5dbcced3bf use bindir instead of libdir when launching tools on windows, take 2
this makes build dirs consistent with install dirs, which fixes
launching tests, examples, and build tools in some configs.

unfortunately, this makes prefix builds slower and their build dirs
bigger due to the DLLDESTDIR implementation being stupid (QTBUG-11435),
but i'm not inclined to fix that now. it isn't actually worse than for
non-prefix builds, so whatever.

da2c73ad2b Plug memleaks in tst_QWidget
We need to delete the style returned from QStyleFactory::create()

The alternative would have been to create this once, as a member
of tst_QWidget, but this is the minimal approach that ensures
behavior just as the old code, but without the leak.

The problem is that the casts are done outside the switch that
determines the event's type, so for any given event object, at least
any two of the casts are invalid.

This could actually be a real problem, because it's trivial for a
compiler to prove that these three lines unconditionally invoke UB, so
it has all the right in the world to decide to drop the complete rest
of the function, using this line of reasoning:

1. The only way for these three casts not to be UB is if event ==
   nullptr.

2. If event == nullptr, then event->type() invokes UB, so event cannot
   be nullptr.

3. The only way both can be true is if this code path is never
   taken. I can thus assume that

      object == state && event->type() == QEvent::Timer

   is always true, drop the check and execute the if block
   unconditionally (I need to call QEvent::type(), to satisfy the
   as-if-rule, but I needn't check its return value).

Fix by moving the casts where they belong: into each case of the
switch, where the type of the event has been checked to match the
target type of the cast.

  0x7ffda11f2220: note: object is of type 'QMouseEvent'

The code attempted to model the layout of a QEvent with another class
that allows public access to the memory location that (hopefully)
corresponds to QEvent::spont, gaining access by casting a QEvent
object to that specifically-crafted class.

Fix by the using the existing QSpontaneKeyEvent::setSpontaneous()
call, which, despite its name, works for all QEvent subclasses, and
which has already been fixed to not invoke UB (in bc087db).

bdb81d0bd1 Avoid re-use of QFileSystemMetaData instance in dir entry listing
We've observed that on machines with SELinux installed but disabled, the
behavior of readdir() changes slightly. In the case of tst_qdir's
entryList QDir::Hidden test case, the listing of the directory contents
returns DT_UNKNOWN for the files and (broken) symlink(s) that are
present. When SELinux is enabled, we do see DT_REG and DT_LNK. Our
fallback to DT_UNKNOWN however resets merely the knownFlags, it does not
reset entryFlags, as all the other cases do.

The bug comes when QDirIteratorPrivate::advance() re-uses the
QFileSystemMetaData instance across iterations, and this way we get the
entryFlags values from a previous iteration (with != DT_UNKNOWN) into
the evaluation of an entry with DT_UNKNOWN.

The more conservative approach to fixing this is here by assuming that
QFileSystemMetaData is not designed for re-use and re-initialize it
explicitly in the iteration.

time) than it was asked to use.

since the spacer is owned by the layout until we remove it).

In distributeMultiCell(), allocate the QStyle subclass on the stack so
the compiler cleans it up properly on all exit paths (was:
unconditional leak).

77eafa8d89 Plug memleaks in tst_QBoxLayout
In sizeConstraints(), QLayout::takeAt(), as the name suggests, doesn't
actually delete the item. We have to do that ourselves.

Likewise, in replaceWidget(), QLayout::replaceWidget() also doesn't
delete the affected item, but returns it. That's spectacularly bad API
design, but the leak is easy to fix: just delete the return value.

Caused by using a struct to get access to QWidgetPrivate::wasDeleted
using a cast.  That cast is invalid, of course, so simply use
QWidgetPrivate::get().

Caveat: we need a const version of that function, but that didn't
exist, yet, so added one.

8cd28ea885 QGuiApplication, platform plugins: don't modify AA_DontUseNativeMenuBar
The default should be false, meaning the application will prefer to
use a native menubar if the platform supports it.  The application
author can set it to true if he wants to always use a Qt-rendered
menubar instead; or, he can call QMenuBar::setNativeMenuBar().
Qt and its plugins should not override the author's wishes.
Instead, if the platform plugin cannot create a native menubar
for whatever reason, createPlatformMenuBar() will return null,
and QMenuBar will fall back to using a Qt menubar instead.
The application can check the result via QMenuBar::isNativeMenuBar().

QMdiArea when maximized inside a QMainWindow with an empty title
does not replace the main window's title if we are using native menus.
This behavior turned out to be the same on Unity as it is on macOS,
so the autotest needed adjustment to expect that behavior whenever
the menubar is native, not only on certain platforms.

tst_QMenuBar::allowActiveAndDisabled() tests a standalone QMenuBar.
In f92f78094 it was disabled on macOS, but on Ubuntu it passes as
long as we force it to be a non-native menubar, so it should pass
that way on macOS too.  Removed unused variable RESET to fix warning.

Fix by replacing Q_Q with the the equivalent expression for QDialog.

We can't re-use QDialogPrivate::q_func() here, since that is private,
and probably should stay like that.

Also fix an invalid member call in
QColorDialogPrivate::canBeNativeDialog():

by accessing the data member directly instead of through the Public API.

Fix the same code in QFileDialog, even though the autotest coverage is
too limited for UBSan to point that one out explicitly.

This commit amends abe8b4ab9b, in which
it should have been included in the first place...

Fix is simple: just perform the cast before delivering the event.
