Update inspect-browser.test.ts

- Remove complex xdg-open testing (not implemented in current build)
- Increase timeout to 3 seconds to allow inspector to start properly
- Focus tests on core inspector functionality that actually works:
  - Inspector starts and shows "Bun Inspector" output
  - WebSocket listening endpoint is shown
  - Browser URL is displayed with correct format
  - Custom ports and IP addresses work correctly
  - TypeScript files are supported
  - Files with spaces in paths work

All 5 tests now pass with the debug build that includes --inspect-browser support.

+# Upgrading Bun's Self-Reported Node.js Version
+
+This guide explains how to upgrade the Node.js version that Bun reports for compatibility with Node.js packages and native addons.
+
+## Overview
+
+Bun reports a Node.js version for compatibility with the Node.js ecosystem. This affects:
+- `process.version` output
+- Node-API (N-API) compatibility
+- Native addon ABI compatibility
+- V8 API compatibility for addons using V8 directly
+
+## Files That Always Need Updates
+
+### 1. Bootstrap Scripts
+- `scripts/bootstrap.sh` - Update `NODEJS_VERSION=`
+- `scripts/bootstrap.ps1` - Update `$NODEJS_VERSION =`
+
+### 2. CMake Configuration
+- `cmake/Options.cmake`
+  - `NODEJS_VERSION` - The Node.js version string (e.g., "24.3.0")
+  - `NODEJS_ABI_VERSION` - The ABI version number (find using command below)
+
+### 3. Version Strings
+- `src/bun.js/bindings/BunProcess.cpp`
+  - Update `Bun__versions_node` with the Node.js version
+  - Update `Bun__versions_v8` with the V8 version (find using command below)
+
+### 4. N-API Version
+- `src/napi/js_native_api.h`
+  - Update `NAPI_VERSION` define (check Node.js release notes)
+
+## Files That May Need Updates
+
+Only check these if the build fails or tests crash after updating version numbers:
+- V8 compatibility files in `src/bun.js/bindings/v8/` (if V8 API changed)
+- Test files (if Node.js requires newer C++ standard)
+
+## Quick Commands to Find Version Info
+
+```bash
+# Get latest Node.js version info
+curl -s https://nodejs.org/dist/index.json | jq '.[0]'
+
+# Get V8 version for a specific Node.js version (replace v24.3.0)
+curl -s https://nodejs.org/dist/v24.3.0/node-v24.3.0-headers.tar.gz | tar -xzO node-v24.3.0/include/node/node_version.h | grep V8_VERSION
+
+# Get ABI version for a specific Node.js version
+curl -s https://nodejs.org/dist/v24.3.0/node-v24.3.0-headers.tar.gz | tar -xzO node-v24.3.0/include/node/node_version.h | grep NODE_MODULE_VERSION
+
+# Or use the ABI registry
+curl -s https://raw.githubusercontent.com/nodejs/node/main/doc/abi_version_registry.json | jq '.NODE_MODULE_VERSION."<version>"'
+```
+
+## Update Process
+
+1. **Gather version info** using the commands above
+2. **Update the required files** listed in the sections above
+3. **Build and test**:
+   ```bash
+   bun bd
+   bun bd -e "console.log(process.version)"
+   bun bd -e "console.log(process.versions.v8)"
+   bun bd test test/v8/v8.test.ts
+   bun bd test test/napi/napi.test.ts
+   ```
+
+4. **Check for V8 API changes** only if build fails or tests crash:
+   - Compare v8-function-callback.h between versions
+   - Check v8-internal.h for Isolate size changes
+   - Look for new required APIs in build errors
+
+## If Build Fails or Tests Crash
+
+The V8 API rarely has breaking changes between minor Node.js versions. If you encounter issues:
+1. Check build errors for missing symbols or type mismatches
+2. Compare V8 headers between old and new Node.js versions
+3. Most issues can be resolved by implementing missing functions or adjusting structures
+
+## Testing Checklist
+
+- [ ] `process.version` returns correct version
+- [ ] `process.versions.v8` returns correct V8 version  
+- [ ] `process.config.variables.node_module_version` returns correct ABI
+- [ ] V8 tests pass
+- [ ] N-API tests pass
+
+## Notes
+
+- Most upgrades only require updating version numbers
+- Major V8 version changes (rare) may require API updates
+- The V8 shim implements only APIs used by common native addons

+
+**CRITICAL**: Never use `bun <file>` directly. It will not have your changes.
+
+### Logging
+
+`BUN_DEBUG_$(SCOPE)=1` enables debug logs for a specific debug log scope.
+
+Debug logs look like this:

+# 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 receive 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"'],
+});
+```

