I suspect on Windows it is safe enough (in most cases) to use the
realpath as the key, in lieu of anything better. But that would require
testing on Windows to make sure. Can you try replacing the
GetRealpathAndStat in mplutil.py with the following?
class GetRealpathAndStat:
def __init__(self):
self._cache = {}
def __call__(self, path):
result = self._cache.get(path)
if result is None:
realpath = os.path.realpath(path)
if sys.platform == "win32":
stat_key = realpath
else:
stat = os.stat(realpath)
stat_key = (stat.st_ino, stat.st_dev)
result = realpath, stat_key
self._cache[path] = result
return result
get_realpath_and_stat = GetRealpathAndStat()
Cheers,
