+## CI
+
+How does CI work?
+
+### Building
+
+Bun is built on macOS, Linux, and Windows. The process is split into the following steps, the first 3 of which are able to run in parallel:
+
+#### 1. `build-deps`
+
+Builds the static libaries in `src/deps` and outputs a directory: `build/bun-deps`.
+
+- on Windows, this runs the script: [`scripts/all-dependencies.ps1`](scripts/all-dependencies.ps1)
+- on macOS and Linux, this runs the script: [`scripts/all-dependencies.sh`](scripts/all-dependencies.sh)
+
+#### 2. `build-zig`
+
+Builds the Zig object file: `build/bun-zig.o`. Since `zig build` supports cross-compiling, this step is run on macOS aarch64 since we have observed it to be the fastest.
+
+- on macOS and Linux, this runs the script: [`scripts/build-bun-zig.sh`](scripts/build-bun-zig.sh)
+
+#### 3. `build-cpp`
+
+Builds the C++ object file: `build/bun-cpp-objects.a`.
+
+- on Windows, this runs the script: [`scripts/build-bun-cpp.ps1`](scripts/build-bun-cpp.ps1)
+- on macOS and Linux, this runs the script: [`scripts/build-bun-cpp.sh`](scripts/build-bun-cpp.sh)
+
+#### 4. `link` / `build-bun`
+
+After the `build-deps`, `build-zig`, and `build-cpp` steps have completed, this step links the Zig object file and C++ object file into a single binary: `bun-<os>-<arch>.zip`.
+
+- on Windows, this runs the script: [`scripts/buildkite-link-bun.ps1`](scripts/buildkite-link-bun.ps1)
+- on macOS and Linux, this runs the script: [`scripts/buildkite-link-bun.sh`](scripts/buildkite-link-bun.sh)
+
+To speed up the build, thare are two options:
+
+- `--fast`: This disables the LTO (link-time optimization) step.
+- without `--fast`: This runs the LTO step, which is the default. The binaries that are release to Github are always built with LTO.
+
+### Testing
+
+### FAQ
+
+> How do I add a new CI agent?
+
+> How do I add/modify system dependencies?
+
+> How do I SSH into a CI agent?
+
+### Known issues
+
+These are things that we know about, but haven't fixed or optimized yet.
+
+- There is no `scripts/build-bun-zig.ps1` for Windows.
+
+- The `build-deps` step does not cache in CI, so it re-builds each time (though it does use ccache). It attempts to check the `BUN_DEPS_CACHE_DIR` environment variable, but for some reason it doesn't work.
+
+- Windows and Linux machines sometimes take up to 1-2 minutes to start tests. This is because robobun is listening for when the job is scheduled to provision the VM. Instead, it can start provisioning during the link step, or keep a pool of idle VMs around (but it's unclear how more expensive this is).
+
+- There are a limited number of macOS VMs. This is because they are expensive and manually provisioned, mostly through MacStadium. If wait times are too long we can just provision more, or buy some.
+
+- To prevent idle machines, robobun periodically checks for idle machines and terminates them. Before doing this, it checks to see if the machine is connected as an agent to Buildkite. However, sometimes the machine picks up a job in-between this time, and the job is terminated.

+TL;DR: Ubuntu 22.04 is suggested.
+Bun currently requires `glibc >=2.32` in development which means if you're on Ubuntu 20.04 (glibc == 2.31), you may likely meet `error: undefined symbol: __libc_single_threaded `. You need to take extra configurations. Also, according to this [issue](https://github.com/llvm/llvm-project/issues/97314), LLVM 16 is no longer maintained on Ubuntu 24.04 (noble). And instead, you might want `brew` to install LLVM 16 for your Ubuntu 24.04.

-> (1) If you statically link against an LGPL’d library, you must also provide your application in an object (not necessarily source) format, so that a user has the opportunity to modify the library and relink the application.
-
-You can find the patched version of WebKit used by Bun here: <https://github.com/oven-sh/webkit>. If you would like to relink Bun with changes:
-
-- `git submodule update --init --recursive`
-- `make jsc`
-- `zig build`
-
-This compiles JavaScriptCore, compiles Bun’s `.cpp` bindings for JavaScriptCore (which are the object files using JavaScriptCore) and outputs a new `bun` binary with your changes.

