1
下载最新的go-mysql   go-log
https://github.com/siddontang/go-log.git
https://github.com/siddontang/go-mysql.git
[root@kb3 siddontang]# pwd
/opt/kingbus/src/github.com/flike/kingbus/vendor/github.com/siddontang
[root@kb3 siddontang]# ls
go  go-log  go-mysql  go-mysql_bak  tmp


2修改新的go-mysql中的代码对照旧的go-mysql
[root@kb3 replication]# pwd
/opt/kingbus/src/github.com/flike/kingbus/vendor/github.com/siddontang/go-mysql/replication
[root@kb3 replication]# vi const.go 
     91         //add by kingbus
     92         TRANSACTION_CONTEXT_EVENT //36
     93         VIEW_CHANGE_EVENT         //37
     94         XA_PREPARE_LOG_EVENT      //38

	 
	 
	190         case TRANSACTION_CONTEXT_EVENT:
    191                 return "TRANSACTION_CONTEXT_EVENT"
    192         case VIEW_CHANGE_EVENT:
    193                 return "VIEW_CHANGE_EVENT"
    194         case XA_PREPARE_LOG_EVENT:
    195                 return "XA_PREPARE_LOG_EVENT"

	
	
[root@kb3 replication]# vi binlogsyncer.go 

	 29         //add by kingbus, the uuid of sycner, using in set salve_uuid
     30         ServerUuid string

	 
	 
	 
[root@kb3 replication]# vi event.go  
	203 //by kingbus
    204 type PreviousGtidsLogEvent struct {
    205         GSet *MysqlGTIDSet
    206 }
    207 
    208 func (e *PreviousGtidsLogEvent) Decode(data []byte) error {
    209         var err error
    210         e.GSet, err = DecodeMysqlGTIDSet(data)
    211         if err != nil {
    212                 return err
    213         }
    214         return nil
    215 }
    216 
    217 func (e *PreviousGtidsLogEvent) Dump(w io.Writer) {
    218         if e.GSet != nil {
    219                 fmt.Fprintf(w, "PreviousGtids: %s\n", e.GSet.String())
    220         }
    221         fmt.Fprintln(w)
    222 }

	
3修改kingbus认证方式
[root@kb3 siddontang]# vi /opt/kingbus/src/github.com/flike/kingbus/mysql/auth.go 
    116         checkAuth := gomysql.CalcCachingSha2Password(c.salt, password)  ##原来是CalcPassword
