+# 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;
