I see that tm->tm_usub is negative, there seems to be overflows between LARGE_INTEGER and int variables.

No. The C standard specifies that global and static variables are initialized to zero by default. If you're a C programmer you should know this already. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

That is not possible, nor is it supposed to be necessary with the way the syncrepl protocol was designed. During a refresh (which occurs at server startup time, at least) the consumer's context is not updated until all of the modified entries have been received. So, this particular comparison should never fail like this. > I precise that I have set the following directives (I have no delete operation > in my directory and I wish to avoid the present phase to be engaged) : > > syncprov-nopresent TRUE > syncprov-reloadhint TRUE > > If I comment out at least one of these directives then the problem disapears > (the object o1 is present in the replica). You're tripping over a behavior change that was made to fix ITS#5493. For now, you should only use both of those settings together if the underlying database is an accesslog DB (which always returns entries in modification order).

(ITS#5669) slapd replica ignores some new objects
by ali.pouya＠free.fr 26 Aug '08

26 Aug '08

Full_Name: Ali Pouya Version: 2.4.11 OS: Linux 2.6 (Fedora) URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (145.242.11.3) I have a directory with a master and one replica in RefreshAndPersist mode. The replica is synchronized with the master. I stop it for making a backup. During that time I do three write operations on the master : I add a new object o1, then I modify an already existing object o2, and finally I add another new object o3. After service startup, the replica gets synchronized with the master, and the contextCSN attributes are the same on both servers. But the object o1 is missing in the replica ! More investigation shows that the sync provider sends objects to the consumer in createTimestamp order. In other words the sync information is sent in this order : o2, then o1, then o3. After getting o2, the consumer rejects o1 (which has now a smaller entryCSN) with this message in the log: .... do_syncrep2: cookie=rid=002,csn=20080822130259.472005Z#000000#001#000000 do_syncrep2: rid=002 CSN too old, ignoring 20080822130259.472005Z#000000#001#000000 ldap_msgfree ... I think sync data would better be sent in entryCSN order rather than in createTimestamp order. I precise that I have set the following directives (I have no delete operation in my directory and I wish to avoid the present phase to be engaged) : syncprov-nopresent TRUE syncprov-reloadhint TRUE If I comment out at least one of these directives then the problem disapears (the object o1 is present in the replica). The environment and configuration files are the same as for ITS 5661. Of course I can provide any other information required. Best Regards Ali Pouya

(ITS#5668) Invalid entryCSN generated, and slapd will not restart
by emmanuel.duru＠atosorigin.com 26 Aug '08

26 Aug '08

Full_Name: Emmanuel Duru Version: 2.4.11 OS: Windows URL: Submission from: (NULL) (80.78.0.137) On Windows, slapd generates entryCSN values such as: 20080822124130.-657205Z#000000#000#000000 (the problem is the minus sign). This is also the case when generating the cn=config branch from a slapd.conf file. Following this, slapd will not restart, because it checks the validity of entryCSN values on cn=config branch at startup. I believe that the problem comes from non initialized static variables in lutil_gettime() function. Do notice that initializations are also missing in non WIN32 section.

Hi there, I've patched pcache.c and it seems fine. I'll put it through some more testing and confirm. Cheers Toby -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.
