Reactor:深入理解reactor core
在上一篇文章中,我们简要回顾了Reactor的发展历程和基本的Flux和Mono操作。本文将深入探讨Reactor的高级用法,让我们一起继续探索。
自定义Subscriber的使用更为灵活。之前介绍的简单的android源码Flux订阅方法需要通过lambda表达式来定义四个消费行为:consumer、errorConsumer、completeConsumer和subscriptionConsumer。这显得有些复杂,是否能通过一个更简洁的方式来实现呢?答案是肯定的,Reactor提供了subscribe方法,接受一个Subscriber实例,商城客服源码这样就集成了所有功能。
直接使用Reactor提供的BaseSubscriber类,可以避免手动编写Subscriber的繁琐。BaseSubscriber是一个抽象类,它实现了Subscriber的所有功能,并提供了一些额外方法。但是要注意,BaseSubscriber是单次使用的,一旦订阅第二个Publisher,第一个的订阅就会被取消。
为了自定义需求,shell 存活源码我们需要继承BaseSubscriber并重写特定的方法。例如,CustSubscriber重写了hookOnSubscribe和hookOnNext方法,允许在订阅开始和接收下一个值时执行自定义操作,如调用request方法控制接收速率。
Reactor支持Backpressure处理,即当消费者处理速度跟不上生产者时,可以调整生产者的速率。BaseSubscriber的hookOnSubscribe默认设置为无限请求,但通过重写该方法,我们可以定制处理速度。摇红包源码此外,Flux的limitRate方法可以限制subscriber接收数据的速度。
创建Flux有多种方式,包括同步的generate、异步的create、支持多线程操作的push以及实例方法Handle。generate用于同步生成元素,create则可用于将第三方异步API与Flux连接。push是单线程的,而Handle则像generate一样处理SynchronousSink,但参数为无返回值的装修erp源码BiConsumer。
初步认识Twisted
摘自 第三部分:初步认识Twisted_stulife_新浪博客
Reactor
首先我们先稍微写点简单的twisted程序来认识一下twisted。
正如在第二部分所说的那样,twisted是实现了Reactor模式的,因此它必然会有一个对象来代表这个reactor或者说是事件循环,而这正是twisted的核心。上面代码的第一行引入了reactor,第二行开始启动事件循环。
这个程序什么事情也不做。除非你通过ctrl+c来终止它,否则它会一直运行下去。通常会为循环提供一到多个文件描述符(连接到,例如,一个诗歌服务器),以便监控I/O。后面我们会来介绍这部分内容,现在这里的reactor被卡住了。值得注意的是,这里并不是一个在不停运行的简单循环。实际上,这个reactor被卡住在第二部分图5的最顶端,等待永远不会到来的事件发生(具体来说,等待一个没有文件描述符的selectcall)。
下面我们会让这个程序丰富起来,不过事先要说几个
1.Twisted的reactor只有通过调用reactor.run()来启动。2.The reactor loop runs in the same thread it was started in. In this case, it runs in the main (and only) thread.3.一旦启动,就会一直运行下去。The reactor is now “in control” of the program (or the specific thread it was started in).4.If it doesn’t have anything to do, the reactor loop does not consume CPU.5.The reactor isn’t created explicitly, just imported.
最后一条需要解释一下。In Twisted, the reactor is basically a Singleton. There is only one reactor object and it is created implicitly when you import it.
Twisted includes several reactor implementations that use a variety of different methods. For example, twisted.internet.pollreactor uses the poll system call instead of select.
To use a specific reactor, you mustinstall it before importingtwisted.internet.reactor. Here is how you install the pollreactor:
If you importtwisted.internet.reactorwithout first installing a specific reactor implementation, then Twisted will install the default reactor for you. The particular one you get will depend on the operating system and Twisted version you are using.
For that reason, it is general practice not to import the reactor at the top level of modules to avoid accidentally installing the default reactor. Instead, import the reactor in the same scope in which you use it.
使用pollreactor重写上面的程序:
上面这段代码同样没有做任何事情。
Callback
A callback is a function reference that we give to Twisted (or any other framework) that Twisted will use to “call us back” at the appropriate time.
Since Twisted’s loop is separate from our code, most interactions between the reactor core and our business logic will begin with a callback to a function we gave to Twisted using various APIs.
有关回调的一些其它说明:
Figure 6 illustrates some important properties of callbacks:
During a callback, the Twisted loop is effectively “blocked” on our code. So we should make sure our callback code doesn’t waste any time. In particular, we should avoid making blocking I/O calls in our callbacks. Otherwise, we would be defeating the whole point of using the reactor pattern in the first place. Twisted will not take any special precautions to prevent our code from blocking, we just have to make sure not to do it.
Other examples of potentially blocking operations include reading or writing from a non-socket file descriptor (like a pipe) or waiting for a subprocess to finish.
Exactly how you switch from blocking to non-blocking operations is specific to what you are doing, but there is often a Twisted API that will help you do it.
Note that many standard Python functions have no way to switch to a non-blocking mode. For example, theos.systemfunction will always block until the subprocess is finished. That’s just how it works. So when using Twisted, you will have to eschewos.systemin favor of the Twisted API for launching subprocesses.
Goodbye, Twisted
It turns out you can tell the Twisted reactor to stop running by using the reactor’sstop method. But once stopped the reactor cannot be restarted, so it’s generally something you do only when your program needs to exit.
Here’s a program which stops the reactor after a 5 second countdown:
This program uses thecallLater API to register a callback with Twisted. With callLater the callback is the second argument and the first argument is the number of seconds in the future you would like your callback to run.
So how does Twisted arrange to execute the callback at the right time? Since this program doesn’t listen on any file descriptors, why doesn’t it get stuck in theselect loop like the others? The select call, and the others like it, also accepts an optional timeout value. If a timeout value is supplied and no file descriptors have become ready for I/O within the specified time then theselect call will return anyway. Incidentally, by passing a timeout value of zero you can quickly check (or “poll”) a set of file descriptors without blocking at all.
You can think of a timeout as another kind of event the event loop of Figure 5 is waiting for. And Twisted uses timeouts to make sure any “timed callbacks” registered withcallLaterget called at the right time. Or rather, at approximately the right time. If another callback takes a really long time to execute, a timed callback may be delayed past its schedule. Twisted’scallLatermechanism cannot provide the sort of guarantees required in a hard real-time system.
Here is the output of our countdown program:
由于Twisted经常会在回调中结束调用我们的代码,因此你可能会想,如果我们的回调函数中出现异常会发生什么状况。
reactor并不会因为回调函数中出现失败(虽然它会报告异常)而停止运行。网络服务器通常需要这种健壮的软件。它们通常不希望由于一个随机的Bug导致崩溃。
