db:: (4 methods):
__construct()
acquire()
owns_lock()
release()
| __construct($config_name, \phpbb\config\config $config, \phpbb\db\driver\driver_interface $db) X-Ref |
| Creates a named released instance of the lock. You have to call acquire() to actually create the lock. param: string $config_name A config variable to be used for locking param: \phpbb\config\config $config The phpBB configuration param: \phpbb\db\driver\driver_interface $db A database connection |
| acquire() X-Ref |
| Tries to acquire the lock by updating the configuration variable in the database. As a lock may only be held by one process at a time, lock acquisition may fail if another process is holding the lock or if another process obtained the lock but never released it. Locks are forcibly released after a timeout of 1 hour. return: bool true if lock was acquired |
| owns_lock() X-Ref |
| Does this process own the lock? return: bool true if lock is owned |
| release() X-Ref |
| Releases the lock. The lock must have been previously obtained, that is, acquire() call was issued and returned true. Note: Attempting to release a lock that is already released, that is, calling release() multiple times, is harmless. return: null |
