[mapserver-users] No Layers when configuring TinyOWS with a Mapserver (.map) File

[Balajee R.C]

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

                "wfs_title" "MyGIS Feature Service: World"
                "wfs_contact" "support at giscompany.com"
                "wms_title" "MyGIS Feature Service: World"
                "wms_srs" "epsg:4326"
                "wms_enable_request" "*"
                "log_level" "15"
                "log"

                "ows_contactelectronicmailaddress" "contact at giscompany.com"
                "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
            METADATA
                'wfs_title' 'world_boundaries'
                'wfs_namespace_prefix' 'tows'
                'wfs_namespace_uri' 'http://www.giscompany.com/'
                '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 at Balajee:~/Projects/tinyows-1.1.1$ ./tinyows --check
    TinyOWS version:   1.1.0
    FCGI support:      Yes
    Config File Path:
/home/balajeerc/Projects/Build_Dir/myproject/data/service_data/data/wfs/world.map
(Mapfile)
    PostGIS Version:   2.1.8
    PostGIS dsn:       host=localhost user=mygis password=asdf123
dbname=mygis port=19095
    Output Encoding:   UTF-8
    Database Encoding: UTF8
    Schema dir:
/home/balajeerc/Projects/Build_Dir/myproject/deps/mygis-services-0.1/data/schema
    Display bbox:      Yes
    Estimated extent:  No
    Check schema:      Yes
    Check valid geoms: Yes
    Available layers:
    balajeerc at Balajee:~/Projects/tinyows-1.1.1$

Note that even though I am using a 1.1.1 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`.

At this point I am completely stuck and at a brick wall as to what might be
going wrong. Can someone here please help?

TinyOWS version: 1.1.1 (Release
<https://github.com/mapserver/tinyows/releases/tag/v.1.1.1>)
