# 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.
