# Bug#26027024 SLAVE_COMPRESSED_PROTOCOL DOESN'T WORK WITH SEMI-SYNC
# REPLICATION IN MYSQL-5.7
#
# Steps to reproduce:
# 1) Set slave_compressed_protocol ON on Slave.
# 2) Do some sample work on Master
# 3) After the work is synced on Slave, check that there is no error
# (Read semi-sync reply magic number error) on Slave.
# 4) Cleanup
################################################################################
# Test is independent of Binlog format. One of the three formats is enough
# for testing. Choosing 'Row' format.
