Category: XML Group: None >Status: Closed >Resolution: Fixed Priority: 2 Submitted By: douglas orr (dougbo) Assigned to: Nobody/Anonymous (nobody) Summary: infrequent memory leak in pyexpat Initial Comment: In pyexpat.c, the macro call for the handler dispatch (my##NAME##Handler) for CharacterHandler allocates an object implicitly by calling one of the conversion-to- unicode routines. If there is a problem in the PyBuildValue, resulting in args == NULL, that object will be leaked. Low priority, but the macros probably need some reworking to handle this. ---------------------------------------------------------------------- >Comment By: Georg Brandl (gbrandl) Date: 2006-04-12 15:00 Message: Logged In: YES user_id=849994 This was fixed in response to bug [ 984722 ] Py_BuildValue loses reference counts on error, in rev. 36480. ---------------------------------------------------------------------- Comment By: Martin v.

Löwis (loewis) Date: 2002-03-28 23:20 Message: Logged In: YES user_id=21627 No, currently, it can only leak: the argument being passed will have an extra ref count, which supposedly will be consumed by the tuple. If something fails, some of the N arguments will have been stored in the tuple-under-construction, and will be released when the tuple is released. 'N' arguments not yet consumed will leak. Processing should continue in case of an error, and DECREF all N arguments. ---------------------------------------------------------------------- Comment By: Guido van Rossum (gvanrossum) Date: 2002-03-28 22:34 Message: Logged In: YES user_id=6380 Hm, the 'N' format code looks really scary. Can't it end up DECREF'ing an object too many times if something fails? ---------------------------------------------------------------------- Comment By: Martin v. Löwis (loewis) Date: 2001-06-09 11:48 Message: Logged In: YES user_id=21627 That seems to be a bug in Py_BuildValue: It should decref its N arguments if it can't create a tuple. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=416288&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
