Using this project you can also use ssh or ftp to sync remotely: https://github.com/Coppertino/github-webhook.

All I ever get from this is a blank $result and no results from the git pull. I've even modified your code to help me try to diagnose the problem. I followed your guide but used my own name (smart) in place of www-data as that's who already owns the repo.

   $descriptorspec = array(
        1 => array('pipe', 'w'), // stdout is a pipe that the child will write to
        2 => array('pipe', 'w')
    );
    $resource = proc_open($cmd, $descriptorspec, $pipes, $cwd);
    if (is_resource($resource)) {
        stream_set_blocking($pipes[2], 0);
        if ($err = stream_get_contents($pipes[2]))
        {
            return 'Process could not be started [' . $err . ']';
        }
        $output = stream_get_contents($pipes[1]);
        fclose($pipes[1]);
        proc_close($resource);
        return $output;
    } else {
        return "No resource provided.";
    }

Figured it out. I had several things going on.

  1. Copied .ssh folder to /var/www so apache could connect to github
  2. git repo-config core.sharedRepository true
  3. chown/chmod g+rw .git folder specifically (-R . or -R * doesn't hit the .git folder)

I also modified the function above to have better error output if there is a fatal error in the command executed.

private function _syscall ($cmd, $cwd)
{
    $descriptorspec = array(
        1 => array('pipe', 'w'), // stdout is a pipe that the child will write to
        2 => array('pipe', 'w') //stderr will pipe back
    );
    $resource = proc_open($cmd, $descriptorspec, $pipes, $cwd);
    if (is_resource($resource)) {
        stream_set_blocking($pipes[2], 0);
        if ($err = stream_get_contents($pipes[2]))
        {
            return 'Process could not be started [' . $err . ']';
        }
        $output = stream_get_contents($pipes[1]);
        if ($err = stream_get_contents($pipes[2]))
        {
            return $err;
        }
        fclose($pipes[1]);
        proc_close($resource);
        return $output;
    } else {
        return "No resource provided.";
    }
}

@joefresco Or you can just use [suPHP|http://www.suphp.org/Home.html] to make your php script that does git pull execute under your user instead of apache. No more crazy chmod/chown :)

Thanks for your feedback @joefresco.

I have just recently done this again, and updated my guide.

It's worth noting that in your guide there's a more straightforward way to update your known_hosts file that more closely follows github documentation:

sudo -u www-data ssh -T git@github.com