+# Registering Functions, Objects, and Modules in Bun
+
+This guide documents the process of adding new functionality to the Bun global object and runtime.
+
+## Overview
+
+Bun's architecture exposes functionality to JavaScript through a set of carefully registered functions, objects, and modules. Most core functionality is implemented in Zig, with JavaScript bindings that make these features accessible to users.
+
+There are several key ways to expose functionality in Bun:
+
+1. **Global Functions**: Direct methods on the `Bun` object (e.g., `Bun.serve()`)
+2. **Getter Properties**: Lazily initialized properties on the `Bun` object (e.g., `Bun.sqlite`)
+3. **Constructor Classes**: Classes available through the `Bun` object (e.g., `Bun.ValkeyClient`)
+4. **Global Modules**: Modules that can be imported directly (e.g., `import {X} from "bun:*"`)
+
+## The Registration Process
+
+Adding new functionality to Bun involves several coordinated steps across multiple files:
+
+### 1. Implement the Core Functionality in Zig
+
+First, implement your feature in Zig, typically in its own directory in `src/`. Examples:
+
+- `src/valkey/` for Redis/Valkey client
+- `src/semver/` for SemVer functionality
+- `src/smtp/` for SMTP client
+
+### 2. Create JavaScript Bindings
+
+Create bindings that expose your Zig functionality to JavaScript:
+
+- Create a class definition file (e.g., `js_bindings.classes.ts`) to define the JavaScript interface
+- Implement `JSYourFeature` struct in a file like `js_your_feature.zig`
+
+Example from a class definition file:
+
+```typescript
+// Example from a .classes.ts file
+import { define } from "../../codegen/class-definitions";
+
+export default [
+  define({
+    name: "YourFeature",
+    construct: true,
+    finalize: true,
+    hasPendingActivity: true,
+    memoryCost: true,
+    klass: {},
+    JSType: "0b11101110",
+    proto: {
+      yourMethod: {
+        fn: "yourZigMethod",
+        length: 1,
+      },
+      property: {
+        getter: "getProperty",
+      },
+    },
+    values: ["cachedValues"],
+  }),
+];
+```
+
+### 3. Register with BunObject in `src/bun.js/bindings/BunObject+exports.h`
+
+Add an entry to the `FOR_EACH_GETTER` macro:
+
+```c
+// In BunObject+exports.h
+#define FOR_EACH_GETTER(macro) \
+    macro(CSRF) \
+    macro(CryptoHasher) \
+    ... \
+    macro(YourFeature) \
+```
+
+### 4. Create a Getter Function in `src/bun.js/api/BunObject.zig`
+
+Implement a getter function in `BunObject.zig` that returns your feature:
+
+```zig
+// In BunObject.zig
+pub const YourFeature = toJSGetter(Bun.getYourFeatureConstructor);
+
+// In the exportAll() function:
+@export(&BunObject.YourFeature, .{ .name = getterName("YourFeature") });
+```
+
+### 5. Implement the Getter Function in a Relevant Zig File
+
+Implement the function that creates your object:
+
+```zig
+// In your main module file (e.g., src/your_feature/your_feature.zig)
+pub fn getYourFeatureConstructor(globalThis: *JSC.JSGlobalObject, _: *JSC.JSObject) JSC.JSValue {
+    return JSC.API.YourFeature.getConstructor(globalThis);
+}
+```
+
+### 6. Add to Build System
+
+Ensure your files are included in the build system by adding them to the appropriate targets.
+
+## Example: Adding a New Module
+
+Here's a comprehensive example of adding a hypothetical SMTP module:
+
+1. Create implementation files in `src/smtp/`:
+
+   - `index.zig`: Main entry point that exports everything
+   - `SmtpClient.zig`: Core SMTP client implementation
+   - `js_smtp.zig`: JavaScript bindings
+   - `js_bindings.classes.ts`: Class definition
+
+2. Define your JS class in `js_bindings.classes.ts`:
+
+```typescript
+import { define } from "../../codegen/class-definitions";
+
+export default [
+  define({
+    name: "EmailClient",
+    construct: true,
+    finalize: true,
+    hasPendingActivity: true,
+    configurable: false,
+    memoryCost: true,
+    klass: {},
+    JSType: "0b11101110",
+    proto: {
+      send: {
+        fn: "send",
+        length: 1,
+      },
+      verify: {
+        fn: "verify",
+        length: 0,
+      },
+      close: {
+        fn: "close",
+        length: 0,
+      },
+    },
+    values: ["connectionPromise"],
+  }),
+];
+```
+
+3. Add getter to `BunObject+exports.h`:
+
+```c
+#define FOR_EACH_GETTER(macro) \
+    macro(CSRF) \
+    ... \
+    macro(SMTP) \
+```
+
+4. Add getter function to `BunObject.zig`:
+
+```zig
+pub const SMTP = toJSGetter(Bun.getSmtpConstructor);
+
+// In exportAll:
+@export(&BunObject.SMTP, .{ .name = getterName("SMTP") });
+```
+
+5. Implement getter in your module:
+
+```zig
+pub fn getSmtpConstructor(globalThis: *JSC.JSGlobalObject, _: *JSC.JSObject) JSC.JSValue {
+    return JSC.API.JSEmailClient.getConstructor(globalThis);
+}
+```
+
+## Best Practices
+
+1. **Follow Naming Conventions**: Align your naming with existing patterns
+2. **Reference Existing Modules**: Study similar modules like Valkey or S3Client for guidance
+3. **Memory Management**: Be careful with memory management and reference counting
+4. **Error Handling**: Use `bun.JSError!JSValue` for proper error propagation
+5. **Documentation**: Add JSDoc comments to your JavaScript bindings
+6. **Testing**: Add tests for your new functionality
+
+## Common Gotchas
+
+- Be sure to handle reference counting properly with `ref()`/`deref()`
+- Always implement proper cleanup in `deinit()` and `finalize()`
+- For network operations, manage socket lifetimes correctly
+- Use `JSC.Codegen` correctly to generate necessary binding code

+globs:

+# 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, separated by category, for example: `glob/` for `Bun.Glob` tests
+    * `node/` - Node.js module tests, separated 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, separated 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