+Bun implements the WHATWG `fetch` standard, with some extensions to meet the needs of server-side JavaScript.
+
+Bun also implements `node:http`, but `fetch` is generally recommended instead.
+
+## Sending an HTTP request
+
+To send an HTTP request, use `fetch`
+
+```ts
+const response = await fetch("http://example.com");
+
+console.log(response.status); // => 200
+
+const text = await response.text(); // or response.json(), response.formData(), etc.
+```
+
+`fetch` also works with HTTPS URLs.
+
+```ts
+const response = await fetch("https://example.com");
+```
+
+You can also pass `fetch` a [`Request`](https://developer.mozilla.org/en-US/docs/Web/API/Request) object.
+
+```ts
+const request = new Request("http://example.com", {
+  method: "POST",
+  body: "Hello, world!",
+});
+
+const response = await fetch(request);
+```
+
+### Sending a POST request
+
+To send a POST request, pass an object with the `method` property set to `"POST"`.
+
+```ts
+const response = await fetch("http://example.com", {
+  method: "POST",
+  body: "Hello, world!",
+});
+```
+
+`body` can be a string, a `FormData` object, an `ArrayBuffer`, a `Blob`, and more. See the [MDN documentation](https://developer.mozilla.org/en-US/docs/Web/API/Body/body) for more information.
+
+### Proxying requests
+
+To proxy a request, pass an object with the `proxy` property set to a URL.
+
+```ts
+const response = await fetch("http://example.com", {
+  proxy: "http://proxy.com",
+});
+```
+
+### Custom headers
+
+To set custom headers, pass an object with the `headers` property set to an object.
+
+```ts
+const response = await fetch("http://example.com", {
+  headers: {
+    "X-Custom-Header": "value",
+  },
+});
+```
+
+You can also set headers using the [Headers](https://developer.mozilla.org/en-US/docs/Web/API/Headers) object.
+
+```ts
+const headers = new Headers();
+headers.append("X-Custom-Header", "value");
+
+const response = await fetch("http://example.com", {
+  headers,
+});
+```
+
+### Response bodies
+
+To read the response body, use one of the following methods:
+
+- `response.text(): Promise<string>`: Returns a promise that resolves with the response body as a string.
+- `response.json(): Promise<any>`: Returns a promise that resolves with the response body as a JSON object.
+- `response.formData(): Promise<FormData>`: Returns a promise that resolves with the response body as a `FormData` object.
+- `response.bytes(): Promise<Uint8Array>`: Returns a promise that resolves with the response body as a `Uint8Array`.
+- `response.arrayBuffer(): Promise<ArrayBuffer>`: Returns a promise that resolves with the response body as an `ArrayBuffer`.
+- `response.blob(): Promise<Blob>`: Returns a promise that resolves with the response body as a `Blob`.
+
+#### Streaming response bodies
+
+You can use async iterators to stream the response body.
+
+```ts
+const response = await fetch("http://example.com");
+
+for await (const chunk of response.body) {
+  console.log(chunk);
+}
+```
+
+You can also more directly access the `ReadableStream` object.
+
+```ts
+const response = await fetch("http://example.com");
+
+const stream = response.body;
+
+const reader = stream.getReader();
+const { value, done } = await reader.read();
+```
+
+### Fetching a URL with a timeout
+
+To fetch a URL with a timeout, use `AbortSignal.timeout`:
+
+```ts
+const response = await fetch("http://example.com", {
+  signal: AbortSignal.timeout(1000),
+});
+```
+
+#### Canceling a request
+
+To cancel a request, use an `AbortController`:
+
+```ts
+const controller = new AbortController();
+
+const response = await fetch("http://example.com", {
+  signal: controller.signal,
+});
+
+controller.abort();
+```
+
+### Unix domain sockets
+
+To fetch a URL using a Unix domain socket, use the `unix: string` option:
+
+```ts
+const response = await fetch("https://hostname/a/path", {
+  unix: "/var/run/path/to/unix.sock",
+  method: "POST",
+  body: JSON.stringify({ message: "Hello from Bun!" }),
+  headers: {
+    "Content-Type": "application/json",
+  },
+});
+```
+
+### TLS
+
+To use a client certificate, use the `tls` option:
+
+```ts
+await fetch("https://example.com", {
+  tls: {
+    key: Bun.file("/path/to/key.pem"),
+    cert: Bun.file("/path/to/cert.pem"),
+    // ca: [Bun.file("/path/to/ca.pem")],
+  },
+});
+```
+
+#### Custom TLS Validation
+
+To customize the TLS validation, use the `checkServerIdentity` option in `tls`
+
+```ts
+await fetch("https://example.com", {
+  tls: {
+    checkServerIdentity: (hostname, peerCertificate) => {
+      // Return an error if the certificate is invalid
+    },
+  },
+});
+```
+
+This is similar to how it works in Node's `net` module.
+
+## Debugging
+
+To help with debugging, you can pass `verbose: true` to `fetch`:
+
+```ts
+const response = await fetch("http://example.com", {
+  verbose: true,
+});
+```
+
+This will print the request and response headers to your terminal:
+
+```sh
+[fetch] > HTTP/1.1 GET http://example.com/
+[fetch] > Connection: keep-alive
+[fetch] > User-Agent: Bun/1.1.21
+[fetch] > Accept: */*
+[fetch] > Host: example.com
+[fetch] > Accept-Encoding: gzip, deflate, br
+
+[fetch] < 200 OK
+[fetch] < Content-Encoding: gzip
+[fetch] < Age: 201555
+[fetch] < Cache-Control: max-age=604800
+[fetch] < Content-Type: text/html; charset=UTF-8
+[fetch] < Date: Sun, 21 Jul 2024 02:41:14 GMT
+[fetch] < Etag: "3147526947+gzip"
