stmgc: rethinking the GC?
by Armin Rigo 22 Dec '15

22 Dec '15

Hi Remi, Just thinking about stmgc: currently it requires large transactions in order to work efficiently. I think it is mostly caused by the fact that transaction commits always force a minor collection. Maybe we should rethink that at some point, by changing the GC completely... There are moving GCs that are really concurrent but they tend to be an advanced mess. Maybe a better alternative would be to experiment again with non-moving GCs. Non-moving generational GCs are not very common as far as I know, but they do exist; for example see http://wiki.luajit.org/New-Garbage-Collector . A bientôt, Armin.

Running Tests for the py3.3 branch

I know I've asked this in irc at least 5 times at this point, but I am still running into issues when I try to run the tests. I have built a pypy binary locally. My exact steps: hg update default cd pypy/goal pypy ../../rpython/bin/rpython --opt=2 #Wait for it to finish... cd .. cd ..

(A couple have actually failed the same as they have failed for the py3.3 buildbot, but every still-failing test that I have specifically run passes locally now, so something must be wrong.) Why is there a difference in behavior between my /usr/bin/pypy and my newly-built pypy? Why are neither of the pytest.py commands matching the output of the tests run by the buildbot? I don't really understand how lib_pypy is supposed to interact with the python used to invoke the tests. The behavior seen when I run the tests with my pypy-c makes sense to me, failing as soon as it runs into python3-specific code. I don't really get why the tests don't fail the same way when I run the tests using the "pypy" executable. If anyone could explain where I have gone wrong, it would be greatly, greatly appreciated. Thanks

AppTestCpythonExtention tests
by Matti Picus 07 Dec '15

07 Dec '15

in cpyext there are AppTestCpythonExtension tests, which compile a small capi module and then test it. It seems like there should be a way to run these tests with the -A flag, which would allow testing in cpython and on translated pypy Before I embark on this journey, has it been tried before and if so what were the conclusions?

Hello, in 81104:6a35beb87a56, I see that the now merged branch fix-setslice-can-resize was not described properly and now the what's new document does not contain any description. Is there something to do to fix this ? What should I have done before asking the PR ? Thanks -- Vincent Legoll

Issue intalling Numpy module
by PASCAL DIAFERIA 01 Dec '15

01 Dec '15

NARBONNE, 12/01/2015 Hi, I want to use Pypy ; I'm trying to install Numpy ; to that, I launched the next command: git clone https://bitbucket.org/pypy/numpy.git then in in Numpy directory, I launch the next command : pypy setup.py install I get the next error : ============================================ Traceback (most recent call last): File "setup.py", line 278, in <module> setup_package() File "setup.py", line 261, in setup_package import setuptools ImportError: No module named setuptools ============================================ [Os = Win7 / 64-bits ; Python2.7.10] Pypy installed, pip, ... installed Maybe, you know the mean to bypass this step ; I have to say I'm not experienced and I'm looking for help to solve this problem. So, if you have any suggestion I will take and try it. In advance, thanks a lot (do not care of my written english as it's not my mother language).
