has (in mysql-test-run) a slave-net-timeout=10. So the 'sleep 1' below was converted in 'sleep 10', so slave thought that connection was down, so reconnected, so got an additional (fake) Rotate event, which shifted the positions displayed by SHOW SLAVE STATUS.

# 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
