Main Code Files MySQL

These file are all in the sql directory:

  • creating/writing/deleting a binlog.
  • log_event.*: all event types and their methods.
  • slave.*: all the slave threads' code.
  • sql_repl.*: all SQL commands related to replication (START SLAVE, CHANGE MASTER TO). Also all the master's high-level code about replication (binlog sending, a.k.a.COM_BINLOG_DUMP). For example, binlog sending code is in, but uses low-level commands (single event reading) which are in
  • repl_failsafe.*: unfinished code about failsafe (master election if the primary master fails).This file will probably be heavily reworked. Presently it's almost unused.
