VFK : errors reported by test_ogrsf utility

[Even Rouault]

To check it : go in apps, and 'make test_ogrsf' then run test_ogrsf on your test .vfk file. This utility can be used to check the conformance of drivers to a few expected behaviours. Attached the report I got.

I've noticed a few errors, among them :

1) the ones about 'Feature SRS differs from layer SRS' are IMHO relatively minor. It means you need to do poGeom->assignSpatialReference(poSRS) as far as I remember

2) the one about 'GetFeatureCount() may not be taking spatial filter into account' suggests that in your implementation of ::GetFeatureCount(), you should propably default to call OGRLayer::GetFeatureCount() when a spatial filter has been set. This will default to the dummy, but safe, implementation that iterates on all the features with GetNextFeature() and count them

3) there's one : 'ERROR: Claimed feature count 13 doesn't match actual, 26.' . I'm not sure why. The test does a ResetReading() and then iterate on GetNextFeature() and compares the number of iterations to GetFeatureCount(). Perhaps an issue with GetFeatureCount() on that particular layer ?

Note: test_ogrsf was segfaulting because an old bug I've fixed in latest revision in r18471

1) and 2) fixed in r18475.

3)

Linear features in SBP layer are formed by more records (each record determines one vertex). In this case all lines are formed by two vertices. Number features/records 13/26.

Seems to be fixed. Closing the ticket.
