# Bug#17942050:KILL OF TRUNCATE TABLE WILL LEAD TO BINARY LOG WRITTEN WHILE
|
|
# ROWS REMAINS
|
|
#
|
|
# Problem:
|
|
# ========
|
|
# When truncate table fails while using transactional based engines even
|
|
# though the operation errors out we still continue and log it to binlog.
|
|
# Because of this master has data but the truncate will be written to binary
|
|
# log which will cause inconsistency.
|
|
#
|
|
# Test:
|
|
# =====
|
|
# Make master to wait in "open_table" call during the execution of truncate
|
|
# table command and kill the truncate table from other connection. This causes
|
|
# open table to return an error saying truncate failed during open table. This
|
|
# statement should not be binlogged.
