This is * complicated by objectclass inheritance and auxiliary classes though. * * Attributes must only occur in a single table. For objectclasses that inherit * from other classes, attributes defined in the superior class are only stored * in the superior class' table. When multiple unrelated classes define the same * attributes, an attributeSet should be defined instead, containing all of the * common attributes. * * The no_set table lists which other attributeSets apply to the current * objectClass. The no_attrs table lists all of the non-inherited attributes of * the class, including those residing in an attributeSet. * * Usually the table is named identically to the objectClass, but it can also * be explicitly named something else if needed. */ #define NDB_MAX_OCSETS 8 struct ndb_attrinfo; typedef struct ndb_ocinfo { struct berval no_name; /* objectclass cname */ struct berval no_table; ObjectClass *no_oc; struct ndb_ocinfo *no_sets[NDB_MAX_OCSETS]; struct ndb_attrinfo **no_attrs; int no_flag; int no_nsets; int no_nattrs; } NdbOcInfo; #define NDB_INFO_ATLEN 0x01 #define NDB_INFO_ATSET 0x02 #define NDB_INFO_INDEX 0x04 #define NDB_INFO_ATBLOB 0x08 typedef struct ndb_attrinfo { struct berval na_name; /* attribute cname */ AttributeDescription *na_desc; AttributeType *na_attr; NdbOcInfo *na_oi; int na_flag; int na_len; int na_column; int na_ixcol; } NdbAttrInfo; typedef struct ListNode { struct ListNode *ln_next; void *ln_data; } ListNode; #define NDB_IS_OPEN(ni) (ni->ni_cluster != NULL) struct ndb_info { /* NDB connection */ char *ni_connectstr; char *ni_dbname; Ndb_cluster_connection **ni_cluster; /* MySQL connection parameters */ MYSQL ni_sql; char *ni_hostname; char *ni_username; char *ni_password; char *ni_socket; unsigned long ni_clflag; unsigned int ni_port; /* Search filter processing */ int ni_search_stack_depth; void *ni_search_stack; #define DEFAULT_SEARCH_STACK_DEPTH 16 #define MINIMUM_SEARCH_STACK_DEPTH 8 /* Schema config */ NdbOcInfo *ni_opattrs; ListNode *ni_attridxs; ListNode *ni_attrlens; ListNode *ni_attrsets; ListNode *ni_attrblobs; ldap_pvt_thread_rdwr_t ni_ai_rwlock; Avlnode *ni_ai_tree; ldap_pvt_thread_rdwr_t ni_oc_rwlock; Avlnode *ni_oc_tree; int ni_nconns; /* number of connections to open */ int ni_nextconn; /* next conn to use */ ldap_pvt_thread_mutex_t ni_conn_mutex; }; #define NDB_MAX_RDNS 16 #define NDB_RDN_LEN 128 #define NDB_MAX_OCS 64 #define DN2ID_TABLE "OL_dn2id" #define EID_COLUMN 0U #define VID_COLUMN 1U #define OCS_COLUMN 1U #define RDN_COLUMN 2U #define IDX_COLUMN (2U+NDB_MAX_RDNS) #define NEXTID_TABLE "OL_nextid" #define NDB_OC_BUFLEN 1026 /* 1024 data plus 2 len bytes */ #define INDEX_NAME "OL_index" typedef struct NdbRdns { short nr_num; char nr_buf[NDB_MAX_RDNS][NDB_RDN_LEN+1]; } NdbRdns; typedef struct NdbOcs { int no_ninfo; int no_ntext; int no_nitext; /* number of implicit classes */ NdbOcInfo *no_info[NDB_MAX_OCS]; struct berval no_text[NDB_MAX_OCS]; struct berval no_itext[NDB_MAX_OCS]; /* implicit classes */ } NdbOcs; typedef struct NdbArgs { Ndb *ndb; NdbTransaction *txn; Entry *e; NdbRdns *rdns; struct berval *ocs; int erdns; } NdbArgs; #define NDB_NO_SUCH_OBJECT 626 #define NDB_ALREADY_EXISTS 630 LDAP_END_DECL #include "proto-ndb.h" #endif
