* dbwrap: add a dbwrap_flags argument to db_open_ctdb()Michael Adam2014-02-071-1/+1
| | | | | | | | This is in preparation of directly supporting ctdb read only record copies when opening a ctdb database from samba. Signed-off-by: Michael Adam <obnox@samba.org> Reviewed-by: Stefan Metzmacher <metze@samba.org>
* dbwrap: add a dbwrap_flags argument to db_open()Michael Adam2014-02-071-1/+2
| | | | | | | | | | This is in preparation to support handing flags to backends, in particular activating read only record support for ctdb databases. For a start, this does nothing but adding the parameter, and all databases use DBWRAP_FLAG_NONE. Signed-off-by: Michael Adam <obnox@samba.org> Reviewed-by: Stefan Metzmacher <metze@samba.org>
* s3-param: Rename loadparm_s3_context -> loadparm_s3_helpersAndrew Bartlett2012-06-271-1/+1
| | | | | | | | | | | | | | | | | This helps clarify the role of this structure and wrapper function. The purpose here is to provide helper functions to the lib/param loadparm_context that point back at the s3 lp_ functions. This allows a struct loadparm_context to be passed to any point in the code, and always refer to the correct loadparm system. If this has not been set, the variables loaded in the lib/param code will be returned. As requested by Michael Adam.

* dbwrap: dbwrap_local_open()Rusty Russell2012-06-221-3/+3
| | | | | | | | This simply opens a tdb: it will eventually switch depending on the extension. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
* s3-dbwrap: push lp_ctx up another layer in the stackAndrew Bartlett2012-04-181-1/+4
| | | | | | | | | | This will allow db_open_tdb() to be called from common code, which may already have a loadparm context loaded. It also slowly moves the lp_ctx up the stack, as required to remove the library loop between smbconf and the registry. Andrew Bartlett

* s3: Enforce a lock order in dbwrapVolker Lendecke2012-01-181-0/+3
| | | | | | | 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: Add a "lock_order" argument to db_openVolker Lendecke2012-01-181-2/+17
| | | | | | | This will be used to enforce a lock hierarchy between the databases. We have seen deadlocks between locking.tdb, brlock.tdb, serverid.tdb and notify*.tdb. These should be fixed by refusing a dbwrap_fetch_locked that does not follow a defined lock hierarchy.
