-# How to build Bun
-
-## CMake
-
-Bun is built using CMake, which you can find in `CMakeLists.txt` and in the `cmake/` directory.
-
-* `CMakeLists.txt`
-* `cmake/`
-  * `Globals.cmake` - macros and functions used by all the other files
-  * `Options.cmake` - build options for configuring the build (e.g. debug/release mode)
-  * `CompilerFlags.cmake` - compiler and linker flags used by all the targets
-  * `tools/` - setup scripts for various build tools (e.g. llvm, zig, webkit, rust, etc.)
-  * `targets/` - targets for bun and its dependencies (e.g. brotli, boringssl, libuv, etc.)
-
-## How to
-
-There are `package.json` scripts that make it easy to build Bun without calling CMake directly, for example:
-
-```sh
-bun run build # builds a debug build: `build/debug/bun-debug`
-bun run build:release # builds a release build: `build/release/bun`
-bun run build:assert # builds a release build with debug assertions: `build/assert/bun`

-# Writing HMR/Dev Server tests
-
-Dev server tests validate that hot-reloading is robust, correct, and reliable. Remember to write thorough, yet concise tests.
-
-## File Structure
-
-- `test/bake/bake-harness.ts` - shared utilities and test harness
-  - primary test functions `devTest` / `prodTest` / `devAndProductionTest`
-  - class `Dev` (controls subprocess for dev server)
-  - class `Client` (controls a happy-dom subprocess for having the page open)
-  - more helpers
-- `test/bake/client-fixture.mjs` - subprocess for what `Client` controls. it loads a page and uses IPC to query parts of the page, run javascript, and much more.
-- `test/bake/dev/*.test.ts` - these call `devTest` to test dev server and hot reloading
-- `test/bake/dev-and-prod.ts` - these use `devAndProductionTest` to run the same test on dev and production mode. these tests cannot really test hot reloading for obvious reasons.
-
-## Categories
-
-bundle.test.ts - Bundle tests are tests concerning bundling bugs that only occur in DevServer.
-css.test.ts - CSS tests concern bundling bugs with CSS files
-plugins.test.ts - Plugin tests concern plugins in development mode.
-ecosystem.test.ts - These tests involve ensuring certain libraries are correct. It is preferred to test more concrete bugs than testing entire packages.
-esm.test.ts - ESM tests are about various esm features in development mode.
-html.test.ts - HTML tests are tests relating to HTML files themselves.
-react-spa.test.ts - Tests relating to React, our react-refresh transform, and basic server component transforms.
-sourcemap.test.ts - Tests verifying source-maps are correct.
-
-## `devTest` Basics
-
-A test takes in two primary inputs: `files` and `async test(dev) {`
-
-```ts
-import { devTest, emptyHtmlFile } from "../bake-harness";
-
-devTest("html file is watched", {
-  files: {
-    "index.html": emptyHtmlFile({
-      scripts: ["/script.ts"],
-      body: "<h1>Hello</h1>",
-    }),
-    "script.ts": `
-      console.log("hello");
-    `,
-  },
-  async test(dev) {
-    await dev.fetch("/").expect.toInclude("<h1>Hello</h1>");
-    await dev.fetch("/").expect.toInclude("<h1>Hello</h1>");
-    await dev.patch("index.html", {
-      find: "Hello",
-      replace: "World",
-    });
-    await dev.fetch("/").expect.toInclude("<h1>World</h1>");
-
-    // Works
-    await using c = await dev.client("/");
-    await c.expectMessage("hello");
-
-    // Editing HTML reloads
-    await c.expectReload(async () => {
-      await dev.patch("index.html", {
-        find: "World",
-        replace: "Hello",
-      });
-      await dev.fetch("/").expect.toInclude("<h1>Hello</h1>");
-    });
-    await c.expectMessage("hello");
-
-    await c.expectReload(async () => {
-      await dev.patch("index.html", {
-        find: "Hello",
-        replace: "Bar",
-      });
-      await dev.fetch("/").expect.toInclude("<h1>Bar</h1>");
-    });
-    await c.expectMessage("hello");
-
-    await c.expectReload(async () => {
-      await dev.patch("script.ts", {
-        find: "hello",
-        replace: "world",
-      });
-    });
-    await c.expectMessage("world");
-  },
-});
-```
-
-`files` holds the initial state, and the callback runs with the server running. `dev.fetch()` runs HTTP requests, while `dev.client()` opens a browser instance to the code.
