#########################################
# ==== Purpose ====
#
# Test binlog replaying binlogs for CREATE TABLE ... AS SELECT (DDL_CTAS)
# from the output of mysqlbinlog tool.
#
# ==== Requirements ====
#
# R1 Test binlog replay for DDL_CTAS.
#
# R2 Test crash during binlog replay for DDL_CTAS causes transaction recovery.
#
# R3 Replay DDL_CTAS with rows and then force rollback.
#
# R4 Repeat R2 with DDL_CTAS executed from within procedure.
#
# R5 Repeat R2 with DDL_CTAS executed using prepared statement.
#
# ==== Implementation ====
#
# TC1: Replay DDL_CTAS without rows and also crash before commit.
# 1) Create table t0 and Execute DDL_CTAS.
# 2) Run mysqlbinlog tool and generate mysqlbinlog.sql.
# 3) Drop table t0 and t1;
# 4) Replay the binlogs in mysqlbinlog.sql.
# 5) Verify that we have both t0 and t1 tables created.
# 6) Drop table t0 and t1 again.
# 7) Enable debug point to induce crash before commit.
# 8) Replay the binlogs in mysqlbinlog.sql, which causes crash.
# 9) Wait until server stops completely and then restart the server.
# 10) Verify that table t0 exists and t1 does not exists.
# 11) Drop the table t0.
# 12) And reset debug flag.
#
# TC2: Replay DDL_CTAS with rows and also crash before commit.
# Repeat steps from TC1 with rows inserted in t0.
#
# TC3: Replay DDL_CTAS with rows and then force rollback.
# Repeat steps from TC1 with rows inserted in t0. Verify that we have
# only t0 after rollback.
#
# TC4: Replay DDL_CTAS without rows and also crash before commit.
# Repeat steps from TC1 with a stored procedure executing DDL_CTAS.
#
# TC5: Replay DDL_CTAS with rows and also crash before commit.
# Repeat steps from TC1 with few rows inserted in t0 and a stored procedure
# executing DDL_CTAS.
#
# TC6: Replay DDL_CTAS with rows and also crash before commit.
# Repeat steps from TC1 with few rows inserted in t0 and a stored procedure
# executing DDL_CTAS.
#
