在Golang中使用go-fuse包

Question

Hello I'm about to port my two almost working simple fuse filesystems from bazillion fuse to go-fuse. go-fuse api seems more complex. The question is:

1. In NewServer(), which RawFileSystem to use?
2. How to implement callbacks for read, readdir etc.?
3. Where to use WaitMount()?
4. What are DeleteNotify(), EntryNotify()?

Answer 1

ok i found the solutions

1. make a struct that contains nodefs.Node:

    type my_root struct {nodefs.Node}

initialize it

    my = &my_root{Node: nodefs.NewDefaultNode()}

make a connection and a raw filesystem

    con := nodefs.NewFileSystemConnector(my, nil)
    raw := fuse.NewRawFileSystem(con.RawFS())

finally, fire up the fuse fs

    server, err := fuse.NewServer(raw, f.dir, optz)

1. like this:

   func (my_root) OpenDir(context *fuse.Context) ([]fuse.DirEntry, fuse.Status) {}
   func (my_root) Lookup(out *fuse.Attr, name string, context *fuse.Context) (node *nodefs.Inode, code fuse.Status)
   

2. after step 1, like this:

   server.WaitMount()
   

3. i didn't need this.
