| * Improve readability of code that uses the Qt signed size typev5.10.0-rc2Simon Hausmann2017-11-281-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During the container BoF session at the Qt Contributor Summit 2017 the name of the signed size type became a subject of discussion in the context of readability of code using this type and the intention of using it for all length, size and count properties throughout the entire framework in future versions of Qt. This change proposes qsizetype as new name for qssize_t to emphasize the readability of code over POSIX compatibility, the former being potentially more relevant than the latter to the majority of users of Qt.

To this end, QSpanData gained a ref-counted pointer to the CacheInfo whose members it references to keep the object alive for as long as the QSpanData object needs it. However, since CacheInfo is only later defined in qpaintengine_raster.cpp, the counted pointer's payload was chosen as CacheInfo's base class, QSharedData. As it turns out, e.g. in the QPainter test, the data race was real and so QSpanData ends up being the entity that destroys (at least some) CacheInfos, either in its destructor, or in the setup() method. Since QSharedData's destructor is not virtual, and QExplicitlySharedDataPointer<QSharedData> knows nothing of the CacheInfo-ness of its payload, we end up calling the destructor of the base class, and not the CacheInfo one. Fix by using QSharedPointer instead, which stores the correct deleter internally. Ideally, QSpanData would contain a QSharedPointer<const void>, but QSharedPointer's implementation is deficient in that respect and does not compile when instantiated with void, and we can't use std::shared_ptr, yet, so introduce an arbitrary base class, Pinnable, to be used instead.

| | * Correct use of qt_div_255Allan Sandfeld Jensen2016-08-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | qt_div_255 does a fast rounded division, the form of rounding is however only valid for positive integers. Correct one case where it was used incorrectly and add it one place it would be valid, and adds a comment to the function. 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.

* | | Add qtguiglobal.h and qtguiglobal_p.hLars Knoll2016-07-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new modular configuration system requires one global header per module, that is included by all other files in this module. A similar scheme and naming convention is already being used for many other modules (e.g. printsupport, qml, quick). That header will later on #include the configuration file for Qt Gui. For now it defines the Q_GUI_EXPORT macro for this library. In addition, add a private global header, qtguiglobal_p.h, that can later on include the private config header for Qt Gui for things we don't want to export to the world.
