Hi John, I'm working on putting together OpenLDAP 2.3.42 release, so I was wondering if you've seen any ill effects from this patch.

Nothing else uses slapd-deltasync-slave.conf and it's not glued either. It shouldn't, but I'll read the test more to see why it's needed ;-) Gavin.

(ITS#5481) slapd 2.4.8+ with back-meta crashes when doing ldapsearch
by ali.pouya＠free.fr 21 Apr '08

21 Apr '08

Full_Name: Ali Pouya Version: 2.4.8+ OS: Linux 2.6 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (145.242.11.4) Hi, I'm trying to upgrade to back-meta 2.4.8+ I do my tests with the HEAD extracted on april 9. When searching SOME entries slapd core dumps with the following back trace : (gdb) bt #0 0x00dc17a2 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2 #1 0x006d07a5 in raise () from /lib/tls/libc.so.6 #2 0x006d2209 in abort () from /lib/tls/libc.so.6 #3 0x006c9d91 in __assert_fail () from /lib/tls/libc.so.6 #4 0x080a1bad in modify_add_values (e=Variable "e" is not available. ) at mods.c:64 #5 0x080d9966 in meta_back_search (op=0x905d4f8, rs=0xa2b691c0) at search.c:2049 #6 0x08061bbf in fe_op_search (op=0x905d4f8, rs=0xa2b691c0) at search.c:368 #7 0x08061315 in do_search (op=0x905d4f8, rs=0xa2b691c0) at search.c:217 #8 0x0805ff3a in connection_operation (ctx=0xa2b692a0, arg_v=0x905d4f8) at connection.c:1084 #9 0x0806060e in connection_read_thread (ctx=0xa2b692a0, argv=0xb) at connection.c:1211 #10 0x0814d149 in ldap_int_thread_pool_wrapper (xpool=0x8fb2cf0) at tpool.c:663 #11 0x00116371 in start_thread () from /lib/tls/libpthread.so.0 #12 0x00770ffe in clone () from /lib/tls/libc.so.6 (gdb) The target server is an OpenLdap 2.3.34 managed by another team (I cannot modify the entries). The end of the detailed slapd log file is reproduced below. It shows that the problem happens at the end of handling of the received data. Some more precisions : If I specify the attribute names (even all of them) ldapsearch is successfull ! The problem ONLY happens if I do not specify any attribute name. ldapsearch using directly the target server (or through back-meta 2.3.7) is also successfull.

(ITS#5480) Two object deletions missed in sync replication after daemons restarted
by marian.eichholz＠freenet.ag 21 Apr '08

21 Apr '08

Full_Name: Marian Eichholz Version: HEAD-20080411 OS: linux 2.6.23.13 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (194.97.7.65) Like in ITS#5371 we again missed two object deletions, approx. 4 minutes after provider and consumer were restarted (after stopped for a slapcat). This is too bad, because the cvs source from 20080411 at least is far more robust in terms of connection management than the release of openldap-2.4.8 (see ITS#5463) We now had full debug log on (any), and as far as I can see there is no obvious rejections or any other reason, why this deletions were not replicated to the two consumers. There were heading and trailing deletions in the same second, and I cannot see structural anomalies in the residual objects. The consumer databases were cloned from the provider after the incident that lead to ITS#5371. When we checked the consistency on Friday morning, the databases were identical, measured by the set of "dn:"-records in the dump. Of course we first stopped the provider, then the consumers. When we (re-) start the LDAP services, we first start the provider, then the consumers. Any idea how we can debug the problem or can get a realiable release? When needed and useful, I can provide a (heavily edited, for privacy reasons) excerpt from the debug log of the given second. Thank You in advance! - Marian Eichholz
