Some of the test cases reference to binlog position and these position numbers are written into result explicitly. It is difficult to maintain if log event format changes. There are a couple of cases explicit position number appears, we handle them in different ways A. 'CHANGE MASTER ...' with MASTER_LOG_POS or/and RELAY_LOG_POS options Use --replace_result to mask them. B. 'SHOW BINLOG EVENT ...' Replaced by show_binlog_events.inc or wait_for_binlog_event.inc. show_binlog_events.inc file's function is enhanced by given $binlog_file and $binlog_limit. C. 'SHOW SLAVE STATUS', 'show_slave_status.inc' and 'show_slave_status2.inc' For the test cases just care a few items in the result of 'SHOW SLAVE STATUS', only the items related to each test case are showed. 'show_slave_status.inc' is rebuild, only the given items in $status_items will be showed. 'check_slave_is_running.inc' and 'check_slave_no_error.inc' and 'check_slave_param.inc' are auxiliary files helping to show running status and error information easily.

# ==== Purpose ====
|
|
#
|
|
# Waits until a variable from SHOW STATUS has returned a specified
|
|
# value, or until a timeout is reached.
|
|
#
|
|
# ==== Usage ====
|
|
#
|
|
# let $status_var= Threads_connected;
|
|
# let $status_var_value= 1;
|
|
# --source include/wait_for_status_var.inc
|
|
#
|
|
# Parameters:
|
|
#
|
|
# $status_var, $status_var_value
|
|
# This macro will wait until the variable of SHOW STATUS
|
|
# named $status_var gets the value $status_var_value. See
|
|
# the example above.
|
|
#
|
|
# $status_type= GLOBAL|SESSION
|
|
# To specify the type (attribute) of status variable and
|
|
# run either SHOW GLOBAL STATUS or SHOW SESSION STATUS.
|
|
#
|
|
# $status_var_comparsion
|
|
# By default, this file waits until $status_var becomes equal to
|
|
# $status_var_value. If you want to wait until $status_var
|
|
# becomes *unequal* to $status_var_value, set this parameter to the
|
|
# string '!=', like this:
|
|
# let $status_var_comparsion= !=;
|
|
#
|
|
# $status_timeout
|
|
# The default timeout is 1 minute. You can change the timeout by
|
|
# setting $status_timeout. The unit is tenths of seconds.
|
|
#