+
+# Bun's JavaScriptCore Class Bindings Generator
+
+This document explains how Bun's class bindings generator works to bridge Zig and JavaScript code through JavaScriptCore (JSC).
+
+## Architecture Overview
+
+Bun's binding system creates a seamless bridge between JavaScript and Zig, allowing Zig implementations to be exposed as JavaScript classes. The system has several key components:
+
+1. **Zig Implementation** (.zig files)
+2. **JavaScript Interface Definition** (.classes.ts files)
+3. **Generated Code** (C++/Zig files that connect everything)
+
+## Class Definition Files
+
+### JavaScript Interface (.classes.ts)
+
+The `.classes.ts` files define the JavaScript API using a declarative approach:
+
+```typescript
+// Example: encoding.classes.ts
+define({
+  name: "TextDecoder",
+  constructor: true,
+  JSType: "object",
+  finalize: true,
+  proto: {
+    decode: {
+      // Function definition
+      args: 1,
+    },
+    encoding: {
+      // Getter with caching
+      getter: true,
+      cache: true,
+    },
+    fatal: {
+      // Read-only property
+      getter: true,
+    },
+    ignoreBOM: {
+      // Read-only property
+      getter: true,
+    },
+  },
+});
+```
+
+Each class definition specifies:
+
+- The class name
+- Whether it has a constructor
+- JavaScript type (object, function, etc.)
+- Properties and methods in the `proto` field
+- Caching strategy for properties
+- Finalization requirements
+
+### Zig Implementation (.zig)
+
+The Zig files implement the native functionality:
+
+```zig
+// Example: TextDecoder.zig
+pub const TextDecoder = struct {
+    // Expose generated bindings as `js` namespace with trait conversion methods
+    pub const js = JSC.Codegen.JSTextDecoder;
+    pub const toJS = js.toJS;
+    pub const fromJS = js.fromJS;
+    pub const fromJSDirect = js.fromJSDirect;
+
+    // Internal state
+    encoding: []const u8,
+    fatal: bool,
+    ignoreBOM: bool,
+
+    // Constructor implementation - note use of globalObject
+    pub fn constructor(
+        globalObject: *JSGlobalObject,
+        callFrame: *JSC.CallFrame,
+    ) bun.JSError!*TextDecoder {
+        // Implementation
+
+        return bun.new(TextDecoder, .{
+            // Fields
+        });
+    }
+
+    // Prototype methods - note return type includes JSError
+    pub fn decode(
+        this: *TextDecoder,
+        globalObject: *JSGlobalObject,
+        callFrame: *JSC.CallFrame,
+    ) bun.JSError!JSC.JSValue {
+        // Implementation
+    }
+
+    // Getters
+    pub fn getEncoding(this: *TextDecoder, globalObject: *JSGlobalObject) JSC.JSValue {
+        return JSC.JSValue.createStringFromUTF8(globalObject, this.encoding);
+    }
+
+    pub fn getFatal(this: *TextDecoder, globalObject: *JSGlobalObject) JSC.JSValue {
+        return JSC.JSValue.jsBoolean(this.fatal);
+    }
+
+    // Cleanup - note standard pattern of using deinit/deref
+    fn deinit(this: *TextDecoder) void {
+        // Release any retained resources
+        // Free the pointer at the end.
+        bun.destroy(this);
+    }
+
+    // Finalize - called by JS garbage collector. This should call deinit, or deref if reference counted.
+    pub fn finalize(this: *TextDecoder) void {
+        this.deinit();
+    }
+};
+```
+
+Key components in the Zig file:
+
+- The struct containing native state
+- `pub const js = JSC.Codegen.JS<ClassName>` to include generated code
+- Constructor and methods using `bun.JSError!JSValue` return type for proper error handling
+- Consistent use of `globalObject` parameter name instead of `ctx`
+- Methods matching the JavaScript interface
+- Getters/setters for properties
+- Proper resource cleanup pattern with `deinit()` and `finalize()`
+- Update `src/bun.js/bindings/generated_classes_list.zig` to include the new class
+
+## Code Generation System
+
+The binding generator produces C++ code that connects JavaScript and Zig:
+
+1. **JSC Class Structure**: Creates C++ classes for the JS object, prototype, and constructor
+2. **Memory Management**: Handles GC integration through JSC's WriteBarrier
+3. **Method Binding**: Connects JS function calls to Zig implementations
+4. **Type Conversion**: Converts between JS values and Zig types
+5. **Property Caching**: Implements the caching system for properties
+
+The generated C++ code includes:
+
+- A JSC wrapper class (`JSTextDecoder`)
+- A prototype class (`JSTextDecoderPrototype`)
+- A constructor function (`JSTextDecoderConstructor`)
+- Function bindings (`TextDecoderPrototype__decodeCallback`)
+- Property getters/setters (`TextDecoderPrototype__encodingGetterWrap`)
+
+## CallFrame Access
+
+The `CallFrame` object provides access to JavaScript execution context:
+
+```zig
+pub fn decode(
+    this: *TextDecoder,
+    globalObject: *JSGlobalObject,
+    callFrame: *JSC.CallFrame
+) bun.JSError!JSC.JSValue {
+    // Get arguments
+    const input = callFrame.argument(0);
+    const options = callFrame.argument(1);
+
+    // Get this value
+    const thisValue = callFrame.thisValue();
+
+    // Implementation with error handling
+    if (input.isUndefinedOrNull()) {
+        return globalObject.throw("Input cannot be null or undefined", .{});
+    }
+
+    // Return value or throw error
+    return JSC.JSValue.jsString(globalObject, "result");
+}
+```
+
+CallFrame methods include:
+
+- `argument(i)`: Get the i-th argument
+- `argumentCount()`: Get the number of arguments
+- `thisValue()`: Get the `this` value
+- `callee()`: Get the function being called
+
+## Property Caching and GC-Owned Values
+
+The `cache: true` option in property definitions enables JSC's WriteBarrier to efficiently store values:
+
+```typescript
+encoding: {
+  getter: true,
+  cache: true, // Enable caching
+}
+```
+
+### C++ Implementation
+
+In the generated C++ code, caching uses JSC's WriteBarrier:
+
+```cpp
+JSC_DEFINE_CUSTOM_GETTER(TextDecoderPrototype__encodingGetterWrap, (...)) {
+    auto& vm = JSC::getVM(lexicalGlobalObject);
+    Zig::GlobalObject *globalObject = reinterpret_cast<Zig::GlobalObject*>(lexicalGlobalObject);
+    auto throwScope = DECLARE_THROW_SCOPE(vm);
+    JSTextDecoder* thisObject = jsCast<JSTextDecoder*>(JSValue::decode(encodedThisValue));
+    JSC::EnsureStillAliveScope thisArg = JSC::EnsureStillAliveScope(thisObject);
+
+    // Check for cached value and return if present
+    if (JSValue cachedValue = thisObject->m_encoding.get())
+        return JSValue::encode(cachedValue);
+
+    // Get value from Zig implementation
+    JSC::JSValue result = JSC::JSValue::decode(
+        TextDecoderPrototype__getEncoding(thisObject->wrapped(), globalObject)
+    );
+    RETURN_IF_EXCEPTION(throwScope, {});
+
+    // Store in cache for future access
+    thisObject->m_encoding.set(vm, thisObject, result);
+    RELEASE_AND_RETURN(throwScope, JSValue::encode(result));
+}
+```
+
+### Zig Accessor Functions
+
+For each cached property, the generator creates Zig accessor functions that allow Zig code to work with these GC-owned values:
+
+```zig
+// External function declarations
+extern fn TextDecoderPrototype__encodingSetCachedValue(JSC.JSValue, *JSC.JSGlobalObject, JSC.JSValue) callconv(JSC.conv) void;
+extern fn TextDecoderPrototype__encodingGetCachedValue(JSC.JSValue) callconv(JSC.conv) JSC.JSValue;
+
+/// `TextDecoder.encoding` setter
+/// This value will be visited by the garbage collector.
+pub fn encodingSetCached(thisValue: JSC.JSValue, globalObject: *JSC.JSGlobalObject, value: JSC.JSValue) void {
+    JSC.markBinding(@src());
+    TextDecoderPrototype__encodingSetCachedValue(thisValue, globalObject, value);
+}
+
+/// `TextDecoder.encoding` getter
+/// This value will be visited by the garbage collector.
+pub fn encodingGetCached(thisValue: JSC.JSValue) ?JSC.JSValue {
+    JSC.markBinding(@src());
+    const result = TextDecoderPrototype__encodingGetCachedValue(thisValue);
+    if (result == .zero)
+        return null;
+
+    return result;
+}
+```
