AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

Locket provides file-based locks for inter-process synchronization on Linux and Windows, allowing multiple processes to coordinate access to shared resources using a common lock file path.

Installation is straightforward with no runtime dependencies. However, the package is marked abandoned with its last commit in February 2023 and no release for over two years, raising concerns about maintenance and responsiveness to issues.

BSD-2-Clause is a permissive open-source license that allows commercial and private use with minimal restrictions, requiring only preservation of copyright and license notices.

pip install locket

import locket

with locket.lock_file("/path/to/lock"):
    # critical section
    pass

Verdict: Locket is a lightweight, dependency-free file-locking utility suitable for simple inter-process coordination scenarios. Its permissive license and broad Python version support (2.7 through 3.10) make it accessible, but the abandoned maintenance status—no releases since April 2022—means it will not receive bug fixes or security updates. Use only if your locking needs are stable and unlikely to require future maintenance.

Needs verification

• Whether the package has known issues or edge cases that emerged after the last release in 2022
• Whether fork behavior (documented as undefined) causes problems in real-world concurrent scenarios
• Whether there are more actively maintained alternatives with similar functionality
