With MDEV-532, the binlog_checkpoint event is logged asynchronously from a binlog background thread. This causes some sporadic failures in some test cases whose output depends on order of events in binlog. Fix using an include file that waits until the binlog checkpoint event has been logged before proceeding with the test case.

|
# SUMMARY
|
|
#
|
|
# Wait until binlog checkpoint has been logged for current binlog file.
|
|
# This is useful to avoid races with output difference for binlog
|
|
# checkpoints, as these are logged asynchronously from the binlog
|
|
# background thread.
|
|
#
|
|
# USAGE:
|
|
#
|
|
# --source include/wait_for_binlog_checkpoint.inc
