#
# This is an include file that performs some assertions
# on behalf of rpl_row_img_sanity test case.
#
# It begins by dumping the current connection binary log
# and then compares it against the expected values (which
# are parameters to this include)
#
# Expected values are arguments to this script and must be structured
# as follows:
#
# -- let $row_img_expected= 1:1 2:2 3:'a' 4:NULL | 1:2 4:10
#
# This example means that BEFORE IMAGE contains values for columns
# with the given index in the original table 1, 2, 3, 4 and their
# values are 1,2,'a',NULL respectively.
#
# The same resoning for the AFTER IMAGE that follows the image
# separator char '|'.
#
# Arguments:
#
# - $row_img_expected
# The expected values for BI and AI that we are searching for
# - $row_img_pos
# The start position in the binary log from which the searching
# will be done
#
# Sample usage:
#
# -- let $row_img_expected= 1:1 2:2 3:'a' 4:NULL | 1:2 4:10
# -- let $row_img_pos= 107
# -- source include/rpl_row_img_parts_assertion.inc
#
