 * Support run code async. To use it, you just config it to your application components in configure file:
25
 *
26
 * ```php
27
 * 'components' => [
28
 *      'async' => 'vxm\async\Async'
29
 * ]
30
 *
31
 * ```
32
 *
33
 * And after that you can run an async code:
34
 *
35
 * ```php
36
 *
37
 * Yii::$app->async->run(function () {
38
 *
39
 *      sleep(5);
40
 * });
41
 *
42
 * ```
43
 *
44
 * If you want to wait until task done, you just to call [[wait]].
45
 *
46
 * ```php
47
 *
48
 * Yii::$app->async->run(function () {
49
 *
50
 *      sleep(5);
51
 * })->wait();
52
 *
53
 * ```
54
 *
55
 * Run multi tasks:
56
 *
57
 * ```php
58
 *
59
 * Yii::$app->async->run(function () {
60
 *
61
 *      sleep(5);
62
 * });
63
 *
64
 * Yii::$app->async->run(function () {
65
 *
66
 *      sleep(5);
67
 * });
68
 *
69
 * Yii::$app->async->wait();
70
 * ```
71
 *
72
 * @property string $autoload path of autoload file for runtime task execute environment.
73

75
 * @property int $timeout of task executable.

Documentation introduced by
$process is of type object<Spatie\Async\Process\Runnable>, but the function expects a callable.

It seems like the type of the argument is not accepted by the function/method which you are calling.

In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug.

We suggest to add an explicit type cast like in the following example:

function acceptsInteger($int) { }

$x = '123'; // string "123"

// Instead of
acceptsInteger($x);

// we recommend to use
acceptsInteger((integer) $x);

Bug introduced by
It seems like \Yii::getAlias($autoload) targeting yii\BaseYii::getAlias() can also be of type boolean; however, Spatie\Async\Pool::autoload() does only seem to accept string, maybe add an additional type check?

This check looks at variables that are passed out again to other methods.

If the outgoing method call has stricter type requirements than the method itself, an issue is raised.

An additional type check may prevent trouble.

Documentation Bug introduced by
It seems like \Yii::getAlias($appConfigFile) can also be of type boolean. However, the property $appConfigFile is declared as type string. Maybe add an additional type check?

Our type inference engine has found a suspicous assignment of a value to a property. This check raises an issue when a value that can be of a mixed type is assigned to a property that is type hinted more strictly.

For example, imagine you have a variable $accountId that can either hold an Id object or false (if there is no account id yet). Your code now assigns that value to the id property of an instance of the Account class. This class holds a proper account, so the id value must no longer be false.

Either this assignment is in error or a type check should be added for that assignment.

class Id
{
    public $id;

    public function __construct($id)
    {
        $this->id = $id;
    }

}

class Account
{
    /** @var  Id $id */
    public $id;
}

$account_id = false;

if (starsAreRight()) {
    $account_id = new Id(42);
}

$account = new Account();
if ($account instanceof Id)
{
    $account->id = $account_id;
