This version of the patchset passes the existing tests, since Raft is disabled by default. New tests were not added yet. Changes in v2: - The patch about setting applier->instance_id is reworked completely; - Found and attempted to fix a blocking issue 5827 about replicas too early registration; - Fixed lots of bugs in Raft code found by sanity checks in a console.
