I'm testing Subversion for my company and so far so good. I got a
little nervous after reading this thread. Currently, we have 26
repositories and 8 being source codes for web sites. I feared losing
the repositories. I'm on SVN 1.2 and that's safe because I read that
fsfs is the default in svn 1.2.
I just want to reassure my engineers that we're using fsfs instead of
bdb. I looked into the db directory and there are files/folders look
and the file, fs-type, contains a string: "fsfs".
If I see this, am I using fsfs? It should be.
Unfortunately, I have 2 repositories using bdb. I have different
files and directory structure in db directory. I have no idea why
they are on bdb.
How can I convert them from bdb to fsfs? I have many revisions in
both repositories and don't want to loose any of the revisions data.
Why the subversion development team choose BDB? Why not PostgreSQL or
