mariadb/mysql-test/suite/binlog_encryption/rpl_semi_sync.result
Andrei Elkin e972125f11 MDEV-13073 This part merges the Ali semisync related changes 
and specifically the ack receiving functionality.
Semisync is turned to be static instead of plugin so its functions
are invoked at the same points as RUN_HOOKS.
The RUN_HOOKS and the observer interface remain to be removed by later
patch.

Todo:
  React on killed status by repl_semisync_master.wait_after_sync(). Currently
  Repl_semi_sync_master::commit_trx does not check the killed status.

  There were few bugfixes found that are present in mysql and its unclear
  whether/how they are covered. Those include:

  Bug#15985893: GTID SKIPPED EVENTS ON MASTER CAUSE SEMI SYNC TIME-OUTS
  Bug#17932935 CALLING IS_SEMI_SYNC_SLAVE() IN EACH FUNCTION CALL
                 HAS BAD PERFORMANCE
  Bug#20574628: SEMI-SYNC REPLICATION PERFORMANCE DEGRADES WITH A HIGH NUMBER OF THREADS
