# Check if a given SQL statement (->$my_stmt) / AUTOCOMMIT mode / #
|
|
# storage engine somehow involved causes COMMIT or ROLLBACK. #
|

# #
|
|
# #
|
|
# The typical test sequence #
|
|
# ------------------------- #
|
|
# 1. master connection: INSERT without commit #
|
|
# check table content of master and slave #
|
|
# 2. master connection: EXECUTE the statement #
|
|
# check table content of master and slave #
|
|
# 3. master connection: ROLLBACK #
|
|
# check table content of master and slave #
|
|
# 4. flush the logs #
|
|
# #
|
|
# The variables #
|
|
# $show_binlog -- print binlog entries #
|
|
# 0 - default + fits to the file with #
|
|
# results #
|
|
# 1 - useful for debugging #
|
|
# This variable is used within #
|
|
# include/rpl_stmt_seq.inc. #
|
|
# $manipulate -- Manipulation of the binary logs #
|
|
# 0 - do nothing #
|
|
# 1 - so that the output of SHOW BINLOG #
|
|
# EVENTS IN <current log> contains only #
|
|
# commands of the current test sequence #
|
|
# This is especially useful, if the #
|
|
# $show_binlog is set to 1 and many #
|
|
# subtest are executed. #
|

# This variable is used within #
