Unable to establish SSL connection with Pawl

[slowbro]

Hi again, cboden. I'm having issues connecting to wss:// sockets with Pawl on a new machine. I've been banging my head against this for about 6 hours now to no avail.

I'm starting with a brand new install of Pawl, using the test script provided, connecting to "wss://echo.websocket.org":

<?php

    require __DIR__ . '/vendor/autoload.php';

    $loop = React\EventLoop\Factory::create();
    $connector = new Ratchet\Client\Factory($loop);

    $connector('wss://echo.websocket.org')->then(function(Ratchet\Client\WebSocket $conn) {
        $conn->on('message', function($msg) {
            echo "Received: {$msg}\n";
        });

        $conn->send('Hello World!');
    }, function($e) use ($loop) {
        echo "Could not connect: {$e->getMessage()}\n";
        $loop->stop();
    });

    $loop->run();

        "ratchet/pawl": "dev-master"

What seems to happen is that when connecting, it just hangs. like so..

# USING ws://
[slowbro@slowbro test]$ php test.php
Received: Hello World!
^C

# USING wss://
[slowbro@slowbro test]$ php test.php
#... HANGS FOREVER WITHOUT OUTPUT ...

I'm at a complete loss here. From my debugging it looks like the steam_get_contents in vendor/react/socket-client/src/SecureStream.php handleData is blocking.. but the stream is set to be nonblocking?

I'm so confuse-frustrated :(

[slowbro]

This probably belongs in the socket-client project, as it seems to be what's killing the whole deal (even using Devistro/phpws..)

[slowbro]

More info, because I hate sleep:

This works if I downgrade to react/socket-client 0.4.2 EXCEPT for this change:
reactphp-legacy/socket-client@3cc2bfd

compsison:
reactphp-legacy/socket-client@v0.4.2...v0.4.3

edit: AND, holy shit, they fixed the original bug: https://bugs.php.net/bug.php?id=41631
from our original conversation.. reactphp-legacy/socket-client#24

[onekit]

Did you have connected with your WSS without pawl with regular browser to make sure is WSS is done and work properly?

I guess WSS not configured.

[slowbro]

Yep. This is connecting to a known-good WSS.

[cboden]

I pushed a change to socket-client master that should provide a fix for PHP version 5.6.8. I'm still working on fixing other versions but if you can force that branch see if that fixes your issue for now.

[slowbro]

Yeah, that seems to fix it. I receive the echo back from the wss:// connection with socket-client dev-master.

[slowbro]

Coincidentally, that branch also fixes another bug with stream_get_contents hanging with Slack again for some reason.. working 100% now! Thanks @cboden, you're the best <3

[cboden]

Happy to help @slowbro. The amount of debug info you provide makes my life so much easier! :-)
