[REG 4.8->5.0] Windows: QDir::cdUp() at network path root no longer returns false

    XMLWordPrintable

Details

    • f7b44f879cdded7b2c6b604df873f7194e56a63a , 101449a4cfa9c0d216332c6dc8ba826e8109e09d (qtbase/5.8, 12.12.2016, 5.8.1)

    Description

      QDir::cdUp() does not return false when going up from root of UNC network path. On local hard drive it does return false. In Qt 4.8 it also returns false when cdUp():ing on network path root.

      Steps to reproduce:

      • Run attached sample with valid network path as argument
      • EXPECTED: The while-loop exits when cdUp():ing first time from the network path root
      • ACTUAL: cdUp() never returns false, causing infinite loop
