(This is attempt at fix#2) (re-commit with fixed typo)
- Moved the testcase from partition_test to partition_innodb.test where it can really work.
- Made ordered index scans over ha_partition tables to satisfy ROR property for
the case where underlying table uses extended keys.
MDEV-5555: Incorrect index_merge on BTREE indices
- In ha_partition, make ordered index reads return rows in rowid order
when index columns are the same.
mysql-test/r/partition_order.result:
Changed a test case to handle ordered index scan reverse order as well
mysql-test/t/partition_order.test:
Changed a test case to handle ordered index scan reverse order as well
sql/ha_myisam.cc:
More debug info
sql/ha_partition.cc:
Introduced partition_index_read_last to ensure we use index_read_last in those
cases towards underlying handler.
Ensured that index_read with HA_READ_PREFIX_LAST, HA_READ_PREFIX_LAST_OR_PREV and
HA_READ_BEFORE_KEY uses ordered index scan in reverse order.
