Well, here we see that localizing error messages is a bad idea… could you translate it for us, please?

From the "Berkeley DB" part of it, I guess it's an incompatibility at that level (e.g. the bdb library currently used is older than the one used for creating the svn db; this might happen if you're using httpd and have a different set of apr libraries than svn).

In any case, regardless of the actual svn issue (see TracSubversion#Troubleshooting for help in this area), Trac shouldn't fail with an internal error in this situation.

SubversionException: ("Berkeley DB error for filesystem /var/lib/svn/repo/db while opening environment:\n", 160029)

This is subversion bug. I'm using DAV extension to access subversionapache and I can exclude Trac from suspicion. Navigating to ​http://localhost/svn produces: Error #160029: Could not open the requested SVN filesystem

I've used svnadmin recover /var/lib/svn/repo and everything looks fine, but wont work. svnadmin verify /var/lib/svn/repo confirms all the commited transactions.

I'm using db4.4. apr-utils and subversion are linked against it. Repository format is also compatible with 4.4.

Don't know howto trace this SVN issue, but it's for sure not Trac specific. Please close this ticket as I couldn't do it.

Thanks for the update.

I don't close the ticket yet, as I think we shouldn't let this SubversionException go through.

[Christian Boos]

trap this kind of SubversionException
