Message293395
I just ran into this issue. I'm trying to write code like this:
(ctypes.c_char*bufferLen).from_buffer(buffer)
where buffer is a bytearray. When bufferLen is greater than 2GB I fail foul of this code in _ctypes.c
long length;
....
length = PyLong_AsLongAndOverflow(length_attr, &overflow);
if (overflow) {
PyErr_SetString(PyExc_OverflowError,
"The '_length_' attribute is too large");
Py_DECREF(length_attr);
goto error;
}
Surely this should not be forcing long on us. Can't it use PyLong_AsSsize_t or perhaps PyLong_AsLongLongAndOverflow? |
