Ruby内存管理 [英] Ruby Memory Management

问题描述

我一直在使用Ruby一段时间，我发现，对于更大的项目，它可以占用相当大的内存。

• 请让每个答案都有一个最佳实践，让社群投票

不要这样做：





  def方法（x）
 x.split（不管args是什么）
 end 
  

或：

  def方法（x）
 x.gsub（无论参数是什么）
 end 
  

这两者都将永久性地泄露ruby 1.8的内存。 5和1.8.6 。 （不知道1.8.7，因为我没有尝试过，但我真的希望它是固定的。）解决方法是愚蠢的，涉及创建一个局部变量。你不必使用本地，只需创建一个...





这就是为什么我对ruby语言有很多的爱，但不尊重MRI




I have been using Ruby for a while now and I find, for bigger projects, it can take up a fair amount of memory. What are some best practices for reducing memory usage in Ruby?

Don't do this:

def method(x)
  x.split( doesn't matter what the args are )
end

or this:

def method(x)
  x.gsub( doesn't matter what the args are )
end

Both will permanently leak memory in ruby 1.8.5 and 1.8.6. (not sure about 1.8.7 as I haven't tried it, but I really hope it's fixed.) The workaround is stupid and involves creating a local variable. You don't have to use the local, just create one...

Things like this are why I have lots of love for the ruby language, but no respect for MRI
