[postgis-devel] GEOS changes breaking PostGIS testcases

[Sandro Santilli]

FYI: I've committed improvements for the GEOS snapping algorithm, so that
ST_Snap is less likely to return invalid (collapsed) geometries.

Unfortunately some of the topology tests in PostGIS are expecting
outputs due to collapses and thus will now fail until tweaked.

I'm planning to change the expectances to match the new GEOS results
but of course doing so would mean the tests will fail with latest
GEOS release instead. Better ideas ?
