The original patch I proposed in
Enhancements?id=6194;selectid=6194 is roughly compatible with mozldap.

So, what do folks think about reviving libldif as an exported piece of the
Exporting LDIF parsing sounds fine. Hopefully compatible with existing
libldifs (mozldap libldif and maybe very-old openldap libldif), though I
haven't looked at either yet.
I would prefer this approach - it would be most convenient to have the
LDIF parsed into LDAPMod and LDAPControl structures - for those (very
few?) apps that will want to use libldif standalone, it's easy to free
LDAPMod and LDAPControl structure data.
I can't decide what I think about dependencies. The way OpenLDAP libs
are split up in liblber and libldap is geting in the way, as usual.
For an app without LDAP/networking, it can be annoying to have to drag
in libldap and via that OpenSSL, SASL, which can drag in Berkeley DB,
and I don't know what else, just to parse LDIF files. When they're all
already installed I suppose it rarely matters much nowadays, but it may
be a different story for maintaining/downloading precompiled packages.
I think this could be accomplished in one of two ways:
1) Just have libldif return lists of struct berval* for the various data
parsed. The caller would be responsible for turning these into LDAPMod
or LDAPControl structures - the advantage is that libldif doesn't have
to know about any of these higher level structures
That sounds nice in making libldif almost standalone - needs only
liblber. For that matter, if someone wants to get rid of that we
could provide hooks for allocation and log functions.
2) Have libldif create LDAPMod and LDAPControl - I think this could be
accomplished by having ldif.c #include<ldap.h> to pull in the
definitions of LDAPMod and LDAPControl - would this be ok?
Does this need libldap? Or will it be sufficient to tell the user
that he should use ldap_controls_free() or functions he can copy&paste
from libldap, so he can avoid libldap if he really wants to?
Let's move this discussion to the openldap-devel mailing list. I'm
thinking (2) is OK but I'd like to hear from other developers /
potential users of this library.
