[ZMapServer-Developers] Patches for WMSAdapter

[Titus v.d. M. <mal...@cl...>]

I have now a few addtitions to WMSAdapter.py, WMSClient.py, 
wmsCapabilities.zpt and wmsMetaData.zpt

   * a refresh button for the "wms capabillities" tab
     (get new capabillities from the WMS server)
   * an slightly improved capabillities parser
     (arbitraryly deep nested layers)
   * getFeatureInfo Support
   * wmsMetaData.zpt shows protocol version

I now want to know how to contribute these changes.  Sean, in one of 
your last mails you asked me if I have a sourceforge accoutn.  I don't 
have one and I don't really know how this sourceforge stuff works.  
Would I commit my changes directly into the main CVS-tree?  Somehow I 
would prefer if you would look over my changes before cecking it in.  
Maybe you don't like some of the things I do.  Therefore I propose to 
send you either one patch containing everything the simply the affected 
files.

Some things remain unsolved:

   * getFeatureInfo:  Mapserver returns error-messages as
     png files (not in the specified format)

As reponse format for getFeatureInfo requests Mapserver supports three 
formats: text/html, text/plain and GML.  There are now two problems:

   * If I send a getFeatureInfo request for a layer containing
     pixel-data, Mapserver returns a error message that is
     obviously wrong.  It tells that the QUERY_LAYERS parameter
     was not supplied (which is not true in my case)

   * the errormessage is a png-file with the message drawn on
     it (not GML or whatever I specified).

It is left to the user of WMSAdapter to detect this and do something 
appropriate.

Another nice thing (besides the solutions for these problems) would be 
the validation of the capabillities before the actual parsing.

Sorry, this is little bit much at once.
