From 24885e815f3309229334884d2d2b9d065ede3807 Mon Sep 17 00:00:00 2001 From: Ramil Kalimullin <ramil@mysql.com> Date: Fri, 23 Oct 2009 16:26:48 +0500 Subject: [PATCH] Fix for bug#48258: Assertion failed when using a spatial index Problem: involving a spatial index for "non-spatial" queries (that don't containt MBRXXX() functions) may lead to failed assert. Fix: don't use spatial indexes in such cases. --- mysql-test/r/gis-rtree.result | 39 +++++++++++++++++++++++++++++++++++ mysql-test/t/gis-rtree.test | 21 +++++++++++++++++++ sql/opt_range.cc | 21 +++++++++++++++++++ 3 files changed, 81 insertions(+) diff --git a/mysql-test/r/gis-rtree.result b/mysql-test/r/gis-rtree.result index a4fa929c32..165db88289 100644 --- a/mysql-test/r/gis-rtree.result +++ b/mysql-test/r/gis-rtree.result @@ -1487,4 +1487,43 @@ MBRINTERSECTS(b, GEOMFROMTEXT('LINESTRING(1 1,1102219 2)') ); COUNT(*) 2 DROP TABLE t1; +# +# Bug #48258: Assertion failed when using a spatial index +# +CREATE TABLE t1(a LINESTRING NOT NULL, SPATIAL KEY(a)); +INSERT INTO t1 VALUES +(GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)')), +(GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)')); +EXPLAIN SELECT 1 FROM t1 WHERE a = GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)'); +id select_type table type possible_keys key key_len ref rows Extra +1 SIMPLE t1 ALL a NULL NULL NULL 2 Using where +SELECT 1 FROM t1 WHERE a = GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)'); +1 +1 +1 +EXPLAIN SELECT 1 FROM t1 WHERE a < GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)'); +id select_type table type possible_keys key key_len ref rows Extra +1 SIMPLE t1 ALL a NULL NULL NULL 2 Using where +SELECT 1 FROM t1 WHERE a < GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)'); +1 +EXPLAIN SELECT 1 FROM t1 WHERE a <= GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)'); +id select_type table type possible_keys key key_len ref rows Extra +1 SIMPLE t1 ALL a NULL NULL NULL 2 Using where +SELECT 1 FROM t1 WHERE a <= GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)'); +1 +1 +1 +EXPLAIN SELECT 1 FROM t1 WHERE a > GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)'); +id select_type table type possible_keys key key_len ref rows Extra +1 SIMPLE t1 ALL a NULL NULL NULL 2 Using where +SELECT 1 FROM t1 WHERE a > GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)'); +1 +EXPLAIN SELECT 1 FROM t1 WHERE a >= GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)'); +id select_type table type possible_keys key key_len ref rows Extra +1 SIMPLE t1 ALL a NULL NULL NULL 2 Using where +SELECT 1 FROM t1 WHERE a >= GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)'); +1 +1 +1 +DROP TABLE t1; End of 5.0 tests. diff --git a/mysql-test/t/gis-rtree.test b/mysql-test/t/gis-rtree.test index 2c1632f8d4..b5de1ccf24 100644 --- a/mysql-test/t/gis-rtree.test +++ b/mysql-test/t/gis-rtree.test @@ -881,4 +881,25 @@ SELECT COUNT(*) FROM t1 IGNORE INDEX (b) WHERE DROP TABLE t1; + +--echo # +--echo # Bug #48258: Assertion failed when using a spatial index +--echo # +CREATE TABLE t1(a LINESTRING NOT NULL, SPATIAL KEY(a)); +INSERT INTO t1 VALUES + (GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)')), + (GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)')); +EXPLAIN SELECT 1 FROM t1 WHERE a = GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)'); +SELECT 1 FROM t1 WHERE a = GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)'); +EXPLAIN SELECT 1 FROM t1 WHERE a < GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)'); +SELECT 1 FROM t1 WHERE a < GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)'); +EXPLAIN SELECT 1 FROM t1 WHERE a <= GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)'); +SELECT 1 FROM t1 WHERE a <= GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)'); +EXPLAIN SELECT 1 FROM t1 WHERE a > GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)'); +SELECT 1 FROM t1 WHERE a > GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)'); +EXPLAIN SELECT 1 FROM t1 WHERE a >= GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)'); +SELECT 1 FROM t1 WHERE a >= GEOMFROMTEXT('LINESTRING(-1 -1, 1 -1, -1 -1, -1 1, 1 1)'); +DROP TABLE t1; + + --echo End of 5.0 tests. diff --git a/sql/opt_range.cc b/sql/opt_range.cc index 355317fe28..3236ccd2cf 100644 --- a/sql/opt_range.cc +++ b/sql/opt_range.cc @@ -4377,6 +4377,27 @@ get_mm_leaf(PARAM *param, COND *conf_func, Field *field, KEY_PART *key_part, !(conf_func->compare_collation()->state & MY_CS_BINSORT)) goto end; + if (key_part->image_type == Field::itMBR) + { + switch (type) { + case Item_func::SP_EQUALS_FUNC: + case Item_func::SP_DISJOINT_FUNC: + case Item_func::SP_INTERSECTS_FUNC: + case Item_func::SP_TOUCHES_FUNC: + case Item_func::SP_CROSSES_FUNC: + case Item_func::SP_WITHIN_FUNC: + case Item_func::SP_CONTAINS_FUNC: + case Item_func::SP_OVERLAPS_FUNC: + break; + default: + /* + We cannot involve spatial indexes for queries that + don't use MBREQUALS(), MBRDISJOINT(), etc. functions. + */ + goto end; + } + } + optimize_range= field->optimize_range(param->real_keynr[key_part->key], key_part->part); -- 2.30.9
