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

[Richard Greenwood]

I am also unable to get tinyows to work using a map file, even with the
example map file from the documentation. I have both the example and my own
layer working with an XML file, so I believe there is either a bug with map
file support or something missing from the documentation.

Regardless of whether I have a valid or invalid map file tinyows always
returns:
   
  Unknown layer name
   
I've tested with both an OpenLayers web interface and with QGIS. I built
1.1.1 from source on Ubuntu 14.04.

Can anyone suggests steps that I should take to narrow down the problem
more?

Thanks,
Rich

[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

WEB
METADATA
"tinyows_schema_dir"
"/home/balajeerc/Projects/Build_Dir/myproject/deps/mygis-services-0.1/data/schema"
"tinyows_onlineresource" "
http://192.168.43.164:19090/vectors/world/wfs?;
"wfs_title" "MyGIS Feature Service: World"
"wfs_contact" "supp...@giscompany.com"
"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" "MyCompany"
"ows_contactelectronicmailaddress" "cont...@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@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@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
)
