Not sure where to post this.

I think i have found a problem in  cobbler reposync.

Sometimes if a rpm is partially downloaded and /usr/bin/reposync is stopped,
say by a collegue rebooting the server, grrr.
/usr/bin/reposync wont continue and throws an error untill the file is
deleted. e.g.
Traceback (most recent call last):
  File "/usr/bin/reposync", line 264, in ?
    main()
  File "/usr/bin/reposync", line 245, in main
    path = repo.getPackage(pkg)
  File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 652, in
getPackage
    cache=cache
  File "/usr/lib/yum-plugins/rhnplugin.py", line 299, in _getFile
    raise yum.Errors.RepoError, \
yum.Errors.RepoError: failed to retrieve
getPackage/openoffice.org-impress-2.0.4
-5.4.17.1.x86_64.rpm from rhel-x86_64-server-productivity-5
error was [Errno 9] Requested Range Not Satisfiable
cobbler reposync failed


This is not caught by my script because cobbler terminates with a return
code of 0, but cobbler knows it has failed.

Looking at action_reposync.py

               rc = sub_process.call(cmd, shell=True)
               if rc !=0:
                   raise CX(_("cobbler reposync failed"))

The return code from /usr/bin/reposync is being caught, but it looks like
what ever handles the exception raised does not pass it on.
Sorry my python is non existant so i cant follow it any further, any one
know how to make a quick fix?
