Implementing PEP 3118 is somewhat convoluted because of the desirata:
-
Don't add new members to ndarray or descr structs, to preserve binary compatibility. (Also, adding the items is actually not very useful, since mutability issues prevent an 1 to 1 relationship between arrays and buffer views.)
-
Don't use bf_releasebuffer, because it prevents PyArg_ParseTuple("s#", ... from working. Breaking this would cause several backward compatibility issues already on Python 2.6.
-
Behave correctly when array is reshaped in-place, or it's dtype is altered.
The solution taken below is to manually track memory allocated for Py_buffers. </blockquote>
