# ==== Purpose ====
|
|
#
|
|
# Test verifies that when RESET MASTER TO # command is supplied with binlog
|
|
# extension number greater than 2147483647 the command should report
|
|
# appropriate error and binary log should be disabled. It should not result in
|
|
# a crash.
|
|
#
|
|
# ==== Implementation ====
|
|
#
|
|
# Steps:
|
|
# 0 - Verify case with max binary log extension. Max value is '2147483647'
|
|
# 1 - Confirm that SHOW BINARY LOGS displays a binary log with '2147483647'
|
|
# 2 - Verify that events are successfully written into max extension file.
|
|
# 3 - Try to create a binary log with extension greater than max allowed
|
|
# value '2147483648', verify ER_NO_UNIQUE_LOGFILE error is reported.
|
|
# 4 - Execute CREATE DATABASE db2 statement and verify server doesn't crash.
|
|
# 5 - Execute SHOW BINARY LOG command and verify that it reports
|
|
# ER_NO_BINARY_LOGGING error.
|
|
# 6 - Restart the server and verify that database 'db2' exists and it is not
|
|
# present in the binary log.
|
|
