Re: (ITS#8521) Cannot have replication working after setting up the replication config in slapd.d

Actually, it's an invalid issue. The problem is all in teh sequence of updates on the provider. There are 6 possible scenario, depending on which order we inject the serverID, teh syncprov overlay and the data : 1) data, serverID, syncprov : invalid. All the data will have a wrong entryCSN 2) data, syncprov,serverID : invalid, same reason 3) serverID, syncprov, data : All work properly 4) syncprov, serverID, data : All work properly 5) serverID, data, syncprov : the corner case scenario... Syncprov has no way to know which contextCSN to generate. The only way for the server to replicate is to do an update, so that the contextCSN is properly generated. 6) syncprov, data, serverID : invalid. All the data will have a wrong entryCSN Bottom line, *always* inject the serverID and syncprov *before injecting some data, or be ready to do an update after having injected syncprov and serverID. =20 Le 21/10/16 =C3=A0 23:45, openldap-its(a)OpenLDAP.org a =C3=A9crit : > *** THIS IS AN AUTOMATICALLY GENERATED REPLY *** > > Thanks for your report to the OpenLDAP Issue Tracking System.

FTR, the check on slapd_serverID presence has been added in ITS#8281.

The problem is that if we already have a ServerID on the producer, it will never generate a contextCSN, waiting for the consumer to send one, or for an update to occur : static int syncprov_db_open( BackendDB *be, ConfigReply *cr ) { ... /* Didn't find a contextCSN, should we generate one? */ if ( !si->si_ctxcsn ) { char csnbuf[ LDAP_PVT_CSNSTR_BUFSIZE ]; struct berval csn; if ( slap_serverID || SLAP_SYNC_SHADOW( op->o_bd )) { /* If we're also a consumer, then don't generate anything. * Wait for our provider to send it to us, or for a local * modify if we have multimaster. */ goto out; } At this point, nothing happens when teh consumer connects for teh very first time, because it is expected to send a contextCSN, which it obviously don't have. I do think that the provider should always generate a contextCSN for its own data, when the syncprov overlay is added. that should solve the problem. Now, I don't know (yet) what would be the impact on replication if we do so. Still investigating... -- Emmanuel Lecharny Symas.com directory.apache.org

Re: (ITS#8537) liblmdb errors with data=NULL and non-matching SET_KEY
by h.b.furuseth＠usit.uio.no 01 Dec '16

Related issue: mdb_cursor_prev/mdb_cursor_last() with data==NULL position the xcursor at 1st data item, while data!=NULL puts it at last item. That's unintuitive and should either be documented or normalized - but changing it can break existing programs. In the cases when it didn't just fail earlier, anyway: mdb_cursor_prev(), and maybe mdb_cursor_last() on a sub-DB. Haven't tested the latter. Whatever mdb_cursor_last() ends up doing, I think mdb_cursor_prev() should do the same. There is positioning code inside if(data) elsewhere too, but defaults to doing cursor_first() or something similar. Don't know if that can have any visible effect on the next operation. -- Hallvard

Then try to use the cursor in another operation. Test program enclosed.
