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

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 (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?
