V8/Node.js 增加最大允许字符串长度 [英] V8/Node.js increase max allowed String length

问题描述

AFAIK V8 对允许的长度有一个已知的硬限制<代码>字符串s.尝试解析 >500MB 的字符串会弹出错误:

AFAIK V8 has a known hard limit on the length of allowed Strings. Trying to parse >500MB Strings will pop the error:

Invalid String Length

使用 V8 标志来增加堆大小没有任何区别

Using V8 flags to increase the heap size doesn't make any difference

$ node --max_old_space_size=5000 process-large-string.js

我知道我应该改用 Streams.但是有没有办法增加允许的最大 String 长度?

I know that I should be using Streams instead. However is there any way to increase the maximum allowed String length anyway?

更新:下面@PaulIrish 的回答表明他们将其提高到 1GB - 但它仍然不是用户可配置的

Update: Answer from @PaulIrish below indicates they upped it to 1GB - but it's still not user-configurable

推荐答案

抱歉，没有，没有办法增加允许的最大 String 长度.

Sorry, no, there is no way to increase the maximum allowed String length.

它在源代码中是硬编码的，并且很多代码都隐含地依赖它，所以虽然允许更大的字符串出现在人们的愿望清单上，但这将是很多工作并且不会发生在不久的将来.

It is hard-coded in the source, and a lot of code implicitly relies on it, so while allowing larger strings is known to be on people's wishlist, it is going to be a lot of work and won't happen in the near future.
