use as benchmark pypy vs python if you please
by Dima Tisnek 13 Sep '15

13 Sep '15

Attached is n-queens solver (pardon my naive algorithm), it runs: python 2.7.6: 17s pypy 2.4.0 alpha: 23s same nojit: 32s I've tried similar-looking algorithm for another problem before, and has similar results -- somehow pypy was slower. feel free to investigate / tweak or even use on speed.pypy.org

Segmentation fault at rpyvmprof_f_pypy_rrr ()
by Yicong Huang 08 Sep '15

08 Sep '15

Hi, We observed the program was cored dump. And examing the core file, we found the call stack: #0 0x00007f26487e6b82 in rpyvmprof_f_pypy_rrr () from /usr/local/pypy/libpypy-c.so #1 0x00007f26494a797a in rpyvmprof_t_pypy_rrr () from /usr/local/pypy/libpypy-c.so #2 0x00007f26487a1ad4 in pypy_g_appexec___src__glob___________________import_sys () from /usr/local/pypy/libpypy-c.so #3 0x00007f26486f980b in pypy_g.pypy_execute_source () from /usr/local/pypy/libpypy-c.so #4 0x00007f26486f9994 in pypy_g_pypy_execute_source_ptr () from /usr/local/pypy/libpypy-c.so #5 0x00007f26484e6f42 in pypy_execute_source_ptr () from /usr/local/pypy/libpypy-c.so #6 0x00007f26484e6d82 in pypy_execute_source () from /usr/local/pypy/libpypy-c.so ... And debugging the core file, the char* buffer passed to pypy_execute_source() was: (gdb) print pyExBuffer $1 = "import sys\nsys.path.insert(0,'job_runtime/lib/python2.7/site-packages/udf')\000/1440989742122"... The code was to add a directory to sys.path(). The error was not reproduceable by extracting the piece of code from the whole programme, and I've no ideas why the segmentation fault happened. Does anyone knows what the function "rpyvmprof_f_pypy_rrr ()" did? And are there any methods to debug and found out the cause?

2.6.1 and freebsd-9
by Matti Picus 01 Sep '15

01 Sep '15

I would like to add the freebsd-9-x86-64 binary tgz to our released downloads. We still have a number of failing tests showing up on http://buildbot.pypy.org/summary?category=freebsd64 among them many DLOpenError: "opening 'libm.so' with ctypes.CDLL() works, but not with c_dlopen()??" and the more worrying SIGSEGV in http://buildbot.pypy.org/summary/longrepr?testname=unmodified&builder=pypy-… Could someone proficient in freebsd suggest what is going on?

Dependencies in noon-standard locations
by Skip Montanaro 01 Sep '15

01 Sep '15

I've encountered a problem building the 2.6.1 distribution from source: [translation:ERROR] /tmp/usession-release-2.6.1-0/platcheck_54.c:79:19: error: expat.h: No such file or directory I don't remember encountering this before, but most of my earlier builds were probably on Mac OS X. My guess is the error results from a non-standard expat location: % find /opt/TWWfsw/ -name 'expat.h' /opt/TWWfsw/libexpat20/include/expat.h I saw nothing about how to deal with this in the instructions. Searching the source, I saw no instances of things like LDFLAGS or CPPFLAGS which I'm used to using in other build environments. How do I specify these oddball locations to PyPy? I'm using OpenSuSE 12.2, which I doubt will work with any of the PyPy binaries. Would love to be proved incorrect though. Thx, Skip Montanaro

avoid pypy's csv module
by Arno Waschk 31 Aug '15

31 Aug '15

dear list, i have a problem with pypy's csv module. Apart from it being somewhat slower than cPython's (i could live with that) i am getting rarely but annoyingly corrupted files written, which have some single corrupted lines. I cannot provide enough information (yet) for debugging, it looks like a writing race condition, although i am 120% sure that my program does never more than one writing event at any moment. Everything worked fine in cpython (for years), so my question is, can i simply tell pypy to run my program, but use CPython's implementation of the csv module? thanks, Arno -- Arno Waschk arno(a)arnowaschk.de +491723149605 +436508950949 (nur während Projekten in Österreich) current and upcoming projects: Wien Burgtheater Goethe: *Faust I* (Repertoire) Matthias Hartmann Berlin Staatsoper im Schillertheater Satie: Le Piège de Méduse --- *Satiesfactionen: Wissen Sie wie man Töne reinigt?* (Repertoire) Jürgen Flimm Neuhardenberg/Leipzig u. a. *Lesungen mit Klaus Maria Brandauer* *Via intolleranza II* Christoph Schlingensief Wien Burgtheater *Mea Culpa* (Repertoire) Christoph Schlingensief Berlin Staatsoper im Schillertheater Maxwell Davies & Sciarrino: *Miss Donnithorne's Maggot // Infinito Nero (Repertoire)* Staatskapelle Berlin Michael von zur Mühlen *franz.

type inference error
by Andrey Ayupov 27 Aug '15

27 Aug '15

Hello, Hopefully a very simple question. I am trying out RPython toolchain. pypy 2.6, python 2.7. I am using the translator shell. Here's my simple example: python bin/translatorshell.py class mtype(): def __init__(self): self.x = 0; def mmm(x): z = x.x + 1 return z t = Translation(mmm, [mtype]) t.annotate() and it gives me the following. if you put mtype class and mmm function definitions in a separate module, then you can see it complains about this line: z = x.x + 1. Why can't it infer type for all arguments and the result here? I know i am missing something basic.

[newb] Regarding pull requests
by Vaibhav Sood 26 Aug '15

26 Aug '15

Hi, I had submitted a pull request earlier (https://bitbucket.org/pypy/pypy/pull-requests/331/fix-test-case-for-py33-br…) for a nightly test case fix on the py3.3 branch. I haven't received any reviews, just wanted to check regarding the same, I apologize if this is not the right way to prod but thought I'll ask I also had a query regarding submitting pull requests (this is my first time submitting one), do I need to specify somebody as a reviewer when creating the PR? Or do I just submit and wait for a review? Thanks you!

[newb] fixing a nightly test case failure
by Vaibhav Sood 21 Aug '15

21 Aug '15

Hi, I am a newbie to pypy and looking to start making some contributions to the project. I was looking at the buildbot test case failures (after referring to an earlier thread on this forum: https://mail.python.org/pipermail/pypy-dev/2015-July/013751.html ) for the py3.3 branch and to start off picked a test failure to work on: http://buildbot.pypy.org/summary/longrepr?testname=AppTestFunction.%28%29.t… I was looking for some guidance as to the steps to make a code change contribution. I checked the bug tracking list but didn't find this test failure listed, would the typical steps be to create a issue in bug tracking system first, work on the change and then submit the patch for commit? My concern is I want to verify I can work on this failure and that I am not duplicating or doing unnecessary work Thanks, Vaibhav DISCLAIMER ========== This e-mail may contain privileged and confidential information which is the property of Persistent Systems Ltd.
