* move the dbwrap library to the top levelMichael Adam2012-05-141-398/+0

* s3-dbwrap: Add dbwrap_set_stored_callbackVolker Lendecke2012-04-201-2/+36
| | | | This is a per-db function that is called whenever some record is modified
* s3-dbwrap: Add "db_context" to "db_record"Volker Lendecke2012-04-201-0/+6
|
* s3-dbwrap: Add dbwrap_db_idVolker Lendecke2012-04-201-0/+5
| | | | This returns a blob uniquely identifying the database
* s3-dbwrap: Remove dead code: talloc_stackframe() cannot failAndrew Bartlett2012-04-191-10/+1
|
* s3-dbwrap: Add talloc_stackframe() callsAndrew Bartlett2012-04-181-5/+21
| | | | | | | This is in preperation for calling dbwrap from common code, where we may not have a stackframe set up. Andrew Bartlett
* s3: Add dbwrap_try_fetch_lockedVolker Lendecke2012-04-171-4/+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.
* dbwrap: changed log level for information about lock orderAndrew Tridgell2012-02-271-1/+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
* s3: Enforce a lock order in dbwrapVolker Lendecke2012-01-181-1/+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.
* s3-dbwrap: All relevant backends provide parse_record(). Remove the fallback.Volker Lendecke2011-12-151-37/+0

* s3-dbwrap: Rewrite dbwrap_fallback_parse_record based on dbwrap_fetch_lockedVolker Lendecke2011-12-151-4/+13
| | | | | | This is in preparation to remove the db_context->fetch function pointer Signed-off-by: Michael Adam <obnox@samba.org>
* s3-dbwrap: Make dbwrap_parse_record return NTSTATUSVolker Lendecke2011-12-151-18/+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>

* s3: Remove unused dbwrap_record_get_private_dataVolker Lendecke2011-12-021-5/+0
| | | | | db_record->private_data is for backends which can include dbwrap_private.h anyway.
* s3:dbwrap: turn the fetch dbwrap method to NTSTATUS return code.Michael Adam2011-11-291-12/+10
| | | | | This implement more correct NTSTATUS handling inside the backends. This ensures that data.dptr != NULL if return code is NT_STATUS_OK.
