<<TableOfContents>>

With Lucid fast approaching, efforts to actually migrate Launchpad to Python 2.6 are getting under way.

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

== Branches ==

=== Obsolete branches from the last push, which got us to 2.5 ===
 * https://code.launchpad.net/~launchpad-committers/launchpad/python-migration2.6 is the incomplete work done on Python 2.6 compatibility mixed with ZTK upgrade work since cherrypicked and landed.
 * https://code.launchpad.net/~launchpad-committers/launchpad/python-migration2.6-rebased is the above rebased on recent devel dropping then-empty revisions.

Remaining useful content of these branches:
 * shebang updates / Makefile PYTHON_VERSION updates all over the place -- ''redone in salgado's branch below''
 * Deprecation warning suppression. -- ''cherrypicked into salgado's branch below''
 * versions.cfg change: lazr.smtptest = 1.2 -- ''disregarded, there is no known reason why this was Python 2.6 related''

=== The new effort ===
 * https://code.launchpad.net/~salgado/launchpad/real-python-2.6 -- the most current work so far.

== Known/Open issues ==

'''Today I've tried building a python-migration2.6-rebased branch (after merging devel) but it failed with a max recursion depth exceeded, very similar to what's described in http://bitbucket.org/tarek/distribute/issue/63/distribute-leaves-system-setuptools-in-inconsistent (although that's supposed to be fixed in our version of buildout). http://paste.ubuntu.com/409662/ is the actual error that I got.''' -- GuilhermeSalgado

=== Setup caveat ===
 * The extension modules in your `sourcecode` directory will have been built for Python 2.5 and these will break for your 2.6 branch. The simple thing to do is to move your old `sourcecode` aside and run `utilities/rocketfuel-get` to get it again with Python 2.6. A more complex but useful thing to do to manage `sourcecode` directories for multiple python versions is: {{{
cd ~/launchpad/lp-sourcedeps
mkdir 2.6
cd 2.6
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/2.6` - 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.

=== Cleanup potential ===
 * Is there any reason we need ipython-0.9.1-py2.5.egg in egg, not tarball, form?
  * Presumably we could bin the wadllib 0.1 eggs too.
 * 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.

=== Situation ===

A multitude of modules of modules (sha, md5, sets, ...) are deprecated in Python 2.6, and many tests would fail merely because of unexpected !DeprecationWarnings, so we've had to jump through multiple hoops all over the place to suppress these. Ultimately we need a plan for removing these suppressions, because we ''want'' to know about deprecation long-term.
