From d82cbb3a81f116cd22e9895ecac36ac3d7b38929 Mon Sep 17 00:00:00 2001 From: Martin Sustrik Date: Thu, 5 Apr 2012 07:32:58 +0200 Subject: XS_PLUGIN and XS_FILTER implementation This patch introduces following features: - XS_PLUGIN context option to add plugins to libxs - XS_FILTER option to switch between different filter types - Automatic loading of plug-ins is *not* implemented. From the implementation point of view: - standard prefix filter is implemented as a pluggable filter - trie_t and mtrie_t are joined into a single class - the code for 0MQ/3.1 compatibility is left in in the form of comments - new test for testing re-subscriptions is added Signed-off-by: Martin Sustrik --- tests/resubscribe.cpp | 103 ++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 103 insertions(+) create mode 100644 tests/resubscribe.cpp (limited to 'tests/resubscribe.cpp') diff --git a/tests/resubscribe.cpp b/tests/resubscribe.cpp new file mode 100644 index 0000000..1924434 --- /dev/null +++ b/tests/resubscribe.cpp @@ -0,0 +1,103 @@ +/* + Copyright (c) 2012 250bpm s.r.o. + Copyright (c) 2012 Other contributors as noted in the AUTHORS file + + This file is part of Crossroads I/O project. + + Crossroads I/O 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. + + Crossroads 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.
