Ping and keepAlive in Ratchet

[SaphirAngel]

For those who want to ping or be sure that a client is present (internet lost, mobile network). We have implemented the following functions:
Ping and keepAlive
The only requirement is to have an instance of the loop event.
The commit is here : 6da3b04
Repo : https://github.com/bjtpartners/Ratchet/tree/ping-dev

There are no problem found at this time for and it's very reactive.
I will not make pull request because i use the Promise and Event Loop in Ratchet directly but i share the solution :).

If you are opinions or remarks, you're welcome :).

Just a quick question : Is there a way to get the loop event from the instance of a connection ? I have not found but you never know.

Bye :)

Thanks for tag.

Modification of last time.
I found for put the loop directly in IoConnection instance (simple but i misread).
I clean the code too (one day I will learn to code in php xD).
Commit : fe96e6b

More simple :).

And I also forgot: Thanks for Ratchet ! ;)

Nice work @SaphirAngel, thanks for sharing! I'll keep this issue open for people to check out. This functionality is something I'll add to the core once v0.2 of the RFC6455 library has been refactored.

[SaphirAngel]

It's a pleasure ! Good announcement for this functionality in core, good luck for development ! :)

PHP Catchable fatal error: Argument 2 passed to Ratchet\Server\IoConnection::__construct() must be an instance of React\EventLoop\LibEventLoop, instance of React\EventLoop\StreamSelectLoop given, called in /home/pi/serverapps/chattest/php/vendor/cboden/ratchet/src/Ratchet/Server/IoServer.php on line 94 and defined in /home/pi/serverapps/chattest/php/vendor/cboden/ratchet/src/Ratchet/Server/IoConnection.php on line 19

:( i tried to apply this fix but i have this error..

Hello,

Have you pass a EventLoop instance in the IoServer constructor ?

[fedyfausto]

this is my IoServer Class:

this is my IoConn class:

this is my server.php init:

and this is my app script:

Oh, yes, sorry for this.
This is the problem with no test (but I do not know to do, I confessed :x).

So, the problem is that for my test, i use the libevent pecl extension.
http://socketo.me/docs/deploy

I recommend to install this extension but the problem is present and i will try to push a correction within 24 hours.
Meanwhile you can :

• Install libevent pecl extension
• Change the code :
  The LibEventLoop parameter requirement by a LoopInterface (
  do not forget "use React\EventLoop\LoopInterface;" in use section).

Changes must be made in the files:
Ratchet/Server/IoConnection.php
Ratchet/WebSocket/Version/RFC6455/Connection.php

Sorry and thanks for feedback

[SaphirAngel]

It's ok.
I push modifications (just a changement finally).
The patch for ping accept all loop type.

Hello everyone, I'm having connection problems that get active and this ping / pong solution would help a lot.
I tried to download version 0.4 but it seems that it is still not stable.
Any forecast for official release?

[cboden]

it is still not stable

Have you experienced a bug in the 0.4 branch?

[filipecoelho]

pessoal, resolvi aqui e consegui usar a versão 0.4.
porém, estou tendo problemas com o memory_limit do PHP.
