# The variable
#     $engine_type       -- storage engine to be tested
# has to be set before sourcing this script.
#
# Notes:
# 1. This test uses at least in case of InnoDB options
#     innodb_locks_unsafe_for_binlog = true
#     innodb_lock_timeout = 5
# 2. The comments/expectations refer to InnoDB.
#    They might be not valid for other storage engines.
#
# Last update:
# 2006-08-02 ML test refactored
#               old name was innodb_unsafe_binlog.test
#               main code went into include/unsafe_binlog.inc
