(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?

commit "ITS#8226 limit size of read txns in searches" has a bug

by Леонид Юрьев

Hi, Howard. wwctx.txn may be uninitialized, see lines 712-720 of back-mdb/search.c http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=blob;f=servers/... And therefore mdb_rtxn_snap() may segfault when will called from line 1127. http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=blob;f=servers/... I think, one of the following should be: - wwctx should be initialize completely at 712; or - an additional condition should be checked at 1123-1125. Regards, Leonid.

Dynamic groups, autogroup

by Howard Chu

For the record - I've never liked the autogroup overlay. It's a fairly brute-force solution to what should be dynamic groups, making them into static ones. The limitation in dyngroup/dynlist about being unable to match member=foo filters is annoying, of course. But having worked thru a similar problem in the contrib/adremap overlay, the solution now is obvious - just use an additional search request, to find all of the dynamic groups in the scope (autogroup already does this once, at startup time) and then feed the filter attribute to each, one by one, doing the same evaluation that dyngroup's Compare handler already does. For sites with very large groups, dynamic groups are generally the right approach, for size/efficiency reasons. autogroup throws away any efficiency gains, but we can get them back. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/
