HTML 5 Audio "progress" event is sending undefined values in webkit nightly

• Component: Media
• Status: RESOLVED INVALID

[Joseph Huckaby]

The HTML 5 Audio "progress" event is supposed to send the number of bytes loaded, and the number of total bytes in the audio track.  This works perfectly in production Safari 4.0.4, but in the webkit nightly build (6531.21.10, r51669), the progress event sends back "undefined" values.

void HTMLMediaElement::initAndDispatchProgressEvent(const AtomicString& eventName)
{
    bool totalKnown = m_player && m_player->totalBytesKnown();
    unsigned loaded = m_player ? m_player->bytesLoaded() : 0;
    unsigned total = m_player ? m_player->totalBytes() : 0;
    dispatchProgressEvent(eventName, totalKnown, loaded, total);
    if (renderer())
        renderer()->updateFromElement();
}

Per bug 30513 this appears to be correct behavior.

Correct, progress events were removed from the HTML5 spec in r4133. See http://html5.org/tools/web-apps-tracker?from=4132&to=4133
