* 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.

* tdb_wrap: Move to specific directory.Jelmer Vernooij2012-03-101-1/+1
| | | | | | | | | | It's a bit confusing to mix low-level and high-level libraries. We had multiple libraries in one directory, and there were have circular dependencies with other libraries outside that directory (in this case, samba-hostconfig).

* s3: Add a "lock_order" argument to db_openVolker Lendecke2012-01-181-1/+2
| | | | | | | 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.
* s3-dbwrap: Make dbwrap_parse_record return NTSTATUSVolker Lendecke2011-12-151-4/+6
| | | | | | | 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-ctdb: Make use of CTDB_CONTROL_CHECK_SRVIDSVolker Lendecke2011-11-301-0/+13

* lib/util: Add back control of mmap and hash size in tdb for top level buildAndrew Bartlett2011-10-131-1/+10
| | | | | | | | This passes down a struct loadparm_context to allow these parameters to be checked. This may be s3 or s4 context, allowing the #if _SAMBA_BUILD_ macro to go away safely. Andrew Bartlett
* s3:serverid: convert to using dbwrap wrapper functions onlyMichael Adam2011-10-111-16/+24
| | | | Avoid direct use of the db_record and db_context structs.
* s3:serverid: use dbwrap_traverse_read() in serverid_traverse_read()Michael Adam2011-10-111-1/+5
| | | | | | This also fixes the return value: originally the int return value of traverse_read which is a count of the records traversed or negative upon failure, was simply casted into a bool return value.
* s3:serverid: use dbwrap_traverse() in serverid_traverse()Michael Adam2011-10-111-1/+4
| | | | | | This also fixes the return value: Originally, the int returned by the traverse method, which is the count of the traverse was casted into a bool return value.

* Re-arrange the optimization to reduce tdb fcntl calls if smbd is notIra Cooper2011-08-201-1/+5
| | | | | | | | clustered. procid_is_me() is much cheaper to test and can optimize up to 50% of the calls to serverid_exists(). Volker please check. Autobuild-User: Jeremy Allison <jra@samba.org> Autobuild-Date: Sat Aug 20 01:15:07 CEST 2011 on sn-devel-104

* s3:dbwrap: move db_open() to a file dbwrap_open.c of its own.Michael Adam2011-07-291-0/+1
| | | | | | Also start new folder lib/dbwrap/ where dbwrap_open.c is stored and make the fallbacke implementation functoins non-static and create a dbwrap_private.h header file that contains their prototypes.
* tdb_compat: Higher level API fixes.Rusty Russell2011-06-201-1/+1
| | | | | | | | | | | | My previous patches fixed up all direct TDB callers, but there are a few utility functions and the db_context functions which are still using the old -1 / 0 return codes. It's clearer to fix up all the callers of these too, so everywhere is consistent: non-zero means an error. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
* s3-server_id Add task_id to server_id to match Samba4Andrew Bartlett2011-06-091-0/+3
| | | | | | | | | | This will allow this structure to be shared, and allow us to create a common messaging system between all Samba processes. Samba4 uses the task_id to indicate the different tasks within a single unix process. Andrew Bartlett Signed-off-by: Andrew Tridgell <tridge@samba.org>

* lib/util Move source3 tdb_wrap_open() into the common code.Andrew Bartlett2011-05-061-0/+1
| | | | | | | | | This #if _SAMBA_BUILD == 3 is very unfortunate, as it means that in the top level build, these options are not available for these databases. However, having two different tdb_wrap lists is a worse fate, so this will do for now. Andrew Bartlett

* s3: Fix serverid_existsVolker Lendecke2010-12-191-0/+4
| | | | | | | In the cluster case it can happen that a node just died and we did not yet have the time to clean up serverid.tdb. If the corresponding serverid.tdb record that represented a process was migrated away from the dead record, it represents existence of a process where it is already dead.
* Change to using TDB_INCOMPATIBLE_HASH (the jenkins hash) on allJeremy Allison2010-09-271-2/+2
| | | | | | | | | | TDB_CLEAR_IF_FIRST tdb's. For tdb's like gencache where we open without CLEAR_IF_FIRST and then with CLEAR_IF_FIRST if corrupt this is still safe to use as if opening an existing tdb the new hash will be ignored - it's only used on creating a new tdb not opening an old one. Jeremy.
* s3: Remove talloc_autofree_context() from serverid_db()Volker Lendecke2010-09-261-2/+2
