Bug#319 if while a non-transactional slave is replicating a transaction possible problem only testing related: addressing reviewers' comments. mysql-test/suite/bugs/r/rpl_bug38205.result: new results. mysql-test/suite/bugs/t/rpl_bug38205.test: changing output per reviewer's offering. mysql-test/suite/rpl/r/rpl_start_stop_slave.result: new results. mysql-test/suite/rpl/t/rpl_start_stop_slave.test: refining tests for Bug #38205, Bug#319 to start slave with the necessary synchronization; changing output per reviewer's offering; removing redundant wait for stop.

# Verifying that STOP SLAVE does not interrupt excution of a group
|
|
# execution of events if the group can not roll back.
|
|
# Killing the sql thread continues to provide a "hard" stop (the
|
|
# part II, moved to the bugs suite as it's hard to make it
|
|
# deterministic with KILL).
|
|
#
|
|
|
|
#
|
|
# Part I. The being stopped sql thread finishes first the current group of
|
|
# events if the group contains an event on a non-transaction table.
