2012-04-20s3-dbwrap: Add dbwrap_set_stored_callbackVolker Lendecke1-2/+36
This is a per-db function that is called whenever some record is modified
2012-04-20s3-dbwrap: Add "db_context" to "db_record"Volker Lendecke1-0/+6
2012-04-20s3-dbwrap: Add dbwrap_db_idVolker Lendecke1-0/+5
This returns a blob uniquely identifying the database
2012-04-19s3-dbwrap: Remove dead code: talloc_stackframe() cannot failAndrew Bartlett1-10/+1
2012-04-18s3-dbwrap: Add talloc_stackframe() callsAndrew Bartlett1-5/+21
This is in preperation for calling dbwrap from common code, where we may not have a stackframe set up. Andrew Bartlett
2012-04-17s3: Add dbwrap_try_fetch_lockedVolker Lendecke1-4/+23
This is designed to spread the load on individual ctdb records to allow upper layers to do backoff mechanisms. In the ctdb case, do not get the record if a local lock is already taken. If we are not dmaster, do at most one migrate attempt. For the tdb case, this is a nonblocking fetch_locked. If someone else has the lock, give up.
2012-02-27dbwrap: changed log level for information about lock orderAndrew Tridgell1-1/+1
we were filling our logs with lock ordering debug lines Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org> Autobuild-User: Andrew Bartlett <abartlet@samba.org> Autobuild-Date: Mon Feb 27 12:50:29 CET 2012 on sn-devel-104
2012-01-18s3: Enforce a lock order in dbwrapVolker Lendecke1-1/+80
This makes sure we do not deadlock from doing two dbwrap_fetch_locked in two processes in different orders. At open time, we assign a strict order to all databases. lock_order 1 will be locked first, lock_order 2 second. No two records of the same lock order may be locked at the same time.

2011-12-15s3-dbwrap: Make dbwrap_parse_record return NTSTATUSVolker Lendecke1-18/+16
Also, the parser now returns void. The parser is called if and only if dbwrap_parse_record returns NT_STATUS_OK. Signed-off-by: Michael Adam <obnox@samba.org>

2011-11-29s3:dbwrap: turn the fetch dbwrap method to NTSTATUS return code.Michael Adam1-12/+10
