Re: (ITS#6489) Incomplete Master/Slave Replication
by frank.offermanns＠caseris.de 23 Jul '10

23 Jul '10

Hello Quanah, thanks for your info. I compiled OpenLDAP 2.4.23 and BDB 4.8.30, but unfortunately the problem still persists. I added 10000 Users added and: with RefreshAndPersist in 136 users at least one attribute was missing. with RefreshOnly in 34 users at least one attribute was missing. In my post in March I said, that with accesslog I do not have this problem. This is not completely true. Meanwhile (also with 2.4.21) I found out that with accesslog I also have this problem, but less frequentely. So with about 40000 users added I had only about 1 or 2 attributes missing. With the new version I added 10000, 20000 and 80000 users without a single problem. So I am not sure, if this problem still persist with accesslog, but with RefreshAndPersist and RefreshOnly there is definitely still a problem. Due to the fact that no one else complains about this, maybe this problem is Windows only? Or is there someone else who also has this problem? If you are interested I could provide you my windows test-application. With this the problem can be reproduced in a few minutes. Let me know if I should send you this program. Thanks a lot so far.

BDB 4.8.26 is known problematic. Please use BDB 4.8.30, and OpenLDAP 2.4.23, and report back if you still have issues.

There have been some fixes around deletes since 2.4.21, and an issue that was introduced in 2.4.21 specific to cached objects as well.

Hi Howard, > ==> I'm pretty sure there is a bug in HEAD (either in CVS or in my > HEAD). ;-) This ITS can be closed - the bug was in my head rather than in CVS head (background information: unresolved cvs update conflicts). I'm sorry for the inconveniences! Best regards, Daniel

All differences I can currently see: I'm using "hdb" and I use "grep -r -i 'olcDbConfig' slapd.d/" to test whether olcDbConfig does exist in any file below slapd.d. As the contents of an existing DB_CONFIG file (within the database-dir) will be converted correctly into olcDbConfig here, are you sure you had no "DB_CONFIG" file in your database directory? Could you please provide me the (original) slapd.conf you've used above? Than I would like to reproduce your exact test procedure here. ==> I'm pretty sure there is a bug in HEAD (either in CVS or in my HEAD). ;-)

I've checked 2.3.43 and 2.4.23; in both cases ber_int_sb_close() is being called twice on the same sockbuf.

If you want to be able to distinguish results based on scope then it makes more sense to just define a Search control. Like No-op - count the entries that would be returned, instead of returning them.
