################################################################################
# ==== Purpose ====
# Test referential actions of the foreign keys with different
# binlog_transaction_dependency_tracking modes.
# Referential actions:
#  RESTRICT | NO ACTION | CASCADE | SET NULL | SET DEFAULT
#  Note* Table definition containing SET DEFAULT gets rejected thus not tested.
# Modes:
#  COMMIT_ORDER | WRITESET | WRITESET_SESSION
#  Note* COMMIT_ORDER is purposefully not tested with this test.
#
# ==== Implementation ====
# 1. FK parent table:
#    1.1. Marked as conflicting with previous transactions.
#    1.2. Clears history.
#    1.3. Marked as conflicting with later transactions.
#    1.4. Falls back to COMMIT_ORDER, so *not* marked as conflicting with previous transactions
#         committing in parallel.
#    1.5. Later transactions fall back to COMMIT_ORDER, so they are *not* marked as conflicting with
#         this transaction if executing in parallel with it.
#
# 2. FK child table:
#    2.1. Can run in parallel with previous transactions.
#    2.2. Does not clear history.
#    2.3. Can run in parallel with subsequent transactions.
#
# 3. All the above is tested with INSERT, UPDATE, and DELETEs.
#
# 4. All the above is tested with RESTRICT, NO ACTION, CASCADE, SET NULL.
#
# 5. All the above is tested with ON UPDATE and ON DELETE.
#
# 6. All the above is tested with WRITESET_SESSION and WRITESET.
