Jul 1, 2025July 2025 monthly summary for rclone/rclone focusing on Bisync reliability improvements, code maintainability, and test robustness. Key outcomes: 1) Bisync: Safe concurrent runs — fixed concurrency errors by deglobalizing global variables, enabling safe concurrent bisync runs from a single rclone instance; added TestBisyncConcurrent to verify the fix. Notable commits: 9073d173134fe127ecc7da55869eb29bf34e8b30 (bisync: deglobalize to fix concurrent runs via rc - fixes #8675). 2) Bisync: Code cleanup and simplified function signatures — reduced unused parameters and simplified code paths to improve maintainability; commit d91cbb2626bf0c6cbec52c998a146d46d4b4ed0e (bisync: remove unused parameters). 3) Sync test robustness: test correctness fixes — corrected testLoggerVsLsf to use the right filesystem for server-side tests and fixed ModTime handling when backends advertise ModTimeNotSupported but return a modtime; commits: c1ebfb7e0440648428ea8304c4aedf87bb24db20 (sync: fix testLoggerVsLsf checking wrong fs) and 0eb7ee2e168a26621a592ac350099a7806ab9a13 (sync: fix testLoggerVsLsf when backend only reads modtime).

May 1, 2025May 2025 (2025-05) highlights feature work delivering a Path name transformation framework and foundational refactoring to enable future source-side transformations for rclone/rclone. The changes establish scalable path customization across sync, copy, and move operations via a new transform library and a --name-transform flag, and refactor the march utility to separate source and destination key generation (srcKey/dstKey) for easier extension.
