Do you have the xdebug extension? If so, try not using it and see.

Can confirm it's working on v5.1.1 (previous build)

NathanFreeman · 2024-05-15T02:22:27Z

@modrink I can not reproduce it, Is this a consistently reproducible scenario?
I am directly accessing 127.0.0.1:8000 without any business logic.

modrink · 2024-05-15T14:03:45Z

We have Cloudflare & Traefik V3 in front, but I'll test more when I get the chance. I was not able to reproduce this locally (only on server with the proxy). But Swoole v5.1.1 works and OpenSwoole latest works as well.

With Traefik the occurring errors are HTTP 499 and 502

robinnydahl · 2024-05-16T06:28:58Z

Hi all,

I'm afraid we have not yet had the time to fully make a reproducible case without sharing sensitive details, but I can confirm the issue is present in Swoole 5.1.2 and that reverting back to 5.1.1 solves the issue.

We have tested setting up a clean Laravel project with Octane using Swoole 5.1.2 inside a docker image running from php:8.2-cli-alpine and using mlocati/php-extension-installer to install Swoole. When reaching Swoole on port 8000 the service keeps running, the same goes for when we access it through NGINX inside the image as well.

The NGINX config inside the image looks like this:

map $http_upgrade $connection_upgrade {
    default upgrade;
    ''      close;
}
 
server {
    listen 80;
    listen [::]:80;
    server_name domain.com;
    server_tokens off;
    root /home/forge/domain.com/public;
 
    index index.php;
 
    charset utf-8;
 
    location /index.php {
        try_files /not_exists @octane;
    }
 
    location / {
        try_files $uri $uri/ @octane;
    }
 
    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }
 
    access_log off;
    error_log  /var/log/nginx/domain.com-error.log error;
 
    error_page 404 /index.php;
 
    location @octane {
        set $suffix "";
 
        if ($uri = /index.php) {
            set $suffix ?$query_string;
        }
 
        proxy_http_version 1.1;
        proxy_set_header Host $http_host;
        proxy_set_header Scheme $scheme;
        proxy_set_header SERVER_PORT $server_port;
        proxy_set_header REMOTE_ADDR $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $connection_upgrade;
 
        proxy_pass http://127.0.0.1:8000$suffix;
    }
}

The problem actually occurs when we are running the requests through the Kubernetes Ingress Controller which is also using NGINX behind the scenes. After the first request is made through the Kubernetes Ingress Controller the Swoole service shuts down, after this we are also unable to reach the Swoole endpoint directly within the environment as well.

I can concur with @modrink that the issue is that the client closes the connection (HTTP 499), so there seems to be something wrong with the implementation in the HTTP server that was introduced in 5.1.2 and that it's triggered mostly when using HTTP Proxies like NGNIX (with certain settings), Traefik and Cloudflare.

As mentioned we have not yet been able to reproduce this in a way to share yet.

NathanFreeman · 2024-05-16T08:06:17Z

@robinnydahl @modrink Perhaps some commits led to this issue.I'll take some time to test it.

NathanFreeman · 2024-05-19T07:50:08Z

@linuxd3v Can you provide a simple script for reproducing the error?

NathanFreeman · 2024-05-19T09:32:47Z

@linuxd3v I found that the max_nesting_level parameter of xdebug is set to 512. If a certain loop exceeds 512 times, a PHP Fatal error will be thrown, terminating the process.

linuxd3v · 2024-05-20T13:33:26Z

@NathanFreeman I've tried setting max_nesting_level to 50000 - but still seeing the same issue.
Actually - seeing the same issue with Swoole-v5.1.0 and Swoole-v5.1.1
Also tried xdebug 3.3.1 - but with the same result as xdebug 3.3.2.

NathanFreeman · 2024-05-20T13:36:58Z

@linuxd3v I don't have a good solution for xdebug. There are too many configurations for xdebug, unless you can find out through the logs which specific configuration is causing PHP to throw a fatal error.

NathanFreeman · 2024-05-24T12:45:04Z

@error1001es @robinnydahl @modrink I can not reproduce it.
Please use valgrind or gdb to trace the program execution.

It's worth noting that the trace doesn't always include frame 0. Sometimes it stops at zend_hash_str_update () (What is frame 1 in the trace above).

It's also worth noting that instead of PHP 8.2, we're using the php:8.3.7-cli-alpine20 base image. We also run Swoole using Laravel Octane.

Our Dockerfile is based on this example Dockerfile: https://github.com/swoole/docker-swoole/blob/master/dockerfiles/5.1.2/php8.3/alpine/Dockerfile

@HallexCosta @lv2u @error1001es @robinnydahl @modrink
We have released Swoole v5.1.3, optimized a dynamic array. You can try Swoole v5.1.3 to see if this issue still exists.

@NathanFreeman confirmed the issue has been resolved with v5.1.3 btw the Swoole was serving the request fine directly but failed behind an LB or Nginx

Are you using xdebug, or can you check the stack output using valgrind? @salkhwlani

salkhwlani · 2024-06-07T08:48:01Z

No, I don't use Xdebug; the issue is resolved once I update the swoole from 5.1.2 to version v5.1.3

lv2u · 2024-06-10T09:19:38Z

Confirming Swoole v5.1.3 fixes the issues described in this report.
