報(bào)告bug：php8中workerman遇到異常會(huì)卡死不能重新fork一個(gè)子進(jìn)程
代碼：
global $worker;
$worker = new Worker();
Worker::$pidFile = '/dev/shm/jmworker.pid';
$worker->onWorkerStart = function(){
global $worker,$sec;
$sec = 0.5;
\Workerman\Lib\Timer::add($sec, function (){
echo '333333333333333';
//exit();
1/0;
},true);
};
// 運(yùn)行worker
Worker::runAll();遇到異常就會(huì)卡死不會(huì)退出進(jìn)程，也不會(huì)重新fork一個(gè)子進(jìn)程。執(zhí)行exit()也不會(huì)、
比如數(shù)據(jù)庫(kù)暫時(shí)無(wú)法連接，出現(xiàn)異常，就會(huì)導(dǎo)致子進(jìn)程卡死不會(huì)退出，也不會(huì)重新fork一個(gè)子進(jìn)程。

@6279:我沒使用workman，我是用webman，php8/php7 只要編譯參數(shù)里包含了sigchild的話就會(huì)出現(xiàn)異常，php官方有人提bug了，你可以看看php -i|grep configure

大佬，麻煩看一下包含了sigchild嗎
你代碼有致命錯(cuò)誤，退出才是正常行為。workerman 在你進(jìn)程出現(xiàn)致命錯(cuò)誤之后就會(huì)重新 fork 一個(gè)進(jìn)程的，但是你的致命錯(cuò)誤又沒有合理地處理，就會(huì)重復(fù)以上步驟。

對(duì)啊，遇到錯(cuò)誤之后應(yīng)該重新fork一個(gè)進(jìn)程，但是我貼出來的代碼不會(huì)重新fork一個(gè)進(jìn)程。你測(cè)試了代碼嗎

@6279:補(bǔ)充一下。我用的是 React EventLoop，你可能用的是 event。剛剛對(duì)比了一下，react 的 eventloop 的 add 方法，臨時(shí)想到了兩個(gè)解決方法。
一、修改 Events/EventInterface.php 中的 add 方法修改為 public function add($fd, $flag, $func, array $args = []); 再將 Events/Event.php 中的 add 方法簽名修改為 public function add($fd, $flag, $func, array $args = [])；
二、自己在你的定時(shí)器中加上 try {} catch (Throwable $e) { echo $e->getMessage(), "\n"; }，注意php7之后才可以 catch 錯(cuò)誤，跟異常不一樣的； -

我剛測(cè)試了，
同樣配置下，
php7 + event + libevent2 表現(xiàn)正常。
php8 + event + libevent2 表現(xiàn)異常。
其中event和libevent2 是 相同版本的。
而且問題只有在Timer裡才會(huì)發(fā)生，
我是在FileMonitor裡，
實(shí)例化時(shí)添加1/0;
這時(shí)候php7/8 都會(huì)自動(dòng)重啟。
如果在實(shí)例化添加Timer::add.....，
php7 會(huì)重啟，
php8 會(huì)一直報(bào)錯(cuò)Failed to invoke event callback。
補(bǔ)充下：
opcache開啟關(guān)閉都試過，結(jié)果一樣。

如果使用select模型不會(huì)出錯(cuò)，只有event的timer才會(huì)異常，
感覺是event的問題。
還是使用php7.4，有高版本要求的就把event轉(zhuǎn)為select模型吧。
