Description (last modified by Christian Boos)

With Genshi having been ported to Python 3, we could start thinking about how we can achieve the same with Trac. As a first step, we should check if our dependencies have a Python 3 port:

Database backends

SQLite builtin sqlite3, PySqlite?
PostgreSQL
MySQL

Version control bindings

Subversion unlikely (1)
Mercurial unlikely (2)

Web frontends

Apache mod_wsgi

Others

setuptools (Distribute) works (3)
Genshi py3k branch
Babel #bl209
pytz unofficial, but it seems official 2011d can be easy_install'ed
docutils works (4)
pygments works (1.4)

Notes

  • svn: not much activity on the bindings; rather go the svn.exe way
  • hg: after 2 SoC projects already, the efforts seem to have stalled
  • distribute: seems ok on Linux, "works" more or less on Windows; might be worth to wait for distutils2
  • docutils: seems it was ported and works on Linux, but easy_install docutils on Windows hangs… Installing docutils-0.7.tar.gz also hangs, so it seems it's not distribute's fault.

Once we have at least one backend, VC binding and frontend ready, the next step would be playing with 2to3 and see what comes out.

Let's set the milestone tentatively to 0.14.

There is also a 3to2 tool, and rumors here at PyCon that 3to2 will (soonish?) have the ability to take Python 3 code and output versions that will work for 2.7, 2.6, 2.5, and maybe even 2.4.

Replying to ecarter:

For projects that need to be migrating away from Python 3? ;-)
