Other? Sounds very interesting; discussions of this nature (modifications to OpenLDAP code) are most appropriate for the -devel list.

I have been testing pretty consistently on Solaris this year, most recent on HEAD versus RELEASE. thats how I noticed the ITS 6621 issue. I may be able to do some specific testing on specific hardware platforms, depending on what is desired, and what I can get access to. I do regulary test on both x86 and sparc platforms. Also, I now have Oracle legal permission to pass OpenLDAP enhancements and fixes upstream. I am almost ready to submit a proposed patch to libldap to deliver a revised version of draft-zeilenga-ldap-c-api-concurrency-00.txt functionality for OpenLDAP libldap. My proposed patch so far implements the ldap_dup and ldap_destroy portions of the specification, but I have not yet implemented the LDAP_OPT_SESSION_REFCNT or added any LDAP_API_FEATURE* style macros. I would like some guidance if/what macros in ldap.h are desired. I am working on the assumption that some public discussion and peer review will be expected before any patch submission would be accepted. Should I start with a discussion on openldap-technical first? Other? Doug. On 08/12/10 06:21 PM, hyc(a)symas.com wrote: > masarati(a)aero.polimi.it wrote: >> Blind-fixed in HEAD.

Too bad, a Niagara might actually show more than a 1% gain from the multi-listener patch. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

A (blind) fix is in HEAD; you need to pull modifications related to this ITS and to ITS#6622. Please test and report. p.
