More information would be useful here; are you using the Desktop or
Server edition?  Is the site on the internet, in which case we can take
a look at the problem?  Are you using Apache or IIS, and what sort of
configuration are you using (ScriptAlias or RewriteRule, moin.cgi or
farmconfig)?

It sounds like a web server misconfiguration; if by "page not found" you
mean a 404 error from the web server, then it's obviously not passing on
requests to moin.cgi or else it is asking for the wrong page.  It is
difficult to diagnose without further info.

Maybe first fix the IIS issue (see my last post) and look if you still 
get those error log entries.

Subject: [Moin-user] Could not load Config in wiki farm
Message-ID: <1e2af89e0606290800u16286c63na3e42f4d6265d89d@mail.gmail.com>

Hi,

I have a wikifarm setup, here:

http://imaging.mrc-cbu.cam.ac.uk/lug
http://imaging.mrc-cbu.cam.ac.uk/mri
http://imaging.mrc-cbu.cam.ac.uk/imaging

I have just tried to add a new wiki to this farm

http://imaging.mrc-cbu.cam.ac.uk/stats

However, I get a "Could not find required "Config" class in "stats.py"
- reproducible by going to the link above.

All the other wikis are working fine.  I have attached my
farmconfig.py file, and stats.py file, which is identical (barring
string edits) to (e.g.) the mri.py file for the 'mri' wiki.

I have checked that stats.py file imports with the path set correctly
as the apache user, the error page reports I am finding the correct
python version and have the path set correctly, and I don't have more
ideas how to debug this problem.  Any thoughts?

Best,

Matthew

I thought you should compare the difference between stats.py and lug.py.

I guess stats.py should be something like:

{{{
from MoinMoin.multiconfig import DefaultConfig
class Config(DefaultConfig):
...
}}}

Hi,

Thanks for the suggestion.

They are identical apart from the string definitions.  I have also
tried an identical copy of a working config, such as mri.py (which
would obviously point to the mri wiki), but get the same error.

The stats.py file, as all the other wiki configs in the farm, begin:

from farmconfig import FarmConfig
class Config(FarmConfig):

Best,

Matthew

I share your bafflement.  Here's all the troubleshooting I can think of.

What happens if you delete stats.py completely?  Do you get the same
error or does it complain about a missing file?

What happens if you remove one of the other wikis from the wikis
variable in farmconfig.py?

Is there perhaps a problem with the regexp "stats" (perhaps an existing
directory) - do you still get the problem if you substitute stats ->
foobar?

I couldn't see an obvious error in your config.

The error message you got is caused by a Python "AttributeError" - this 
is usually caused by some attribute being accessed, but not been defined 
before.

If you can't find the error with this information, you can hack 
MoinMoin/multiconfig.py to get more information:

Go to function _makeConfig(name).

See "except AttributeError" (and the error msg you got is below that).

Replace that code by something like (indent correctly as it was!):

    except AttributeError, err:
        msg = '''%(err)s
... (keep old text)
''' % {'name': name, 'err': err, }
        raise error.ConfigurationError(msg)

That should give you more information in the error msg you get.

Either it is a subtle bug in your configuration or in our error handling 
(maybe just something else triggers an AttributeError there).

Matthew, this is a bug in the moin code.

You can just avoid it by not using any name that exist under MoinMoin/ 
code directory. You see above, that it confuses the moin internal stats 
module with your configuration module.

So just use something else like "statswiki.py" or "ourstats.py" for your 
stuff and it will work.

If you have time, please file a bug report about that, so we don't 
forget fixing it in 1.6.

Excellent - thanks very much for tracking this down.

I will do that now.

Many thanks,
