Types

type Availability

type Availability struct {
	ID            protocol.DeviceID `json:"id"`
	FromTemporary bool              `json:"fromTemporary"`
}

type ConnectionInfo

type ConnectionInfo struct {
	protocol.Statistics
	Connected     bool
	Paused        bool
	Address       string
	ClientVersion string
	Type          string
	Crypto        string
}

func (ConnectionInfo) MarshalJSON

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

type FileError

type FileError struct {
	Path string `json:"path"`
	Err  string `json:"error"`
}

A []FileError is sent as part of an event and will be JSON serialized.

type FolderCompletion

type FolderCompletion struct {
	CompletionPct float64
	NeedBytes     int64
	NeedItems     int64
	GlobalBytes   int64
	NeedDeletes   int64
}

func (FolderCompletion) Map

func (comp FolderCompletion) Map() map[string]interface{}

Map returns the members as a map, e.g. used in api to serialize as Json.

type FolderSummaryService

type FolderSummaryService interface {
	suture.Service
	Summary(folder string) (map[string]interface{}, error)
	OnEventRequest()
}

func NewFolderSummaryService

func NewFolderSummaryService(cfg config.Wrapper, m Model, id protocol.DeviceID, evLogger events.Logger) FolderSummaryService

type Holdable

type Holdable interface {
	Holders() string
}

type Model

type Model interface {
	suture.Service

	connections.Model

	ResetFolder(folder string)
	DelayScan(folder string, next time.Duration)
	ScanFolder(folder string) error
	ScanFolders() map[string]error
	ScanFolderSubdirs(folder string, subs []string) error
	State(folder string) (string, time.Time, error)
	FolderErrors(folder string) ([]FileError, error)
	WatchError(folder string) error
	Override(folder string)
	Revert(folder string)
	BringToFront(folder, file string)
	GetIgnores(folder string) ([]string, []string, error)
	SetIgnores(folder string, content []string) error

	GetFolderVersions(folder string) (map[string][]versioner.FileVersion, error)
	RestoreFolderVersions(folder string, versions map[string]time.Time) (map[string]string, error)

	DBSnapshot(folder string) (*db.Snapshot, error)
	NeedFolderFiles(folder string, page, perpage int) ([]db.FileInfoTruncated, []db.FileInfoTruncated, []db.FileInfoTruncated)
	FolderProgressBytesCompleted(folder string) int64

	CurrentFolderFile(folder string, file string) (protocol.FileInfo, bool)
	CurrentGlobalFile(folder string, file string) (protocol.FileInfo, bool)
	Availability(folder string, file protocol.FileInfo, block protocol.BlockInfo) []Availability

	Completion(device protocol.DeviceID, folder string) FolderCompletion
	ConnectionStats() map[string]interface{}
	DeviceStatistics() (map[string]stats.DeviceStatistics, error)
	FolderStatistics() (map[string]stats.FolderStatistics, error)
	UsageReportingStats(version int, preview bool) map[string]interface{}

	StartDeadlockDetector(timeout time.Duration)
	GlobalDirectoryTree(folder, prefix string, levels int, dirsonly bool) map[string]interface{}
}

func NewModel

func NewModel(cfg config.Wrapper, id protocol.DeviceID, clientName, clientVersion string, ldb *db.Lowlevel, protectedFiles []string, evLogger events.Logger) 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.

type ProgressEmitter

type ProgressEmitter struct {
	suture.Service
	// contains filtered or unexported fields
}

func NewProgressEmitter

func NewProgressEmitter(cfg config.Wrapper, evLogger events.Logger) *ProgressEmitter

NewProgressEmitter creates a new progress emitter which emits DownloadProgress events every interval.

func (*ProgressEmitter) BytesCompleted

func (t *ProgressEmitter) BytesCompleted(folder string) (bytes int64)

BytesCompleted returns the number of bytes completed in the given folder.

func (*ProgressEmitter) CommitConfiguration

func (t *ProgressEmitter) CommitConfiguration(_, to config.Configuration) bool

CommitConfiguration implements the config.Committer interface

func (*ProgressEmitter) Deregister

func (t *ProgressEmitter) Deregister(s *sharedPullerState)

Deregister a puller which will stop broadcasting pullers state.

func (*ProgressEmitter) Register

func (t *ProgressEmitter) Register(s *sharedPullerState)

Register a puller with the emitter which will start broadcasting pullers progress.

func (*ProgressEmitter) String

func (t *ProgressEmitter) String() string

func (*ProgressEmitter) VerifyConfiguration

func (t *ProgressEmitter) VerifyConfiguration(from, to config.Configuration) error

VerifyConfiguration implements the config.Committer interface
