The QVariant(QMetaType) constructor is a major anti-pattern: unlike
*every* other QVariant's constructor, it doesn't build a QVariant
holding the QMetaType object, but a QVariant of the specified type.
Introduce a named constructor for this use case instead.
In principle, this should lead to a deprecation of the QMetaType
constructor... except that it's used everywhere, so I can't do it at
this time.
Drive-by, improve the documentation of the QVariant(QMetaType)
constructor (since it's basically c&p for the new fromMetaType
function).
[ChangeLog][QtCore][QVariant] Added the QVariant::fromMetaType named
constructor, that builds a QVariant of a given QMetaType.

That we have two macros to declare a C++ type to represent a Java class
is confusing. The TYPE macro as of now allows us to declare array types,
but with QJniArray we won't need that anymore, and can just use Class[]
as the type instead. Changing that will be a follow-up commit; for now,

A QMimeTypePrivate used to belong to a single provider, which would
provide the complete data for it.
But since the redesign in commit 7a5644d648, each provider
represents is a single mime directory, and the merging happens at the
QMimeDatabase level. So we need a QMimeType[Private] to be just a name
(a "request" for information about this mimetype) and the information
for that mimetype is retrieved on demand by querying the providers
and either stopping at the first one (e.g. for icons) or merging
the data from all of them (e.g. for glob patterns).
The XML provider was using QMimeTypePrivate as data storage,
give it its own struct QMimeTypeXMLData for that purpose instead.

There were two problems:
- On platforms where QFLOAT16_IS_NATIVE == true, a qHash(qfloat16{})
call has become ambiguous between the three FP qHash() overloads
(float, double, long double), where it was unambiguously calling the
float one in Qt 6.4. This SiC was caused by the replacement of
operator float() by operator __fp16() in
99c7f0419e, which is in Qt 6.5.
- On platforms where QFLOAT16_IS_NATIVE == false, qHash(qfloat16{})
would produce a different value from qHash(float{}), and therefore
Qt 6.4, when the seed was != 0, because the former would go via the
one-arg-to-two-arg qHash adapter while the latter one would
not. Since participating functions are inline, this causes old and
new code to produce different hash values for the same qfloat16,
leading to a BiC possibly corrupting QHash etc.
Fix both by adding an explicit qHash(qfloat16). This function is
inline, so it doesn't add a new symbol to 6.5.x.
[ChangeLog][QtCore] Fixed qHash(qfloat16) which was broken from 6.5.0
to 6.5.3, inclusive. If you compiled against one of the affected Qt

0b421fa58b9a73d657bf17834788fd1175c4767e ensured a correct focus chain,
when buttons in a QDialogButtonBox were hidden.
The implementation did not check, if a hidden button was added via
setStandardButtons(). In consequence, it was removed from the
standardButtonHash and never added again.
QDialogButtonBox::button() returned nullptr for a standard button,
once it had been hidden. That introduced a regression.
This follow-up patch makes sure, a standard button is not removed
from standardButtonHash, when hidden. By no longer removing it from
standardButtonHash, it makes showQDialogButtonBox::button() always
return the pointer to the standard button, even if it is hidden.
The function handleButtonDestroyed() used the argument
QDialogButtonBoxPrivate::RemoveRule::KeepConnections, in order to leave
signal/slot connections untouched. It expected the the destroyed button
to be removed from standardButtonHash. In order to retain that
functionality, the enum class RemoveRule is renamed to RemoveReason,
and one value was added. QDialogButtonBoxPrivate now handles all
necessary cases of removing a button:
ManualRemove (previously Disconnect):
- remove button from roles
- remove button from standardButtonHash
- disconnect all signals
LeaveEvent (previously KeepConnections):
- remove button from roles
- do not remove button form standardButtonHash
- do not disconnect signals
Destroyed (new):
- remove button from roles
- remove button from standardButtonHash
- do not disconnect signals (QObject will do that)
An autotest is added to tst_QDialogButtonBox.

QWidget::setVisible is virtual, and called via hide() by both the

when getting destroyed will at most execute the QDialog override.
Subclassing QDialog and overriding setVisible() to update the state
of the native platform dialog will not work, unless we explicitly
call hide() in the respective subclass's destructor.
Since e0bb9e81ab, QDialogPrivate::setVisible is
also virtual, and gets called by QDialog::setVisible. So the clean
solution is to move the implementation of the native dialog status
update into an override of QDialogPrivate::setVisible.
Add test that verifies that the transient parent of the dialog
becomes inactive when the (native) dialog shows (and skip if that
fails), and then becomes active again when the (native) dialog is
closed through the destructor of the Q*Dialog class. The test of

