Hi, I have investigated further the ABI issues reported for numpy 1.4.0. I can confirm that we have broken the ABI for 1.4.0 compared to 1.3.0 (besides the "trivial" cython issue). The good new is that I have found the issue, the bad news is that I don't know how to (cleanly) fix it.
The problem was caused by the new datetime support, in particular the structure PyArray_ArrFuncs which has been modified in a ABI-incompatible way (the first member cast is bigger because NTYPES is bigger). I don't know how to fix this cleanly - the only solution I can see is to to split cast into two parts, the first part the same size as before and the second part at the end of the structure, with a double-case test everytime the cast member is accessed inside the relevant functions.... As an aside, I would like to reiterate my advice for *small* commits. It took me nearly 2 hours to find this because the offending commit was > 4000 LOC, and it would have been very easy to find this were the code committed as a set of small self-contained commits. thanks, David _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
