Sentry` is a platform for tracking errors and monitoring applications, and it's interested in debugging `WebAssembly` (WASM) code. WASM is a binary format that allows executing code compiled from languages like C, C++, Rust, or others in the browser at near-native speeds. However, debugging with WASM poses several challenges due to its stack-based nature, which makes traditional debugging techniques less effective. The main issue is that WASM functions are not "addressable" in the same memory space as native code, making it difficult to unwind the stack and obtain reliable function names, line numbers, and file names. To address this, Sentry uses a workaround involving JavaScript exceptions and DWARF (Debugging With Attributed Record Formats), but there are limitations and challenges with these approaches, including issues with DWARF splitting and debug IDs. Despite these challenges, Sentry is exploring ways to improve WASM debugging and has proposed an extension for debug IDs.