-
-Functions `dev.write` and `dev.patch` and `dev.delete` mutate the filesystem. Do not use `node:fs` APIs, as the dev server ones are hooked to wait for hot-reload, and all connected clients to recieve changes.
-
-When a change performs a hard-reload, that must be explicitly annotated with `expectReload`. This tells `client-fixture.mjs` that the test is meant to reload the page once; All other hard reloads automatically fail the test.
-
-Client's have `console.log` instrumented, so that any unasserted logs fail the test. This makes it more obvious when an extra reload or re-evaluation. Messages are awaited via `c.expectMessage("log")` or with multiple arguments if there are multiple logs.
-
-## Testing for bundling errors
-
-By default, a client opening a page to an error will fail the test. This makes testing errors explicit.
-
-```ts
-devTest("import then create", {
-  files: {
-    "index.html": `
-      <!DOCTYPE html>
-      <html>
-      <head></head>
-      <body>
-        <script type="module" src="/script.ts"></script>
-      </body>
-      </html>
-    `,
-    "script.ts": `
-      import data from "./data";
-      console.log(data);
-    `,
-  },
-  async test(dev) {
-    const c = await dev.client("/", {
-      errors: ['script.ts:1:18: error: Could not resolve: "./data"'],
-    });
-    await c.expectReload(async () => {
-      await dev.write("data.ts", "export default 'data';");
-    });
-    await c.expectMessage("data");
-  },
-});
-```
-
-Many functions take an options value to allow specifying it will produce errors. For example, this delete is going to cause a resolution failure.
-
-```ts
-await dev.delete("other.ts", {
-  errors: ['index.ts:1:16: error: Could not resolve: "./other"'],
-});
-```

-# Implementing JavaScript classes in C++
-
-If there is a publicly accessible Constructor and Prototype, then there are 3 classes:
-
-- IF there are C++ class members we need a destructor, so `class Foo : public JSC::DestructibleObject`, if no C++ class fields (only JS properties) then we don't need a class at all usually. We can instead use JSC::constructEmptyObject(vm, structure) and `putDirectOffset` like in [NodeFSBinding.cpp](mdc:src/bun.js/bindings/NodeFSBinding.cpp).
-- class FooPrototype : public JSC::JSNonFinalObject
-- class FooConstructor : public JSC::InternalFunction
-
-If there is no publicly accessible Constructor, just the Prototype and the class is necessary. In some cases, we can avoid the prototype entirely (but that's rare).
-
-If there are C++ fields on the Foo class, the Foo class will need an iso subspace added to [DOMClientIsoSubspaces.h](mdc:src/bun.js/bindings/webcore/DOMClientIsoSubspaces.h) and [DOMIsoSubspaces.h](mdc:src/bun.js/bindings/webcore/DOMIsoSubspaces.h). Prototype and Constructor do not need subspaces.
-
-Usually you'll need to #include "root.h" at the top of C++ files or you'll get lint errors.
-
-Generally, defining the subspace looks like this:
-```c++
-
-class Foo : public JSC::DestructibleObject {
-
-// ...
