It is absolutely idiotic to have 64-bit pointers when I compile a program that uses less than 4 gigabytes of RAM. When such pointer values appear inside a struct, they not only waste half the memory, they effectively throw away half of the cache.
While the title of this post may suggest taking a deep dive into a collection of books around oil pans – which, considering construction norms for pans, is a topic with a surprising amount of literature – we are instead looking a bit closer at Oilpan, a C++ garbage collector that is hosted through V8 as a library since V8 v9.4.
In the past we have already been writing about garbage collection for JavaScript, the document object model (DOM), and how all of this is implemented and optimized in V8. Not everything in Chromium is JavaScript though, as most of the browser and its Blink rendering engine where V8 is embedded are written in C++. JavaScript can be used to interact with the DOM that is then processed by the rendering pipeline.
