This channel could be closed at any time due to session invalidation, communication errors, operator intervention, etc. It is NOT safe to assume that the lock is held until Unlock() unless the Session is specifically created without any associated health checks. By default Consul sessions prefer liveness over safety and an application must be able to handle the lock being lost.

RequireConsistent bool // WaitIndex is used to enable a blocking query. Waits // until the timeout or the next index is reached WaitIndex uint64 // WaitTime is used to bound the duration of a wait. // Defaults to that of the Config, but can be overridden.

func (*Semaphore) Acquire ¶
Acquire attempts to reserve a slot in the semaphore, blocking until success, interrupted via the stopCh or an error is encountered. Providing a non-nil stopCh can be used to abort the attempt. On success, a channel is returned that represents our slot. This channel could be closed at any time due to session invalidation, communication errors, operator intervention, etc. It is NOT safe to assume that the slot is held until Release() unless the Session is specifically created without any associated health checks. By default Consul sessions prefer liveness over safety and an application must be able to handle the session being lost.
type SemaphoreOptions ¶
