Jon, Okay, thanks for looking into it!
To run the tests as-is you should download nik2img. From inside the unzipped test directory do: wget http://mapnik-utils.googlecode.com/svn/trunk/desktop/nik2img/nik2img.py export PATH=`pwd`:$PATH chmod +x nik2img.py ... then ./run_tests.sh Dane On Oct 23, 2008, at 4:18 PM, Jon Burgess wrote: > On Thu, 2008-10-23 at 15:42 -0700, Dane Springmeyer wrote: >> Mapnik Users, >> >> I've run into a repeatable failure (on both mac 10.5 and Ubuntu 8.04) >> of the mapnik Filter expression and have a test case. >> >> >> You can download the test case as a zip archive from here: >> http://mapnik-utils.googlecode.com/svn/trunk/sandbox/mapnik_filter_failure_test_case.zip >> >> Inside the zip archive are two shapefiles, two XML mapfiles, and a >> test script. >> >> The run_test.sh script utilizes nik2img to generate a simple graphic >> using each mapfile. >> >> The only difference between the mapfiles is that one points to a >> 'states.shp' shapefile which mapnik renders fully green highlighting >> the failure of the <Filter> expression, while the other points to >> 'states_working.shp' which for me renders with states in shades of >> green, blue or red, highlighting a working Filter on the [PEOPLE] >> attribute. > > The test script isn't working for me, but doing a simple binary > comparison between the files shows that only the dbf file are > different. > We can discount the prj file since that is not read by Mapnik. > > If I dump the the two dbf files with dbfdump (from shapelib utilities) > then the results are the same for the two files.
