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?

RE24 testing call #2 (2.4.45) LMDB RE0.9 testing call #2 (0.9.20)

For this testing call, we particularly need folks to test OpenLDAP with startTLS/LDAPS when compiled against OpenSSL (both pre 1.1 series and with the 1.1 series). This was reworked since the prior testing call, as the OpenSSL 1.1.0 work was not correct. There is currenly nothing in the test suite that covers encrypted connections (Although it's on my todo list). To build against OpenSSL 1.1 may also require cyrus-sasl HEAD out of the cyrus-sasl GIT repository, depending on your build options as the current cyrus-sasl release does not support the OpenSSL 1.1 series. It can be found at <https://github.com/cyrusimap/cyrus-sasl>. If you build with GSSAPI and use Heimdal, you will also need the Heimdal 7.1.0 or later release (as that is where OpenSSL 1.1 support was added). It can be obtained from <http://h5l.org/>. Also new with this release is the ability to run "make its" in the tests/ directory. This will run a specific set of tests around past bugs to ensure there are no regressions. While I've tested this with modular openldap builds, it has not been tested with the modules and backends built into slapd, so there could be some issues in that scenario.

Perhaps a failure if someone tries to set olcMirrorMode to TRUE when serverID is 0. That covers the MMR case, but it doesn't cover the non-MMR case where unique serverIDs are required with separate masters and glued databases. --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

Would it be possible to check serverID during slapd startup with MMR setup and fail to start with an error message in case serverID is 0? Ciao, Michael.
