Category: Regular Expressions Group: Python 2.3 >Status: Closed >Resolution: Wont Fix Priority: 5 Submitted By: Nick Maclaren (nmm1) Assigned to: Gustavo Niemeyer (niemeyer) Summary: r'\10' as replacement pattern loops in compilation Initial Comment: The following program loops under at least Solaris 9 on SPARC and Linux (kernel 2.6) in x86. From tracebacks, it seems to be in the internal compilation of the pattern r'\10'. from re import compile line = "" pat = compile(12 * r'(\d+)') ltarget = float(pat.sub(r'\10',line)) print ltarget ---------------------------------------------------------------------- >Comment By: Gustavo Niemeyer (niemeyer) Date: 2005-09-14 09:34 Message: Logged In: YES user_id=7887 It's fixed in the 2.4+, and there's a workaround for previous versions, so I'm closing that as wontfix for 2.3. ---------------------------------------------------------------------- Comment By: Reinhold Birkenfeld (birkenfeld) Date: 2005-05-31 11:45 Message: Logged In: YES user_id=1188172 Setting group to Python 2.3. If there won't be a 2.3.6 in the future, it can be closed. ---------------------------------------------------------------------- Comment By: Nick Maclaren (nmm1) Date: 2004-11-02 13:28 Message: Logged In: YES user_id=652073 I have also checked, and it is fixed. From my point of view, it isn't worth backporting, as I can upgrade and don't mind using a beta version. ---------------------------------------------------------------------- Comment By: Michael Hudson (mwh) Date: 2004-11-02 13:07 Message: Logged In: YES user_id=6656 It does seem to be fixed in 2.4, but not in 2.3(.3, anyway). I know some of the re changes for 2.4 are fairly large, so I don't know whether the fix is a backport candidate for 2.3.5. Gustavo might know. ---------------------------------------------------------------------- Comment By: Johannes Gijsbers (jlgijsbers) Date: 2004-11-02 13:07 Message: Logged In: YES user_id=469548 I get the following on Python 2.4/Linux 2.6.8, so it does seem to be fixed: >>> from re import compile >>> line = "" >>> pat = compile(12 * r'(\d+)') >>> ltarget = float(pat.sub(r'\10',line)) Traceback (most recent call last): File "<stdin>", line 1, in ? ValueError: empty string for float() ---------------------------------------------------------------------- Comment By: Fredrik Lundh (effbot) Date: 2004-11-02 13:00 Message: Logged In: YES user_id=38376 If you need a workaround for 2.2, use a sub callback: http://effbot.org/zone/re-sub.htm#callbacks ---------------------------------------------------------------------- Comment By: Fredrik Lundh (effbot) Date: 2004-11-02 12:58 Message: Logged In: YES user_id=38376 Cannot check this right now, but I'm 99% sure that this has been fixed in 2.4. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1058786&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
