--TEST--
|
|
Test connection resiliency with a prepared statement and transaction.
|
|
--DESCRIPTION--
|
|
Prepare a statement, break the connection, and execute the statement. Then
|
|
test transactions by breaking the connection before beginning a transaction
|
|
and in the middle of the transaction. The latter case should fail (i.e., the
|
|
transaction should be rolled back).
