Difference between revisions of "Samba4 Port: hdb & ldb Interfaces"

Revision as of 18:11, 12 September 2009

This page aims to reduce the confusion about

1. two hdb interfaces (one for Samba4, one for heimdal);
2. Samba4's LDB interface, and
3. Samba4's ldb interface.

Heimdal's hdb Interface to LDB

source4/kdc/hdb-samba4.c contains the LDB_ functions, which only that file uses directly.

In Samba4's heimdal/lib/hdb/hdb.h, Heimdal's HDB structure contains "hdb-" prefixed function-pointers to the LDB functions. Only Heimdal uses this function-pointer interface to Samba4's LDB functions:

1. (HDB *)->hdb_dbc = NULL;
2. (HDB *)->hdb_open = LDB_open;
3. (HDB *)->hdb_close = LDB_close;
4. (HDB *)->hdb_fetch = LDB_fetch;
5. (HDB *)->hdb_store = LDB_store;
6. (HDB *)->hdb_remove = LDB_remove;
7. (HDB *)->hdb_firstkey = LDB_firstkey;
8. (HDB *)->hdb_nextkey = LDB_nextkey;
9. (HDB *)->hdb_lock = LDB_lock;
10. (HDB *)->hdb_unlock = LDB_unlock;
11. (HDB *)->hdb_rename = LDB_rename;
12. (HDB *)->hdb__get = NULL;
13. (HDB *)->hdb__put = NULL;
14. (HDB *)->hdb__del = NULL;
15. (HDB *)->hdb_destroy = LDB_destroy;

Samba4's hdb Interface

Samba4's heimdal/lib/hdb/hdb.c defines another set of hdb_ functions:

External entry-points:

1. hdb_next_enctype2key
2. hdb_enctype2key
3. hdb_free_key
4. hdb_lock
5. hdb_unlock
6. hdb_free_entry
7. hdb_foreach
8. hdb_check_db_format
9. hdb_init_db
10. hdb_list_builtin
11. hdb_createandlers

There are also some event-handlers (local fcns invoked via function-pointers):

1. hdb_ldb_free_entry in kdc/hdb-samba4.c
2. hdb_samba4_create in kdc/kdc.c

Heimdal-internal hdb interface

ldb interface

These routines are defined & used only in Samba4, and not in Samba4's heimdal snapshot tree.
