This fixes a crash while parsing an XML file with garbage data, the file
starts with '<' then garbage data:
- The loop in the parse() keeps iterating until it hits "case 262:",
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
it smaller than val.prefix
- The code would try constructing an XmlStringRef with negative length,
which would hit an assert in one of QStringView's constructors
Add an assert to the XmlStringRef constructor.
Add unittest based on the file from the bug report.
Later on I will replace FastScanNameResult with std::optional<qsizetype>
(std::optional is C++17, which isn't required by Qt 5.15, and we want to
backport this fix).
Credit to OSS-Fuzz.

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.

It looks like AAssetDir_getNextFileName is not enough.
Directories that contain only other directories (no files)
were not listed.
On the other hand, AAssetManager_openDir() will always return a
pointer to initialized object (even if the specified directory does not
exists), so we can't just leave only it here.
Using FolderIterator as a last resort. This approach should not be too
time consuming.
As part of this fix, add some unit tests to cover/ensure assets
listing/iterating works as expected.

We so far only handled them if they came at the very start of the method
declaration.
This patch ensures that we also handle them after the meta-method tag
(but before the actual type).
Unifying parseFunction and parseMaybeFunction to avoid the need to
munally keep them in sync is left for another day.

These APIs started out as private APIs in qnumeric_p.h, but have since
been made pseudo-public in qnumeric.h. The qnumeric_p.h versions just
forward to the qnumeric.h ones, so just use the latter.
This is in preparation of removing the {add,sub,mul}_overflow
versions, which, despite being defined in the unnamed namespace, don't
sport the q prefix, so potentially clash with global symbols.
The change is a simple textual search and replace, manually excluding
qnumeric_p.h.
Picking to 6.5 to avoid cherry-pick conflicts going forward.

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.

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.

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.

QMenu's causedStack maintains a list of menus on the way to the menu,
and might contain nullptr if one of the entries was a tear-off menu
that got closed (and thus destroyed, due to DeleteOnClose).
If the entry we get from the stack is nullptr, fall back to the passed-
in parent widget pointer, and test for nullptr before accessing.
Add a test case that crashes without the fix.

QPixmapCache maintains a mapping from QString to QPixmapCache::Key, in
the form of the cacheKeys QHash, but QPixmapCache::clear() didn't
touch it, leading to the string data (as well as the Keys) being
retained after any possible use. This can lead to memory slowly being
eaten up, as reported in QTBUG-112200, and prevents a periodic calling
of QPixmapCache::clear() from being a work-around for the issue in the
bug report.
Fix by clearing cacheKeys in QPixmapCache::clear().
This is designed as a low-risk enabler of a work-around, not a fix for
the issue. The work-around enabled by this is periodic calling of
QPixmapCache::clear().

If an application sets the current index and resizes the tab widget
before showing it, then the scroll offset might be calculated based on
an old size. Since after ca15f650a1a914bb9a41131109c46c4e52c5ebb1,
resizing explicitly avoids scrolling, this could result in tabs ending
up scrolled outside of the tab bar when showing the tab widget.
Fix that by explicitly making the current tab visible in the tab bar's
showEvent handler, which recalculates the scroll offset based on the
actual size.
This is only reproducible with a tab widget, which lays out the tab bar
for each change and resets the tab bar's layoutDirty flag. Add a test
case there.

Otherwise individual sockets will still load system certificates when
a chain doesn't match against the configured CA certificates.
That's not intended behavior, since specifically setting the CA
certificates means you don't want the system certificates to be used.

This is potentially a breaking change because now, if you ever add a
CA to the default config, it will disable loading system certificates
on demand for all sockets. And the only way to re-enable it is to
create a null-QSslConfiguration and set it as the new default.

When forwarding a signal, associate this signal with its
enclosing metaobject instead of its sender's metaobject.
Those two may be different if the signal is declared in
a base class.
Add a regression test into tst_qdbusconnection.

