# ==== Purpose ====
# Prove successful server recovery after simulated crash while
# there were recoverable DDL queries in processing.
# The recoverable DDL:s are those that are binary-logged with xid info
# with enables the server to decide on their commit or rollback at server
# recovery.
#
# ==== Implementation ====
#
# The test consists of two part. In the first major part
# it verifies the server recovery for each recoverable DDL query.
# A client connection issues a DDL query whose processing either completes
# is interrupted by simulated crash either at time the DDL has been
# already prepared in the engine and binary-logged, or just prepared
# and not yet logged.
# Upon the server restart the query execution status is checked, and
# the check outcome must correspond to timing of the crash. The logged
# query's result must be committed, and not-logged are to be rolled
# back by the server recovery.
# The 2nd minor part proves correct mysqlbinlog processing.
#
