# Bug #21816399 5.6.24: LOST DATA DURING MASTER RESTART IF PARTIAL TRANSACT HAS
# BEEN DOWNLOADED
#
# Problem: If dump thread is killed (during shutdown/explicit kill) during
# dumping a non-active binary log, events in the binary log are not getting
# replicated.
# Steps to reproduce:
# 1) Create a binary log with some events
# 2) Rotate it to make it non-active log
# 3) While dump thread is sending data to slave, kill it.
# 4) Make sure that dump thread is killed
# 5) Start dump thread
# 6) See that there is no issue in replication
