WL#2668: SHOW SLAVE STATUS: Show errors that keep replication from starting or cause replication to stop
Affects: WorkLog-3.4 — Status: Un-Assigned — Priority: Medium
Any error, or warning that keep replication from starting or that causes it to stop should be listed when the user does mysql> SHOW SLAVE STATUS\G; Notes from Guilhem Bichot: If somebody decided that even this Slave_IO_State is not enough, then we should create a WL task. But if I was asked if this is enough, I'd say yes it is enough. The WL task could read: - change some of sql_print_*() in slave.cc, sql_repl.cc to slave_print_error() - modifiy slave_print_error() to mention if it's an error of the I/O or of the SQL thread, and maybe sometimes we don't want the "Error" word because it's more of a warning (like "lost connection, trying to reconnect")?, but then we have the issue that the column in SHOW SLAVE STATUS is named Last_Slave_*Error*.
