Web Audio API
by Chris Rogers 25 Aug '10

25 Aug '10

Over the past months I've been refining the web audio API implementation that I've been developing in the 'audio' branch of WebKit (per Maciej's recommendation). The API has been through a good amount of review by WebKit developers at Apple, Google, and in the W3C Audio Incubator group. For those who are interested, the draft specification is here: http://chromium.googlecode.com/svn/trunk/samples/audio/specification/specif… I have working demos here: http://chromium.googlecode.com/svn/trunk/samples/audio/index.html I'll be posting a series of patches to migrate the working code from the audio branch to WebKit trunk. Most of the files are new, with only a few places which will touch existing WebKit files (such as EventTarget, Event). The files will be conditionally compiled. I'm considering using the following enable: #if ENABLE(AUDIOCONTEXT) After discussing the directory layout in some detail with Eric Carlson, Chris Marrin, Simon Fraser, and Jer Noble, we've decided that the files will primarily live in two places: WebCore/audio WebCore/platform/audio I know that some had expressed concern that a directory called 'audio' in WebCore would be confused with the audio element. The reason I think 'audio' would be a good name is because the API does have a direct relationship to the audio element and, over time, when the API becomes more broadly used will be associated with the audio capabilities of the web platform. That said, if anybody has grave concerns over this name, then we can discuss alternatives. Anyway, I just wanted to bring these coming changes to everyone's attention. Regards, Chris Rogers

Null value for QualifiedName
by Ryosuke Niwa 24 Aug '10

24 Aug '10

Greetings all, While working on the bug 44288<https://bugs.webkit.org/show_bug.cgi?id=44288>, it came to my attention that the default constructor of QualifiedName is behind a flag QNAME_DEFAULT_CONSTRUCTOR, and I can't find a qualified name that stands for invalid / null value. Is there any designated qualified name object that stands for invalid / null value? Invalid / null qualified name will be useful in the context like: http://trac.webkit.org/browser/trunk/WebCore/editing/markup.cpp?rev=65854#L… : void MarkupAccumulator::appendText(Vector<UChar>& out, Text* text) { const QualifiedName* parentName = 0; if (text->parentElement()) parentName = &static_cast<Element*>(text->parentElement())->tagQName(); if (parentName && (*parentName == scriptTag || *parentName == styleTag || *parentName == xmpTag)) { appendUCharRange(out, ucharRange(text, m_range)); return; } if (!shouldAnnotate() || (parentName && *parentName == textareaTag)) { appendEscapedContent(out, ucharRange(text, m_range), text->document()->isHTMLDocument()); return; } ... where I obtain the qualified name of the parent element which may or may not exist. If we had a null qualified name, above code can be re-written as: void MarkupAccumulator::appendText(Vector<UChar>& out, Text* text) { QualifiedName parentName = nullName; if (text->parentElement()) parentName = &static_cast<Element*>(text->parentElement())->tagQName(); if (parentName == scriptTag || parentName == styleTag || parentName == xmpTag) { appendUCharRange(out, ucharRange(text, m_range)); return; } if (!shouldAnnotate() || parentName == textareaTag) { appendEscapedContent(out, ucharRange(text, m_range), text->document()->isHTMLDocument()); return; } ... IMHO, new code is easier to read and has very little drawbacks (possible slowdown use to construction of QualifiedName). I could have used htmlTag or any other qualified name different from the four names used above, but that wouldn't be semantically correct. Ryosuke Niwa Software Engineer Google Inc.

Layout Tests Crashing on Snow Leopard

Started yesterday. A bunch of layout tests crash in some ASSERT in WebKitPluginHost / testnetscapeplugin. // Entry points extern "C" NPError STDCALL NP_Initialize(NPNetscapeFuncs *browserFuncs) { #if XP_WIN // Simulate Flash and QuickTime's behavior of crashing when NP_Initialize is called before NP_GetEntryPoints. if (!getEntryPointsWasCalled) CRASH(); #elif XP_MACOSX // Simulate Silverlight's behavior of crashing when NP_GetEntryPoints is called before NP_Initialize. if (getEntryPointsWasCalled) CRASH(); // THIS IS THE CRASH WE'RE HITTING. #endif Seems someone borked something this weekend. Thoughts?

