| * QBrush: Fix UB (non-virtual dtor) in QBrush::detach()Marc Mutz2016-09-181-6/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the d-pointer, QBrush uses a QScopedPointer with a custom deleter that checks for QBrushData::style and casts the QBrushData pointer down to corresponding subclasses before calling delete on them. 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.

| | | | | | | | | | | | | | | | | | | | | | When the pixmap is initially from a higher device pixel ratio and it is being used on a window that does not have a device pixel ratio other than 1.0 set then the pixmap should also have it set to 1.0.

| * Limit glyph caches per QFontEngine to four per context, not four in totalTor Arne Vestbø2016-08-242-35/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The limitation of four glyph caches per font engine was to prevent memory spikes during rotation of text. But in an application with multiple top level OpenGL windows, each with their own context, we'd end up trashing the list of glyph caches during rendering, even if each window just drew the same static text. Having a shared context between the windows helped a bit, but had other performance issues due to the globally shared state, so the better approach is to limit the caches to four per context. This brings the multiwindow manual test from a grinding 4fps on macOS to a smooth 60fps for 20 concurrent windows.

This would in turn invalidate the cache for every empty glyph, causing all glyphs to be rerendered for every isolated word. This change adds back a cut off. This is only needed in the lockedAlphaMapForGlyph() function, since the superclass implementation of the other alpha map functions already contains a cut off for width/height == 0. [ChangeLog][Qt Gui][Text] Fixed a performance regression in Freetype engine that was introduced in Qt 5.5.

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.

| | * QRasterizer: fix UBs involving << with a negative LHSMarc Mutz2016-07-301-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Left-shifts of negative values are undefined in C++. In particular, they don't behave arithmetically. Reported by UBSan: qrasterizer.cpp:609:48: runtime error: left shift of negative value -640/-2240 qrasterizer.cpp:982:38: runtime error: left shift of negative value -2 Fix by using ordinary multiplication instead, because negative left-hand-side values don't look like they are an error. 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.
