Google Code-in 2011 Organization MoinMoin Wiki Task test moin2 with pypy 1.7

completed by: Julian Brost

Abstract

pypy 1.7 was released recently (bug fixes and speed improvements).

We need testing whether moin2 works with it (and how fast it is).

download pypy 1.7 (and 1.6), use the binary they offer!
create some virtualenvs - for (c)python 2.6 or 2.7, for pypy 1.6 and 1.7
do manual testing
run all our unittests using py.test
- how long does it take?
run ab (apachebench) against the different setups
- always use same concurrency / request count when comparing performance!
- always start with a fresh process (because of the JIT of pypy)
stay in contact with moin devs on #moin-dev on IRC

Deliverables: wiki page:

document test failures and problems that do happen with pypy, but do not happen with cpython
document performance values for cpython, pypy 1.6 and 1.7, how much faster is pypy 1.7 compared to 1.6 / cpython?
- document how you measured performance
if you find bugs in moin2 that are easy to fix to make it work better with pypy, submit some changesets
if you find hard to fix bugs in moin2, file bitbucket issues
if you find issues in pypy, file issues to their issue tracker
