RE: (ITS#4864) -r option "redirects" to logfile, breaks replication
by Chris.Eubank＠gov.bc.ca 13 Mar '07

13 Mar '07

OK I understand if the -r switch (to slurpd, not slapd) redirects the output to a file for debugging purposes, this is just not apparent in the man pages. The man pages to not tell me that slurpd will be "redirecting" with the -r switch. It is just usual replication I was setting up originally. This is the variable I was using in an "openldaprc" file: # -r replication-log-file. Directory must be created. #SLURPD_REPL_LOG_FILE=/var/openldap-slurp/log When uncommenting this line, the result is that it does not open network connections to the replication slaves. _All_ data goes to the file, none to the slaves. This isn't documented correctly, it took me a long time to figure out why the replication was not happening.

Who sent the replication data to the logfile? slapd(8) is supposed to write replication data to the file specified in replogfile (sladp.conf(5)); slurpd(8) is supposed to read that file (whose existence and location is known by parsing slapd.conf(5)), copy the content it is able to process to its own replication log, which resides in slurpd's working directory (default or passed with -t) and is called slurpd.replog, send that content to the slaves, and remove the data that has been handled from slapd's replication log. This is how things are expected to work. As you may see, -r never comes into play; it's intended to be used to force slurpd processing of a different file, which may be required for special purposes. Do you have any special needs, or are you simply trying to set up usual replication? > Does that make more sense? See comments above. p. Ing. Pierangelo Masarati OpenLDAP Core Team SysNet s.n.c.

I'd keep it simple as it is now. OK. You'll find a new version here: ftp://ftp.openldap.org/incoming/raphael-ouazana-070313.patch It takes care of your notices. Regards, Raphael Ouazana.

I just want support for ";binary" both on storage and retrieval to be supported. I'll accept that it's obsolete -- I'll also put forth that a lot of things still use it (e.g. Lotus Domino v6). >> There remains an issue with selecting attributes using, e.g., >> "userCertificate;binary" -- nothing is returned.

The >attribute name is in ad_type->sat_cname. And, in fact, none of what I did appears to have been sufficient. I'm still looking at why selecting "userCertificate;binary" as part of an ldapsearch attribute-list doesn't pull the data. "userCertificate" does. The issue appears to be related to the ad_inlist verification on the search-supplied attribute -- "userCertificate;binary" doesn't resolve. If you know where I can look to figure this out, that would help. I've been through some areas and not found exactly where just yet. Thanks for your assistance.

(ITS#4872) Non-portable comparison in wait4msg() (result.c) causes infinite loop
by carsten.agger＠tietoenator.com 13 Mar '07

13 Mar '07

Full_Name: Carsten Agger Version: 2.3.20 OS: OSE URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (194.237.142.21) On our architecture (OSE running on an AXE processor), time_t is an unsigned int. This means that this code, as found in the wait4msg function in libraries/libldap/result.c, will break: > > if ( rc == LDAP_MSG_X_KEEP_LOOKING && tvp != NULL ) { > tmp_time = time( NULL ); > tv0.tv_sec -= ( tmp_time - start_time ); > if ( tv0.tv_sec <= 0 ) { > rc = 0; /* timed out */ > ld->ld_errno = LDAP_TIMEOUT; > break; > } > tv.tv_sec = tv0.tv_sec; > ... > } Why? Because if (start_time > tmp_time), the condition ( tv0.tv_sec <= 0 ) will never evaluate to TRUE, and the break will never be executed - yielding an infinite loop. Solution: rewrite in a portable way, e.g. (as suggested by Pierangelo Masarati on the bugs mailing list) by testing if the value of tv_sec would be negative after subtracting ( tmp_time - start_time ) before assigning it.

Bug causing infinite loop in result.c
by Carsten.Agger＠tietoenator.com 13 Mar '07

13 Mar '07

We have found a bug in libraries/libldap/result.c which may cause an infinite loop in some situations. The error is this, in the function wait4msg(): if ( rc == LDAP_MSG_X_KEEP_LOOKING && tvp != NULL ) { tmp_time = time( NULL ); tv0.tv_sec -= ( tmp_time - start_time ); if ( tv0.tv_sec <= 0 ) { rc = 0; /* timed out */ ld->ld_errno = LDAP_TIMEOUT; break; } tv.tv_sec = tv0.tv_sec; ... } The problem is this: The check ( tv0.tv_sec <= 0 ) is always true, since tv_sec (on our system, at least) is an unsigned int. The problem is fixed by casting it to int: if ( (int) tv0.tv_sec <= 0 ) { ... } however this might not be the most suitable way to fix it. best regards, Carsten Agger Software Consultant, TietoEnator A/S, Denmark http://www.tietoenator.dk

(ITS#4871) index directive & slapd.conf(5)
by quanah＠stanford.edu 12 Mar '07

12 Mar '07

Full_Name: Quanah Gibson-Mount Version: 2.3/2.4/HEAD OS: NA URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (171.66.155.86) The slapd.conf(5) man page talks about the various ways in which indices can be tuned, such as index_substr_if_maxlen, but it does not actually mention the index directive. It may be worthwhile to have text like [b]index[/b] See the man page for the specific backend you are using for more information about the index directive {ex: slapd-bdb(5)} so that users can more easily find that information (and the necessity to run slapindex on bdb, for example) etc.

If you report the behavior as satisfactory, backporting to re23 could be an option, since the fix should be well isolated, and it configures as borderline between new feature and bug fix. p. Ing.
