## Envoy/Istio WebAssembly 扩展实现原理 ... 边鹏远 (github: bianpengyuan) ## 目录 Wasm 和 V8 engine 简介 Wasm 扩展对于Envoy的意义 Wasm 扩展在 Envoy 的实现原理 Wasm 扩展在 Istio 的应用 未来工作 ## WebAssembly “WebAssembly (abbreviated 1) 当 Envoy 主线程加载带有 Wasm 扩展的 listener 时，开始创建一个 V8 Isolate，并且将 Envoy 对于 Wasm ABI 实现注入到创建的 Context 2) V8 加载，解析，编译 Wasm module 3) Envoy Wasm runtime 从 V8 Isolate 中读取扩展实现 至此，主线程完成创建 Base Wasm 实例（模板 Wasm 1.jpg) ## 性能开销 ## ☐ 内存 ☐ Wasm module 代码: 占用 xxx Kb 到 x Mb 不等 ☐ Wasm 运行时的线性内存 ☐ V8 自身运行内存：~10 Mb ## ☐ CPU ☐ V8 背景线程 ☐ C++ 到 Wasm 之间的切换 Envoy::Http::HeaderMapImpl::StaticLookupTable

What is Deno ## “Deno 是基于 V8 并采用 Rust 构建的, 一个简单、现代且安全的 JavaScript 和 TypeScript 运行时环境。” Deno is a simple, modern and secure runtime for JavaScript and TypeScript that uses V8 and is built in Rust. https://deno land/ ## Deno / 基于 V8 V8 是一个由 Google 开发的开源 JavaScript 引擎，其在运行之前将 JavaScript 编译成了机器代码，而非字节码或是解释执行它，以此提升性能。更进一步，使用了如 Inline Cache 等方法来提高性能。有了这些功能，JavaScript 程序与 V8 引擎的速度媲美二进制编译。在 Deno 中，V8 引擎用于执行 JavaScript Rust 构建 Rust 是由 Mozilla 主导开发的通用、编译型编程语言。设计准则为 “安全、并发、实用”，支持函数式、并发式、过程式以及面向对象的编程风格。Deno 使用 Rust 语言来封装 V8 引擎，通过 libdeno 绑定，我们就可以在 JavaScript 中调用隔离的功能。 ## Deno / 简单 1. 天生支持 TypeScript - 使用 Deno 运行 TypeScript

tremendous amount of flexibility via configuration. For more information, The Conda Configuration Engine for Power Users blog post is a good resource. ## Deprecations/Breaking Changes • the conda ‘root’ directory (#3186) ###### 4.4.144 4.2.0 (2016-07-28) Configuration ## New Features • New Configuration Engine: Configuration and “operating context” are the foundation of conda’s functionality. Conda now has configuration. Full documentation updates pending. (#2537, #3160, #3178) • New Exception Handling Engine: Previous releases followed a pattern of premature exiting (with hard calls to sys.exit() when exceptional
