Thomas: thanks for the info. The segfault you indicate below is solved with https://github.com/mapserver/mapserver/commit/937dcb6857501835b5489fa4bea321105412a20b. So my testing below is based on 6.2.1 + https://github.com/mapserver/mapserver/commit/937dcb6857501835b5489fa4bea321105412a20b.patch, thus introducing a new issue.

All works well, except for WMS GetCapabilities responses. The result is a truncated WMS Capabilities XML which gets truncated when MapServer is printing out the root Layer element. I've posted a minimal mapfile and the Python mapscript at https://gist.github.com/tomkralidis/f70afd49270cb8efb62f. Observations: - commenting out LAYER.METADATA.wms_layer_group eliminates the issue, but we require this functionality - commenting out LAYER.CLASSGROUP and LAYER.CLASS.GROUP, and uncommenting LAYER.METADATA.wms_layer_group eliminates the issue, but we require this functionality - the same mapfile works just fine with mapserv binary Any suggestions? I'm wondering whether the Python SWIG implementation affects this. ..Tom _______________________________________________ mapserver-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapserver-users _______________________________________________ mapserver-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapserver-users
