--echo # Bug #22284224: REWRITE REPOPULATION OF CHARACTER SETS AND COLLATIONS DURING STARTUP
--echo #
--echo # Verify that new collations become available in the server
--echo # after a restart. Verify that previously existing
--echo # collations are deleted if they are not present in the
--echo # character sets dir when restarting.

--echo #
--echo # New character sets dir:
--replace_result $MYSQL_TEST_DIR MYSQL_TEST_DIR
SHOW VARIABLES LIKE 'character_sets_dir%';

--echo #
--echo # Show new collation available in the new character sets dir:
SHOW COLLATION LIKE 'utf8_phone_ci';

--echo #
--echo # Create and drop a table using the new collation:
CREATE TABLE t1 (pk INTEGER) COLLATE utf8_phone_ci;
SHOW CREATE TABLE t1;
DROP TABLE t1;

--echo #
--echo # Restart server with original character sets dir:
--let $restart_parameters=restart:--character-sets-dir=$MYSQL_CHARSETSDIR
--replace_result $MYSQL_CHARSETSDIR MYSQL_CHARSETSDIR
--source include/restart_mysqld.inc

--echo #
--echo # Reverted to old character sets dir:
--replace_result $MYSQL_CHARSETSDIR MYSQL_CHARSETSDIR
SHOW VARIABLES LIKE 'character_sets_dir%';

--echo #
--echo # The newly added collation has been deleted:
SHOW COLLATION LIKE 'utf8_phone_ci';

--echo #
--echo # Create a table using the deleted collation, expected to fail:
--error ER_UNKNOWN_COLLATION
CREATE TABLE t1 (pk INTEGER) COLLATE utf8_phone_ci;
