Getting Started with Pypy on OpenSuse

From: andrew cooke <andrew@...>

Date: Sat, 3 Sep 2011 17:52:39 -0300

Here's what I did:

 - on my desktop (or any machine with a decent amount of memory, which means
   not my laptop) as root
     hg clone https://bitbucket.org/pypy/pypy /opt/pypy-hg

 - check i had the dependencies installed (these are the same you need for
   building python normally - things like bzip, etc).  there's a list at 
   http://pypy.readthedocs.org/en/latest/getting-started-python.html

 - check for a "good" revision (one with a green bar) at 
   http://buildbot.pypy.org/nightly/trunk/ and update to that
     cd /opt/pypy-hg
     hg update -r XXX

 - use an existing python2.7 to build
     cd pypy/translator/goal
     python2.7 translate.py --opt=jit targetpypystandalone.py
   (takes about an hour)

 - add a symlink to /usr/bin
     cd /usr/bin
     ln -s /opt/pypy-hg/pypy/translator/goal/pypy-c pypy

 - install distribute
     cd /tmp
     wget http://python-distribute.org/distribute_setup.py
     pypy distribute_setup.py

 - install pip
     wget https://raw.github.com/pypa/pip/master/contrib/get-pip.py
     pypy get-pip.py

 - install pytest
     /opt/pypy-hg-1.6/bin/pip install py.test

 - to install on my laptop, I copied across the /opt/pypy-hg and repeated
   the rest of the steps.

Was rather disappointed to find that some code of Paulina's (which I helped
write, although it's since been modified) runs 4x slower with pypy that with
CPython 2.7.  If it's similar to what I remember it's mainly list
comprehensions, maps and reduces, with some file reading and writing.
