From 14de5f76687ec5b45e53ca1fa22885429ed3b875 Mon Sep 17 00:00:00 2001 From: Siri Hansen Date: Fri, 4 Apr 2014 16:55:44 +0200 Subject: Don't allow slave nodes to survive their test case The slave node from release_handler_SUITE:upgrade_supervisor_fail sometimes survives its test case. Or rather, it is unexpectedly restarted. Every now and then, on a slow machine, this confuses the next test case since test_server:start_node might return the old node name instead of the new. This has been corrected by using {error_action,reboot} in release_handler_SUITE:upgrade_supervisor_fail - to make sure the slave node is really terminated on rollback. --- lib/sasl/test/release_handler_SUITE.erl | 35 +++++++++++++++++++++++++++------ 1 file changed, 29 insertions(+), 6 deletions(-) (limited to 'lib/sasl') diff --git a/lib/sasl/test/release_handler_SUITE.erl b/lib/sasl/test/release_handler_SUITE.erl index 1d8bf45289..8a635796b7 100644 --- a/lib/sasl/test/release_handler_SUITE.erl +++ b/lib/sasl/test/release_handler_SUITE.erl @@ -1410,18 +1410,41 @@ upgrade_supervisor_fail(Conf) when is_list(Conf) -> {error,{code_change_failed,_Pid,a_sup,_Vsn, {error,{invalid_shutdown,brutal_kil}}}} = - rpc:call(Node, release_handler, install_release, [RelVsn2]), - - %% Check that the upgrade is terminated - normally this would mean - %% rollback, but since this testcase is very simplified the node - %% is not started with heart supervision and will therefore not be - %% restarted.
