[postgis-devel] failure in clipbybox2d test

Tue May 29 08:45:58 PDT 2018

I can not confirm the observed results locally or on CI. I have not updated
GEOS to latest commits though.

# SELECT '6', ST_AsText(ST_ClipByBox2d('POLYGON((0 0,5 4,5 6,0 10,10 10,5
6,5 4,10 0,0 0))', ST_MakeEnvelope(2,2,10,5)));
6 MULTIPOLYGON(((2.5 2,5 4,5 5,10 5,10 2,2.5 2)))
# select postgis_full_version();
POSTGIS="2.5.0dev r16548" [EXTENSION] PGSQL="100"
GEOS="3.7.0dev-CAPI-1.11.0 0" SFCGAL="1.3.1" PROJ="Rel. 4.9.3, 15 August
2016" GDAL="GDAL 2.3.0, released 2018/05/04 GDAL_DATA not found"
LIBXML="2.9.4" LIBJSON="0.12.1" LIBPROTOBUF="1.3.0" RASTER

Judging visually, your result is the needed one.

If that is improved in latest GEOS, we'd better get it released for PostGIS
2.5 :)
