#17886 closed defect (fixed)

Multipolygon test possibly wrong

Reported by: naoliv Owned by: Don-vip
Priority: normal Milestone: 19.08
Component: Core validator Version:
Keywords: multipolygon area Cc: stoecker


With the attached example file, where we have the same farm consisting of 2 different plots of land (grouped in the multipolygon), when we validate it we see an error about Multipolygon relation should be tagged with area tags and not the outer ways

One area is a landuse=farmland which is also part of that farm.
For me it seems that, for this case, the error message isn't right.

This warning comes from old style multipolygons check:

                    /* old style multipolygon - solve: copy tags from outer way to multipolygon */
                    errors.add(TestError.builder(this, Severity.ERROR, NO_STYLE_POLYGON)
                            .message(trn("Multipolygon relation should be tagged with area tags and not the outer way",
                                    "Multipolygon relation should be tagged with area tags and not the outer ways",

Is it still useful? We removed all of them last year no?

I also believe that old style multipolygons should be gone, so we can probably also drop related tests. They probably also aren't rendered anymore (at least newest osm2pgsql ignores them completely).

In 15244/josm:

fix #17886 - remove check for old-style multipolygons (removed from OSM database in May 2017)

That was a fancy project and it was successful. Yeah! I already forgot about it.
