The *.flt shows that an entry is missing on the slave. The slapd.1.log shows that the provider sent the entry. The slapd.4.log shows that the consumer received the entry and ignored it. (See slapd.4.log line 3307-3313. Compare with the previously received entry, lines 3161-3169.) The most puzzling part is that every code path in the consumer that rejects an entry logs an error message, and there is no error message in the log file. Without any means to reproduce this there's not much we can do. Setting a higher debug level might be useful, but any error messages in this path should have shown up regardless. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

(ITS#6381) connection_fake_init() from db_open() is unsafe
by hyc＠OpenLDAP.org 15 Nov '09

15 Nov '09

Full_Name: Howard Chu Version: 2.4 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (76.91.220.157) Submitted by: hyc Originally the db_open() handlers only ran from slapd's main context, at startup time before threading was active. But with back-config, backends and overlays can be added at runtime and the db_open() handler then runs in a back-config operation thread. If a db_open handler calls connection_fake_init() using its current thread context, it will get the current sl_malloc memory context as well, and reset it to zero. Any sl_mallocs called up to that point will be forgotten and they'll be overwritten by subsequent calls in that thread. We never saw any problems with this prior to ITS#6380, because the prior mallocs tended to be higher up in the sl_malloc heap. So even though the heap was reset, the new mallocs didn't collide with the old ones. This is already fixed in HEAD: back-sql/init.c, back-monitor/init.c, and overlays/{dds.c, pcache.c, syncprov.c}

(ITS#6380) slap_sl_free is too lazy
by hyc＠OpenLDAP.org 15 Nov '09

15 Nov '09

Full_Name: Howard Chu Version: 2.4 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (76.91.220.157) Submitted by: hyc slap_sl_free() would only reclaim memory if you were freeing the last allocated block. If you wanted to free a chain of alloc'd memory you would have to free them in the exact reverse order of allocation. Calling slap_sl_free() out of order would be a no-op. This was OK most of the time because a single operation would seldom live long enough to use much memory. But for long-lived tasks (like syncrepl or syncprov) it would often run out and allocs would fallback to ch_malloc. sl_malloc.c in HEAD has been changed to mark freed blocks no matter what order they're freed in. It still only reclaims from the last block forward, but it's more effective now.
