| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Regression from 2d2d9078, which assumed the code in QBackingStore::beginPaint would apply to macOS as well, but QHighDpiScaling::isActive() is only active when Qt does the high DPI scaling, so we never hit the resize() code-path. Adds backingStore() accessor to go from QPlatformBackingStore to QBackingStore. Change-Id: I5de2ade74e731df445ea22e0f49b2a121e678efe Reviewed-by: Morten Johan Sørvig <morten.sorvig@qt.io>

| * | | QColor: provide QLatin1String overloads of functions taking QStringMarc Mutz2016-09-232-16/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The inefficiency of QColor(const char*) came to light by a recent refactoring which showed that the existing char* overload of qt_get_hex_rgb() was never called. So, provide a QLatin1String interface for named colors that allows user code to reach that internal function without converting to QString first.

Exception: it turned out that qt_get_named_rgb(const char *, QRgb*) wasn't actually used anywhere, but a follow-up commit will fix this. Adjust interface to that of the QChar overload (add explicit int len). Simplify conditional compilation of QT_NO_COLORNAMES: move the ifdef inside get_colornames, to avoid duplicating the declaration, and remove the empty implementation of get_named_rgb, since their use is already conditional on QT_NO_COLORNAMES not being defined.

In QBrush::detach(), however, any of the three brush data classes were held in a QScopedPointer _without_ the custom deleter, invoking UB when that scoped pointer would ever get to be the one that deleted the payload instead of handing it over to the objects d-pointer. Found by making dtors protected following a Coverity report wrongly marked as 'dismissed' (these static checks are not included in this patch, since they are binary-incompatible), to find out where Coverity could possibly see a problem. Also replace the d.reset(x.take()) that allowed this mismatch to compile with d.swap(x), which nicely ensures that x and d are of the same type.

We were using the optimization (x*a + y*(255-a))/255 == (x-y)*a/255 + y but that makes the division by 255 potentially negative.

However, it didn't check the return value of h2i() before attempting a left-shift on it, leading to UB when the first digit was already invalid. UBSan agrees: qcolor_p.cpp:55:23: runtime error: left shift of negative value -1 This is particularly worrisome as the function can be called with unsanitized input. Fix by checking each value for non-negativity, returning -1 early when errors are detected. Also port to QtMiscUtils::fromHex() and add some docs.

No errors were actually reported for a.y << 10, but I changed it nonetheless, since all a missing error means is that the test data didn't excercise this code path with negative Y values.
