Py3k status update #8

This is the eight status update about our work on the py3k branch, which
we can work on thanks to all of the people who donated to the py3k

Just a short update on November's work: we're now passing about 194 of
approximately 355 modules of CPython's regression test suite, up from passing
160 last month. Many test modules only fail a small number of individual tests

We'd like to thank Amaury Forgeot d'Arc for his contributions, in particular he
has made significant progress on updating CPyExt for Python 3 this month.

Some other highlights:

  • test_marshal now passes, and there's been significant progress on
    pickling (thanks Kenny Levinsen and Amaury for implementing
  • We now have a _posixsubprocess module
  • More encoding related fixes, which affects many failing tests
  • _sre was updated and now test_re almost passes
  • Exception behavior is almost complete per the Python 3 specs, what's mostly
    missing now are the new __context__ and __traceback__ attributes (PEP
  • Fixed some crashes and deadlocks occurring during the regression tests
  • We merged the unicode-strategies branch both to default and to py3k: now we
    have versions of lists, dictionaries and sets specialized for unicode
    elements, as we already had for strings.
  • However, for string-specialized containers are still faster in some cases
    because there are shortcuts which have not been implemented for unicode yet
    (e.g., constructing a set of strings from a list of strings). The plan is to
    completely kill the shortcuts and improve the JIT to produce the fast
    version automatically for both the string and unicode versions, to have a
    more maintainable codebase without sacrificing the speed. The autoreds
    branch (already merged) was a first step in this direction.

Well done. PyPy is one the most interesting projects out there today.
Keep up the amazing work guys!
