Multimethods in Paper
by Niko Matsakis 17 Apr '09

17 Apr '09

This paper: http://portal.acm.org/citation.cfm?doid=1133651.1133655 describes MultiJava, which extends Java to support multi-methods and open classes. If I recall correctly, it contains a description of the different techniques they used and their performance characteristics. Might be useful for various OOType backends.... Niko

The JS backend had no active maintainer in a long time, so it wouldn't have matured. There just was no development on it. If you are interesting in taking over maintainership, please show up in the #pypy channel on freenode and get someone to give you commit privileges. Then we should probably discuss in which form it should be resurrected. Cheers, Carl Friedrich

Naming scheme
by Maciej Fijalkowski 16 Apr '09

16 Apr '09

Hello. That might sound a bit like bike sheding, but I would like to talk a bit about naming scheme. What do you think about actually naming PyPy release 2.5 after language version it supports? We can invent suffixes like pypy-2.5-something in order to release still 2.5, but which supports some more things (like JIT?). Cheers, fijal

LLVM and JS backends
by Carl Friedrich Bolz 16 Apr '09

16 Apr '09

Hi all, today we removed the LLVM and the JS backends from the trunk. Both were not really maintained anymore, there usefulness was limited and there tests were mostly skipped. The people at the sprint decided that it would be best to remove them from the repository so that they are not part of the release. If somebody is interested in reviving and actively maintaining them, please speak up. Cheers, Carl Friedrich

mentoring by proxy?
by inhahe 16 Apr '09

16 Apr '09

Hi, I overheard on the irc channel about 'mentoring', where someone who knows pypy acts as a mentor to bring someone else into deep knowledge of it, i'm assuming so they can work on pypy. i'm not asking for a personal mentor, because there's not a really big chance i'll be working on it, but i'm curious to know. so, i was wondering whether there's any archives/logs (maybe someone can upload me some if they're not on the 'net) of complete mentoring back-and-forths (or possibly tutorials) for me to go over. thanks.

PyPy issue tracker work?
by Alexandr N. Zamaraev 14 Apr '09

14 Apr '09

Hi PyPy-dev! :) Does it communicate the meaning of PyPy issue of the problems? I have created some issue (425, 433) and added to the patches 183 and 425. But there does not appear whether they are and in what condition. How can it get? -- Alexandr N. Zamaraev

Upcoming Sprint
by Niko Matsakis 07 Apr '09

07 Apr '09

Hello, Due to the enormous time demands on my PhD, I've been out of touch lately! I follow from the blog though :) and it seems like you guys have been doing great work. I am hoping to attend the sprint in Leysin. I would be able to come from the 14th until the 19th (I have to be back on the 20th, so I figure I'd leave 19th in the afternoon/evening). I'd have no problem sharing a room, though I'm not sure if the fact that I can't stay for the full sprint would be an issue. As for something to work on: besides hacking on whatever you guys think is important, I was considering porting one of my thesis ideas to Python. It has to do with an alternate means of specifying parallel programs (sort of a mix between threads and futures). Right now it exists in slightly different forms as both a Java and Python library (sorry, no web page), but I thought that by integrating it into the interpreter I might be able to do more, such as dynamic race detection. My concern is that because this is an experimental research topic, it doesn't really help with the goal of preparing the interpreter for general use. If it's not an appropriate topic for the sprint, then a compromise might be any tasks that would help me to learn about the interpreter so I can see better how to add my changes. Not sure if this mail ought to go to pypy-dev or pypy-sprint, so sorry if I chose the wrong one! regards, Niko

Hi friends, please have a look at this. http://code.google.com/p/unladen-swallow/wiki/ProjectPlan is this YAIPAP ? Yet Another Ignorant Python Acceleration Project I see them mentioning Hölzle and Self, and I see a reference to Psyco where they want to steal from, but PyPy does not exist. IMHO, this is totally GAGA - chris -- Christian Tismer :^) <mailto:tismer@stackless.com> tismerysoft GmbH : Have a break!

Re: [pypy-dev] did we submit any europython talks?
by Luke Kenneth Casson Leighton 06 Apr '09

06 Apr '09

i'll be at europython, to talk about the combination of http://pyjs.org and http://code.google.com/p/pyv8 which produces a really simple JIT python compiler. amongst other things. it'd be good to get an opportunity to speak with people, see where things stand, and where collaboration and cooperation would advance all these low-level python projects. l.

Cross implementation benchmarking and testing
by Michael Foord 06 Apr '09

06 Apr '09

Hello all, One of the things that came out of the Python language summit at PyCon was an agreement to improve the Python test suite for alternative implementations, plus attempt to develop useful cross-implementation benchmarks. Discussion of this is now happening on the stdlib-sig mailing list (which was chosen because it already existed and was unused): http://mail.python.org/mailman/listinfo/stdlib-sig Anyone interested can join the list. Michael -- http://www.ironpythoninaction.com/
