Set the default to be mrr=off,mrr_sort_keys=off: - 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 2011-07-08 16:46:47 +02:00

Change the default @@optimizer_switch setting from semijoin=on,firstmatch=on,loosescan=on to semijoin=off,firstmatch=off,loosescan=off Adjust the testcases: - Modify subselect*.test and join_cache.test so that all tests use the same execution paths as before (i.e. optimizations that are being tested are enabled) - Let all other test files run with the new default settings (i.e. with new optimizations disabled) - Copy subquery testcases from these files into t/subselect_extra.test which will run them with new optimizations enabled. 2011-07-04 23:44:15 +02:00			`set @optimizer_switch_for_subselect_test=null;`
