      Add raft_pop_entry(). · 876f8d7c
      Yossi Gottlieb authored
      This is required to allow append-only persistent log formats, where
      raft_append_entry() is called but may be reverted later on.

      Remove RAFT_LOGTYPE_SNAPSHOT · 700eebe6
      Willem Thiart authored
      The RAFT_LOGTYPE_SNAPSHOT was a bad design choice. It's better to not
      have this marker entry so that users don't have to check for the log
      entry type in the callbacks. Also, loading a snapshot correctly created
      this marker entry, but the compaction side did not. It's better to
      remove this log type than to fix this asymmetry.
      
      Fixes the following edge cases:
      - Server crashes if the last snapshot index is N and a appendentries
      message pops entries all the way back to index N.
      - Server sends an appendentries message with an invalid prev_log_idx and
      prev_log_term, causing the peer to crash.

      Ignore RequestVote when leader is established. · 6cac5767
      Yossi Gottlieb authored
      This behavior is described in the original Raft paper and is required to
      prevent removed nodes from disrupting the cluster.
      
      This causes other problems though, as a split node may trigger election
      which is rejected but leaves it with a future term.  The generally
      accepted solution for this appears to be the use of PreVote RPC to avoid
      election that can never succeed.
