rpl_known_bugs_detection.test

视频监控网络部分的协议ddns,的模块的实现代码,请大家大胆指正.

# Test to see if slave can detect certain known bugs present
# on the master, and appropriately decides to stop
# (assuming the bug is fixed in the slave, slave cannot of course
# imitate the bug, so it has to stop).

# This is to test that slave properly detects if
# master may suffer from:
# BUG#24432 "INSERT... ON DUPLICATE KEY UPDATE skips auto_increment values"
# (i.e. on master, INSERT ON DUPLICATE KEY UPDATE is used and manipulates
# an auto_increment column, and is binlogged statement-based).
