Hi hackers, Sorry for reviving the old thread. While digging threads related with the recent BF failure [1] I found here. And same issues were reported like [2] and [3], everything happened on the Windows platform.
Per my quick lookup of this thread, the issue could not happen if rename() works atomically. I'm not sure for Windows env, but does it mean We do not use atomic renaming on them?
