1f1a322373 Simplify the safeguarding logic in notify()
The logic in notify() was doing quite a bit more work than
it needed to. By inserting a dummy node after the current one instead of
replacing it, we can avoid half of the data shuffling that has been
happening and also don't need a back pointer when executing the
notification.

Also avoid calling a semi expensive destructor of QPropertyObserver.

Reduces the overhead of notify() by ~30%.

b71c04353d CMake: Work around building dbus 'controller' example with qmake
Similar to what has been done in 5138a970f3, we need to adjust the
remotecontrolledcar/controller dbus example to be built with qmake.

In the CI we first build the examples with CMake in the source
directory. That creates some generated source files in the dbus example
dir.

Then, the examples are (will be) built ouf of source with qmake, and
those generated source files will be placed in the build directory.

When building with MSVC, there's a peculiarity with nmake/jom's
inference rules that lead to picking up the generated car_interface.cpp
from the source directory, instead of the build directory.
See QTBUG-13496 for details.

car_interface.cpp, built with CMake is generated to include
car_interface.moc.
car_interface.cpp, built with qmake does not have this include, but the
build system calls moc on car_interface.h.

All this leads to duplication of the meta object for
OrgExampleExamplesCarInterfaceInterface, preventing successful linking.

Work around this issue by turning off the generation of nmake/jom
inference rules.

1158ff67b4 QSslSocket::verify: do not alter the default configuration
QSslCertificate::verify() has an undocumented and not very desirable property -
on some platorms it updates the default configuration, which can be surprising.
For example, we deprecated QSslSocket::setDefaultCaCertificates() and recommend
using QSslConfiguration::defaultConfiguration(), QSslConfiguration::setDefaultConfiguration(),
and QSslConfiguration::setCaCertificates(). If an application does this to select
CA roots it trusts explicitly, and then for some reason is calling verify, the
application can have its QSslSockets successfully connecting to a host, whose
root was not trusted by the application. Also, on Windows, defaultCaCertificates()
include system roots already, no need to have them twice.

dbd1c8b047 Let QXcbConnection::getTimestamp properly exit when X server quits
QXcbConnection::getTimestamp uses dummy events to get timestamp from
X server. However, in some cases, X server shuts down while client tries
to get timestamp. In this case, QXcbConnection::getTimestamp keeps
getting null event and thus falls into indefinite loop.

This fix checks if xcb connection is still valid and use a special
xcb_timestamp_t value, CurrentTime (0L), as returned value.
CurrentTime should not be generated by X server and if getTimestamp
returns this value, it means an "exception" case is triggered.

This fix is introduced because in kwin_x11 (KDE project), X server can
exit on logout. kwin_x11 should handle disconnection from X server.
But the indefinite loop prevents kwin_x11 to process disconnection
event and therefore kwin_x11 cannot quit properly.

5082b84b38 QMetaObjectPrivate: Add firstMethod
QMetaObject::indexfOfMethod returns the method corresponding to a
specific signature. In QML, we however only want any of the methods with
a given name (and do overload resolution at a later point).
For this usecase this patch introduces the internal
QMetaObject::firstMethod function.

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.

81e893fb2d QHash: support std::hash as hashing function
In addition (and as a fallback) from requiring qHash, add support
for std::hash specializations. This catches two birds with one stone:

1) users of Qt can simply specialize std::hash for their datatypes,
and use them in both QHash and stdlib unordered associative containers;

2) we get QHash support for any (stdlib) datatype that is hashable
without having to overload qHash for them.

[ChangeLog][QtCore][QHash] QHash, QMultiHash and QSet now support
for key types anything that can be hashed via std::hash, instead of
always requiring a qHash() overload.

5dab710b90 Seedless qHash catch-all: make it SFINAE-friendly
To support qHash overloads without a seed we have a qHash(T, size_t)
catch-all that calls qHash(T) and XORs the seed. The problem is
that this catch-all is not SFINAE friendly. For a type Foo which
does not have any qHash overload, we can't ask if qHash(Foo, size_t)
is callable because it would instantiate the catch-all and fail
to compile.

Add a suitable trait and enable_if.

d982fdfca4 QHeaderView: allow un-sorting of models
If one clicks on a QHeaderView's section, the header view will
sort the view by the respective column/row. By clicking multiple
times, one is able to toggle the sorting between ascending
and descending. Something that is NOT possible to do however is to
un-sort the view -- that is, to restore the model's original
sorting. This must be done via code, by asking the header or the
view to sort by section -1.

This commit adds new property to QHeaderView to make it possible
to unsort models. Basically, the sort indicator becomes a tri-state:
sort ascending, sort descending, unsort (sort by column -1).

[ChangeLog][QtWidgets][QHeaderView] Added the sortIndicatorClearable
property. Setting this property allows the user to clear the sort
indicator on a section, resetting the model to its default ordering.

0440614af0 Replace discouraged Q_MOVABLE_TYPE by Q_RELOCATABLE_TYPE
Q_MOVABLE_TYPE was conceived before C++ had move semantics. Now, with
move semantics, its name is misleading. Q_RELOCATABLE_TYPE was
introduced as a synonym to Q_MOVABLE_TYPE. Usage of Q_MOVABLE_TYPE
is discouraged now. This patch replaces all usages of Q_MOVABLE_TYPE
by Q_RELOCATABLE_TYPE in QtBase. As the two are synonymous, this
patch should have no impact on users.