-
- template<typename MyClassT, JSC::SubspaceAccess mode>
-    static JSC::GCClient::IsoSubspace* subspaceFor(JSC::VM& vm)
-    {
-        if constexpr (mode == JSC::SubspaceAccess::Concurrently)
-            return nullptr;
-        return WebCore::subspaceForImpl<MyClassT, WebCore::UseCustomHeapCellType::No>(
-            vm,
-            [](auto& spaces) { return spaces.m_clientSubspaceFor${MyClassT}.get(); },
-            [](auto& spaces, auto&& space) { spaces.m_clientSubspaceFor${MyClassT} = std::forward<decltype(space)>(space); },
-            [](auto& spaces) { return spaces.m_subspaceFo${MyClassT}.get(); },
-            [](auto& spaces, auto&& space) { spaces.m_subspaceFor${MyClassT} = std::forward<decltype(space)>(space); });
-    }
-
-
-```
-
-It's better to put it in the .cpp file instead of the .h file, when possible.
-
-## Defining properties
-
-Define properties on the prototype. Use a const HashTableValues like this:
-```C++

-    }
-};
-```
-
-
-### Structure caching
-
-If there's a class, prototype, and constructor:
-
-1. Add the `JSC::LazyClassStructure` to [ZigGlobalObject.h](mdc:src/bun.js/bindings/ZigGlobalObject.h)
-2. Initialize the class structure in [ZigGlobalObject.cpp](mdc:src/bun.js/bindings/ZigGlobalObject.cpp) in `void GlobalObject::finishCreation(VM& vm)`
-3. Visit the class structure in visitChildren in [ZigGlobalObject.cpp](mdc:src/bun.js/bindings/ZigGlobalObject.cpp) in `void GlobalObject::visitChildrenImpl`
-
-```c++#ZigGlobalObject.cpp
-void GlobalObject::finishCreation(VM& vm) {
-// ...
-    m_JSStatsBigIntClassStructure.initLater(
-        [](LazyClassStructure::Initializer& init) {
-            // Call the function to initialize our class structure.
-            Bun::initJSBigIntStatsClassStructure(init);
-        });
-```
-
-Then, implement the function that creates the structure:
-```c++
-void setupX509CertificateClassStructure(LazyClassStructure::Initializer& init)
-{
-    auto* prototypeStructure = JSX509CertificatePrototype::createStructure(init.vm, init.global, init.global->objectPrototype());
-    auto* prototype = JSX509CertificatePrototype::create(init.vm, init.global, prototypeStructure);
-
-    auto* constructorStructure = JSX509CertificateConstructor::createStructure(init.vm, init.global, init.global->functionPrototype());
-
-    auto* constructor = JSX509CertificateConstructor::create(init.vm, init.global, constructorStructure, prototype);
-
-    auto* structure = JSX509Certificate::createStructure(init.vm, init.global, prototype);
-    init.setPrototype(prototype);
-    init.setStructure(structure);
-    init.setConstructor(constructor);
-}
-```
-
-If there's only a class, use `JSC::LazyProperty<JSGlobalObject, Structure>` instead of `JSC::LazyClassStructure`:
-
-1. Add the `JSC::LazyProperty<JSGlobalObject, Structure>` to @ZigGlobalObject.h
-2. Initialize the class structure in @ZigGlobalObject.cpp in `void GlobalObject::finishCreation(VM& vm)`
-3. Visit the lazy property in visitChildren in @ZigGlobalObject.cpp in `void GlobalObject::visitChildrenImpl`
-void GlobalObject::finishCreation(VM& vm) {
-// ...
