Thinking about this further, I may have this a bit backward. It's the
repository that is "built" for a particular BerkeleyDB version, not
the Subversion parts. Presumably when you're using svnadmin and when
you're using mod_dav_svn you're talking to the same repository. So
then, the error message you get from svnadmin shows that BerkeleyDB
4.2 is what svnadmin is using, but this isn't the right version for
accessing the repository. Conversely, your mod_dav_svn has no problem
using the repository, so maybe your mod_dav_svn is using a different
version of BerkeleyDB -- maybe you have multiple versions installed on
your server simultaneously.
Or is it possible that your Apache has just never been restarted after
BerkeleyDB was updated to 4.2, and that if you were to now restart
Apache, you would no longer be able to access the repository from
there either? I suppose you would prefer not to test that theory at
the moment. :) But it might be useful to know your Apache's uptime.
You may want to follow this FAQ entry to determine which version of
BerkeleyDB your repository is "built" for at this moment:
If you find your repository is "built" for BerkeleyDB < 4.2, you can
apparently upgrade it to BerkeleyDB 4.2 specs by using "svnadmin
recover". If you wanted to upgrade to a later version of BerkeleyDB,
this FAQ would be relevant:
Also note that as of Subversion 1.2, the default repository format is
no longer BerkeleyDB but "FSFS". If you manage to find a way to dump
your repository and load it into a new one, you'll get an FSFS
repository (unless you explicitly ask for a BDB one). FSFS was
specifically designed for Subversion to avoid the intricacies of
managing BerkeleyDB -- such as these version mismatches -- so if you
use FSFS, you won't ever have to deal with this again (or even have
BerkeleyDB installed). As you can imagine, I recommend using FSFS.
