llinterp trace
by Armin Rigo 29 Apr '06

29 Apr '06

Hi all, As a quick hack I made llinterp produce traces of all operations it executes -- no longer to stdout or py.log, but to an html file written to /tmp/usession-*. It's a hierarchical-looking page showing the nested calls. With Javascript browsers we can hide and show sub-calls by clicking around; all calls are initially hidden. It's certainly a more useful presentation than the terminal-based one. Of course I'm open to further suggestions :-) A bientot, Armin.

How a SoC (2 months longer) task can be? I'd like to apply for this kind of project but I'd like to know more about it too. We can discuss about 5, or 10 or so modules that PyPy needs? Or it's up to the student to choose them? Thanks in advance. -- Lawrence http://www.oluyede.org/blog

PyPy is flooding Genova :-)
by Antonio Cuni 28 Apr '06

28 Apr '06

Hi all, as the subject suggests, people seems to get interested in PyPy here at Genova's university, due to my thesis :-). As a consequence next week I'll probably have a talk for introducing some interested people to PyPy. Since there is a number of introductory presentations I was thinking of using one of those instead of writing yet another one; the more updated seems to be the accu2006 one, right? I've noticed that it has been written with Keynote: can someone send it me in a format I can open with OpenOffice or PowerPoint, so that I can add some slides specific to the CLI backend, please? Moreover my supervising professor is considering the possibility to establish a more actual collaboration between my university and the PyPy project, so he would be glad to speak with someone of the core team about this. ciao Anto

difference between py.py and pypy-c
by Stephan Diehl 28 Apr '06

28 Apr '06

Hallo, I found another difference in bahaviour between py.py and pypy-c with my set implementation enabled. The 'ior' operator in pypy-c does not behave as expected. My first thought was, that somehow the rdict.update method does not work as expected, but translator/goal/targetrdicttest2.py behaves, as it should, so there goes that theory. I have no idea whatsoever, where to look next.

Summer of code
by Antonio Cuni 27 Apr '06

27 Apr '06

Hi all, I'm considering the possibility of applying to Google Summer of Code 2006: obviously the topic of my application would be pypy :-). As you can guess I'd like to continue working on the CLI backend, also considering that I probably won't be able to finish it before I graduate. The point is that by now I can't know how mature gencli will be when soc starts, so it's difficult to write a good proposal: how can I say where I'll arrive to if I don't know where I have to start from? I could submit a vague proposal, but I guess that something like "working on the CLI backend" is a bit too elusive for being accepted. Any suggestions? ciao Anto

Last Tuesday we decided to discuss this more on an IRC meeting, with Christian, Michael, Samuele and myself, plus of course any other interested people. Christian, can you check in the extra details you promized? I wanted to make sure we would discuss this on the basis of previously-written details. I'll anyway propose that we meet tomorrow Friday, again at 5pm CET. A bientot, Armin

Question on snake server test runs
by Sanghyeon Seo 26 Apr '06

26 Apr '06

http://snake.cs.uni-duesseldorf.de/pypytest/summary.html I added a py.test option to pretty-print Common Lisp source files, and tests on snake server started to fail. Samuele told me that it might depend on the working directory from which py.test is run, but no matter how I try, I couldn't reproduce the failure in my machine. So my question is: how are tests run on snake server? How can I fix this failure? E if conftest.option.prettyprint: > AttributeError: Values instance has no attribute 'prettyprint' Seo Sanghyeon
