[Mapbender-users] Heads-up for MapServer users: start removing all references to DUMP in your mapfiles now...

publish their services)

Hello everyone!

This is a big heads-up, that the upcoming MapServer 8.0 release (and the 
current MapServer source code if you compile from the GitHub 
[unreleased] source as of today) will cause an error to be thrown if 
your LAYER contains the DUMP parameter:

   loadLayer(): Unknown identifier.  Parsing error near (DUMP): line xxx

So it would be smart now to review all of your mapfiles to make sure 
that any references to DUMP in your layers are commented or removed. 
(DUMP was first deprecated back in the 6.0 release, and using LAYER 
METADATA is required instead)

For example, here is an example that uses METADATA to expose (or dump) 
all attribute fields for a layer that is served through WFS:

     NAME "continents"
       "wfs_title"         "World continents"
       "gml_include_items" "all"
       "gml_featureid"     "ID"
       "wfs_enable_request" "*"

*the next MS4W release will definitely contain this change, so please be 
sure to start removing DUMP from your mapfiles now...

Thanks all!


Thank-you for using MS4W.
