2008-08-13handle two special casesAndrew Tridgell1-16/+42
1) when all nodes write the same value to the record, or when writing a value that is already there, we can skip the write and save ourselves a network transactions 2) when all remote nodes fail an update, and we then fail a replay, we don't need to trigger a recovery. This solves a corner case where we could get into a recovery loop (This used to be commit 2481bfce4307274806584b0d8e295cc7f638e184)
2008-08-13put a limit on the number of retries. I found a case where a recoveryAndrew Tridgell1-0/+12

2008-08-13dbwrap ctdb: add a retry loop to the persistent store operation.Michael Adam1-51/+120
This is because ctdbd can fail in performing the persistent_store due to race conditions, and this does not mean it can't succeed the next time. To not loop infinitely, this makes use of a new parametric option: "dbwrap ctdb:max store retries" (integer) which defaults to 5 and sets the upper limit for the number or repeats of the fetch/store cycle. Michael (This used to be commit 2bcc9e6ecef876030e552a607d92597f60203db2)
2008-08-13dbwrap ctdb: release the lock before calling ctdbd_persistent_store()Michael Adam1-0/+26
in the persistent db_ctdb_store operation. This is to prevent deadlocks in db_ctdb_persistent_store(). There is a tradeoff: Usually, the record is still locked after db->store operation. This lock is usually released via the talloc destructor with the TALLOC_FREE to the record. So we have two choices: - Either re-lock the record after the call to persistent_store or cancel_persistent update and this way not changing any assumptions callers may have about the state, but possibly introducing new race conditions. - Or don't lock the record again but just remove the talloc_destructor. This is less racy but assumes that the lock is always released via TALLOC_FREE of the record. I choose the first variant for now since it seems less racy. We can't guarantee that we succeed in getting the lock anyways. The only real danger here is that a caller performs multiple store operations after a fetch_locked() which is currently not the case.

2007-10-10r24773: Fix a ctdb connection lockupVolker Lendecke1-4/+11
The lockup could happen when packet_read_sync() gets two packets in a row, the first one being an async message, and the second one being the response to a ctdb request. Also add some debug msg to ctdb_conn.c, and cut off the "locking key" messages to only dump 20 hex chars at debug level 10. >10 will dump everything.

2007-10-10r23410: Merge the core of the cluster code.Volker Lendecke1-0/+451
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... Volker (This used to be commit 15553d6327a3aecdd2b0b94a3656d04bf4106323)
