After you're done making changes, check the file back in with a meaningful change log message (see Listing 6).
在完成了相应的更改之后，使用有意义的更改日志消息再次签入该文件(请参见清单6)。

If not, in other words an entry does not exist, the server processes the log message and, if successful, creates an entry in the persistence log before the acknowledgement message is sent.
如果尚未被处理，换句话说，存储日志中不存在对应的条目，服务器将处理日志信息，如果处理成功，在返回确认消息之前，将在存储日志中创建一个条目。
If the required level is either atomic or semi-atomic, LogService does not persist the log message immediately. Instead, it keeps it in a safe area from where it can be retrieved during commit.
如果指定的级别是原子性或半原子性，日志服务不会将日志消息马上进行持续化处理，相反，它将这些日志信息保存在安全的地方，在提交过程中再将这些信息取回。
