Bug#17877 - Corrupted spatial index
CHECK TABLE could complain about a fully intact spatial index.
A wrong comparison operator was used for table checking.
The result was that it checked for non-matching spatial keys.
This succeeded if at least two different keys were present,
but failed if only the matching key was present.
I fixed the key comparison.
myisam/mi_check.c:
Bug#17877 - Corrupted spatial index
Fixed the comparison operator for checking a spatial index.
Using MBR_EQUAL | MBR_DATA to compare for equality and
include the data pointer in the comparison. The latter
finds the index entry that points to the current record.
This is necessary for non-unique indexes.
The old operator, SEARCH_SAME, is unknown to the rtree
search functions and handled like MBR_DISJOINT.
myisam/mi_key.c:
Bug#17877 - Corrupted spatial index
Added a missing DBUG_RETURN.
myisam/rt_index.c:
Bug#17877 - Corrupted spatial index
Included the data pointer in the copy of the search key.
This is necessary for searching the index entry that points
to a specific record if the search_flag contains MBR_DATA.
myisam/rt_mbr.c:
Bug#17877 - Corrupted spatial index
Extended the RT_CMP() macro with an assert for an
unexpected comparison operator.
mysql-test/r/gis-rtree.result:
Bug#17877 - Corrupted spatial index
The test result.
mysql-test/t/gis-rtree.test:
Bug#17877 - Corrupted spatial index
The test case.
