asserts and manadatory build instructions (was ITS#8240)

But this is the first time I've heard about -DNDEBUG being mandatory when compiling binary packages for production use. Does it have other effects? And what are general rules for assert statements in OpenLDAP code? In my own (Python) code assert statements are supposed to be only triggered if something goes wrong *internally* (type issues etc.). If somebody manages to trigger an assert statement with invalid input from "outside" I always consider this to be a serious bug revealing insufficient error handling even though e.g. web2ldap just logs the exception but won't crash. YMMV, but please clarify. I also wonder whether there are more mandatory rules for building packages and where I can find them. Please don't get me wrong: My inquiry is in good faith to avoid unnecessary ITS based on misunderstanding. Ciao, Michael.

(Mea culpa, I accidentally hit "reply" instead of "reply all". Sorry. Now reposting to the mailing list.) Since we only need to do this on Windows, we could use MultiByteToWideChar with CP_UTF8. (That's what TO_TSTRING does, too.) I do not think we would ever need to do any such conversion on UNIX. https://msdn.microsoft.com/en-us/library/windows/desktop/dd319072%28v=vs.85… I'm not sure if we can just copy-paste BDB's code. Probably not, that would lead to licensing issues, wouldn't it?

Re: Dropping the MozNSS crypto bits from OpenLDAP

Hi Ludwig, We have yet to even alpha 2.5, and then there will be betas and potential RCs. I'd say we're overall at least a year out from an official 2.5 release. --Quanah --On Friday, January 15, 2016 3:02 PM +0100 Ludwig Krispenz <lkrispen(a)redhat.com> wrote: > Hi Quannah, > > not an objection to dropping it, but a question about timing. > We are using the openldap client library in 389-ds and rely on the fact > that they are linked to moznss.

Slapd startup behavior when unable to bind to an interface
by Quanah Gibson-Mount 11 Jan '16

11 Jan '16

Currently, slapd will start up even if it can't bind to an interface, if more than one potential interface is given where the bind is successful. This was, as best as Howard can recall, done because of ipv4/ipv6 issues on some systems. However, it seems to me that it should at least be possible to specify to slapd that you do not want it to start up unless binding to all interfaces is successful. This is fairly trivial to reproduce. As a non-privileged user, simply do: -h "ldap:// ldapi://slapd.sock" It will fail to bind to 389, but bind to the LDAPI socket anyway, and continue the startup process. This gives a false result that slapd started successfully, although clearly external clients will be unable to talk to it. --Quanah -- Quanah Gibson-Mount Platform Architect Zimbra, Inc. -------------------- Zimbra :: the leader in open source messaging and collaboration

Dropping the MozNSS crypto bits from OpenLDAP
by Quanah Gibson-Mount 11 Jan '16

11 Jan '16

Hi Jan, Now that the Crypto Consolidation project has been dropped by Fedora (<https://fedoraproject.org/wiki/FedoraCryptoConsolidation>), is there any objection to OpenLDAP dropping the MozNSS work going forward (OpenLDAP 2.5+)? We already have noted we don't support people using it, due to the security problems it creates, etc. Thanks, Quanah -- Quanah Gibson-Mount Platform Architect Zimbra, Inc. -------------------- Zimbra :: the leader in open source messaging and collaboration

Do env_sync() and commit() survive the test program from ITS#7886? It creates a datafile which ends before mm_last_pg+1.
