# MDEV-33064: ALTER INPLACE running TOI should abort a conflicting DML operation
#
# DDL operations may commit InnoDB transactions more than once during the execution.
# In this case wsrep flag on trx object is cleared, which may cause wrong logic of
# such operations afterwards (wsrep-related hooks are not run).
# One of the consequences was that DDL operation couldn't abort a DML operation
# holding conflicting locks.
#
# The fix: re-enable wsrep flag on trx restart if it's a part of a DDL operation.
