Arenas in Rust - In Pursuit of Laziness
There’s been some discussion about arenas in Rust recently, and I thought I’d write about them. Arenas aren’t something you would typically reach for in Rust so fewer people know about them; you only really see them in applications for various niche use cases. Usually you can use an arena by pulling in a crate and not using additional unsafe, so there’s no need to be particularly skittish around t
Garbage collection and closures
Me, Surma, and Jason were hacking on a thing, and discovered that garbage collection within a function doesn't quite work how we expected. function demo() { const bigArrayBuffer = new ArrayBuffer(100_000_000); const id = setTimeout(() => { console.log(bigArrayBuffer.byteLength); }, 1000); return () => clearTimeout(id); } globalThis.cancelDemo = demo(); With the above, bigArrayBuffer is leaked fore
Chromium Docs - The Rule Of 2
When you write code to parse, evaluate, or otherwise handle untrustworthy inputs from the Internet — which is almost everything we do in a web browser! — we like to follow a simple rule to make sure it's safe enough to do so. The Rule Of 2 is: Pick no more than 2 of untrustworthy inputs;unsafe implementation language; andhigh privilege. (drawing source here) Why?When code that handles untrustworth

Improving Firefox stability with this one weird trick – Mozilla Hacks - the Web developer blog
The first computer I owned shipped with 128 KiB of RAM and to this day I’m still jarred by the idea that applications can run out of memory given that even 15-year-old machines often shipped with 4 GiB of memory. And yet it’s one of the most common causes of instability experienced by users and in the case of Firefox the biggest source of crashes on Windows. As such, at Mozilla, we spend significa

Your Jest Tests are Leaking Memory
Jest is designed in a way that makes memory leaks likely if you’re not actively trying to squash them. For many test suites this isn’t a problem because even if tests leak memory, the tests don’t use enough memory to actually cause a crash. That is, until you add one more test and suddenly the suite comes apart. In this article, we’ll walk through why it’s so easy for Jest to leak memory, how to t
