nightly builds and benchmarks page down
by Martijn Faassen 12 Dec '06

Hi there, I've noticed for a while now that the following page is down: http://snake.cs.uni-duesseldorf.de/pypytest/benchmark.html It's listed here: http://codespeak.net/pypy/dist/pypy/doc/index.html I thought I'd post a message here in case that this isn't deliberate. :) Regards, Martijn

RuPy conference
by Armin Rigo 10 Dec '06

10 Dec '06

Hi all, Should we try to get a PyPy talk at the upcoming RuPy conference in Poznan (Poland)? http://rupy.wmid.amu.edu.pl/ With luck it could trigger the start of a translation frontend for the restricted variant of Ruby that one of the Ruby-in-Ruby projects is based on, if we can convince people that this way leads to a full Ruby JIT :-) A bientot, Armin

Problem with subversion?
by Niko Matsakis 09 Dec '06

09 Dec '06

When I attempt to do a "svn up", I get the following error: ;svn up svnserve: error while loading shared libraries: libaprutil-0.so.0: cannot open shared object file: No such file or directory svn: Connection closed unexpectedly ; I get the error on multiple machines, both linux and OS/X, and I am able to work with other remote repositories, so I don't *think* it's my machine's fault...

problem with build tool
by Alexandre Fayolle 06 Dec '06

06 Dec '06

Hi, I will probably have no network access tomorrow, so I post this as a reminder, and also because the error takes time to reproduce. When finishing a build, the client process crashes with the following exception: <snip> [translation:info] created: ./pypy-c Traceback (most recent call last): File "bin/client", line 65, in ? zip.writestr(fpath.relto(udir), fpath.read()) File "/home/alf/dev/pypy/dist/py/path/common.py", line 312, in read f = self.open(mode) File "/home/alf/dev/pypy/dist/py/path/local/local.py", line 200, in open return self._callex(open, self.strpath, mode) File "/home/alf/dev/pypy/dist/py/path/common.py", line 229, in _callex raise cls, value py.error.ENOENT: [No such file or directory]: file('/tmp/usession-16/.lock', 'rb') Exception exceptions.AttributeError: "'ChannelWrapper' object has no attribute 'tell'" in <bound method ZipFile.__del__ of <zipfile.ZipFile instance at 0x2aaaac415fc8>> ignored The error is a bit mysterious to me, so if people in the assistance have an idea of what is happening but no time to fix it, their opinion is very welcome. -- Alexandre Fayolle LOGILAB, Paris (France) Formations Python, Zope, Plone, Debian: http://www.logilab.fr/formations Développement logiciel sur mesure: http://www.logilab.fr/services Informatique scientifique: http://www.logilab.fr/science Reprise et maintenance de sites CPS: http://www.migration-cms.com/

coroutine interface for CPython
by Stephan Diehl 05 Dec '06

05 Dec '06

Hi all, I've just hacked together a coroutine interface for CPython. Basicly, I've stripped out all references to pypy from christians interp_coroutine.py module. Amazingly, even pypy's stackless module works with this coroutine implementation. At the moment, all of this can be found here: https://codespeak.net/viewvc/user/stephan/hacks/coroutine/ Should I put this somewhere into the pypy repository? And if yes, where exactly? Cheers Stephan

Leysin sprint: 8-14th January 2007
by Armin Rigo 05 Dec '06

05 Dec '06

===================================================================== PyPy Leysin Winter Sports Sprint (8-14th January 2007) ===================================================================== .. image:: http://www.ermina.ch/002.JPG The next PyPy sprint will be in Leysin, Switzerland, for the fourth time. This sprint will be the final public sprint of our EU-funded period, and a kick-off for the final work on the upcoming PyPy 1.0 release (scheduled for mid-February). The sprint is the last chance for students looking for a "summer" job with PyPy this winter! If you have a proposal and would like to work with us in the mountains please send it in before 15th December to "pypy-tb at codespeak.net" and cross-read this page: http://codespeak.net/pypy/dist/pypy/doc/summer-of-pypy.html ------------------------------ Goals and topics of the sprint ------------------------------ * Like previous winter, the main side goal is to have fun in winter sports :-) We can take a couple of days off for ski; at this time of year, ski days end before 4pm, which still leaves plenty of time to recover (er, I mean hack). * Progress on the JIT compiler, which we are just starting to scale to the whole of PyPy. `[1]`_ * Polish the code and documentation of the py lib, and eventually release it. * Work on prototypes that use the new features that PyPy enables: distribution `[2]`_ (based on transparent proxying `[3]`_), security `[4]`_, persistence `[5]`_, etc. `[6]`_. .. _[1]: http://codespeak.net/pypy/dist/pypy/doc/jit.html .. _[2]: http://codespeak.net/svn/pypy/dist/pypy/lib/distributed/ .. _[3]: http://codespeak.net/pypy/dist/pypy/doc/proxy.html .. _[4]: http://codespeak.net/pypy/dist/pypy/doc/project-ideas.html#security .. _[5]: http://codespeak.net/pypy/dist/pypy/doc/project-ideas.html#persistence .. _[6]: http://codespeak.net/pypy/dist/pypy/doc/project-ideas.html ----------------------- Location & Accomodation ----------------------- Leysin, Switzerland, "same place as before". Let me refresh your memory: both the sprint venue and the lodging will be in a very spacious pair of chalets built specifically for bed & breakfast: http://www.ermina.ch/. The place has a baseline ADSL Internet connexion (600Kb) with wireless installed. You can of course arrange your own lodging anywhere (so long as you are in Leysin, you cannot be more than a 15 minute walk away from the sprint venue), but I definitely recommend lodging there too -- you won't find a better view anywhere else (though you probably won't get much worse ones easily, either :-) I made pre-reservations in the Chalet, so please *confirm* quickly that you are coming so that we can adjust the reservations as appropriate. The rate so far has been 60 CHF a night all included in 2-person rooms, with breakfast. There are larger rooms too (less expensive, possibly more available too) and the possibility to get a single room if you really want to. Please register by svn: http://codespeak.net/svn/pypy/extradoc/sprintinfo/leysin-winter-2007/people… or on the pypy-sprint mailing list if you do not yet have check-in rights: http://codespeak.net/mailman/listinfo/pypy-sprint You need a Swiss-to-(insert country here) power adapter. There will be some Swiss-to-EU adapters around - bring a EU-format power strip if you have one. ----------- Exact times ----------- Officially, 8th-14th January 2007. Both dates are flexible, you can arrive or leave earlier or later, though it is recommended to arrive on the 7th (if many people arrive on the 6th we need to check for accomodation availability first). We will give introductions and tutorials on the 8th, in the morning if everybody is there, or in the afternoon otherwise.

A new idea?
by Paul deGrandis 01 Dec '06

01 Dec '06

Hi everyone, I started to work on PyPy about a year to a year and a half ago, but had to quickly drop the project because of school and academic research I'm involved in. I really feel that even though PyPy is still at a stage of rapid development and evolution it's about time that people start really illustrating the true power of pypy. I'd like to be that guy for you. My idea is simple, I'll write small but useful applications that really illustrate the powers of pypy. These small applications can be loosely strung together as tutorials of language features or just examples of pypy's superiority. For some time now, I've developed small extensions to CPython in form of models, c extensions, and decorations to add features to the language that I find useful. However, Pypy's architecture naturally lends itself to these tweaks and in some cases supports them already. So basically, I want to know your thoughts on this. And if you have any ideas for applications or features you'd like to see illustrated please let me know! Regards, Paul
