# DDL statements (sometimes with implicit COMMIT) executed   #
# by the master and it's propagation into the slave          #

#
# NOTE, PLEASE BE CAREFUL, WHEN MODIFYING THE TESTS !!
#
#      1. !All! objects to be dropped, renamed, altered ... must be created
#         in AUTOCOMMIT= 1 mode before AUTOCOMMIT is set to 0 and the test
#         sequences start.
#
#      2. Never use a test object, which was direct or indirect affected by a
#         preceeding test sequence again.
#         Except table d1.t1 where ONLY DML is allowed.
#
#         If one preceeding test sequence hits a (sometimes not good visible,
#         because the sql error code of the statement might be 0) bug
#         and these rules are ignored, a following test sequence might earn ugly
#         effects like failing 'sync_slave_with_master', crashes of the slave or
#         abort of the test case etc..
#
#      3. The assignment of the DDL command to be tested to $my_stmt can
#         be a bit difficult. "'" must be avoided, because the test
#         routine "include/rpl_stmt_seq.inc" performs a
#         eval SELECT CONCAT('######## ','$my_stmt','  ########') as "";
