BUG#39325 Server crash inside MYSQL_LOG::purge_first_log halts replicaiton The patch reverses the order of the purging and updating events for log and relay-log.info/index files respectively. This solves the problem of having holes caused by crashes happening between updating info/index files and purging logs. NOTE: This is a combined patch for BUG#38826 and BUG#39325. This patch is based on bugteam tree and takes into account reviewers suggestions.