Qt bots and EWS are building WebKit2 by default now
by Andras Becsi 24 Aug '10

24 Aug '10

Dear WebKit Community, in the past weeks we have worked on refactoring and stabilizing the build of the Qt port of WebKit2 and since the Windows and Snow Leopard bots and EWS build WebKit2 by default for some time now, we also decided to expand our QA coverage to include the WebKit2 build. This is only a local setting so it only affects the buildbots and EWS and doesn't change the default build using build-webkit. If someone wants to hack on WebKit2 for Qt he/she has to pass the "--qmakearg=CONFIG+=webkit2" option to build-webkit or set this option in the BUILD_WEBKIT_ARGS environment variable. We hereby kindly ask WebKit2 developers to also heed the Qt EWS and buildbots if submitting patches, and contact us if something does not work as expected. With best regards: WebKit2 Workgroup of the University of Szeged http://webkit.sed.hu Balazs Kelemen (kbalazs, kb {at} inf {dot} u-szeged {dot} hu) Zoltan Horvath (Zoltan, zoltan {at} webkit {dot} org) Andras Becsi (bbandix, abecsi {at} webkit {dot} org)

build.webkit.org
by Adam Barth 24 Aug '10

24 Aug '10

Hi webkit-dev, I landed the last piece of the HTML5 parser tonight. Unfortunately, build.webkit.org is super slow for some reason, so it's hard for me to see what's going on with the bots. I think I've got most things cleaned up, but there might still be some residual redness in Qt and/or Snow Leopard. I'm going to go to sleep now, but hopefully the web site will be working better tomorrow and I can fix whatever I broke. Thanks for your patience, Adam

DeviceOrientation/Motion on Document rather than Page
by Dean Jackson 24 Aug '10

24 Aug '10

Hi, I've been looking into implementing the clients for DeviceOrientation/Motion Events. Currently, the controllers for these events are members of Page. I think they are better suited on Document. Here are a few reasons: - Page isn't tied to any actual web page or document. Would we want to share the same controller and client across multiple web pages? I don't think so. - Document is already the place that is listening for these events - It's easy to suspend and resume the client from the Document-level when the user navigates to another page, or the document enters the cache, or a platform needs to temporarily suspend events for some reason. - When the API is on Page, it is hidden in the WebView, from where it is difficult to access. - it would allow the client to live in WebCore. This avoids tweaking the WebView implementations for all platforms to pass messages back and forth https://bugs.webkit.org/show_bug.cgi?id=41616 I assume one of the advantages of having them on Page is that it allows a Mock Controller to be easily created for testing from Dump Render Tree. Am I right? Is this that important? FWIW, Geolocation seems to take both approaches. One implementation is down in Navigator/Document/DOMWindow, but the mock controller is on Page. I've found the low-level approach much easier to implement. Thoughts? Dean

What is this wscript file in the root directory of WebKit? If it's a script, maybe we should move it to WebKitTools/Scripts? Adam

Layout bug with <table align="center">?
by Martin Sourada 23 Aug '10

Hi, there seems to be a bug in webkit (affecting webkitgtk, qtwebit and chromium) which leads to incorrect rendering of: http://www.flumotion.com/first_webm_live_event.php I can reproduce it with midori (webkitgtk), arora (qtwebkit) and chromium, haven't tried anything else. Looks like the problem lies in interpretation of align=center inside table element. It behaves differently from what I'd expect after trying other options (like align=left or align=right) and it is different from firefox. The reason I'm asking here first before filling a bug is to be 100 % sure it's a bug in webkit and not in the above mentioned page +firefox... webkitgtk is 1.2.3, qtwebkit is the one shipped with 4.6.3 (arora says it's webkit 532.4) and chromium 6.0.476.0 (0).

Can someone explain tx/ty?
by Eric Seidel 23 Aug '10

I believe int tx, int ty -- which we see sprinkled around the rendering tree -- are the offset from the top left corner of the current renderer's parent to the containing block. Is that correct? In SVG we use IntSize containingBlockOffset in the rare places we have to deal with this RenderBoxModelObject-only concept. I've long considered fixing renders to use IntPoint and IntSize instead of x, y, tx, ty, but to do that, I need to make sure I understand what tx, ty are, and what name they should have as an IntSize. -eric