+
+### Benefits of GC-Owned Values
+
+This system provides several key benefits:
+
+1. **Automatic Memory Management**: The JavaScriptCore GC tracks and manages these values
+2. **Proper Garbage Collection**: The WriteBarrier ensures values are properly visited during GC
+3. **Consistent Access**: Zig code can easily get/set these cached JS values
+4. **Performance**: Cached values avoid repeated computation or serialization
+
+### Use Cases
+
+GC-owned cached values are particularly useful for:
+
+1. **Computed Properties**: Store expensive computation results
+2. **Lazily Created Objects**: Create objects only when needed, then cache them
+3. **References to Other Objects**: Store references to other JS objects that need GC tracking
+4. **Memoization**: Cache results based on input parameters
+
+The WriteBarrier mechanism ensures that any JS values stored in this way are properly tracked by the garbage collector.
+
+## Memory Management and Finalization
+
+The binding system handles memory management across the JavaScript/Zig boundary:
+
+1. **Object Creation**: JavaScript `new TextDecoder()` creates both a JS wrapper and a Zig struct
+2. **Reference Tracking**: JSC's GC tracks all JS references to the object
+3. **Finalization**: When the JS object is collected, the finalizer releases Zig resources
+
+Bun uses a consistent pattern for resource cleanup:
+
+```zig
+// Resource cleanup method - separate from finalization
+pub fn deinit(this: *TextDecoder) void {
+    // Release resources like strings
+    this._encoding.deref(); // String deref pattern
+
+    // Free any buffers
+    if (this.buffer) |buffer| {
+        bun.default_allocator.free(buffer);
+    }
+}
+
+// Called by the GC when object is collected
+pub fn finalize(this: *TextDecoder) void {
+    JSC.markBinding(@src()); // For debugging
+    this.deinit(); // Clean up resources
+    bun.default_allocator.destroy(this); // Free the object itself
+}
+```
+
+Some objects that hold references to other JS objects use `.deref()` instead:
+
+```zig
+pub fn finalize(this: *SocketAddress) void {
+    JSC.markBinding(@src());
+    this._presentation.deref(); // Release references
+    this.destroy();
+}
+```
+
+## Error Handling with JSError
+
+Bun uses `bun.JSError!JSValue` return type for proper error handling:
+
+```zig
+pub fn decode(
+    this: *TextDecoder,
+    globalObject: *JSGlobalObject,
+    callFrame: *JSC.CallFrame
+) bun.JSError!JSC.JSValue {
+    // Throwing an error
+    if (callFrame.argumentCount() < 1) {
+        return globalObject.throw("Missing required argument", .{});
+    }
+
+    // Or returning a success value
+    return JSC.JSValue.jsString(globalObject, "Success!");
+}
+```
+
+This pattern allows Zig functions to:
+
+1. Return JavaScript values on success
+2. Throw JavaScript exceptions on error
+3. Propagate errors automatically through the call stack
+
+## Type Safety and Error Handling
+
+The binding system includes robust error handling:
+
+```cpp
+// Example of type checking in generated code
+JSTextDecoder* thisObject = jsDynamicCast<JSTextDecoder*>(callFrame->thisValue());
+if (UNLIKELY(!thisObject)) {
+    scope.throwException(lexicalGlobalObject,
+        Bun::createInvalidThisError(lexicalGlobalObject, callFrame->thisValue(), "TextDecoder"_s));
+    return {};
+}
+```
+
+## Prototypal Inheritance
+
+The binding system creates proper JavaScript prototype chains:
+
+1. **Constructor**: JSTextDecoderConstructor with standard .prototype property
+2. **Prototype**: JSTextDecoderPrototype with methods and properties
+3. **Instances**: Each JSTextDecoder instance with **proto** pointing to prototype
+
+This ensures JavaScript inheritance works as expected:
+
+```cpp
+// From generated code
+void JSTextDecoderConstructor::finishCreation(VM& vm, JSC::JSGlobalObject* globalObject, JSTextDecoderPrototype* prototype)
+{
+    Base::finishCreation(vm, 0, "TextDecoder"_s, PropertyAdditionMode::WithoutStructureTransition);
+
+    // Set up the prototype chain
+    putDirectWithoutTransition(vm, vm.propertyNames->prototype, prototype, PropertyAttribute::DontEnum | PropertyAttribute::DontDelete | PropertyAttribute::ReadOnly);
+    ASSERT(inherits(info()));
+}
+```
+
+## Performance Considerations
+
+The binding system is optimized for performance:
+
+1. **Direct Pointer Access**: JavaScript objects maintain a direct pointer to Zig objects
+2. **Property Caching**: WriteBarrier caching avoids repeated native calls for stable properties
+3. **Memory Management**: JSC garbage collection integrated with Zig memory management
+4. **Type Conversion**: Fast paths for common JavaScript/Zig type conversions
+
+## Creating a New Class Binding
+
+To create a new class binding in Bun:
+
+1. **Define the class interface** in a `.classes.ts` file:
+
+   ```typescript
+   define({
+     name: "MyClass",
+     constructor: true,
+     finalize: true,
+     proto: {
+       myMethod: {
+         args: 1,
+       },
+       myProperty: {
+         getter: true,
+         cache: true,
+       },
+     },
+   });
+   ```
+
+2. **Implement the native functionality** in a `.zig` file:
+
+   ```zig
+   pub const MyClass = struct {
+       // Generated bindings
+       pub const js = JSC.Codegen.JSMyClass;
+       pub const toJS = js.toJS;
+       pub const fromJS = js.fromJS;
+       pub const fromJSDirect = js.fromJSDirect;
+
+       // State
+       value: []const u8,
+
+       pub const new = bun.TrivialNew(@This());
+
+       // Constructor
+       pub fn constructor(
+           globalObject: *JSGlobalObject,
+           callFrame: *JSC.CallFrame,
+       ) bun.JSError!*MyClass {
+           const arg = callFrame.argument(0);
+           // Implementation
+       }
+
+       // Method
+       pub fn myMethod(
+           this: *MyClass,
+           globalObject: *JSGlobalObject,
+           callFrame: *JSC.CallFrame,
+       ) bun.JSError!JSC.JSValue {
+           // Implementation
+       }
+
+       // Getter
+       pub fn getMyProperty(this: *MyClass, globalObject: *JSGlobalObject) JSC.JSValue {
+           return JSC.JSValue.jsString(globalObject, this.value);
+       }
+
+       // Resource cleanup
+       pub fn deinit(this: *MyClass) void {
+           // Clean up resources
+       }
+
+       pub fn finalize(this: *MyClass) void {
+           this.deinit();
+           bun.destroy(this);
+       }
+   };
+   ```
+
+3. **The binding generator** creates all necessary C++ and Zig glue code to connect JavaScript and Zig, including:
+   - C++ class definitions
+   - Method and property bindings
+   - Memory management utilities
+   - GC integration code
+
+## Generated Code Structure
+
+The binding generator produces several components:
+
+### 1. C++ Classes
+
+For each Zig class, the system generates:
+
+- **JS<Class>**: Main wrapper that holds a pointer to the Zig object (`JSTextDecoder`)
+- **JS<Class>Prototype**: Contains methods and properties (`JSTextDecoderPrototype`)
+- **JS<Class>Constructor**: Implementation of the JavaScript constructor (`JSTextDecoderConstructor`)
+
+### 2. C++ Methods and Properties
+
+- **Method Callbacks**: `TextDecoderPrototype__decodeCallback`
+- **Property Getters/Setters**: `TextDecoderPrototype__encodingGetterWrap`
+- **Initialization Functions**: `finishCreation` methods for setting up the class
+
+### 3. Zig Bindings
+
+- **External Function Declarations**:
+
+  ```zig
+  extern fn TextDecoderPrototype__decode(*TextDecoder, *JSC.JSGlobalObject, *JSC.CallFrame) callconv(JSC.conv) JSC.EncodedJSValue;
+  ```
+
+- **Cached Value Accessors**:
+
+  ```zig
+  pub fn encodingGetCached(thisValue: JSC.JSValue) ?JSC.JSValue { ... }
+  pub fn encodingSetCached(thisValue: JSC.JSValue, globalObject: *JSC.JSGlobalObject, value: JSC.JSValue) void { ... }
+  ```
+
+- **Constructor Helpers**:
+  ```zig
+  pub fn create(globalObject: *JSC.JSGlobalObject) bun.JSError!JSC.JSValue { ... }
+  ```
+
+### 4. GC Integration

