# 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
#   mysql_bin_log.write in mysql_execute_command. Checked also if all
#   documented "DROP (...) IF EXISTS" get binlogged. 
#
#   Test is implemented as follows:
#
#       i) test each "drop if exists" (DDL)
#      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;
