failure

PyMapping_Values() with an exception set, exit immediatly on error.

failure

CID 1128792: Dereference null return value (NULL_RETURNS)

CID 1128793: Missing varargs init or cleanup (VARARGS)

PyLong_FromLong() failure

error handling

The following code didn't handle correctly the failure of
PyUnicode_InternFromString("__name__").

if (newobj_str == NULL) {
    newobj_str = PyUnicode_InternFromString("__newobj__");
    name_str = PyUnicode_InternFromString("__name__");
    if (newobj_str == NULL || name_str == NULL)
        return -1;
}

the exception when PyList_Append() fails

- output type errors now redirect users to the type-neutral
  convenience functions in the codecs module
- stateless errors that occur during encoding and decoding
  will now be automatically wrapped in exceptions that give
  the name of the codec involved

Replace it with PyUnicode_GET_LENGTH() or PyUnicode_AsUnicodeAndSize()

failures

failure

PyUnicode_Substring() failure (ex: MemoryError)

test.support: considering the module is a mix of utilities unrelated with each other divide __all__ in sub-sections so that it can be used as a quick-reference doc
