While hacking on Cython to make it recognize 'size_t' as a pre-defined
C integral type, I've found somethig that seems to be (pretty small)
inconsistency.
At Objects/longobject.c, you should see that in almost all cases
OverflowError is raised when a unsigned integral is requested from a
negative PyLong. However, See this one:
int
_PyLong_AsByteArray(PyLongObject* v,
unsigned char* bytes, size_t n,
int little_endian, int is_signed)
{
<...>
if (!is_signed) {
PyErr_SetString(PyExc_TypeError,
"can't convert negative long to unsigned");
return -1;
}
<...>
}
Does it make sense to change that code to raise OverflowError?
