Minor version of mutex package was released. In this version two new exceptions were introduced: MutexLockedException and MutexReleaseException. We throw them instead of less specific RuntimeException.

Additionally, the following adapter packages were released to match:

• File
• PDO MySQL
• PDO Oracle
• PDO Postgres

Fisrt version of mutex package was released. This package provides mutex implementation and allows mutual execution of concurrent processes in order to prevent "race conditions". This is achieved by using a "lock" mechanism. Each possibly concurrent processes cooperates by acquiring a lock before accessing the corresponding data.

There are multiple ways you can use the package. You can execute a callback in a synchronized mode i.e. only a single instance of the callback is executed at the same time:

/** @var \Yiisoft\Mutex\Synchronizer $synchronizer */
$newCount = $synchronizer->execute('critical', function () {
    return $counter->increase();
}, 10);
