Alexey Botchkov	e99850774b	GIS library code cleanup. GCALC_DBUG_OFF and related infrastructure defined so we can enable/disable debugging conveniently. per-file comments: sql/gcalc_slicescan.cc GIS library code cleanup. sql/gcalc_slicescan.h GIS library code cleanup. sql/gcalc_tools.cc GIS library code cleanup. sql/gcalc_tools.h GIS library code cleanup.	14 years ago
Alexey Botchkov	6e7d578b2b	bug 857087 Wrong result with ST_INTERSECTS and LINESTRINGs Line autointersection point was treated as if it doesn't belong to the line. It's in some way logical, but seems to confuse people. Fixed. per_file_comments: mysql-test/r/gis-precise.result bug 857087 Wrong result with ST_INTERSECTS and LINESTRINGs test result updated. mysql-test/t/gis-precise.test bug 857087 Wrong result with ST_INTERSECTS and LINESTRINGs test case added. sql/gcalc_tools.cc bug 857087 Wrong result with ST_INTERSECTS and LINESTRINGs Point of line autointersection handled as it belongs to the line. sql/gcalc_tools.h bug 857087 Wrong result with ST_INTERSECTS and LINESTRINGs Gcalc_function::set_i_state() added	14 years ago
Alexey Botchkov	5123f59ed2	fixed bugs 855485 ST_CROSSES returns different result than PostGIS for overlapping polygons 855487 ST_WITHIN returns wrong result for partially overlapping polygons 855492 ST_WITHIN returns TRUE on point on the edge of a polygon 855497 ST_ENVELOPE of GEOMETRYCOLLECTION EMPTY returns NULL and not GEOMETRYCOLLECTION EMPTY 855503 ST_EQUALS reports TRUE between a POLYGON and a MULTILINESTRING 855505 ST_TOUCHES reports TRUE for intersecting polygon and linestring Changed the way weird functions like Crosses or Touches treated. Added BORDER handling to the Gcalc_function. per-file comments: mysql-test/r/gis-precise.result GIS bugs fixed. test result updated. mysql-test/t/gis-precise.test GIS bugs fixed. test cases added. sql/gcalc_slicescan.h GIS bugs fixed. sql/gcalc_tools.cc GIS bugs fixed. sql/gcalc_tools.h GIS bugs fixed. sql/item_create.cc GIS bugs fixed. sql/item_geofunc.cc GIS bugs fixed. sql/item_geofunc.h GIS bugs fixed. sql/spatial.cc GIS bugs fixed.	14 years ago

Alexey Botchkov	90c4df7a4a	Fix for bug #804266 Memory corruption/valgrind warning/crash in move_hole() with ST_UNION. Second smaller hole in the polygon got link to the bigger one as it's the outer ring. Fixed by specifying the outer ring explicitly. per-file comments: mysql-test/r/gis-precise.result Fix for bug #804266 Memory corruption/valgrind warning/crash in move_hole() with ST_UNION. test result updated. mysql-test/t/gis-precise.test Fix for bug #804266 Memory corruption/valgrind warning/crash in move_hole() with ST_UNION. test case added. sql/gcalc_tools.cc Fix for bug #804266 Memory corruption/valgrind warning/crash in move_hole() with ST_UNION. specify the outer ring explicitly in the get_polygon_result parameter. sql/gcalc_tools.h Fix for bug #804266 Memory corruption/valgrind warning/crash in move_hole() with ST_UNION. add the outer ring as a parameter to the get_polygon_result.	15 years ago
Alexey Botchkov	f3b850a7b5	bug #804305 Crash in wkb_get_double with ST_INTERSECTION. That crash happened with the complicated topology of the result. If we found a hole in a polygon whose outside border was already found, we need to paste the hole right after it and respectively shift polygons after it. Also we need to update poly_position fields in these polygons. That last thing wasn't properly done that led to the crash. To fix that we keep the list of the found polygons and update the poly_positions that are bigger or equal to where we placed the next hole. per-file comments: mysql-test/r/gis-precise.result bug #804305 Crash in wkb_get_double with ST_INTERSECTION. test result updated. mysql-test/t/gis-precise.test bug #804305 Crash in wkb_get_double with ST_INTERSECTION. test result added. sql/gcalc_tools.cc bug #804305 Crash in wkb_get_double with ST_INTERSECTION. keep the list of the found polygons and update their poly_position fields respectively. sql/gcalc_tools.h bug #804305 Crash in wkb_get_double with ST_INTERSECTION. Gcalc_result_receiver::move_hole interface changed.	15 years ago
