Revision as of 01:33, 25 July 2012 by Dmalcolm (talk | contribs) (Porting status: nose is in)

A python 3 stack was added to Fedora in Fedora 13, parallel-installable with the "main" Python 2 stack, and it is gradually growing additional RPMs, as more code is ported to Python 3.

Note that /usr/bin/python is still Python 2.

Porting status

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Please let us know if this information is out-of-date.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
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
django Django - there's an experimental branch in bitbucket, but as of 2010-04-09 it doesn't appear to have "official" releases
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
libvirt libvirt-python Porting has not yet started
libxml2 libxml2-python Porting doesn't seem to have started
MySQLdb MySQL-python As of 2011-07-25, said " Python-3.0 will be supported in a future release."
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

Python 2 modules that are not going to be ported to Python 3

Python Module Fedora Python 2 package Notes
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
BeautifulSoup python-BeautifulSoup 3.1.0 adds Python 3 support, but reportedly doesn't work as well as 3.0.8 (See and ). However, beautifulsoup4 (see above) adds Python 3 support
dbus dbus-python rhbz 538616 python 3 requires using gdbus through introspection.
gtk pygtk2 The old C-based bindings are not going to be ported. Instead, the "Gtk" module can be accessed from pygobject introspection with upstream trying to make it easy to transition from PyGTK
