"php -e" causes segmentation fault #154

Closed marko-ilic closed 1 year ago

marko-ilic commented 3 years ago

When php script with the code for creating swoole server is run with php, everything works fine (except yasd), but if the script is run with option -e (php -e) segmentation fault will be returned.

Swoole version: 4.8.0

OS: 5.10.47-linuxkit x86_64 Linux gcc version 10.3.1 20210424 (Alpine 10.3.1_git20210424) PHP 8.0.11

How to reproduce: index.php file

<?php 

// ...

$server = new  Swoole\Http\Server("127.0.0.1", 9501);

$server->on("start", function (Server $server) {
    echo "Swoole http server is started at http://127.0.0.1:9501\n";
});

$server->on("request", function (Request $request, Response $response) {
    $response->header("Content-Type", "text/plain");
    $response->end("Hello World\n");
});

$server->start();

run the script with php -e index.php

output: Segmentation fault

yasd is installed with

git clone https://github.com/swoole/yasd.git \
    && cd yasd \
    && /usr/local/bin/phpize --clean \
    && /usr/local/bin/phpize \
    && ./configure \
    && make clean \
    && make \
    && make install

php -m

deminy commented 3 years ago

it seems that some use statements are missing. Could you please add them and try again?

<?php

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

// ...

BTW, I tested Swoole 4.8.0 with PHP 7.4 and 8.0 (using the script provided and following instructions here), and it worked fine.

marko-ilic commented 3 years ago

@deminy I didn't copy that part, but it's the same. Here is the whole script index.php

<?php

// update with the path to your vendor
require __DIR__ . '/../vendor/autoload.php';

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

$server = new Server("127.0.0.1", 9501);

$server->on("start", function (Server $server) {
    echo "Swoole http server is started at http://127.0.0.1:9501\n";
});

$server->on("request", function (Request $request, Response $response) {
    $response->header("Content-Type", "text/plain");
    $response->end("Hello World\n");
});

$server->start();

And just to mention it worked fine few weeks ago with swoole 4.7.0

deminy commented 3 years ago

I tested the code without the autoloading part, and it worked fine. Could you please remove the autoloading part, try again, and see if it still happens?

It it doesn't happen, there could some coding issue or compatibility issue with some Composer packages. It would be nice if you could include a reproducible code (with Composer and other details included).

marko-ilic commented 3 years ago

It's the same. I've created this simple example just to show what is the problem, and it's the same with or without autoload part. I have (apart from the project where the issue is the same) empty project with just index.php file and composer

...
    "require": {
        "php": "^8.0",
        "ext-swoole": "^4.8.0"
    },
...

And this issue is not only on one machine

Without -e swoole works fine (Swoole http server is started at http://127.0.0.1:9501)

UPDATE: I've tested it now with the swoole 4.7.0 and the error is the same (Segmentation fault). It was ok few weeks ago, so I'm not sure what can be the reason :-(

deminy commented 3 years ago

Tested on my Macbook as well with following installations. This time I didn't use Docker, but still don't see the issue.

A few weeks ago it worked.

Rastusik commented 3 years ago

UPDATE: it seems like it works again after I removed the blackfire extension

marko-ilic commented 3 years ago

It's the same in my case. It works after removing blackfire extension. Thanks @Rastusik

feelec-yishu commented 2 years ago

I don't want to install blackfilre. As long as I start yasd and run php -e, a segmentation fault (core dumped) will appear

huanghantao commented 1 year ago

Can consider to use swoole https://github.com/swoole/swoole-src/tree/support-xdebug

You can use xdebug directly, as long as the PHP version is 8.1 or greater
