# ==== Purpose ====
|
|
# 2pc-aware DDL Query-log-event binlog event generator to be sourced from
|
|
# top-level files, e.g suite/binlog/t/binlog_half_crash_safe_ddl.test
|
|
# The file contains DDLs that are not fully crash-safe
|
|
# which include at this point general DDL:s like CREATE|DROP|ALTER table.
|
|
# See binlog_ddl.inc for the fully atomic ddl list.
|
|
#
|
|
# TODO: Fully-atomic reading statements could be migrated into binlog_ddl.inc
|
|
#
|
|
# ==== Implementation ====
|
|
# See comments in suite/binlog/t/binlog_half_crash_safe_ddl.test
|
|
|
|
# The result file records content of the binary log which in particular demonstrates
|
|
# xid field is in there.
