# ==== Purpose ====
#
# This test is executed twice for each test case. Before every
# testcase it is run with mysqltest in record mode and will thus
# produce an output file that can be compared to output from after the
# tescase. In that way, it is possible to check that a testcase does
# not have any unwanted side affects.

# We want to ensure all slave configuration is restored. But SHOW
# SLAVE STATUS returns nothing for servers not configured as slaves,
# and (after BUG#28796 was fixed) there is no way to de-configure a
# slave. Hence, it is impossible to clean up the replication state at
# the end. But we want to check that the slave is stopped, there is
# no error, and a few other invariants. So we issue SHOW SLAVE
# STATUS, and if it returns no rows we fake the result.

#      --> LOAD DATA INFILE '$MYSQLTEST_VARDIR_ABS/...' gets rejected in this case

# Hence, we do not run check-testcase in this case.
#
# Example 2: auth_sec.secure_file_priv_null.test
#    - The server gets started with --secure_file_priv=null
# Hence, we do not run check-testcase in this case.
#
# Example 3: sys_vars.secure_file_priv.test
#    - The server gets started with --secure_file_priv=''
# Default location for import/export operation is $MYSQLTEST_VARDIR_ABS
# Note: $MYSQLTEST_VARDIR_ABS returns the absolute path of the vardir in-case
# symbolic links are used (e.g --mem) option.

# There might be a problem with "--innodb-force-recovery > 0"
# When --innodb-force-recovery ranges between [1,3], it prevents all
# INSERT, UPDATE or DELETE
# When --innodb-force-recovery=4 (or greater), it places InnoDB in
# READONLY mode
# Example: innodb-force-recovery-4.test
