From 0dd6a759ed41960500e0869bfe96d93b2d11f50a Mon Sep 17 00:00:00 2001 From: Kamen Mazdrashki Date: Fri, 25 Jun 2010 04:30:21 +0300 Subject: s4/drs-test: Tests Deleted objects replication Tests how deleted objects are replicated between two DCs. Currently the test exploits following vulnerabilities: - DsReplicaSync is not correctly implemented - a 'deleted object' is restored (kind of) in case DC1 replicates from DC2 before the 'deleted object' is replicated --- source4/torture/drs/python/delete_object.py | 222 ++++++++++++++++++++++++++++ 1 file changed, 222 insertions(+) create mode 100755 source4/torture/drs/python/delete_object.py (limited to 'source4/torture') diff --git a/source4/torture/drs/python/delete_object.py b/source4/torture/drs/python/delete_object.py new file mode 100755 index 0000000000..6b75b80346 --- /dev/null +++ b/source4/torture/drs/python/delete_object.py @@ -0,0 +1,222 @@ +#!/usr/bin/env python +# -*- coding: utf-8 -*- +# +# Unix SMB/CIFS implementation. +# Copyright (C) Kamen Mazdrashki 2010 +# +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 3 of the License, or +# (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
