Re: [webkit-dev] How does Zooming Work?
After chatting with David Hyatt, the answer seems to be, in my own words, "smack your fingers with a ruler." My current layout() method leaves with the RenderMathRow instance and some of its descendants needing layout. That's a violation of the API contract for layout(). I should make sure I don't need layout at the end by adding: setNeedsLayout(false); That would have caused my current implementation to fail to do what I wanted. The simple fix for me is to call RenderBlock::layout() again within the context of my method. If that causes other problems, I'll have to deal with those problems individually. For now, that fixes my problems with zoom. -- --Alex Milowski "The excellence of grammar as a guide is proportional to the paucity of the inflexions, i.e. to the degree of analysis effected by the language considered."

An alternative, less likely, explanation is that your objects > have anonymous children, but they don’t propagate the style changes > correctly to those children. The style changes seem to be propagating properly. I've dug into this quite a bit more. Here's the layout method for mrow that attempts to notify the math operators to stretch to a certain height: void RenderMathRow::layout() { RenderBlock::layout(); // calculate the maximum height int maxHeight = 0; int currentHeight = offsetHeight(); RenderObject* current = firstChild(); while (current) { if (current->isBoxModelObject()) { RenderBoxModelObject* box = toRenderBoxModelObject(current); // Check to see if this box has a larger height if (box->offsetHeight()>maxHeight) maxHeight = box->offsetHeight(); } current = current->nextSibling(); } if (maxHeight!=currentHeight) { style()->setHeight(Length(maxHeight,Fixed)); setNeedsLayoutAndPrefWidthsRecalc(); // notify contained operators they may need to relayout their stretched operators current = firstChild(); while (current) { if (current->isRenderMathOperator()) { RenderMathOperator* mathop = toRenderMathOperator(current); mathop->stretchOperator(maxHeight); } current = current->nextSibling(); } } } I modify the style of the mrow (a copy of the style) and change the height of the container (the mrow). This code correctly works the first time and will adjust properly after a zoom in/out if you resize the window. The stretchOperator() method marks the child as needing layout. As the children of mrow are stacked as a set of inlines (mostly likely all inline-block), there must be something that is not propagating. Also, I notice on a zoom in that the render tree for the MathML is being partially recreated. New instances of the children of mrow are created. Their initial layout() call then does not have the new maxHeight value. Afterwards, they are marked for layout just as in the initial layout. I've narrowed the problem down to this sequence of events: 1. RenderMathRow::layout() is called (from the outside) 2. RenderMathRow::layout() calls RenderBlock::layout() 3. Subsequent calls to RenderMathOperator::layout() are causes by (2). The stretch height has not been set at that moment. 4. If the height has changed: a. The height of RenderMathRow is set and it is told it needs layout b. Each RenderMathOperator child is notified of the stretch height and told it needs layout. 5. RenderMathRow::layout() is called (from the outside) 6. RenderMathRow::layout() calls RenderBlock::layout() 7. Subsequent calls to RenderMathOperator::layout() are causes by (2). The stetch height is now set properly and the height of the inline-block is now correct. What is interesting is that after a zoom, 1-4 happen. 5-7 only happen after a resize event. My suspicion is that even though the RenderMathRow instance has marked itself and its RenderMathOperator children as needing layout, that is somehow not noticed until the window resize. I can solve this right now by adding another call to RenderBlock::layout() in the RenderMathRow::layout() method. I shouldn't have to do that and I've noticed that such direct "double" calls can cause other problems. Any ideas what is wrong? Do I need to notify the parent of RenderMathRow somehow? -- --Alex Milowski "The excellence of grammar as a guide is proportional to the paucity of the inflexions, i.e. to the degree of analysis effected by the language considered."

Re: [webkit-dev] Regarding WebKit Support Libraries
Hi Jason, We actually changed our network implementation long ago. The one that is in sync with the tree is part of the private support library and we won't be releasing source for it at this time. The one that is in the repository and not in sync is in fact not used, but at one time did work.

As far as I'm concerned, that's ok for testing, even though we would not want to ship that way. If the state is so bad that we don't even want people testing, then the feature should be compiled out entirely. In my opinion, anyway. Without a SocketStreamHandle implementation, there is probably nothing people can test - as there will be no network activity at all. - WBR, Alexey Proskuryakov ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
Re: [webkit-dev] Partial SVG repaint
SVG was designed to support this, it's just not been turned on yet. It would be one little patch and a lot of little patches afterwards to fix things that break. :) You'd just add a checks in RenderSVGContainer and RenderPath to see if the dirty rect intersected the repaintRectInLocalCoordinates. http://trac.webkit.org/browser/trunk/WebCore/rendering/RenderSVGContainer.cpp#L92 http://trac.webkit.org/browser/trunk/WebCore/rendering/RenderPath.cpp#L115 I think that could add a bunch of under-painting bugs, but theoretically if of stored bounding box calculations are correct, then such a change should be fine. I'm not sure I would suggest such a change as your first change to WebKit though. It could have lots of fallout. :) -eric On Tue, Oct 6, 2009 at 4:05 PM, Patrick Roland Gansterer wrote: > I want to fix https://bugs.webkit.org/show_bug.cgi?id=30055. > > What is the prefered solution? > Where is the best place to start? > If i start the work i might ends up in one big patch.

Re: [webkit-dev] compileOpCallSetupArgs
Hi Zoltan. Sounds like a bug. (I tend to dislike #ifdefs like JIT_OPTIMIZE_CALL because of their tendency to fall prey to bit rot like this.) Loading the callee into regT1, regT0 is best. I'd recommend changing ! JIT_OPTIMIZE_CALL to respect that convention. Geoff On Oct 7, 2009, at 6:54 AM, Zoltan Herczeg wrote: Hi, I am not sure this is a bug, so I am curios about your opinion.

Do you think you could use HTML5/Canvas for the charts like the Chromium folks do? And do you think it would be possible to document the setup?

Hi All, I hope that a lot of you are regularly visiting our benchmarking site at http://www.sed.hu/webkit :) . As you might know, the performance and memory consumption of JavaScriptCore is measured on x86 Linux and Mac platforms, on several benchmark suites, on a regular basis, and visualized in the form of nice charts. Moreover, we also have a website called WebKit Apocrypha at http://webkit.sed.hu/, where we used to write blog posts. (We have been quite busy with other things in the last weeks - shame on us - but new posts are ahead!) Now, we are merging these two together. From now on, the benchmark charts are available as an integrated part of our Apocrypha site: http://webkit.sed.hu/benchmark . The old site is still alive, but not for long. Integration is not the only new issue, we started benchmarking on ARM as well. Come, and have a look! All comments are very welcome! (BTW, if you do an advanced query for the results of the last month - say, from 7th of September till 7th of October - you can see that a performance improvement happened on 1st of October on all platforms. That's when TCmalloc got enabled by default for the Qt port. http://trac.webkit.org/changeset/48976 ) Regards, Akos ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
