Types ¶
type SortableMutex ¶
SortableMutex is a mutex with a globally unique sequence number. The sequence number allows SortableMutexes to lock a set of mutexes in a consistent order.
func NewSortableMutex ¶
func NewSortableMutex() *SortableMutex
func (*SortableMutex) AcquireDuration ¶
func (s *SortableMutex) AcquireDuration() time.Duration
func (*SortableMutex) Lock ¶ added in v0.9.2
func (s *SortableMutex) Lock()
func (*SortableMutex) Seq ¶
func (s *SortableMutex) Seq() uint64
type SortableMutexes ¶
type SortableMutexes []*SortableMutex
SortableMutexes is a set of mutexes that can be locked in a safe order. Once Lock() is called it must not be mutated!
func (SortableMutexes) Lock ¶
func (s SortableMutexes) Lock() (start, acquired time.Time)
Lock sorts the mutexes, and then locks them in order. If any lock cannot be acquired, this will block while holding the locks with a lower sequence number. Panics if the same mutex is included more than once. Returns the time at which locking started and the time at which all locks were acquired.
func (SortableMutexes) Unlock ¶
func (s SortableMutexes) Unlock()
Unlock unlocks the sorted set of mutexes locked by a prior call to Lock().
