No Layers when configuring TinyOWS with a Mapserver (.map) File

[balajeerc]

Am trying to expose a vector layer (loaded from shape file into PostGIS) as a WFS layer using tinyows.

Following the instructions in the mapserver/tinyows documentation, here is the .map file I have come up with so far:

MAP
    NAME "world"
    CONFIG "MS_ERRORFILE" "/home/balajeerc/Projects/Build_Dir/myproject/data/logs/mapservice_errors.log"
    EXTENT -180.000 -90.000 180.000 90.000

            "tinyows_onlineresource" "http://192.168.43.164:19090/vectors/world/wfs?"
            "wfs_title" "MyGIS Feature Service: World"
            "wfs_contact" "[email protected]"
            "wms_title" "MyGIS Feature Service: World"
            "wms_srs" "epsg:4326"
            "wms_enable_request" "*"
            "log_level" "15"
            "log" "/home/balajeerc/Projects/Build_Dir/myproject/deps/mygis-services-0.1/data/logs/wfs_world.log"
            "ows_contactorganization" "GeorbisServer"
            "ows_contactelectronicmailaddress" "[email protected]"
            "ows_contactperson" "Balajee.R.C"
        END
    END

    PROJECTION
        "init=epsg:4326"
    END

    LAYER
        NAME 'world_boundaries'
        CONNECTIONTYPE postgis
        CONNECTION "host=localhost user=mygis password=asdf123 dbname=mygis port=19095"
        DATA "geom from world_boundaries"
        TYPE POLYGON

            'wfs_srs' 'epsg:4326'
            'wms_srs' 'epsg:4326'
            'wms_title' 'world_boundaries'
            'tinyows_table'  'world_boundaries'
            'tinyows_writable' '1'
            'tinyows_retrievable' '1'
        END
        CLASS
            STYLE
                COLOR 128 128 128
                ANTIALIAS true
            END
        END
        PROJECTION
          "init=epsg:4326"
        END
        DUMP TRUE
    END
END

This .map file works fine with mapserver, i.e. I am able to render the feature layer as a WMS service using QGIS as a client.

However, the WFS service (served by tinyows) using the same file (set using TINYOWS_MAPFILE environment variable seems to show no layers in GetCapabilities (and hence QGIS is not able to load any).

The output from tinyows --check is as follows:

balajeerc@Balajee:~/Projects/tinyows-1.1.1$ ./tinyows --check
TinyOWS version:   1.1.0

Estimated extent:  No
Check schema:      Yes
Check valid geoms: Yes
Available layers:
balajeerc@Balajee:~/Projects/tinyows-1.1.1$ 

Note that even though I am using a 1.1.1 (release) version of tinyows, it prints tinyows version as 1.1.0. Also note that it prints no layers.

Wondering what is going wrong, I decided to step into the code. I recompiled code after turning off (-O2) optimizations and with debugging (-g) enabled.

I am only able to get so far as the ows_parse_config method in src/ows/ows_config.c. I am, for some reason not able to step into ows_parse_config_map in src/mapfile/mapfile.c. This probably has something to do with the fact that mapfile.c is generated by flex using src/map/mapfile.l.

After asking in the mailing lists (mapserver-users) and not getting any response, I suspect that this is a bug. Can someone please confirm this?
