2013-03-26smbd: Remove an optimization that became unnecessaryVolker Lendecke1-7/+6
After we only collect nonlocal vnns in idx_state.vnns now, at this point we *know* we have something to send to a remote node. The previous code avoided the call to notify_push_remote_blob with an if-statement that has now become unnecessary.

2013-03-26smbd: We don't collect our own vnn anymoreVolker Lendecke1-3/+0
notify_trigger_index_parser will not anymore add ourselves into the vnn list that it collects. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Stefan Metzmacher <metze@samba.org>

We have a good chance that we did not collect any remote vnns. This avoids trying to walk the remote vnns altogether. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Stefan Metzmacher <metze@samba.org>

2013-03-26smbd: Avoid some talloc_realloc in notify_internalVolker Lendecke1-6/+16
For the nonclustered case we will only ever have one vnn in notify_index.tdb. For this case, without this patch we did talloc_realloc when collecting vnns to be able to do the memcpy instead of explicit copy with a for-loop. This new code will partition the new vnns we see when parsing a notify_index.tdb record into ourselves and all foreign vnns, only really collecting the foreign ones in an array.

2013-03-26smbd: Avoid sending 0-sized keys to dbwrapVolker Lendecke1-1/+8
Start the notification one level below /. Sharing and notifying / for changes is broken at this moment anyway. When sharing / and someone wants to get notified for changes under /usr, we store "//usr" as the notify_index key. So this patch does not break anything that is not broken today, and it avoids a bogus call to dbwrap_parse_records.

2012-06-27s3-param: Rename loadparm_s3_context -> loadparm_s3_helpersAndrew Bartlett1-1/+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.

2012-04-19s3: Fix Coverity ID 2747: FORWARD_NULLVolker Lendecke1-1/+1
For the notify cleanup process we have a notify context without a messaging entry. We will never call notify_add/remove for this, but the code should protect against this.

2012-04-18s3-dbwrap: push lp_ctx up another layer in the stackAndrew Bartlett1-1/+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

2012-03-10tdb_wrap: Move to specific directory.Jelmer Vernooij1-1/+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).

2012-01-18s3: Add a "lock_order" argument to db_openVolker Lendecke1-2/+4
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.
2011-10-13lib/util: Add back control of mmap and hash size in tdb for top level buildAndrew Bartlett1-2/+11
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

2011-06-20tdb_compat: Higher level API fixes.Rusty Russell1-1/+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>

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

2010-09-27Change to using TDB_INCOMPATIBLE_HASH (the jenkins hash) on allJeremy Allison1-4/+4
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.
