fad814088c do not wrap QAbstractEventDispatcher::flush with QT_DEPRECATED_SINCE
... as this would require us to remove usage of QAbstractEventDispatcher::flush
from Qt source code as well. We can not do this already in Qt 5.9 as there are
few event dispatchers in Qt that actually do override the ::flush (with non empty
bodies). Removing this code could result in behavior changes (not very likely) for
some user code. This method will be removed in Qt6.

Instead mark it with a well known "### Qt{Version}" comment.

This patch amends 41eefd7. The warning was:

qcoreapplication.cpp: In static member function ‘static void QCoreApplication::flush()’:
qcoreapplication.cpp:733:48: warning: ‘virtual void QAbstractEventDispatcher::flush()’ is deprecated [-Wdeprecated-declarations]
         self->d_func()->eventDispatcher->flush();

9e2c6899e0 QUrl: fix IDN conversion when the ACE form is invalid
We guarded against the Unicode form being invalid and did not produce an
encoded form. But we did not guard against proper Punycode sequences
that decode to forms that had not passed the proper Nameprep stage. So
check for that and, if it fails, just keep the label in the form we
found it in (it's valid STD3 anyway).

41eefd7493 Deprecate QCoreApplication::flush()
... as it has outlived its original purpose:

Qt3 implementation on X11:
void QApplication::flush() { flushX(); }
void QApplication::flushX() { if (appDpy) XFlush( appDpy ); }

Qt4 implementation on X11:
Did nothing when QApplication::flush() was called (the flush()
overrides in {unix,glib} event dispatchers with empty bodies).

In Qt5 this function somehow has been repurposed (inconsistently)
to do what QCoreApplication::sendPostedEvents already does:

QAbstractEventDispatcher::flush() = 0;
 => QCocoaEventDispatcher::flush() {}
 => QEventDispatcherCoreFoundation::flush() {}
    => QIOSEventDispatcher (does not override ::flush())
 => QEventDispatcherGlib::flush() {}
    => QPAEventDispatcherGlib (does not override ::flush())
 => QEventDispatcherUNIX::flush() {}
    => QUnixEventDispatcherQPA (when QT_NO_GLIB=true)
       ::flush() { if (qApp) qApp->sendPostedEvents(); })
       ==> QAndroidEventDispatcher (does not override ::flush())
 => QEventDispatcherWin32::flush() {}
    => QOffscreenEventDispatcher::flush() {
         if (qApp) qApp->sendPostedEvents();
         QEventDispatcherWin32::flush();
       }
    => QWindowsGuiEventDispatcher (does not override ::flush())
       => QWindowsDirect2DEventDispatcher (does not override ::flush())
 => QEventDispatcherWinRT::flush() {}
    => QOffscreenEventDispatcher::flush() {
         if (qApp) qApp->sendPostedEvents();
         QEventDispatcherWinRT::flush();
       }
    => QWinRTEventDispatcher (qminimaleglintegration.cpp) (does not override ::flush())
    => QWinRTEventDispatcher (qwinrteventdispatcher.h) (does not override ::flush())

Whatever this function was doing on macOS in Qt3 and Qt4 also has been
dropped in Qt5. It appears that the other event dispatchers in Qt5 that
have overrides for flush() have simply copy-pasted this logic.

Clearly the documentation of QCoreApplication::flush() is outdated and
has nothing to do with the actual implementation in Qt5.

This function is rarely used in Qt5 sources. It should be safe to remove
the calls to QCoreApplication::flush() from Qt source code, as this
function has been doing nothing on most platforms anyways. Repurposing
it even broke handling of posted events (see QTBUG-48717).

[ChangeLog][QtCore][Event loop] QCoreApplication::flush() is now
deprecated. Use QCoreApplication::processEvents() and
QCoreApplication::sendPostedEvents() instead.

d4cdc45426 Fix QMetaMethod::invoke and automatic type registration

 - The index passed to QMetaObject::metacall was not right (there was an offset
   because of the return type)
 - If the registration succeeded, the arguments were not even initialized.

which was properly registering the type. So this was not seen in the tests before.

dfc2a4a537 QLoggingRegistry: remove rules vector
It only contained a concatenation of the individual rule sets,
probably to fix their order in a central place, as well as
simplifying iteration in defaultCategoryFilter().

Fix these two issues differently, but introducing a RuleSet
enum that lists rule sets in the order in which they should
be applied by defaultCategoryFilter(), and turn individual
rule sets vectors into a C array of vectors.

This enables two nested loops in defaultCategoryFilter to
replace the one loop over 'rules'. Apart from building up
'rules' in updateRules(), this was the only access to that
member. That leaves updateRules() with just the task of
running defaultCategoryFilter() on the new rule sets.
Consequently, a call to updateRules() can now replace the
identical loop in installFilter().

Performance should not suffer. Iterating over a fixed-size
array of vectors is hardly any slower than iterating over
a single vector, and while the construction of 'rules'
was probably a one-off task in most programs, this way
of keeping the rules also saves memory because rules are
not kept in two different vectors.

It is also more maintainable, of course.

126c4eae84 Split Q_COMPILER_UNICODE_STRINGS: add Q_STDLIB_UNICODE_STRINGS
Since commit bf2160e72c, we can rely on
charNN_t support in all compilers except MSVC 2013, and since that
commit, we use (in 5.10, not 5.9, yet)

  !defined(Q_OS_WIN) || defined(Q_COMPILER_UNICODE_STRINGS)

when we only need charNN_t, the type, as opposed to its library
support (u16string, char_traits<char16_t>, ...).

This patch splits the Q_C_UNICODE_STRINGS macro into two, adding
Q_STDLIB_UNICODE_STRINGS for when we need std::uNNstring, leaving
Q_C_UNICODE_STRINGS for when we need just charNN_t support.

In QDebug, when constructing a QChar out of a char16_t, cast to ushort
first, since QChar(char16_t) was only officially introduced in Qt 5.10.

[ChangeLog][Potentially Source-Incompatible Changes] The internal
Q_COMPILER_UNICODE_STRINGS macro is now defined if the compiler
supports charNN_t, even if the standard library does not. To check for
availability of std::uNNstring, use the new Q_STDLIB_UNICODE_STRINGS
macro.

We use QCoreApplication::applicationDirPath in the logging initialization to find

a QCoreApplication instance this leads to a qWarning, which in turn leads to a
recursive call to the logging initialization, and in turn to a recursive mutex deadlock.

46c66bce5d Optimize QLoggingSettingsParser
Factor the line parsing into a separate function, parseNextLine(),
taking a QStringRef.

In setContent(QTextStream&), use the new readLineInto() function to
re-use the capacity of a single QString for all lines.

In setContent(QString), use splitRef() to split the lines.

In either function, pass each line to parseNextLine().

In order to port all the parsing to QStringRef, I needed to make some
semantic changes: the old code removed all whitespace right at the
beginning. This is not possible with QStringRef. It also didn't feel
right, since a line like

   [    r u  l e s ]

would successfully parse as the section named "rules".

I added trimmed() calls at the beginning, and around the valueStr and
pattern extraction, which should be good enough.

Also, when a section is found, don't store it anymore. Instead, only
store whether it was the [rules] section, because that's all we'll
test for. That way, we don't have to convert QStringRefs to QString
just to store them across parseNextLine() calls.

Replace the setSection() function with setImplicitRulesSection(),
because "rules" is all that was ever passed.

This is private API, we can bring back some of the dropped flexibility
later, as needed.

[ChangeLog][Important Behavior Changes] Logging rules can no longer
contain arbitrary whitespace such as within a category identifier.

23d08ce2ed Fix QDir::mkpath() when the path contains "symlink/../"
It is incorrect to collapse a "symlink/.." segment because the parent
directory of the symlink's target may not be the directory where the
symlink itself is located.

[ChangeLog][QtCore][QDir] Fixed a bug that caused QDir::mkpath() to
create the wrong directory if the requested path contained a symbolic
link and "../".

795a54ff96 QDataStream: add operator<< and >> for std::nullptr_t
std::nullptr_t is nullary: it accepts only one value, nullptr. So we
don't need to read or write anything. This commit simply adds the two
operators that allow generic code to operate on std::nullptr_t if
required.

This commit also adds the actual use to QMetaType::load/save, even
though there's no change in behavior.

[ChangeLog][QtCore][QDataStream] Added operator<< and operator>>
overloads that take std::nullptr_t, to facilitate generic code.

280e321e52 Fix detection of F16C for the Intel compiler (again) and Visual Studio
Neither the Intel compiler nor Visual C++ have a dedicated switch to
enable F16C support, like GCC and Clang do. So we used the AVX switch
for that in commit 8241d51f70, as it was
the closest, lowest denominator. That was incorrect and insufficient.

The Intel compiler silently miscompiles the intrinsics with -xAVX,
making calls to out-of-line functions like _mm_cvtps_ph, which don't
exist. So we actually have to use AVX2 support to generate correct code.
That might be a problem later, since Ivy Bridge supports F16C but not
AVX2.

Visual C++ is able to generate F16C code with just -arch:AVX.

Either way, since there's no dedicated command-line switch, there's also
no dedicated preprocessor macro. We're using __AVX2__ for both
compilers, as that's a sufficient condition to indicate a processor that
supports F16C.

c817b33b45 f16c: Use the packed intrinsics instead of scalar ones
MSVC, Apple's Clang and Clang prior to 3.9 do not recognize _cvtss_sh
and _cvtsh_ss. So expand the operation to use directly the packed
intrinsics.
