# BUG#42851: Spurious "Statement is not safe to log in statement
# format." warnings
#
# WHY
# ===
#
# This test aims at checking that the fix that removes spurious
# entries in the error log when the statement is filtered out from
# binlog, is working.
#
# HOW
# ===
#
# The test case is split into three assertions when issuing statements
# containing LIMIT and ORDER BY:
#
# i) issue statements in database that is not filtered => check
# that warnings ARE shown;
#
# ii) issue statements in database that is not filtered, but with
# binlog disabled => check that warnings ARE NOT shown;
#
# iii) issue statements in database that is filtered => check that
# warnings ARE NOT shown.
