2022-12-19smbd/locking: make use of the same tdb hash_size and flags for all SMB ↵Stefan Metzmacher1-6/+4
related tdb's It's good to have a consistent set of hash_size/flags for all aspects of an open file handle. Currently we're using 4 databases: smbXsrv_open_global.tdb, leases.tdb, locking.tdb and brlock.tdb. While at it also crank up the hashsize if the smbXsrv_tcon and smbXsrv_session TDBs. The default TDB hash size is insanely small and disk space is cheap these days, by going with the much larger hash size we get O(1) lookup instead of O(n) for moderate to large loads with a few thousand objects.

2019-11-22dbwrap: Pass "value" to dbwrap_do_locked() callbackVolker Lendecke1-2/+4
I want to reduce dbwrap_record_get_value(). It makes the caller believe it can make a copy of the TDB_DATA returned and that the value remains constant. It's not, as you can always do a dbwrap_record_store(). This patch removes one requirement for getting the value out of a db_record via dbwrap_record_get_value(). You can still make a copy, but from an API perspective to me it's more obvious that "value" as a parameter to the callback has a limited lifetime.
