In +particular, we killed support for the ``__cmp__`` special method and its +counsins, the ``cmp`` builtin function and keyword argument for +``list.sort()`` and ``sorted()``. Killing is easy, but then you have to fix +all the places which breaks because of this, including all the types which +relied on ``__cmp__`` to be comparable,, fixing all the tests which tried to +order objects which are no longer ordeable now, or implementing new behavior +like forbidding calling ``hash()`` on objects which implement ``__eq__`` but +not ``__hash__``. + +Among the other features, we killed lots of now-gone functions in the +``operator`` module, the builtins ``apply()``, ``reduce()`` and ``buffer``, +and the ``os.*`` functions to deal with temporary files, which has been +deprecated in favour of the new ``tempfile`` module. + +The other topic which can't miss in a py3k status update is, as usual, +string-vs-unicode. At this round, we fixed bugs in string formatting (in +particular to teach ``format()`` to always use unicode strings) and various +corner cases about when calling the (possibly overridden) ``__str__`` method +on subclasses of ``str``. Believe me, you don't want to know the precise rules +:-). + +Other features which we worked on and fixed tests include, but are not limited +to, ``marshal``, ``hashlib``, ``zipimport``, ``_socket`` and ``itertools``, +plus the habitual endless lists of tests which fail for shallow reasons such +as the syntactic differences, ``int`` vs ``long``, ``range()`` vs +``list(range())`` etc. As a result, the number of failing tests dropped_ from +650 to 235: we are beginning to see the light at the end of the tunnel :-) + +Finally, we did some RPython fixes, so that it is possible again to translate +PyPy in the py3k branch. However, the resuling binary is a strange beast which +mixes python 2 and python 3 semantics, so it is unusable for anything but +`showing friends how cool it's that`_. + +.. image:: py3k-activity-march.png + +I would like to underline that I was not alone in doing all this work. In +particular, a lot of people joined the PyPy sprint at Pycon and worked on the +branch, as you can clearly see in this activity graph. I would like to thank +all who helped! + +XXX: benjamin, could you write a quick summary of what you did? + +cheers, +Antonio + +.. _donated: http://morepypy.blogspot.com/2012/01/py3k-and-numpy-first-stage-thanks-to.html +.. _`py3k proposal`: http://pypy.org/py3donate.html +.. _`py3k branch`: https://bitbucket.org/pypy/pypy/src/py3k +.. _`showing friends how cool it's that`: http://paste.pocoo.org/show/577006/ +.. _dropped: http://buildbot.pypy.org/summary?category=linux32&branch=py3k&recentrev=53956:3c8ac35c653a _______________________________________________ pypy-commit mailing list pypy-commit@python.org http://mail.python.org/mailman/listinfo/pypy-commit
