= 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

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

== Interesting branches ==

 * https://code.launchpad.net/~maxb/launchpad/python2.5 tracks `lp:launchpad/stable` (or occasionally `devel`), on a manual basis, and acts as a one-stop-shop for something that people can check out and build using Python 2.5

 * https://code.launchpad.net/~gary/launchpad/py25 is gary's branch tracking the upgrade.

 * ''add yours here''

== Launchpad code itself ==

Remaining changes in `python2.5` branch:
 * Changed `PYTHON_VERSION` in Makefiles
 * Changed shebang in `cronscripts/*`, `scripts/*`,

== Known issues ==

 * The pytz source package has a [[https://launchpad.net/bugs/438634|mysterious problem]]. The work around is to [[http://pypi.python.org/packages/2.5/p/pytz/pytz-2009l-py2.5.egg#md5=b41c8cacb5f4a8a64db05afbdf3ef9ef|download the 2.5 egg]] and put that in your `download-cache/dist` directory.

== Launchpad source dependencies (sourcecode bzr trees) ==

The `Makefile`s of pygettextpo & pygpgme make direct reference to Python 2.4, you'll need to amend them appropriately.

== Test Status for lp:~maxb/launchpad/python2.5@9026 based on lp:launchpad/stable@9539 ==
