* Don't crash by modifying read-only shared_nullBradley T. Hughes2011-10-041-1/+1
| | | | | | | | | | | | | | | | | | | 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()).

| | | | | | | | | | Similar to QLinkedList QList, QMap, QVector, QByteArray and QString, keep the shared_null in shareable memory and never modify it.

* don't calculate hash when the map is empty and we are not insertingOswald Buddenhagen2011-09-261-3/+6
| | | | | | | | | | | | the alternative would be splitting the function into two separate overloads. that might result in better branch prediction, but will create a bit more code.
