epriestley 2dfe79cfc7 When updating revisions in response to commits, reuse previously generated diffs ... Summary: Fixes T10968. In rare situations, we can generate a diff, then hit an error which causes this update to fail. When it does, we tend to get stuck in a loop creating diffs, which can fill the database up with garbage. We saw this once in the Phacility cluster, and one instance hit it, too. Instead: when we create a diff, keep track of which commit we generated it from. The next time through, reuse it if we already built it. Test Plan: - Used `bin/differential attach-commit <commit> <revision>` to hit this code. - Simulated a filesystem write failure, saw the diff get reused. - Also did a normal update, which worked properly.
