# binlog_start_pos is the postion of the the first event in the binary log
|
|
# which follows the Format description event. Intended to reduce test suite
|
|
# dependance on the Format description event length changes (e.g. in case
|
|
# of adding new events). Evaluated as:
|
|
#
|
|
# binlog_start_pos = 4 /* binlog header */ +
|
|
# (Format_description_log_event length)
|
|
#
|
|
# Format_description_log_event length =
|
|
# 19 /* event common header */ +
|
|
# 57 /* misc stuff in the Format description header */ +
|
|
# number of events +
|
|
# 1 /* Checksum algorithm */ +
|
|
# 4 /* CRC32 length */
|
|
#
|
|
# With current number of events = 171,
|
|
#
|
|
# binlog_start_pos = 4 + 19 + 57 + 171 + 1 + 4 = 256.
