# ==== Purpose ====
|
|
#
|
|
# Crash all servers that were configured with rpl_init.inc/master-slave.inc.
|
|
#
|
|
# This should be used only for debugging test cases, when you need the
|
|
# core file. To stop a server as part of a test scenario, use one of
|
|
# rpl_stop_server.inc, rpl_restart_server.inc, kill_mysqld.inc,
|
|
# restart_mysqld.inc, etc.
|
|
#
|
|
# ==== Implementation ====
|
|
#
|
|
# This relies on a debug symbol that causes the server to call
|
|
# DBUG_ASSERT(0). So it only works on debug-compiled servers.
|
|
#
|
|
# ==== Usage ====
|
|
#
|
|
# [in main test: source include/have_dbug.inc]
|
|
# [--let $connection_suffix = _1]
|
|
# --source include/dbug_crash_all.inc
|
|
#
|
|
# Parameters:
|
|
# $connection_suffix
|
|
# By default, uses connections server_1, server_2, etc.
|
|
# Set this variable to use server_1$connection_suffix,
|
|
# server_2$connection_suffix, etc.
|
|
|
|
|
|
# Tell all servers to crash
|
|
--let $_rpl_server = $rpl_server_count
|
|
while ($_rpl_server) {
|
|
--connection server_$_rpl_server$server_suffix
|
|
--echo # Crashing server_$_rpl_server$server_suffix
|
|
send SET SESSION debug = 'd,crash_now';
|
|
--dec $_rpl_server
|
|
}
|
|
|
|
# Wait until connection drops
|
|
--let $_rpl_server = $rpl_server_count
|
|
while ($_rpl_server) {
|
|
--connection server_$_rpl_server$server_suffix
|
|
--error 0,1040,1053,2002,2003,2006,2013,2016,2017
|
|
--reap
|
|
--dec $_rpl_server
|
|
}
