#
# This test suite checks the following statements:
# - SET <instance id>.<option name> = <option value>;
# - UNSET <instance id>.<option name> = <option value>;
# - FLUSH INSTANCES;
#
# For SET/UNSET we check that:
# - SET ignores spaces correctly;
# - UNSET does not allow option-value part (= <option value>);
# - SET/UNSET can be applied several times w/o error;
# - SET/UNSET is allowed only for stopped instances;
# - SET/UNSET updates both the configuration cache in IM and
# the configuration file;
#
# For FLUSH INSTANCES we check that:
# - FLUSH INSTANCES is allowed only when all instances are stopped;
#
# According to the IM implementation details, we should play at least with the
# following options:
# - server_id
# - port
# - nonguarded
#
# Let's test SET statement on the option 'server_id'. It's expected that
# originally the instances have the following server ids and states:
# - mysqld1: server_id: 1; running (online)
# - mysqld2: server_id: 2; stopped (offline)
#
# NOTE: each CREATE INSTANCE statement must specify socket-file-name, otherwise
# this results of the test can be affected by another running test suite.
