Aliaksandr Kalenik 4ea4d63008 Everywhere: Replace Unix socket IPC transport with Mach ports on macOS
On macOS, use Mach port messaging instead of Unix domain sockets for
all IPC transport. This makes the transport capable of carrying Mach
port rights as message attachments, which is a prerequisite for sending
IOSurface handles over the main IPC channel (currently sent via a
separate out-of-band path). It also avoids the need for the FD
acknowledgement protocol that TransportSocket requires, since Mach port
right transfers are atomic in the kernel.

Three connection establishment patterns:

- Spawned helper processes (WebContent, RequestServer, etc.) use the
  existing MachPortServer: the child sends its task port with a reply
  port, and the parent responds with a pre-created port pair.

- Socket-bootstrapped connections (WebDriver, BrowserProcess) exchange
  Mach port names over the socket, then drop the socket.

- Pre-created pairs for IPC tests and in-message transport transfer.

Attachment on macOS now wraps a MachPort instead of a file descriptor,
converting between the two via fileport_makeport()/fileport_makefd().

The LibIPC socket transport tests are disabled on macOS since they are
socket-specific.

Ladybird

Ladybird is a truly independent web browser, using a novel engine based on web standards.

Important

Ladybird is in a pre-alpha state, and only suitable for use by developers

Features

We aim to build a complete, usable browser for the modern web.

Ladybird uses a multi-process architecture with a main UI process, several WebContent renderer processes, an ImageDecoder process, and a RequestServer process.

Image decoding and network connections are done out of process to be more robust against malicious content. Each tab has its own renderer process, which is sandboxed from the rest of the system.

At the moment, many core library support components are inherited from SerenityOS:

  • LibWeb: Web rendering engine
  • LibJS: JavaScript engine
  • LibWasm: WebAssembly implementation
  • LibCrypto/LibTLS: Cryptography primitives and Transport Layer Security
  • LibHTTP: HTTP/1.1 client
  • LibGfx: 2D Graphics Library, Image Decoding and Rendering
  • LibUnicode: Unicode and locale support
  • LibMedia: Audio and video playback
  • LibCore: Event loop, OS abstraction layer
  • LibIPC: Inter-process communication

How do I build and run this?

See build instructions for information on how to build Ladybird.

Ladybird runs on Linux, macOS, Windows (with WSL2), and many other *Nixes.

How do I read the documentation?

Code-related documentation can be found in the documentation folder.
