# ==== Purpose ====
#
# MySQL 5.7 introduced two new values for GTID_MODE: OFF_PERMISSIVE
# and ON_PERMISSIVE. In order for 5.6 to replicate from such a master,
# a slave that uses GTID_MODE=OFF accepts any master GTID_MODE that
# begins with OFF (i.e., regex /OFF.*/), and a slave that uses
# GTID_MODE=ON accepts any master GTID_MODE that begins with ON.
#
# This test verifies that the slave accepts such values for GTID_MODE.
#
# ==== Implementation ====
#
# Use debug symbols to simulate that the master uses unknown values
# for GTID_MODE.
#
# ==== Related bugs and worklogs ====
#
# WL#7083: GTIDs: set gtid_mode=ON online
# - OFF_PERMISSIVE and ON_PERMISSIVE were introduced in 5.7 in this worklog.
# BUG#20471216: 5.6 WITH GTID_MODE=X CANT CONNECT TO 5.7.6 WITH GTID_MODE=X_PERMISSIVE
# - 5.6 was fixed to accept ON_PERMISSIVE and OFF_PERMISSIVE in this bug.
