patch at<br>
<a href="https://github.com/mapserver/mapserver/commit/937dcb6857501835b5489fa4be" target="_blank">https://github.com/mapserver/mapserver/commit/937dcb6857501835b5489fa4be</a><br>
a321105412a20b.patch, we have a requirement to implement a WxS MapScript<br>
approach for our OWS (we have up until now using the mapserv binary).<br>
<br>
All works well, except for WMS GetCapabilities responses. The result is<br>
a truncated WMS Capabilities XML which gets truncated when MapServer is<br>
printing out the root Layer element.<br>
<br>
I've posted a minimal mapfile and the Python mapscript at<br>
<a href="https://gist.github.com/tomkralidis/f70afd49270cb8efb62f" target="_blank">https://gist.github.com/tomkralidis/f70afd49270cb8efb62f</a>. Observations:<br>
<br>
- commenting out LAYER.METADATA.wms_layer_group eliminates the issue,<br>
but we require this functionality<br>
- commenting out LAYER.CLASSGROUP and LAYER.CLASS.GROUP, and<br>
uncommenting LAYER.METADATA.wms_layer_group eliminates the issue, but we<br>
require this functionality<br>
- the same mapfile works just fine with mapserv binary<br>
<br>
Any suggestions? I'm wondering whether the Python SWIG implementation<br>
affects this.<br>