-   this.m_myLazyProperty.initLater([](const JSC::LazyProperty<JSC::JSGlobalObject, JSC::Structure>::Initializer& init) {
-        init.set(Bun::initMyStructure(init.vm, reinterpret_cast<Zig::GlobalObject*>(init.owner)));
-    });
-```
-
-Then, implement the function that creates the structure:
-```c++
-Structure* setupX509CertificateStructure(JSC::VM &vm, Zig::GlobalObject* globalObject)
-{
-    // If there is a prototype:
-    auto* prototypeStructure = JSX509CertificatePrototype::createStructure(init.vm, init.global, init.global->objectPrototype());
-    auto* prototype = JSX509CertificatePrototype::create(init.vm, init.global, prototypeStructure);
-
-    // If there is no prototype or it only has 
-
-    auto* structure = JSX509Certificate::createStructure(init.vm, init.global, prototype);
-    init.setPrototype(prototype);
-    init.setStructure(structure);
-    init.setConstructor(constructor);
-}
-```
-
-
-Then, use the structure by calling `globalObject.m_myStructureName.get(globalObject)`
-
-```C++
-JSC_DEFINE_HOST_FUNCTION(x509CertificateConstructorConstruct, (JSGlobalObject * globalObject, CallFrame* callFrame))
-{
-    VM& vm = globalObject->vm();
-    auto scope = DECLARE_THROW_SCOPE(vm);
-
-    if (!callFrame->argumentCount()) {
-        Bun::throwError(globalObject, scope, ErrorCode::ERR_MISSING_ARGS, "X509Certificate constructor requires at least one argument"_s);
-        return {};
-    }
-
-    JSValue arg = callFrame->uncheckedArgument(0);
-    if (!arg.isCell()) {
-        Bun::throwError(globalObject, scope, ErrorCode::ERR_INVALID_ARG_TYPE, "X509Certificate constructor argument must be a Buffer, TypedArray, or string"_s);
-        return {};
-    }
-
-    auto* zigGlobalObject = defaultGlobalObject(globalObject);
-    Structure* structure = zigGlobalObject->m_JSX509CertificateClassStructure.get(zigGlobalObject);
-    JSValue newTarget = callFrame->newTarget();
-    if (UNLIKELY(zigGlobalObject->m_JSX509CertificateClassStructure.constructor(zigGlobalObject) != newTarget)) {
-        auto scope = DECLARE_THROW_SCOPE(vm);
-        if (!newTarget) {
-            throwTypeError(globalObject, scope, "Class constructor X509Certificate cannot be invoked without 'new'"_s);
-            return {};
-        }
-
-        auto* functionGlobalObject = defaultGlobalObject(getFunctionRealm(globalObject, newTarget.getObject()));
-        RETURN_IF_EXCEPTION(scope, {});
-        structure = InternalFunction::createSubclassStructure(
-            globalObject, newTarget.getObject(), functionGlobalObject->NodeVMScriptStructure());
-        scope.release();
-    }
-
-    return JSValue::encode(createX509Certificate(vm, globalObject, structure, arg));
-}
-```
-
-### Expose to Zig
-
-To expose the constructor to zig:
-
-```c++
-extern "C" JSC::EncodedJSValue Bun__JSBigIntStatsObjectConstructor(Zig::GlobalObject* globalobject)
-{
-    return JSValue::encode(globalobject->m_JSStatsBigIntClassStructure.constructor(globalobject));
-}
-```
-
-Zig:
-```zig
-extern "c" fn Bun__JSBigIntStatsObjectConstructor(*JSC.JSGlobalObject) JSC.JSValue;
-pub const getBigIntStatsConstructor =  Bun__JSBigIntStatsObjectConstructor;
-```
-
-To create an object (instance) of a JS class defined in C++ from Zig, follow the __toJS convention like this:
-```c++
-// X509* is whatever we need to create the object
-extern "C" EncodedJSValue Bun__X509__toJS(Zig::GlobalObject* globalObject, X509* cert)
-{
-    // ... implementation details
-    auto* structure = globalObject->m_JSX509CertificateClassStructure.get(globalObject);
-    return JSValue::encode(JSX509Certificate::create(globalObject->vm(), structure, globalObject, WTFMove(cert)));
-}
-```
-
-And from Zig:
-```zig
-const X509 = opaque {
-    // ... class 
-
-    extern fn Bun__X509__toJS(*JSC.JSGlobalObject, *X509) JSC.JSValue;
-    
-    pub fn toJS(this: *X509, globalObject: *JSC.JSGlobalObject) JSC.JSValue {
-        return Bun__X509__toJS(globalObject, this);
-    }
-};
-```

-# Writing tests for Bun
-
-## Where tests are found
-
-You'll find all of Bun's tests in the `test/` directory.
