[Pywps-devel] [OSGeo-UK] Catchment Finder: An example of OpenData + OS Software

[Jorge de Jesus]

Hi to all

This is a forward email from peter wells and faunalia UK, comments ?!I
think that the setup.py problem was already fixed in the last release,
but I'm not so certain about the LOCATION_NAME.



I think I've got to the bottom of the GRASS_LOCATION issue - it was an
intermittent problem but then started happening very regularly the other
day so I decided to delve a bit deeper.  I've tried to add all my notes
so far which will hopefully be useful for you guys. 

I've also copied in my colleague Paolo for his information...

*LOCATION_NAME 'bug'*

It seemed that the grass location was randomly being set to uk:uk
The only thing I've been able to track this down to is line 131 in the
stable version of Grass.py where the LOCATION_NAME environment variable
is set.  self.setEnv() is written in a way that appends values if they
already exist (fine for paths but I think this ma be where my problem
comes from).  I've now updated self.setEnv() to:

    def setEnv(self,key,value,append=True):
        """Set GRASS environmental variables """

        origValue = os.getenv(key)
        if origValue and append:
            value  += ":"+origValue
        os.putenv(key,value)
        os.environ[key] = value
        return

and changed lines 130 to 132 to look like:

self.setEnv('LOCATION_NAME',self.locationName, append=False)

Fingers crossed this will solve the issue permanently. 

*Broken setup.py*

When trying to run the 'clean' install method, setup.py failed to
process the templates.  In the end I had to hard-code baseDir on line
105 to:

baseDir =
os.path.join('/usr/local/lib/python2.6/dist-packages/pywps-3.2.1-py2.6.egg',
            name,"Templates")

After your other comment regarding Wsdl, I also added 'Wsdl' to the
template_files array on line 110 and now Wsdl seems to be working. 

Aside from those issues, everything else has gone really well.  I seem
to remember some bits of the documentation (installation/configuration)
were a bit confusing and may possibly need updating but can't remember
exactly which bits.  If it's important for you guys, it may be worth
getting someone to step through the installation/config instructions to
do a documentation test. 

I hope this is useful and thank you very much for both PyWPS and your
comments. 


Kind regards,

Pete
