I am keen to start contributing as I'm about to begin using this library for a project I'm working on.

I don't have phpunit installed globally and since it now supports being installed with composer, I've added it as a dev dependency to make it easier to run the tests in this project.

One of the advantages of socket_recv is it returns the length of the data for you. I believe that method should take the $buffer parameter by ref and return the length as the php function does.

https://www.php.net/manual/en/function.fmod

        $usec = $sec === null ? null : fmod($sec, 1) * 1e6;

        $ret = @socket_select($r, $w, $e, (int)$sec, (int)$usec);

What do you think about this?

IPv6 no longer present The major change that is coming with this migration is that local and external IPv6 networking will no longer be present. This has been present and while technically not considered to be a feature, it has been available. With the move to GCE this will no longer work, until such time as as GCE adds IPv6 support. We do understand this may cause a disruption for some use cases and while we have considered numerous ways to try to provide IPv6 in the cloud, none of the current available options are suitable for a large production deployment. We ask for your understanding and patience with the fact that is will no be supported for the near future.

Just very short, because it's already late here.

I sometimes see this uncaught exception

PHP Fatal error: Uncaught exception 'Socket\Raw\Exception' with message 'Socket operation failed: Success'

The "Success" is already strange on it's own. It seems, that this is related to non-blocking streams. The error code is 0 and I couldn't find any reference to this error code, so I assume, that the manual is in this case not very accurate and all functions can also return false simply if they don't have something to return.

Should fix #25

I've pulled the environment tests (unix + ipv6) into their own object and used this inside the Factory tests.

If this is merged, should we utilise the new Environment object inside the Factory itself? For instance, throwing a custom exception inside createTcp6() with a nice message stating that IPv6 support is not available.

I've left the TODO markers next to their respective checks - what can be done to test these checks thoroughly

So, I'm trying to send POST to a server with your lib, but I don't know what am I missing while writing data to host... $socket->write( "POST /test.php?var=1 HTTP/1.1rn" ); $socket->write( "Host: localhostrn" ); $socket->write( "User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:24.0) Gecko/20100101 Firefox/24.0rn" ); $socket->write( "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8rn" ); $socket->write( "Accept-Language: pl,en-us;q=0.7,en;q=0.3rn" ); $socket->write( "Accept-Encoding: gzip, deflatern" ); $socket->write( "Cookie: " . $cookie . "rn" ); $socket->write( "Connection: keep-alivern" ); $socket->write( "rn" );

Hi, i'm using the library with udp sockets, every works perfectly, but sometimes the server reply (ack) is lost and the script is left waiting for a reply.

I've set the timeout value, but it seems it's only set when creating the socket.

Anyone might know what i'm missing?

Thanks to all

with a third party library (https://github.com/jonjomckay/quahog) we get this stack trace:

vendor/sentry/sentry/lib/Raven/ErrorHandler.php in socket_last_error vendor/clue/socket-raw/src/Exception.php in createFromSocketResource at line 21 vendor/clue/socket-raw/src/Socket.php in getOption at line 176 vendor/clue/socket-raw/src/Socket.php in assertAlive at line 478

it is a E_WARNING caused by assertAlive() socket operation on an invalid resource. Added error handling code to avoid raising E_WARNINGs in assertAlive()

My IDE reveals the Factory class has two cases where an undefined variable is used, $scheme. I think this is used for write-back, but nevertheless it will raise a notice unnecessarily. This can be fixed by setting the var to something prior to using it:

$scheme = null; // Prevents 'Undefined variable' notice
$socket = $this->createFromString($address, $scheme);

I can send a PR if that is helpful.

So I am creating server and connecting multiple clients

Server.PHP

<?php
include_once 'vendor/autoload.php';
$factory = new \Socket\Raw\Factory();
$socket = $factory->createServer('localhost:9999');
$socket->listen(10);
echo "Waiting for incoming connections... \n";

while(1) {
    $client = $socket->accept();
    $client_info = $client->getPeerName();
    if($client_info != null) {
        print 'Connect Client :-'.$client_info."\n";     
    }
    $data = $client->read(1024000);
    print $data."\n";
    $client->write('Agent said: '.$data);
}

Client

<?php
include_once 'vendor/autoload.php';
$factory = new \Socket\Raw\Factory();

$socket = $factory->createClient('localhost:9999');
echo 'Connected to ' . $socket->getPeerName() . PHP_EOL;

$index = 0;


// receive and dump HTTP response
//var_dump($socket->read(8192));
while(1) {
$socket->write("Client is here \n");
}

When I execute the code it just connects one client and in Server window it shows entry of one client only as Connect Client :-127.0.0.1:63031

2nd , only sending data it throws error:

Fatal error: Uncaught exception 'Socket\Raw\Exception' with message 'Socket operation failed: Broken pipe (SOCKET_EPIPE)' in /abc/Server/vendor/clue/socket-raw/src/Exception.php:55
