* Define inverted QRects consistentlyAllan Sandfeld Jensen2020-09-211-35/+79
| | | | | | | | | | | | | | | | Changes the definition of invalid QRects to be more consistent. This simplifies the logic, and makes it possible for us to fix normalized() so dimensions don't change. The actual API is not changed except for inverted rects. Only one use-case for the old normalized() function existed, and has been reimplemented as QRect::span().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ChangeLog][Source-Incompatible Changes] QProcess::setupChildProcess() was removed. To execute code in a child process, use QProcess::setChildProcessModifier() [ChangeLog][QtCore][QProcess] Added setChildProcessModifier() function with which one can provide code to be run in the Unix child process between fork() and execve(). With this function, it is no longer necessary to derive from QProcess in order to execute actions in the child process. Another reason is that we can tell whether the std::function carries a valid target much more easily than we can tell whether QProcess was overridden. The setupChildProcess() virtual function does not need to be marked final, since no overrider could ever return an inaccessible private class. This also makes sure the error presented to the user is about the return type, not about attempting to override a final. Clang: error: virtual function 'f' has a different return type ('void') than the function it overrides (which has return type 'QProcess::Use_setChildProcessModifier_Instead') GCC: error: conflicting return type specified for 'virtual void MyProcess::setupChildProcess()' note: overridden function is 'virtual QProcess::Use_setChildProcessModifier_Instead QProcess::setupChildProcess()' ICC: error: return type is neither identical to nor covariant with return type "QProcess::Use_setChildProcessModifier_Instead" of overridden virtual function "QProcess::setupChildProcess" MSVC is not relevant since it doesn't compile to Unix.

| | | | | | | | | | | | | | Just like any other container, it's legitimate for the user to pass key/values belonging to the same container. Q(Multi)Map::remove(Key) are already safe (either they call erase() directly on std::(multi)map, where it does the right thing, or they skip elements while detaching). However, QMultiMap::remove(Key, T) wasn't safe in this regard (the implementation is hand rolled), so take copies before start erasing.

Just use the implementation from the STL; we can't really claim that our code is much better than STL's, or does things any differently (de facto they're both red-black trees). Decouple QMultiMap from QMap, by making it NOT inherit from QMap any longer. This completes the deprecation started in 5.15: QMap now does not store duplicated keys any more. Something to establish is where to put the QExplictlySharedDataPointer replcement that is in there as an ad-hoc solution. There's a number of patches in-flight by Marc that try to introduce the same (or very similar) functionality. Miscellanea changes to the Q(Multi)Map code itself: * consistently use size_type instead of int; * pass iterators by value; * drop QT_STRICT_ITERATORS; * iterators implictly convert to const_iterators, and APIs take const_iterators; * iterators are just bidirectional and not random access; * added noexcept where it makes sense; * "inline" dropped (churn); * qMapLessThanKey dropped (undocumented, 0 hits in Qt, 1 hit in KDE); * operator== on Q(Multi)Map requires operator== on the key type (we're checking for equality, not equivalence!). Very few breakages occur in qtbase. [ChangeLog][Potentially Source-Incompatible Changes] QMap does not support multiple equivalent keys any more. Any related functionality has been removed from QMap, following the deprecation that happened in Qt 5.15. Use QMultiMap for this use case. [ChangeLog][Potentially Source-Incompatible Changes] QMap and QMultiMap iterators random-access API have been removed. Note that the iterators have always been just bidirectional; moving an iterator by N positions can still be achieved using std::next or std::advance, at the same cost as before (O(N)). [ChangeLog][Potentially Source-Incompatible Changes] QMultiMap does not inherit from QMap any more. Amongst other things, this means that iterators on a QMultiMap now belong to the QMultiMap class (and not to the QMap class); new Java iterators have been added.
