It's been 37 weeks since Robert Zeh's attempt to bring inotify support to Git [1] and unless I missed some mails, no updates since. So here's another attempt with my preferred approach (can't help it, playing with your own ideas is more fun than improving other people's code) To compare to Robert's approach: - This one uses UNIX datagram socket. If I read its man page right, unix socket respects the containing directory's permission. Which means on normal repos, only the user process can access. On shared repos, multiple users can access it. This should work on Mac. Windows will need a different transport. - The daemon is dumb. It passes the paths around and that's it. lstat() is done by git. If I design it right, there's should not be any race conditions that make git miss file updates. - CE_VALID is reused to avoid mass changes (granted there's other neat ways as well). I quite like the idea of machine-controlled CE_VALID. inotify support has the potential of reducing syscalls in read_directory() as well. I wrote about using lstat() to reduce readdir() a while back, if that's implemented then inotify will fit in nicely. This is just a proof of concept. I'm sure I haven't handled all error cases very well. The first five patches show the protocol and git side's changes. The last one fills inotify in.
