The new codepath for the BYTEARRAY8 bytecode is missing memoization: >>> import pickletools, pickle >>> b = (bytearray(b"abc"), ) * 2 >>> b1, b2 = pickle.loads(pickle.dumps(b, 5)) # C version >>> b1 is b2 True (bytearray(b'abc'), bytearray(b'abc')) >>> b1, b2 = pickle.loads(pickle._dumps(b, 5)) # python version >>> b1 is b2 # :-( False Found it because PyPy is using pickle.py with no C implementation. I'm preparing a patch. |
