I've been experimenting with running yum under PyPy.

This is with pypy-1.9 rpms on an x86_64 Fedora 17 guest

What I had to do

  • build extension modules:
    • bug in distutils/sysconfig_pypy.py with more than one option in CFLAGS (need to split on spaces)
      • TODO: add patch to our rpms
      • TODO: send patch upstream
    • rpm: I used rawhide (=f18)'s rpm.rpm, recompiling with pypy as per my python3 patch in https://bugzilla.redhat.com/show_bug.cgi?id=531543
    • yum-metadata-parser (compiled OK)
    • pycurl (compiled OK)
  • I hacked out a call to os.statvfs from yum/yumRepo.py:_getFile (line 795)
    • TODO: implement it for PyPy

Running it

 sudo pypy /usr/bin/yum YUM-ARGUMENTS

with suitable PYTHONPATH= and LD_LIBRARY_PATH= hacks to deal with my hacked up installation of extension modules

What I've tested so far:

  • yum history (looks sane)
  • yum --assume-no update PACKAGE (looks sane)
  • yum --assume-no remove glibc (looks sane; same output as with CPython, apart from this:
