There's a +[haskell library](http://hackage.haskell.org/package/hfsevents-0.1.3) +and even a [sample directory watching program](http://hackage.haskell.org/package/hobbes). +Initial tests look good... + +Using fsevents will avoid kqueue's problems with needing enough file +descriptors to open every subdirectory. kqueue is a rather poor match for +git-annex's needs, really. It does not seem to provide events for file +modifications at all, unless every *file* is individually opened. While I +dislike leaving the BSD's out, they need a better interface to be perfectly +supported by git-annex, and kqueue will still work for indirect mode +repositories. + +---- + +Got the assistant to use fsevents. It seems to work well! + +The only problem I know of is that it doesn't yet handle whole directory +renames. That should be easy to fix later. |
