Unlike single-master Redis lock libraries, it addresses the race condition that occurs when a Redis master crashes before replicating a lock acquisition to its slave\u2014by requiring a client to acquire the lock on a majority of independent Redis instances, it ensures safety even when individual nodes fail.\n\nThe package provides a threading.Lock-compatible API with both explicit acquire/release methods and context manager support, making it straightforward to protect critical sections in distributed systems. It also includes a RedLockFactory for efficiently reusing Redis client connections across multiple locks. However, the package has not been maintained since 2015 and targets Python 2 and early Python 3 versions, raising concerns about compatibility with current Python environments.","worth_installing":"No. While the package implements a sound algorithm and has no known vulnerabilities, it is abandoned (last release 2015-12-21) and targets Python 2 and Python 3.2\u20133.4. Compatibility with modern Python versions is unverified, and the lack of maintenance means bugs or security issues discovered in the future will not be addressed. For new projects, consider actively maintained alternatives or a more recent RedLock implementation."},"id":"redlock","links":{"html":"https://skillfed.io/packages/redlock","md":"https://skillfed.io/packages/redlock.md","pypi":"https://pypi.org/project/redlock/"},"maintenance":{"status":"abandoned"},"meta":{"latest_release":"2015-12-21","license_spdx":null,"license_treatment":"permissive","name":"redlock","python_support":"unspecified","summary":"Distributed locks with Redis"},"popularity":{"monthly_downloads":160777,"position":10651,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.2.0"}
