Talking to Martin, he agreed to take 'repoclosure' together with 'conflicts', because they are highly similar and could be useful. Talking to Tim, we agreed to temporarily remove tree_compose from AutoQA. Tim will develop it separately (fedorahosted, github), and we can then use it as a basis for new tests that need to operate on fresh composes.
Please review my patch:
$ git log --reverse origin/master..origin/test_cleanup
I'll create appropriate origin/archive_* branches once the patch is approved.
Pushed, branches created.
Tim, let us know when you create a new home for compose_tree, thanks.
