Bug#35931 Index search of partitioned MyISAM table
returns erroneous results Used the wrong function when fixing 30480 which lead to no stop on end_key resulting in duplicate results from index scan Includes test cases for the duplicates 37327 and 37329, Duplicate rows and bad performance/High Handler_read_next values Recommit after merge issues
