New submission from Stefan Krah <stefan-use...@bytereef.org>: I think that certain FileIO methods should raise IOError instead of ValueError when a file operation is attempted with the wrong mode. The methods of IOBase are documented to raise IOError in these situations.
>>> import io >>> f = io.open("testfile", "w") >>> f.read() Traceback (most recent call last): File "<stdin>", line 1, in <module> IOError: not readable >>> >>> f = io.FileIO("testfile", "w") >>> f.read() Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: File not open for reading ---------- components: IO messages: 98909 nosy: pitrou, skrah, stutzbach severity: normal status: open title: fileio.c: ValueError vs. IOError with impossible operations type: behavior versions: Python 2.7, Python 3.1, Python 3.2 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue7862> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
