# ==== Purpose ==== # # Assert that the binary log contains a specific sequence of logical # timestamps. # # ==== Usage ==== # # --let $binlog_file= FILENAME # [--let $binlog_position= OFFSET] # --let $logical_timestamps= LC1 SN1[;LC2 SN2[;LC3 SN3...]] # [--let $save_binlog_position= 1] # [--let $dont_print_logical_timestamps= 1] # --source include/assert_logical_timestamps.inc # # Parameters: # # $binlog_file # The binary log to look in. # # $binlog_position # By default, this script starts reading from the beginning of the # binary log. Set this to start reading from some specific offset. # # $logical_timestamps # This is a semicolon-separated list of pairs of logical # timestamps. Each pair consists of 'last_committed' as an # integer, followed by space, followed by 'sequence_number' as an # integer. Note that this is whitespace-sensitive so there should # not be any other space characters than those separating # last_committed from sequence_number. # # $save_binlog_position # If this flag is set, the script will source # include/save_binlog_position.inc after it has finished the # assert, making the next invocation automatically continue where # this invocation ended. This is convenient if the script is to # be called multiple times in a sequence. # # $dont_print_logical_timestamps # By default, $logical_timestamps is printed to the result log. If # this flag is set, that is suppressed. --let $include_filename= include/assert_logical_timestamps.inc [$logical_timestamps] if ($dont_print_logical_timestamps) { --let $include_filename= include/assert_logical_timestamps.inc } --source include/begin_include_file.inc --let $assert_file= `SELECT CONCAT('$MYSQLTEST_VARDIR/tmp/_alt_', UUID())` # Run mysqlbinlog. --let $_alt_offset= if ($binlog_position) { --let $_alt_offset= --start-position=$binlog_position } --let $_alt_datadir= `SELECT @@datadir` --exec $MYSQL_BINLOG --force-if-open $_alt_offset $_alt_datadir/$binlog_file > $assert_file # Check for match. --let $assert_select= last_committed=.*sequence_number=.* --let $assert_match= `SELECT CONCAT('last_committed=', REPLACE(REPLACE('$logical_timestamps', ';', '.*\n[^\n]*last_committed='), ' ', '\tsequence_number='))` --let $assert_text= assert_logical_timestamps: $logical_timestamps --let $extra_debug_info= Expected logical timestamps: $logical_timestamps --source include/assert_grep.inc --remove_file $assert_file if ($save_binlog_position) { --source include/save_binlog_position.inc } --let $include_filename= include/assert_logical_timestamps.inc [$logical_timestamps] --source include/end_include_file.inc
