[mapserver-users] Mapserver 7 - CLUSTER layer getfeatureinfo / php mapscript queryByPoint broken?

[AndyC79]

Hi,

Upgraded to MS 7 from 6.4.1 recently - getfeatinfo requests that used to
work against clustered layers, now return 500s with Apache logs detailing:

End of script output before headers: mapserv

Which as far as I understand means the mapserv process crashed?

request e.g:

http://<server>/cgi-bin/mapserv?map=/path/to/mapfile.map&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetFeatureInfo&FORMAT=png8&TRANSPARENT=true&QUERY_LAYERS=TEST&LAYERS=TEST&TILED=true&INFO_FORMAT=application%2Fjson&X=50&Y=50&SRS=EPSG%3A3031&STYLES=&WIDTH=101&HEIGHT=101&BBOX=-925990.5180299012%2C195459.73995354102%2C-432454.67464720976%2C688995.5833362325

I tried also using PHP mapscript to assemble a point query against the
cluster layer, however that also does not seem to work in MS 7. It fails at
the layerObj->queryByPoint method.

Makes me think there's either something fundamentally problematic with
querying CLUSTER layers in MS 7. Or perhaps the way I've had my mapfile
configured is now causing an issue.

** Can anyone confirm that getfeatureinfo / php mapscript queryByPoint is
working against CLUSTER layers in MS 7 ? **

The CLUSTERs draw fine. Just the querying that seems an issue.

Below extract from mapfile. I can provide further details if necessary.

	END
