e4d62651c2 Re-add QPropertyAlias functionality
As QPropertyAlias was public by accident in 6.0, we have to ensure that
it still works in 6.2.
This re-adds some tests for it, and reimplements the unlinking
functionality. To avoid performance regressions in hot-paths,
a new unlink_fast function is added, which behaves like the old unlink:
It ignores the special handling for QPropertyAlias, so that we can skip
the tag check. It is only used in QPropertyObserverNodeProtector and
clearDependencyObservers, where we already know the type of the
observer.

Fixes: QTBUG-95846
Pick-to: 6.2

17357856b5 QMetaEnum: write "proper code"
Rewrite keysToValue() as suggested by a comment:

- Don't use the moral equivalent of
     QString::fromLatin1(keys).split().front().toLatin1(),
  use QStringTokenizer over QLatin1Strings, removing lots of
  allocations.

- Use QL1S instead of raw char* and strcmp(), because that made the
  old code rely on NUL-terminated tokens after splitting, which is no
  longer the case when using QStringTokenizer.

- Use the new stringDataView() instead of stringData() to avoid
  QByteArray dtors littering the code.

- Extract Method parse_scope(), using high-level API operating on QL1S
  to see what it's actually doing, instead of previous low-level
  bit-pushing with char* and ints that did a good job of obfuscating
  the purpose of all the scanning.

- Extract Method lookup() as a lambda to make the main loop of the
  algorithm more readable.

- Extract Method className() to delay looking up the class name until
  it is required (and help with readability). This could be further
  optimized by memoizing the result, but I'm convinced that's not
  worth the effort.

The code now no longer allocates, but we still can't mark the function
as noexcept, because stringDataView() contains a Q_ASSERT, so the
function has preconditions.

Results show that the new code is up to 2x faster than the old, and
never slower (within measurement uncertainty):

'qt_foo' and use '\versionlessCMakeCommandNote qt6_foo' to refer to the
versioned command.  This avoids duplicating the command signature.

Use the new macro where applicable.

fd9a94594f QDir: add assert for nullptr ok parameter in qt_cleanPath
Found by CodeChecker.
The function returns early in case of empty path, but the bool
parameter is never updated in this case. It's not a problem
with the current codebase though.
As it's a static local function, the reasonable solution is just
to add an assert, so that we do not get hit in case of refactoring.

77bdce8496 Modify the internal rectangle drawing of CE_RubberBand
adjusted(1, 1, -2, -2) makes the rectangle smaller, but when
rect.x1-rect.x2 = 0. Then x1 + 1, x2-2 leads to x1> x2. This will
make the rectangle flip in advance. So there is a difference
between the updated area and the drawn area.

Add a judgment, when the rectangle we get is large enough, draw the inner rectangle.

d07742f333 QLibrary: use QStringTokenizer in isLibrary()
Rewrite the whole function for readability _and_ performance:

- Extract Method isValidSuffix() as a lambda

- Extract Method isNumeric() as a lambda

- Use a C array of QLatin1String instead of a QStringList to hold the
  statically-sized list of candidate suffixes. This has the nice
  side-effect that the compiler will now throw an error in case the
  #ifdef'ery yields zero candidates (C arrays cannot have no
  elements), e.g. when porting to a new platform.

- Last, not least, replace the parsing with a loop that makes clear
  what's going on and which is forward-iteration-only-compatible, so
  we can use QStringTokenizer directly, without toContainer() to get a
  random-access sequence.

Need to use the C++20 version of all_of(), since QStringTokenizer uses
sentinels instead of end-iterators.

Even though we use higher-level constructs now, the code is still more
efficient than the index-twisting we had before.

bd52059eef QMetaEnum: avoid quadratic behavior in valueToKeys()
QByteArray (thankfully) doesn't have the prepend "optimization", so
prepend() is a linear operation, calling it in a loop thus makes the
algorithm quadratic.

To fix, simply remember the parts in a QVLA (an upper bound on the
size of which is easily calculated) and then build the result by
reverse-iterating over the QVLA.

This join_reversed() function is possibly useful elsewhere, but I left
it locally in the unnamed namespace to ease cherry-picking.

The new stringDataView() function is more universally useful, too, and
will be used in a subsequent other change. It return QL1S instead of
QByteArrayView because the latter is scheduled to become a non-string
type, and already lacks certain features (e.g. qTokenize() doesn't
work on QBA, due to lack of a Qt::CaseSensitivity argument in
QBA::indexOf()). It's also a Qt 6 addition, so not available in
5.15. We can revisit this decision later, when QBAV (or, possibly,
QU8SV) has caught up.

Amends 05e0dfa006.

62572f0a18 Add note about ImCursorPosition/ImAbsolutePosition not including preedit
The cursor position as reflected by these two properties is not affected
by the offset of the cursor in the preedit area. That means that when
composing text, the cursor position stays the same, at the preedit

fa6e490374 macOS: Respect default marked text attributes
When the marked text was not an attributed string with built in styling
we used to fall back to a hard-coded underline style.

We now pick up the default marked text style via the markedTextAttributes
property of a temporarily created NSView, which by default is a yellow
background color.

The implementation in NSView respects text system configuration toggles
such as NSMarkedTextAttribute and NSMarkedTextColor, so by setting the
user default NSMarkedTextAttribute to "Underline" the marked text will
look like our old hard-coded default. This can be done in many ways,
including passing `-NSMarkedTextAttribute Underline` on the command
line, or by QSettings::setValue("NSMarkedTextAttribute", "Underline");

70df6052d8 tst_QPluginLoader: Simplify creating a fake pointer in fakeplugin.cpp
When assigning multiple variables to a specific section, both GCC
and Clang legitimately error out if those variables wouldn't end
up in the same section (e.g. if one of them is going to a read-only
section while the other one is going to a read-write section).

