# BUG#13684:
# SP: DROP PROCEDURE|FUNCTION IF EXISTS not binlogged if routine
# does not exist
#
# There is an inconsistency with DROP DATABASE IF EXISTS, DROP
# TABLE IF EXISTS and DROP VIEW IF EXISTS: those are binlogged even
# if the DB or TABLE does not exist, whereas DROP PROCEDURE IF
# EXISTS does not. It would be nice or at least consistent if DROP
# PROCEDURE/STATEMENT worked the same too.
#
# Description:
# DROP PROCEDURE|FUNCTION IF EXISTS does not get binlogged whereas DROP
# DATABASE|TABLE|TRIGGER|... IF EXISTS do.
#
# Fixed DROP PROCEDURE|FUNCTION IF EXISTS by adding a call to
# write_bin_log in mysql_execute_command. Checked also if all
# documented "DROP (...) IF EXISTS" get binlogged. Left out DROP
# SERVER IF EXISTS because it seems that it only gets binlogged when
# using row event (see BUG#25705).
#
# TODO: add DROP SERVER IF EXISTS to the test case when its
# binlogging procedure gets fixed (BUG#25705). Furthermore, when
# logging in RBR format the events that get logged are effectively in
# RBR format and not in STATEMENT format meaning that one must needs
# to be extra careful when writing a test for it, or change the CREATE
# SERVER logging to always log as STATEMENT. You can quickly check this
# by enabling the flag below $fixed_bug_25705=1 and watch the diff on
# the STDOUT. More detail may be found on the generated reject file.
#
# Test is implemented as follows:
#
# i) test each "drop if exists" (DDL), found in MySQL 5.1 manual,
# on inexistent objects (except for DROP SERVER);
# ii) show binlog events;
# iii) create an object for each drop if exists statement;
# iv) issue "drop if exists" in existent objects.
# v) show binlog events;
