Log a warning when an unsupported geometry type is skipped
----------------------------------------------------------
Key: GEOT-2524
URL: http://jira.codehaus.org/browse/GEOT-2524
Project: GeoTools
Issue Type: Improvement
Components: data jdbc, data jdbc-ng, data oraclespatial, data postgis
Affects Versions: 2.5.5
Reporter: Ben Caradoc-Davies
Priority: Minor
Unsupported geometries are silently skipped. Known to affect gt-oracle-spatial.
Should probably check that all other data stores log a warning so that users
can diagnose this problem. One issue is that, if there are many skipped
geometries and users rely on this behaviour, large amounts of unwanted log
information may be written. Perhaps only log the first time an unsupported
geometry is seen? Watch the nasty state creep into the data store ...

Hi all-
I'm having an issue when using the oracle spatial plugin. There are 2
rows in my table that when selected from the WFS fail to return any
point/shape information. This happens on even a simple WFS getFeature
filtered by ID, like below. One OBJECTID value is working and
returning all 6 columns from my table, while the same request for
another OBJECTID is returning only 5 columns, always excluding the
SHAPE/spatial column.
<wfs:GetFeature service="WFS" version="1.1.0"
xmlns:myns="http://my.url"; 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://www.opengis.net/wfs
http://schemas.opengis.net/wfs/1.1.0/wfs.xsd";>
<wfs:Query typeName="myns:FEATURE_NAME">
<ogc:Filter>
<ogc:PropertyIsEqualTo>
<ogc:PropertyName>OBJECTID</ogc:PropertyName>
<ogc:Literal>716</ogc:Literal>
</ogc:PropertyIsEqualTo>
</ogc:Filter>
</wfs:Query>
</wfs:GetFeature>
I turned on verbose logging and tracked the logic down to the oracle
spatial plugin.
"28 May 16:39:43 DEBUG [data.oracle] - About to create Geometry
convertor for FEATURE_NAME.SHAPE"
I'd like to step through the source to try and understand what might
be different about the 2 "bad" rows versus the others, but I have no
clue where to obtain the source code. Any advice on source code
location or possible solutions to the problem at hand would be
appreciated.
Thanks!
Sarah

I figured it out. Those 2 rows are of type Compound Line String (as
indicated by the Elem Info returned from Oracle). According to
ETYPE.java and the SDO.java, this type (ETYPE.COMPOUND) is not
supported. Makes sense, but I wish there'd been some logging to
indicate it was skipping my geometry. If the same rules apply to NG,
it'd be great to include that logging.
Thanks for helping me find the source so I could figure this out.
