文件系统

Embedded systems are usually diskless systems. In order to keep permanent data in the systems, it is a widely adapted strategy to use flash memory disk as its disk system, therefore how to build a flash memory file system is the focus of this thesis in a reasonable embedded system.

嵌入式系统通常是无磁盘系统，为了让嵌入式系统能够永久性保存资料，使用Flash 存储器是一种普遍的策略，那么如何在嵌入式系统环境中建立Flash 存储器文件系统就成为了本文研究和解决的重要问题。

Unlike the permanent address spaces of storage media, files may be created and deleted, and in most file systems, may expand or contract in size during their lifetimes.

与存储介质的固定编址空间不同的是，文件可以被创建或者删除，并且在大多数的文件系统中，文件的大小在其生命周期内可以增加或者减小。

The HA function for the transaction service uses network file locking, and different file systems have different file locking behaviors.

Deleting files merely removes the file system's pointer to the file, ALL THE DATA REMAINS ON YOUR HARD DRIVE OR FLOPPY DISK.

Server agent coded by writer is presented in detail through the SART method,and some creative key technologies are analyzed such as the combination of the software signal、the properties of process and process communication that not only solved the real monitoring problem;the adoption of the UNIX phoney system-PROCFS that not only solved the real monitoring problem;Encoding and decoding to SNMP message on BER-solved the problem on monitor between several operating system.

文章最后给出了笔者负责编写的服务器代理的实现技术，采用SART方法对服务器代理的整体框架和各组成模块进行了详细描述，并对编码过程中的一些创新技术进行了分析，如：将UNIX系统中软件中断信号、UNIX进程的特性和进程间通信有机的结合起来，解决了代理的启动/关闭进程、探测进程状态等实际监控难题；利用UNIX系统的伪文件系统PROCFS进行资源探测，解决了系统中不能用SNMP进行探测的实际监控难题；采用BER编码规范对SNMP报文编码和解码，解决了系统中利用SNMP进行跨平台监控的难题。

Issuance, revision,superseding and withdrawl of all documents should be controlled with maintenance of revision histories.

Python provides standard access to both the stdio filesystem (through the built-in open function), as well as lower-level descriptor-based files (with the built-in os module).

Python对两种文件都提供了标准的访问方法：stdio文件系统（通过内置的open函数），以及低级的以描述符为基础的文件。
