From a599edf04cbdeef9014923ba0d3713b8ff84f266 Mon Sep 17 00:00:00 2001 From: Andrew Tridgell Date: Wed, 12 Oct 2005 06:10:23 +0000 Subject: r10913: This patch isn't as big as it looks ... most of the changes are fixes to make all the ldb code compile without warnings on gcc4. Unfortunately That required a lot of casts :-( I have also added the start of an 'operational' module, which will replace the timestamp module, plus add support for some other operational attributes In ldb_msg_*() I added some new utility functions to make the operational module sane, and remove the 'ldb' argument from the ldb_msg_add_*() functions. That argument was only needed back in the early days of ldb when we didn't use the hierarchical talloc and thus needed a place to get the allocation function from. Now its just a pain to pass around everywhere. Also added a ldb_debug_set() function that calls ldb_debug() plus sets the result using ldb_set_errstring(). That saves on some awkward coding in a few places.
