Problem: The following statements can cause the slave to go out of sync
if logged in statement format:
INSERT IGNORE...SELECT
INSERT ... SELECT ... ON DUPLICATE KEY UPDATE
REPLACE ... SELECT
UPDATE IGNORE :
CREATE ... IGNORE SELECT
CREATE ... REPLACE SELECT
Background: Since the order of the rows returned by the SELECT
statement or otherwise may differ on master and slave, therefore
the above statements may cuase the salve to go out of sync with
the master.
Fix:
Issue a warning when statements like the above are exectued and
the bin-logging format is statement. If the logging format is mixed,
use row based logging. Marking a statement as unsafe has been
done in the sql/sql_parse.cc instead of sql/sql_yacc.cc, because while
parsing for a token has been done we cannot be sure if the parsing
of the other tokens has been done as well.
Six new warning messages has been added for each unsafe statement.
binlog.binlog_unsafe.test has been updated to incoporate these additional unsafe statments.
