WCS 1.1: GetCapabilities error with Python MapScript

[schpidi]

Python MapScript crashes on a GetCapabilities request and version 1.1 or higher (...?service=WCS&request=GetCapabilities&version=1.1) with the error message: MapServerError: msLoadProjectionString(): Projection library error. Unrecognised OGC CRS def 'urn:ogc:def:crs:OGC::imageCRS'.

Other requests e.g. GetCoverage with Python MapScript and the GetCapabilities request with the cgi version and the same .map file are answered correctly.

taking a look...

This ticket requires more detail to reproduce. It needs a mapfile and a script that invokes a specific request demonstrating the problem. Supporting data files *may* not be required if the GetCapabilities failure occurs regardless of their presence.

The shortest mapfile still providing something with the cgi version and resulting in the described error with Python MapScript is: {{{MAP

WEB

METADATA

"ows_onlineresource" "​http://something?"

END

END LAYER

NAME "a" DUMP TRUE DATA "test.tif" TYPE RASTER METADATA

"ows_srs" "EPSG:4326"

END

END

END}}}

I'm not sure what the script you request should do exactly?

[schpidi]

Test tif file used in the mapfile.

I have tried with the following map, and test script (and your test.tif) and things seem to work ok with MapServer from subversion trunk.

MAP
  WEB
    METADATA
      "ows_onlineresource" "http://something?"
    END
  END 

  LAYER
    NAME "a" 
    DUMP TRUE 
    DATA "test.tif" 
    TYPE RASTER 
    METADATA
      "ows_srs" "EPSG:4326"
    END
  END
END

import mapscript

ows_req = mapscript.OWSRequest()
ows_req.setParameter('SERVICE','WCS')
ows_req.setParameter('REQUEST','GetCapabilities')
ows_req.setParameter('VERSION','1.1.1')

map = mapscript.mapObj( 'test.map' )
mapscript.msIO_installStdoutToBuffer()
dispatch_status = map.OWSDispatch( ows_req )
print mapscript.msIO_getStdoutBufferBytes()

Could you try the same at your end to see if it works?

[schpidi]

I tried with your scripts but with my currently installed version 5.4 of MapServer. Still getting the error.

I will try the trunk version when I have returned from Sydney on Tuesday. Many thanks for the moment!

Error seems to be resolved in trunk.
