* dbwrap_watch: Remove the "prec" parameter from watch_recvVolker Lendecke2017-11-291-2/+1
| | | | | | | | | | | The initial idea was to have some "atomicity" in this API. Every caller interested in a record would have to do something with it once it changes. However, only one caller really used this feature, and that is easily changed to not use it. So remove the complexity.

* dbwrap: Add an alternative implementation of dbwrap_watch_record_sendVolker Lendecke2016-07-151-9/+12
| | | | | | | | | | | | | | | The existing one with a separate dbwrap_watchers.tdb turns out to create a performance penalty in a clustered environment. Non-clustered, dbwrap_parse_record on non-existent records is very cheap, but in a cluster environment this is very noticable. This implementation puts the watcher information into the records itself. For large records, this might be another performance penalty, because we have to assemble the final record together with talloc and memcpy, but this might be fixed later with a tdb_storev call.

* dbwrap: Add "blocker" to record_watch_sendVolker Lendecke2016-07-151-2/+4
| | | | | | | | | | Typicall, when we watch a record, we wait for a process to give up some resource. Be it an oplock, a share mode or the g_lock. If everything goes well, the blocker sends us a message. If the blocker dies hard, we want to also be informed immediately.

* 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>
