# ==== Purpose ====
#
# Test replication of transactions on tables which have different
# engines on master and slave.  This tests all combinations of innodb,
# myisam, and ndb.
#
# ==== Method ====
#
# Set up six tables, each being innodb, myisam, or innodb on master,
# and another of innodb, myisam, or innodb on slave.  For each table,
# do the following:
#
#  - committed and rollback'ed transactions, with autocommit on and
#    off
#  - non-transactions with autocommit on
#  - non-transactions with autocommit off, where the master table is
#    myisam.
#
# Note: we are running the slave with
# --replicate-ignore-table=mysql.ndb_apply_status .  See BUG#34557 for
# explanation.
#
# ==== Related bugs ====
#
# BUG#26395: if crash during autocommit update to transactional table on master, slave fails
# BUG#29288: myisam transactions replicated to a transactional slave leaves slave unstable
# BUG#34557: Row-based replication from ndb to non-ndb gives error on slave
# BUG#34600: Rolled-back punch transactions not replicated correctly
#
# ==== Todo ====
#
# We should eventually try transactions touching two tables which are
# of different engines on the same server (so that we try, e.g. punch
# transactions; cf BUG#34600).  However, that will make the test much
# bigger (9 master-slave engine combinations [myisam->myisam,
# myisam->ndb, etc].  To try all combinations of one or more such
# tables means 2^9-1=511 transactions.  We need to multiplied by 5
# since we want to test committed/rollback'ed transactions
# with/without AUTOCOMMIT, as well as non-transactions with
# autocommit).  We'd have to write a script to produce the test case.
