* Merge remote-tracking branch 'origin/5.7' into 5.8Liang Qi2016-08-291-0/+1

DirectWrite: Fix advances being scaled to 0 Since 131eee5cd, the stretch of a font can be 0, meaning "whatever the font provides". In combination with ec7fee96, this would cause advances in the DirectWrite engine to be scaled to 0, causing the QRawFont test to fail.

* | QGraphicsAnchorLayout: return a struct instead of a QListMarc Mutz2016-01-292-27/+20

The returned list was only ever exactly of size one or two, and two only if a local QList in the getGraphParts() function was not empty. Instead of using a QList to return those QLists, use a small struct of two QLists. This way, we avoid copying, memory allocations, and the code becomes a lot clearer, because we can give the members of the struct meaningful names, instead of at(0) and at(1). As a consequence, at the call site, the loop over the result can now be collapsed into an if. Saves ~1200b in text size on optimized GCC 5.3 Linux AMD64 builds.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QSimplexConstraints are held in QList everywhere, yet one single function, getGraphParts(), used a temporary QLinkedList. It did so because the function repeatedly walks the list, erasing elements from it until no more elements have been removed. Thus, in O-terms, QLinkedList is the correct choice here. Sadly, O-notation completely ignores the per-element cost, and this is where QLinkedList suffers. By the time a QList has shifted all of its elements left once, the QLinkedList probably has just finished allocating its first node. So, use a QList instead. That, however, turns the it = erase(it) loop quadratic, so re-formulate the processing part as a lambda and use std::remove_if. Don't even erase until we know how many items to erase. As a benefit, we save the final conversion of the remaining items back to a QList, and we can use QList::op+ to build the initial list, reducing the number of allocations performed by that container to one. Also saves ~770b in text size on optimized GCC 5.3 Linux AMD64 builds. Change-Id: Iecf9e7961dd2b6b20039b9b0d472e32b3fae6994 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC 5.3's undefined-behavior sanitizer checks that the declared type of the object is a base class of the dynamic type of the object on each access to a member of a class type. It therefore requires the typeinfo for these types, which for polymorphic types is emitted in the TU where the vtable is emitted, too. QFileDialogPrivate is a polymorphic non-exported class, so this failed at link-time. Ditto for the other cases. Fix by autotest-exporting the classs. Also, where applicable, de-inline the dtors, so the vtable (and typeinfo) are pinned to one TU, and the ctor, just because it's the correct thing to do.

* | QGraphicsView: replace some Q_FOREACH loops over rvalues with C++11 range-forMarc Mutz2015-12-236-45/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This needs to be handled a bit carefully, because Qt containers will detach upon being iterated over using range-for. In the cases of this patch, that trivially cannot happen, because all containers are marked as const when being assigned the rvalues previously found on the rhs of the Q_FOREACH. The new code thus does exactly what the old code did: take a const copy, then iterate over it. Separate patches will deal with other situations. Range-for loops are much more efficient than foreach loops. This patch shaves almost 4K of text size off an optimized Linux AMD64 GCC 4.9 build.

* | Optimize a code path in QGraphicsScenePrivate::cancelGesturesForChildren()Marc Mutz2015-12-221-19/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If ev.isAccepted(), since list is gestures.toList(), the first foreach loop would clear 'gestures', one item at a time. The second foreach loop would then not execute at all. Make this case clearer by not executing either loop if ev.isAccepted(). Make it more performant by not iterating twice, but once, simply skipping those gestures in the second (remaining) loop which would have been removed by the first one. Also iterate over the equivalent QList instead of the QSet, because the former is way more efficient. Text size savings are present, but minimal. The runtime savings are signficant, of course.

* | QGraphicsSceneBspTreeIndex: simplify the code of items()Marc Mutz2015-12-221-16/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old code dealt with a lot of special cases, probably to avoid detaching. But the only case where deep copies are avoided is if a) there're no freeItemIndexes b) there're no unindexedItems c) the sort order is neither AcendingOrder nor DescendingOrder, which is funny, since those are the only two values for Qt::SortOrder. The code checks for SortOrder(-1), but nowhere in Qt is such a sort order created. Ergo, the deep copy was _never_ avoided. So simplify the code by always building the result list from the two input lists by copying all non-null items. Saves over 2KiB in text size on optimized GCC 4.9 Linux AMD64 builds.

* | QGraphicsScene: prevent lots of detaching d/t editing of copiesMarc Mutz2015-12-221-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QTouchEvent::touchPoints() returns a const-&, but the old code took a copy, over which it then iterated, modifying the touch points, causing (necessary) detaches of both the list and the touch points. Befriend QTouchEvent and modify the list in-place, avoiding all detaches in the likely case that QTouchPoint contains the only copy of the touch point list. This is all the more important as the function is called once for every item-under-mouse in sendTouchBeginEvent(). Port to C++11 range-for as a drive-by.

* | QtWidgets: de-inline some more virtual dtorsMarc Mutz2015-12-212-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Helps pinning the vtable to a single TU, which can prevent false negative RTTI (incl. dynamic_cast and catch()). But mostly because it's rather pointless to have dtors of polymophic function inline. Most of the time, the code will be called through the vtable indirection, anyway (which also means that an out-of-line copy of the code needs to exist in any case). The inline method will only be used when the compiler can prove the dynamic type of an object. Saves ~1.5KiB in text size on optimized GCC 4.9 Linux AMD64 builds.

* | De-duplicate QGraphicsItemPrivate vtableMarc Mutz2015-12-182-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By making the destructor (usually the first non-inline, non-pure, virtual function, and therefore the trigger for most compilers to emit the vtable and type_info structures for the class in that TU) out-of-line, vtables and, more importantly, type_info structures for the class are pinned to a single TU. This prevents false negative dynamic_cast and catch evaluation. Since QGraphicsItemPrivate is already exported, users of this class are unaffected by the change, and since it's private API, we don't need to avoid adding code to the out-of-line destructor until Qt 6. Also saves ~2.5KiB in text size on optimized GCC 4.9 Linux AMD64 builds.
