[MapProxy] Mapproxy FastCGI problem

[Christian Willmes]

Hi,

I have a problem with my MapProxy setup after an upgrade from 1.1.1 to
1.4.0. (I know, a long overdue update, but...)

I updated MapProxy using 'pip install --upgrade --no-deps MapProxy'.

The (updated) Server is working fine if I start it with 'paster serve
etc/config.ini':
<<<<
$ paster serve etc/config.ini
2012-11-08 14:53:12,634 - INFO -
14204:mapproxy.config:load_configuration_file - reading:
/var/local/mapproxy/etc/mapproxy.yaml
2012-11-08 14:53:12,890 - INFO - 14204:mapproxy.system:<module> - using
libproj for coordinate transformation
Starting server in PID 14204.
>>>>

But using the existing fcgi/apache config it is not working (see
MapproxyApacheError Log in Attachment). The same configuration (see
mapproxy.fcgi in attachment) was working before the upgrade.

>From the error logs, there seems to be an error regarding the
'application = loadapp(...'. Is there another recommendet way how to
load the app? In the documentation[1] this is not documented (as far as
I can see). It referes directly to the 'application', but does not state
how to load the applacation.

Thanks for any help and hints!

Best regards,
Christian

PS: The system is a CentOS 5 (I have to use it and I am not allowed to
upgrade it), so sorry for the old python 2.6 version, is this maybe the
cause of the problem?
