Testcase appearsAndSort failed when running the complete testcase but
not as single test. More irritating was the fact that the error was in
QAbstractItemModelTester::headerDataChanged() but the affected test did
not change any header nor does it use the blamed model...
The reason for this is, that QAbstractProxyModel emits a queued
headerDataChanged signal when the header item count changes and
therefore only evaluated when the event loop is run.
Fix it by calling processEvents() after the rowCount change in
filterColumns().

a611a9f537 (in Qt 5) added support for
mixed-type comparisons through QCOMPARE. That commit added a new
overload for qCompare taking two types, T1 and T2; but it also left the
same-type qCompare(T, T) overload around, guarded by a Qt 6 version
check.
The mixed-type version is however not a generalization of the same-type
one, because it won't work if one of the arguments doesn't participate
in FTAD. Case in point: braced-init-lists. In Qt 5 this worked:
QCOMPARE(some_container, {42});
but in Qt 6 it does not work any more. The mixed-type overload fails
deduction (can't deduce T2); in Qt 5 the same-type overload deduced
T=SomeContainer, and {42} was used to select a constructor for
SomeContainer.
--
There's a partial, straightforward workaround for this: default T2 to
T1 in the mized-type overload. In that case T2 has a "fallback" if it
cannot be deduced. This is partial because of course doesn't address
the case in which T1 cannot be deduced, but I don't think that is
common at all.
QList is special here, because it has qCompare overloads that makes it
comparable with arrays, initializer lists and more. I don't like that
very much -- we should probably have a qCompare(input_range,
input_range) overload, but that's an exercise for C++20.

`QVariant::convert` may lead to crash or produce garbage data when
attempting to convert a gadget between a pointer type and a value type,
for example from a variant holding a QLocale gadget to a QLocale*
pointer and vice versa. Similarly, `QVariant::view` may crash under the
same conditions.
The reason is that conversion is implemented through copy construction
assuming that both source and target types are either both pointers or
both values. If converting from pointer to value type, the result is
crash during destruction of the QVariant. If converting from value to
pointer type, the result is a QVariant holding a pointer to garbage
data (and possibly crash if pointer is dereferenced).
Similarly, if attempting to convert a pointer to a QObject derived type
to its value type, the system crashes, with a slightly different failure
mode. During `QVariant::convert`, a temporary `QVariant` of the target
type is created. Since objects that can not be copy constructed are
invalid for `QVariant`, the temporary is left empty without constructing
the target value. Then, when attempting to convert from a pointer type
to a value type, the temporary's destructor is incorrectly called on the
owned object. Since the owned object is never constructed, this leads to
a crash.
The proposed fix is to return false from `QMetaType::view`,
`QMetaType::canView`, `QMetaType::convert`, and `QMetaType::canConvert`
if the target type is of different 'pointedness' than the source type.
After this fix, converting and viewing gadgets and QObjects behaves the
same way as primitive types and core types, which already returned false
when converting between value type and pointer type.

shouldn't between vfork() and execve().
Most C libraries (all that I've investigated) unblock SIGABRT on
abort(), so this doesn't affect them. Likewise, on most OSes, crashes
ignore the signal block and terminate the application -- Darwin appears

which calls fastScanName()
- fastScanName() iterates over the text buffer scanning for the
attribute name (e.g. "xml:lang"), until it finds ':'
- Consider a Value val, fastScanName() is called on it, it would set
val.prefix to a number > val.len, then it would hit the 4096 condition
and return (returned 0, now it returns the equivalent of
std::null_opt), which means that val.len doesn't get modified, making

with the same amount of newly added rows/sections.
That leads to the initial amount of sections being 2x the number of
rows added in the first go. In other words, the table view will display
at least one row more than the underlying table model has.
This patch adds an OR condition to the early return check at the
beginning of QHeaderView::sectionsInserted(). The method returns early
if the number of sections equals the number of respective sections

33c88f86b5 added some logic to QAPM in
order to have it automatically emit headerDataChanged when rows/columns
were added or removed in the model. This was done as a stopgap measure
to prevent QAPM from asking for illegal indices in order to implement
automatic remapping of the section headings (since there's no
mapSectionToSource).
The commit seems to have introduced a regression in QHeaderView, which
isn't prepared to receive headerDataChanged while a row/column count
change is in progress. When receiving headerDataChanged, QHeaderView
will try to read the row/column count and will store it internally.
When it will then receive the signals for insertion/removal of
rows/columns, it will interpret it as a modification of the previously
stored value -- even if the value it stored was already correct.
Fix this by avoiding to have two signals in flight at the same time;
emit headerDataChanged as a queued invocation.

When setFuture() was handed an element of m_futures, it would hold the
reference to past the clear(), which invalidates said reference.
Fix by taking the future by value instead of by cref.
While append() is not affected, as QList::append() already guards
against aliasing, do the same change there, both for consistency as
well as to optimize the common case of passing rvalues. It also means
we can use the rvalue overload of QList::append(), skipping the alias
analysis in the lvalue QList::append().
[ChangeLog][QtConcurrent][QFutureSynchronizer] Fixed a crash in
setFuture() if the argument was already a member of
QFutureSynchronizer::futures().

QWidgetPrivate::focusObject() always returns nullptr. That has lead to
mismatches between QGuiApplication::focusObject() and
QApplication::focusWidget(), when a widget got focus by the window
system (e.g. mouse click).
This patch implements QWidgetPrivate::focusObject.
It returns the current widget, if it doesn't have a focus proxy.
If it has a focus proxy, it resolves the proxy chain and returns the
deepest focus proxy.
(Note: It does not return QWidget::focusWidget(), because the focus
widget might not yet have been set, when the method is called).
