README

This module exposes a simple interface for acquiring a mutex lock. Currently, locking is implemented using MySQL functions (GET_LOCK and RELEASE_LOCK), but clients should not rely on this, as this is an implementation detail that is subject to change without notice.

How to use

• Create a Lock instance using factory:

  $connection = \Doctrine\DBAL\DriverManager::getConnection(['url' => $dbUrl]); 
  $factory = new \Talentry\Locking\Factory\LockFactory($connection);
  $lock = $factory->generate();
  

• Call Lock::acquire, providing the lock name.
• If the method returns true, you have acquired the lock, otherwise you failed to acquire it (possibly because another client already holds the lock).
• Do some useful work.
• Call Lock::release (again providing the lock name), to release the lock and thus make it available to other clients.
