Types

type ConnectionInfo 

type ConnectionInfo struct {
	protocol.Statistics
	Address       string
	ClientVersion string
}

type Model 

type Model struct {
	// contains filtered or unexported fields
}

func NewModel 

func NewModel(cfg *config.ConfigWrapper, deviceName, clientName, clientVersion string, db *leveldb.DB) *Model

NewModel creates and starts a new model. The model starts in read-only mode, where it sends index information to connected peers and responds to requests for file data without altering the local folder in any way.

func (*Model) AddConnection 

func (m *Model) AddConnection(rawConn io.Closer, protoConn protocol.Connection)

AddConnection adds a new peer connection to the model. An initial index will be sent to the connected peer, thereafter index updates whenever the local folder changes.

func (*Model) AddFolder added in v0.10.0 

func (m *Model) AddFolder(cfg config.FolderConfiguration)

func (*Model) Close 

func (m *Model) Close(device protocol.DeviceID, err error)

Close removes the peer from the model and closes the underlying connection if possible. Implements the protocol.Model interface.

func (*Model) ClusterConfig 

func (m *Model) ClusterConfig(deviceID protocol.DeviceID, cm protocol.ClusterConfigMessage)

func (*Model) Completion 

func (m *Model) Completion(device protocol.DeviceID, folder string) float64

Returns the completion status, in percent, for the given device and folder.

func (*Model) ConnectedTo 

func (m *Model) ConnectedTo(deviceID protocol.DeviceID) bool

ConnectedTo returns true if we are connected to the named device.

func (*Model) ConnectionStats 

func (m *Model) ConnectionStats() map[string]ConnectionInfo

ConnectionStats returns a map with connection statistics for each connected device.

func (*Model) CurrentFolderFile added in v0.10.0 

func (m *Model) CurrentFolderFile(folder string, file string) protocol.FileInfo

func (*Model) CurrentGlobalFile 

func (m *Model) CurrentGlobalFile(folder string, file string) protocol.FileInfo

func (*Model) CurrentLocalVersion added in v0.10.0 

func (m *Model) CurrentLocalVersion(folder string) uint64

CurrentLocalVersion returns the change version for the given folder. This is guaranteed to increment if the contents of the local folder has changed.

func (*Model) DeviceStatistics added in v0.10.0 

func (m *Model) DeviceStatistics() map[string]stats.DeviceStatistics

Returns statistics about each device

func (*Model) GetIgnores 

func (m *Model) GetIgnores(folder string) ([]string, []string, error)

func (*Model) GlobalSize 

func (m *Model) GlobalSize(folder string) (files, deleted int, bytes int64)

GlobalSize returns the number of files, deleted files and total bytes for all files in the global model.

func (*Model) Index 

func (m *Model) Index(deviceID protocol.DeviceID, folder string, fs []protocol.FileInfo)

Index is called when a new device is connected and we receive their full index. Implements the protocol.Model interface.

func (*Model) IndexUpdate 

func (m *Model) IndexUpdate(deviceID protocol.DeviceID, folder string, fs []protocol.FileInfo)

IndexUpdate is called for incremental updates to connected devices' indexes. Implements the protocol.Model interface.

func (*Model) LocalSize 

func (m *Model) LocalSize(folder string) (files, deleted int, bytes int64)

LocalSize returns the number of files, deleted files and total bytes for all files in the local folder.

func (*Model) NeedFolderFilesLimited added in v0.10.0 

func (m *Model) NeedFolderFilesLimited(folder string, maxFiles int) []protocol.FileInfoTruncated

NeedFiles returns the list of currently needed files, stopping at maxFiles files. Limit <= 0 is ignored.

func (*Model) NeedSize 

func (m *Model) NeedSize(folder string) (files int, bytes int64)

NeedSize returns the number and total size of currently needed files.

func (*Model) Override 

func (m *Model) Override(folder string)

func (*Model) RemoteLocalVersion added in v0.10.0 

func (m *Model) RemoteLocalVersion(folder string) uint64

RemoteLocalVersion returns the change version for the given folder, as sent by remote peers. This is guaranteed to increment if the contents of the remote or global folder has changed.

func (*Model) ReplaceLocal 

func (m *Model) ReplaceLocal(folder string, fs []protocol.FileInfo)

ReplaceLocal replaces the local folder index with the given list of files.

func (*Model) Request 

func (m *Model) Request(deviceID protocol.DeviceID, folder, name string, offset int64, size int) ([]byte, error)

Request returns the specified data segment by reading it from local disk. Implements the protocol.Model interface.

func (*Model) ScanFolder added in v0.10.0 

func (m *Model) ScanFolder(folder string) error

func (*Model) ScanFolderSub added in v0.10.0 

func (m *Model) ScanFolderSub(folder, sub string) error

func (*Model) ScanFolders added in v0.10.0 

func (m *Model) ScanFolders()

func (m *Model) SetIgnores(folder string, content []string) error

func (*Model) StartFolderRO added in v0.10.0 

func (m *Model) StartFolderRO(folder string)

StartRO starts read only processing on the current model. When in read only mode the model will announce files to the cluster but not pull in any external changes.

func (*Model) StartFolderRW added in v0.10.0 

func (m *Model) StartFolderRW(folder string)

StartRW starts read/write processing on the current model. When in read/write mode the model will attempt to keep in sync with the cluster by pulling needed files from peer devices.

func (*Model) State 

func (m *Model) State(folder string) (string, time.Time)

func (*Model) String added in v0.10.0 

func (m *Model) String() string
