CONNECTIONTYPE OGR is not working after upgrade to mapserver 7.2.2 from 6.4.1

Lars Fricke
Hello,

First of all: thank you for your time!

I have been running into a strange problem lately. We have a server running mapserver 6.4.1 (Debian GNU/Linux 8.0 jessie) that is accessing a remote WFS as client without any problems.
We have another (local development) server that has been upgraded to mapserver 7.2.2 (Ubuntu 18.04 bionic) and that can no longer access the WFS. Everything was fine with the older versions on that server, too (not certain if the mapserver upgrade happened at the same time as the Ubuntu upgrade).

The error received is:
msOGRFileOpen(): OGR error. GetLayer(LAYER_NAME) failed for OGR connection. Check logs.

The logs are not giving me any further information. Even I put debug level to 5 already. Also apache log is not giving me any clue, there is no error. Other layers on the same server open fine, as long a they do not need OGR. So I assume it is not a connection issue.

ogrinfo however can access the external WFS fine from the terminal.

Configuration:
Mapserver 7.2.2
gdal-bin 2.4.0+dfsg-1~bionic0 (from UbuntuGIS - unstable repo)

Ubuntu 18.04 bionic

I also have NextGIS repository activated but it does not seem that gdal/ogr is installed from there.

mapserv -v shows:
MapServer version 7.2.2 OUTPUT=PNG OUTPUT=JPEG OUTPUT=KML SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=CAIRO SUPPORTS=SVG_SYMBOLS SUPPORTS=RSVG SUPPORTS=ICONV SUPPORTS=FRIBIDI SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER SUPPORTS=SOS_SERVER SUPPORTS=FASTCGI SUPPORTS=THREADS SUPPORTS=GEOS SUPPORTS=PBF INPUT=JPEG INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE

I have also checkt $Path:
/home/lars/bin /usr/local/sbin /usr/local/bin /usr/sbin /usr/bin /sbin /bin /usr/games /usr/local/games /snap/bin

I am not certain, if that is correct but ogr seems to be in /usr/bin so I'd expect it's available for mapserver, too.
gdalinfo --formats does not show WFS, if that is the problem, where do I get gdal with WFS enabled?

The mapfile is the same on both servers (relevant code only):
 LAYER
    NAME "TEST"
    TYPE Point
    UNITS METERS
    CONNECTION "http://XXX&VERSION=1.1.0&SERVICE=WFS"
    CONNECTIONTYPE OGR
    STATUS ON
    DEBUG ON
    DEBUG 5
    DATA "

    METADATA
      "wfs_version"    "1.1.0"
      "wfs_title"    "TEST"
      "wfs_connectiontimeout" "300"
      "wfs_typename"    "Test_int"
      "wfs_maxfeatures"       "500"
      "gml_include_items" "all"
      #"wfs_srs" "epsg:25832"
      "gml_featureid"     "ID"
      "wfs_enable_request" "*"
    END # METADATA
    PROJECTION
      "init=epsg:25832"
    END # PROJECTION
     CLASS
      NAME "Testlayer"
      STYLE
        COLOR 190 87 66
        OUTLINECOLOR 255 0 0
        SIZE 4
        SYMBOL "circle_filled"
      END # STYLE
    END # CLASS
  END # LAYER

I'd really appreciate any help where to look further. I have been at this for a few days already. I tried to give as much information as possible, if something important is missing, please let me know.

Thanks again for your time!

To access a remote WFS service, be sure to set CONNECTIONTYPE WFS in
your layer, as in the example at
https://mapserver.org/ogc/wfs_client.html#example-wfs-layer

I guess I am not understanding your question properly.

@ Lars Schylberg

Thank you for your valuable hint and the very fast reply, I just got out of another task and tried immediately.

Apache2 error.log now gives me:
HTTP: Fetch(http://...?VERSION=1.1.0&SERVICE=WFS)
HTTP: libcurl/7.58.0 GnuTLS/3.5.18 zlib/1.2.11 libidn2/2.0.4 libpsl/0.19.1 (+libidn2/2.0.4) nghttp2/1.30.0 librtmp/2.3
HTTP: These HTTP headers were set: Accept: text/plain, application/json
GeoJSONSeq: First pass: 100.00 %
GDAL: GDALOpen(http://...?VERSION=1.1.0&SERVICE=WFS, this=0x565136f44fe0) succeeds as GeoJSONSeq.
GDAL: GDALClose(http://...?VERSION=1.1.0&SERVICE=WFS, this=0x565136f44fe0)

That does not really look like an error. The error displayed in the browser however remains the same.

@ Jeff McKenna
Thank you for taking thought upon this. Unfortunately the remote server only supports WFS 1.1.0 and up while to my knowledge mapserver only has native client support for WFS 1.0.0 . A colleague from a partner company has tried with 1.1.0 and the spacial filtering did not work. If there is a native way to use WFS 1.1.0 as client, I will be happy to check it out.

