Skip Montanaro <skip.montan...@gmail.com> added the comment: I was bitten by this porting a system from Python 2.7 to 3.6. "/dev/stderr" is a very nice default for logfiles. Users will frequently override the default, so you really want to open the logfile in append mode. Having to jump through hoops to avoid blasting a user's logfile is kinda dumb, and as others have pointed out, error-prone.
os.open works just fine with O_WRONLY|O_APPEND as the flags. /dev/null can be opened in append mode, but not /dev/stderr or /dev/stdout. ---------- nosy: +skip.montanaro _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue27805> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
