From 334e0ea11f8740a1102ab8411a959cf8b364eb4d Mon Sep 17 00:00:00 2001 From: Hans Bolinder Date: Wed, 25 Aug 2010 13:28:38 +0200 Subject: Fix a bug that could cause the net_kernel process to crash. A bug introduced in kernel-2.13.5.3 has been fixed. If running net_kernel:set_net_ticktime/1 twice within the TransitionPerod the second call caused the net_kernel process to crash with a badmatch. --- lib/kernel/test/erl_distribution_SUITE.erl | 2 ++ 1 file changed, 2 insertions(+) (limited to 'lib/kernel/test/erl_distribution_SUITE.erl') diff --git a/lib/kernel/test/erl_distribution_SUITE.erl b/lib/kernel/test/erl_distribution_SUITE.erl index d15f6aa0d5..21a96f804a 100644 --- a/lib/kernel/test/erl_distribution_SUITE.erl +++ b/lib/kernel/test/erl_distribution_SUITE.erl @@ -273,6 +273,7 @@ tick_change(Config) when is_list(Config) -> ?line PaDir = filename:dirname(code:which(?MODULE)), ?line [BN, CN] = get_nodenames(2, tick_change), ?line DefaultTT = net_kernel:get_net_ticktime(), + ?line unchanged = net_kernel:set_net_ticktime(DefaultTT, 60), ?line case DefaultTT of I when is_integer(I) -> ?line ok; _ -> ?line ?t:fail(DefaultTT) @@ -377,6 +378,7 @@ run_tick_change_test(B, C, PrevTT, TT, PaDir) -> end, ?line change_initiated = net_kernel:set_net_ticktime(TT,20), + ?line {ongoing_change_to,_} = net_kernel:set_net_ticktime(TT,20), ?line sleep(3), ?line change_initiated = rpc:call(B,net_kernel,set_net_ticktime,[TT,15]), ?line sleep(7), -- cgit v1.2.3
