- Set the default - Adjust the testcases so that 'new' tests are run with optimizations turned on. - Pull out relevant tests from "irrelevant" tests and run them with optimizations on. - Run range.test and innodb.test with both mrr=on and mrr=off

# BUG#711565 Index Condition Pushdown can make a thread hold MyISAM locks as well as be unKILLable for long time
|
|
# This is not a ready mysqltest testcase but rather a set of queries that
|
|
# allow to check the bug[fix] manually. Making this testcase automatic is
|
|
# difficult because
|
|
# - big tables are involved
|
|
# - it's difficult to have automatic checks of whether the query could be
|
|
# KILLed that would reliably work on fast/slow buildslaves, etc.
