# include/concurrent.inc
#
# Concurrent tests for transactional storage engines, mainly in UPDATE's
# Bug#3300
# Designed and tested by Sinisa Milivojevic, sinisa@mysql.com
#
# two non-interfering UPDATE's not changing result set
#
# The variable
#     $engine_type       -- storage engine to be tested
# has to be set before sourcing this script.
#
# Last update:
# 2006-08-02 ML test refactored
#               old name was t/innodb_concurrent.test
#               main code went into include/concurrent.inc
