Bug 1274655 - Resolve changeset when only repo is defined; r=mshal Previously, we required both or none of MOZ_SOURCE_REPO and MOZ_SOURCE_CHANGESET to be defined. This logic was established in 51029f4d82d3 (bug 1247162). There appears to be no good reason why we require MOZ_SOURCE_CHANGESET if MOZ_SOURCE_REPO is defined. After all, if we have a checkout we should be able to resolve the revision. This commit changes the logic to resolve the changeset when not defined. We still error if MOZ_SOURCE_REPO is defined but we can't resolve the changeset. I can't imagine this breaking anything. This change will be necessary to appease TaskCluster tasks once mozharness is changed in a subsequent commit to define MOZ_SOURCE_REPO. Buildbot and TC each have their own way of specifying the source revision. Rather than change mozharness, it feels easier to just have the build system derive things. This decision is further justified by the fact there is a chicken and egg problem in mozharness: the environment variable dict is resolved before source directory population. So, we'd need to teach mozharness about TC's VCS mechanism, which it currently has no knowledge of. I'd rather not do that. MozReview-Commit-ID: ANaoGbPGWj2
