That would cause +# maintenance problems, because (1) it is hard for a human to +# understand what property is being tested; (2) the output of many of +# the fields is non-deterministic (e.g., Slave_IO_State) or changes +# frequently (e.g., binlog positions). +# +# Instead, what you want most of the time is to source one of the +# following scripts: +# +# include/check_slave_no_error.inc +# Assert that Slave_SQL_Errno = Slave_IO_Errno = 0. +# +# include/check_slave_is_running.inc +# Assert that Slave_IO_Running = Slave_SQL_Running = 'Yes'. +# +# include/wait_for_slave_sql_error.inc +# Wait for the SQL thread to get a given error (and assert that +# it has this error). +# +# include/wait_for_slave_io_error.inc +# Wait for the IO thread to get a given error (and assert that +# it has this error). +# +# include/wait_for_slave_sql_to_stop.inc +# include/wait_for_slave_io_to_stop.inc +# include/wait_for_slave_to_stop.inc +# Wait for the SQL thread, the IO thread, or both to stop (and +# assert they stop). +# +# When none of the above applies, you may use this script instead. +# However, take care so that the test never contains explicit binlog +# coordinates.
