head.ready('<label>') firing before script being loaded if taking too long

See original GitHub issue

I’ve noticed that head.ready seems to fire the “loaded”-event although the script with the specified label hasn’t even loaded fully. This is especially impacting slow connections and big scripts like e.g. jQuery. In my opinion there seems to be something fundamentally broken in head.js

I’ve made a proof of concept (which is also on http://playground.herndl.org/headjs_330/)

<?php

if (isset($_GET['js'])) {
    $js = $_GET['js'];

    header('Content-Type: text/javascript');

    if ($js == 'fast')
        echo 'debug("loaded script \'fast\'");';
    else if ($js == 'slow') {
        sleep(10);
        echo 'debug("loaded script \'slow\'");';
    }
    exit;
}

?>
<!DOCTYPE html>
<html>
<head>
    <title><?php echo $_SERVER['SERVER_NAME']; ?></title>
    <meta charset=UTF-8>
    <script type="text/javascript" src="head.min.js"></script>
</head>
<body>
    <pre id="output"></pre>
    <script type="text/javascript">
        function debug(text) {
            //console.log(text); // this does not work in old IE
            document.getElementById('output').innerHTML += '<br>' + text;
        }
        head.ready('fast', function() {
            debug("'fast' ready event fired");
        });
        head.ready('slow', function() {
            debug("'slow' ready event fired");
        });

        debug("start loading script 'fast' and 'slow'");
        head.load({fast: '?js=fast'}, {slow: '?js=slow'});
    </script>
</body>
</html>

It outputs

start loading script ‘fast’ and ‘slow’ loaded script ‘fast’ ‘fast’ ready event fired ‘slow’ ready event fired loaded script ‘slow’

I would love to see this getting fixed as well as the other open issues here on github, but the project seems to be dead?

I noticed this too. I also posted a request of info about future planning. it really REALLY would be nice if the original developer or whoever is working this to pop by and say something. I don’t understand why its so difficult to be transparent. login into your github account and say something pretty please? post on the blog? twitter? For pete’s sake its 2015! @WhoeverTheHeckIsDeveloping/SupportingHeadJS
