使用 Twisted 进行非阻塞文件访问 [英] Non-blocking file access with Twisted

问题描述

我试图弄清楚是否存在使用扭曲的文件访问的事实上的模式.我看过的很多例子(twisted.python.log、twisted.persisted.dirdbm、twisted.web.static)实际上似乎并不担心文件访问的阻塞.

I'm trying to figure out if there is a defacto pattern for file access using twisted. Lots of examples I've looked at (twisted.python.log, twisted.persisted.dirdbm, twisted.web.static) actually don't seem to worry about blocking for file access.

似乎应该有一些明显的接口，可能是从 abstract.FileDescriptor 继承的，所有文件访问都应该作为生产者/消费者通过它.

It seems like there should be some obvious interface, probably inheriting from abstract.FileDescriptor, that all file access should be going through it as a producer/consumer.

我是否遗漏了一些东西，或者只是在异步编程中，twisted 的主要用途是用于网络，而它并没有真正用于其他文件描述符操作，而不是担心非阻塞 IO 的纯度?

Have I missed something or is it just that the primary use for twisted in asynchronous programming is for networking and it hasn't really been worked out for other file descriptor operations, not worrying about the purity of non-blocking IO ?
