### Test 1:
|
|
### - While a consistent snapshot transaction is executed,
|
|
### no external inserts should be visible to the transaction.
|
|
# Switch to connection con1
|
|
CREATE TABLE t1 (a INT) ENGINE=innodb;

|
|
# Switch to connection con1
|
|
SELECT * FROM t1;
|
|
a
|
|
COMMIT;
|
|
### Test 2:
|
|
### - For any non-consistent snapshot transaction, external
|
|
### committed inserts should be visible to the transaction.

### Test 3:

### - Bug#44664: valgrind warning for COMMIT_AND_CHAIN and ROLLBACK_AND_CHAIN
|
|
### Chaining a transaction does not retain consistency level.