What is the result if you change "CONNECTIONTYPE OGR" to "CONNECTIONTYPE
WFS", and then execute at the commandline:

   shp2img -m mymap.map -o ttt.png -map_debug 3

Re: CONNECTIONTYPE OGR is not working after upgrade to mapserver 7.2.2 from 6.4.1

Lars Fricke
Thanks for the new test procedure.

With CONNECTIONTYPE WFS, the result of shp2img -m wfs.map -o ttt.png -map_debug 3 is:

Re: CONNECTIONTYPE OGR is not working after upgrade to mapserver 7.2.2 from 6.4.1

Thanks for providing the response, which indeed states "only WFS 1.0.0
or 0.0.14".

I just followed the GDAL WFS driver page now, and locally was able to
generate a map image with a VERSION=1.1.0 request, with the following steps:



- (the following steps are adapted from the GDAL WFS driver page
https://gdal.org/drv_wfs.html )

- create a new file named "wfs-request.xml"

- paste the contents of:

   <OGRWFSDataSource>
 
<URL>http://demo.mapserver.org/cgi-bin/wfs?SERVICE=WFS&amp;VERSION=1.1.0&amp;MAXFEATURES=1000</URL>
   </OGRWFSDataSource>

- (notice the escaped "&" as noted on the GDAL WFS driver page)

- make a copy of that file (copy/paste "wfs-request.xml" ) in case it is
overwritten by this process

- test this file/connection through the commandline:

     ogrinfo wfs-request.xml

- you should see a response listing the available layers:

        INFO: Open of `wfs-request.xml'
          using driver `WFS' successful.
                        1: continents
                        2: cities
                       
- now we know the name to use in our MapServer layer "DATA" parameter,
so in this case we will use "continents"
                       
- edit your .map file and point your layer to that wfs-request.xml in
the CONNECTION, and set the correct DATA parameter from the ogrinfo
response above, such as:

        LAYER
          NAME "continents-test"
          TYPE POLYGON
          STATUS ON
          CONNECTION "wfs-request.xml"
          CONNECTIONTYPE OGR
          DATA "continents"
          PROJECTION
            "init=epsg:4326"
          END
          CLASS
            NAME "My Continents"
            STYLE
              COLOR 255 128 128
              OUTLINECOLOR 96 96 96
            END
          END
        END # Layer

- (use my small mapfile for testing: https://pastebin.com/GYrXyc9A )

- now finally have MapServer generate a map image from that WFS version
1.1.0 connection, by testing at the commandline:

        shp2img -m wfs-110-client.map -o ttt.png -all_debug 5
       
- a file named 'ttt.png' should be generated of the map image, and at
the commandline the response should end with something like:

        msSaveImage(ttt.png) total time: 0.015s
        msFreeMap(): freeing map at 00228B70.
        freeLayer(): freeing layer at 001F1828.
        shp2img total time: 3.013s
       
*** tested with MS4W 4.0.0 (MapServer 7.4.0-dev, GDAL 2.4.0)

Hope that helps,

-jeff

Re: CONNECTIONTYPE OGR is not working after upgrade to mapserver 7.2.2 from 6.4.1

Lars Fricke
Hi Jeff,

You really did it! I was searching for missing libs, version mismatches and wrong path variables but it was as simple as using the xml file the way you pointed out.
I can confirm that everything works as expected now. I'd like to point out though (for the record) that the step of

ogrinfo wfs-request.xm

does not only test the file but also prepares it to be used. I tested using the file without first using ogrinfo but that did not succeed.

I still do not understand why this was not needed in Mapserver 6 but anyway the problem is solved.

Thanks so much for putting in all that effort and time to help so very quickly.  I think this list is one of the greatest strength of Mapserver and I want to thank everybody who is helping here!

Best

- edit your .map file and point your layer to that wfs-request.xml in the CONNECTION, and set the correct DATA parameter from the ogrinfo response above, such as:

    LAYER
      NAME "continents-test"
      TYPE POLYGON
      STATUS ON
      CONNECTION "wfs-request.xml"
      CONNECTIONTYPE OGR
      DATA "continents"
      PROJECTION
        "init=epsg:4326"
      END
      CLASS
        NAME "My Continents"
        STYLE
          COLOR 255 128 128
          OUTLINECOLOR 96 96 96
        END
      END
    END # Layer

- (use my small mapfile for testing: https://pastebin.com/GYrXyc9A )

- now finally have MapServer generate a map image from that WFS version 1.1.0 connection, by testing at the commandline:

    shp2img -m wfs-110-client.map -o ttt.png -all_debug 5
    
- a file named 'ttt.png' should be generated of the map image, and at the commandline the response should end with something like:

    msSaveImage(ttt.png) total time: 0.015s
    msFreeMap(): freeing map at 00228B70.
    freeLayer(): freeing layer at 001F1828.
    shp2img total time: 3.013s
    
*** tested with MS4W 4.0.0 (MapServer 7.4.0-dev, GDAL 2.4.0)

Hope that helps,
