transaction abort

基本解释

“Weak-undo”: Like weak, plus a transaction may abort at any point, undoing its changes and restarting
“弱-撤销（Weak-undo）”：与“弱-1-锁”相同，并且允许事务在任何点异常中断，然后撤销修改并重新启动。
The log operation succeeds only on transaction commit, but a failure of the log operation doesn't cause the transaction to abort.
只有当事务提交的时候日志操作才会成功，但日志操作的失败并不会导致事务被中止。
If the application domain goes down after this method is called, and before the transaction is completed, the transaction might abort.
