fix libpypy-c.so needing certein versions
by Katelyn McNair June 22, 2016

June 22, 2016

I have been trying to install PyPy locally for the last 3 days. I didn't have Openssl, which install fine. But then PyPy started not liking the new version (libssl.so.1.0.1), so I got the archive for 1.0.0, and installed. But then PyPy didn't like that the .so files didn't have to correct version name in them. [katelyn@anthill bin]$ ./pypy ./pypy: /home/katelyn/lib/libssl.so.1.0.0: version `OPENSSL_1.0.1' not found (required by /home/katelyn/opt/pypy2-v5.3.0-linux64/bin/libpypy-c.so) ./pypy:… [View More]

PyParallel-style threads
by Omer Katz June 21, 2016

June 21, 2016

Hi all, There was an experiment based on CPython's code called PyParallel <https://github.com/pyparallel/pyparallel> that allows running threads in parallel without STM and modifying source code of both Python and C extensions. The only limitation is that they disallow mutation of global state in parallel context. I briefly mentioned it before on PyPy's freenode channel. I'd like to discuss why the approach is useful, how it can benefit PyPy users and how can it be implemented. Allowing … [View More]

W^X in the PyPy JIT?
by Edd Barrett June 9, 2016

June 9, 2016

Hi! Recently OpenBSD has started enforcing W^X [1] for all programs, unless the program is on a file system with a special 'wxallowed' flag. Regardless of the flag, a message is emitted to the dmesg buffer. Starting PyPy will emit such a message: pypy(62301): mmap W^X violation I suppose the memory the JIT is using for traces has been mapped W+X? Assuming this is the case, the security of PyPy (on all platforms) could be improved by mapping the memory W during trace compilation, and then re-… [View More]

by Matti Picus June 5, 2016

June 5, 2016

We are almost ready to release pypy3.3-v5.2-alpha1, but need some help to make sure all is OK. Please try the download packages here https://bitbucket.org/pypy/pypy/downloads also, if someone could check that the links related to pypy3.3 all work on this page that would be great http://pypy.org/download.html If the page is still showing PyPy3 2.4.0, wait 30 minutes or so from now and then hit refresh on your browser. Thanks, and kudos to the pypy3 team. Matti
