Previously,
StateDirectory
usedPosixFilePermissions
to configure its directories' permissions which fails on Windows as its file system is not POSIX-compliant. This PR updatesStateDirectory
to fall back to theFile
API on non-POSIX-compliant file systems. The File API doesn't allow as much control over the permissions so they're as close as the API permits.The unit tests have been updated to also verify the behaviour on non-POSIX-compliant file systems.
