Description
The ValidateTopology function does not currently check if edge linking is correct. It probably should.

For reference, #4709 is a bad consequence (backend crash) of a topology with edge-linking corruption, so dealing with it with ValidateTopology becomes more important.

Another problem with function is that uses a lot of time .
Does make a sense to make optimal parameter bbox to limit the area to check ?
comment:6 by , 4 years ago
There are a number of validity checks that could be performed within a limited bounding box yes, I'm thinking of:
- Edge linking (for all nodes falling in the bbox)
- Consistent side-labelling for linked edges

Remi: where can your rc_RecomputeEdgeLinking function be found ? It'd be interesting to look at it now

For the record: I filed #4942 to provide a RecomputeEdgeLinking function, to go with the new check
