expected_extra_mallocs
by Simon Burton July 20, 2007

July 20, 2007

Here is a little test: def func(): x = 1. print x def test_1(): from pypy.translator.c.test.test_genc import compile _func = compile(func, []) _func() I get this error: _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ def checking_fn(*args, **kwds): if 'expected_extra_mallocs' in kwds: expected_extra_mallocs = kwds.pop('expected_extra_mallocs') else: expected_extra_mallocs = 0 res = compiled_fn(*args, **kwds) … [View More]

Sprint report
by Jacob Hallén July 18, 2007

July 18, 2007

I think this got stuck in moderation, as I sent it with a from address that didn't match my mailinglist subscription. Justas, Arlo Belshee and I worked on Python 2.5 compliance. We started with the "with" statement and fairly quickly found that it seemed to work as intended, except for the fact that the necessary "from __future__ import with_statement" had no effect. To make this work properly, we decided to make a clean implementation - CPython does nasty things in order to avoid … [View More]

More sprint reporting
by Jacob Hallén July 17, 2007

July 17, 2007

Here is what I know happened in other groups: Armin and Laura worked on rffi. After 2 days of trying different approaches and getting stumped each time, they made a breakthrough on Saturday, and managed to produce a fairly complete slution in a matter of a few hours. Making the solution more complete would require a rewrite of ctypes (Ick!). Maciek worked on getting PyPy to be self hosting under pypy-c. This succeeded before he left the sprint. Jakub worked on more scheme features. With … [View More]

revision 45089
by Simon Burton July 17, 2007

July 17, 2007

I found that revision 45089 makes compilation much slower. No idea why. Simon. ------------------------------------------------------------------------ r45089 | justas | 2007-07-14 08:35:59 -0700 (Sat, 14 Jul 2007) | 8 lines (Arlo, Justas) Introduce --pyversion option to select the parser/compiler grammar Defaults to 2.4, also accepts 2.3 and 2.5a. Changed a bunch of imports to use the selected grammar. TODO: pypy/interpreter/pyparser/symbol.py uses a fixed list of symbols, and it shouldn't

Taking pypy for a test drive
by Greg Bowyer July 13, 2007

July 13, 2007

Sorry if this is an exceptional newbie post ... Now that pypy has hit v1 I have tried using it for a few test examples, most of this stuff so far is a little bit simple, however one test is to run a django application that I am developing for someone with pypy rather that cpython However when I fire up pypy i get the following from the django application, what am I missing here greg@gregslaptop ~/projects/minesite/minesite $ ./pypy-c manage.py runserver debug: WARNING: library path not … [View More]

Win32 tester
by Scott Dial July 13, 2007

July 13, 2007

Greetings Everyone, I am going to have to stop running the win32 test suite. I am not sure there is anyone actively correcting problems on win32, so it may be of no consequence. If someone else is interested in running this, then I would be more than glad to share my knowledge with them. Otherwise, sorry to leave you without. -Scott -- Scott Dial scott(a)scottdial.com scodial(a)cs.indiana.edu

Quick personal view regarding js interpreter
by Maciek Fijalkowski July 11, 2007

July 11, 2007

It's completely unusable. Usually you end up with Fatal RPythonError in case you try to run stuff. This is not how we go about stuff! All error reporting should work well not only on top of js_interactive, but actually on top of js-c as well. Leonardo - have you even run js_interactive once before you commit? Last time it was unbound local or so. Cheers, fijal :.

paper on runtime specialization
by Carl Friedrich Bolz July 9, 2007

July 9, 2007

Hi all! Today I found this rather interesting paper on runtime specialization of C: http://www.cs.washington.edu/research/dyncomp/Papers/tr-97-03-03-abstract.h… I have only skimmed it so far, but it seems there are many shared ideas between PyPy and this approach. Cheers, Carl Friedrich

select/test_readable on Win32 blocks forever
by Scott Dial July 5, 2007

July 5, 2007

Greetings, I haven't figured this one out. As the subject says, test_readable for the select module gets stuck forever. If I trust the history of the bot, then it appeared somewhere after r44639 and before r44646. I've looked through the revisions and nothing jumped out at me.. happy hunting to someone more aware of the changes. -Scott -- Scott Dial scott(a)scottdial.com scodial(a)cs.indiana.edu
