TODO(gabrielcorado): remove this global variable.
func NewStreamer ¶
func NewStreamer(dir string) (*events.ProtoStreamer, error)
NewStreamer creates a streamer sending uploads to disk
func SetOpenFileFunc ¶
func SetOpenFileFunc(f utils.OpenFileWithFlagsFunc)
SetOpenFileFunc sets the OpenFileWithFlagsFunc used by the package.
TODO(gabrielcorado): remove this global variable.
Types ¶
type Config ¶
type Config struct {
// Directory is a directory with files
Directory string
// OnBeforeComplete can be used to inject failures during tests
OnBeforeComplete func(ctx context.Context, upload events.StreamUpload) error
}
Config is a file uploader configuration
func (*Config) CheckAndSetDefaults ¶
CheckAndSetDefaults checks and sets default values of file handler config
type Handler ¶
type Handler struct {
// Config is a file sessions config
Config
// Entry is a file entry
*log.Entry
}
Handler uploads and downloads sessions archives by reading and writing files to directory, useful for NFS setups and tests
func NewHandler ¶
NewHandler returns new file sessions handler
func (*Handler) CompleteUpload ¶
func (h *Handler) CompleteUpload(ctx context.Context, upload events.StreamUpload, parts []events.StreamPart) error
CompleteUpload completes the upload
func (*Handler) CreateUpload ¶
func (h *Handler) CreateUpload(ctx context.Context, sessionID session.ID) (*events.StreamUpload, error)
CreateUpload creates a multipart upload
func (*Handler) Download ¶
Download downloads session recording from storage, in case of file handler reads the file from local directory
func (*Handler) GetUploadMetadata ¶
func (h *Handler) GetUploadMetadata(s session.ID) events.UploadMetadata
GetUploadMetadata gets the metadata for session upload
func (*Handler) ListParts ¶
func (h *Handler) ListParts(ctx context.Context, upload events.StreamUpload) ([]events.StreamPart, error)
ListParts lists upload parts
func (*Handler) ListUploads ¶
ListUploads lists uploads that have been initiated but not completed with earlier uploads returned first
func (*Handler) ReserveUploadPart ¶
func (h *Handler) ReserveUploadPart(ctx context.Context, upload events.StreamUpload, partNumber int64) error
ReserveUploadPart reserves an upload part.
func (*Handler) Upload ¶
func (l *Handler) Upload(ctx context.Context, sessionID session.ID, reader io.Reader) (string, error)
Upload uploads session recording to file storage, in case of file handler, writes the file to local directory
func (*Handler) UploadPart ¶
func (h *Handler) UploadPart(ctx context.Context, upload events.StreamUpload, partNumber int64, partBody io.ReadSeeker) (*events.StreamPart, error)
UploadPart uploads part
type ScanStats ¶
type ScanStats struct {
// Scanned is how many uploads have been scanned
Scanned int
// Started is how many uploads have been started
Started int
}
ScanStats provides scan statistics, used in tests
type Uploader ¶
type Uploader struct {
// contains filtered or unexported fields
}
Uploader periodically scans session records in a folder.
Once it finds the sessions it opens parallel upload streams to the streaming server.
It keeps checkpoints of the upload state and resumes the upload that have been aborted.
It marks corrupted session files to skip their processing.
func NewUploader ¶
func NewUploader(cfg UploaderConfig) (*Uploader, error)
NewUploader creates new disk based session logger
type UploaderConfig ¶
type UploaderConfig struct {
// ScanDir is data directory with the uploads
ScanDir string
// Clock is the clock replacement
Clock clockwork.Clock
// ScanPeriod is a uploader dir scan period
ScanPeriod time.Duration
// ConcurrentUploads sets up how many parallel uploads to schedule
ConcurrentUploads int
// Streamer is upstream streamer to upload events to
Streamer events.Streamer
// EventsC is an event channel used to signal events
// used in tests
EventsC chan events.UploadEvent
// Component is used for logging purposes
Component string
}
UploaderConfig sets up configuration for uploader service
func (*UploaderConfig) CheckAndSetDefaults ¶
func (cfg *UploaderConfig) CheckAndSetDefaults() error
CheckAndSetDefaults checks and sets default values of UploaderConfig
