#  WL#5096
#  
#  Description 
#  ===========
#
#  This test case covers Requirements for replication using different
#  combinations of indexes and blob fields. 
#
#  It acts as a complement for rpl_row_img_sanity tests as it checks
#  that in a chained replication scenario, replication does not break.
#
#  Usage
#  =====
#
#  Before including this file the following variables should be set:
#    * $server_1_engine
#    * $server_2_engine
#    * $server_3_engine
#
#  Example:
#
#     -- let $server_1_engine= Falcon
#     -- let $server_2_engine= MyISAM
#     -- let $server_3_engine= InnoDB
#
#     -- source extra/rpl_tests/rpl_row_img_blobs.test
# 

-- connection server_1

-- let $diff_table=test.t
let $i= 7;
while($i)
{
  -- connection server_1
  SET SQL_LOG_BIN=0;

  -- connection server_2
  SET SQL_LOG_BIN=0;

  -- connection server_3
  SET SQL_LOG_BIN=0;

  # 
  # The comments below (on create table) must be read with the SQL
  # instructions issued later in mind. Declaring a table obviously is 
  # not enough to assert anything.
  #
  # Also, the tests in this file make more sense when performed with
  # binlog_row_image configured as NOBLOB.
