    Description

      Hi,

      mysqlbinlog detects a "Corrupted Binlog" event when manipulating datetime fields with microsecond precision.

      SET binlog_format = ROW;
      FLUSH LOGS;
      CREATE TABLE t1_timestamp (a serial, b timestamp);
      CREATE TABLE t1_timestamp6 (a serial, b timestamp(6));
      INSERT INTO t1_timestamp VALUES (NULL,NOW(6));
      INSERT INTO t1_timestamp6 VALUES (NULL,NOW(6));
      INSERT INTO t1_timestamp VALUES(NULL,NOW(6));

      And we can now look in the content of the binary log:
      mysqlbinlog -vvvv --base64-output=DECODE-ROWS mariadb-bin.000006
