Types ¶

type ListEntry ¶

type ListEntry struct {
	RID   libfossil.FslID
	UUID  string
	Date  string
	Label string
}

ListEntry describes a single node in the bisect path.

type Session ¶

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

Session manages a bisect operation, persisting state in the vvar table.

func NewSession ¶

func NewSession(db *sql.DB) *Session

NewSession creates a new bisect session backed by the given checkout DB.

func (*Session) List ¶

func (s *Session) List(currentRID libfossil.FslID) ([]ListEntry, error)

List returns all commits between good and bad, labelled appropriately.

func (*Session) MarkBad ¶

func (s *Session) MarkBad(rid libfossil.FslID) error

MarkBad records rid as a known-bad commit.

func (*Session) MarkGood ¶

func (s *Session) MarkGood(rid libfossil.FslID) error

MarkGood records rid as a known-good commit.

func (*Session) Next ¶

func (s *Session) Next() (libfossil.FslID, error)

Next returns the midpoint commit to test next. If the bisect has converged, it returns ErrBisectComplete with the bad RID embedded in the error message.

func (*Session) Reset ¶

func (s *Session) Reset()

Reset clears all bisect state from the vvar table.

func (*Session) Skip ¶

func (s *Session) Skip(rid libfossil.FslID) error

Skip marks rid as skipped (neither good nor bad).

func (*Session) Status ¶

func (s *Session) Status() StatusInfo

Status returns information about the current bisect session.

type StatusInfo ¶

type StatusInfo struct {
	Good  libfossil.FslID
	Bad   libfossil.FslID
	Log   string
	Steps int
}

StatusInfo describes the current bisect state.
