From 2b9e5ac193ea91817ff17851a4a16a42a5b87fdb Mon Sep 17 00:00:00 2001 From: Rainer Gerhards Date: Mon, 6 Jun 2011 16:41:55 +0200 Subject: added a first implementation of a DNS name cache this still has a couple of weaknesses, like no size limit, no expiration of entries, suboptimal algorithms -- but it should perform better than what we had previously. Implementation will be improved based on feedback during the next couple of releases --- runtime/dnscache.h | 31 +++++++++++++++++++++++++++++++ 1 file changed, 31 insertions(+) create mode 100644 runtime/dnscache.h (limited to 'runtime/dnscache.h') diff --git a/runtime/dnscache.h b/runtime/dnscache.h new file mode 100644 index 00000000..9eee07ba --- /dev/null +++ b/runtime/dnscache.h @@ -0,0 +1,31 @@ +/* Definitions for dnscache module. + * + * Copyright 2011 by Rainer Gerhards and Adiscon GmbH. + * + * This file is part of the rsyslog runtime library. + * + * The rsyslog runtime library is free software: you can redistribute it and/or modify + * it under the terms of the GNU Lesser General Public License as published by + * the Free Software Foundation, either version 3 of the License, or + * (at your option) any later version. + * + * The rsyslog runtime library 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.
