ST_AddIsoNode - containing_face value should be zero instead is NULL

[aperi2007]

Hi,

starting from an empty topology. Adding an Isolated Node with the ST_AddIsoNode , the "cointaining_face" field of Node table should be set to idface '0' (the UniverseFace) instead of NULL as now.

This code is a test:

select topology.DropTopology('topo_test2');
select topology.CreateTopology('topo_test2',3003);
select topology.ST_AddIsoNode('topo_test2',NULL,ST_GeomFromEWKT('SRID=3003;POINT(1 4)'));

select containing_face from topo_test2.node;

The actual result is (null)

it should be 0

Patch for ST_AddIsoNode, ST_AddIsoEdge, ST_GetFaceGeometry

[aperi2007]

Added patch for ST_AddIsoNode, ST_AddIsoEdge, ST_GetFaceGeometry to resolve tickets #971, #972 , #973, #976 http://trac.osgeo.org/postgis/attachment/ticket/971/patch_topology.zip

[strk]

Please use #965 for modifications to ST_AddIsoNode. It isn't yet clear what the behavior should be and we're waiting for feedback from the ISO people on that.

Feel free to file other tickets for ST_AddIsoEdge and ST_GetFaceGeometry, or add your patches to existing tickets.

Separate, smaller, focused patches are easier to deal with.

Thanks.
