Types

type LogOperation 

type LogOperation interface {
	// Name returns the name of the task.
	Name() string

	// a count of items processed (for logging) and an error.
	ExecutePass(ctx context.Context, logID int64, info *LogOperationInfo) (int, error)
}

LogOperation defines a task that operates on a log. Examples are scheduling, signing, consistency checking or cleanup.

type LogOperationInfo 

type LogOperationInfo struct {
	// Registry provides access to Trillian storage.

	// TimeSource should be used by the LogOperation to allow mocking for tests.
	TimeSource util.TimeSource

	// RunInterval is the time between starting batches of processing.  If a
	// batch takes longer than this interval to complete, the next batch
	// will start immediately.
	RunInterval time.Duration
	// PreElectionPause is the maximum interval to wait before starting a
	// mastership election for a particular log.
	PreElectionPause time.Duration
	// MasterCheckInterval is the interval between checks that we still
	// hold mastership for a log.
	MasterCheckInterval time.Duration
	// MasterHoldInterval is the minimum interval to hold mastership for.
	MasterHoldInterval time.Duration
	// ResignOdds gives the chance of resigning mastership after each
	// check interval, as the N for 1-in-N.
