示例1: Read
func (s *Node) Read(ctx context.Context, req *fuse.ReadRequest, resp *fuse.ReadResponse) error {
k, err := s.Nd.Key()
if err != nil {
return err
}
// setup our logging event
lm := make(lgbl.DeferredMap)
lm["fs"] = "ipfs"
lm["key"] = func() interface{} { return k.B58String() }
lm["req_offset"] = req.Offset
lm["req_size"] = req.Size
defer log.EventBegin(ctx, "fuseRead", lm).Done()
r, err := uio.NewDagReader(ctx, s.Nd, s.Ipfs.DAG)
if err != nil {
return err
}
o, err := r.Seek(req.Offset, os.SEEK_SET)
lm["res_offset"] = o
if err != nil {
return err
}
buf := resp.Data[:min(req.Size, int(int64(r.Size())-req.Offset))]
n, err := io.ReadFull(r, buf)
if err != nil && err != io.EOF {
return err
}
resp.Data = resp.Data[:n]
lm["res_size"] = n
return nil // may be non-nil / not succeeded
}示例2: HandleRead
// HandleRead handles a read request assuming that data is the entire file content.
// It adjusts the amount returned in resp according to req.Offset and req.Size.
func HandleRead(req *fuse.ReadRequest, resp *fuse.ReadResponse, data []byte) {
if req.Offset >= int64(len(data)) {
data = nil
} else {
data = data[req.Offset:]
}
if len(data) > req.Size {
data = data[:req.Size]
}
n := copy(resp.Data[:req.Size], data)
resp.Data = resp.Data[:n]
}示例3: Read
func (fi *File) Read(ctx context.Context, req *fuse.ReadRequest, resp *fuse.ReadResponse) error {
_, err := fi.fi.Seek(req.Offset, os.SEEK_SET)
if err != nil {
return err
}
fisize, err := fi.fi.Size()
if err != nil {
return err
}
select {
case <-ctx.Done():
return ctx.Err()
default:
}
readsize := min(req.Size, int(fisize-req.Offset))
n, err := fi.fi.CtxReadFull(ctx, resp.Data[:readsize])
resp.Data = resp.Data[:n]
return err
}示例4: Read
func (benchFile) Read(ctx context.Context, req *fuse.ReadRequest, resp *fuse.ReadResponse) error {
resp.Data = resp.Data[:cap(resp.Data)]
return nil
}
