# WL#6404 - Add rewrite-db option to mysqlbinlog on RBR
#
# The test checks that there is no leak of the global variables used
# to decide whether rewrite-db option is ON or OFF.
#
# The test checks this by creating two tables in two different databases.
# insert rows in both of them.
#
# Read the binlog file using the new option --rewrite-db="db1->db3" and
# writing in the .sql file.
#
# On applying the .sql file on database db3, we get an error since not
# all events are converted for database db3. Only DB1 is converted to db3.
# The db2 event cause the error.
