# ==== Purpose ====
#
# The purpose of this script is to test that the binary log thread
# does not exit in case events are written after some "idle" time,
# after which the source sends heartbeat messages to the replica
#
# ==== Requirements ====
#
# R1. Dump thread with heartbeat option enabled should disconnect
# only if an error occurs (send/flush).
#
# ==== Implementation ====
#
# 1. Setup a simple replication topology : source -> replica
# 2. Setup heartbeat period to 1 ms
# 3. Execute `mysqlslap` in a loop.
# Let the source send heartbeat messages between iterations.
# 4. Sync the replica.
# 5. Verify that dump thread was not restarted between mysqlslap
# iterations. Dump thread should exit only if a network is
# unstable, e.g. there was an error on "send" or "flush".
# 6. Cleanup
#
# ==== References ====
#
# BUG#34860923 Timeout on cv in waiting with heartbeat cause dump thread to stop