+[fetch] < Expires: Sun, 28 Jul 2024 02:41:14 GMT
+[fetch] < Last-Modified: Thu, 17 Oct 2019 07:18:26 GMT
+[fetch] < Server: ECAcc (sac/254F)
+[fetch] < Vary: Accept-Encoding
+[fetch] < X-Cache: HIT
+[fetch] < Content-Length: 648
+```
+
+Note: `verbose: boolean` is not part of the Web standard `fetch` API and is specific to Bun.
+
+## Performance
+
+Before an HTTP request can be sent, the DNS lookup must be performed. This can take a significant amount of time, especially if the DNS server is slow or the network connection is poor.
+
+After the DNS lookup, the TCP socket must be connected and the TLS handshake might need to be performed. This can also take a significant amount of time.
+
+After the request completes, consuming the response body can also take a significant amount of time and memory.
+
+At every step of the way, Bun provides APIs to help you optimize the performance of your application.
+
+### DNS prefetching
+
+To prefetch a DNS entry, you can use the `dns.prefetch` API. This API is useful when you know you'll need to connect to a host soon and want to avoid the initial DNS lookup.
+
+```ts
+import { dns } from "bun";
+
+dns.prefetch("bun.sh", 443);
+```
+
+#### DNS caching
+
+By default, Bun caches and deduplicates DNS queries in-memory for up to 30 seconds. You can see the cache stats by calling `dns.getCacheStats()`:
+
+To learn more about DNS caching in Bun, see the [DNS caching](/docs/api/dns) documentation.
+
+### Preconnect to a host
+
+To preconnect to a host, you can use the `fetch.preconnect` API. This API is useful when you know you'll need to connect to a host soon and want to start the initial DNS lookup, TCP socket connection, and TLS handshake early.
+
+```ts
+import { fetch } from "bun";
+
+fetch.preconnect("https://bun.sh");
+```
+
+Note: calling `fetch` immediately after `fetch.preconnect` will not make your request faster. Preconnecting only helps if you know you'll need to connect to a host soon, but you're not ready to make the request yet.
+
+#### Preconnect at startup
+
+To preconnect to a host at startup, you can pass `--fetch-preconnect`:
+
+```sh
+$ bun --fetch-preconnect https://bun.sh ./my-script.ts
+```
+
+This is sort of like `<link rel="preconnect">` in HTML.
+
+This feature is not implemented on Windows yet. If you're interested in using this feature on Windows, please file an issue and we can implement support for it on Windows.
+
+### Connection pooling & HTTP keep-alive
+
+Bun automatically reuses connections to the same host. This is known as connection pooling. This can significantly reduce the time it takes to establish a connection. You don't need to do anything to enable this; it's automatic.
+
+#### Simultaneous connection limit
+
+By default, Bun limits the maximum number of simultaneous `fetch` requests to 256. We do this for several reasons:
+
+- It improves overall system stability. Operating systems have an upper limit on the number of simultaneous open TCP sockets, usually in the low thousands. Nearing this limit causes your entire computer to behave strangely. Applications hang and crash.
+- It encourages HTTP Keep-Alive connection reuse. For short-lived HTTP requests, the slowest step is often the initial connection setup. Reusing connections can save a lot of time.
+
+When the limit is exceeded, the requests are queued and sent as soon as the next request ends.
+
+You can increase the maximum number of simultaneous connections via the `BUN_CONFIG_MAX_HTTP_REQUESTS` environment variable:
+
+```sh
+$ BUN_CONFIG_MAX_HTTP_REQUESTS=512 bun ./my-script.ts
+```
+
+The max value for this limit is currently set to 65,336. The maximum port number is 65,535, so it's quite difficult for any one computer to exceed this limit.
+
+### Response buffering
+
+Bun goes to great lengths to optimize the performance of reading the response body. The fastest way to read the response body is to use one of these methods:
+
+- `response.text(): Promise<string>`
+- `response.json(): Promise<any>`
+- `response.formData(): Promise<FormData>`
+- `response.bytes(): Promise<Uint8Array>`
+- `response.arrayBuffer(): Promise<ArrayBuffer>`
+- `response.blob(): Promise<Blob>`
+
+You can also use `Bun.write` to write the response body to a file on disk:
+
+```ts
+import { write } from "bun";
+
+await write("output.txt", response);
+```

docs/test/mocks.md

@@ -196,3 +196,41 @@ As of Bun v1.0.19, Bun automatically resolves the `specifier` argument to `mock.
 After resolution, the mocked module is stored in the ES Module registry **and** the CommonJS require cache. This means that you can use `import` and `require` interchangeably for mocked modules.
 
 The callback function is called lazily, only if the module is imported or required. This means that you can use `mock.module()` to mock modules that don't exist yet, and it means that you can use `mock.module()` to mock modules that are imported by other modules.
+
+## Restore all function mocks to their original values with `mock.restore()`
+
+Instead of manually restoring each mock individually with `mockFn.mockRestore()`, restore all mocks with one command by calling `mock.restore()`. Doing so does not reset the value of modules overridden with `mock.module()`.
+
+Using `mock.restore()` can reduce the amount of code in your tests by adding it to `afterEach` blocks in each test file or even in your [test preload code](https://bun.sh/docs/runtime/bunfig#test-preload).
