David Malcolm Mon Jan 3 23:13:38 CET 2011 > I've packaged pypy in RPM form for the Fedora distribution and RPMs are available @, e.g., http://rpm.pbone.net/index.php3/stat/4/idpl/15770592/dir/rawhide/com/pypy-1… Shouldn't this be linked to, or at least mentioned, on http://pypy.org/download.html ?

Re: [pypy-dev] [pypy-commit] pypy default: don't raise a warning if the restype is not set, and add a test to check that we hit the fastpath even in that case

> > Log: don't raise a warning if the restype is not set, and add a test to > check that we hit the fastpath even in that case Uh, can we revert this? I think a runtime warning when restype is not set is an excellent idea from the correctness perspective.

Bitbucket offering to donate servers, hosting ...
by Laura Creighton July 25, 2011

July 25, 2011

This showed up on the infrastructure mailing list. I'd like a really nice windows machine always available for benchmarking and another one to test on. What would other people like? Make a list and we can ask Charles McLaughlin if the offer is still open. As far as I know the OSU/OSL hosting is linux only.

Benchmarks
by Maciej Fijalkowski July 24, 2011

July 24, 2011

Hi I'm a bit worried with our current benchmarks state. We have around 4 benchmarks that had reasonable slowdowns recently and we keep putting new features that speed up other things. How can we even say we have actually fixed the original issue? Can we have a policy of not merging new performance features before having a story why benchmarks got slower? Current list: http://speed.pypy.org/timeline/?exe=1&base=none&ben=spectral-norm&env=tanni… http://speed.pypy.org/timeline/?… [View More]

binascii.crc32() OverflowError?

July 23, 2011

Hello all. I'm getting an OverflowError error only when I run my program in pypy. I've simplified it to a couple of lines: binasciiproblem.py: import binascii value = 0 new_value = 'a' value = binascii.crc32(new_value, value) & 0xffffffff value = binascii.crc32(new_value, value) & 0xffffffff Python 2.7.1: runs without problems.

PyPy is much slower than CPython example / question
by Alexander Petrov July 20, 2011

July 20, 2011

Hi. I'm new to PyPy and was trying to run some tests to see orders of speed improvement. Short script generating list of prime numbers using rather straightforward implementation of Eratosthene's sieve. Script: http://paste.pocoo.org/show/432727/ Typical results: http://paste.pocoo.org/show/432733/ (I thought that is due to absense of SSE2 on first computer, but I've rechecked on Intel(R) Xeon(R) CPU L5520 @ 2.27GHz with similar results). I'm getting that CPython is nearly 4-8 times faster … [View More]

win64
by Armin Rigo July 18, 2011

July 18, 2011

Hi Christian, A quick poll about the 'win64 test' branch. Is it going fine? If ll2ctypes is continuing to give you troubles, I'd suggest to move on; keep in mind that ll2ctypes is only used for testing. I would recommend that your priority should be to pass the tests in pypy/rpython/test/ and pypy/translator/c/test/, and when it is done, move on to pypy/rlib/test/ and pypy/module/*/test/. A bientôt, Armin.
