MemoryLock

Lock used to synchronize the execution of a process using shared memory.

Extends: Lock

Description

The MemoryLock class is used to synchronize the execution of a process using shared memory.

Important points

This implementation is not suitable for synchronization of distributed processes.

Configuration parameters

options:

retry_timeout: timeout in milliseconds to retry lock acquisition. (Default: 100)

Instance methods

ReleaseLock

Releases prevously acquired lock by its key.

(c *MemoryLock) ReleaseLock(ctx context.Context, key string) error

context: IContext - (optional) a context to trace execution through call chain.
key: string - a unique lock key to release.

TryAcquireLock

Makes a single attempt to acquire a lock by its key. It returns immediately a positive or negative result.

func (c *MemoryLock) TryAcquireLock(ctx context.Context, key string, ttl int64) (bool, error)

context: IContext - (optional) a context to trace execution through call chain.
key: string - a unique lock key to acquire.
ttl: int64 - a lock timeout (time to live) in milliseconds.
returns: bool - lock result

Examples

		lock := NewMemoryLock()
		err = lock.AcquireLock(context.Background(), "123", "key1")
		if err == nil {
			 _ = lock.ReleaseLock(context.Background(), "123", "key1")
			// Processing...
		}
