Working version of pypy3 that support Python 3.3
by Ram Rachum 14 Jun '15

14 Jun '15

Hi everyone, I want to test my PyPI package on pypy3, but my package only support Python 3.3 and above. I know that a version of pypy3 that support Python 3.3 is not ready yet, but is there a development version of it that I can run so I could test my package and find any bugs in it? (And possibly also bugs in pypy.) Thanks, Ram.

Freezing the ".pypy-26.so" name?
by Armin Rigo 14 Jun '15

14 Jun '15

Hi all, The cpyext and cffi extension modules are created with the extension ".pypy-XY.so", were X and Y are the current PyPy version. I believe that there is little point any more: as far as I'm aware, nothing in the API changed since a long time, and all these different versions are identical to each other. Should we simply freeze the ".pypy-26.so" name, so that future PyPy's will also use it, at least until some really incompatible change is made? This would resolve for example issues like https://github.com/pypa/pip/issues/2882 . A bientôt, Armin.

Could we set working dir of pypy_execute_source_ptr()?
by Yicong Huang 11 Jun '15

11 Jun '15

Here is a typcial scenario: We read a python file from a path and got (char*) buffer of the file content. And then we passed the char* buffer to pypy_execute_source_ptr() to execute. However, pypy_execute_source_ptr() looks like to assume the working dir as pypy_home. And if the python file import a local file in the path, it failed. Alternative method, could we have a pypy_execute_source_ptr(path pyFile, void *ptr)? The first argument indicates the path of python file.

Hi, I see more activity on py3k than py3.3. What the branch you recommend to test Python3 support of PyPy ? py3k ? The next stable release of PyPy3 will be based on py3.3 ? Regards. -- Ludovic Gasc (GMLudo) http://www.gmludo.eu/

Sandbox missing functions like 'fcntl'
by Dmitry Sagalovskiy 09 Jun '15

09 Jun '15

Hi! I am getting this error from the sandbox: Not Implemented: sandboxing for external function 'fcntl' I am using a custom controller process, and getting this in fdopen (pypy_interact bombs on something else before it gets to that point). After much digging, I think this is due to _check_fd_mode function in rpython/rlib/streamio.py. In sandbox mode, I think there is little use for this check, but since it's there, I need some workaround. Does anyone have recommendations? More generally, my team needs to decide if we can rely on the pypy sandbox to use in our product. It seems brilliantly designed, fast, and overall impressive. But there are these gaps in missing sandbox wrappers (there are others too, fcntl is just one that I don't know how to avoid). And I noticed some code that indicates that it is not supported on Windows -- is that the case? What are the sandbox's prospects, within the larger future of pypy? Dmitry

How to use interperter level code from a module for app level code in another module
by Yicong Huang 09 Jun '15

09 Jun '15

Hi, Some builtin modules only expose interpreter level function, e.g. in builtin module select: appleveldefs = { } interpleveldefs = { 'select': 'interp_select.select', 'error' : 'space.fromcache(interp_select.Cache).w_error' } And for a new built model, how to import and use that interpreter level function in app level code? We tried to import the module in app level code, but failed. e.g., in a new built module: interpleveldefs = { } appleveldefs = { 'test_api': 'app_test.test_api', } In app_ test.py, we tried to import the module, but neither of below could succeed: import select => ImportError: No module named select import pypy.module.select =>ImportError: No module named pypy

Getting a backtrace out of the sandbox
by Lukas Barth 05 Jun '15

05 Jun '15

Hi everyone, I'm using the pypy sandbox, with a slightly modified pypy_interact.py script. Basically, I'm starting pypy-c with a '-c "from foo import bar\nbar()' command line argument instead of running a script directly. After that, I do sandproc.communicate("") to get the result of the script. Now, this all works fine. I only have a problem if there's a problem in the sandboxed script. If there's an exception, the only thing I get is a > OSError: the sandboxed subprocess exited with code 1 Is there any way of actually getting the backtrace? Thanks a lot, Lukas
