ITS#6152 pcache enhancements
by Howard Chu 19 Aug '09

19 Aug '09

Just starting to look at implementing Time-To-Refresh, and wondering how it impacts other parameters. proxysavequeries allows queries to be saved and reloaded across restarts. Currently it will only reload non-expired queries. The implication of setting the offline mode is that expired entries may remain in the cache. Should they in fact be reloadable too? The proxytemplate directive has gotten a bit cumbersome, with optional negative TTL and sizelimit TTL added on. This would be the natural place to add the TTR config as well. Should there be independent TTR for negative and sizelimit too? (And it seems we should move from positional arguments to named arguments here...) Given the existence of a TTR feature, I'm less concerned about the proxysavequeries behavior. One should simply set a long TTL and set TTR as needed to keep the cache fresh. As a side point, I'd prefer more consistency in the config keyword names, we should have used "pcache" as the prefix for all the keywords... pcache <database> ... pcacheattrset <index> ... pcachemaxqueries <queries> pcachevalidate <bool> pcachepersist <bool> pcacheset template=<string> attrset=<index> ttl=<secs> [negttl=<secs>] ... pcacheposition (head|tail) -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

Re: HAVE_GMTIME_R?
by masarati＠aero.polimi.it 18 Aug '09

As far as I can tell (I cannot tell), the only issue should be with the WIN32 version of lutil_gettime(); the modifications I'm finalizing get rid of all mutexes except for directly 'round gmtime(3), but I don't know whether the WIN32 function GetSystemTime( &st ); is reentrant or not. I bet it is, since it works on a buffer passed by the caller. p.

Why not just the counts? Also, if there are thousands of cached queries, this could get to be an expensive lookup. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

Howard, I have another round of monitor-related mods to pcache. I could successfully merge your mods with mine. Do you mind if I commit, or do you have more to sync? p.

At the moment the idea for implementing refresh is to refactor syncrepl_entry() so that we can reuse the bulk of it. (Mainly the code that generates an appropriate Modify request based on the difference between the local entry and the remote entry.) Detecting renames will be trickier since the cache typically won't have any entryUUIDs. I think we'll simply have to treat it as a Delete / Add... -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

FAQ and ancient entries
by Quanah Gibson-Mount 15 Aug '09

15 Aug '09

In looking at our FAQ, many entries detail ancient (2.1 and earlier) information that is completely obsolete. It would be nice to be able to archive off the cruft so that the site is actually of more use. Thoughts on how best to achieve this? Some examples: SLAPD (with LDBM database) prerequisites include suitable database support. One of following packages can fulfill the prerequisite. Berkeley Database from Sleepycat (http://www.sleepycat.com/) GNU Database Manager (GDBM) from FSF (http://www.gnu.org/) For OpenLDAP 2.1 (or later), Berkeley DB 4.1 is recommended. SLURPD prerequisites include: Thread support (Posix Threads and others) SSL/TLS prerequisites: OpenSSL 0.9.6 from http://www.openssl.org The OpenSSL library usually needs to be patched before it will work correctly. See this FAQ article for details: http://www.openldap.org/faq/index.cgi?file=185 (Note about OpenSSL and crypt()) (Answer) How do I select a suitable LDBM backend? (Answer) How do I force LDBM to use of BerkeleyDB? (Answer) How do I force LDBM to use of GDBM? (Answer) Can LDBM use NDBM? etc. --Quanah -- Quanah Gibson-Mount Principal Software Engineer Zimbra, Inc -------------------- Zimbra :: the leader in open source messaging and collaboration
