Moving to newer Python versions

The ultimate goal is to migrate Launchpad to Python 2.6. Rather than go straight to Python 2.6, we are focusing on Python 2.5 first as a stepping stone. People involved in this effort: maxb, gary, salgado, barry, simono. We are treating this work as a sprint; come join us on #launchpad-sprint on freenode.

Update 2009-10-24: The sprint has concluded. We were successful in getting Launchpad to work under 2.5 + Zope Toolkit. Python 2.6 support will be postponed until the Lucid timeframe.

Relevant tagged bugs: https://bugs.launchpad.net/launchpad-foundations/+bugs?field.tag=python-upgrade

Branches

• https://code.launchpad.net/~launchpad-dev/launchpad/python-migration was the master branch tracking the migration to Python 2.5. This was branched off of devel. Now that we have a working Python 2.5 + ZTK upgrade branch, the pure Python 2.5 branch is abandoned.

• https://code.launchpad.net/~launchpad-dev/launchpad/ztk-2.5 is the python-migration branch with the latest Zope Toolkit updates, still on Python 2.5. It is the master result of the sprint and earmarked for landing on devel once Week 1 of 3.1.11 opens.

• https://code.launchpad.net/~launchpad-dev/launchpad/python-migration2.6 is the ztk-2.5 branch with changes to get us on Python 2.6. It is not complete.

• https://code.edge.launchpad.net/~salgado/shipit/py2.5 is the shipit branch that make it possible to run shipit under 2.5

• https://code.edge.launchpad.net/~salgado/canonical-identity-provider/ztk-2.5 has a test fix, needed when we change to ztk on 2.5

Review process

You should submit merge proposals into the appropriate branch. gary, salgado, and barry will review all branches and we'll use a lightweight review process to manage this (simple cover letters, 5-minute reviews). Once approved, you can land your change by just merging it into a pristine local copy of the destination and pushing it; there is no pqm gateway.

Merge flow

In general, we'll merge from devel -> ztk-2.5 -> python-migration2.6.

Things you'll need to do

• The Makefiles of pygettextpo & pygpgme (in sourcecode/) make direct reference to Python 2.4, you'll need to amend them appropriately.

Known/Open issues

Bustimications

• The extension modules in your sourcecode directory will have been built for Python 2.4 and these will break for your 2.5 branch. The simple thing to do is to move your old sourcecode aside and run utilities/rocketfuel-get to get it again with Python 2.5. A more complex but useful thing to do to manage sourcecode directories for multiple python versions is:

  cd ~/launchpad/lp-sourcedeps
  mkdir 2.5
  cd 2.5
  ln -s ../download-cache
  ln -s ../eggs
  mkdir sourcecode
  cd sourcecode
  for i in ../../sourcecode/*; do bzr checkout --lightweight "$i"; done

  and now point utilities/link-external-sourcecode to ../../lp-sourcedeps/2.5 - if you do that you'll need to be aware that rocketfuel-get won't know about it, and your extra directories will require occasional manual updating.

• The pytz source package has a not-so-mysterious problem, hence we have eggs in download-cache.

Cleanup potential

• Eventually we should get rid of all the scripts hardcoded /usr/bin/pythonX.Y and use buildout's shebang munging.

• scripts/branch-rewrite.py uses /usr/bin/pythonX.Y -u. We should figure out if this is significant and why this script has to be different from other scripts.

• scripts/ftpmaster-tools/_syncorigins.py uses /usr/bin/env pythonX.Y... why?!

• cronscripts/mirror-prober.sh and cronscripts/nightly.sh are invoking python scripts with explicit interpreters. Why are they not using the shebangs? This leads to versions being defined in two places.

Python 2.5 w/Zope Toolkit

This is a branch off of python-migration which uses Python 2.5 and the Zope Toolkit.

test failures

• lib/canonical/shipit/tests/../doc/shipit.txt
  • Salgado has a branch that fixes this
• lib/canonical/signon/browser/tests/loginservice-unauthorized-view.txt
  • Salgado has a branch that fixes this

Python 2.6

This is the ztk-2.5 branch, converted to use Python 2.6.

Also, a multitude of modules of modules (sha, md5, sets, ...) are deprecated in Python 2.6, and many tests will fail merely because of unexpected DeprecationWarnings (but see below).

Getting started

• Apply this patch and re-run bin/buildout to temporarily suppress the turning of warnings into errors. There are DeprecationErrors coming from Twisted that we can't seem to turn off any other way.

• sudo apt-get install python-pyasn1 (for lp:twisted)
