# 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.
