Feb 1, 2026February 2026 monthly summary for juicedata/juicefs. Delivered Windows-specific volume management enhancements with a focus on reliability and data integrity. Implemented multi-mount support for a single volume on Windows and added a flush-on-cleanup mechanism to ensure data consistency when closing file handles, addressing close-open edge cases and reducing data loss risk in Windows deployments. Key commit reference: be024a9ad6f625c68444f699836ccdcaab706d4e (Windows: add support for mounting a volume multiple times; added flush-on-cleanup feature to enhance "close-open" consistency, (#6662)). Co-authored-by: Copilot. Overall, this work enhances stability and usability of the Windows path in JuiceFS, setting groundwork for broader Windows interoperability and more robust lifecycle management of mounted volumes.

Dec 1, 2025Month: 2025-12 Key features delivered: - Introduced GetFileInodeNotFollow: a filesystem utility that retrieves a file inode without following symbolic links, enhancing reliability of filesystem utility functions in juicedata/juicefs. Major bugs fixed: - No major bugs fixed were recorded in the provided data for this month. Overall impact and accomplishments: - Strengthened inode-level retrieval reliability and safety when dealing with symbolic links, reducing risk of unintended link traversal. This delivers concrete business value by improving correctness of filesystem tooling and setting the foundation for additional inode utilities. Technologies/skills demonstrated: - Filesystem utilities development, inode and symlink handling, and integration of new utilities into the juicedata/juicefs repository (commit b26b535fbceb84adf145082b44f36a64b842a2c1; utils: add utils.GetFileInodeNotFollow() (#6548))
