This change avoid the following corner case: T1: lsn=100 is executing handle_commit T2: lsn=100 is requested to append from leader again, triggering raft_event and retrieving the existed rreq from map T3: lsn=100 committed, the rreq is removed from map and is cleared T4: during the raft_event process, the rreq has already been cleared, preventing further processing

This pr aims to resole a corner case, but using last_lsn/last_term rather than last_commit_lsn might be more dangerous and requires more consideration, so covert it to raft ATM. |
