Category: Python Library Group: Platform-specific Status: Open Resolution: None Priority: 5 Submitted By: Stephen Bennett (sbennett) Assigned to: Nobody/Anonymous (nobody) Summary: os.path.exists returns false negatives in MAC environments. Initial Comment: In Mandatory Access Control environments (such as SELinux), it's quite possible for stat to fail with permission denied. In this case, os.path.exists will return False incorrectly. The simple(ish) fix is to check for an access denied error (which would indicate present, but not readable) when using stat to check for existence of files. ---------------------------------------------------------------------- Comment By: Terry J. Reedy (tjreedy) Date: 2005-02-16 15:26 Message: Logged In: YES user_id=593130 Does 'access denied' always mean 'present but not readable' in every environment that gives such messages? I ask because I have vague memories of wasting time trying to get access to something that did not exist, because access denied (or something like that) meant that I was denied access even to info about whether it existed or not. In any case, a reproducible example would help someone to verify, fix, and write a test case for this if it is deemed to be a fixable bug. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1117601&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