Instead of adding it after the block size was calculated. This makes no
difference for non-growing (exact) blocks. For growing blocks, this
means we take that extra element into account before rounding to the
next power of two, instead of after. That results in a change of the
thresholds of when a block grows and also what capacity it will
contain.
For example, for a QString growing to 22-25 elements:
Request | Previously | Now |
elements | bytes | malloc()ed | capacity() | malloc()ed | capacity() |
22 | 44 | 66 | 24 | 64 | 23 |
23 | 46 | 66 | 24 | 64 | 23 |
24 | 48 | 66 | 24 | 128 | 55 |
25 | 50 | 130 | 56 | 128 | 55 |
To avoid wasting elementSize - 2 bytes in this footer, we only include
this footer if elementSize <= 2. Thus, for a QList<int> growing to 11-13
elements:
Request | Previously | Now |
elements | bytes | malloc()ed | capacity() | malloc()ed | capacity() |
11 | 44 | 66 | 12 | 64 | 12 |
12 | 48 | 66 | 12 | 128 | 28 |
13 | 52 | 130 | 28 | 128 | 28 |
In both cases, we now only allocate powers of two while growing, which
may be beneficial to some allocators.

The SizeShift was not taken into account when constructing QASV from
QL1SV. This is not an issue in normal Qt builds, because SizeShift == 0
there.
But in bootstrapped case (and in future Qt 7) SizeShift changes to 2,
and the bug becomes visible.
The added test-cases do not really reveal the issue, because we do
not run tests in bootstrapped builds, but at least they will help
to prevent the issues in Qt 7.

usually a short-lived, stack-allocated object, as in
QTextMarkdownImporter(&doc, QTMI::DialectGitHub).import(input);
So it's less clumsy internally to require the document be provided to
the constructor: that way a QTextCursor can be constructed immediately
too, as part of the importer object rather than separately on the heap.
This is private API, unused outside qtbase.

in this code path, instead of enabling it for QWidget. The latter

Docs and header comments have been updated to reflect that this
event is not widget specific. (This is an issue with other events

from a time when there was only QWidget, but nowadays apply to
e.g. QWindow as well. That's something for another fix though).

It's currently conditional on two features used in QNetworkInterface.
The fact that QNetworkInterface misses those two features is probably
correlated to the failures observed on QNX, but is not the cause, so
this code was actually wrong and was possibly disabling the execution of
similar content on other OSes.
Therefore, this commit removes them and changes the conditional to
exclude the OS that is failing (QNX).
I find this situation unacceptable. IPv6 support is mandatory for any
application after 2011-01-31, the date when IANA delegated its last IP
block, and definitely after 2019-11-25, when RIPE NCC ran completely

This involves reimplementing QWidgetPrivate::grabFramebuffer().
Widgets call this function whenever a texture-based widget is

This implies however that we rename QRhiWidget's own, lightweight
grab function, grab(), because it kind of shadows QWidget's grab().
Switch back to grabFramebuffer() which is what QQuickWidget and
QOpenGLWidget both use.
Supporting QWidget::grab() is particularly important when grabbing
an ancestor of the QRhiWidget, because that has no alternative.
Right now, due to not reimplementing the QWidgetPrivate function,
the place of the QRhiWidget is left empty.
In addition, grabFramebuffer() is now const. This is consistent
with QQuickWidget, but not with QOpenGLWidget and QOpenGLWindow.

This was missing for a while, and there is nothing fundamentally
missing for it to work.
With the more recent work around slot objects and invokeMethod in
general, it is a good time to add support for this.
In this patch, when connecting to a functor, it automatically deduces
the overload to call based on the arguments passed to invokeMethod.
Sharing code with QObject::connect could be done, but they have a
key difference that makes it harder:
With signal emissions we throw away trailing arguments that are not
used: i.e. `signal(int, int)` can be connected to `slot(int)` or
`slot()`. With invokeMethod that's not a thing. So we will need a way
to toggle that behavior during resolution.

The was introduced with the rewrite of QMetaObject::invokeMethod() in
commit 0f76e55bc4, because we have an
optimization for zero timers to avoid creating a temporary
QSingleShotTimer object. The old implementation did attempt to normalize
the target slot name, but did so because it looked metamethods up using
QMetaObject::indexOfMethod:
int idx = meta->indexOfMethod(sig.constData());
if (idx < 0) {
QByteArray norm =
QMetaObject::normalizedSignature(sig.constData());
idx = meta->indexOfMethod(norm.constData());
}
The new implementation does not use this method so it didn't need to
attempt to normalize.
I am fixing this only in QTimer and not in QMetaObject::invokeMethodImpl
(even though it is trivial to do so) because I don't believe spaces in a
pure string to invokeMethod were ever expected to work:
QMetaObject::invokeMethod(obj, "slotName ", Qt::QueuedConnection);
The Q_ARG and Q_RETURN_ARG (for code not recompiled) still does
normalization inside QMetaType::fromName().

