NFS-safe File Locking

JSON →
library 9.0.0 ·python
verified Jun 28, 2026

The flufl.lock library provides an NFS-safe, file-based locking algorithm for POSIX and Windows systems, heavily influenced by the GNU/Linux open(2) manpage's O_EXCL option. It aims to prevent race conditions on NFS file systems by using atomic file operations with robust timeouts and lock-breaking capabilities. Currently at version 9.0.0, the library is under active development with regular updates and maintenance releases.
