* Exit with ctdb_fatal if serverids_exist failsVolker Lendecke2014-05-241-4/+4
| | | | | | | | | | | The only reason why this could fail is a severe ctdb communications problem. The normal way to deal with this is ctdb_fatal. This avoids a confusing panic in get_share_mode_lock when ctdb is shutdown while this call happens.

* dbwrap_ctdb: only fetch a read-only copy if we had a record already.Rusty Russell2012-03-051-2/+3
| | | | | | | | | | | | | Because revoking read-only copies of records is expensive, we only want ctdbd to do it for high-turnover records. A basic heuristic is that if we don't find a local copy of the record, don't ask for a read-only copy. The fetch itself will cause ctdbd to migrate the record, so eventually we will have a local copy. Next time it gets migrated away, we'll call ctdbd_fetch() with local_copy = true.

* ctdbd_conn: fetch read-only copies of records.Rusty Russell2012-03-051-2/+2
