Providing LDIF support at the LDAP level
This patch provides low level LDIF support in libldif and high level
support in libldap.
http://rmeggins.fedorapeople.org/newldif.patch
http://rmeggins.fedorapeople.org/ldifutil.c
The libldap support is in the form of
LDAP_F( int )
ldap_parse_ldif_record LDAP_P((
char *rbuf,
int linenum,
LDIFRecord *lr,
const char *errstr,
unsigned int flags,
void *ctx ));
Where rbuf and linenum come from ldif_read_record; lr is new (see
below); errstr is the string prefix to print for error/debug messages
(usually the program name e.g. "ldapmodify"), flags are one of these:
#define LDIF_DEFAULT_ADD 0x01 /* if changetype missing, assume LDAP_ADD */
#define LDIF_ENTRIES_ONLY 0x02 /* ignore changetypes other than add */
#define LDIF_NO_CONTROLS 0x04 /* ignore control specifications */
and ctx is the memory context (for ber_*alloc_x)
LDIFRecord returns all of the data from the LDIF record, regardless of
what type of operation it is. The lr_op field is used to determine the
type of operation, and the other fields return the operation specific
data. There is also a section of several data fields used by the
internal implementation (lifted almost verbatim from ldapmodify.c).
This is cleaned up properly by ldap_ldif_record_done()
If the LDIF record in rbuf contains no actual record (e.g. the version:
field, comments only, etc.) then the return value of
ldap_parse_ldif_record() will be 0, but the lr_op field will also be 0.
