QByteArray::reserve shows unexpected behaviour

    XMLWordPrintable

Details

    Description

      QByteArray shrinks its size, when its data is shared.
      When it's not shared it does nothing, like other containers, too.

      QByteArray test("0123456789");
QByteArray copy = test;
copy.reserve(5);
test.reserve(5);
qDebug() << "test: " << test;
qDebug() << "copy: " << copy;

      Output:

      test:  "0123456789" 
copy:  "01234"
