# ==== Purpose ====
|
|
#
|
|
# Test verifies that auto purging mechanism of relay logs works fine when the
|
|
# file extension grows beyond 999999.
|
|
#
|
|
# ==== Implementation ====
|
|
#
|
|
# Steps:
|
|
# 0 - In master-slave setup clear all the relay logs on the slave server.
|
|
# 1 - Start the slave so that new relay logs starting from
|
|
# 'slave-relay-bin.000001' are created.
|
|
# 2 - Get the active relay-log file name by using SHOW SLAVE STATUS.
|
|
# Shutdown the slave server.
|
|
# 3 - Rename active relay log to '999997' in both 'relay-log.info' and
|
|
# 'slave-relay-bin.index' files.
|
|
# 4 - Restart the slave server by configuring 'slave_parallel_threads=1'
|
|
# and 'max_relay_log_size=100K'.
|
|
# 5 - Generate load on master such that few relay logs are generated on
|
|
# slave. The relay log sequence number will change to 7 digits.
|
|
# 6 - Sync slave with master to ensure that relay logs are applied on
|
|
# slave. They should have been automatically purged.
|
|
# 7 - Assert that there is no 'slave-relay-bin.999999' file in
|
|
# 'relay-log.info'.
