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.

Fwd: LMDB and text encoding

(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.... I'm not sure if we can just copy-paste BDB's code. Probably not, that would lead to licensing issues, wouldn't it?

Any update on LMDB support for OpenBSD?

by Tinker

Hi Howard, Any plan on making LMDB work on OpenBSD? OpenBSD should deliver LMDB in the MDB_WRITEMAP mode. (http://lmdb.tech/doc/group__mdb.html) (At least some effort has been done e.g. https://gitlab.com/mdb/sqlightning/issues/6 ) Thanks, Tinker

When must slap_callback.sc_writewait be set?

by Hallvard Breien Furuseth

When is it safe to leave sc_writewait uninitialized? The field seems to have emerged in the middle of RE24, and I don't see any flags which say it should/should not be used. Since not setting it crashed back-relay in ITS#8428, does that mean everything which creates a slap_callback should set it? Seems unfortunate for third-party modules... Also, I think this should be documented. -- Hallvard