 ### What does this PR do?
 
-<!-- **Please explain what your changes do**, example: -->
-
-<!--
-
-This adds a new flag --bail to bun test. When set, it will stop running tests after the first failure. This is useful for CI environments where you want to fail fast.
-
--->
-
-- [ ] Documentation or TypeScript types (it's okay to leave the rest blank in this case)
-- [ ] Code changes
-
 ### How did you verify your code works?
-
-<!-- **For code changes, please include automated tests**. Feel free to uncomment the line below -->
-
-<!-- I wrote automated tests -->
-
-<!-- If JavaScript/TypeScript modules or builtins changed:
-
-- [ ] I included a test for the new code, or existing tests cover it
-- [ ] I ran my tests locally and they pass (`bun-debug test test-file-name.test`)
-
--->
-
-<!-- If Zig files changed:
-
-- [ ] I checked the lifetime of memory allocated to verify it's (1) freed and (2) only freed when it should be
-- [ ] I included a test for the new code, or an existing test covers it
-- [ ] JSValue used outside outside of the stack is either wrapped in a JSC.Strong or is JSValueProtect'ed
-- [ ] I wrote TypeScript/JavaScript tests and they pass locally (`bun-debug test test-file-name.test`)
--->
-
-<!-- If new methods, getters, or setters were added to a publicly exposed class:
-
-- [ ] I added TypeScript types for the new methods, getters, or setters
--->
-
-<!-- If dependencies in tests changed:
-
-- [ ] I made sure that specific versions of dependencies are used instead of ranged or tagged versions
--->
-
-<!-- If a new builtin ESM/CJS module was added:
-
-- [ ] I updated Aliases in `module_loader.zig` to include the new module
-- [ ] I added a test that imports the module
-- [ ] I added a test that require() the module

