mariadb/mysql-test/include/kill_binlog_dump_threads.inc

# ==== Purpose ====
#
# Terminate all binlog dump threads on a master.
#
# This is sometimes useful, as normally such dump threads can hang
# around for some time before they notice that the slave has disconnected.
#
# Note that if there are active slave connections, they might try to
# reconnect as their dump threads are killed, which may not lead to the
# desired results.
#
#
# ==== Usage ====
#
# [--let $kill_timeout= NUMBER]
# --source include/stop_slavekill_binlog_dump_threads.inc
#
# Parameters:
#   $kill_timeout
#     Maximum number of seconds to wait for dump threads to disappear.
