Issue 4764: open('existing_dir') -> IOError instance's attr filename is None (original) (raw)

Py2.4 and 2.5 (and probably other 2.x releases too):

try: f=open('existing_dir') ... except IOError, exc: print exc.filename ... None (expected result: "existing_dir")

Py3.0 (and possibly 3.1 too):

try: f=open('existing_dir') ... except IOError as exc: print(exc.filename) ... None (expected result: "existing_dir")

But no problems with: open('existing_dir', 'w') => exc.filename=='existing_dir' open('not_existing_file') => exc.filename=='not_existing_file'

Guess: It may be similar to issue #599163
