# ==== Purpose ====
#
# Test verifies that, in parallel replication, transaction failure notification
# is propagated to all the workers. Workers should abort the execution of
# transaction event groups, whose event positions are higher than the failing
# transaction group.
#
# ==== Implementation ====
#
# Steps:
# 0 - Create a table t1 on master which has a primary key. Enable parallel
# replication on slave with slave_parallel_mode='optimistic' and
# slave_parallel_threads=3.
# 1 - On slave start a transaction and execute a local INSERT statement
# which will insert value 32. This is done to block the INSERT coming
# from master.
# 2 - On master execute an INSERT statement with value 32, so that it is
# blocked on slave.
# 3 - On slave enable a debug sync point such that it holds the worker thread
# execution as soon as work is scheduled to it.
# 4 - INSERT value 33 on master. It will be held on slave by other worker
# thread due to debug simulation.
# 5 - INSERT value 34 on master.
# 6 - On slave, enusre that INSERT 34 has reached a state where it waits for
# its prior transactions to commit.
# 7 - Commit the local INSERT 32 on slave server so that first worker will
# error out.
# 8 - Now send a continue signal to second worker processing 33. It should
# wakeup and propagate the error to INSERT 34.
# 9 - Upon slave stop due to error, check that no rows are found after the
# failed INSERT 32.
#
# ==== References ====
#
# MDEV-20645: Replication consistency is broken as workers miss the error
# notification from an earlier failed group.
