# ==== Purpose ====
#
# Verify that the log_statements_unsafe_for_binlog system variable works
#
# ==== Method ====
#
# 1. Turn on log_statements_unsafe_for_binlog
# 2. Run unsafe statement
# 3. Verify error log contains warning
# 4. Turn off log_statements_unsafe_for_binlog
# 5. Run unsafe statement
# 6. Verify error log still contains only one warning
#
# ==== References ====
#
# WL#8993: Option to not log in the error log when unsafe statements are executed whilst using STATEMENT based binary logging

# As this test file will check for information on the error log, we will
# restart the server to make sure that the log contains an "startup" log
# message to be used as starting point for the grep.
