The source code position cache was moved from a line based approach to a "chunk"-based approach to improve performance on large, minified JavaScript files with few lines, but this has had an adverse effect on _multi-line_ source files. Reintroduce some of the old behaviour by caching lines again, with some added sanity limits to avoid caching empty/overly small lines. Source code positions in files with few lines will still be cached less often, since minified JavaScript files can be assumed to be unusually large, and since stack traces for minified JavaScript are less useful as well. On WPT tests with large JavaScript dependencies like `css/css-masking/animations/clip-interpolation.html` this reduces the amount of time spent in `SourceCode::range_from_offsets` by as much as 99.98%, for the small small price of 80KB extra memory usage. |

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.
