Resize QPlatformWindow on DPI change, so that QWindow
size can stay approximately constant.
For example, a 100x100 QWindow at 100% scaling will
have a 100x100 QPlatformWindow. If the scaling is changed
to 200% then the QPlatformWindow is resized to 200x200,
while the size of the QWindow stays at at 100x100.
In practice the QWindow size will also change slightly,
due to inaccuracies in how we adjust for the size of the
non-client window area. This will be addressed in a later commit.
We can get DPI change independently of screen change,
so no resizing should happen in screen change events.
Disable the resize code in QGuiApplication for Q_OS_WIN,
and remove the WithinDpiChanged flag.
The new flow for handling DPI change is:
1) Send screen change (if any), so that the correct
screen will be used when calculating scale factors
during the following resize.
2) Resize the native window, which will trigger geometry
change events, possibly also for the QWindow.
3) Resize child windows; WM_DPICHANGED is sent to
top-level windows only.

necessitated by Qt's deviation from the STL of allowing insert() to

Since QMap these days is a wrapper around std::map, fix by using the
real thing (a std::map) instead, which sports the non-broken insert()
semantics already, avoiding the need to play tricks like detecting a
size increase in order to find whether an insertion took place. It
also simplifies the loop later on, and we can transparently use pmr,

The original Ant JUnit reporter produced test durations via Double.toString(),

as xs:decimal.
Sadly, the now popular Maven Surefire reporter limited the duration to
millisecond precision, and hard-coded this into its schema as SUREFIRE_TIME:

Unfortunately this definition spread into tools such as the Jenkins xUnit
plugin, which relies on the schema provided by Maven Surefire:
https://issues.jenkins.io/browse/JENKINS-52152
As a result, anything that produces higher precision results will not
validate in the Jenkins xUnit plugin.

The JUnit test framework did not initially have any XML reporting

Many users interacted with these reports via the Jenkins JUnit plugin,

- The 'hostname' attribute on <testsuite> is now included
- The 'classname' attribute on <testcase> is now included

- The non-standard 'result' attribute on <failure> has

- The <system-out> element on <testsuite> is always included,

- The non-standard 'tag' attribute on <failure> has been

It makes no sense for the event loop of a test to keep running after a
test has failed. This lets test code simply use the usual testlib
macros to compare and verify values in asynchronous tests that would
otherwise need to hand-test values and send a signal on failure (that
the main test can connect to an event-loops quit() or equivalent).
For example, QLocalSocket's benchmark simply uses the usual macros,
without doing anything to stop its event loop if they fail, with the
sad result that, when a test fails, it does so repeatedly and then
times out, causing the test program to be killed without running later
tests. With this change, that test code (once converted to use
QTestEventLoop) is able to exit gracefully on the first failure.

To retain backwards compatibility with some QNetworkReply usage,

With this patch users can now avoid this double decompression if the
amount of buffered data stays below 10 MiB. This means any file smaller
than 10 MiB will never need to be decompressed twice to know the size of
it. On top of that, if the data is handled as it arrives (e.g. in
readyRead) and the buffer is kept below 10 MiB it won't need to
decompress twice either.
This is active as long as "countDecompressed" is true, though it
currently always is in QNetworkAccessManger, with a future goal to make
it possible to control with public API. Since it requires the user to
potentially adapt their usage of QNetworkReply.
In this patch we also stop tracking the amount of unhandled uncompressed
bytes (uncompressedBytes) in favor of tracking the total amount of bytes
which has been read() by the user of QDecompressHelper (totalBytesRead),
since we can more intuitively work out the total amount of unread bytes
using this value.

This theory is backed by our own QtTest self-test (tst_silent)

The only difference between QWARN() and qWarning(), besides the much

This change introduces new behavior to error out when configuring user
projects if the CMake version used is too old for Qt to work with.
The main motivator is the requirement of new CMake features to ensure
object libraries are placed in the proper place on the link line in
static builds.
The minimum CMake version is computed based on whether Qt was
configured as shared or static libraries.
At the moment the required versions for building and using Qt are the
same.
The minimum versions are defined in qtbase/.cmake.conf in the
following variables
QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_BUILDING_QT_SHARED
QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_BUILDING_QT_STATIC
QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_USING_QT_SHARED
QT_SUPPORTED_MIN_CMAKE_VERSION_FOR_USING_QT_STATIC
Qt Packagers can disable the version check when configuring Qt
by setting
QT_FORCE_MIN_CMAKE_VERSION_FOR_BUILDING_QT and
QT_FORCE_MIN_CMAKE_VERSION_FOR_USING_QT.
In this case it is the packagers responsibility to ensure such a Qt
works correctly with the specified CMake version.
User projects can also set QT_FORCE_MIN_CMAKE_VERSION_FOR_USING_QT
to disable the version check. Then it's the project's developer
responsibility to ensure such a Qt works correctly.
No official support is provided for these cases.
Implementation notes.
The versions required to build Qt are stored in
QtBuildInternalsExtra.cmake
whereas the versions required to use Qt are stored in a new
QtConfigExtras.cmake.
Also the policy range variables stored in
QtBuildInternalsExtra.cmake are now regular variables instead of cache
variables, to properly allow overrides per-repository.
Some renaming of functions and variables was done for a bit more
clarity and easier grep-ability.

Building a static library Qt configuration will now require a
minimum CMake version of 3.20.
Qt builders and packagers can still opt out of the mentioned minimum
required version by configuring Qt with QT_FORCE_MIN_CMAKE_VERSION.
Such a Qt configuration is /NOT SUPPORTED/.
To facilitate these changes, the minimum version check has been moved
to happen after the BUILD_SHARED_LIBS option is computed by either
QtAutoDetect.cmake or set by a user provided cmake toolchain file.
Introduce a new QT_MIN_SUPPORTED_CMAKE_VERSION_FOR_STATIC_QT variable
in .cmake.conf to mark the minimum version for a static Qt build.

In order to filter out file names based on the user's settings,
QFileSystemModel used to have a loop that tested if a given file
name matched one of the filters. The problem is that each filter
(a wildcard) was converted to a QRegularExpression _inside_ the loop.
This causes a quadratic behavior (number of files * number of filters).
Instead, build the regexps once when the filters are set (or the case
sensitivity is changed, as that affects the filtering), and simply
_use_ them in the loop.
Simplify and correct some related code as a drive by.

The port from hand-rolled function storage to std::function
inadvertently removed the helper variable of static storage duration
whose dtor would unregister the conversion function. This caused
QTBUG-94831, where the cleanup of conversion functions attempts to
call code (via std::function) from a library that has already been
unloaded.
Restore the 5.15 behavior by adding a static-storage-duration scope
guard to unregister the conversion and view functions from Qt upon
library unload (when static objects are destroyed). Unlike 5.15, only
install the scope guard upon successful registration, ensuring that
only the DLL which successfully registered its conversion function
unregisters it again.

Add some strategic std::move()s as a drive-by.
