# Test is run with max_binlog_size=2048 to force automatic rotation of the
# binary log
# Tests done:
# - Check that slaves reports correct failures if master.info has strange
#   modes/information
# - Automatic binary log rotation
# - Ensure that temporary tables works over flush logs and binary log
#   changes
# - Test creating a duplicate key error and recover from it