-
-* `test/`
-  * `cli/` - CLI command tests, like `bun install` or `bun init`
-  * `js/` - JavaScript & TypeScript tests
-    * `bun/` - `Bun` APIs tests, seperated by category, for example: `glob/` for `Bun.Glob` tests
-    * `node/` - Node.js module tests, seperated by module, for example: `assert/` for `node:assert` tests
-      * `test/` - Vendored Node.js tests, taken from the Node.js repository (does not conform to Bun's test style)
-    * `web/` - Web API tests, seperated by category, for example: `fetch/` for `Request` and `Response` tests
-    * `third_party/` - npm package tests, to validate that basic usage works in Bun
-  * `napi/` - N-API tests
-  * `v8/` - V8 C++ API tests
-  * `bundler/` - Bundler, transpiler, CSS, and `bun build` tests
-  * `regression/issue/[number]` - Regression tests, always make one when fixing a particular issue
-
-## How tests are written
-
-Bun's tests are written as JavaScript and TypeScript files with the Jest-style APIs, like `test`, `describe`, and `expect`. They are tested using Bun's own test runner, `bun test`. 
-
-```js
-import { describe, test, expect } from "bun:test";
-import assert, { AssertionError } from "assert";
-
-describe("assert(expr)", () => {
-  test.each([true, 1, "foo"])(`assert(%p) does not throw`, expr => {
-    expect(() => assert(expr)).not.toThrow();
-  });
-
-  test.each([false, 0, "", null, undefined])(`assert(%p) throws`, expr => {
-    expect(() => assert(expr)).toThrow(AssertionError);
-  });
-});
-```
-
-## Testing conventions
-
-* See `test/harness.ts` for common test utilities and helpers
-* Be rigorous and test for edge-cases and unexpected inputs
-* Use data-driven tests, e.g. `test.each`, to reduce boilerplate when possible
-* When you need to test Bun as a CLI, use the following pattern:
-
-```js
-import { test, expect } from "bun:test";
-import { spawn } from "bun";
-import { bunExe, bunEnv } from "harness";
-
-test("bun --version", async () => {
-  const { exited, stdout: stdoutStream, stderr: stderrStream } = spawn({
-    cmd: [bunExe(), "--version"],
-    env: bunEnv,
-    stdout: "pipe",
-    stderr: "pipe",
-  });
-  const [ exitCode, stdout, stderr ] = await Promise.all([
-    exited,
-    new Response(stdoutStream).text(),
-    new Response(stderrStream).text(),
-  ]);
-  expect({ exitCode, stdout, stderr }).toMatchObject({
-    exitCode: 0,
-    stdout: expect.stringContaining(Bun.version),
-    stderr: "",
-  });
-});
-```
-
-## Before writing a test
-
-* If you are fixing a bug, write the test first and make sure it fails (as expected) with the canary version of Bun
-* If you are fixing a Node.js compatibility bug, create a throw-away snippet of code and test that it works as you expect in Node.js, then that it fails (as expected) with the canary version of Bun
-* When the expected behaviour is ambigious, defer to matching what happens in Node.js
-* Always attempt to find related tests in an existing test file before creating a new test file

-Using `bun run build:local` will build Bun in the `./build/debug-local` directory (instead of `./build/debug`), you'll have to change a couple of places to use this new directory:
-
-- The first line in [`src/js/builtins.d.ts`](/src/js/builtins.d.ts)
-- The `CompilationDatabase` line in [`.clangd` config](/.clangd) should be `CompilationDatabase: build/debug-local`
-- In [`build.zig`](/build.zig), the `codegen_path` option should be `build/debug-local/codegen` (instead of `build/debug/codegen`)
-- In [`.vscode/launch.json`](/.vscode/launch.json), many configurations use `./build/debug/`, change them as you see fit
-
 Note that the WebKit folder, including build artifacts, is 8GB+ in size.
