v4.4.0使用Swoole\Event::add监听inotify异常 #2673

wangritian · 2019-07-10T03:53:35Z

v4.4.0使用Swoole\Event::add监听inotify，文件变动时服务器segment fault，v4.3.5正常

请在程序末尾添加Event::wait()，另外，请贴出相关代码。

use Swoole\Event as swEvent; ... $this->inotify = inotify_init(); ... swEvent::add($this->inotify, function ($inotify) { ... }

查了一下文档，PHP7.3版本是否不需要加wait了？
v4.3.5版本该代码正常运行，4.4.0更新后，一旦监听的文件变动产生事件，服务器就会崩溃
尝试过在回调函数的第一行打印日志，没有成功

4.4版本需要在末尾添加Event::wait()
请使用USE_ZEND_ALLOC=0 valgrind php your_file.php跟踪程序执行，贴出屏幕输出的错误信息

matyhtf · 2019-07-10T05:52:40Z

<?php
$fd = inotify_init();
$watch_descriptor = inotify_add_watch($fd, __FILE__, IN_ATTRIB);

swoole_event_add($fd, function($fd) {
    $info = inotify_read($fd);
    $queue_len = inotify_queue_len($fd);
    var_dump($info, $queue_len);
}, null, SWOOLE_EVENT_READ);

写了一个最简单的程序，无法重现你的问题。

我在Swoole\Http\Server->start()之前，添加了Event::wait()，仍然报错，最后一块信息如下：

<?php
$fd = inotify_init();
$watch_descriptor = inotify_add_watch($fd, __FILE__, IN_ATTRIB);

swoole_event_add($fd, function($fd) {
    $info = inotify_read($fd);
    $queue_len = inotify_queue_len($fd);
    var_dump($info, $queue_len);
}, null, SWOOLE_EVENT_READ);

写了一个最简单的程序，无法重现你的问题。

我inotify监听的事件是：IN_MODIFY | IN_CREATE | IN_DELETE | IN_MOVE | IN_ISDIR

您好，重新编译v4.4.0后，仍然崩溃，是否需要提供更多信息？

切换到master分支已经可以了，刚刚是指定的tag，感谢
