Volker Lendecke	a950301685	r23220: Add traverse_read to dbwrap ... (This used to be commit b38dc5ffdfe9fdc2879c57dc181815f06b4747fe)	2007-10-10 12:22:55 -05:00
Volker Lendecke	4c185a6077	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.