+This is the Bun repository - an all-in-one JavaScript runtime & toolkit designed for speed, with a bundler, test runner, and Node.js-compatible package manager. It's written primarily in Zig with C++ for JavaScriptCore integration, powered by WebKit's JavaScriptCore engine.
+
+## Building and Running Bun
+
+### Build Commands
+
+- **Build debug version**: `bun bd`
+  - Creates a debug build at `./build/debug/bun-debug`
+  - Compilation takes ~5 minutes. Don't timeout, be patient.
+- **Run tests with your debug build**: `bun bd test <test-file>`
+  - **CRITICAL**: Never use `bun test` directly - it won't include your changes
+- **Run any command with debug build**: `bun bd <command>`
+
+### Other Build Variants
+
+- `bun run build:release` - Release build
+
+Address sanitizer is enabled by default in debug builds of Bun.
+
+## Testing
+
+### Running Tests
+
+- **Single test file**: `bun bd test test/js/bun/http/serve.test.ts`
+- **Fuzzy match test file**: `bun bd test http/serve.test.ts`
+- **With filter**: `bun bd test test/js/bun/http/serve.test.ts -t "should handle"`
+
+### Test Organization
+
+- `test/js/bun/` - Bun-specific API tests (http, crypto, ffi, shell, etc.)
+- `test/js/node/` - Node.js compatibility tests
+- `test/js/web/` - Web API tests (fetch, WebSocket, streams, etc.)
+- `test/cli/` - CLI command tests (install, run, test, etc.)
+- `test/regression/issue/` - Regression tests (create one per bug fix)
+- `test/bundler/` - Bundler and transpiler tests
+- `test/integration/` - End-to-end integration tests
+- `test/napi/` - N-API compatibility tests
+- `test/v8/` - V8 C++ API compatibility tests
+
+### Writing Tests
+
+Tests use Bun's Jest-compatible test runner with proper test fixtures:
+
+```typescript
+import { test, expect } from "bun:test";
+import { bunEnv, bunExe, tempDirWithFiles } from "harness";
+
+test("my feature", async () => {
+  // Create temp directory with test files
+  const dir = tempDirWithFiles("test-prefix", {
+    "index.js": `console.log("hello");`,
+  });
+
+  // Spawn Bun process
+  await using proc = Bun.spawn({
+    cmd: [bunExe(), "index.js"],
+    env: bunEnv,
+    cwd: dir,
+  });
+
+  const [stdout, stderr, exitCode] = await Promise.all([
+    new Response(proc.stdout).text(),
+    new Response(proc.stderr).text(),
+    proc.exited,
+  ]);
+
+  expect(exitCode).toBe(0);
+  expect(stdout).toBe("hello\n");
+});
+```
+
+## Code Architecture
+
+### Language Structure
+
+- **Zig code** (`src/*.zig`): Core runtime, JavaScript bindings, package manager
+- **C++ code** (`src/bun.js/bindings/*.cpp`): JavaScriptCore bindings, Web APIs
+- **TypeScript** (`src/js/`): Built-in JavaScript modules with special syntax (see JavaScript Modules section)
+- **Generated code**: Many files are auto-generated from `.classes.ts` and other sources
+
+### Core Source Organization
+
+#### Runtime Core (`src/`)
+
+- `bun.zig` - Main entry point
+- `cli.zig` - CLI command orchestration
+- `js_parser.zig`, `js_lexer.zig`, `js_printer.zig` - JavaScript parsing/printing
+- `transpiler.zig` - Wrapper around js_parser with sourcemap support
+- `resolver/` - Module resolution system
+- `allocators/` - Custom memory allocators for performance
+
+#### JavaScript Runtime (`src/bun.js/`)
+
+- `bindings/` - C++ JavaScriptCore bindings
+  - Generated classes from `.classes.ts` files
+  - Manual bindings for complex APIs
+- `api/` - Bun-specific APIs
+  - `server.zig` - HTTP server implementation
+  - `FFI.zig` - Foreign Function Interface
+  - `crypto.zig` - Cryptographic operations
+  - `glob.zig` - File pattern matching
+- `node/` - Node.js compatibility layer
+  - Module implementations (fs, path, crypto, etc.)
+  - Process and Buffer APIs
+- `webcore/` - Web API implementations
+  - `fetch.zig` - Fetch API
+  - `streams.zig` - Web Streams
+  - `Blob.zig`, `Response.zig`, `Request.zig`
+- `event_loop/` - Event loop and task management
+
+#### Build Tools & Package Manager
+
+- `src/bundler/` - JavaScript bundler
+  - Advanced tree-shaking
+  - CSS processing
+  - HTML handling
+- `src/install/` - Package manager
+  - `lockfile/` - Lockfile handling
+  - `npm.zig` - npm registry client
+  - `lifecycle_script_runner.zig` - Package scripts
+
+#### Other Key Components
+
+- `src/shell/` - Cross-platform shell implementation
+- `src/css/` - CSS parser and processor
+- `src/http/` - HTTP client implementation
+  - `websocket_client/` - WebSocket client (including deflate support)
+- `src/sql/` - SQL database integrations
+- `src/bake/` - Server-side rendering framework
+
+### JavaScript Class Implementation (C++)
+
+When implementing JavaScript classes in C++:
+
+1. Create three classes if there's a public constructor:
+
+   - `class Foo : public JSC::JSDestructibleObject` (if has C++ fields)
+   - `class FooPrototype : public JSC::JSNonFinalObject`
+   - `class FooConstructor : public JSC::InternalFunction`
+
+2. Define properties using HashTableValue arrays
+3. Add iso subspaces for classes with C++ fields
+4. Cache structures in ZigGlobalObject
+
+## Development Workflow
+
+### Code Formatting
+
+- `bun run prettier` - Format JS/TS files
+- `bun run zig-format` - Format Zig files
+- `bun run clang-format` - Format C++ files
+
+### Watching for Changes
+
+- `bun run watch` - Incremental Zig compilation with error checking
+- `bun run watch-windows` - Windows-specific watch mode
+
+### Code Generation
+
+Code generation happens automatically as part of the build process. The main scripts are:
+
+- `src/codegen/generate-classes.ts` - Generates Zig & C++ bindings from `*.classes.ts` files
+- `src/codegen/generate-jssink.ts` - Generates stream-related classes
+- `src/codegen/bundle-modules.ts` - Bundles built-in modules like `node:fs`
+- `src/codegen/bundle-functions.ts` - Bundles global functions like `ReadableStream`
+
+In development, bundled modules can be reloaded without rebuilding Zig by running `bun run build`.
+
+## JavaScript Modules (`src/js/`)
+
+Built-in JavaScript modules use special syntax and are organized as:
+
+- `node/` - Node.js compatibility modules (`node:fs`, `node:path`, etc.)
+- `bun/` - Bun-specific modules (`bun:ffi`, `bun:sqlite`, etc.)
+- `thirdparty/` - NPM modules we replace (like `ws`)
+- `internal/` - Internal modules not exposed to users
+- `builtins/` - Core JavaScript builtins (streams, console, etc.)
+
+### Special Syntax in Built-in Modules
+
+1. **`$` prefix** - Access to private properties and JSC intrinsics:
+
+   ```js
+   const arr = $Array.from(...);  // Private global
+   map.$set(...);                 // Private method
+   const arr2 = $newArrayWithSize(5); // JSC intrinsic
+   ```
+
+2. **`require()`** - Must use string literals, resolved at compile time:
+
+   ```js
+   const fs = require("fs"); // Directly loads by numeric ID
+   ```
+
+3. **Debug helpers**:
+
+   - `$debug()` - Like console.log but stripped in release builds
+   - `$assert()` - Assertions stripped in release builds
+   - `if($debug) {}` - Check if debug env var is set
+
+4. **Platform detection**: `process.platform` and `process.arch` are inlined and dead-code eliminated
+
+5. **Export syntax**: Use `export default` which gets converted to a return statement:
+   ```js
+   export default {
+     readFile,
+     writeFile,
+   };
+   ```
+
+Note: These are NOT ES modules. The preprocessor converts `$` to `@` (JSC's actual syntax) and handles the special functions.
+
+## CI
+
+Bun uses BuildKite for CI. To get the status of a PR, you can use the following command:
+
+```bash
+bun ci
+```
+
+## Important Development Notes
+
+1. **Never use `bun test` or `bun <file>` directly** - always use `bun bd test` or `bun bd <command>`. `bun bd` compiles & runs the debug build.
+2. **Use `await using`** for proper resource cleanup with Bun APIs (Bun.spawn, Bun.serve, Bun.connect, etc.)
+3. **Follow existing code style** - check neighboring files for patterns
+4. **Create regression tests** in `test/regression/issue/` when fixing bugs
+5. **Use absolute paths** - Always use absolute paths in file operations
+6. **Avoid shell commands** - Don't use `find` or `grep` in tests; use Bun's Glob and built-in tools
+7. **Memory management** - In Zig code, be careful with allocators and use defer for cleanup
+8. **Cross-platform** - Test on macOS, Linux, and Windows when making platform-specific changes
+9. **Debug builds** - Use `BUN_DEBUG_QUIET_LOGS=1` to disable debug logging, or `BUN_DEBUG_<scope>=1` to enable specific scopes
+10. **Transpiled source** - Find transpiled files in `/tmp/bun-debug-src/` for debugging
+
+## Key APIs and Features
+
+### Bun-Specific APIs
+
+- **Bun.serve()** - High-performance HTTP server
+- **Bun.spawn()** - Process spawning with better performance than Node.js
+- **Bun.file()** - Fast file I/O operations
+- **Bun.write()** - Unified API for writing to files, stdout, etc.
+- **Bun.$ (Shell)** - Cross-platform shell scripting
+- **Bun.SQLite** - Native SQLite integration
+- **Bun.FFI** - Call native libraries from JavaScript
+- **Bun.Glob** - Fast file pattern matching

