[issue46284] DirEntry returns invalid values for is_dir and is_file on NFS

[Nicolas SURRIBAS]

New submission from Nicolas SURRIBAS <nicolas.surribas at gmail.com>:

Hello,

I bumped into this strange behavior several times when using os.scandir on mounted NFS shares. I'm using Python 3.9.1

>>> path = b'/mnt/nfs_share/sdb1/System Volume Information/'
>>> l = list(os.scandir(path))
>>> print(l[2].name)
b'WPSettings.dat'
>>> print(l[2].path)
b'/mnt/nfs_share/sdb1/System Volume Information/WPSettings.dat'
>>> print(l[2].is_file())
False
>>> print(l[2].is_dir())
True
>>> print(os.path.isfile(l[2].path))
True
>>> print(os.path.isdir(l[2].path))
False
