Re: rel 0.8 coord meeting, 2pm GMT+1 monday 31 Oct 2005 on #pypy

Hi Samuele, hi all,

There is one thing i see missing and i think it wasn't 
discussed at the release meeting: (more) documentation 
about the AST compiler.  This seems sensible especially
if the focus of the release is the AST compiler ... 

Adrien, Ludovic, do you already have something? 
ASFAIK we only have rough documentation on the Parser
(in parser.txt) but none on the compiler?!   Maybe we 
can take a bit from CPython and amend it to include
references to our file locations and some translation 
aspects/motivations for our changes?

also here i believe it should be explained what the main 
steps were to obtain the major speed improvements. 

cheers,

I think at least 8 or 10 people should be listed. 

Btw, I once had a different (half-manual) process of determining 
contributions by using "svn blame" and counting the lines. 
One has to be careful, though, because we have some large 
files (like the unicode-database) which are not really programmed 
code and distort the statistics. 

cheers,

I have updated the LICENSE file for 0.8 and copyright holders list


http://codespeak.net/pipermail/pypy-svn/2005-November/009556.html

this lists the copyright holders (we have a different list of 
contributor that contains all contributors, including people that just 
did small contributions or didn't want to be listed as copyright holders).

The additions are mostly people that were at the Paris sprint
and contributed there.

If people don't want to be listed please tell us so, as people did
in the past.

regards, Samuele Pedroni.

PyPy 0.8.0 just released

Thanks to all the people that contributed so far to PyPy and especially
to the people that helped on this release.

pypy-0.8.0: Translatable compiler/parser and some more speed
==============================================================

The PyPy development team has been busy working and we've now packaged
our latest improvements, completed work and new experiments as
version 0.8.0, our third public release.

The highlights of this third release of PyPy are:

- Translatable parser and AST compiler. PyPy now integrates its own
   compiler based on Python own 'compiler' package but with a number
   of fixes and code simplifications in order to get it translated
   with the rest of PyPy.  This makes using the translated pypy
   interactively much more pleasant, as compilation is considerably
   faster than in 0.7.0.

- Some Speed enhancements. Translated PyPy is now about 10 times
   faster than 0.7 but still 10-20 times slower than
   CPython on pystones and other benchmarks.  At the same time,
   language compliancy has been slightly increased compared to 0.7
   which had already reached major CPython compliancy goals.

- Some experimental features are now translateable.  Since 0.6.0, PyPy
   shipped with an experimental Object Space (the part of PyPy
   implementing Python object operations and manipulation) implementing
   lazily computed objects, the "Thunk" object space. With 0.8.0 this
   object space can also be translated preserving its feature

This Week in PyPy 1

(this summary is also on the web at 
http://codespeak.net/pypy/dist/pypy/doc/weekly/summary-2005-11-04.html)

Introduction
============

This is the first of what will hopefully be many summaries of what's
been going on in the world of PyPy in the last week.  First, I'd like
to make a request: help me write these things.  As is mentioned in the
page about This Week in PyPy:

    http://codespeak.net/pypy/dist/pypy/doc/weekly/

as and when something worth summarizing happens, be it on IRC, on a
mailing list or off in the blogosphere, add an entry to this file:

    http://codespeak.net/pypy/dist/pypy/doc/weekly/log

(if you can) or email me about it (if you can't).  This week noone at
all has done anything like this, which I'll forgive because it's the
first week :) Please, please do get into the habit of doing this
though, at least if you think writing this summary isn't a complete
waste of time.

Release of PyPy 0.8.0
=====================

The biggest thing that's happened in the past week was clearly the
release of PyPy 0.8.0.  You can read the release announcement at:

Document drafts

Hi all,

People following only this mailing list may have missed some draft
documents that we have been working on, as they are not linked to yet:

http://codespeak.net/pypy/dist/pypy/doc/draft-dynamic-language-translation.html
http://codespeak.net/pypy/dist/pypy/doc/draft-low-level-encapsulation.html

A bientot,

Armin

Feature-comparatives benchmarks

Hi all,

Even though it is short, I think that the draft-low-level-encapsulation
would look complete enough if it had, for each described aspect:

* a link to the doc (I'll add them);

* some concrete benchmarks, in an "Experimental results" section,
  to see what would be the performance/memory impact of enabling each
  feature or leaving it out of the compiled PyPy.

As far as I know our benchmark results are not nicely regrouped at some
place, so I suggest we collect them on this mailing list.  We need:

* Stacklessness: what are the most up-to-date results?

* Multiple Interpreters: I guess no one tried so far to compile in a
  mode where the 'space' variables don't go away.  Let's.

* Concurrency: not much data here apart from the massive unexplained
  overhead of enabling threads.

* Memory Management: refcounting is veeery slow, which only shows that
  we could do much better there given sufficient efforts...

* Evaluation Strategy: the thunk object space.  Overhead?

A bientot,

Armin.
