------- Additional comments from [EMAIL PROTECTED] Wed Sep 28 23:20:29 -0700 2005 ------- @sb: hmm, strange: I thought I'd replied to your latest comments, but there is nothing in the issue :(. So here we go again: - "Correct me if I am wrong, but as far as I know, locks are removed as soon as any file descriptor on the same file is closed, and that is a general design "feature" of fcntl(F_SETLK), irrespective of NFS." I don't remember the details (so you are probably right on them). However, the result is the same - we actively need to make sure that a file get's opened only once at a time. - "Compare-and-overwrite would have to be an atomic operation then, which it is not. Thus, your proposed approach #6 IMO gives a false sense of security." The point I was trying to make is that the feedback IMHO needs to arise at the time the user _saves_ the document, not when (s)he opens it (which potentially could be days earlier). To make this more atomic, the algorithm could work like: save operation: try locking the file and warn if that fails (cancel y/n) - compare modification time and warn if that fails (cancel y/n) - overwrite the document. I could even imagine that the modification time gets checked each time the window contain the visualization of the document receives the focus. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
