bpo-35091: Objects/listobject.c: Replace overflow checks in gallop fu… (GH-10202)

2019-05-23T00:18:55+00:00

…nctions with asserts

The actual overflow can never happen because of the following:
* The size of a list can't be greater than PY_SSIZE_T_MAX / sizeof(PyObject*).
* The size of a pointer on all supported plaftorms is at least 4 bytes.
* ofs is positive and less than the list size at the beginning of each iteration.

closes bpo-35623: Fix integer overflow when sorting large lists (GH-11380)

2019-01-02T02:25:23+00:00

There is already a `Py_ssize_t i` defined at function scope that is used
for similar loops. By removing the local `int i` declaration that `i` is
used, which has the appropriate type.

This perhaps will fix similar problems in other extension types.
