This chunker works in a simple way, it builds a tree out of the document so that each node either represents a chunk of real data or a chunk of data representing an branching non-leaf node of the tree. In particular each such non-leaf chunk will represent is a concatenation of the hash of its respective children. This scheme simultaneously guarantees data integrity as well as self addressing. Abstract nodes are transparent since their represented size component is strictly greater than their maximum data size, since they encode a subtree. @@ -61,17 +60,17 @@ The hashing itself does use extra copies and allocation though, since it does ne var ( errAppendOppNotSuported = errors.New("Append operation not supported") - errOperationTimedOut = errors.New("operation timed out") + errOperationTimedOut = errors.New("operation timed out") ) type TreeChunker struct { branches int64 hashFunc SwarmHasher // calculated - hashSize int64 // self.hashFunc.New().Size() - chunkSize int64 // hashSize* branches - workerCount int64 // the number of worker routines used - workerLock sync.RWMutex // lock for the worker count + hashSize int64 // self.hashFunc.New().Size() + chunkSize int64 // hashSize* branches + workerCount int64 // the number of worker routines used + workerLock sync.RWMutex // lock for the worker count } func NewTreeChunker(params *ChunkerParams) (self *TreeChunker) { @@ -124,7 +123,6 @@ func (self *TreeChunker) Split(data io.Reader, size int64, chunkC chan *Chunk, s panic("chunker must be initialised") } - jobC := make(chan *hashJob, 2*ChunkProcessors) wg := &sync.WaitGroup{} errC := make(chan error) @@ -164,7 +162,6 @@ func (self *TreeChunker) Split(data io.Reader, size int64, chunkC chan *Chunk, s close(errC) }() - defer close(quitC) select { case err := <-errC: @@ -172,7 +169,7 @@ func (self *TreeChunker) Split(data io.Reader, size int64, chunkC chan *Chunk, s return nil, err } case <-time.NewTimer(splitTimeout).C: - return nil,errOperationTimedOut + return nil, errOperationTimedOut } return key, nil |
