# ==== 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.
