[WFS] Error when running GetFeature requests with Filter to GML data via OGR

[tomkralidis]

I have a GML document on disk (sample data attached in next comment).

The data runs through ogrinfo with no apparent problems.

When I run an OGC:WFS GetFeature request against this data, with no filter, the
expected response returns (note that gml:name element is malformed, but that is
covered in bug 1142):

http://devgeo.cciw.ca/cgi-bin/mapserv/ecows?version=1.0.0&service=WFS&request=GetFeature&typename=obs

When I attempt to apply a filter to this GetFeature request:

http://devgeo.cciw.ca/cgi-bin/mapserv/ecows?version=1.0.0&service=WFS&request=GetFeature&typename=obs&filter=<Filter><PropertyIsEqualTo><PropertyName>datetime</PropertyName><Literal>2004-10-30T00:00:00Z</Literal></PropertyIsEqualTo></Filter>

a 500 error is returned.  The following lines show in the logfile:

[Tue Dec 21 17:56:40 2004] [error] [client 192.75.68.5] free(): invalid pointer

test data for this bug

Also not working against SDE.  It is important for us to be able to serve data
from SDE via WFS.

We tried against a shapefile and SDE.  Shapefile works, SDE is not.  Here's a
summary....

DescribeFeatureType:  <!-- ERROR: Failed openinig layer ecozones --> is embedded
in XML output

GetFeature with filter (formatted for here)
<Filter>
  <PropertyIsEqualTo>
    <PropertyName>ECOZONE</PropertyName>
    <Literal>13</Literal>
  </PropertyIsEqualTo>
</Filter>

GetFeature with no filter works as expected.

I forgot part of my error for GetFeature with Filter....

the server returns with a "missing" error:

Did some poking with my problem of SDE and WFS+filtering.  It works with version
4.2.5, and not with 4.4 beta 2, so something must have happened between those
releases.

Tom, does the same happen for your connection?

[tomkralidis]

I'm not sure.  I only run and am working off latest CVS.

I have done the correction in the latest CVS and in 4.4.x branch. I tested the
fix against Tom's gml test data. 

Not sure if it fixes the SDE issue : Liz (or Tom) could you try using the latest
mapserver  cvs to do the same testing against SDE layers. I can provide windows
binaries if necessary.  

[tomkralidis]

Test case run again with latest CVS.  Works -- nice!!

Liz: can you test against SDE?

[godwinl@…]

It's now working for me.  Thanks!!!

[assefa]

Marking it as Fixed as Per Tom's and Liz's comments. Thanks for testing.
