Print unicode strings in RPython?
by Ryan Gonzalez Nov. 27, 2013

Nov. 27, 2013

Hello, I'm writing an app in RPython. Whenever I try and print a unicode string, the compiled application will crash with a UnicodeEncodingError. Here is an example: def entry_point(argv): print u'\u2502' return 0 def target(driver, args): return entry_point, None When running it, I get this: RPython traceback: File "implement.c", line 164, in entry_point File "rpython_rtyper_lltypesystem_rstr.c", line 190, in ll_str__UnicodeR_Ptr_GcStruct_rpy_unic_rpy_unico Fatal RPython … [View More]

some stm links
by Carl Friedrich Bolz Nov. 27, 2013

Nov. 27, 2013

Hi all, during OOPSLA I came upon some papers/projects that may be relevant to the STM effort, that I found interesting (though I haven't read them in detail yet, just skimmed). IBM Research Japan is doing a project to try to eliminate the GIL of Ruby's C VM using HTM extensions of various processors (mostly IBM stuff, I think): http://researcher.watson.ibm.com/researcher/view_person_subpage.php?id=4800 CDSChecker is a model checker for concurrent C/C++ code that claims to put a lot of … [View More]

PyArray_Type cpyext bug
by Antonio Cuni Nov. 25, 2013

Nov. 25, 2013

Hi, I committed a cpyext+numpy failing test in a3c3b75a7f2b. In short, the following fails: if (!PyArg_ParseTuple(args, "O!", &PyArray_Type, &obj)) return NULL; The problem is that PyArray_Type is currently defined in ndarrayobject.c but never initialized: PyTypeObject PyArray_Type; not a suprise that we get a segfault when we try to use it. However, I'm not sure about what is the best way to fix it, so I ask the cpyext wizards :) I think that at the end what … [View More]

pytest and numpypy status
by Matti Picus Nov. 25, 2013

Nov. 25, 2013

Currently we are running tests via nose for the pypy-compat fork of numpy under pypyin a nightly buildbot task. I have changed the test runner to pytest in a branch of the buildbot, and it runs and creates a summary page, but I fear the page with ~2000 failures will create too much of a load on the buildbot. I tried to sort the failures by frequency here http://bpaste.net/show/152720/ , this counts how many times each "E <errortxt>" appears in the log file. The biggest stumbling … [View More]

Doing a 2.2.1 release
by Alex Gaynor Nov. 24, 2013

Nov. 24, 2013

Hey all, In the 2.2 release we just did, there's a bug in ssl/socket which makes simple things like requests.get("https://pypi.python.org") with the requests module fail. I've landed a fix in 963c6d6d7d6c. What do people think about doing a release?

pypy's INSTALL_SCHEME
by Michal Vyskocil Nov. 20, 2013

Nov. 20, 2013

Hi, I found pypy's behavior of pypy setup.py install --prefix=/usr quite surprising as it installs all files to /usr/site-packages, which is not the most expected location. But distutils/commands/install.py says so 'pypy': { 'purelib': '$base/site-packages', 'platlib': '$base/site-packages', 'headers': '$base/include', 'scripts': '$base/bin', 'data' : '$base', }, which does not makes a sense to me as /usr/site-packages is not in default sys.path $ pypy -c "import sys; … [View More]

by Armin Rigo Nov. 18, 2013

Nov. 18, 2013

Hi all, Here's the release candidate for PyPy 2.2.1 on Windows: it fixes the json decoding, and adds Tk support (thanks Matti!). Please tell me if there is some problem with it. http://buildbot.pypy.org/nightly/release-2.2.x/pypy-c-jit-68207-1567dba349e… On other platforms, PyPy 2.2.1 will not be released, as nothing changed. A bientôt, Armin.

More strategies
by Laurence Tratt Nov. 16, 2013

Nov. 16, 2013

I've been fiddling with extending some of the strategies in PyPy. My first port of call has been to provide fast paths in IntegerListStrategy.find, which is the basis of "x in l" and "l.index(x)". Previously this was very fast if you looked up an integer, but rather slow if you tried up looking anything else. Since we know exactly what the type of every element in such a list is, there seem to be quite a few opportunities for optimisation. I have left the code for the common case (looking up an … [View More]
