This patch makes
_NormalAccessor
handle missingos
functions consistently. The specific functions which may be unavailable are:os.lchmod()
os.link()
os.symlink()
os.readlink()
Only user-facing change is that you'll now get a
NotImplementedError
rather than anAttributeError
whenpathlib
hits_Accessor.readlink()
andos.readlink
doesn't exist.https://bugs.python.org/issue39924
