Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: Core (C code) Group: Python 2.5 Status: Open Resolution: None Priority: 7 Submitted By: Collin Winter (collinwinter) Assigned to: Nobody/Anonymous (nobody) Summary: Fix for Lib/test/crashers/gc_inspection.py Initial Comment: The attached patch fixes the bug pointed out in crashers/gc_inspection.py, namely that gc.get_referrers() can be used to see objects (in this case tuples) before their built, leading to segfaults. The patch works by modifying Objects/abstract.c:PySequence_AsTuple, wrapping the call to PyIter_Next() with _PyObject_GC_TRACK/UNTRACK calls. This has the effect of hiding the being-created tuple from gc.get_referrers() while fetching the next item from the iterator. Also attached is a patch to crashers/gc_inspection.py itself, which allows the test to actually pass (the previous version would raise IndexErrors in the event the test passed). ---------------------------------------------------------------------- >Comment By: Collin Winter (collinwinter) Date: 2006-07-05 13:36 Message: Logged In: YES user_id=1344176 The improve_gc_inspection.patch file has been superseded by a patch attached to bug #1517663. The bug details another interpreter crash in the same vein as the one fix in tuple() by this patch. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=305470&aid=1517042&group_id=5470 _______________________________________________ Patches mailing list Patches@python.org http://mail.python.org/mailman/listinfo/patches
