[x-post from the Go newsgroup]

Go-FUSE is a fully native Go library for writing filesystems in
userspace.  It's available from

  https://github.com/hanwen/go-fuse

I've working on it steadily since the first release on Dec. 29, so
here is a status update:

* Much improved speed: now within a factor 2 of C/C++ based filesystems on
filesystem benchmarks.  For most real world applications, the
difference will be negligible.

* Supports in-process mounting of different PathFileSystems onto each
  other.

* Supports extended attributes.

* Includes more fleshed out examples:

  - ZipFS: mounting .zip archive contents

  - MultiZipFS: mounting many .zip archives on a single file system

  - UnionFS: a union mount using 1 R/W branch, and multiple R/O
    branches.

  - AutoUnionMount: automatically creates union mounts for directories
    that contain a READONLY link.

* Adds various utility classes for creating file systems easily:

  - LockingFileSystem: surrounds a non-threadsafe FS with a coarse
    grained lock.

  - TimingFileSystem: for collecting per-operation timings
    of a file system.

  - ReadOnlyFile: a FUSE file implementing just read methods.

  - DevNullFile: a FUSE file that accepts any writes and always
    returns EOF.


I'd be thrilled to get feedback on how well it works for people.

Enjoy!
