github.com sqlc は何をやっているのか、問題に遭遇したときに調査するべき箇所はどこか？ というのを sqlc 1.20 時点の情報をもとに書いていきます。 背景 最近 sqlc に PR を送るようになり sqlc についての理解が深まってきたのでまとめておこうというのと理解を共有しておくことで PR を送る人が増えると良いなという思惑があります。 sqlc とは SQL Compiler の略でスキーマとクエリからパラメータと結果の型を推論するツールです。 その推論された型からコードを生成したり、lint のようなことが可能です。 コード生成が主な機能ですが v1.20 から sqlc vet が導入されています。 Linting queries — sqlc 1.21.0 documentation internals sqlc はスキーマとクエリからパラメータや結果の型

EngineeringOpen SourceGit’s database internals III: file history queriesGit’s file history queries use specialized algorithms that are tailored to common developer behavior. Level up your history spelunking skills by learning how different history modes behave and which ones to use when you need them. This week, we are exploring Git’s internals with the following concept in mind: Git is the distri
Scheduling Internals
A sneak peek to what's coming! I remember when I first learned that you can write a server handling millions of clients running on just a single thread, my mind was simply blown away 🤯 I used Node.js while knowing it is single threaded, I used async / await in Python, and I used threads, but never asked myself "How is any of this possible?". This post is written to spread the genius of concurrenc
PostgreSQL 14 Internals
I’m excited to announce that the translation of the “PostgreSQL 14 Internals” book is finally complete thanks to the amazing work of Liudmila Mantrova. The final part of the book considers each of the index types in great detail. It explains and demonstrates how access methods, operator classes, and data types work together to serve a variety of distinct needs. You can download a PDF version of th
In this five part series, we will "recreate" React from the ground up, learning how it works along the way. Once we have finished, you should have a good grasp of how React works, and when and why it calls the various lifecycle methods of a component. This series is based on React 15.3, in particular using ReactDOM and the stack reconciler. React 16 and beyond have changed a lot. I still think thi
Node.js is an interesting tool for web developers. With its high level of concurrency, it has become a leading candidate for people choosing tools to use in web development. In this article, we will learn about what makes up Node.js, give it a meaningful definition, understand how the internals of Node.js interact with one another, and explore the project repository for Node.js on GitHub. Since th
Zig Build System Internals
Zig has a built-in build system for building projects. It runs on every platform Zig supports and is capable of building everything from simple executables and libraries to complex, multi-artifact, multi-step projects. This page will dive into how the internals of the Zig build system works. Build systems are an extremely important detail of any software project. When they work, they can feel like
async-task is one of the most complicated crates in the smol ecosystem. But, fundamentally, it’s just a future on the heap. I pride myself on smol packages being very easy to parse for anyone with a beginner’s level of experience in Rust. By that I mean, if you want to know how smol works, it should be very easy to pick up the source code, read through it, and understand how each individual part w
