From b1a252a64d39d17618d2d00ac341684b6f290ef6 Mon Sep 17 00:00:00 2001 From: Max Kellermann Date: Sun, 5 Oct 2014 07:41:50 +0200 Subject: lib/nfs/Base: kludge to reduce number of NFS mounts Creating a NfsStorage sets its own export_name as the "base". Now NfsFileReader can use this information to derive the export_name to be mounted, instead of guessing. This solves the "too many connection" problem on the NFS server while updating the database. --- src/lib/nfs/Base.hxx | 46 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 src/lib/nfs/Base.hxx (limited to 'src/lib/nfs/Base.hxx') diff --git a/src/lib/nfs/Base.hxx b/src/lib/nfs/Base.hxx new file mode 100644 index 000000000..3a92a86d3 --- /dev/null +++ b/src/lib/nfs/Base.hxx @@ -0,0 +1,46 @@ +/* + * Copyright (C) 2003-2014 The Music Player Daemon Project + * http://www.musicpd.org + * + * 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 2 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.
