# This test verifies if the server migrates correctly from a file repository to a
# table repository and vice-versa. In particular, it checks if the information in the
# relay log info is correctly migrated between the different types (i.e. FILE or TABLE)
# of repositories. The algorithm and the function used to migrate the master info is
# the same and for that reason, we do not test its migration.
#
# If a FILE repository is used, the following assertions are valid:
# AF1. SELECT COUNT(*) FROM mysql.slave_relay_log_info == 0
# AF2. file_exists $MYSQLD_DATADIR/relay-log.info == 1
#
# If a TABLE repository is used, the following assertions are valid:
# AT1. SELECT COUNT(*) FROM mysql.slave_relay_log_info == 1
# AT2. file_exists $MYSQLD_DATADIR/relay-log.info == 0
#
# The test case is organized as follows:
#
# 1. Preparation:
# 1.1. The slave is started with a FILE repository enabled and the replication
# stopped.
# 1.2. A table is created and populated in order to check at the end of the test
# if data is replicated correctly.
# 1.3. Assertions AF1 and AF2 are verified.
#
# 2. Migration from FILE to TABLE by restarting the SERVER
# 2.1. The slave is stopped and restarted with --relay-log-info-repository=TABLE
# 2.2. Assertions AT1 and AT2 are verified.
#
# 3. Migration from TABLE to FILE by restarting the SERVER
# 4.1. The slave is stopped and restarted with --relay-log-info-repository=FILE
# 4.2. Assertions AF1 and AF2 are verified.
#
# 4. Migration from FILE to TALBE by using SET
# 4.1. SET @GLOBAL.relay_log_info_repository=TABLE is exectued.
# 4.2. Assertions AT1 and AT2 are verified.
#
# 5. Migration from TABLE to FILE by using SET
# 5.1. SET @GLOBAL.relay_log_info_repository=FILE is executed.
# 5.2. Assertions AF1 and AF2 are verified.
#
# 6. Migration from FILE to FILE by using SET
# 6.1. SET @GLOBAL.relay_log_info_repository=FILE is executed.
# 6.2. Assertions AF1 and AF2 are verified.
#
# 7. Migration while slave is running by using SET
# 7.1 Slave is started.
# 7.2. SET @GLOBAL.relay_log_info_repository=FILE is executed and fails.
# 7.3. Assertions AF1 and AF2 are verified.
#
# 8. Check consistency
# 8.1. The replication is started and the master is compared to the slave.
