Running yum-3.2.8 on CentOS 4.7


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 :o) 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).

Andre - Feb 5, 2010

Ah, I forgot. I also get some StopIteration Exceptions because of some .next() calls.

David Hrbáč - Feb 2, 2010

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 Regards, David

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): File “/usr/bin/yum”, line 29, in ? yummain.user_main(sys.argv[1:], exit_code=True) File “/usr/share/yum-cli/yummain.py”, line 229, in user_main errcode = main(args) File “/usr/share/yum-cli/yummain.py”, line 104, in main result, resultmsgs = base.doCommands() File “/usr/share/yum-cli/cli.py”, line 348, in doCommands return self.yum_cli_commands[self.basecmd].doCommand(self, self.basecmd, self.extcmds) File “/usr/share/yum-cli/yumcommands.py”, line 559, in doCommand return base.search(extcmds) File “/usr/share/yum-cli/cli.py”, line 696, in search for (po, keys, matched_value) in matching: File “/usr/lib/python2.3/site-packages/yum/__init__.py”, line 1630, in searchGenerator sort_func = operator.itemgetter(0) AttributeError: ‘module’ object has no attribute ‘itemgetter’ 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.

David Hrbáč - Dec 3, 2010

Edward, I have just fixed “yum search”. The new release yum-3.2.19-18.el4.hrb.7.noarch is available within repos:
