The FPS is now calculated and output on the command line in a single

25c9a6c9b4 QtWidgets: Fix enter/leave events on popup menus
If the sloppy menu popups - send the leave event to the last active
menu (except Cocoa), because only currect active menu gets enter/leave
events (currently Cocoa is an exception).

Check that the menu really has a mouse before hiding the sloppy menu -
don't rely on enter events.

This patch removes some unnecessary synthetic mouse enter/leave events
from QMenu which causes event duplications with different mouse cursor
position.

Refactor sloppy menu timer handling - start or restart timers on mouse
move events. Enter/leave events are not reliable.

Fixes:
- better enter/leave events handling for native widget actions,
- reduce duplicated enter/leave events for menu actions,
- better handle torn off sloppy menus.

a54d44298f QLatin1String: Fix UB (nullptr passed) in relational operators
Found by UBSan:

  qstring.h:1160:44: runtime error: null pointer passed as argument 1, which is declared to never be null
  qstring.h:1160:44: runtime error: null pointer passed as argument 2, which is declared to never be null

Fix by avoiding the memcmp() calls if there's a chance that they
might be called with nullptr.

While at it, also implement !=, >, <=, >= in terms of ==, <,
and add a test, because this particular UB was not fingered by
any of the QtCore test cases, but by a Qt3D one.

3370ab9119 Never return char variants when reading prepared MySQL statements
This has undesired effects when converting a QSqlRecord to JSON.
A char(0) e.g. has special semantics that are undesired when
reading a Tinyint column.

I don't think that returning bool for the special case of a
Tinyint(1) is required. This also did not happen before, and
is also not happening when not using a prepared statement.
Instead, a plain int/uint QVariant is returned.

This patch extends tst_QSqlQuery::integralTypesMysql to also
cover reading and writing booleans from/to a MySQL table column
of type Tinyint(1). Additionally, the reading is now also done
with a prepared statement and we also check the raw variant
value.

The broken behavior fixed by this patch was introduced by me in
commit 194403a348.

3b8df0ea44 QtWidgets: Send show/hide event to children on restore/minimize
Child widgets should get the show/hide event when the TLW changes its
state, because child widgets are also visible or invisible. This
restores the Qt4 behavior (fixes the Qt4->Qt5 regression).

Restoring/minimizing the TLW now sends the spontaneous show/hide event.

Show events are now handled also in the expose event handler in the
QWidgetWindow class, because the show event must occur before the
expose event to avoid possible flicker e.g. the OpenGL content. This
can happen e.g. on XCB platform. If the "WindowStateChange" event occur
before the expose event (e.g. Windows platform) then the code in expose
event handler will be ignored to prevent event duplications.

Added autotest.

2a6bea7a55 qcompilerdetection.h: retract Q_COMPILER_DEFAULT_MEMBERS for MSVC < 2015
Earlier versions of the compiler cannot default
move special member functions, even though we
also define Q_COMPILER_RVALUE_REFS for them.

Fix by retracting the less-often-used of the
two compiler feature defines.

Q_COMPILER_DEFAULT_MEMBERS is not used outside
QtBase in neither 5.6 nor 5.7 (5.8 is not
released at this time, so wasn't considered).
The same is true of the dependent macros
Q_COMPILER_DEFAULT_DELETE_MEMBERS and
Q_DECL_EQ_DEFAULT.

In QtBase, the three uses are:
1. in QAtomic*, where the user also requires
   Q_COMPILER_CONSTEXPR, which is not defined
   for any MSVC at this time,
2. for QEnableSharedFromThis, which is a class
   template with an alternative {} implementa-
   tion of the default constructor, and uncon-
   ditional user-defined copy special member
   functions.
3. The test of the corresponding functionality
   in tst_compiler, which this commit amends.

That means that neither of these two only uses
of the macro in Qt libraries are affected by
the change.

The reason we do this change, then, is that in
the future, we want to be able to more easily
restore move special member functions for
classes for which they are suppressed due to
user-defined dtors or copy special member
functions.

55ab276700 Major re-write of generate_expected_output.py
Restructured, separated the canonicalising of output lines out (into
an object that prepares the necessary regexes and replacements)
suppress more, changed the path-stripping to strip qtbase's parent
rather than os.getcwd() and took account of shadow builds (so both
source tree and build tree provide prefixes we want to strip from
paths).  Also cope with $PWD potentially having symlinks in it, where
os.getcwd() is canonical.

It's possible some output might name files elsewhere in the source
tree; these won't be filtered by the prior cwd prefix removal; and, in
any case, the problem with cwd is only that the ancestry of qtbase is
apt to vary; paths relative to there should be consistent between test
runs.  This change shall lead to a one-off rewrite of all expected_*
files; but it should now catch all paths.  By stripping both build
root and source root (when different) it also avoids differences for
those doing out-of-source ("shadow") builds.

In our XML formats, any hyphens in root paths (e.g. I had Qt-5.6 in my
build root's path) got represented by a character entity, confounding
the replacement; so also do replacement that catches this.  We may
discover other character entity subsitutions needed along with this.

Now filtering line numbers and timing information, including benchmark
results; these numbers all get replaced with 0 to avoid noisy diffs.
Also purging dangling hspace, to placate sanity-bot.

The module can now be imported - the code it runs is packaged as a
main() function that a __name__ == '__main__' stanza runs - and all
data is localised to where it's needed, rather than held in globals.
Tidied up and organized the existing regexes.  There are doc-strings;
there is a short usage comment.  Data is localised rather than global
and modern pythonic idioms get used where apt.

Regexes are compiled once instead of repeatedly.  An object looks
after the list of patterns to apply and its construction handles all
anticipated problems.  Failures are mediated by an exception.

The output file now gets written once, instead of twice (once before
editing, then over-write to edit), and Popen uses text mode, so that
write can do the same.  Its command is delivered as an array, avoiding
the need to invoke a shell.

Instead of relying on qmake being in our path (which might give us a
bogus QT_VERSION if the one in path doesn't match our build tree), use
the relative path to qmake - we rely on being run in a specific
directory in the build tree, after all.  Escape dots in the version
properly, so that 51730 doesn't get mistaken for 5.7.0 (for example),
and moved this check later in the sequence (matching a smaller target
makes it more likely to falsely match).

Overtly check we are in the right directory and tell the user what we
actually need, if run from the wrong place.  Simplify handling of the
unsupported use-case for MS-Windows (but note what would be needed for
it).

2a24c3c268 Fixed Bug in QVariant comparison when containing QStringLists
As it were, QStringLists were not handled explicitly when comparing
QVariants. If both QStringLists contained only a single entry, they
were treated as QStrings - if both QStringLists were empty, there were
equal (correctly so) - but if one of the QStringLists had more than
one entry, the compare function fell through to returning always 1.
As discussed here:  https://stackoverflow.com/a/38492467/3444217

Added rich comparison tests for all non-numerical, non-recursive
QVariants that support them (except QModelIndex and
QPersistentModelIndex)

5dc83974f7 tst_QTreeView: Fix UB (invalid downcast, member call)
As reported by UBSan:

  tst_qtreeview.cpp:2187:36: runtime error: downcast of address 0x7ffc15749f20 which does not point to an object of type 'PublicView'
    0x7ffc15749f20: note: object is of type 'QTreeView'

Fix by making the test a friend of QTreeView (and, for
Clang, of QAbstractItemView) instead.

49c8923282 QSortFilterProxyModel: Don't forward the hint from source's layoutChanged signal
We can't forward a VerticalSortHint or HorizontalSortHint hint, because we might
be filtering extra items.

The documentation of QAbstractItemModel::LayoutChangeHint states:

    Note that VerticalSortHint and HorizontalSortHint carry the meaning that
    items are being moved within the same parent, not moved to a different
    parent in the model, and not filtered out or in.

And some of the views rely on this assumption (QQmlDelegateModel for example)

What happens in the test is the following:
- 'model' emit the dataChanged signal when its data is changed.
- 'proxi1' QSortFilterProxyModelPrivate::_q_sourceDataChanged does not forward
  the dataChanged signal imediatly, it will instead first re-sort the model and
  call layoutAboutToBeChanged / layouChanged with the VerticalSortHint
- 'proxy2' would forward the layoutAboutToBeChanged with the hint, but in
  QSortFilterProxyModelPrivate::_q_sourceLayoutChanged, it will redo the mapping
  which will cause the changed data to be filtered.
So proxy2 can't forward the VerticalSortHint as it removed rows in the process.

8a33077853 QUrl: fix resolved() for data URLs
They look relative because the path doesn't start with a '/' but they
have a scheme so they shouldn't be combined as if it was one absolute
and one relative URL.

[ChangeLog][QtCore][QUrl] QUrl::resolved() no longer treats a URL with
a scheme as a relative URL if it matches this URL's scheme. This special
casing was incompatible with RFC 3986 and broke resolving data: URLs,
for instance.

f24cc53cc2 Fix for race condition in signal activation
There was a race condition between QObject::disconnect() and
QMetaObject::activate() which can occur if there are multiple
BlockingQueued connections to one signal from different threads and
they connect/disconnect their connections often.

What can happen in this case is:
T1 is in activate() method and T2 is in disconnect() method

T1                          T2
locks sender mutex
selects next connection
unlocks sender mutex
                            locks sender mutex
                            sets isSlotObject to false
creates QMetaCallEvent      derefs connection
posts event

Two things can happen here:
1. Connection can still be valid, but it will have isSlotObject==false
and callFunction will be used instead of slotObj
2. Connection can already be invalid

To fix it mutex unlock should be moved after QMetaCallEvent creation.

Also there is another case, when we don't disconnect but delete the
receiver object. In this case it can already be invalid during
postEvent, so we need to move mutex unlock after postEvent.

7bf002c3b3 Backwards compatibility fix: No default colormap for Mono QImages
This is a partial revert of a4e2f2e687.

That fix tried to avoid the risk of a crash in pixel() by ensuring
Mono QImages created with external data also got a default color
table. However, that broke usable behavior in existing code that was
painting in Mono QImages using color0/color1.

This commit reverts to the old behavior, and instead expands on the
checking in pixel() so that lacking color table is handled gracefully
for all indexed formats.

c14c149b51 Fix QTemporaryDir to handle Unicode characters on Windows
For platforms not providing mkdtemp(), QTemporaryDir relied on an implementation
of q_mkdtemp() operating on char *, converting back and forth using
QFile::encodeName()/decodeName() when passing the name to QFileSystemEngine.
This caused failures on Windows (which uses "System"/Latin1 encoding)
for names containing characters outside the Latin1 space.

Reimplement q_mkdtemp() to operate on QString, which avoids the conversions
altogether and also enables the use of larger character spaces for the
pattern.

Add tests.
