher(Win): Always honor interrupted status to avoid races
There may be a race where e.g. thread 'B' is woken up by a queued invoke.
At the same time thread 'A' asks 'B' to quit, which will set various
atomics (some important ones are 'interrupt' in the dispatcher and
'exit' in the event loop), but it does _not_ try to send another wake
since there is already an unhandled wake triggered by 'B' itself.
Sadly 'B' reads the 'exit' atomic before 'A' updates it.
Then, slightly before, 'B' sets 'interrupt' back to 0, 'A' write 1 to
it, meaning 'A's interrupt is ignored. Then, since there is no
interrupt, 'B' goes back to waiting for events, leaving the thread alive
and running instead of quitting.

Maybe this has unforeseen consequences (one consequence is that it will
return and re-enter the event dispatcher once more, possible
unnecessarily)

const away; but so does C++ with const_cast.
In addition, a new flag, QMetaType::IsImmutable is introduced, and used

discern between pointers to mutable and const QObjects, which is
relevant for the QML engine.

results in a binding loop warning when the tap handler triggers. While
the change handler would only run once, we cannot statically determine
if we need to loop once, twice, or if there actually is a diverging
loop. Thus we unconditionally warn about the binding loop and stop
executing the binding.

To optimize certain operations, it can be useful to know whether we are

also allocate them if they are used in a binding context, as we would
otherwise not properly track the dependency. Using
isAnyBindingEvaluating in the getter, we can detect this
situation, and avoid the allocation if it returns false.

This API is private for now, as it exposes some internals of the

Alex Trotsenko 6dac45b246 QSocketNotifier: extend API to provide more flexible startup
Technically, having a single constructor limits the use-cases for this
class. We should take into account that:

  - an opened socket descriptor must be available at the moment of
    construction;
  - the constructor unconditionally enables the notifier (the possible
    solution

        notifier = new QSocketNotifier(...);
        notifier->setEnabled(false);

    is suboptimal due to heavy operations inside the event dispatcher);
  - for these reasons, QSocketNotifier most often cannot be a member of
    another class (we have an extra allocation and indirect access).

This patch addresses this shortcoming by making it possible to set the
socket descriptor at a later point:

[ChangeLog][QtCore][QSocketNotifier] Added setSocket() and an additional
constructor which requires no socket.

Giuseppe D'Angelo 405244fe30 Fix QVariant/QMetaType::compare APIs
std::optional<int> is the wrong datatype to use for compare.

First and foremost, it can't be used in the idiomatic form of

  auto r = a.compare(b);
  if (r < 0) ~~~ // a is less than b
  if (r > 0) ~~~ // a is greater than b

which we *already* feature in Qt (QString, QByteArray).

Also, std::optional<int> (explicitly) converts to bool, which is
a trap, because the result of the comparison can be accidentally
tested as a bool:

  if (a.compare(b)) ~~~ // oops! does NOT mean a<b

Not to mention extending this to algorithms:

  auto lessThan = [](QVariant a, QVariant b) { return a.compare(b); }; // oops!
  std::ranges::sort(vectorOfVariants, lessThan);

which thankfully doesn't compile as is -- std::optional has
an *explicit* operator bool, and the Compare concept requires an
implicit conversion. However, the error the user is going to face
will be "cannot convert to bool because the operator is explicit",
which is deceiving because the fix is NOT supposed to be:

  auto lessThan = [](QVariant a, QVariant b) { return (bool)a.compare(b); }; // big oops!

Instead: backport to Qt the required subset of C++20's <compare>
API, and use that. This commits just adds the necessary parts
for compare() (i.e. partial ordering), the rest of <compare>
(classes, functions, conversions) can be added to 6.1.

The other problem to solve where undefined references to metaobjects. The

Fabian Kosmale c1c991c319 Remove std::function from QProperty interface
std::function as a type is rather unfortunate for us, as its SSO buffer
makes it rather large, and we can ensure that the function is never
empty.
Considering that we do need to allocate memory for
QPropertyBindingPrivate anyway, we can get rid of the SSO buffer and
instead coalesce the allocations (similar to how std::make_shared works).
The memory looks then like
[--QPropertyBindingPrivate--][Functor]
and QPropertyBindingPrivate can get a pointer to the functor via
reinterpret_cast<std::byte>(this)+sizeof(QPropertyBindingPrivate).
To actually do anything with the functor, we do however need a "vtable"
which describes how we can call, destroy and move the functor. This is
done by creating a constexpr struct of function pointers, and storing a
pointer to it in QPropertyBindingPrivate.

As a consequence of those changes, we cannot use QESDP anymore, as we
now have to carefully deallocate the buffer we used for both the
QPropertyBindingPrivate and the functor. We introduce a custom
refcounting pointer for that. While we're at it, we make the refcount
non-atomic, as bindings do not work across threads to begin with.

Moreover, we can now make the class non-virtual, as that was only needed
to hack around limitations of QESDP in the context of exported symbols.
