# Bug#24609402 MYSQLBINLOG --RAW DOES NOT GET ALL LATEST EVENTS
#
# Problem: When mysqlbinlog is used with --raw option, output file
#          is not getting flushed till the process is completed.
#          With --stop-never option (mysqlbinlog process never completes),
#          output file will never contain any event.
#
# Steps to reproduce:
#          1) Execute some dummy statements(a create and an insert).
#          2) Execute MYSQL_BINLOG with --stop-never and --raw option
#             and backup the binlog content.
#          3) Wait till server dump thread transfers all the data.
#          4) Copy binary log file that is downloaded till now before
#             stopping dump thread that is serving mysqlbinlog
#             --stop-never process.
#          5) kill the dump thread (serving the mysqlbinlog process).
#          6) Clean up the data on the server (a drop and a reset).
#          7) Apply binlog content (binlog from Step-2).
#          8) Check that table and the data in it exists (data from step-1).
#          9) Cleanup the server.
