$server->setting is NULL in onWorkerStart and onTask callback

[nguyenhothanhtam0709]

Issue:
I ran a simple http server script using swoole 6 and SWOOLE_THREAD mode, the var_dump($server->setting) of onTask and onWorkerStart callback show NULL, but in SWOOLE_PROCESS mode they show an setting array. Is this an expected behaviour or not?

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

I ran this script with Swoole 6

<?php

require_once __DIR__ . '/../vendor/autoload.php';

use Swoole\Constant;
use Swoole\Http\Request;
use Swoole\Http\Response;
use Swoole\Http\Server;

$server = new Server('0.0.0.0', 3001, SWOOLE_THREAD);
$server->set([
    'hook_flags' => SWOOLE_HOOK_ALL,
    'enable_coroutine' => true,
    'task_enable_coroutine' => false,
    'debug_mode' => true,
    'display_errors' => true,
    'enable_preemptive_scheduler' => true,
    'worker_num' => 4,
    'reactor_num' => 2,
    'task_worker_num' => 2
]);

$server->on(Constant::EVENT_WORKER_START, function (Server $server) {
    var_dump($server->setting);
    $pid = getmypid();
    printf("Worker start on $pid\n");
});

$server->on('Task', function (Server $server, $task) {
    var_dump($server->setting);
});

$server->on('request', function (Request $request, Response $response) use ($server) {
    $server->taskWaitMulti([
        "AA"
    ]);
    $response->end("OK");
});

$pid = getmypid();
printf("[thread] Server started at http://0.0.0.0:$server->port on process {$pid}\n");
$server->start();

2. What did you expect to see?

the var_dump($server->setting) of onTask and onWorkerStart callback show array of value.

3. What did you see instead?

the var_dump($server->setting) of onTask and onWorkerStart callback show NULL.

4. What version of Swoole are you using (show your php --ri swoole)?

it seems like $server-setting of workers and task workers are NULL when using SWOOLE_THREAD mode.
