Hello; I cannot import csv via pypy Python Python 2.5.2 (pypy 1.0.0 build 60168) on linux2 Type "help", "copyright", "credits" or "license" for more information.

Some Newbie Questions
by Phyo Arkar 26 Nov '08

26 Nov '08

Hi Pypy Devs! I love python so much and I am so exicted by this ambitious project! What I understand about this Project is to develop a version of python , which is written in Pure Python . SO now , i do not have C Skills but I can Develop , Tweak , Make changes to python Just in Python , Am I Right? SO In Future , it is possible that Guido himself will be developing python in PyPy ? Question : I have to use Python Or RPython? Also By doing so , We can convert Python to Any langauge of Choice , which is very interesting. I have build pypy-c with optimization Level 3 and stackless , whcih is done flawlessly. I have seen benchmarks on one of the page and now PyPy is even faster then Normal python 2.5 827 vs 810 ms on Richard Test, it is very interesting . Question : Resulting pypy-c is python 2.4.1 , is there python 2.5 Version of pypy-c avaliable? I saw a branch about it before by a GSOC student but now is that already marged ?(my version svn is 4 days ago) If that arleady marged , how can i build it to get pypy-c with python 2.5 support? Another Questions is , If i follow my Python code in RPython , Can i converty RPythonic Code to C and compile ? SO it is possilbe to convert Existing Python Projects into C (if they follow Rpython)? If So , how can it be done ? An example , i will be very appreciate . Another , i compiled pypy-c in stackless , which is faster in term of pypy-c's perfomance? normal or stackless? If theres better performance options please let me know. Also doing , what are the extra modules added with --allworkingmodules ? I am hoping in near future , i can help in this project after enough understanding . Regards, Phyo.

sprint in Wrocław (PL)
by Bartosz SKOWRON 25 Nov '08

25 Nov '08

Hello folks! Fijal asked me to write about possibility of making a sprint in Wroclaw. There is a possibility to set a sprint at Wroclaw University of Technology campus for free. But we have a chance to reserve a class only during winter break. This period is between 30.01 - 22.02. I got a permission to make a sprint from uni's boss but i have to set the dates. My proposition is 9.02-15.02 2009. What about you? Are you interested in this sprint? The town is quite cheap (as whole Eastern Europe is) and there are a lot of hostels/hotels etc. Also it's very near to Germany and Czech Rep. Let me know if you have any questions. I should reserve a class asap but I need the dates and your opinion :) cheers! bart/getxsick

PyPy under FreeBSD 7
by Gabriel Lavoie 24 Nov '08

24 Nov '08

Hello, I'm trying to translate PyPy into pypy-c on FreeBSD 7.0 but at the beginning of the translation process I get the following error, NotImplementedError("don't know how to get the C-level errno!") from the file "pypy/rpython/lltypesystem/ll2ctypes.py". How can I solve this problem? It seems it's python-ctypes related. I'm using Python 2.5.3 (from ports tree) and when I tried to build the port "devel/py-ctypes", it told me that ctypes was provided with Python 2.5.x. Thanks!

PyPy Talks anyone got a copy?
by Timothy Baldridge 22 Nov '08

22 Nov '08

Hey, I'm trying to get a copy of the PyPy talks, but there doesn't seem to be anyone seeding the torrents. Does anyone have a HTTP copy I could download? If so I could host them on my HTTP server for others to download. Timothy -- Two wrights don't make a rong, they make an airplane. Or bicycles.

Else you will skip the test once we fix our own version number. ciao, Anto

compiler optimizations: collecting ideas
by Daniel Furrer 17 Nov '08

17 Nov '08

[This message has been posted to python-dev as well. Sorry for the duplication to those who read both.] Hello everybody, As part of an advanced compiler design course at our university (ETH Zurich), we have to implement an optimization (or various thereof). I've spoken with a couple of people who are, like me, very fascinated by Python. So I would just like to ask if somebody has any ideas on what we could do? Our constraints: - We are 4 persons, each willing to potentially spend around 4-6 full days of work. - We've been working on generating Control Flow Graphs, generating Static Single Assignment Form (inserting phi-nodes) and removing it again. We've also implemented techniques like constant folding, copy propagation, Common Subexpression Elimination etc. We're looking for: - Hints as to which python compiler would be best to work on. (The official Python compiler package seems very nice to work with actually... [and so does PyPy.]) - If there are any requests in the area of optimization that we could have a look at Any feedback would be highly appreciated as well as pointers to specific bugs in the tracker and other relevant discussions. Best regards, Daniel
