5f32c9edce tst_QTimer: suppress the cross-thread timer stopping warnings
Both QTimer's and QObjectPrivate's destructors print a warning if the
current object lives on another thread and has an active timer:

QWARN  : tst_QTimer::moveToThread() QObject::killTimer: Timers cannot be stopped from another thread
QWARN  : tst_QTimer::moveToThread() QObject::~QObject: Timers cannot be stopped from another thread

This timer is used to ask the thread to quit, which in turn allows us to
destroy this QObject without a cross-thread warning. Because it's
already fired once and done its duty, we can make sure it's not active
by simply making it single-shot.

b124171309 QObjectBindableProperty: Avoid use-after-free in notifyObservers
We so far refetched the first observer after evaluating bindings, as
binding evaluating might change the list of observers.
However, that approach did not take into account that the 'this' pointer
might no longer be valid after binding evaluation: In case of a
QObjectBindableProperty (or a QObjectCompatProperty), binding evaluation
might cause a reallocation of the binding storage, and consequently the
invalidation of the QPropertyBindingData.
Fix this by refetching the QPropertyBindingData from the storage (if a
storage has been provided, which is always the case for the affected
classes).

9483fcd68a QObject: Handle pointers to incomplete types in auto-connections
The code for the QMetaMethod queuedConnectionTypes overload relied on
QMetaMethod::parameterMetaType and QMetaType::flags() to detect whether
we're dealing with a pointer (and then use the VoidStar metatype instead).
However, if the type was incomplete when the slot was defined, and the
type was not registered when connect was called, we would not find a
metatype for the argument.
However, in that case we might still be able to handle the method, by
checking whether the type name of the arguments ends with a "*".
This patch does that, fixing a regression from 5.15.

66a1a71f1f Fix QVariant(QString) <-> enum conversion
A QVariant(QString) was not convertible to an enum not registered with
Q_ENUM() which worked fine in Qt5.
The same problem exists for QVariant(enum) to QString.
Fix it by not bailing out when no metatype for the enum was found and

converted to the enum type).

7a415a051a Avoid accessing deleted binding data in grouped updates
This fixes a use-after-free in QPropertyDelayedNotifications::notify.

Before this patch, evaluateBindings or a notify from a property index
might have caused the originalBindingData to become reallocated.
However, at that point, we've already restored the original bindingData
in evaluateBindings, so we won't track updates, and thus won't adjust
originalBindingStatus, which will then point to already freed data.

To remedy this, we no longer do the notification with data fetched from
originalBindingData, but instead use the information we have in the
proxyData.
We also need to enure that referenced bindings do not get deleted; for
that we keep the PendingBindingObserverList alive for the whole duration
of the endPropertyUpdateGroup.

As we now have the PendingBindingObserverList, we use it for the
notification logic, and only notify change handlers in
QPropertyDelayedNotifications::notify. That will allow a follow-up
cleanup of QPropertyObserverPointer::notify, and aligns the logic for
grouped updates with the logic for "nornal", non-grouped updates.

Amends f1b1773d0a.

with values ReadOnly and ReadWrite is much easier, and will also lend

ce104cac50 QPermission: replace T data<T>() with std::optional<T> value<T>()
As discussed in API review, the default-constructed T() returned from
a mismatched data<T>() call is indistinguishable from a real T with
default state.

To make them distinguishable, return optional<T>. Call the new
function value<T>(), mimicking QVariant::value<T>(), and suggested in
API review, because data() is usually used to return raw pointers, not
values.

Remove the qWarning() on requestedType and actualType mismatch, as the
new function can be used in std::get_if/dynamic_cast-like if-then-else
chains, in which failure is part of the normal operation, and a
warning message misplaced:

