STINNER Victor added the comment: Attached patch raises a ValueError if the current recursion depth is higher than the new "low-water mark". The low-water mark is the value computed by _Py_MakeEndRecCheck() in Py_LeaveRecursiveCall() to decide if we can reset the overflowed field of the thread state to 0.
Example of error with the patch: $ ./python -c 'import sys; sys.setrecursionlimit(2)' Traceback (most recent call last): File "<string>", line 1, in <module> ValueError: cannot set recursion limit to 2: the minimum recursion limit is 1 at the recursion depth 1 ---------- keywords: +patch title: "./python -m test test_sys": Fatal Python error: Cannot recover from stack overflow -> sys.setrecursionlimit() must fail if the current recursion depth is higher than the new low-water mark Added file: http://bugs.python.org/file40640/sys_setrecursionlimit.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25274> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
