In my mind I don't think here is any problem. The code
val = PyBytes_FromStringAndSize (NULL, 20);
Py_SIZE(val) = 0;
doesn't create a zero length bytes object. A resizing I think should always means reorganizing the internal representation, including changing the size attribute. Using Py_SIZE won't trigger a full resizing. The code is not resizing but just breaks the internal representation and then leads to bugs. In C level, if you want, it's easy to muck Python objects. And exposing that much implementation details in documentation seems unnecessary. |