Check that we can navigate to rows and columns, and that we get the
right text back for cells.
We see API failures in CI on some macOS nodes, accompanies by the debug
message:
AXUIElementCopyAttributeValue( "AXTitle" ) returned error =
AXError(value=-25201, name=kAXErrorIllegalArgument,
description="An illegal argument was passed to the function.")
On hosts where the test fails, we always see this warning, so extend the
test helper with an errorOccurred boolean that we can test and if set
skip the test.

Not entirely clear why, but when building the certificate chain for a
peer the system certificate store is searched for root certificates.
General expectation is that after calling
`sslConfiguration.setCaCertificates()` the system certificates will
not be taken into consideration.
To work around this behavior, we do a manual check that the root of the
chain is part of the configured CA certificates.

In QAccessible's widget implementations, trees are treated as tables,
with a rowCount implementation that is based on the view's current
item content. That item content is the view's content, not the model's,
and it changes when tree branches are expanded.
The Cocoa bridge for accessibility allocates arrays of row data
structures based on the rowCount implementation. Those data structures
need to be invalidated and recreated when the view's content changes.
To do that, emit an accessibility event for a model reset when laying
out items changes the size of the view's item array. We don't know what
changed during that layout process to makes this any more granular.
Amends 11ae55e918082e8fdfc0c88c21049e877cc47b5b, but the problem
with the data structure being stale and incorrect would have been there
before that chain of changes optimizing. It didn't trigger an assert,
but probably resulted in incorrect data being reported.
To make trees testable, we need to actually expose them as AXOutline
to the macOS accessibility framework. Until now, they have been treated
like plain QWidget, e.g. AXGroup. This made them in practice in-
accessible. With this change, VoiceOver works much better (although not
perfeclty yet).
Also remove an assert that could be triggered by an accessibility
client asking for a cell for an invalid index (which can be reproduced
by navigating around in a tree, following debug warnings from
QAccessibleTree::indexFromLogical: invalid index).

This is a back-port to 6.5 of both the special-case handling of
Cyrillic's exponent separator [0] and the fix to that, that prompted
this cherry-pick. Both changes were made after significant
restructuring of relevant code to cope with multi-character exponent
separators, which is not backported to 6.5.
[0] commit cb54da236662563bfdc2f58a01320c3bd360cbff

Avoid capturing the same property multiple times in a binding by
storing them in the BindingEvaluationState. We store them in a
QVarLengthArray array, as the number of properties involved in a binding
is expected to be rather low, so a linear scan is fine.
Avoiding double capture is a good idea in general, as we would otherwise
needlessly reevaluate bindings multiple times, and also needlessly
allocate memory for further observers, instead of using a binding's
inline observer array.
Even more importantantly, our notification code makes assumptions that
notify will visit bindings only exactly once. Not upholding that
invariant leads to memory corruption and subsequent crashes, as
observers allocated by the binding would get freed, even though we would
still access them later.

It adds nothing new to what the trivial and license wizard examples
show, other than a bunch of somewhat messy and outdated code to generate
C++ code files based on the input.
The example is referenced in a few parts of the documentation, but there
are equivalent snippets in the trivial and license wizard examples, so
point at those instead, and add some relevant API usage where needed.

We already know the Symbol while parsing, passing a reference to it to
error() makes it simpler to construct the error message.
This fixes an issue where reporting an error about "NONSENSE" in e.g.:
Q_PROPERTY(Foo* foo NONSENSE foo)
would be off-by-one and the error message would say:
path/to/file.h:11:1: error: Parse error at "foo"
instead of 'at "NONSENSE"', which is where the parser actually found an
unexpected attribute.

The tutorial is building an elaborate UI around a QMap. It doesn't use
structured data, and it doesn't use model/view (which the dedicated
addressbook example in itemviews does).
It's not a good way of building an application, and the individual APIs
for creating layouts, dialogs, or import/export are explained well
enough in other examples.

STL algorithms, in general, don't specify how often the function
objects passed to them are copied during the run of the
algorithm.
While generate_n is above any reasonable suspicion of copying the
function object after the first invocation, passing a mutable lambda
containing the counter is still an anti-pattern we don't want people
to copy.
Fix in the usual way, by keeping the counter external to the lambda.
As a drive-by, replace post- with pre-increment.
