bc0c44d4cd _qt_internal_create_moc_command: Fix genex parse
The function was replacing the `>` character in generator expressions coming from `add_compile_definitions`. This was creating generator expression syntax errors. Discard generator expressions from character replacing.
Add tests for the three cases.

3965d52ad5 QTabBar: don't make current tab visible while tab bar is invisible
When changing the current index while the tab bar is not visible,
calculating the necessary scroll offset might result in wrong results if
the tab bar still has an old size. When the tab bar then gets shown and
resized, the scroll wouldn't be corrected, potentially leaving tabs
unnecessarily scrolled out.

We don't need to make the current index visible if the tab bar itself is
not visible, it's enough to flag the layout as dirty so that the next
show event (which either way makes the then current index visible)
triggers a laying out of the tab bar tabs.

c0c9e43be1 Add a special testcase for IndexedDB settings only
The test removes the file in memfs that IndexedDB settings use as the
backing store. This forces a new instance of IDB settings to read from

91e70f239e Give QLocale::uiLanguages() a separator parameter
It has always returned dash-joined forms of the locale names, and
callers who need an underscore-joined form have been obliged to
replace('-', '_') before using them. Given that everything it adds to
the list comes from QLocaleId methods that accept a separator, it's
trivial to let it offer the same choice to its callers and save them
this hassle.

Amended code in QTranslater and QMimeType to save them that hassle.

[ChangeLog][CoreLib][QLocale] QLocale::uiLanguages() now lets the
caller choose what separator to use between the tags that make up each
locale-identifier in the list returned.

d50fd6acfa tst_qdbusconnection: iterate over member container directly
The loops don't change the m_connections container. The call chain is:
- registerObjectPeer() unittest constructs a MyServer, which connects
  QDBusServer::newConnection to MyServer::handleConnection(), the
  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
  multiple times)
- server.unregisterObject() is called, iterating over m_connections
- server.registerObject() is called iterating over m_connections
- between the unregisterObject() call and the registerObject() calls
  m_connections is not modified AFAICS

Thus no need for taking a copy of m_connections (not that it matters
much, it's a QStringList with size() == 3).

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

ccd8a496cf QXmlStreamReader::readNextStartElement() - return false on document end
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.

=> Test correct behavior in tst_QXmlStream::readNextStartElement()

56bd5d60c9 Fix registration of QtDBus types' metatypes
By actually registering them.

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
for the parser, anyway.

Minor change to qdbuscpp2xml to allow reading from stdin, so we don't
have to create temporary files.

14d1108d35 Deprecate Q_ASSUME()
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.
To give a hint to the compiler for optimizations, use the C++23
[[assume]] attribute.

9c1d20337a Remove QUuid(quint128) constructor again
This constructor matches way too many argument types (integral,
unscoped enums, FP types), so it's likely to cause mayhem, even if
left in as an explicit constructor.

We now have a named constructor for the same functionality, so just
drop the "unnamed" constructor.

"Unnamed" constructors are important when emplacement is more
efficient than construction + move, or when implicit conversion is
required.  Neither is the case here: The named as well as the
"unnamed" constructors just copy ten bytes around, and the compiler
can optimize those extra copies away just fine.

Found in API review.

f2f8820073 tests: port assorted trivial uses of Q_FOREACH to ranged for loops
All of these fall into the trivial category: loops over (readily made)
const local containers. As such, they cannot possibly depend on the
safety copy that Q_FOREACH performs, so are safe to port as-is to
ranged for loops.

There may be more where these came from, but these were the ones that
stood out as immediately obvious when scanning the 100s of uses in
qtbase, so I preferred to directly fix them over white-listing their
files with QT_NO_FOREACH (which still may be necessary for some files,
as this patch may not port all uses in that file).

47375a213f QMimeDatabase benchmark: port away from Q_FOREACH
The original code duplicated contained elements of a QStringList by
repeated appending it to itself, preventing the container from being
marked const.

Instead, keep a list of unique mime-types, and iterate over the list
eight times.

As a drive-by, port from QList to a C array ("never use a
dynamically-sized container for statically-sized data"), use u""_s
UDLs (since we're touching almost all lines of the function, anyway,
also in the unrelated mimeTypeForName() call).

This allows porting the Q_FOREACH loop (which anyway cannot deal with
C arrays) to a ranged for one (which can).

This patch simplifies QPlainTextEditPrivate::updatePlaceHolderVisibility()

It replaces the member QPlainTextEditorPrivate::placeholderVisible
by the function isPlaceHolderTextVisible(). It returns true, if the
document is empty and a placeholder text exists, and otherwise false.
It adapts and corrects tst_QPlainTextEdit::placeHolderVisibility():
- usage of new member function instead of data member.

be3b9b2ab1 QAndroidPlatformInputContext: send composition text and cursor jointly
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.
The patch adds test functionality to tst_QLineEdit::setText().

47b879aa0b CMake: Place resources into static libraries, not object libraries
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.

Headers must be free of Q_FOREACH uses if we want to white-list only
those .cpp files that still use Q_FOREACH in order to enable
QT_NO_FOREACH by default.

