# Bug#24285104 RELAY LOG CORRUPTION NOT HANDLED CORRECTLY WITH MULTI-SOURCE
# REPLICATION
#
# Problem: Corruption of one channel's relay logs + server restart is
#          making few channels (good channels) to disappear.
#
# Steps to reproduce:
# -------------------
# In this test script, we will experiment with '4' servers.
# 1->4, 2->4, 3->4 is the MSR setup (server4 (the last server) is MSR slave).
# In this test script, there will be 3 channels created
#     > default channel (empty channel name) used for 1->4
#     > channel_1 not used in this test.
#     > channel_2 used for 2->4
#     > channel_3 used for 3->4
#
# Iterate through all the channels, corrupt one channel in each iteration.
# And execute some basic commands for testing purpose.
# First iteration: default channel corrupted (the first channel in the list)
# Second iteration: channel2 is corrupted (the middle channel in the list)
# Third iteration: channel3 is corrupted ( the last channel in the list).
# In this we can cover all the combinations of channel list with corrupted and
# good channels.
