Python failing to find correct Subversion libraries
 

Hello,

We had Subversion 1.4 installed on Fedora 6 working with WebSVN for several months. Then we upgraded to Subversion 1.5 and WebSVN started showing our repositories but not showing any data. Everything besides WebSVN concerning Subversion with 1.5 is working. So I tried to install a different repos viewing tool called ViewVC and I'm getting this error in the browser :

An Exception Has Occurred
Python Traceback

Traceback (most recent call last):
File "/usr/local/viewvc-1.0.7/lib/viewvc.py", line 3746, in main
request.run_viewvc()
File "/usr/local/viewvc-1.0.7/lib/viewvc.py", line 265, in run_viewvc
cfg.general.svn_path)
File "/usr/local/viewvc-1.0.7/lib/vclib/svn/__init__.py", line 606, in __init__
self.repos = repos.svn_repos_open(rootpath, self.pool)
File "/usr/lib64/python2.4/site-packages/libsvn/repos.py", line 55, in svn_repos_open
return apply(_repos.svn_repos_open, args)
SubversionException: ("Expected FS format '2'; found format '3'", 160043)

I think this is because Python is still bound to Subversion 1.4. We had to address this problem initially after installing 1.5 but I don't know how to fix this instance of it. I need to know how to make this incarnation of Python point to Subversion 1.5 instead of 1.4.

Thanks

Try this to see which svn library python is using:

(It's also possible that your _client.so file is in a different spot. Some distros mix those things around.)

Thanks for the response. Python was using the 1.4.3 libsvn bindings. I copied over the old bindings with new ones I built from SVN 1.5 source code. That caused viewVC to work except for one thing.

When I click "Annotate" I get this output.

Any ideas?