In common.h, the situation is pretty clear: the loop bodies clearly
don't modify the container being iterated over.

In MyServer, the situation is not clear at all, and this author
doesn't have the time to investigate, so take a copy and iterate over
that (eactly what Q_FOREACH does), and leave a comment.

As a drive-by, fix missing {} around multi-line loop bodies.

3c38efbfe4 QByteArray: use new assign() in operator=(const char *)
operator=(~) and assign(~) share similar names but, until now, have not
shared the same functionality. This patch introduces the usage of
QByteArray::assign() within the non-sharing assignment operator to
effectively boost efficiency by reusing the available capacity.

Since these assignment operators are frequently used in many places,
both within Qt and non-Qt code, this patch comes with benchmarks.

The preview of the benchmark results are compared with this patch and
before this patch. The findings indicate a slight enhancement in
performance associated with the assignment operator. Despite the results
displaying only a minor improvement, progress has been made. Therefore
use assign(QByteArrayView) as replacement.

de94265169 Add QEXPECT_FAIL to tst_QApplication::sendEventsOnProcessEvents
Test sendEventsOnProcessEvents has been noticed to fail when
qgtk3 (Glib) is loaded - Should be fixed in QTBUG-87137

Moving test from blacklist to use QEXPECT_FAIL as it's more
recommended until test is fixed in the relevant configurations.

QEXPECT_FAIL is selected to use as original investigator
reported also some cases when glib is working. Therefore
this approach is giving us more insight for further
investigation is it always failing with glib or not.

It was also reported linkage to zeroTimer test QTBUG-84291,
but not sure why removing that has affected to this one.

Update to QEXPECT_FAIL documentation to tell in first place
that XPASS is not only marking it as XPASS but also failing
the test. Same is mentioned in different location but it
needs more searching or testing how it works in real test.

cc15e42e2c embeddedintoforeignindow test: port itemwindow.h away from Q_FOREACH
As a header, it would otherwise make all TUs that include it (with
PCH: all) incompatible with QT_NO_FOREACH.

Without deeper analysis (which economy of time forbids in this case,
given this is just a manual test that's probably run 10 times per
year), and seeing as this is in an event handler, I opted to play it
safe and iterate over a copy (which is exactly what Q_FOREACH
does). Added a comment to indicate it may not be needed.

the loop body clearly doesn't modify the container, so the protective

17dad4b88b QMimeDatabase benchmark: measure only what it pertinent
Drag the QCOMPARE (which even dynamically allocated a QString
fromLatin1()) out of the QBENCHMARK loop. Testing performance of
QString::fromLatin1() and/or qCompare() is not pertinent to the task
at hand, which, ideally, doesn't involve any memory allocations, so
there's at least the chance that this skewed the result noticably.

Didn't run the benchmark as this was developed on an asan build.

Yes, this breaks comparability with the stone-age measurements
reported in comments there, so sue me.

As a drive-by, replace the fromLatin1() with a u_s UDL.

1ae24f8b50 Use CLDR's names in QLocale::*ToName() for language, script, territory
Various comments need to continue using the enumdata.py names, as they
associate data with particular enum members, but we can now correctly
use the en.xml versions of their names when we report them, rather
than the enum-friendly names we use in the code. Since this now means
the data may stray outside plain ASCII - it'll be UTF-8-encoded - this
implies replacing the QLatin1StringView()s of the code that formerly
read this data with QString::fromUtf8().

d105c67a72 tst_QLocale: Use UTF-8 rather than Latin-1 for C-string-ification
Test names and output need to be UTF-8 for the XML data formats to not
end up malformed - which would upset Coin's testrunner, when it
validates the XML as part of checking - and the few other uses of
toLatin1() were to ASCII content anyway, so can harmlessly (this being
test code, where the slight performance advantage of Latin-1 doesn't
matter) use toUtf8() as well, for the sake of uniformity.

Use of toLatin1() broke an imminent commit in which some territory,
script and language names depart from ASCII, leading to malformed
UTF-8 when they appear in test-data-row names.

- 163af2cf53

Fix first and foremost by adding the missing ImageOption::ImageFormat
to the list of PNG-supported formats (which, curiously enough, predates
the public history and therefore the above three commits), and second,
by rewriting the whole test function to enable -Wswitch, so further
additions are less likely to be forgotten.

bb11f7a9fa QStorageInfo manual test: port away from Q_FOREACH
In main.cpp, the loop is over a local variable which would be const
were it not for the multi-step initialization that I didn't want to
change. The loop body clearly doesn't modify the container, so port to
ranged for loop with std::as_const().

In printvolumes.cpp, the loop _does_ invoke unknown code (through the
function pointer passed as the second argument), but, as could be
expected, the two users of the function don't pass functions that know
about `volumes`:

- in the tst_QStorageInfo auto-test, an rvalue `volumes` is passed,
  so we don't need to analyze the qInfoPrinter function passed there,
  as it cannot possibly reference the temporary

- and in main.cpp of the manual test, we just pass printf (which is
  technically UB (taking the address of a standard library function),
  but I don't care right now).

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.

f493b72ee7 DynamicTreeModel test helper: port away from Q_FOREACH
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.