 
 If you are using a JSC debug build and using VScode, make sure to run the `C/C++: Select a Configuration` command to configure intellisense to find the debug headers.
 
-Note that if you change make changes to our [WebKit fork](https://github.com/oven-sh/WebKit), you will also have to change [`SetupWebKit.cmake`](/cmake/tools/SetupWebKit.cmake) to point to the commit hash.

-# express benchmark
-
-This benchmarks a hello world express server.
-
-To install dependencies:
-
-```bash
-bun install
-```
-
-To run in Bun:
-
-```sh
-bun ./express.mjs
-```
-
-To run in Node:
-
-```sh
-node ./express.mjs
-```
-
-To run in Deno:
-
-```sh
-deno run -A ./express.mjs
-```
-
-To benchmark each runtime:
-
-```bash
-oha http://localhost:3000 -n 500000 -H "Accept-Encoding: identity"
-```
-
-We recommend using `oha` or `bombardier` for benchmarking. We do not recommend using `ab`, as it uses HTTP/1.0 which stopped being used by web browsers in the early 2000s. We also do not recommend using autocannon, as the node:http client is not performant enough to measure the throughput of Bun's HTTP server.
-
-Note the `Accept-Encoding: identity` header exists to prevent Deno's HTTP server from compressing the response.

+# CI
+
+This directory contains scripts for building CI images for Bun.
+
+## Building
+
+### `macOS`
+
+On macOS, images are built using [`tart`](https://tart.run/), a tool that abstracts over the [`Virtualization.Framework`](https://developer.apple.com/documentation/virtualization) APIs, to run macOS VMs.
+
+To install the dependencies required, run:
+
+```sh
+$ cd ci
+$ bun run bootstrap
+```
+
+To build a vanilla macOS VM, run:
+
+```sh
+$ bun run build:darwin-aarch64-vanilla
+```
+
+This builds a vanilla macOS VM with the current macOS release on your machine. It runs scripts to disable things like spotlight and siri, but it does not install any software.
+
+> Note: The image size is 50GB, so make sure you have enough disk space.
+
+If you want to build a specific macOS release, you can run:
+
+```sh
+$ bun run build:darwin-aarch64-vanilla-15
+```
+
+> Note: You cannot build a newer release of macOS on an older macOS machine.
+
+To build a macOS VM with software installed to build and test Bun, run:
+
+```sh
+$ bun run build:darwin-aarch64
+```
+
+## Running
+
+### `macOS`
+
+## How To
+
+### Support a new macOS release
+
+1. Visit [`ipsw.me`](https://ipsw.me/VirtualMac2,1) and find the IPSW of the macOS release you want to build.
+
+2. Add an entry to [`ci/darwin/variables.pkr.hcl`](/ci/darwin/variables.pkr.hcl) with the following format:
+
+```hcl
+sonoma = {
+  distro  = "sonoma"
+  release = "15"
+  ipsw    = "https://updates.cdn-apple.com/..."
+}
+```
+
+3. Add matching scripts to [`ci/package.json`](/ci/package.json) to build the image, then test it:
+
+```sh
+$ bun run build:darwin-aarch64-vanilla-15
+```
+
+> Note: If you need to troubleshoot the build, you can remove the `headless = true` property from [`ci/darwin/image-vanilla.pkr.hcl`](/ci/darwin/image-vanilla.pkr.hcl) and the VM's screen will be displayed.
+
+4. Test and build the non-vanilla image:
+
+```sh
+$ bun run build:darwin-aarch64-15
+```
+
+This will use the vanilla image and run the [`scripts/bootstrap.sh`](/scripts/bootstrap.sh) script to install the required software to build and test Bun.
+
+5. Publish the images:
+
+```sh
+$ bun run login
+$ bun run publish:darwin-aarch64-vanilla-15
+$ bun run publish:darwin-aarch64-15
+```
