Previously if qtbase was built with feature A set to ON, then building
qtsvg, then rebuilding qtbase with feature A set to OFF, trying to
build qtsvg would fail with an error message at configure time saying
that the feature value has changed.
This check was added quite early in the Qt CMake port, presumably to
catch accidental reconfigures that might cause long rebuilds.
This has dubious benefit though. We constantly had people telling us
they get the error without knowing what to do. The usual advice was to
remove CMakeCache.txt and reconfigure.
Instead of forcing people to suffer this dance, relax the constraint
by issuing a warning instead of an error, and make it more clear why
a rebuild might happen (a changed feature value might change
the generated module C++ header file which in turn might be included
by various project sources).

...by removing the entire adjustedFormat() helper.
Qt Quick has never used this, which indicates it is not that
useful. Same goes for Qt Multimedia or Qt 3D. Ensuring depth and
stencil is requested is already solved by using
QSurfaceFormat::setDefaultFormat() or by adjusting the formats
everywhere as appropriate.
The helper function's usages are in the manual tests that use it as a
shortcut, and in the GL backend itself. Remove it and leave it up the
client to set the depth or stencil buffer size, typically in the
global default surface format. (which in fact many of the mentioned
manual tests already did, so some of calls to
window->setFormat(adjustedFormat()) were completely unnecessary)
By not having the built-in magic that tries to always force depth and
stencil, we avoid problems that arise then the helper cannot be easily
invoked (thinking of widgets and backingstores), and so one ends up
with unexpected stencil (or depth) in the context (where the GL
backend auto-adjusts), but not in the window (which is not under
QRhi's control).
It was in practice possible to trigger EGL_BAD_MATCH failures with the
new rhi-based widget composition on EGL-based systems. For example, if
an application with a QOpenGLWidget did not set both depth and stencil
(but only one, or none), it ended up failing due to the context -
surface EGLConfig mismatches. On other platforms this matters less due
to less strict config/pixelformat management.

Problem description:
--------------------
Assume we have two properties, P1 and P2. Assume further that we assign
a binding to P2, so that it depends on P1. Let the binding additionally
capture some (non-QProperty) boolean, and only create the dependency to
P1 if the boolean is true.
The state afterwards is
P1:[p1vaue|firstObserver]
|
|
v
---[p2binding]
/
P2:[p2value|binding]
If the boolean is set to false, and P1 changes its value, we still
correctly re-evaluate the binding and update P2's value. However, during
binding evaluation we will notice that there is no further dependency
from P2 on P1, and remove its observer.
The state afterwards is
P1:[p1vaue|firstObserver=nullptr]
---[p2binding]
/
P2:[p2value|binding]
Then, during the notify phase, we traverse the observer's again,
starting from P1's firstObserver. Given that it is nullptr now, we never
reach P2's binding, and thus won't send a notification from it.
Fix:
----
We store a list of all visited binding-observers (in a QVarLengthArray,
to avoid allocations as long as possible). After the binding evaluation
phase, we then use that list to send notifications from every binding
that we visited. As we already have a list of all bindings, we no longer
need to recurse on binding-observes during the notification process;
instead, we only need to deal with static callbacks and ChangeHandlers.
The pre-existing notification logic is still kept for the grouped update
case, where we already have a list of all delayed properties, and should
therefore not encounter the same issue. Unifying its codepath with the
existing logic is left as an exercise for a later patch.

Until Qt 5.15, PlaceholderText color was automatically derived from the
Text color, dimmed by 50% (set alpha to 128, assuming the text color
is fully opaque).
This method has been adapted in the static qt_fusionPalette() method.
No other static method to populate palettes defines a PlaceholderText
color. As a consequence, the Text color is used to render placeholder
text characters.
This patch adds a static method, that sets missing PlaceholderText
colors by deriving them from the corresponding Text color.
It takes a dim factor by which the opacity is reduced versus the
corresponding Text color.

When combining Qt Quick and QPainter targeting the same GL window,
calling QQuickWindow::beginExternalCommands() is not currently
sufficient to ensure problem-free operation, it also needs a
QQOpenGLUtils::resetOpenGLState() afterwards to get rid of the buffer
bindings. (which is important when using legacy code with client-side

The problem is reported in combination with the new 6.4 way of
handling texture-based widgets, but this looks like something that has
always been missing:
Setting WA_TranslucentBackground changes the QWidgetWindow's format,
and this is done upon calling setAttribute(). That's good for most
cases, but the changes to the QWindow's format are lost when the
window is destroyed and then the widget gets another window
later. This is not that common, but can happen.
For example, if a top-level widget is parented under something else,
and then later it is parented to null again, so that it is toplevel
once again, background transparency can be lost because nothing
re-evaluates the WA_TranslucentBackground flag after the initial
setAttribute(), and so the widget's second QWidgetWindow is not set up
accordingly (because this new QWindow may not have alpha specified in
the QSurfaceFormat which may or may not be a problem, depending on the
platform / windowing system)
The simple solution is to evaluate the attribute not just when setting
it, but also when a new QWidgetWindow is created for the widget.

QRegularExpression::match (and globalMatch) is currently overloaded
for QString and QStringView. This creates a subtle API asymmetry:
QRegularExpression re;
auto m1 = re.match(getQString()); // OK
auto m2 = re.match(getStdU16String()); // Dangling
This goes against our decision that every time that there's a possible
lifetime issue at play, it should be "evident". Solving the lifetime
issue here is possible, but tricky -- since QRegularExpression
is out-of-line, one needs a type-erased container for the input
string (basically, std::any) to keep it alive and so on.
Instead I went for the simpler solution: deprecate match(QStringView)
and introduce matchView(QStringView) (same for globalMatch). This
makes it clear that the call is matching over a view and therefore
users are supposed to keep the source object alive.
Drive-by, remove the documentation that says that the QString
overloads might not keep the string alive: they do and forever will.

and globalMatchView() functions that operate on string views.

However, we know if we want to be dark or light, and can construct a

In the course of doing that, refactor and clean up the code somewhat to
