Multi-table delete that is optimized with QUICK_RANGE reports table
corruption.
DELETE statement must not use KEYREAD optimization, and sets
table->no_keyread to 1. This was ignored in QUICK_RANGE optimization.
With this fix QUICK_RANGE optimization honors table->no_keyread
value and does not enable KEYREAD when it is requested.
are not specified in an insert. Most of these changes are actually to
clean up the test suite to either specify defaults to avoid warnings,
or add the warnings to the results. Related to bug #5986.
* Fixed a problem with wrong query results for partially covering keys in ROR-index_merge
* ROR-intersection retrieval plan choice algorithm now uses less disk IO
- and properly processes clustered PK range scans
* Fixed several minor range optimizer problems
* Added more comments
* Code cleanup
