# This test verifies that semi-sync setups configured to use SSL can kill
|
|
# the replication connection when the IO thread is stopped (e.g. from
|
|
# STOP SLAVE). The way it should happen, is that the IO thread creates a new
|
|
# connection to the primary which issues KILL on the connection id of the
|
|
# replication connection. MDEV-36663 reported an issue where this new
|
|
# kill-oriented connection could not connect to a primary when it requires
|
|
# connections to use SSL.
|
|
#
|
|
# This test sets up a semi-sync SSL master-slave topology, and stops the
|
|
# slave IO thread. It then validates that the connection was killed by using
|
|
# the wait_condition.inc utility to wait for the binlog dump thread to die,
|
|
# and also validates that the status variable Rpl_semi_sync_master_clients
|
|
# reports as 0.
