A static analysis tool for Rust that detects concurrency bugs, memory bugs, and panic locations.
Lockbud is a static analysis tool for Rust that automatically detects concurrency bugs (like deadlocks), memory safety issues (like use-after-free), and potential panic locations in source code. It helps developers identify subtle, hard-to-find bugs that can lead to crashes or undefined behavior, improving the reliability and safety of Rust applications.
Rust developers and teams working on concurrent or safety-critical systems, such as blockchain clients, embedded software, or high-performance servers, who need to ensure their code is free from subtle concurrency and memory errors.
Developers choose Lockbud because it is based on rigorous academic research into real-world Rust safety issues, offers specialized detectors for critical bug patterns, and integrates easily into development workflows via Cargo, Docker, and CI/CD pipelines without requiring complex setup.
Detect concurrency and memory bugs and possible panic locations in Rust projects
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Based on studies published in TSE'24 and PLDI'20, it targets real bug patterns observed in large Rust projects, with proven bug fixes in repositories like solana and openethereum.
Can be run via cargo lockbud, Docker, or GitHub Actions, making it straightforward to incorporate into development pipelines without complex configuration, as shown in the CI examples.
Detects issues with std::sync, parking_lot, and spin primitives, covering common synchronization choices in Rust ecosystems, as listed in the caveats.
Allows filtering by crate name using the -l flag to focus on project code and reduce noise from dependencies, a feature highlighted in the announcements to manage false positives.
Only supports a limited set of synchronization primitives; custom locks or libraries like Tokio are not covered, reducing its applicability in diverse codebases.
The README admits that memory and panic detectors produce many false positives, and points-to analysis heuristics can incorrectly flag issues, especially with crates like cc.
Requires a specific Rust nightly version (e.g., nightly-2025-10-02), which can clash with project requirements and complicate toolchain management, as noted in the install instructions.
The code was implemented quickly and needs refactoring, with a todo list in issue #58, indicating potential stability or maintenance concerns that could affect reliability.
