[mapserver-users] Parens making GetFeature crash with Mapserver 7

[thomas bonfort]

Hi Âlex,

I've tried your testcase (or at least the closest I could reproduce)
in the msautotest/wxs directory with

export REQUEST_METHOD=POST
export QUERY_STRING=map=wfs_filter.map
echo '<wfs:GetFeature xmlns:wfs="http://www.opengis.net/wfs"
service="WFS" version="1.1.0"
xsi:schemaLocation="http://www.opengis.net/wfs
http://schemas.opengis.net/wfs/1.1.0/wfs.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><wfs:Query
typeName="popplace" srsName="EPSG:4326"
xmlns:feature="http://mapserver.gis.umn.edu/mapserver"><ogc:Filter
xmlns:ogc="http://www.opengis.net/ogc"><ogc:PropertyIsEqualTo
matchCase="false"><ogc:PropertyName>NAME</ogc:PropertyName><ogc:Literal>foo
(bar)</ogc:Literal></ogc:PropertyIsEqualTo></ogc:Filter></wfs:Query></wfs:GetFeature>'
| mapserv

and I get back a reasonable result:

<?xml version='1.0' encoding="ISO-8859-1" ?>
<wfs:FeatureCollection
   xmlns:ms="http://mapserver.gis.umn.edu/mapserver"
   xmlns:gml="http://www.opengis.net/gml"
   xmlns:wfs="http://www.opengis.net/wfs"
   xmlns:ogc="http://www.opengis.net/ogc"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://mapserver.gis.umn.edu/mapserver
http://localhost/path/to/wfs_simple?SERVICE=WFS&VERSION=1.1.0&REQUEST=DescribeFeatureType&TYPENAME=popplace&OUTPUTFORMAT=text/xml;%20subtype=gml/3.1.1
 http://www.opengis.net/wfs
http://schemas.opengis.net/wfs/1.1.0/wfs.xsd">
   <gml:boundedBy>
      <gml:Null>missing</gml:Null>
   </gml:boundedBy>
</wfs:FeatureCollection>


can you check that your testcase is still failing as there have been
quite a few recent changes in that part of the code.

regards,
thomas
