I am able to download and compile both WebCore project and

I have created a custom executable (pointing to
/Application/Safari.app) in my WebCore project. The browser is
launched and I can set breakpoints in WebCore. But my question is how
can I set breakpoints in JavaScript engine?
e.g. I want to load www.cnn.com in the brower and i want it to break at
void Parser::parse(JSGlobalData* globalData, int* errLine, UString*
errMsg)
in JavaScriptCore (Parser.cpp).
Just open the source file and set a breakpoint. It should work. I do that
all the time.
Thank you. I tried the following, but it still does not work:
1. open WebCore xcode project (build and go (debug) runs fine, it
launches a Safari.app)
2. Go to File-Open, and open JavaScriptCore/parser/Parser.cpp
3. File, Parser.cpp, got opened in XCode.
4. Go to line 42, set a breakpoint, a Yellow with blue border'
bookmark showed up
void Parser::parse(JSGlobalData* globalData, int* errLine, UString* errMsg)
{
m_sourceElements = 0;
5. 'Build and Go' in Webkit project.
6. Load www.aol.com
But my breakpoint in JavaScript Parser never breaks.
Can you please tell me what am i missing? Any help is appreciated.
Thank you.
You can also create a custom executable in the JavaScriptCore project and
start Safari from there instead of the WebCore project.

There’s your mistake.
To quote the documentation for JSClassDefinition.
�...@field staticFunctions A JSStaticFunction array containing the class's
statically declared function properties. Pass NULL to specify no statically
declared function properties. The array must be terminated by a
JSStaticFunction whose name field is NULL.”
The JS_staticFuncs array is not terminated with a function with a name field
of NULL and must be. This should work better.
JSStaticFunction JS_staticFuncs[] =
{
{funcName, functionCallback, kJSPropertyAttributeNone},
{0, 0, 0}
};
Hope that helps!

There’s no clear definition for “asynchronous functions” so I can’t really answer that question. There are many JavaScript functions that do work and then later call a function to indicate the work is complete. If you’re using the JavaScriptCore API you can easily implement something like that. But you need to be sure to manipulate the JavaScript objects only on the same thread the JavaScript call comes in on. In the WebKit context that means only on the main thread. So you can do some work, and then make a call to a JavaScript function that the caller passed on the main thread. -- Darin ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev

HaKitchen/Counter were an attempt to push thinking in the right direction, not a real suggestion. Agree that this is a rat hole and it we need to move on. Still think Frontend/Backend is the clearest thing despite being used in a different manner in some other places and despite Client/Server(/Service) being used elsewhere. But Client/Service is my second choice.

Re: [webkit-dev] WebKit-Build
Hi Fred, Could it be that you did the checkout from under the Windows command line rather than from within CygWin? This messes it up, at least that was the cause for a similar issue I encountered. Everything worked fine when I re-did the checkout under CygWin. It's also the first time I see the link you posted - that patch shouldn't be necessary AFAIK. Also (someone correct me if I'm wrong), setting any windows environment variable also shouldn't be necessary, provided you set up the include paths in Visual Studio correctly. (The only environment variable you need is WEBKIT_TESTFONTS if you run layout tests on Windows - a whole 'nother can of worms). The errors you list below are auto-generated files. It seems the scripts that generate them haven't been run, probably due to some previous error (could be linked to the above issue).

Re: [webkit-dev] AppCache class naming (WAS Re: SharedWorkers alternate design)
one might reasonably assume that in Chrome, the renderer process is the back end Not really. We do use the terms front and back, but they usually refer to something a bit orthognal to this child/main process distinction... closer to network stack vs closer to browserui is generally what these terms refer to. Anyway... how these terms are used in chromium shouldn't influence our use of these terms in webcore much... in webcore-land we (me at least) were thinking 'front' == closer to script and html content, 'back' == farther away from that. I can make suggestions in the context of reviewing a patch if you guys don't want to discuss it any more. I'm not clear enough on how exactly you split the classes to make a good suggestion. That would be great. Here's a patch... https://bugs.webkit.org/show_bug.cgi?id=25436 ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
Re: [webkit-dev] WebKit-Build
Hi Roland, I did the checkout from cygwin, I do not think you can do it from DOS command. I tried one thing else and that seems to have done the trick. Reading the documents over and over I noticed they say copy the webkit to cygn\home\username\Webkit. In my build I did not have such structure, so I created a Home\username node under cygwin and copied Webkit there and tried to rebuild. It says the build is successful, I try to run it now :) Regarding the bug fix. When I checked out the code it gave me the choice between Windows Text format or Unix format, I chose Windows Text format (Should have stayed with default). I think that messed things up. Below is the result of the build. WebKit is now built. To run Safari with this newly-built code, use the WebKitTools/Scripts/run-safari script. NOTE: WebKit has been built with SVG support enabled. Safari will have SVG viewing capabilities. Your build supports the following (optional) SVG features: * Basic SVG animation. * SVG as image. * SVG fonts. * SVG foreign object. * SVG use support. The build created the following directories: C:\cygwin\home\username\WebKit\WebKitBuild\obj\InterfacesGenerated C:\cygwin\home\username\WebKit\WebKitBuild\obj\JavaScriptCore C:\cygwin\home\username\WebKit\WebKitBuild\obj\JavaScriptCoreGenerated C:\cygwin\home\username\WebKit\WebKitBuild\obj\record-memory-win C:\cygwin\home\username\WebKit\WebKitBuild\obj\WebCore C:\cygwin\home\username\WebKit\WebKitBuild\obj\WebKit Is this all it should be? Now I tried to run Safari from cygwin and I get notification below: $ run-safari 1 file(s) copied. 'FindSafari.exe' is not recognized as an internal or external command, operable program or batch file. Setting environment for using Microsoft Visual Studio 2005 x86 tools. When I search for FindSafari.exe it is not there. Thanks for all the help.

