Types

type ConnectionInfo 

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

func (ConnectionInfo) MarshalJSON added in v0.11.0 

func (info ConnectionInfo) MarshalJSON() ([]byte, error)

type Model 

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

func NewModel 

func NewModel(cfg *config.Wrapper, id protocol.DeviceID, deviceName, clientName, clientVersion string, ldb *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) Availability added in v0.10.28 

func (m *Model) Availability(folder, file string) []protocol.DeviceID

func (*Model) BringToFront added in v0.10.15 

func (m *Model) BringToFront(folder, file string)

Bump the given files priority in the job queue

func (*Model) CheckFolderHealth added in v0.11.0 

func (m *Model) CheckFolderHealth(id string) error

Returns current folder error, or nil if the folder is healthy. Updates the Invalid field on the folder configuration struct, and emits a ConfigSaved event which causes a GUI refresh.

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]interface{}

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, bool)

func (*Model) CurrentGlobalFile 

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

func (*Model) CurrentLocalVersion added in v0.10.0 

func (m *Model) CurrentLocalVersion(folder string) int64

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) FolderStatistics added in v0.10.12 

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

Returns statistics about each folder

func (*Model) GetIgnores 

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

func (*Model) GlobalDirectoryTree added in v0.10.25 

func (m *Model) GlobalDirectoryTree(folder, prefix string, levels int, dirsonly bool) map[string]interface{}

func (*Model) GlobalSize 

func (m *Model) GlobalSize(folder string) (nfiles, 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, flags uint32, options []protocol.Option)

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, flags uint32, options []protocol.Option)

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

func (*Model) LocalSize 

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

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

func (*Model) NeedFolderFiles added in v0.10.15 

func (m *Model) NeedFolderFiles(folder string, max int) ([]db.FileInfoTruncated, []db.FileInfoTruncated, []db.FileInfoTruncated)

NeedFiles returns the list of currently needed files in progress, queued, and to be queued on next puller iteration. Also takes a soft cap which is only respected when adding files from the model rather than the runner queue.

func (*Model) NeedSize 

func (m *Model) NeedSize(folder string) (nfiles 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) int64

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, hash []byte, flags uint32, options []protocol.Option) ([]byte, error)

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

func (*Model) ResetFolder added in v0.11.0 

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

func (*Model) ScanFolder added in v0.10.0

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) String added in v0.10.0 

func (m *Model) String() string

type ProgressEmitter added in v0.10.9
