except c2932.
Bug#37232 and bug#31183 were fixed in the 6.0 branch only.
They should be fixed in the plugin too, specially MySQL 6.0
is discontinued at this point.

Relax locking behaviour for REPLACE INTO t SELECT ... FROM t1.
Now SELECT on t1 is performed as a consistent read when the isolation
level is set to READ COMMITTED.

Added a comment to clarify why distinct calls to read MySQL binary
log file name and log position do not entail any race condition.

branches/6.0 bug#31183
If the system tablespace runs out of space because 'autoextend' is
not specified with innodb_data_file_path there was no error message
printed to the error log. The client would get 'table full' error.
This patch prints an appropriate error message to the error log.
