(ITS#7643) MDB_cmp_func not properly documented
by vissermc＠gmail.com 24 Jul '13

24 Jul '13

Full_Name: Michiel Visser Version: 2.4.35 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (88.159.211.22) The MDB documentation must specify what is expected of MDB_cmp_func. I assume it must return -1,0,1 depending on the order, similar to ansi compare functions, but it is not trivial, nor all will know.

As far as I can tell there were two separate crashes related to syncrepl with slapi plugins enabled. The one I reported in ITS#7636 was constant and easily reproducible, therefore it somewhat masked the crash I have reported in this bug report. Should the two reports be merged even though the causes and backtraces are different?

Valgrind was used > specifically to aid in creating this bug report; it is not part of my normal > testing of this software. The output is puzzling. It shows syncprov_db_close accessing a persistent search structure that was already freed in syncprov_op_abandon. The puzzling part is that syncprov_db_close can only find ops by following the si->si_op list, and syncprov_op_abandon always removes ops from the si_op list before it frees anything. Will have to look into this later, but now you can see why this feature is not part of the public 2.4 releases. Nor will it be, it's a 2.5 feature. > ==2454== Memcheck, a memory error detector > ==2454== Copyright (C) 2002-2011, and GNU GPL'd, by Julian Seward et al. > ==2454== Using Valgrind-3.7.0 and LibVEX;

(ITS#7640) LDAP_OPT_CONNECT_ASYNC
by jeremy.hustache＠netasq.com 13 Jul '13

Full_Name: jeremy hustache Version: 2.4.31 OS: FreeBSD URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (46.218.228.130) I want to use ldap_simple_bind completely asynchronously (for the connect level and bind request). My code is the following: ldap_set_option(ld, LDAP_OPT_CONNECT_ASYNC, LDAP_OPT_ON); rc = ldap_simple_bind(ld, user, password); I set also options LDAP_OPT_NETWORK_TIMEOUT before calling ldap_simple_bind. rc is still equal to -1 and ldap_err2string(rc) returns "Can't contact LDAP server" If I call ldap_simple_bind without calling previously ldap_set_option(ld, LDAP_OPT_CONNECT_ASYNC, LDAP_OPT_ON), rc is successful. So can I use ldap_opt_connect_async in this case ?

Ignore my earlier noise please--an old (unpatched) libslapi library was present on the system from earlier debugging attempts, this was what caused the recent crash. Your patch seems to work! Thank you for your quick response; we now have a shot at going forward with the OpenLDAP deployment. Tim
