89aa6e780a Fix determination of host_arch test binary
The host architecture detection binary's file extension is determined by
the host platform, not the target platform. Respect the host variable
that's set in configure.json.

This amends commit d9fb502.

605062b21f Fix MinGW cross-build with precompiled headers on Linux
We need localtime_r() in several places. To have this function
declared when including time.h, _POSIX_THREAD_SAFE_FUNCTIONS must be
defined. E.g. qdatetime.cpp includes unistd.h before time.h to define
said macro.

However, this falls apart when precompiled headers are used, because
of the following include chain in qt_pch.h:
qcoreapplication.h -> qobject.h -> chrono -> time.h

This patch ensures that _POSIX_THREAD_SAFE_FUNCTIONS is defined before
including time.h in qt_pch.h by including unistd.h early.

b426cff1e0 Make tst_QGraphicsItem painting tests most robust
Counting absolute paint events is fragile, as there are no guarantees
that a single call to QApp::processEvents only delivers a single paint
event to a widget. As of QTBUG-76566, we see that the items occasionally
receive three calls to paint, which can be simulated by activating other
windows while the test is running and waiting for events to be
processed.

Instead, verify that we do receive any paint events as the first test,
and then verify increments when we expect updates.

This also reverts change 24b9424adc.

59b29d03b2 Further stabilization of QGraphicsItem::cursor test
The QTest::mouseMove calls are not reliable, and seem to produce
flakiness, at least on WinRT. Removing them, and only depending on
handling of the synchronously delivered QMouseEVent for simulated
mouse moves.

Also, initialize the expected cursor shape from an empty scene;
this avoids that showing the view with the cursor accidentially
on an item results in the wrong default shape. Remove hard
coded coordinates, just test what we know.

0a3107dd30 QHostInfo: fix a race condition on QHostInfoCache::enabled
In auto-test-enabled builds, QHostInfoCache can be enabled and
disabled using qt_qhostinfo_enable_cache() at any time. We cannot rule
out that users use this function, or, indeed, that the auto-test never
gets a threading stress-test. Under the assumption, then, that
QHostInfoCache::enabled can be set by any thread at any time, and is
read by any thread using QHostInfo::lookupHost(), we're presented with
a data race, thus UB.

Fix by making the accesses to QHostInfoCache::enabed atomic. Relaxed
operations are suffcient, as the bool is the only data of interest in
these situations. In particular, access to the cache itself is
protected by the cache's mutex.

We use std::atomic<bool> because QAtomicInteger<bool> doesn't exist on
all implementations, but std::atomic<bool> must. Commit a0faf9e236 set
the precedent that it works.

is bad code hygiene and should be fixed come Qt 6.

The present patch is the result of compile fixes from marking these

an indication that they're not in widespread use elsewhere.

d8688d4484 Don't set the mouse cursor for items that are disabled
As with widgets, items that are disabled should not receive any input
events.

Similar to QGraphicsScene, which ignores disabled items when handling
mouse presses, the view should also ignore them when handling mouse
moves to update the cursor.

Since QGraphicsView only adjusts the cursors on mouse moves, reenabling
an item that is currently under the mouse will not change the cursor.
This is consistent with other changes of item attributes that would
position the item under the mouse (such as moving it). The overhead of
hit-testing items for every such attribute change would be too large,
and applications can generate a mouse move event if they really need
to adjust the cursor in all situations.

[ChangeLog][QtWidgets][QGraphicsView] Ignore disabled items when setting
the mouse cursor.

307403f8b4 Stabilize QGraphicsItem::cursor and select_multi tests
The tests send QEvent::MouseMove events to the view, but don't fully
construct the event with both local and global position. Consequently,
QMouseEvent will use QCursor::pos as the global position, which is
unreliable, as QTest::mouseMove can not guarantee that the mouse really
moves - when running the tests locally on e.g macOS, it never does.

So instead construct the QMouseEvent with the trivially calculated
global position.

