8afe4faf29 QLineEdit: ignore key release events
Amends 55fe46fd58. Before that change,
key release events were ignored as the QLineEdit::event reimplementation
continued to call QWidget::event, and as QLineEdit didn't override
keyReleaseEvent, the default implementation in QWidget got called to
ignore the event.

Restore that behavior by explicitly calling the QWidget implementation
after updating QLineEdit-specific states, and add a test case.

855c448469 QPromise: Propagate cancellation through failure handlers
Previously, failure handlers did not propagate cancellation. This would
lead to crashes when a QPromise was cancelled without having generated
any result. Subsequent continuations would be invoked and try to access
the result (which was nonexistent) and then crash.
This patch propagates cancellation through failure handlers to prevent
subsequent continuations from being called in the first place.

96e1381a0a QBindable: Fix out-of-bound access in non-bindable property support code
QObjectPrivate::getPropertyAdaptorSlotObject called
connectionsForSignal.
Calling this function is only safe after it has been ensured beforehand that the vector has size > signalIndex. As getPropertyAdaptorSlotObject
is not supposed to modify the vector, it does not resize the vector and it could consequently end up with an out-of-bounds read.

To avoid that issue, we instead first check if the vector can
potentially contain an entry for the signal. If not, we simply return
nullptr, and avoid the call to connectionsForSignal.

The issue and its fix can be verified by running the modified
tst_qproperty test with ASAN enabled. The test is modified in the
following way:
- We first create a signal connection to a dummy slot. Otherwise,
  connections.loadRelaxed() would return a nullptr, and the problematic
  code would never be reached.
- We add enough signals to ensure that the fooChanged signal will
  actually be out of reach (which means >= 8 signals, as the initial
  capacity of the vector is 8)
Running the test without ASAN will most likely not result in a failure,
as then the out-of-bounds read will simply read garbage, and the most
likely result is that the cast below will fail.

7779400ba6 Moc: fix generated code for nested enum class corner case
Fixes an issue with generated code where the name of an enclosing
namespace is identical to an enum class type, when Q_ENUM_NS is used.

Consider:
namespace a {
    Q_NAMESPACE
    namespace b {
        enum class b { Key, Key2 };
        Q_ENUM_NS(b);
    }
}

moc generated code such as:
Q_CONSTINIT const QMetaObject a:🅱️:staticMetaObject = { {
    ...
    qt_incomplete_metaTypeArray<qt_meta_stringdata_CLASSaSCOPEbENDCLASS_t,
        // enum 'TestEnum'
        QtPrivate::TypeAndForceComplete<b::b, std::true_type>,
        // Q_OBJECT / Q_GADGET
        QtPrivate::TypeAndForceComplete<void, std::true_type>
    >,
    nullptr
} };

which confused the compiler:
error: ‘b’ is not a member of ‘a:🅱️:b
   83 |         QtPrivate::TypeAndForceComplete<b::b, std::true_type>,

f4dca7c512 Consult QIcon::fallbackThemeName() even for themes with explicit parents
We would previously only use the fallback theme for themes that did
not exist, or for themes that did not declare any parent theme.

We now unconditionally use the fallback theme, even for themes that
declare their own parent themes, so that a QIcon::fromTheme("foo")
that doesn't exist in the current theme, nor any of its parents,
nor in "hicolor", will still be looked up in the fallback theme.

The reason this seemed to work in the existing tests was because
our test themes inherit system themes such as crystalsvg and gnome,
and we didn't provide a hicolor theme. Any of these themes missing
would lead us into the code path where we use the fallback theme
for a missing theme, masking that fact that we had not added the
fallback theme to the list of fallbacks for the theme that had
explicit parents declared.

The logic has been moved out of the theme parsing and into an
accessor in QIconTheme, so that we're not caching the fallback
theme lookup.

[ChangeLog][QtGui][QIcon] QIcon::fallbackThemeName() will now be
used as fallback even for themes that declare a parent theme.

8393922e70 QComboBox: scroll the popup to the top before positioning it
If the style changes while a popup is open (or about to close),
the popup will change style as well before it's hidden. And
this can result in the popup window briefly ending up smaller
than what it needs to be, in order to fit all the menu items.
In that case, it will show 'up' and 'down' widgets in the
menu that auto scrolls it when hovered. And all this can
happen for a split second while the menu is about to close
(as a result of the user clicking on a menu item).

A bug happens because of this if you click on the last menu
item in the list, and this causes the style to change. In
that case, the 'down' widget will end up directly underneath
the mouse for a split second, which will trigger an auto-scroll
timer to start. This timer will trigger a bit later, after
the popup has been hidden, and scroll the list view a bit down.
The result is that the next time you open the popup, it ends up
at the wrong place on the screen in a failed attempt to center
the current index on top of the combobox.

This patch will make sure that we always scroll the list view
to the top before we start calculating where the popup should
be placed on the screen. Otherwise the geometry ends up wrong
since the popup will anyway be resized (if possible) to fit
all the menu items before it's shown and should therefore not
take scrolling into account.

af8f9a2a6e QStringBuilder: allow to be used with 'auto' keyword
The idea is to store a concatenable in a QStringBuilder object by value
or by reference, depending on how it was originally passed into the
concatenation operator. So if it was passed by r-value, we treat it as
a temporary object and hold it by value (and use move-semantic if
available), otherwise we hold it by reference (as before).

