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.

New logging system ideas
by Howard Chu 18 Jul '21

18 Jul '21

Just some initial thoughts on what a new logging daemon should do for us: The primary goal - we want to use a binary message format with as few format conversions as possible between log sender and log processor. I'm thinking that we use message catalogs; we will need a tool to preprocess every logging invocation in the source tree and replace them with a integer messageID. So at runtime only the messageID and the message parameters need to be sent, not any plaintext. The message catalog will be compiled into the binary. When it performs its "openlog" to talk to the logging server, it will send the UUID of its catalog. If the logging server doesn't know this UUID, it will transmit the message catalog to the logging server, before doing anything else. (It may make more sense just to use a SHA hash here instead of a UUID.) This way the logging server will work with any version of the binaries, and we don't need to do special coordination to update message catalogs between revisions. The logging server will just know that a specific catalog is to be used with a particular logging session. The message protocol will be length-prefixed. We may even just use DER, since that would allow us to encode arrays of parameters, and other such stuff. The logging server will write the log messages to disk/network verbatim, doing no parsing at all. It may prefix the records with a log session ID, so that a postprocessor can lookup the catalog that belongs to the session, for dumping out as text. The logging server can store its received catalogs in an LMDB database. The postprocessor can then lookup individual messageIDs in this database, interpolate the parameters, and dump out in text. ... that's what I have so far. It's a bit worrisome because of the additional moving parts: message catalog creator, log server, log postprocessor. There's definitely more complexity here, but most of it is moved out of the runtime hot path, which is the main goal.

HI! With RE25 branch make depend fails on my system (see below). Find attached my build script which works just fine for RE24. Any changes needed for RE25? Ciao, Michael. cd back-shell && make -w depend make[3]: Entering directory '/home/michael/src/openldap-git/re25/openldap/servers/slapd/back-shell' make[3]: *** No rule to make target 'Makefile.in', needed by 'Makefile'.

ppolicy control exposure in RE24?
by Quanah Gibson-Mount 13 Jul '20

13 Jul '20

Currently the ppolicy overlay does not expose the related control in the supportedControl attribute of the rootDSE. This is due to the general policy that controls for items that are not part of a finalized specification are not published. However, at this point, ppolicy while not finalized, is long established. For 2.5, we will be exposing the control, but I think it could be useful to do this for 2.4.51+ as well. Does anyone have any objections to this change being backported to RE24? <https://bugs.openldap.org/show_bug.cgi?id=9285> Thanks, Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>
