Poor performance for Krakatau
by Robert Grosse Aug. 10, 2015

Aug. 10, 2015

In some cases, Pypy performs worse than CPython when running Krakatau, and it has gotten a lot worse from 2.3 to 2.5 My benchmark is https://github.com/Storyyeller/Krakatau/tree/pypy_benchmark (for future reference, commit d889c7f44723e6d66a3630681f0385f173317dc9) You can run it with pypy Krakatau\benchmark.py -path <path to Java rt.jar> I get the following timings CPython: 17.43s Pypy 2.3: 38.48s (build pypy-c-jit-71056-c8e3b8cbc843-win32) Pypy 2.4: 39.92s (build pypy-c-jit-72200-… [View More]

serialize and deserialize objects in Pypy
by Yicong Huang Aug. 7, 2015

Aug. 7, 2015

Hi, Are there any good methods to serialize Pypy object to C++ char* and deserialize to Pypy object from C++ char*? Our scenario like this: We have at least two C++ process running, and each process embeded Pypy to execute some functions. And we woule like to reuse Pypy object from one process to another process. For primitive objects, int/char/bool/double etc., we could use cffi to pass objects. Pypy object -> c++ process 1 -> c++ process 2 -> Pypy object But for complex objects, … [View More]

Running pypy unit tests
by Vaibhav Sood Aug. 6, 2015

Aug. 6, 2015

Hi All, I work on Python through which I came across pypy and I am interested in making some open-source contributions to the project. As first steps I tried building the source code (successfully) and running the unit tests as per the "Getting Started Developing with PyPy" page but I run into an issue The way I run the tests is "./pytest.py <folder>" for each folder in the source code, I get the test results all folders but the command hangs for one particular folder "pypy/module" For … [View More]

Hi Brecht We tried the strbuf with rinohtype and (after warmup) it's the speed of cpython, which is bad. investigating some more....

Building on case-insensitive file system
by Cyrus Daboo Aug. 5, 2015

Aug. 5, 2015

Hi, OS X defaults to having a case-insensitive file system. I believe there is a problem with building pypy from source on such a system. During the build process I see files being written to the jitcodes directory in the /tmp build directory. There are some "W_ArrayTypeX.*" files being written there, where "X" is a typecode (which I believe comes from pypy/module/array/interp_array.py). The allowable codes come from the set "c, b, B, u, h, H, i, I, l, L, f or d". Note that there are a … [View More]

For Donations, List How Much is Left (or Spent)?
by Donald Stufft Aug. 3, 2015

Aug. 3, 2015

Hey! So out of someone complaining about PyPy's lack of an up to date port of Python 3, it struck me that for someone just now looking into PyPy it looks like PyPy is sitting on almost 60k USD in order to port PyPy3 from 3.2 to 3.4. However the reality (via fijall) is that most of it, roughly 50k has already been spent going from nothing to 3.2. It might be a good idea to have the numbers reflect how much of the fundraised money has already been spent so that people get a more accurate … [View More]

pypy-2.3.1 memory profiling strategies
by jim horng Aug. 3, 2015

Aug. 3, 2015

Hi all, Not sure if it's appropriate to post here since there's no pypy-user group :) My question is as title, we got memory leak on pypy process and process will down when out of memory, only on production site. Our simplified environment as below: * OS: Centos 6 * pypy-2.3.1 objgraph is seems the only profiling library we can use in this env, and only with its partial function of printing all current objects in memory instead of any further info such as references (.getrefcount not … [View More]

Best way to use py.test with RPython projects and travis-ci?
by Sarah Mount Aug. 3, 2015

Aug. 3, 2015

This week someone pushed a nice commit to a Python repository I contribute to, which sped up Travis builds by upgrading pip and using the cache to store requirements. I thought "that's neat, I should try that trick in my own (R)Python projects". And that, friends, is how I entered a whole new world of pain and suffering. It seems that if you install py.test using pip and cache pip packages in Travis, like this: https://travis-ci.org/futurecore/revelation/builds/73584887 I think because PyPy … [View More]
