[mapserver-users] mapserver 6.4.1 crash on raster query

2016-07-13 Thread Stephen Woodbridge 

Hi all,

I am getting a crash with memory corruption in mapserver 6.4.1 when 
doing a query. The strange this is that I have two identical mapfiles 
where the only difference is the tif files being referenced by it and 
while they both crash the errors are slightly different as can be seen 
in the gdb backtrace below.


Any thoughts on how to fix this?

Re: [mapserver-users] How to make uvraster background transparent?

Ooops, you are correct. The layer was setup as a jpeg in OL. I changed 
it to png and that fixed the issue.


Thanks,

[mapserver-users] Python MapScript via WSGI examples

2016-07-13 Thread Kralidis, Tom (EC) 
Hi all: we are looking into updating our Python MapScript (CGI-based) wrappers
to leverage WSGI, and are having integration issues as part of testing.

We are using 6.4.2 on Ubuntu 14.04.  See example in [1] (against
any mapfile is fine).  Simple run with python ./mapscript-wsgi.py which makes
the server available on localhost:8000 by default.

Issues:

- the value in 
https://gist.github.com/tomkralidis/9adbd4864c03647aa7eb4f96a3c33297#file-mapscript-wsgi-py-L18
 ends up being a Python None type for some reason when it should be a string of 
the content-type
- issuing a, say, WMS 1.3.0 GetCapabilities request yields the venerable 
MapServer "This script can " default message, when I am expecting 
Capabilities XML

Any ideas what I'm doing wrong here?

..Tom

[mapserver-users] How exclude some items in a text/plain response for a GetFeatureInfo request

2016-07-13 Thread Andrea Peri 
Hi,
Doing a GetFeatureInfo request,
I notice the
gml_exclude_items for exclude some items from response
is working only for GML response.
But if the request is for a text/plain response it return always all the items.
There is a command to exclude some items from a text response ?

Thx,

Steve,

The black color is coming from somewhere else, uvraster layers are
transparent, c.f. change/set the imagecolor in
