I don't understand why you would take the time to report a bug, but then refuse to provide the information necessary to fix it.

That's why I attached my patch which simply checks the return value, and prints out a log messge to notify users. The patch itself does not have any side effect to other part of code.

Re: (ITS#7450) segfault with listener-threads=8

Hi, Howard, Thanks for the explanation. Yes, it seems that I was confused by the numbers. I cannot reproduce the case when setting listener-thread as 8. It's possible that I confused myself by setting the number many times. I thought the number is to specify the listening threads but it seems my understanding was wrong.

Hi, Howard, GDB did stop at the statement: **assert( SLAP_SOCK_NOT_ACTIVE(id, s) );** But the system output is **Segmentation fault (core dumped)** It seems not related to whether it's a power of 2 or not, because even I specify it as 64, i.e., 2^6, the result and error message are still the same.

Expect poor performance for suffix "dc=xxx,dc=xxx". 50b1ca90 bdb_monitor_db_open: monitoring disabled; configure monitor database to enable 50b1ca90 slapd starting Segmentation fault (core dumped) The default configuration does not have this problem. So I checked every configuration setting I made and finally found it's caused by the following setting: listener-threads 8 Is this a bug?

The umlaut's are gone while posting. So i will try to describe: The search expression is "search<lower umlaut a>o<lower umlaut o>u...". This is converted to "SEARCH<lower umlaut a>O<lower umlaut o>U" in the SELECT statement. The expected is "SEARCH<upper umlaut a>O<upper umlaut o>U". -- Herbert Metzdorf

Full_Name: Herbert Metzdorf Version: 2.4.30 OS: Windows 7 / 2008 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (87.138.76.52) I am using thunderbird to query the openldap with the sql backend. Queries with german umlaut's give no result because of wrong lower/uppercase conversion. Look at the following log snippets: 50ab7cdb ==> limits_get: conn=1008 op=1 self="[anonymous]" this="ou=adressen,dc=geograt,dc=de" 50ab7cdb ==>backsql_search(): base="ou=adressen,dc=geograt,dc=de", filter="(|(?mail=*searchäoöuü*)(cn=*searchäoöuü*)(givenName=*searchäoöuü*)(sn=*searchäoöuü*))", scope=2,50ab7cdb deref=0, attrsonly=0, attributes to load: custom list 50ab7cdb ==>backsql_get_db_conn() ... 50ab7cdb <==backsql_srch_query() returns SELECT DISTINCT ldap_entries.id,ldap_persons.sysid,'inetOrgPerson' AS objectClass,ldap_entries.dn AS dn FROM ldap_entries,ldap_persons WHERE ldap_persons.sysid=ldap_entries.keyval AND ldap_entries.oc_map_id=? AND UPPER(ldap_entries.dn) LIKE CONCAT('%',UPPER(?)) AND (1=0 OR (UPPER(vorname||' '||nachname) LIKE '%SEARCHäOöUü%') OR (UPPER(vorname) LIKE '%SEARCHäOöUü%') OR (UPPER(nachname) LIKE '%SEARCHäOöUü%')) The search expression in converted to uppercase but this fails for the umlaut's. Is there a parameter to configure this behavior, or do you know a workaround? Thanks for your help Herbert

I'd regard slapadd to be in kind of a manage mode by default. E.g. it does not check constraints. And as said OBSOLETE attribute types are already accepted. Ciao, Michael.

Currently, slap_tool_entry_check() sets "manage" to 0 when calling entry_schema_check(); setting it to !0 would allow loading of OBSOLETE objectClasses. Maybe "manage" should be passed to slap_tool_entry_check(), and write tools (slapadd, slapmodify) could have an explicit '-o manage' option to enable handling of these cases. p. -- Pierangelo Masarati Associate Professor Dipartimento di Ingegneria Aerospaziale Politecnico di Milano

Full_Name: Michael Ströder Version: HEAD OS: URL: Submission from: (NULL) (79.227.170.198) Importing an LDIF file with slapadd which contains entries with an object class marked as OBSOLETE in the schema fails. Importing entries with OBSOLETE attribute types seems to work just fine. If object classes are marked as OBSOLETE it's clear that it should be impossible to add new entries via LDAP based on such an object class. But it should still be possible to restore old entries from backup.

(ITS#7445) slapo-deref: deref control should only be register when actually enabled
by rhafer＠suse.de 19 Nov '12

Full_Name: Ralf Haferkamp Version: HEAD, RE24 OS: SLES11 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (92.252.81.246) This is similar to ITS#6647 (which was about sssvlv). Support for the deref control should only be advertised in rootDSE when at least one instance of the deref overlay is present. Patch is on the way.

(ITS#7444) Check the return value of ldap_pvt_thread_set_concurrency
by tixu＠cs.ucsd.edu 17 Nov '12

Full_Name: Tianyin Xu Version: 2.4.33 OS: Ubuntu 12.04 (actually doesn't matter) URL: Submission from: (NULL) (2607:f720:1300:1241:590b:49c:889f:7b21) Hi, all, Still the verbosity idea. In the current version of slapd, when handling users' "concurrency" setting, slapd does not check the return value of "ldap_pvt_thread_set_concurrency" (essentially the return value of "pthread_setconcurrency") to see whether the setting is successful or not. So when the user setting is inappropriate (i.e., too big), slapd says nothing. But users have no way to be aware of such configuration failure. I suggest to check and notify users in this case. Here's the patch: --- ../openldap-2.4.33/servers/slapd/bconfig.c 2012-10-10 05:18:49.000000000 -0700 +++ servers/slapd/bconfig.c 2012-11-16 14:52:37.211421828 -0800 @@ -1530,7 +1530,14 @@ break; case CFG_CONCUR: - ldap_pvt_thread_set_concurrency(c->value_int); + + if(ldap_pvt_thread_set_concurrency(c->value_int) != 0) { + snprintf( c->cr_msg, sizeof( c->cr_msg ), + "concurrency=%d is not valid; using the default setting", + c->value_int ); + Debug(LDAP_DEBUG_ANY, "%s: %s.\n", c->log, c->cr_msg, 0 ); + + } break; case CFG_THREADS:
