# ==== 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. # # $status_fail_query # This can be set to an SQL statement which will be executed if the # script fails. Useful for debugging. if (`SELECT STRCMP('$status_type', '') * STRCMP(UPPER('$status_type'), 'SESSION') * STRCMP(UPPER('$status_type'), 'GLOBAL')`) { --echo **** ERROR: Unknown type of variable status_type: allowed values are: SESSION or GLOBAL **** die; } let $_status_timeout_counter= $status_timeout; if (!$_status_timeout_counter) { let $_status_timeout_counter= 600; } let $_status_var_comparsion= $status_var_comparsion; if (!$_status_var_comparsion) { let $_status_var_comparsion= =; } # Get type of variable let $_is_number= 0; if (`SELECT '$status_var_value' REGEXP '^[\+\-]*[0-9]+(\.[0-9]+)*\$'`) { let $_is_number= 1; } let $_show_status_value= query_get_value("SHOW $status_type STATUS LIKE '$status_var'", Value, 1); # Set way of comparing let $_query= SELECT NOT('$_show_status_value' $_status_var_comparsion '$status_var_value'); if ($_is_number) { let $_query= SELECT NOT($_show_status_value $_status_var_comparsion $status_var_value); } while (`$_query`) { if (!$_status_timeout_counter) { if ($status_fail_query) { --echo # debug output: eval $status_fail_query; } --echo **** ERROR: failed while waiting for $status_type $status_var $_status_var_comparsion $status_var_value **** --echo Note: the following output may have changed since the failure was detected --echo **** Showing STATUS, PROCESSLIST **** eval SHOW $status_type STATUS LIKE '$status_var'; SHOW PROCESSLIST; die; } dec $_status_timeout_counter; sleep 0.1; let $_show_status_value= query_get_value("SHOW $status_type STATUS LIKE '$status_var'", Value, 1); let $_query= SELECT NOT('$_show_status_value' $_status_var_comparsion '$status_var_value'); if ($_is_number) { let $_query= SELECT NOT($_show_status_value $_status_var_comparsion $status_var_value); } }
