3、 test code (设置'hook_flags' => SWOOLE_HOOK_ALL 必现)

<?php
$http = new Swoole\Http\Server('0.0.0.0', 9501);

$http->set([
    'worker_num' => 1,
    'enable_coroutine' => true,
    'hook_flags' => SWOOLE_HOOK_ALL
]);

$http->on('workerStart', function ($serv, $worker_id) {
    $fd = fopen('workerstart.log', 'a+');
    fwrite($fd, "workerStart: {$worker_id}\n");
    var_dump($fd);
});

$http->on('Request', function ($request, $response) {
    $response->header('Content-Type', 'text/html; charset=utf-8');
    $response->end('<h1>Hello Swoole. #' . rand(1000, 9999) . '</h1>');
});

$http->start();

开启io_uring后，设置hook_flag 包含 SWOOLE_HOOK_FILE 或者 SWOOLE_HOOK_STDIO 都会出现上面报错

错误码是38 ENOSYS，看一下内核版本信息是不是过低

bingcool commented 1 month ago

是在windows的系统上的基于alpine linux 3.20.3构建的docker里面跑的swoole，如果不设置 SWOOLE_HOOK_FILE 或者 SWOOLE_HOOK_STDIO，fopen()就不会报错。内核版本：

/home/wwwroot/swoolefy # uname -r
5.10.16.3-microsoft-standard-WSL2`

https://github.com/swoole/swoole-src/issues/5675 看看这个能不能帮你解决问题

NathanFreeman commented 1 month ago

windows的wsl可能没法完全模拟linux环境，导致有些功能不支持

matyhtf commented 1 month ago

参考：

应该是 linux 的 namespace 机制，禁止了 io_uring_queue_init 系统调用，需要修改 docker 的设置：

    security_opt:
      - seccomp:unconfined
