RFC6455 Incompatibility

[adrum]

@mbonneau

I am doing some work on a ibrary that depends on this package, and this line is now causing an issue in the latest version:

Ratchet\RFC6455\Handshake\ClientNegotiator::__construct(): Argument #1 ($perMessageDeflateOptions) must be of type ?Ratchet\RFC6455\Handshake\PermessageDeflateOptions, GuzzleHttp\Psr7\HttpFactory given, called in .../vendor/ratchet/pawl/src/Connector.php on line 32 

When I change it to $this->_negotiator = new ClientNegotiator(null);, the test suite passes again.

It looks like it is also source of the issue reported here: laravel/reverb#310

I'm hitting the same problem. The issue here is the change in the constructor signature of \Ratchet\RFC6455\Handshake\ClientNegotiator between 0.3.x and 0.4:

(0.3.1):

    function __construct(PermessageDeflateOptions $perMessageDeflateOptions = null) {

(0.4.0):

    public function __construct(
        RequestFactoryInterface $requestFactory,
        ?PermessageDeflateOptions $perMessageDeflateOptions = null
    ) {

Since \Ratchet\Client\Connector::__construct() now passes the result of new gPsr\HttpFactory() as the first argument, this crashes if 0.3.x is installed.

This issue occurs while using both this package along with the websocket server package cboden/ratchet. The first depends on ^0.4.0 || ^0.3.1 of the ratchet/rfc6455 package while the latter still depends only on ^0.3.1.

in case people get here from google and got trouble to get this to work with ratchetphp/Ratchet.

just downgrade to "ratchet/pawl": "v0.4.1" and use the version of ratchetphp/Ratchet#1014 and it worked for me.

[dvdknaap]

if you want to fix this error:
vendor/ratchet/rfc6455/src/Handshake/ClientNegotiator.php:19

function __construct(?PermessageDeflateOptions $perMessageDeflateOptions = null) {

vendor/ratchet/pawl/src/Connector.php:29

$this->_negotiator = new ClientNegotiator(PermessageDeflateOptions::createDisabled());

also tried the following because it's in a test case but it didn't work in my case

$this->_negotiator = new ClientNegotiator(PermessageDeflateOptions::permessageDeflateSupported() ? PermessageDeflateOptions::createEnabled() : PermessageDeflateOptions::createDisabled());
