python – 原型文件系统

In the long run,should any
respectable filesystem implementation
be in C? Will not being in C hamper
portability,or eventually cause
performance issues?

不一定,有很多与C不同的表演语言(O’Caml,C是第一个想到的.)实际上,我希望NTFS用C语言编写.你似乎是来自Linux背景,并且由于Linux内核是用C语言编写的,任何希望合并到内核中的文件系统也必须用C语言编写.

Are there other implementations like
FUSE?

Windows有一对,例如http://code.google.com/p/winflux/和http://dokan-dev.net/en/,各种成熟度级别

Evidently core filesystem technology
moves slowly (fat32,
everything else is small fish),what
debugging techniques are employed?

同样,在Windows中大多数情况下都是如此,在Solaris中有ZFS,在Linux ext4和btrfs中存在.调试技术通常涉及在各种操作过程中关闭机器并查看剩余的状态数据,存储大量数据并查看性能.

What is the general course filesystem
development takes in arriving at a
highly optimized,fully supported
implementation in major OSs?

同样,这取决于哪个操作系统,但它确实涉及相当多的测试,尤其是确保故障不会丢失数据.
