repo-updater: Skip listing conflicting repos when sourcing fails
Created by: tsenart
This commit makes it so we don't list conflicting repos when sourcing
fails. When len(sourced) == 0
, by construction, there won't be any
conflicting repos.
What was happening instead, was that we were loading all repos from the
repo table, because sourced.Names()
was empty, and no other predicates
were included in the resulting query.
This bug was introduced in https://github.com/sourcegraph/sourcegraph/pull/16516, which made it so we don't abort the sync when there are authorization errors during sourcing, so that we'd end up removing repos associated with that external service in that event.
Fixes #16679 (closed)