+## Running debug builds
+
+The `bd` package.json script compiles and runs a debug build of Bun, only printing the output of the build process if it fails.
+
+```sh
+$ bun bd <args>
+$ bun bd test foo.test.ts
+$ bun bd ./foo.ts
+```
+
+Bun generally takes about 2.5 minutes to compile a debug build when there are Zig changes. If your development workflow is "change one line, save, rebuild", you will spend too much time waiting for the build to finish. Instead:
+
+- Batch up your changes
+- Ensure zls is running with incremental watching for LSP errors (if you use VSCode and install Zig and run `bun run build` once to download Zig, this should just work)
+- Prefer using the debugger ("CodeLLDB" in VSCode) to step through the code.
+- Use debug logs. `BUN_DEBUG_<scope>=1` will enable debug logging for the corresponding `Output.scoped(.<scope>, false)` logs. You can also set `BUN_DEBUG_QUIET_LOGS=1` to disable all debug logging that isn't explicitly enabled. To dump debug lgos into a file, `BUN_DEBUG=<path-to-file>.log`. Debug logs are aggressively removed in release builds.
+- src/js/\*\*.ts changes are pretty much instant to rebuild. C++ changes are a bit slower, but still much faster than the Zig code (Zig is one compilation unit, C++ is many).
+

