    Description

      Due to the use of lazy initalization (QDirPrivate::initFileLists()), QDir is not re-entrant. E.g. two threads calling QDir::count() on two independent, but shared, copies of a QDir object will cause a data race.

      Acceptance criteria:

      • QDir is ported to QExplicitlySharedDataPointer (to get const-correctness)
      • all internal lazy evaluation is protected from concurrent access
