Master_info contains:
|
|
- information about how to connect to a master
|
|
- current master log name
|
|
- current master log offset
|
|
- misc control variables
|
|
|
|
Master_info is initialized once from the master.info file if such
|
|
exists. Otherwise, data members corresponding to master.info fields
|
|
are initialized with defaults specified by master-* options. The
|
|
initialization is done through init_master_info() call.
|
|
|
|
The format of master.info file:
|
|
|
|
log_name
|
|
log_pos
|
|
master_host
|
|
master_user
|
|
master_pass
|
|
master_port
|
|
master_connect_retry
|
|
|
|
To write out the contents of master.info file to disk ( needed every
|
|
time we read and queue data from the master ), a call to
|
|
flush_master_info() is required.
|
|
|
|
To clean up, call end_master_info()
