regdb_fetch_values_internal()
2012-04-25s3:registry: fix seqnum race in regdb_fetch_keys_internalMichael Adam1-3/+22
This prevents race between fetching seqnum and key content. Because there is currently no way to atomically fetch the record along with the seqnum, I use a loop. This is far from optimal and should should ideally be done differently. But for now it fixes the race. Signed-off-by: Andreas Schneider <asn@samba.org>

2012-04-25s3:registry: update the seqnum in the subkey cache at the end of ↵Michael Adam1-1/+5
regval_store_keys The purpose is to prevent next reads from going to disk. Note that this will currently only be effective with local tdbs, not with ctdb: For tdb, store and delete bump the seqnum while transaction commit does not. For ctdb, transaction commit bumps the seqnum, while store and delete don't... This needs fixing (in ctdb). Signed-off-by: Andreas Schneider <asn@samba.org>
2012-04-25s3:registry:db: update the value container seqnum after storing/deleting to ↵Michael Adam1-1/+22
prevent next read from going to disk if possible Note that this will currently only be effective in the local TDB implementation. For CTDB, this wont work since seqnum currently works differently there (needs fixing): For tdb, store and delete operations bump the db seqnum, while transaction commits don't. For ctdb, the seqnum is bumped by the transaction commit but not by store and delete operations. Signed-off-by: Andreas Schneider <asn@samba.org>

2012-01-18s3: Add a "lock_order" argument to db_openVolker Lendecke1-3/+6
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.

2011-12-03s3:registry: do not use regdb functions during db upgradeGregor Beck1-55/+141
It is importante to not use the database backend implementation in the upgrade. Otherwise this would only work as long as this is the newset version. In future versions of the registry, this (then) intermediate upgrade step would change in behaviour and not work as expected any more. Signed-off-by: Michael Adam <obnox@samba.org>

incomlete keys Originally, this function did not create the key's subkey list record if only the record was listed in the subkeylist of its parent key. Now this is fixed. Pair-Programmed-With: Gregor Beck <gbeck@sernet.de>
2011-10-11s3:dbwrap: convert dbwrap_fetch_int32() to NTSTATUS return codeMichael Adam1-4/+11
Return the int32 value retrieved from the db by reference. Before this, return value "-1" was used as a error indication, but it could also be a valid value from the database.

2011-08-25s3:registry: hand db context in to v2_to_v3 upgrade code via private_dataMichael Adam1-4/+9
This also fixes the earlier faulty handing in of a useless stackframe memory context via private_data.
2011-08-25s3:registry: fix broken use of dbwrap store record in v1_to_v2 upgrade codeMichael Adam1-8/+10
This also fixes broken private_data parameter for the traverse function (making use of it): Originally a memory context was handed in but was not used.

4-byte subkey counter More precisley, we return false if the record does not match the required structure of a leading 4-byte subkey counter followed by the corresponding number zero-terminated strings.
