[Stackless] Ann: PyPy Sprint before PYCON 2005 in Washington

[Christian Tismer]

Dear Stackless list members,

as you should know, PyPy will subsume, assimilate
and replace Stackless in just a few hundreds of
light years. Seriously, we are seriously working
on this. But please, this will take *much* longer
than you might estimate, so please support PyPy,
but at the same time support its surrogates, which
will be Psyco, Jython, Stackless and the general
py project on codespeak.net for a quite
reasonable amount of time :-)

PyPy is the next level of craziness, building upon
a solid basis of existing sourcery. Please don't forget
about this. You cannot support the one without supporting
the other.

Basically, this is all the same story! Just at a different
scale. Please try to come to the Washington sprint!

This introduction was written for the Stackless list,
only. The official announcement comes below:


PyPy Sprint before PYCON 2005 in Washington
-------------------------------------------

In the four days from 19th March till 22th March (inclusive)
the PyPy team will host a sprint on their new Python-in-Python
implementation.   The PyPy project was granted funding by the
European Union as part of its Sixth Framework Program,
and is now on track to produce a stackless Python-in-Python
Just-in-Time Compiler by December 2006.  Our Python
implementation, released under the MIT/BSD license, already
provides new levels of flexibility and extensibility at the
core interpreter and object implementation level.

Armin Rigo and Holger Krekel will also give talks about PyPy
and the separate  py.test tool (used to perform various kinds
of testing in PyPy) during the conference.

Naturally, we are eager to see how the other re-implementation
of Python, namely IronPython, is doing and to explore
collaboration possibilities.  Of course, that will depend on
the degree of openness that Microsoft wants to employ.

The Pycon2005 sprint is going to focus on reaching
compatibility with CPython (currently we target version 2.3.4)
for our PyPy version running on top of CPython. One goal of
the sprint is to pass 60% or more of the unmodified regression
tests of mainline CPython.  It will thus be a great way to get
to know CPython and PyPy better at the same time!  Other
possible work areas include:

- translation to C to get a first working lower-level representation
   of the interpreter "specified in Python"

- integrating and implementing a full parser/compiler chain
   written in Python maybe already targetting the new
   AST-branch of mainline CPython

- fixing various remaining issues that will come up while
   trying to reach the compatibility goal

- integrate or code pure python implementations of some Python modules
   currently written in C.

- whatever issues you come up with! (please tell us
   before hand so we can better plan introductions etc.pp.)

Besides core developers, Bea Düring will be present to help
improving and document our sprint and agile development
process.

We are going to give tutorials about PyPy's basic concepts and
provide help to newcomers usually by pairing them with
experienced pypythonistas. However, we kindly ask newcomers to
be present on the first day's morning (19th of March) of the
sprint to be able to get everyone a smooth start into the
sprint. So far most newcomers had few problems in getting a
good start into our codebase.  However, it is good to have the
following preparational points in mind:

- some experience with programming in the Python language and
   interest to dive deeper

- subscription to  pypy-dev and  pypy-sprint at

     http://codespeak.net/pypy/index.cgi?lists

- have a subversion-client, Pygame and graphviz installed on
   the machine you bring to the sprint.

- have a look at our current  documentation, especially the
   architecture and  getting-started documents under

     http://codespeak.net/pypy/index.cgi?doc

The pypy-dev and pypy-sprint lists are also the contact points
for raising questions and suggesting and discussing sprint
topics beforehand. We are on #pypy on irc.freenode.net most
of the time. Please don't hesitate to contact us or introduce
yourself and your interests!
