Description Allan Sandfeld 2008-08-26 12:10:36 UTC

Version:            (using KDE 4.1.0)
Installed from:    Compiled From Sources

When entering this page: http://forum.cafeen.org/index.php?showtopic=837&st=1760&start=1760
Konqueror stalls and enters an infinite recursion. This is a regression from 3.5.9, but also existed in KDE 4.0.

I have a few backtraces from the recursion here:

While the code does seems to enter the slow path of uncached indexes it doesn't seem like the loop is here, but instead seems to originate from JavaScript.

Comment 1 Maksim Orlovich 2008-08-26 18:03:27 UTC

IRC discussion summary:
it loops infinitely because it keeps revisiting the same node, as it should 
since the collection is live.

Further analysis:
After debugging a bit w/Opera, it also revisits the image, but skips over it the next time it visits. Something is wrong with out ::width, I guess.

Comment 2 Maksim Orlovich 2008-08-26 18:41:01 UTC

Well, it's getting it from m_renderer->contentWidth(), after doing 
updateRendering(), but it still gets the stale value, not what it set.

Actually, even the below fails, returning 0:
<img src="http://www.kde.org/media/images/top-kde.jpg" id="img">

<script>
function test() {
  var i = document.getElementById("img");
  //alert(i);
  alert(i.width);
}

</script>
<body onload="test()">

Comment 3 Maksim Orlovich 2008-08-26 20:09:06 UTC

Allan: Q: how is the size of the image supposed to be recomputed from updateRendering/recalcStyle? It does the new style computation, then diffs them, and returns NoInherit the first time it's changed. Then only recalcStyle gets called and that's it --- how should some sort of a relayout/recompute size method be invoked? I can see that RenderObject::setStyle will call setNeedsLayoutAndMinMaxRecalc, as well as dirtyFormattingContext, but that just sets bits, doesn't it?

It seems like this ought to be synchronous for things like offsetWidth, etc., too. Oh. That calls updateLayout and not updateRendering.

How about this:

Should note: The original reported case was solved by patch by Maksim. A test-case is now needed, and the duplicates may be unrelated but similar issue.
