Instead of making the external module malloc its error message string, we should have passed in a struct berval with a buffer and length(buffer) already set. I'd like to change this for 2.5, it will also simplify ITS#6082. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

It's clear that what we really want is for pcache to behave the same in the cached vs uncached case, wrt other overlays/callbacks. So wherever pcache takes control in the call stack for the uncached case, it should do the same in the cached case. What's not clear is how to do that in general. When "response-callback head" has been configured, it should just execute and leave the callback stack intact when answering from cache. When "tail" (the default) is in effect then it probably should bypass the stack. The above commit just leaves the stack intact; I'll fix it up now to depend on the response-callback setting. > * To: OpenLDAP Commit <openldap-commit2devel(a)OpenLDAP.org> > * Subject: Re: commit: ldap/servers/slapd/overlays pcache.c > * From: Pierangelo Masarati <ando(a)sys-net.it> > * Date: Tue, 24 Aug 2004 10:40:00 +0200 > ando(a)OpenLDAP.org wrote: > > > Update of /repo/OpenLDAP/pkg/ldap/servers/slapd/overlays > > > Modified Files: > pcache.c 1.31 -> 1.32 > > > Log Message: > - proxy cache erroneously returns the filtering attributes > and the objectClass right after caching, even if not requested, > while subsequent searches are fine; > > > I think this is a bug; it was also reflected in the test data, which has been > fixed accordingly > > - the response callback needs be apended at the end of the > callback list, otherwise the resulting entries are cached > > > I ran into this issue while developing an overlay that dynamically builds > entries; the raw entry was being cached instead of the completed one, > because pcache adds its callback only when required, while that of my > overlay is stacked by the overlay infrastructure.

Re: held locks after exit
by Benoit Donnette 11 Jun '09

11 Jun '09

Well, you've highlighted 4 unreleased locks, a solution quite like using a sledgehammer to crack a nut but predictably efficient would be to backtrace() every lock and unlock so as to match them and to identify which locks haven't been released (but your traces show enough detail to help us focus the watch on specific db4 code). If this can help. > After an otherwise "clean" exit of test058, the smc/db directory showed > the following, despite the fact that there was no more 9196 pid on the > system.