  if (auto loc = perm.value<QLocationPermission>())
     ~~~ use *loc ~~~
  else if (auto con = perm.value<QContactsPermission>())
     ~~~ use *con ~~~
  ~~~ etc ~~~

e8f5f20319 QMetaType: fix value-initialization in a corner case
If a type is trivially default constructible, QMetaType (and QVariant)
think that it can be built and value-initialized by zero-filling a
region of storage and then "blessing" that storage as an actual instance
of the type to build. This is done as an optimization.

This doesn't work for all trivially constructible types. For instance,
on the Itanium C++ ABI, pointers to data members are actually
value-initialized (= zero-initialized, = initialized to null) with the
value -1:

https://itanium-cxx-abi.github.io/cxx-abi/abi.html#data-member-pointers

This means that a type like

  struct A { int A::*ptr; };

is trivially constructible, but its value initialization is not
equivalent to zero-filling its storage.

Since C++ does not offer a type trait we can use for the detection that
we want to do here, and since we have also decided that Q_PRIMITIVE_TYPE
isn't that trait (it just means trivially copyable / destructible), I'm
rolling out a custom type trait for the purpose.

This type trait is private for the moment being (there's no
Q_DECLARE_TYPEINFO for it), and limited to the subset of scalar types
that we know can be value-initialized by memset(0) into their storage
(basically, all of them, except for pointers to data members).

The fix tries to keep the pre-existing semantics of
`QMetaType::NeedsConstruction`. Before, the flag was set for types which
were not trivially default constructible. That included types that
aren't default constructible, or types that cannot do so trivially.
I've left that meaning unchanged, and simply amended the "trivial" part
with the custom trait. A fix there (to clarify the semantics) can be
done as a separate change.

The code implementing the C++ rules of type promotion and conversion

So we can reduce this to fewer comparisons and fewer rules, using the
size of the type, not just the type ID.

e2fef733be Replace usages of Q_CLANG_QDOC with Q_QDOC
To allow the user to customize the C++ code that QDoc sees, so as to be
able to work-around some limitations on QDoc itself, QDoc defines two
symbols: Q_QDOC and Q_CLANG_QDOC, both of which are "true" during an
entire execution of QDoc.

At a certain point in time, QDoc allowed the user the choice between a
custom C++ parser and a Clang based one.

The Q_QDOC symbol would always be defined while the Q_CLANG_QDOC symbol
would be defined only when the Clang based parser was chosen.

In more recent times, QDoc always uses a Clang based parser, such that
both Q_CLANG_QDOC and Q_QDOC are always defined, making them equivalent.

To avoid using different symbols, and the possible confusion and
fragmentation that derives from it, all usages of Q_CLANG_QDOC are now
replaced by the equivalent usages of Q_QDOC.

aa37e67ef7 Port from qAsConst() to std::as_const()
We've been requiring C++17 since Qt 6.0, and our qAsConst use finally
starts to bother us (QTBUG-99313), so time to port away from it
now.

Since qAsConst has exactly the same semantics as std::as_const (down
to rvalue treatment, constexpr'ness and noexcept'ness), there's really
nothing more to it than a global search-and-replace, with manual
unstaging of the actual definition and documentation in dist/,
src/corelib/doc/ and src/corelib/global/.

2ef130a41d JNI: add generic support for array-types
The typeSignature for a type T[] is always "[" + typeSignature<t>, so we
can just implicitly support arrays of any known type. To prevent support
for multi-dimensional arrays, make sure that the underlying type is not
also an array.

By adding a QJniTypes::isArrayType in addition (that is true for any
type with a signature starting with '['), methods like
QJniObject::callMethod could then return a special QJniArray type that
provides array-specific functionality.

As a drive-by, and since all lines need to be touched to add braces,
replace std::is_same<>::value with std::is_same_v.

1e625033be tst_QSharedMemory: remove mention of gravlaks.troll.no
It was our old, HP-UX machine on Itanium (ran on big-endian mode). We
don't support HP-UX any more; HP will still support the 11i v3 release
until 2025, but I doubt anyone wants to run any new software there. One
hopes that HP has long since fixed the issue, but I doubt it since the
last release is from 2007. Gravlaks probably ran HP-UX 11i v3.

There are a couple other left-overs of ".troll.no" in the repository,
the majority of which are URL manipulation in tst_qurl.cpp and in
tst_qnetworkcookie.cpp, then the certificates for fluke.troll.no (valid
until 2035) and aspiriniks.troll.no (expired in 2009, but we don't need
it for validity).

7a7051b58f QMetaType: Support custom unary converters with optional<To> return type
To indicate success of a conversion, the public API has previously only
supported registering member functions of the form To (From::*)(bool *).
When adding custom converters for types that cannot be modified, this is
usually not a possibility.
As an alternative, this patch adds support for std::optional in the
UnaryFunction overload of QMetaType::registerConverter. If the returned
optional has no value, the conversion is considered failed.

40523b68c1 QWinRegistryKey: refactor
Refactor QWinRegistryKey to make it more modern and more
usable from outside.

Adjust the test for QWinRegistryKey to test the new functions,
merged with the original test.

Will port raw registry accessing code in QtBase to use this
class in follow-up commits. This change is the first step.

The long term goal is to port QSettings registry code to
this class instead of using raw Win32 APIs, however, there's
much more registry code in QSettings and migrate them to this
class needs a large refactor, so jsut leave it for now. Will
fix it in some future commit.

0380dd5051 QMetaObject: pass the QMetaTypes in variadic invoke/newInstance
[ChangeLog][QtCore][Meta Object] QMetaMethod::invoke(),
QMetaObject::invokeMethod(), and QMetaObject::newInstance() are no
longer limited to 10 arguments.

[ChangeLog][QtCore][Meta Object] The use of the Q_ARG macro is no longer
necessary when using QMetaMethod::invoke(), QMetaObject::invokeMethod(),
and QMetaObject::newInstance(). Types may now be passed
directly. Similarly, Q_RETURN_ARG can be replaced by the free function
qReturnArg().

[ChangeLog][Potentially Source-Incompatible Changes]
QMetaMethod::invoke(), QMetaObject::invokeMethod(), and
QMetaObject::newInstance() no longer support passing forward-declared
types in the argument list (it was possible to pass them by
const-ref). From Qt 6.5 onwards, all types in the argument list must be
fully defined.

[ChangeLog][Potentially Source-Incompatible Changes] Attempting to use
the internal types QArgument, QReturnArgument, QGenericArgument, or
QGenericReturnArgument directly with QMetaMethod::invoke(),
QMetaObject::invokeMethod() or QMetaObject::newInstance() may fail to
compile. Those are internal types that were never meant to be used
directly and will be removed in Qt 7. If really necessary, ensure all
arguments passed to those functions are directly using those classes and
not mixed with Q_ARG and Q_RETURN_ARG. Implementations of bindings to
other languages should contact the Qt development mailing list to
discuss options.

95542b386a tst_qobject: port away from deprecated methods
The patch includes the following replacements:
* QMetaType::type("name") -> QMetaType::fromType<Type>().id()
* QMetaProperty::type() -> QMetaProperty::typeId()
* QVariant::Type -> QMetaType::Type
* qRegisterMetaType<T>("name") -> qResigeterMetaType<T>()
* The static QMetaType::{load,save} methods are replaced with
  non-static versions
* Replace QCOMPARE(property.type(), QVariant::UserType) with
  QCOMPARE_GT(property.typeId(), QMetaType::User), because the
  deprecated type() method was treating each custom type
  (id >= QVariant::UserType) as QVariant::UserType, while the
  typeId() method simply returns the actual id.

As a drive-by: remove unneeded QMetaType registration tests
as we have tst_QMetaType to check it.
