Alex Trotsenko 6e8fcab7e0 Improve QIODevice::peek() performance on buffered devices ... Since 5.7, QIODevice::peek() implementation is based on transaction mechanism. While technically it's correct, seeking backward on a buffered random-access device clears the internal buffer that affects the performance of reading. To solve the problem, this patch implements peek mode directly inside the reading procedure.
