[Numpy-discussion] Fixing PyArray_Descr flags member size, ABI vs pickling issue
Mon Mar 5 21:53:05 CST 2012
This is following the discussion on bug
Essentially, there is a discrepency between the actual type of the
flags member in the dtype C structure (char) and how it is declared in
the descriptor table (T_INT). The problem is that we are damned if we
fix it, damned if we are not:
- fixing T_INT to T_BYTE. flag in python is now fixed, but it breaks
pickled numpy arrays
- not fixing it means that the value is broken at the python level.
Changing the flag to be an actual int would break the ABI.
I currently have this: https://github.com/numpy/numpy/pull/228
Which one is the more appropriate ? Maybe a deprecation warning for
1.7 and change it in 1.8 ?
Note that we can fix the hash issue with either solution,
