Python modules that appear to not yet be ready for Python 3 packaging

Please let us know if this information is out-of-date.

FIXME: add note about if a python3 version should be packaged

Python Module	Fedora Python 2 package	Upstream status of Python 3	Fedora Python 3 package
	blender	Blender 2.5 migrated its embedded version of python from Python 2 to Python 3. However, Blender 2.6's schedule suggests this version might not be regarded as stable in time for Fedora 13 (Upstream ships with a bundled copy of 3.1; we would want to build against a system copy of Python 3)	Blender 2.6 won't be ready in time for Fedora 13
	mod_python	Upstream mod_python has effectively stopped since February 2007. ..."You also will never see a version of mod_python for Python 3.X as that is going to require a radical rewrite"... with various suggestions including moving to mod_wsgi
augeas	python-augeas	dmalcolm has experimented with porting this to python 3
Cheetah	python-cheetah	As of 2010-02-02, upstream site reports that Python 3.xx support will be in Cheetah v3.0, but that it is "still in planning"
cracklib	cracklib-python	Looking at cracklib-2.8.16, looks like the module needs some work to port (e.g. module initialization), and uses automake so may need work to build multiple times
Crypto	python-crypto	Experimental patch on upstream list http://lists.dlitz.net/pipermail/pycrypto/2010q1/000182.html , however upstream forbids US contributors to the project, which seems to have ruled out the patch (and rules out dmalcolm from completing the port) Explanation of the ban on US contributors. If we have any lawyers familiar with the export regulations perhaps we can get the ban lifted?
dbus	dbus-python	Patch created by Fedora contributor John Palmieri sent upstream, awaiting upstream review - also GDBus can be used through pygobject introspection	rhbz 538616
django	Django	http://wiki.python.org/moin/PortingDjangoTo3k - there's an experimental branch in bitbucket, but as of 2010-04-09 it doesn't appear to have "official" releases
enchant	python-enchant	Uses SWIG with some special-casing; appears to need some porting
gtk	pygtk2	Not going to be ported	the Gtk module can be accessed from pygobject introspection with upstream trying to make it easy to transition from PyGTK
krbV	python-krbV	Implemented in C, would need porting (with 2to3c ?)
ldap	python-ldap	Porting discussed on upstream mailing list on 2009-09-03 but appears not to be done yet
libxml2	libxml2-python	Porting doesn't seem to have started
nss	python-nss	Looks like we need to port it, and would be non-trivial
parted	pyparted	Looks like we need to port it
PIL	python-imaging	As of 2010-01-28, upstream website says "The current free version is PIL 1.1.7. This release supports Python 1.5.2 and newer, including 2.5 and 2.6. A version of 1.1.7 for 3.X will be released later." A 2010-02-21 mailing list post suggests that the port is stalled
pylons	python-pylons	As of 2010-04-09, it's on the future roadmap for 1.1; see also http://pylonshq.com/project/pylonshq/ticket/425
sphinx	python-sphinx	A port to Python 3 has been proposed as a GSOC 2010 project
wx	wxPython	As of 2010-02-03, appears not to be ported yet; see http://stackoverflow.com/questions/720806/wxpython-for-python-3-0
xdg	pyxdg	Appears to not yet be ported; see RHBZ #555620
