r22775: For the cluster code I've developed a wrapper around tdb to put different
database backends in place dynamically.
The main abstractions are db_context and db_record, it should be mainly
self-describing, see include/dbwrap.h. You open the db just as you would open
a tdb, this time with db_open(). If you want to fetch a record, just do the
db->fetch() call, if you want to do operations on it, you need to get it with
fetch_locked().
I added dbwrap_file.c (not heavily tested lately) as an example for what can
be done with that abstraction, uses a file per key. So if anybody is willing
to shape that up, we might have a chance on reiserfs again.... :-)
This abstraction works fine for brlock.tdb, locking.tdb, connections.tdb and
sessionid.tdb. It should work fine for the others as well, I just did not yet
get around to convert them.
If nobody loudly screams NO, then I will import the code that uses this soon.
