From 7b368f006eea17a8b08cac9e6e79e58977edf864 Mon Sep 17 00:00:00 2001 From: Quincey Koziol Date: Wed, 6 Dec 2006 17:19:52 -0500 Subject: [svn-r13028] Description: Add first pass of "dense" attribute storage to objects. Lots of parts of this are stubbed out, but all the tests are passing and I'll work on the corner cases soon. Eliminated several unused parameters from object header message callback routines. Other, miscellaneous code cleanups, etc. (and probably some things I've forgotten about... :-) Tested on: FreeBSD/32 4.11 (sleipnir) Linux/32 2.4 (heping) AIX/32 5.?
