New submission from Xiang Zhang: List_New checks against PY_SIZE_MAX. The upper bound of PyMem_Malloc is PY_SSIZE_T_MAX.
Instead of simply changing the constant, another method is delegating overflow check to PyMem_Calloc, so we can avoid the check in unnecessary check in PyMem_Malloc. But I am not sure hiding the check in PyMem_Calloc is a good idea or not. ---------- components: Interpreter Core files: List_New.patch keywords: patch messages: 271774 nosy: martin.panter, xiang.zhang priority: normal severity: normal status: open title: Check against PY_SSIZE_T_MAX instead of PY_SIZE_MAX in List_New type: enhancement versions: Python 3.5, Python 3.6 Added file: http://bugs.python.org/file43962/List_New.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27662> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
