[issue7005] ConfigParser does not handle options without values
Łukasz Langa luk...@langa.pl added the comment: This one is strange. Trying to set a None value through set() raises 'TypeError: option values must be strings' on both Python 3.2 and 2.7. A string value of 'None' behaves as expected (e.g. correctly). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7005 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue7005] ConfigParser does not handle options without values
Fred L. Drake, Jr. fdr...@acm.org added the comment: I've attached a diagnostic script that I ran with Python 2.4..3.2 (current py3k HEAD); there are two output variants: old style: [section] option = None new style: [section] option This is the output I get when running this script for each of those Python versions: 2.4.6 RawConfigParser: old-style output 2.4.6 SafeConfigParser: raised TypeError on set 2.4.6 ConfigParser: old-style output 2.5.5 RawConfigParser: old-style output 2.5.5 SafeConfigParser: raised TypeError on set 2.5.5 ConfigParser: old-style output 2.6.5 RawConfigParser: old-style output 2.6.5 SafeConfigParser: raised TypeError on set 2.6.5 ConfigParser: old-style output 2.7 RawConfigParser: new-style output 2.7 SafeConfigParser: raised TypeError on set 2.7 ConfigParser: new-style output 3.1.1 RawConfigParser: old-style output 3.1.1 SafeConfigParser: raised TypeError on set 3.1.1 ConfigParser: old-style output 3.2a1+ RawConfigParser: new-style output 3.2a1+ SafeConfigParser: raised TypeError on set 3.2a1+ ConfigParser: new-style output Essentially: For the RawConfigParser and ConfigParser classes, the output changes in 2.7 and 3.2, and in a way that should be considered incorrect because it conflicts with the allow_no_values setting. This is a bug and should be fixed in both 2.7 and 3.2. The TypeError-on-set is consistently raised only for SafeConfigParser, and should remain unchanged. (Why this was handled differently for SafeConfigParser I don't recall offhand.) -- Added file: http://bugs.python.org/file18717/cpsample.py ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7005 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Fred L. Drake, Jr. fdr...@acm.org added the comment: Attached fix test for Python 2; adjusting to Python 3 is trivial. The test could be added to 2.6 as well to protect against regressions there, though that's unlikely to be a significant issue. -- Added file: http://bugs.python.org/file18718/issue-7005.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7005 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Dwayne Bailey dwayne+pythonb...@translate.org.za added the comment: This is causing a regression in our code. Previously when we write out our INI file for an entry that has a value of None we saw the following: value = None These are now stored as: value This is now causing a traceback in our code. But interestingly I haven't changed anything in our initialisation of ConfigParser, I would have assumed that I need to set allow_no_value for this to work in the new way that MySQL expects. I would have expected everything to work as it currently does in 2.6 unless I specifically request You can see the traceback of Virtaal under Python 2. in this bug: https://bugzilla.redhat.com/show_bug.cgi?id=622061 -- nosy: +dwayne ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7005 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
