WL#11703: Migrate optimizer tests from main suite to run with default engine innodb (subquery)
Affects: Server-8.0
—
Status: Complete
In latest releases , innodb is made as default engine. But tests from main
suite are written considering myisam as engine from start. As count of tests
from
main suite is , so modifications (tests and/or result) for innodb is big task.
We currently continue to run main suite test with "myisam" by calling
"include/force_myisam_default.inc" .
So as to make test run with innodb we have to adjust test(and/or result) and
remove "include/force_myisam_default.inc" from each test.
This WL targets changing optimizer related test (where tests are failing mainly
due to difference in explain output )when run with innodb as default engine.
Difference in explain output is for
- index used
- rows ( which vary for innodb)
- Comment field
**List of test which have failure/result difference related to optimizer (they
might have additional difference too )
