catwalk problem in recent 0.9 versions (a2-a4, SVN 1160)

[Mike Sarahan]

Hello all,

I recently upgraded to 0.9a4, and was sad to see catwalk kick the
bucket on my installation. It won't load, and posts the following
output (at end of message). Getting SVN didn't fix it. I am
admittedly not very good at bug hunts.

This has been mentioned here:
http://groups.google.com/group/turbogears/browse_thread/thread/9d291a2bf5e178ce/6a865b4c980b532f?lnk=raot#6a865b4c980b532f

But it wasn't related to the other thread it was posted in, and I
didn't want it to get passed over.

Any ideas? Catwalk is an amazingly helpful tool, thanks for all the
great work on it, Ronald.

Hi Mike,
Nothing like flattery to get me out of the bush =)
Can you please add the following line before the offending line 607
on turbogears/toolbox/catwalk/__init__.py?:

print turbogears.util.get_package_name()

And tell me what the yielded path is? It seams that os.path.join
doesn't like what it gets.
Cheers
Ronald

Ronald,

I put the line in, but how should I get output from it? I tried to
access the site, but I just get the 500 message and the dump above. my
server log also just has the traceback.

running python __init__.py also didn't give me any output.

Thanks for the help!

I forgot to mention something that's very important. This is a
non-standard setup. It's running on a shared system, Dreamhost (they
run Debian Linux on their servers). I have my own little python
install inside my home folder, and Turbogears lives there, not
/lib/python or whatever.

I hope this helps.

Mike

It's definitely a problem with the shared system. Catwalk works just
fine on a similar install, minus the custom python install and FCGI
garbage necessary for functionality with Dreamhost.
