From 0a91c7ccca2e78c419436c660eb99612e4e2b8a4 Mon Sep 17 00:00:00 2001 From: "evgen@moonbone.local" <> Date: Wed, 6 Jun 2007 00:25:06 +0400 Subject: [PATCH 01/20] Bug#28778: Wrong result of BETWEEN when comparing a DATETIME field with an integer constants. This bug is introduced by the fix for bug#16377. Before the fix the Item_func_between::fix_length_and_dec method converted the second and third arguments to the type of the first argument if they were constant and the first argument is of the DATE/DATETIME type. That approach worked well for integer constants and sometimes produced bad result for string constants. The fix for the bug#16377 wrongly removed that code at all and as a result of this the comparison of a DATETIME field and an integer constant was carried out in a wrong way and sometimes led to wrong result sets. Now the Item_func_between::fix_length_and_dec method converts the second and third arguments to the type of the first argument if they are constant, the first argument is of the DATE/DATETIME type and the DATETIME comparator isn't applicable. --- mysql-test/r/type_datetime.result | 16 ++++++++++++++++ mysql-test/t/type_datetime.test | 11 +++++++++++ sql/item_cmpfunc.cc | 17 +++++++++++++++++ 3 files changed, 44 insertions(+) diff --git a/mysql-test/r/type_datetime.result b/mysql-test/r/type_datetime.result index ba02f19712a..9e47b5da2b6 100644 --- a/mysql-test/r/type_datetime.result +++ b/mysql-test/r/type_datetime.result @@ -411,3 +411,19 @@ if(@bug28261 = f1, '', @bug28261:= f1) 2001-01-01 2002-02-02 drop table t1;

This bug was introduced by the fix for the bug#27300. In this fix a section of code was added to the Item::tmp_table_field_from_field_type method. This section intended to create Field_geom fields for the Item_geometry_func class and its descendants. In order to get the geometry type of the current item it casted "this" to the Item_geometry_func* type. But the Item::tmp_table_field_from_field_type method is also used for creation of fields for UNION and in this case this method is called for an object of the Item_type_holder class and the cast to the Item_geometry_func* type causes a server crash. Now the Item::tmp_table_field_from_field_type method correctly works when it's called for both the Item_type_holder and the Item_geometry_func classes. The new geometry_type variable is added to the Item_type_holder class. The new method called get_geometry_type is added to the Item_field and the Field classes. It returns geometry type from the field for the Item_field and the Field_geom classes and fails an assert for other Field descendants. --- mysql-test/r/gis.result | 21 +++++++++++++++++++++ mysql-test/t/gis.test | 13 +++++++++++++ sql/field.h | 7 ++++++- sql/item.cc | 8 +++++++- sql/item.h | 7 +++++++ 5 files changed, 54 insertions(+), 2 deletions(-) diff --git a/mysql-test/r/gis.result b/mysql-test/r/gis.result index 73e5b054f80..d1f292cda0c 100644 --- a/mysql-test/r/gis.result +++ b/mysql-test/r/gis.result @@ -864,4 +864,25 @@ SELECT Overlaps(@horiz1, @point2) FROM DUAL; Overlaps(@horiz1, @point2) 0 DROP TABLE t1; +create table t1(f1 geometry, f2 point, f3 linestring); +select f1 from t1 union select f1 from t1; +f1 +insert into t1 (f2,f3) values (GeomFromText('POINT(1 1)'), +GeomFromText('LINESTRING(0 0,1 1,2 2)')); +select AsText(f2),AsText(f3) from t1; +AsText(f2) AsText(f3) +POINT(1 1) LINESTRING(0 0,1 1,2 2) +select AsText(a) from (select f2 as a from t1 union select f3 from t1) t; +AsText(a) +POINT(1 1) +LINESTRING(0 0,1 1,2 2) +create table t2 as select f2 as a from t1 union select f3 from t1; +desc t2; +Field Type Null Key Default Extra +a point YES NULL +select AsText(a) from t2; +AsText(a) +POINT(1 1) +LINESTRING(0 0,1 1,2 2) +drop table t1, t2; End of 5.0 tests diff --git a/mysql-test/t/gis.test b/mysql-test/t/gis.test index ccc38db8dea..95ccc6272e2 100644 --- a/mysql-test/t/gis.test +++ b/mysql-test/t/gis.test @@ -557,4 +557,17 @@ SELECT Overlaps(@horiz1, @point2) FROM DUAL; DROP TABLE t1; +# +# Bug#28763: Selecting geometry fields in UNION caused server crash. +# +create table t1(f1 geometry, f2 point, f3 linestring); +select f1 from t1 union select f1 from t1; +insert into t1 (f2,f3) values (GeomFromText('POINT(1 1)'), + GeomFromText('LINESTRING(0 0,1 1,2 2)')); +select AsText(f2),AsText(f3) from t1; +select AsText(a) from (select f2 as a from t1 union select f3 from t1) t; +create table t2 as select f2 as a from t1 union select f3 from t1; +desc t2; +select AsText(a) from t2; +drop table t1, t2; --echo End of 5.0 tests diff --git a/sql/field.h b/sql/field.h index 37ce6b88453..39378addd4c 100644 --- a/sql/field.h +++ b/sql/field.h @@ -360,7 +360,11 @@ public: { return field_length / charset()->mbmaxlen; } - + virtual geometry_type get_geometry_type() + { + /* shouldn't get here. */ + DBUG_ASSERT(0); + } friend bool reopen_table(THD *,struct st_table *,bool); friend int cre_myisam(my_string name, register TABLE *form, uint options, ulonglong auto_increment_value); @@ -1325,6 +1329,7 @@ public: uint get_key_image(char *buff,uint length,imagetype type); uint size_of() const { return sizeof(*this); } int reset(void) { return !maybe_null() || Field_blob::reset(); } + geometry_type get_geometry_type() { return geom_type; }; }; #endif /*HAVE_SPATIAL*/ diff --git a/sql/item.cc b/sql/item.cc index 92ea35072f9..59708afdd19 100644 --- a/sql/item.cc +++ b/sql/item.cc @@ -4317,7 +4317,9 @@ Field *Item::tmp_table_field_from_field_type(TABLE *table) case MYSQL_TYPE_GEOMETRY: return new Field_geom(max_length, maybe_null, name, table, (Field::geometry_type) - ((Item_geometry_func *)this)->get_geometry_type()); + ((type() == Item::TYPE_HOLDER) ?

This path should not be modified because of lower_case_table_names as it is already in the correct case according to that setting. Fixed by removing the lowercasing.
