Bug 1490801

Description of problem:
spacewalk-repo-sync is the handy tool to sync all children of a base channel. It will hard fail if any child channel doesn't have an associated repo.

We have a base channel for CentOS 7, child channels for each additional CentOS repo, and some mirrors of third party repositories for vendor software. These all need to be sync'd on a regular basis, and spacewalk-repo-sync seems to be the right tool for the job.

We also have a handful of child channels which contain software pushed via rhnpush, or uploaded via the spacewalk webui. These repositories have no upstream source, and thus have no repositories.


Version-Release number of selected component (if applicable):
2.6 currently installed, but code is unchanged as of master for 2.7.

How reproducible:
Always

Steps to Reproduce:
1. Create a child channel with no associated repository
2. Try to run spacewalk-repo-sync with -p
3. 

Actual results:
Command fails with "Channel foo-centos7-x86_64 Channel has no URL associated"

Expected results:
All child channels with associated repositories should be synchronised.
All child channels with no associated repository should be ignored.

Additional info:
I will submit a github pull request for this shortly, and update this ticket with the link.
