WebSockets extension for Pathfinder

pathfinder_websocket's Issues

Websocket server using 100% of CPU all the time

I recently configured Websockets for my own Pathfinder instance, and immediately upon starting the websocket server from this project, it uses all the CPU on my AWS server (t2.small) even without any incoming connections. For everything else on the server (mysql, php-fpm, nginx, etc.) performance has never been an issue as I have a small number of users.

Because of this, Websockets actually perform worse for me than the fallback Ajax method as the server takes longer to respond to requests.

I initially configured websockets for v.1.2.0, but performed the upgrade process all the way to v.1.2.3 to see if that would help, and it has not (this is what I expected, since it is the websocket server that is the problem, and this project has not changed recently).

Here is the rest of the server information from my /setup page:

If you need any other diagnostic information please let me know.

Socket connection test fails.

I'm running into an issue with the testWebSocket failing on the /setup route.

Here's the output of php cmd.php

It seems to be failing somewhere around here: https://github.com/exodus4d/pathfinder/blob/master/public/js/v1.2.0/app/setup.js#L4222

I added a var_dump( $data ) at app/Main/MapUpdate.php on line 407 to see what was happening during the test. It returned the first healthCheck task and proper data but afterwards it looked like it was sending some blank data causing it to fail.

I haven't been able to dive into it too much but wanted to reported in case anyone had ideas.

Segmentation fault

The WebSocket server is working great (client can connect) but I keep having this error "Segmentation fault", which of course crash the websocket server. It seems to happen when a client disconnect.

Any idea of what it could be ?

Installation question

Hi,

i have limited knowledge in this server setup stuff - especially nginx - so i have no idea on how to install the websockets properly. I hope someone can point me in the right direction, please.

So far i have a local working pathfinder setup (all green, except websockets) on a virtualbox, network bridged debian stretch server called "debian". I can reach it with http://debian in my network.

• pathfinder is located in /var/www/pathfinder (pathfinder.conf in /etc/nginx/sites...)

• websocket is located in /var/www/pathfinder_websockets (i "git cloned it" and executed composer install, adjusted owner and permissions, no errors)

• I can start "php cmd.php" and it seems to be running.

But http://debian/setup can not see it. I guess i am missing some steps.

Is it ok to install the websocket in a new directory in /var/www ?
Do i need another nginx config for the websocket in /etc/nginx/sites...?
Do i need to add something to the pathfinder.conf in /etc/nginx/sites...?
Both of the last?