To achieve this we first change concatenation operators '%' and '+'
to take their arguments by universal reference. Next we instantiate
QStringBuilder object with deduced types of the arguments, which will
be a "value type" or a "reference type" according to "universal
reference deduction rules".

Further we use perfect forwarding to pass arguments to QStringBuilder's
constructor. Thus arguments, initially passed by r-value reference
and which are move-constructible, will be "moved" to corresponding
QStringBuilder member variables.

So, to summarize:
1. Arguments passed by l-value reference - stored in QStringBuilder
   object by reference (as before).
2. Temporary objects passed by r-value reference - stored in
   QStringBuilder object by value. If a type is move-constructible
   (QSting, QByteArray, etc), the object will be "moved" accordingly.

Special thanks to Giuseppe D'Angelo for the tests.

1f22fc995a Fix segfault when using qfuture continuations with move only types
When using move-only types, continuations args are set using takeResult
function, which has the side effect of invalidating the QFutureInterface
associated with the promise/futures by:

1. setting isValid to false
2. setting the state to NoState

And when the promise is destroyed, it tries to run the continuations if
`finished()` is not called, which is done by checking the Finished bit
in the state. But since the continuation has been run before, and the
state has been set to NoState it tries to run the continuation again
causing a segfault. Multiple solutions come in mind:

1. don't run the continuation if the state is NoState, but this would
   break the case when an empty promise is destroyed
2. check inside the continuation if it has been run before, and if so
   don't run it again, but this seems hacky since we don't want the
   continuation to be run twice, and it should break if it did.
3. when invalidating the promise leave the state as is, and change
   isValid only to false, which changes the current behavior, but is
   still compatible with the documentation which states only that
   isValid will return false if takeResult is called

I chose option 3

I also extended some tests to test for move only types, and added a test
that continuations run when a promise is finished. This simple case
would segfault before with move only types.

78cdd9a64d QPixmapCache: deprecate replace()
The replace() implementation overwrites the passed Key key with a new
version, const_cast'ing away the const from the key passed by
reference-to-const. This is UB if the Key was originally declared
const.

Deprecate the function.

Also inline the const_cast, so compilers can readily detect the UB
even if users don't enable deprecation warnings. Due to the severity
of the issue (UB), immediate deprecation is warranted. There appear to
be no in-tree user of the API outside of tst_qpixmapcache.cpp.

[ChangeLog][Deprecation Notice][QtGui][QPixmapCache] The `replace(key,
pixmap)` function has been deprecated, because passing a `const Key`
to it results in undefined behavior. Use `remove(key, pixmap)`
followed by `key = insert(pixmap)` instead.

c4635c0d58 QStyleSheetStyle: Default to foreground for unset brushes only
If a foreground style has been defined in the style sheet,
QStyleSheetStyle populates its brushes for the color roles ButtonText,
WindowText, Text, and the widget's foregroundRole with the foreground
brush. PlaceholderText is set to the same brush with a modified color.

That sets their resolve bits in QStyleSheeetStyle's palette and
prevents these color roles from being inherited by the widget's
palette - in contrast to all other brushes.

This patch makes the brushes mentioned default to the widget's palette
if they are set there. It adds a test in tst_QStyleSheetStyle.

78acaf4fb6 Fix sending deferred delete events when posted before outermost loop
QDeferredDeleteEvent has the loopLevel field, which is a sum of
scope and loop levels found at posting. In sendPostedEvents however,
it is impossible to only use this information to find delete events
posted before the outermost loop (which should be handled by any loop)
based solely on this information, as the scope level essentialy removes
the information on loop level.

Break the loopLevel in two, storing both loop and scope levels in
QDeferredDeleteEvent, so that we can check whether an event was posted
before the outermost event loop (for which we need to compare only the
loop level).

QDeferredDeleteEvent was also made private as it should - it is an
implementation detail that wasn't hidden properly.

We observe failures in CI on QNX because the measured timeout is ~995ms
rather than the expected 1000ms. Start the timer before the thread
starts to guarantee that at least as much time elapses as the thread
waits before writing the second byte to the pipe.

Otherwise, the thread might be sleeping already when the timer starts,
and then we can't rely on any measurements.

0e96dd3464 tst_QPixmapCache: QVERIFY a failed replace()
Between the find() == 0 obfuscation (since fixed) and this unchecked
replace(), it took me way too much time to figure out what was going
on: the key passed has been invalidated by the setCacheLimit(0).

Now that we QVERIFY that the replace() _fails_, it's much easier to
backtrack and figure out why it does so and why, consequently, the
following find() is also expected to fail.

As a drive-by, reorder two lines so the grouping becomes clearer
(blocks now both headed by setCacheLimit()).

05e3880130 QString: add STL-style assign() [3/4]: (it,it) overload for char32_t
This no longer is range-length preserving now, so adapt the
documentation.

For the non-contiguous iterator case, it's actually ok to always
resize(0) and then append(), because, unlike for QList and QVLA, the
resize(0) doesn't actually iterate the container to destroy
elements. It just sets some members and conveniently detach()es for
us.

The char8_t case is even more complicated, since we can, atm, not
include qstringconverter.h into qstring.h, yet qstringconverter is
required for stateful UTF-8 decoding in the input_iterator case. So
that's postponed to yet another patch, and maybe won't make it into
6.6. But I feel it's important to have at least one
non-length-preserving version of assign(it, it) in before release lest
users come to rely on this documented (and de-facto) feature of the
the step-2 assign().
