5c6944d33f s3: Remove a pointless #endif/#ifdef pair 2009-10-22 16:33:44 +02:00

d942d248d6 Fix bug #6195 - Migrating from 3.0.x to 3.3.x can fail to update passdb.tdb correctly. For the clustering case. 
Clustered setups should have only ever used
the unsigned version of TDB_DATA in the
first place so they can't be in this mess :-).
Just do the normal upgrade in the clustered case.
Jeremy.

535311d187 s3:dbwrap: add dbwrap_delete(), dbwrap_store() and dbwrap_fetch() 
The _bystring function are now just tiny wrappers.

138b58bcec dbwrap: use db_open_tdb2() in for db_open_trans() if "dbwrap:use_tdb2=yes" 
For clustered setups you need to disable the ctdb backend for each
tdb which should use the tdb2 backend (e.g. ctdb:registry.tdb=no).

To disable tdb2 per tdb use something like "tdb2:passdb.tdb=no"

474916b70c dbwrap: add db_open_trans() 
This should be used when transactions are wanted.
For now it's just a wrapper of db_open(), but this
will change.

de565785f5 r23410: Merge the core of the cluster code. 
I'm 100% certain I've forgotten to merge something, but the main code
should be in. It's mainly in dbwrap_ctdb.c, ctdbd_conn.c and
messages_ctdbd.c.

There should be no changes to the non-cluster case, it does survive make
test on my laptop.

It survives some very basic tests with ctdbd enables, I did not do the
full test suite for clusters yet.

Phew...

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.