8f75910dea Add mouseDoubleClickDistance and touchDoubleTapDistance to QStyleHints
Amends ca280bfe3b and
705e3f68df which added these enums only to
QPlatformTheme::ThemeHint but not to QPlatformIntegration::StyleHint.
Those patches did not add accessors to QStyleHints, probably because
the accessors in QStyleHints use the themeableHint() function which
takes both enums; so to have an accessor implemented this way, we need
it in both enums.  But it's getting too silly, since the only platform
plugin that modifies MouseDoubleClickDistance is Android, implemented by
QAndroidPlatformTheme overriding QPlatformTheme::themeHint(), and thus
illustrating that adding the enum to QPlatformIntegration::StyleHint
is not the only way to allow a platform plugin to customize the hint.

So it seems we need a new way of writing these accessors without needing
to duplicate the enum value in QPlatformIntegration::StyleHint.  The new
version of themeableHint(QPlatformTheme::ThemeHint) falls back on the
static QPlatformTheme::defaultThemeHint() accessor.

Users should at least be able to see what the default value is; and
having these getters will also provide link targets for QtQuick's
TapHandler docs.

events sometime between GUI thread has last time peeked at the queue and before
it has called waitForNewEvents() and hence started waiting for more events (via
QWaitCondition). This scenario is even mentioned in the QWaitCondition documentation:

"[..] if some of the threads are still in do_something() when the key is pressed,
they won't be woken up (since they're not waiting on the condition variable) and
so the task will not be performed for that key press. [..]"

And if there are no more events on the X11 connection, the waitForNewEvents()
in QXcbClipboard::waitForClipboardEvent() would timeout.

f14db5dd3a qsslsocket_openssl_symbols.cpp: replace mutex pool use with QBasicMutex
The use of QMutexPool caused an #ifdef, because, lacking an object,
some OpenSSL function pointer was used as the address required as
input for the mutex pool. Sadly, the names of the functions differ
between OpenSSL versions, thus the need for an #ifdef.

By simply using a QBasicMutex (defined at namespace scope to evade
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79561), the #ifdef can go
away.

Another level of #ifdefs goes away because, even for
non-QT_CONFIG(thread) builds, Q*Mutex etc are defined, just as
no-ops. So we can freely use them without QT_CONFIG(thread) guard,
unlike QMutexPool.

Finally, optimize for the (common?) case of already-loaded libraries
by making symbolsResolved an atomic variable, and checking that before
taking the mutex (double-checked locking, done right).

For reasons of said GCC bug, again, the QBasicAtomic is defined at
namespace scope. And then move the other boolean there for symmetry.

07553d0353 QTextBrowser: assume Markdown is UTF-8
That's how CommonMark specifies it.  The HTML codec-guessing algorithm
was making it fall back to Latin1 in practice, which was screwing up
any Unicode characters found in the markdown source.

3a1f9dec7c Q_ARRAY_LITERAL: protect the check for literal types
Some compilers (hello, MSVC) do not produce literal types in Qt
because their constexpr support has been blacklisted.
Therefore, amend the check for literal types in Q_ARRAY_LITERAL:
only do the check if the compiler supports constexpr.

eea99e1e8f Fontconfig font database: Short-circuit matching by filename
If the filename matches, no other matching is necessary. Fontconfig
doesn't have a fast path for that, so implement one here.
Fontconfig is unlikely to add that fast path, see here:
https://gitlab.freedesktop.org/fontconfig/fontconfig/issues/103

With -O1 builds of Qt and KDE stack, 358 fonts installed according
to KDE systemsetting, on a Ryzen 1800X, startup time of kwrite
decreases as following according to perf stat:
msec task-clock: ~480 ms to ~455 ms
cycles: ~1.73e9 to ~1.65e9

95310aac6d Short live QRecursiveMutex!
Move the recursive mutex use case out of QMutex into a separate class,
unsurprisingly called QRecursiveMutex. As an immediate benefit, 90% of
the QMutex users now enjoy a constexpr QMutex ctor.

This change prepares for a real split in Qt 6, so that both use-cases
are no longer bundled up in one class.

[ChangeLog][QtCore][QMutex] Added QRecursiveMutex as a replacement of
QMutex(QMutex::Recursive).
