* Rewrite QMap to use a RB treeLars Knoll2012-03-231-394/+428
| | | | | | | | | | | | | | | | | | | | QMap used to use a skiplist in Qt 4.x, which has variable sized nodes and we can thus not optimise using custom allocators. The rewrite now uses a red-black tree, and all allocations and tree operations happen in the cpp file. This will allow us to introduce custom allocation schemes in later versions of Qt. Added some more tests and a benchmark. Memory consumption of the new QMap implementation is pretty much the same as before. Performance of insertion and lookup has increased by 10-30%. iteration is slower, but still extremely fast and should not matter compared to the work usually done when iterating.

| * containers: add C++11-style c{begin,end}() as alias for const{Begin,End}()Marc Mutz2012-03-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | C++11 adds cbegin()/cend() functions for the same reason Qt has constBegin()/constEnd(). This patch adds these functions to the Qt containers with the same implementation as constBegin()/constEnd(). It also fixes the return types in the documentation of existing constFind() functions (documentation only). C++11 only adds cbegin()/cend() (and crbegin()/crend(), which Qt doesn't have). In particular, it doesn't add cfind(), so I didn't supply these, even though Qt comes with constFind(). This is a forward-port of https://qt.gitorious.org/qt/qt/merge_requests/1365.

* | Don't expect null d-pointer in destructorsJoão Abecasis2012-02-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The feature was introduced in commit 83497587b2 (2004, private history), to allow static containers to remain uninitialized until needed. This finishes reverting said commit. The feature had been silently removed from QByteArray and QString in commit a5a0985476 (2004, private history); removed from QList in aef03d80f7.

* Don't crash by modifying read-only shared_nullBradley T. Hughes2011-10-041-2/+2
| | | | | | | | | | | | | | | | | | | Functions that modify the d-pointer must detach or otherwise take measures to not modify the const, read-only shared_null. The setSharable(bool) function takes care to detach when setting sharable to false, but should avoid setting the sharable data member unless d is not the shared null. Similarly, QMap<Key, T>::setInsertInOrder() needs to detach if it is shared with the shared_null (the logic has been updated to be the same as setSharable()).
