PyPy compatibility wiki

Hello!

This is the place to keep up to date informations about PyPy's compatibility issues. It is also the place to keep all links to patches necessary, but not merged upstream, to work with PyPy.

Differencies between PyPy and CPython are mentioned on PyPy compatibility page.

As a general rule of thumb, Python packages that work should not be listed here (they mostly work). Notable examples include Django, Twisted, SQLAlchemy or Pylons. C extensions known to work with PyPy should be noted (default being not known to work).

Python modules known not to work

  • Mercurial is known not work on PyPy, due to transient leaks of file descriptors.
