VM execute hookThe PHP virtual machine (VM) is responsible for handling the PHP runtime. There is a function pointer that extensions can override within the VM called zend_execute_ex. If an extension uses this hook, all calls to functions or methods that are defined in PHP run through this hook. Although this was one of the most popular function-call-interception hooks prior to PHP 8, it had a num
Lint Night #1 に登壇した。 lintnight.connpass.com 当日のスライドは以下です。 今回は Kuniwak さんの方でそもそも「Lint とは？」といった前段の話をしていただけるというのと、"Lint" を冠したイベントを考えて、ここなら事前に求める前提知識をいくつか端折って話して良いだろうと RuboCop の内部構造に踏み込んだ話にしてみました。 今回内部のしくみに踏み込もうと思った時に思い出したのが『Ruby のしくみ』で、表紙はこのパロディになっています。 Rubyのしくみ -Ruby Under a Microscope- 作者:Pat Shaughnessyオーム社Amazon 私の発表の構文解析パートで出てきた書籍はこちら。Yacc の Ruby 版である Racc については『Ruby 256 本 無道編』が構文解析のしくみもろもろと一緒に紹
A decision that arises over and over when designing concurrent programs is whether to represent program state in control flow or as data. This post is about what that decision means and how to approach it. Done well, taking program state stored in data and storing it instead in control flow can make programs much clearer and more maintainable than they otherwise would be. Before saying much more,

GCC for New Contributors¶ This is an unofficial guide to GCC’s internals, aimed at new developers, and at plugin authors. Source: https://github.com/davidmalcolm/gcc-newbies-guide I’m a relative newcomer to GCC, so I thought it was worth documenting some of the hurdles I ran into when I started working on GCC, to try to make it easier for others to start hacking on GCC.

Collaboratively editing strings of text is a common desire in peer-to-peer applications. For example, a note-taking app might represent each document as a single collaboratively-edited string of text. The algorithm presented here is one way to do this. It comes from a family of algorithms called CRDTs, which I will not describe here. It's similar to the approaches taken by popular collaborative te

Before we dive in, let me provide some background. In 2013, a bunch of people signed the extensible web manifesto, in favor of an Extensible Web Platform. The goal is pretty obvious: elaborate new kind of standards, that provides authors freedom and flexibility to build their own features. The aim is to define low-level APIs, an access to the core of the browsers, and so, involve authors into the

Hi everyone, Yesterday (2021-03-28) two malicious commits were pushed to the php-src repo [1] from the names of Rasmus Lerdorf and myself.

While investigation is still underway, we have decided that maintaining our own git infras

This is the first of several posts exploring how git works under the hood.
