New submission from Alex Henrie <[email protected]>:
pysqlite_cursor_fetchall currently has the following bit of code:
/* just make sure we enter the loop */
row = (PyObject*)Py_None;
while (row) {
row = pysqlite_cursor_iternext(self);
if (row) {
PyList_Append(list, row);
Py_DECREF(row);
}
}
This can and should be rewritten as a for loop to avoid the unnecessary
initialization to Py_None and the redundant if statement inside the loop.
pysqlite_cursor_fetchmany has the same problem.
