commit de8a339cdf95f6737a8b1d34aa2aa9287bae0e46
Author: Matthias Dieter Wallnöfer <mdw at samba.org>
Date: Tue Jun 29 16:10:32 2010 +0200
s4:registry - move some common constraint checks to the "local" backend
They should also be enforced when we don't use "ldb".
commit d81e2af69de4401335681d859c44b2c30fb4456c
Author: Matthias Dieter Wallnöfer <mdw at samba.org>
Date: Tue Jun 29 18:27:49 2010 +0200
s4:lib/registry/tests/registry.c - test recursive key generation
commit ae50385d524d8cb4831d8eb0c45feb4d04437f28
Author: Matthias Dieter Wallnöfer <mdw at samba.org>
Date: Tue Jun 29 18:08:47 2010 +0200
s4:registry - on key add operations we have to handle with paths not always only a name
Recursive key generations are allowed.
commit 781ea5be1399de8abe201ab239d3915331264deb
Author: Matthias Dieter Wallnöfer <mdw at samba.org>
Date: Tue Jun 29 15:45:37 2010 +0200
s4:lib/registry/local.c - support recursive key generation
Code taken from "local_open_key".
commit 809c74790006c985ac64eb7823a4a450498c832f
Author: Matthias Dieter Wallnöfer <mdw at samba.org>
Date: Thu Jun 24 21:12:19 2010 +0200
s4:lib/registry/ldb.c - refactor "reg_path_to_ldb"
This makes it easier to understand and would also support splitting in more
DN components.
commit 50ae292e60e53275f87ad2281b25eda34d0af59c
Author: Matthias Dieter Wallnöfer <mdw at samba.org>
Date: Tue Jun 29 17:37:45 2010 +0200
s4:lib/registry/ldb.c - use "ldb_path" rather than "ldap_path" as LDB key varibale identifiers
commit d0e877e785f6463dadbb973bc42174674cbdbad2
Author: Matthias Dieter Wallnöfer <mdw at samba.org>
Date: Tue Jun 29 15:52:19 2010 +0200
s4:lib/registry/ldb.c - "ldb_add_key" - fix talloc handling
- free "msg" when possible
- prevent "talloc_strdup"s where not necessary
