# ==== Purpose ==== # # Assert that exactly one GTID (or a specified number) was added to # @@GLOBAL.GTID_EXECUTED since last call to gtid_step_reset.inc or # gtid_step_assert.inc # # ==== Usage ==== # # [--let $gtid_step_count= N] # [--let $gtid_step_only_count= [0|1]] # [--let $gtid_step_uuid= UUID] # --source include/gtid_step_assert.inc # # Parameters: # $gtid_step_count # Assert that N GTIDs were added to @@GLOBAL.GTID_EXECUTED. If # this is not given, the default value is 1. # # $gtid_step_only_count # By default, this script checks the numeric component of the # GTIDs added to @@GLOBAL.GTID_EXECUTED to see that the correct # number was generated. If this parameter is nonzero, it only # counts the number of added GTIDs to see that it is equal to # $gtid_step_count, without caring that they were generated in # order (or generated on this server). # # $gtid_step_uuid # By default, when $gtid_step_count is not set, asserts that the # uuid component of all GTIDs added to @@GLOBAL.GTID_EXECUTED is # equal to @@GLOBAL.SERVER_UUID. If this parameter is given, uses # that UUID instead. # # ==== Example ==== # # # (1) Remember the current position. # --source include/gtid_step_reset.inc # CREATE TABLE t1 (a INT); # # (2) Assert that exactly one GTID was generated since (1). # --source include/gtid_step_assert.inc # INSERT INTO t1 VALUES (1); # INSERT INTO t1 VALUES (2); # # (3) Assert that exactly 2 GTIDs were generated since (2). # --let $gtid_step_count= 2 # --source include/gtid_step_assert.inc # # (4) Assert that no GTID was generated since (3). # --let $gtid_step_count= 0 # --source include/gtid_step_assert.inc if ($uuidf == '') { --die You must source gtid_utils.inc before using gtid_step_assert.inc } --let $_gtid_step_count= 1 if ($gtid_step_count != '') { --let $_gtid_step_count= $gtid_step_count } --let $_gtid_step_only_count= 0 if ($gtid_step_only_count != '') { --let $_gtid_step_only_count= $gtid_step_only_count } --let $include_filename= gtid_step_assert.inc [count=$_gtid_step_count, only_count=$_gtid_step_only_count] --source include/begin_include_file.inc --let $_gtid_step_uuid= $gtid_step_uuid if ($_gtid_step_uuid == '') { --let $_gtid_step_uuid= `SELECT @@GLOBAL.SERVER_UUID` } --let $_gsa_extra_debug_eval_old= $extra_debug_eval --let $extra_debug_eval= @@GLOBAL.GTID_EXECUTED, GTID_NEXT_GENERATED_SET("$gtid_step_last", "$_gtid_step_uuid", $_gtid_step_count), GTID_SUBTRACT(@@GLOBAL.GTID_EXECUTED, "$gtid_step_last") if ($_gtid_step_only_count) { --let $assert_text= Exactly $_gtid_step_count GTIDs should have been committed since last invocation --let $assert_cond= GTID_COUNT(GTID_SUBTRACT(@@GLOBAL.GTID_EXECUTED, "$gtid_step_last")) = $_gtid_step_count --source include/assert.inc } if (!$_gtid_step_only_count) { --let $assert_text= Exactly $_gtid_step_count GTIDs should have been generated since last invocation --let $assert_cond= GTID_NEXT_GENERATED_SET("$gtid_step_last", "$_gtid_step_uuid", $_gtid_step_count) = GTID_SUBTRACT(@@GLOBAL.GTID_EXECUTED, "$gtid_step_last") --source include/assert.inc } --let $extra_debug_eval= $_gsa_extra_debug_eval_old --source include/gtid_step_reset.inc --let $include_filename= gtid_step_assert.inc --source include/end_include_file.inc
