Worked on stabilizing the Sway LSP session within the FuelLabs/sway repository by addressing a concurrency issue that risked deadlocks. Focused on Rust-based bug fixing, the work involved removing a redundant read-lock in session.rs, which previously caused double locking and threatened both reliability and performance. This targeted change improved session responsiveness and reduced the likelihood of deadlocks for developers using the language server. The approach emphasized careful code diagnosis, concurrency control, and performance optimization, resulting in a clean, traceable commit history. No new features were introduced during this period, with efforts concentrated on maintaining code health and developer experience.
