There is an inconsistency with DROP DATABASE|TABLE|EVENT IF EXISTS and CREATE DATABASE|TABLE|EVENT IF NOT EXISTS. DROP IF EXISTS statements are binlogged even if either the DB, TABLE or EVENT does not exist. In contrast, Only the CREATE EVENT IF NOT EXISTS is binlogged when the EVENT exists. This patch fixes the following cases for all the replication formats: CREATE DATABASE IF NOT EXISTS. CREATE TABLE IF NOT EXISTS, CREATE TABLE IF NOT EXISTS ... LIKE, CREAET TABLE IF NOT EXISTS ... SELECT.

# BUG#45574:
|
|
# SP: CREATE DATABASE|TABLE IF NOT EXISTS not binlogged if routine exists.
|
|
#
|
|
# There is an inconsistency with DROP DATABASE|TABLE|EVENT IF EXISTS and
|
|
# CREATE DATABASE|TABLE|EVENT IF NOT EXISTS. DROP IF EXISTS statements are
|
|
# binlogged even if either the DB, TABLE or EVENT does not exist. In
|
|
# contrast, Only the CREATE EVENT IF NOT EXISTS is binlogged when the EVENT
|
|
# exists.
|
|
#
|
|
# This problem caused some of the tests to fail randomly on PB or PB2.
|
|
#
|
|
# Description:
|
|
# Fixed this bug by adding calls to write_bin_log in:
|
|
# mysql_create_db
|
|
# mysql_create_table_no_lock
|
|
# mysql_create_like_table
|
|
# create_table_from_items
|
|
#
|
|
# Test is implemented as follows:
|
|
# i) test each "CREATE IF NOT EXISTS" (DDL), found in MySQL 5.1 manual
|
|
# exclude CREATE TEMPORARY TABLE, on existent objects;
|
|
#
|
|
# Note:
|
|
# rpl_create_tmp_table_if_not_exists.test tests CREATE TEMPORARY TABLE cases.