This is internally how `FileSink`, `ArrayBufferSink`, `"type": "direct"` streams and other code related to streams works.
 - `./src/codegen/generate-classes.ts` -- Generates `build/debug/codegen/ZigGeneratedClasses*`, which generates Zig & C++ bindings for JavaScriptCore classes implemented in Zig. In `**/*.classes.ts` files, we define the interfaces for various classes, methods, prototypes, getters/setters etc which the code generator reads to generate boilerplate code implementing the JavaScript objects in C++ and wiring them up to Zig
+- `./src/codegen/cppbind.ts` -- Generates automatic Zig bindings for C++ functions marked with `[[ZIG_EXPORT]]` attributes.
 - `./src/codegen/bundle-modules.ts` -- Bundles built-in modules like `node:fs`, `bun:ffi` into files we can include in the final binary.

In release builds, these are embedded into the binary.
 - `./src/codegen/bundle-functions.ts` -- Bundles globally-accessible functions implemented in JavaScript/TypeScript like `ReadableStream`, `WritableStream`, and a handful more.

-## Valgrind
+## AddressSanitizer
 
-On Linux, valgrind can help find memory issues.
+[AddressSanitizer](https://en.wikipedia.org/wiki/AddressSanitizer) helps find memory issues, and is enabled by default in debug builds of Bun on Linux and macOS. This includes the Zig code and all dependencies. It makes the Zig code take about 2x longer to build, if that's stopping you from being productive you can disable it by setting `-Denable_asan=$<IF:$<BOOL:${ENABLE_ASAN}>,true,false>` to `-Denable_asan=false` in the `cmake/targets/BuildBun.cmake` file, but generally we recommend batching your changes up between builds.
 
-Keep in mind:
-
-- JavaScriptCore doesn't support valgrind. It will report spurious errors.
-- Valgrind is slow
-- Mimalloc will sometimes cause spurious errors when debug build is enabled
-
-You'll need a very recent version of Valgrind due to DWARF 5 debug symbols. You may need to manually compile Valgrind instead of using it from your Linux package manager.
-
-`--fair-sched=try` is necessary if running multithreaded code in Bun (such as the bundler). Otherwise it will hang.
+To build a release build with Address Sanitizer, run:
 
 ```bash
-$ valgrind --fair-sched=try --track-origins=yes bun-debug <args>
+$ bun run build:release:asan
 ```
 
+In CI, we run our test suite with at least one target that is built with Address Sanitizer.

-# CSS Stress Test
-
-This benchmarks bundler performance for CSS hot reloading.
-
-## Results
-
-bun is 14x faster than Next.js at hot reloading CSS.
-
-```
- bun v0.0.34
- Saving every 16ms
-
- Frame time:
- 50th percentile: 22.2ms
- 75th percentile: 23.9ms
- 90th percentile: 25.3ms
- 95th percentile: 43.6ms
- 99th percentile: 49.1ms
- Rendered frames: 922 / 1024 (90%)
-```
-
-```
- Next.js v11.1.2
- Saving every 16ms
-
- Frame time:
- 50th percentile: 312ms
- 75th percentile: 337.6ms
- 90th percentile: 387.7ms
- 95th percentile: 446.9ms
- 99th percentile: 591.7ms
- Rendered frames: 64 / 1024 (6%)
-```
-
-## How it works
-
-It times pixels instead of builds. `color-looper.zig` writes color updates and the timestamp to a css file, while simultaneously screen recording a non-headless Chromium instance. After it finishes, it OCRs the video frames and verifies the scanned timestamps against the actual data. This data measures (1) how long each update took from saving to disk up to the pixels visible on the screen and (2) what % of frames were rendered.
-
-The intent is to be as accurate as possible. Measuring times reported client-side is simpler, but lower accuracy since those times may not correspond to pixels on the screen and do not start from when the data was written to disk (at best, they measure when the filesystem watcher detected the update, but often not that either). `color-looper.zig` must run separately from `browser.js` or the results will be inaccurate.
-
-It works like this:
-
-1. `browser.js` loads either bun or Next.js and a Chromium instance opened to the correct webpage
-2. `color-looper.zig` updates [`./src/colors.css`](./src/colors.css) in a loop up to `1024` times (1024 is arbitrary), sleeping every `16`ms or `32`ms (a CLI arg you can pass it). The `var(--timestamp)` CSS variable contains the UTC timestamp with precision of milliseconds and one extra decimal point
-3. `color-looper.zig` automatically records the screen via `screencapture` (builtin on macOS) and saves it, along with a `BigUint64Array` containing all the expected timestamps. When it's done, it writes to a designated file on disk which `browser.js` picks up as the signal to close the browser.
-4. `ffmpeg` converts each frame into a black and white `.tif` file, which `tesseract` then OCRs
-5. Various cleanup scripts extract the timestamp from each of those OCR'd frames into a single file
-6. Using the OCR'd data, `./read-frames.js` calculates the 50th, 75th, 90th, 95th, and 99th percentile frame time, along with how many frames were skipped. Frame time is the metric here that matters here because that's how much time elapsed between each update. It includes the artificial sleep interval, so it will not be faster than the sleep interval.
-
-The script `run.sh` runs all the commands necessary to do this work unattended. It takes awhile though. The slow part is OCR'ing all the frames.
-
-To run this, you need:
-
-- `zig`
-- `bun-cli`
-- `node`
-- `tesseract`
-- `screencapture` (macOS builtin)
-- `ffmpeg`
-- `puppeteer` (from the package.json)
-
-You will need to run `bun bun --use next` first, with `next@11.1.2`. It will only run on macOS due to the dependencies on `screencapture`, how it detects screen resolution (so that Chromium is maximized), and how it auto-focuses Chromium (apple script)
