Category: Python Library Group: Python 2.5 >Status: Closed >Resolution: Fixed Priority: 5 Submitted By: Wummel (calvin) Assigned to: Tim Peters (tim_one) Summary: "/".join() throws OverflowError Initial Comment: I noticed a regression in string.join() behaviour: Running under Python 2.4 works: $ python2.4 Python 2.4.4c0 (#2, Apr 22 2006, 22:39:06) [GCC 4.0.3 (Debian 4.0.3-1)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> "/".join([u"", u"2"]) u'/2' >>> Running under Python 2.5 SVN build fails: $ python2.5 Python 2.5a2 (trunk:46757, Jun 8 2006, 22:20:31) [GCC 4.1.2 20060604 (prerelease) (Debian 4.1.1-2)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> "/".join([u"", u"2"]) Traceback (most recent call last): File "<stdin>", line 1, in <module> OverflowError: join() is too long for a Python string >>> ---------------------------------------------------------------------- >Comment By: Georg Brandl (gbrandl) Date: 2006-06-10 06:45 Message: Logged In: YES user_id=849994 I applied the fix in rev. 46812. I also added the new test to the 2.4 branch in rev. 46813. ---------------------------------------------------------------------- Comment By: Tim Peters (tim_one) Date: 2006-06-09 00:34 Message: Logged In: YES user_id=31435 Fudge -- sorry about that! Your fix is fine. Adding two non-negative signed integers of the same width indeed overflows if and only if the computed result is negative. I was hallucinating when I imagined that a 0 result also indicated overflow (something related to that is a correct fast test when dealing with unsigned integers, but we're not here). ---------------------------------------------------------------------- Comment By: Hye-Shik Chang (perky) Date: 2006-06-08 22:40 Message: Logged In: YES user_id=55188 That occurrs when join sequence includes a zero-length unicode object after Tim's r46084. I attached a patch but can't sure that it's correct fix yet. :) ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1503157&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