When appending to an empty string or byte array, we optimize and
copy the internal pointer. But if the other string/byte array was
created with fromRawData this might be temporary data on the stack/heap
and might be de-allocated or overwritten before the string/byte array
is used or is forced to make a deep-copy. This would lead to incorrect
data being used.
This is easy to overlook if you plan to append multiple strings
together, potentially supplied through an argument. Upon appending a
second string it would make a full copy, but there might not be a
guarantee for that. So, it's hard for users to avoid this pitfall!

extremely high, too high for anyone to tackle in a short amount of

make progress on a global QT_NO_FOREACH default, so grab the nettle
and stick to our strategy:
Mark the whole of Qt with QT_NO_FOREACH, to prevent new uses from
creeping in, and whitelist the affected TUs by #undef'ing
QT_NO_FOREACH locally, at the top of each file. For TUs that are part
of a larger executable, this requires these files to be compiled
separately, so add them to NO_PCH_SOURCES (which implies
NO_UNITY_BUILD_SOURCES, too).

latter stores each new connection's name in m_connections
- An QTestEventLoop is entered, which triggers handleConnection(),
handleConnection() calls exitLoop() at the bottom (this is repeated

- server.unregisterObject() is called, iterating over m_connections

The method calls show() on a dock widget group window, when the window
flags have changed. When all of its contained, tabbed dock widgets are
programmatically hidden or docked on the main window, an empty group
window is shown.
This patch implements bool hasVisibleDockWidgets(). It returns true, if
at least one of the group window's dockwidget children is not hidden.
It replaces show() by setVisible(), passing the return value of
hasVisibleChildren().
It adapts tst_QDockWidget::floatingTabs() to test the fix.

The method reads the next element in a loop, as long as valid elements
exist. Within the loop, it returns
- false if the end of an element has been reached
- true if a new element has started
When the document end has been reached, the loop continues, until
readNext() returns Invalid. Then, PrematureEndOfDocumentError is launched.
This is wrong, because reading beyond the document end is caused by a
missing return condition in the loop.
=> Treat document end like element end and return false without
reading beyond it.

Commit 850d850c5a changed from
qMetaTypeId<QDBusArgument>() to QMetaType::fromType<QDBusArgument>() and
in Qt 6, fromType() does not register the type with the database. That
means the lines became runtime no-ops at that time or during the
QMetaType updates since 6.0. All they did was instantiate the C++ inline
variable.
The testing also detected we didn't register QList<QDBusVariant> as an
alias for the "av" signature. I'm not entirely sure you're allowed to
use this because QtDBus does not like re-registration of the built-in
types, and "av" is already assigned to QVariantList. This is no trouble

We've known for a long time that this is producing worse code with GCC
because of how we implemented in Q_ASSUME_IMPL(). So bite the bullet and
actually deprecate the macro, replacing all extant Q_ASSUME() with
Q_ASSERT().
The replacement is in C++23. Backporting the support onto Q_ASSUME_IMPL
was previously rejected by reviewers.
[ChangeLog][Deprecation Notice] The Q_ASSUME() macro is deprecated. This
macro has different side-effects depending on the compiler used (GCC
compared to Clang and MSVC), and there are certain conditions under
which GCC is known to produce worse code than if the macro was absent.

"Unnamed" constructors are important when emplacement is more

QAndroidPlatformInputContext::focusObjectStopComposing() sends an input
event for each character newly added by the Android virtual keyboard.
It then sends a second input event to notify that the cursor has
advanced to the position after the new character.
The implicit assumption is, that the receiver of the input event does
not change the text.
If e.g. QLineEdit::setText() is called in the QLineEdit::textEdited
slot, the text does change. If the change implies a cursor change,
QLineEdit notifies the platform input context about it.
However, by sending the second input event, QAndroidPlatformContent
returns the cursor back to the position after the last character added
by the virtual keyboard.
This patch joins the composed text and the cursor position into one
single input method event. A new cursor position, set by the receiver
of the input method event, is no longer overridden.

