Problem with send to worker under Firefix but not Chrome

zsimpson commented 13 years ago

The following code executes perfectly under Chrome but acts like the second call to "send" to the worker thread fails under Firefox.

main_thread

<html>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.js"></script>
<script src="/javascripts/jquery.hive.js"></script>
<script type="text/javascript">
    var frameComplete = true;

    $(document).ready( function() {
        startThread();
        runOneFrame();
    });

    function startThread() {
        // DELETE the old thread
        // PROBLEM: Acting like this isn't doing anything
        $.Hive.destroy();

        // LAUNCH a new thread
        $.Hive.create({
            count: 1,
            worker: '/javascripts/play_worker_test.js',
            receive: function (data) {
                if( data.cmd == "done" ) {
                    console.log( "recvd frame complete" );
                    frameComplete = true;
                }
            },  
        });

        $.Hive.get(0).send( "go" );

        frameComplete = true;
    }

    function runOneFrame() {
        if( frameComplete ) {
            if( $.Hive.get(0) ) {
                console.log( "sending frame start" );
                $.Hive.get(0).send( "go" );
                frameComplete = false;
            }
        }
        setTimeout( runOneFrame, 1 );
    }

</script>

</html>

worker

importScripts('/javascripts/jquery.hive.pollen.js');

$(function( data ) {
    for( var i=0; i<1000000000; i++ ) {
    }
    $.send( { "cmd":"done" } );
});

This is bad news, it seems to just take a long time to respond... ~7 seconds

How about Opera and Safari?

rwaldron commented 13 years ago

Safari uses the same implementation of the Worker constructor as Chrome (its in WebKit). Opera is untested

rwaldron commented 13 years ago

Incidentally, I was wrong in assuming the implementations would perform the same... http://gyazo.com/d2a433aff3d6bee9eca87148c561cb07.png
