mtime may or may not change. I based my untracked-cache series entirely on this directory mtime and did some research about it. For UNIXy filesystems on UNIXy OSes, mtime should work as you expect. FAT on Windows does not (but FAT on Linux does..). NTFS works fine according to some MS document. No idea about CIFS. But people often just do open operation of a time and this racy is not an issue. It is only an issue on the busy server side, and you can make sure you run on the right fs+OS. -- Duy -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
