And again, I have not changed anything in this code and have been adding things like this for the past 2 years with OpenLDAP 2.2 and earlier. I mean sure I can go edit my code to add those ou's and ncsucurriculumcodes in the correct order (ie, bunched together), but if you are saying openldap should be able to handle this, I'd like to stick with it and see it resolved instead of letting it be a dangling difference behavior since 2.2. If you want to make an official-like statement that what I'm doing there is not proper and not supported, then so be it, I'll take that as golden and adjust my code. =) (in other words, would you rather it be that this is flat out not supported? .. of course if it's not supported it would be nicer if openldap yelled about it instead of accepting it and just being mad afterwards) I moved away from 2.2 because it looks like you all don't support it anymore and I started running into stability problems. (which we have not narrowed down to be OpenLDAP's 'fault'.. just upgrading OpenLDAP was a good first and easy step 1, and actually seems to have helped) Daniel > -- > -- Howard Chu > Chief Architect, Symas Corp. http://www.symas.com > Director, Highland Sun http://highlandsun.com/hyc > OpenLDAP Core Team http://www.openldap.org/project/ >

Recall from http://www.openldap.org/lists/openldap-devel/200701/msg00077.html the trick to keep the consumer from starting only works if the providerURI matches a listenerURI.

(ITS#4822) After test049 is over, restarting the producer dumps core
by ando＠sys-net.it 28 Jan '07

28 Jan '07

Full_Name: Pierangelo Masarati Version: HEAD OS: Linux 2.6 (CentOS 4.4) URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (81.72.89.40) Submitted by: ando After test049 is over, restarting the producer dumps core. This happens in the consumer's code (!) which, as far as I can understand, is there in cn=config only for the purpose of replicating to the consumer and set it to be, well, a consumer. Same happens when re-starting slapd with the consumer's database. The problem is related to the pending CSN being a NULL berval; the assertion occurs while trying to copy it, since the source of a ber copy cannot be NULL. If it is correct that pending CSN be NULL, the test must be performed before calling ber_bvreplace(); otherwise, this needs to be fixed. At this point I suggest that test049 includes stopping and restarting both (when this bug is fixed), re-checking that contents match. <producer> ...

Hi Howard! As much as I hate to say this, it did not solve the problem I was running into. =( I rebuilt openldap with the entry.c patch and rebuilt the LDAP database from scratch (pulling from sources and using slapadd).

I've plugged the config related leaks; what appears to be missing is the companion of connection_fake_init() that takes care of destroying the slab. BTW, there's a SLAPI-related connection_fake_destroy() which has nothing to do with the purpose... p.
