* QCharRef/QByteRef: warn when triggering the resizing operator= behaviorGiuseppe D'Angelo2019-05-191-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The whole reason of QCharRef/QByteRef existence is to have a magic operator=. This operator= delays the actual detach up to the moment something is written into the Ref, thus avoiding spurious detaches to the underlying string/byte array. operator= has also an extra feature, it allows this code to succeed: QString s("abc"); s[10] = 'z'; assert(s == "abc z"); This last behavior is *extremely* surprising. The problem with all of this is that this extra convenience is outweighted by the massive pessimization in the codegen for operator[]; by the maintenance burden (QChar APIs need to be mirrored in QCharRef, etc.), and, for the automatic resize, by the fact that it's an super-niche use case. Cherry on top, std::basic_string does not do that, and no Qt or std container does that. In other words: any other container-like class exhibits UB for out of bounds access. We can't just go and change behavior, though. This is something coming all the way back from Qt 2 (maybe even Qt 1), which means we can't deprecate it at short notice. This patch simply adds a warning in debug builds in case the special resizing behavior is triggered. While at it, removes some code duplication in QByteRef. [ChangeLog][QtCore][QString] The behavior of operator[] to allow implicit resizing of the string has been deprecated, and will be removed in a future version of Qt. [ChangeLog][QtCore][QByteArray] The behavior of operator[] to allow implicit detaching and resizing of the byte array has been deprecated, and will be removed in a future version of Qt.