This messes it up, at least that was the cause for a similar issue I encountered. Everything worked fine when I re-did the checkout under CygWin. It's also the first time I see the link you posted - that patch shouldn't be necessary AFAIK. Also (someone correct me if I'm wrong), setting any windows environment variable also shouldn't be necessary, provided you set up the include paths in Visual Studio correctly. (The only environment variable you need is WEBKIT_TESTFONTS if you run layout tests on Windows - a whole 'nother can of worms). The errors you list below are auto-generated files. It seems the scripts that generate them haven't been run, probably due to some previous error (could be linked to the above issue).

Hi,
50% of time when I use gdb then arith functions works.
it may fail at 1st, or 3rd try, and 100% fail w/o gdb. I
just use jsc to do sth like 5%2, 5*3, etc.
It is with in call of ctiTrampoline(code, registerFile,
callFrame, jexception, pptr, globalData), jit code executed
and may be in last line of op_mod() when it tried to convert
result, gdb simply shows segment fault, or PC stops at an
non-coded area, w/o gdb it says invalid instruction. It may
be in JITcell,h in
ALWAYS_INLINE double JSValuePtr::toNumber(ExecState* exec)
const
{
return
JSImmediate::isImmediate(asValue()) ?
JSImmediate::toDouble(asValue()) :
asCell()-toNumber(exec);
}
due to exec pointer wrong.
if I continue to use same arithmatic function the generated
jit code won't call op_mod() unless it is the 1st time, I
think it is because jit code is already there. If another
thread handles the real operation and not sync'd then it may
be the case. Note I use BCM chip with two CPUs - BCM
customized SMP and BCM Linux.
when it works, before and after ctiTrampoline() the stack
is balanced and registers are ok. where is the jit stack and
how to check its balance?
when it fails, stacks shows we are nearby jit code - the
code w/o calling OP_mod() CPP function as it fails at 3rd
try. But PC points to a data structure:
any comments? thanks a lot!!

[webkit-dev] Rendering Video using video overlay rather than on a Cairo surface (Graphics overlay)
WebKit's Gstreamer Plugin ( MediaPlayerPrivateGstremaer ) creates a WebKit video sink plugin (VideoSinkGstreamer) which uses a Cairo surface to render video on. We are porting WebKit on a custom MIPS processor which has a dedicated video scalar on it. I want to render video using a video scalar instead of this Cairo surface. I came to know the video coordinates of the Videobox are inside paint function of MediaPlayerPrivateGstreamer.. If I disable the graphics plane entirely then I can see that video is positioned and scaled as requested by the layout engine but I just want to make the surface on top of videobox to be translucent , so that the underneath video is visible. What is the best way to do it? Thanks for helping, Ajit ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev

I came to know the video coordinates of the Videobox are inside paint function of MediaPlayerPrivateGstreamer.. What is the best way to do it? So what u can do is this: When the setSize/paint function gets called; size and rect indicate the visible video area to be displayed Setup the Attribute window to blend the Graphics over Video. In case you dont have an attribute window and use the Alpha bits in ARGB OSD mode ; then u will have to fill the necessary Alpha bits in your primary OSD plane ! Now the tough job is to blend Graphics/HTML controls that the page will render on top of the Video plane That may require some hacking in the Renderer to see whats below and ensure we tweak the Alpha bits to bring Graphics on top for those player controls alone (with transparency maintained as per CSS rules !)
