Package fuse enables writing FUSE file systems on Linux, OS X, and FreeBSD. On OS X, it requires OSXFUSE (http://osxfuse.github.com/). There are two approaches to writing a FUSE file system. The first is to speak the low-level message protocol, reading from a Conn using ReadRequest and writing using the various Respond methods. This approach is closest to the actual interaction with the kernel and can be the simplest one in contexts such as protocol translators. Servers of synthesized file systems tend to share common bookkeeping abstracted away by the second approach, which is to call fs.Serve to serve the FUSE protocol using an implementation of the service methods in the interfaces FS* (file system), Node* (file or directory), and Handle* (opened file or directory). There are a daunting number of such methods that can be written, but few are required. The specific methods are described in the documentation for those interfaces. The hellofs subdirectory contains a simple illustration of the fs.Serve approach. The required and optional methods for the FS, Node, and Handle interfaces have the general form where Op is the name of a FUSE operation. Op reads request parameters from req and writes results to resp. An operation whose only result is the error result omits the resp parameter. Multiple goroutines may call service methods simultaneously; the methods being called are responsible for appropriate synchronization. In some file systems, some operations may take an undetermined amount of time. For example, a Read waiting for a network message or a matching Write might wait indefinitely. If the request is cancelled and no longer needed, the package will close intr, a chan struct{}. Blocking operations should select on a receive from intr and attempt to abort the operation early if the receive succeeds (meaning the channel is closed). To indicate that the operation failed because it was aborted, return fuse.EINTR. If an operation does not block for an indefinite amount of time, the intr parameter can be ignored. All requests types embed a Header, meaning that the method can inspect req.Pid, req.Uid, and req.Gid as necessary to implement permission checking. Alternately, XXX. Behavior and metadata of the mounted file system can be changed by passing MountOption values to Mount.
