Feature request #12150
check/fix vector layers before geoprocessing operations
|Pull Request or Patch supplied:||No||Resolution:||wontfix|
|Easy fix?:||No||Copied to github as #:||20343|
qgis (the underlying libraries) is less forgiving then other programs when it comes to do geospatial operations (clips, intersections, etc.) when the input(s) have geometry issues. It would be nice to have an option to have them checked before running any of those operations, throwing a warning and/or cleaning them on the fly (options are not missing, lwgeom, pprepair).
Currently QGIS silently creates an empty layer if there are topology issues with the clipping layer. See #12144.
QGIS should at least issue an error with the description of the problem or fix the problem if possible.

- Target version set to Future Release - Nice to have
- Category set to Vectors
- Subject changed from Clipping , intersection and perhaps other operations should check the integrity of the vector layer to check/fix vector layers before geoprocessing operations
