Andreas Kling 42da44868b LibGC: Avoid decommit worker during full sweep teardown
Heap destruction uses CollectEverything to synchronously free every live
cell. Empty blocks from that pass do not need deferred madvise work.
Registering them with the global decommit worker can start a detached
thread during process teardown. LeakSanitizer can then hang while doing
its final thread scan with log_threads enabled.

Let full sweep deallocation opt out of deferred decommit registration.
Normal incremental sweeping stays on the background worker path. The
sanitizer LibGC container and visitor tests now exit with verbose LSan
thread logging enabled.

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.
