Transition scheme for allowing PyArray_Diagonal to return a view
PyArray_Diagonal is changed to return a copy of the diagonal (as in
numpy 1.6 and earlier), but with a new (hidden) WARN_ON_WRITE flag
set. Writes to this array (or views thereof) will continue to work as
normal, but the first write will trigger a DeprecationWarning.
We also issue this warning if someone extracts a non-numpy writeable
view of the array (e.g., by accessing the Python-level .data
attribute). There are likely still places where the data buffer is
exposed that I've missed -- review welcome!
New known-fail test: eye() for maskna arrays was only implemented by
exploiting ndarray.diagonal's view-ness, so it is now unimplemented
again, and the corresponding test is marked known-fail.