Take 2.
Re-land previously reverted commit, due to not handling resource names
that are not valid c++ identifiers. Now we sanitize the resource names
just like rcc does by replacing non-alphanumeric characters with
underscores.
Original commit message.
During the Qt 5 -> Qt 6 and qmake -> CMake porting time frame, it was
decided to keep resources in an object file (object library), rather
than putting them directly into a static library when doing a static
Qt build, so that the build system can take care of linking the
object file directly into the executable and thus not forcing
project developers to manually initialize resources with
the Q_INIT_RESOURCE() macro in project code.
This worked for most qmake and cmake projects, but it created
difficulties for other build systems, in the sense that these projects
would have to manually link to the resource object files, otherwise
they would get link time errors about undefined resource symbols,
assuming they kept the Q_INIT_RESOURCE() calls.
If the project code didn't contain Q_INIT_RESOURCE calls, the
situation would be even worse, the linker would not error out,
and the missing resources would only be discovered at runtime.
It's also an issue in CMake projects that try to link to the
library files directly instead of using the library target names,
which means the object files would not be automatically linked in.
Many projects try to do that because we don't yet offer a convenient
way to install libraries and reuse them in other projects (the SDK
case), so projects end up shipping only the libraries, without the
resource object files.
We can improve the situation by moving the resources back into their
associated static libraries, and only keeping a static initializer as
a separate object file / object library, which references the actual
resource initializer symbol, to ensure it does not get discarded
during linking.
This way, projects that link using targets get no behavior difference,
whereas projects linking to static libraries directly can still
successfully build as long as their sources have all the necessary
Q_INIT_RESOURCE calls.
To ensure the resource symbols do not get discarded, we use a few new
private macros. We declare the resource init symbols we want to keep as
extern symbols and then assign the symbol addresses to volatile
variables.
This prevents discarding the symbols with the compilers / linkers we
care about.
It comes at the cost of an additional static initializer per resource,
but we would get the same + a bigger performance hit if we just used
Q_INIT_RESOURCE twice (once in the object lib and once in project
code), which internally needs to traverse a linked list of all
resources to check if a resource was initialized or not.
For GHS / Integrity, we also need to use a GHS-specific pragma to keep
the symbols, which we currently use in qtdeclarative to ensure qml
plugin symbols are not discarded.
The same macros will be used in a qtdeclarative change to prevent
discarding of resources when linking to static qml plugins.
A cmake-based test case is added to verify that linking to static
libraries directly, without linking to the resource initializer
object libraries, works fine as long as the project code calls
Q_INIT_RESOURCE for the relevant resource.
This reverts commit bc88bb34ca.

Most of these are of trivial kind (loops over const locals).
The one that isn't, in cleanupTestCase(), is, however, also simple:
it's a loop over a local, too, but it would be too much churn to
change the initialization to make the container const, and the loop
body clearly doesn't modify the container, so just go with the
std::as_const() pattern here.

I'd previously understood CLDR's minimumGroupingDigits to mean the
most significant group must have that many digits. It turns out to
mean only that the first grouping separator doesn't get added unless
the more significant group has this many. Once we have one separator,
more can be added that do isolate a single digit.
In the process, I discover some of the prior arithmetic is incorrect;
it is now fixed. Added some basic testing, amended some existing
tests. In the process, fixed naming of some double validator tests.

This source file is included in four other test projects, so it makes
more sense to port it away from Q_FOREACH than to white-list it
everywhere it's used.
The change in ModelMoveCommand::doCommand() is trivial. I only dropped
the pointless top-level const of the loop variable as a drive-by.
The change regarding `parents` in ModelChangeChildrenLayoutsCommand's
doCommand() is also trivial, I just ported to braced initialization to
get the QList to be const. We're forced by the Qt API
(layoutChanged()) to use a QList here, therefore no array.
Ibid., the change regarding `persistent` is simple. The container
cannot be marked as const without a lot of churn to its initialization
(applying IILE, basically), but other than that, it's a local
variable, and the loop body clearly doesn't modify it.

"Never use a dynamically-sized container for statically-sized data."
Port the loop from Q_FOREACH (which can't deal with arrays) to ranged
for (which can).

There was a gap in its numbering, and the quick brown fix could do
with some competition.

This one isn't trivial, but straight-forward: the only place the
container is modified is in fill(). Like the setOpaqueChildren()
function, this is only called from top-level test functions, and, in
particular, not from event handlers (setAttribute() sends events).
That fill() doesn't clear() the container, even though the single
UpdateWidget instance is being reused across test functions, looks
wrong, but doesn't invalidate this analysis.

The Q_FOREACH is in a header, so we need to port away from it,
otherwise it makes any TU that includes it (in PCH builds: all)
incompatible with QT_NO_FOREACH.
This is a trivial case of marking the local constructor const, but go
a step further and replace the QList with a C array ("never use a
dynamically-sized container for statically-sized data"). Both
consumers of the container (after s/foreach/for/) can deal with array.

This is more readable and at the same time helps to eradicate some
more Q_FOREACH uses for an eventual global QT_NO_FOREACH for all Qt
sources (QTBUG-115796).