In C++, when a seemingly const variable needs dynamic initialization,
it needs to be stored in a read-write section.

Clang 13 changed internals for how some constants are materialized.
Now, when a variable is initialized with an expression containing
plain old fashioned casts, it is considered to be potentially
runtime initialized (at the point when section assignment conflicts
is evaluated). Therefore, Clang 13 errors out on fakeplugin.cpp
with errors like:

    fakeplugin.cpp:36:39: error: 'message' causes a section type conflict with 'pluginSection'
    QT_PLUGIN_METADATA_SECTION const char message[] = "QTMETADATA";
                                          ^
    fakeplugin.cpp:32:40: note: declared here
    QT_PLUGIN_METADATA_SECTION void *const pluginSection = (void*)(0xc0ffeec0ffeeL);
                                           ^

See https://bugs.llvm.org/show_bug.cgi?id=51442 for discussion
on the matter in Clang.

To simplify things, just initialize the fake pointers as regular
uintptr_t instead, avoiding the whole matter. This produces the
exact same contents in the section as before.

For what it's worth, the actual manually constructed metadata in
fakeplugin.cpp doesn't seem to have any effect on running the
QPluginLoader tests on either ELF or MachO right now.

which was supposed to separate the arguments and write them into

However, passing arbitrary arguments after "-P script.cmake" only worked
by accident and is not supported.  As soon as arguments are passed that
are valid CMake arguments, like -help or -G, the CMake call would fail.

Now, we let configure.bat and qt-configure-module.bat write the

6b6d42f6b8 CMake: Fix QT_ADDITIONAL_PACKAGES_PREFIX_PATH for cross-builds
The QT_ADDITIONAL_PACKAGES_PREFIX_PATH variable was introduced to
allow specifying extra locations to find Qt packages.

The reason it was introduced instead of just using CMAKE_PREFIX_PATH
is because the Qt6 component find_package call uses NO_DEFAULT_PATH
which means CMAKE_PREFIX_PATH is ignored.
We use NO_DEFAULT_PATH to ensure we don't accidentally pick up
system / distro Qt packages.

The paths from QT_ADDITIONAL_PACKAGES_PREFIX_PATH are added to the
find_package PATHS option in the Qt6 package, each
ModuleDependencies.cmake file and some other places.

Unfortunately that's not enough to make it work for cross-builds.

Imagine the following scenario.

  host qtbase, qtdeclarative installed in /host_qt
  target qtbase installed in /target_qtbase
  target qtdeclarative installed in /target_qtdeclarative

We want to cross-build qtlottie.

We configure qtlottie as follows
 /target_qtbase/bin/qt-configure-module /qtlottie_src -- -DQT_ADDITIONAL_PACKAGES_PREFIX_PATH=/target_qtdeclarative

We expect the target QtQuick package to be found, but it won't be.

The reason is that QT_ADDITIONAL_PACKAGES_PREFIX_PATH is added to the
PATHs option, but we don't adjust CMAKE_FIND_ROOT_PATH.

Without adding the new paths in CMAKE_FIND_ROOT_PATH, CMake will
re-root the passed PATHs under the existing CMAKE_FIND_ROOT_PATH,
which is QT_TOOLCHAIN_RELOCATABLE_INSTALL_PREFIX, which evaluates to
/target_qtbase. There is no QtQuick package there.

To fix this, prepend the values of QT_ADDITIONAL_PACKAGES_PREFIX_PATH
to CMAKE_FIND_ROOT_PATH.

The location where we currently do CMAKE_FIND_ROOT_PATH manipulations
is in the qt.toolchain.cmake file, so to be consistent, we prepend the
new prefixes there as well.

We need to adjust both CMAKE_FIND_ROOT_PATH and CMAKE_PREFIX_PATH,
due the path re-rooting bug in CMake.
See https://gitlab.kitware.com/cmake/cmake/-/issues/21937 as well as
the existing comment in qt.toolchain.cmake marked with
REROOT_PATH_ISSUE_MARKER.

We also need to do a few more things to make the setup work

Because Qt6Config uses NO_DEFAULT_PATH, the CMAKE_PREFIX_PATH
adjustments we do in the toolchain file are not enough, so we still need
to add the same prefixes to the Qt6Config find_package PATHS option.

One would ask why do we need to adjust CMAKE_PREFIX_PATH at all then.
It's for find_package(Qt6Foo) calls to work which don't go through
the Qt6Config umbrella package.

To make the CMake re-rooting behavior happy, we need to ensure the
provided paths are absolute.
So we iterate over the values of QT_ADDITIONAL_PACKAGES_PREFIX_PATH,
to make them absolute. We do the same for the environment variable.

We need to append lib/cmake to the prefixes which are added to
CMAKE_PREFIX_PATH, otherwise the CMake re-rooting bug is hit.

We need to specify the Qt6 package location (${_qt_cmake_dir}) to the
PATHS option in the various Dependencies.cmake.in files, to ensure
that dependency resolution can jump around between the Qt6 dir and
the additional prefixes. Previously the dependency lookup code assumed
that all dependencies would be within the same prefix.

The same is needed for qt and qml plugin dependency lookup.
