  • Best allocating method for my needs?
    I think V8's memory management is here: https://github.com/v8/v8/blob/master/src/heap/heap.h
    Maybe you can look into how other fast VMs are storing their objects, e.g. JVM and V8.

    And the list goes on, and on.

    This is true for V8, which underlies NodeJS, and is the engine that powers most modern JavaScript:


    V8 was designed by the same engineers who built the Java Virtual Machine, and what techniques did they employ to build this massive piece of software that runs the modern web? Object oriented design, and design patterns.

    It's very probable people designing modern web applications for the FAANGs are not particularly aware of design patterns, or even maybe that MVC is a design pattern even if they are using it. It's possible many design patterns aren't useful for the types of problems they are solving, or could complicate matters if they used them haphazardly.

    But the engine driving every single JavaScript program, is built on top of a behemoth of object oriented, design pattern laden, software, written by FAANG engineers that I promise you understand design patterns extremely well.

    I'm not saying this is the end all, be all, of software design. Or that "modern" functional takes on software design (most functional languages and ideas predate OOP) aren't perfectly valid, or successful. Or even that they couldn't solve many of these problems.

    I'm just contesting any dogmatic rejection of what has actually been one of the most successful branches of software design.

  • Slitter: A slab allocator that trusts, but verifies
    news.ycombinator.com | 2021-08-04
    Well, unfortunately, address space isn't unlimited. In memory experience developing 64-bit wasm engines, the typical approach of reserving 8GB of memory for each wasm memory leads to address space exhaustion after only about 1000 memories (ofc, regardless of how many actual pages those memories use). Therefore for a long living VM that might load and unload hundreds or even thousands of programs, it's really important to clean up those reservations promptly.

    In V8, cleaning up the reservations for Wasm memories is ultimately tied to garbage collection of the JS heap, since JS objects can root memory. That led to the somewhat clunky need to retry allocation in a loop, running a full GC if allocation fails the first few times (https://github.com/v8/v8/blob/master/src/objects/backing-sto...).

  • JVM Anatomy Quark #26: Identity Hash Code
    news.ycombinator.com | 2021-07-20
    Yeah, I know that trick. I implemented an identity hashmap[1] inside of V8 that uses that, because JS objects don't have an identity hash code[2]. It uses the object address as the basis of the hash code, which means the table needs to be reorganized when the GC moves objects, which is done with a post-GC hook. The identity maps in V8 are generally short-lived.

    I am not aware of production JVMs that use this, because in the worst case they can use a lot more memory if a lot of objects end up needing hashcodes.

  • [AskJS] How does JavaScript generate pseudo-random numbers?
    The JS language specification doesn't specify the implementation of some methods of the Math object, this is up to the JS engines to decide, but it seems most of them (Google's v8, Mozilla's SpiderMonkey and Safari's engine) use XorShift128 Here's the definition in the header file in v8's source: https://github.com/v8/v8/blob/master/src/base/utils/random-number-generator.h#L119
    V8 uses xorshift128+ https://github.com/v8/v8/blob/master/src/base/utils/random-number-generator.h#L119
