[Pywps-dev] Raster Output error

[Jachym Cepicky]

Hi Lorenzo,

There are two bugs as I understand. The first one:

IOError: [Errno 2] No such file or directory:
'/tmp/pywps/pypws_process_lQqN_6/done'

do you have /tmp/pywps/ directory in you system (and is it writeable?)

The second bug is about attempt to write log to database

nice report btw, with the process I believe, we can fix it (both) once we
find out what the problem could be
