Alexey Botchkov	fc9d34cabf	bug #901655 ST_BUFFER asserts with a coplicated shape. Coinciding nodes can appear as a result of DOUBLE inaccuracy. We should test that before we start the loop. Also the spatial relations can be calculated faster if we check MBR relations first. And we do have the shape's MBR-s now. per-file comments: sql/gcalc_slicescan.cc set_extent() method added. bug #901655 ST_BUFFER asserts with a coplicated shape. sql/gcalc_slicescan.h set_extent() method declared. bug #901655 ST_BUFFER asserts with a coplicated shape. sql/gcalc_tools.cc bug #901655 ST_BUFFER asserts with a coplicated shape. checks for equal nodes added. sql/item_geofunc.cc bug #901655 ST_BUFFER asserts with a coplicated shape. MBR for the shapes calculated, and MBR checks added before we start the heavy calculations. sql/spatial.h bug #901655 ST_BUFFER asserts with a coplicated shape. MBR::buffer() method implemented.	14 years ago

Alexey Botchkov	0249413a6a	several bugs fixed here. 849789 Second assertion `m_poly_borders->next' failed in Gcalc_operation_reducer::count_slice in maria-5.3-gis 849791 Fourth assertion `n > 0 && n < SINUSES_CALCULATED*2+1' in get_n_sincos 849789 Second assertion `m_poly_borders->next' failed in Gcalc_operation_reducer::count_slice in maria-5.3-gis 848901 Assertion `fabs(cur_isc->x-m_cur_intersection->x) + fabs(cur_isc->y-m_cur_intersection->y) < 0.000000000001' failed in Gcalc_scan_iterator::intersection_scan() in maria-5.3-gis per-file comments: mysql-test/r/gis-precise.result test result updated. mysql-test/r/gis.result test result updated. sql/gcalc_slicescan.cc bugfixes. sql/gcalc_slicescan.h bugfixes. sql/gcalc_tools.cc bugfixes. sql/gcalc_tools.h bugfixes. sql/item_geofunc.cc bugfixes. sql/spatial.cc bugfixes.	14 years ago
Alexey Botchkov	3882c5d62c	Fix for few similar bugs: #841622 Assertion `t->rp->type == Gcalc_function::shape_line' failed in Gcalc_operation_reducer::end_line in maria-5.3-gi #841625 Assertion `m_poly_borders->next' failed in Gcalc_operation_reducer::count_slice in maria-5.3-gis #841638 Assertion `!m_prev \|\| m_prev->x != x \|\| m_prev->y != y' failed in Gcalc_shape_transporter::int_add_point in maria-5.3-gis #841662 Third assertion `n > 0 && n < SINUSES_CALCULATED*2+1' in get_n_sincos #841745 Assertion `!sp0->is_bottom()' failed in Gcalc_scan_iterator::find_intersections in maria-5.3-gis They mostly was caused by inprecision of double arithmetic. Fixed by changes in how to handle multiple intersections to keep their order right. Also ST_DISTANCE(GEOM, EMPTY_GEOM) was defined as NULL. per-file comments: mysql-test/r/gis-precise.result GIS bugfixes. test result updated. mysql-test/t/gis-precise.test GIS bugfixes. test cases added. sql/gcalc_slicescan.cc GIS bugfixes.
