Today I spent a few hours testing and backporting yum-3.2.8 from CentOS 5.2 to CentOS 4.7. It wasn’t so hard to backport. Most of the time I have spent on testing and searching. Code is patched to allow sets, which are supported in python 2.3 
) and that’s almost all. Final rpms are available for testing here:

Everything works fine. Now it’s time to publish and make some public QA. As you can see, it handles obsolete packages!

Thanks for your work!
I get a lot of Python errors with the package, e.g. because python 2.3 doesn’t have a sorted() function. Are you still working on this? (I started porting some of those places to the old .sort() syntax, but it’s quite some work).
Ah, I forgot. I also get some StopIteration Exceptions because of some .next() calls.
Well,
I have production ready yum 3.2.19. See:
http://fs12.vsb.cz/hrb33/el4/hrb/testing/x86_64/repoview/letter_y.group.html
http://fs12.vsb.cz/hrb33/el4/hrb/testing/i386/repoview/letter_y.group.html
Get the hrb-release package from stable repo, disable the stable repo within the yum configuration and finally run:
yum update yum –enablerepo=hrb-testing

David – are you still working on this project? I just installed your yum rpms on rhel4.6 and everything works except for yum search. I get the following error –
[root@xxxxxxxxx yum-3.2]# yum search screen
Loaded plugins: allowdowngrade
Traceback (most recent call last):

Any ideas? Thanks for doing this work. The feature difference between yum 2x and 3x is significant and for those of us stuck with rhel4 your yum back port is a big deal.
Edward,
I have just fixed “yum search”. The new release yum-3.2.19-18.el4.hrb.7.noarch is available within repos:
