wrapping CPython objects
by Christian Tismer March 13, 2006

March 13, 2006

Hi friends, a quick question, maybe it is not so hard: I'm trying to wrap classes or instances which are built with RPython. I need to create a wrapper that is callable from CPyrthon. As I saw, there is already quite some support for wrapping arbitrary functions. What I'm probably missing is how the necessary conversions must be created for the rtyper. Or should I try to (ab)use rctypes for this? Probably overdone and also not easy since it's not ready? any hint would be very much … [View More]

Comparing PyPy with CLR
by Jiwon Seo March 12, 2006

March 12, 2006

Hi all, It was nice that I could meet some of you guys at the PyCon, and the sprint. I have a question related to PyPy's goal, etc; it might sound a little bit provocative, but that's not my intention at all. It's for me to explain other people the value of PyPy project. Anyway, I'll just shoot it :) Comparing PyPy to CLR, what is the strength of PyPy with respect to multi language support? CLR supports Common Type System and Common Intermediate Language, and with these CLR supports … [View More]

New code-templating system for py.lib
by Patrick Maupin March 12, 2006

March 12, 2006

I have been working on a new code templating system for py.lib. The initial documentation and the tokenizer are complete, and I am now working on the parser and the compiler. Please let me know if you have any feedback or questions. I have not yet made the documentation visible from the index.html file, but I have uploaded the doc file. You can view it at: http://codespeak.net/py/current/doc/code_template.html Thanks, Pat

Request for Review
by Gerald Klix March 12, 2006

March 12, 2006

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, can someone with more knowledge than me - I am thinking of Samuele and Armin here - look at pypy/dist/pypy/doc/ctypes-integration.txt and tell me and the other ctypes workers, wether the pointer representation is translateable? Currently I am running into problems when I want to translate a function that returns a pointer to a strcuture. Michael gave a hint, telling me that returning a pointer won't work with the test wrapper., but if I change … [View More]

Leysin sprint: need exact dates
by Christian Tismer March 12, 2006

March 12, 2006

Hi friends, I would like to ask you about the exact dates for the internal Leysin sprint. My plan was to come back from USA at March 30, but since my flight is going through Switzerland, anyway, it might make much more sense to go directly there. I would like to reschedule my flights and ask for confirmation if we are sprinting from April 3 to 9, exactly? many thanks - chris -- Christian Tismer :^) <mailto:tismer@stackless.com> tismerysoft GmbH : Have a … [View More]

Looking for a thesis
by Antonio Cuni March 11, 2006

March 11, 2006

Hi, my name is Antonio and I'm studying computer science at university of Genoa (Italy). Since I need a thesis for graduating and since I love Python very much I'd like to contribute to the pypy project, if you think I could help. I have already read the online docs and I have played a little with the current version of pypy. I have two questions: 1) do you think I could help the project, as I hope? 2) what tasks do you think could be suitable for a thesis? Obviously before begin coding I … [View More]

The thesis should take 3-4 months, thought I hope to continue with the project after I've completed it, … [View More]

framework gcs and NULL termination
by Michael Hudson March 10, 2006

March 10, 2006

So earlier on today I built the first pypy-c using for its memory management one of the frameworks written by Carl last summer, which I think is pretty cool! After one more bugfix, it seems reasonably solid, running at least a few of CPython's regression tests fine, if a little slowly for now. However, all is not perfect. The build occasionally dies with a random (PyPy level) OSError and string formatting with floats doesn't quite work right: >>>> "%f"%1.0 '1.000000\x11' I … [View More]

Bad bug, exposed to Raymond :-()
by Christian Tismer March 10, 2006

March 10, 2006

[rewriting waht I wrote into the issue tracker, which for some reason didn't get it -- broken? ] Hi friends, it happened that I was sitting here with Raymond Hettinger, and we played a bit with a code example that Gromit posted on the PyPy IRC channel the other day. The examples were (1) map(apply, [lambda: t for t in range(10)]) (2) map(apply, (lambda: t for t in range(10))) The expected results are [9]*10 for (1). We were not so sure what (2) should give, so I felt inclined to say … [View More]
