Thanks @zhsso. I'll test it out shortly.

Do you happen to know the difference between filepath.Clean and path.Clean?

[zhsso]

No, What's the difference?

I saw you use "file path.Clean" in https://github.com/go-fsnotify/fsnotify/blob/master/fsnotify_bsd.go#L371
and when I use Watcher.Add("./") and then mv a b, it occur an error here
https://github.com/go-fsnotify/fsnotify/blob/master/fsnotify_bsd.go#L373
because there is w.watches["./"] but not w.watches["."] in it..

I Think use filepath. Abs() must be a better way

[zhsso]

I read the source of path.Clean() filepath.Clean()
it seems they do the same thing in Linux and BSD
but filepath.Clean() deal with the PathSeparator in windows, and path.Clean() not

Is this the difference?

[nathany]

Thanks for looking into it. Sounds like we're on the right path. 😜

I'm going to tackle #34 before I merge this in and do a new release later today.
