ALTER TABLE {$NAMESPACE}_repository.repository
  ADD UNIQUE KEY `key_local` (localPath);
Guarantee repositories have unique local paths Summary: Ref T4039. Long ago these were more freely editable and there were some security concerns around creating a repository, then setting its local path to point somewhere it shouldn't. Local paths are no longer editable so there's no real reason we need to provide a uniqueness guarantee anymore, but you could still make a mistake with `bin/repository move-paths` by accident, and it's a little cleaner to pull them out into their own column with a key. (We still don't -- and, largely can't -- guarantee that two paths aren't //equivalent// since one might be symlinked to the other, or symlinked only on some hosts, or whatever, but the primary value here is as a sanity check that you aren't goofing things up and pointing a bunch of repositories at the same working copy by mistake.) Test Plan: - Ran migrations. - Grepped for `local-path`. - Listed and moved paths with `bin/repository`. - Created a new repository, verified its local path populated correctly.
