About event loop , where does it run?

[Marol]

1. What did you do? If possible, provide a simple script for reproducing the error.

Reactor threads are created in the Master process to handle client side network connections and network I\O.

So , request callback will execute from reactor thread , then callback function will execute from work process , won't it ?

$workerState = new WorkerState;

$workerState->cacheTable = require __DIR__.'/createSwooleCacheTable.php';
$workerState->timerTable = $timerTable;
$workerState->tables = require __DIR__.'/createSwooleTables.php';


$server->on('request', function ($request, $response) use ($server, $workerState, $serverState) {
    $workerState->lastRequestTime = microtime(true);

    if ($workerState->timerTable) {
        $workerState->timerTable->set($workerState->workerId, [
            'worker_pid' => $workerState->workerPid,
            'time' => time(),
            'fd' => $request->fd,
        ]);
    }

    $workerState->worker->handle(...$workerState->client->marshalRequest(new RequestContext([
        'swooleRequest' => $request,
        'swooleResponse' => $response,
        'publicPath' => $serverState['publicPath'],
        'octaneConfig' => $serverState['octaneConfig'],
    ])));

    if ($workerState->timerTable) {
        $workerState->timerTable->del($workerState->workerId);
    }
});

2. What did you expect to see?

I don't know  Where  does the `worker`  property value of  $workerState  set  ?   How do it ?

3. What did you see instead?

I  echo $workerState->workerId  , value is always 12 ,  because dispatch_mode default 2.  but ,  when  worker is setted  and  how?

Can you provide some hints or suggestions for understanding this logic？   thks very mush.
