Hi,

below are some basic things you would need to compile your webkit-gtk
port for any targeted system(e.g. Arm)

1. Get some cross compilation environment from compiling webkit on
your machine but targeting some other system like arm. E.g.
scratchbox, the one you mentioned, etc.

2. Get the require toolchain which will actually have tools/bins
reuired to compile your code for target machine(E.g. Arm)

3.  you will also have to cross compile/build all the dependencies
required to build webkit.

4. here is the list of webkit-gtk port dependencies:
o Gtk+ (might be on X or DirectFb), it needs lot of
dependencies to be built and installed first, google search  it for
build details, packages, etc.
o gperf
o flex
o bison
o curl(libcurl)
o sqlite
o icu4c-4.0(libicu)
o libXslt

5. Build webkit
o Get the latest source
o ./autogen.sh && make && make install

Refer webkit.org/google (https://trac.webkit.org/wiki/BuildingGtk) for
more details.

Re: [webkit-dev] want to port JIT to MIPS - why GtkLaunder needs gcc?

[Jenson Lui]

Hello,

  Do you mean the Programs/GtkLauncher? Since the GtkLauncher is a wrapper
script and will create the actual lt-GtkLauncher under
Programs/.libs/.  My way is to
just run the Programs/GtkLauncher in host (with your cross toolchain
in PATH) and let
the script create the lt-GtkLauncher. Just ignore the error and copy the
Programs/.libs/lt-GtkLauncher created to your target.
 Hope this helps.

Jenson

[webkit-dev] the variable of JavaScript function

[zhenghe zhang]

Hi
There is a javaScript function, as follow:
Function test()
{
Var a = 3;
Var b = 2;
Print(a+b);
}
There are two variables, and the identifiers will stored in the
identifierTable. When running the function, it will print "5".
When running the code "print(a+b)",it will use "3" to replace "a" and "2"
replace "b". I don't know how to do it through the c++ functions. I hope you
tell!
Thank you & best regards

Apparently, any javascript containing page is enough to trigger the
crash. The default homepage, google.com does trigger it, and the much
simpler alert() testcase i found with a quick search crashes too.
http://liblearn.osu.edu/tutor/jscript.html

I'll give a try to breakpoints when I'll have the occasion.

I'd suggest trying to produce a reduction of the test case your  
looking at – JIT crashers can usually be reduced down to a very small  
test case.  You may then want to step though the JIT code to see where  
the bogus value is coming from.  Adding calls to breakpoint() from  
JIT::privateCompile and JIT::privateCompileMainPass can help with  
this, inserting breakpoints into the JIT code that the debugger will  
then hit.

You might try the files in the JavaScriptCore/API/tests/ directory.  I haven't 
used the API before, so I'm not sure where any good examples would be.

Re: [webkit-dev] How to compile WebKit GTK+ port from ARM processor?

[x yz]

I do mips not arm, but after setup cross compiler tool chain the compilation is 
the same as on native X86 platform. 
for how to setup tool chain, you would got help from Internet.
after you set up tool chain, you will need to compile extra libs. how to 
compile libs is also another issue.

It appears it's not exactly a corrupted stack, yet, it's sad the JIT
code doesn't do the right thing to allow gdb to trace back to earlier
frames.

Anyways, it really does crash in JSC::JITStubs::cti_op_call_NotJSFunction.
To be more precise, it crashes on the following line:
CallType callType = funcVal.getCallData(callData);
which is actually:
inline CallType JSValuePtr::getCallData(CallData& callData)
{
return JSImmediate::isImmediate(asValue()) ? CallTypeNone : 
asCell()->getCallData(callData);
}

It appears asCell() here is returning something wrong (not NULL).

An earlier call to JSC::JITStubs::cti_op_call_NotJSFunction works and a lot
of other stub functions are called before the crash, so it means most of
the JIT works, but it is failing in a subtle way.

Would someone with JIT knowledge have some hints to debug this crasher ?

Cheers,

Mike

Re: [webkit-dev] Use SquirrelFishExtreme Alone, Many Questions

[Brian Barnes]

Thank you David, a couple more quick questions and I should be on my 
way.  First off, the API is very similar to SpiderMonkey's, so that's a 
good thing.  Second, following the links I found some example code for 
contexts, evaluating, rooting (very important in my case) and calling 
functions in scripts.  Is there good example code for:


(1) adding an object to the global objects that has it's own functions 
and properties

(2) getting call backs for getters, setters, etc, in objects

This looks doable.  I'm still not sure about the win32 version, though.  
I'm assuming I might want to build the javascriptcore myself to shield 
myself from changing versions of Safari.

Yes.  Squirrelfish Extreme ("SFX") is an implementation "detail" (albeit a very 
significant detail :) of the JavaScriptCore framework.

Yes, it's JavaScriptCore.  Yes it's also an Xcode project.

Yes, it's a C interface.

You can build JSC stand-alone (and thus get the SFX) without the rest of 
WebCore.

As example, if you build the Qt port (QtWebKit), see 
http://trac.webkit.org/wiki/BuildingQtOnLinux on how to do that, you will get 
the JS interpreter at WebKitBuild/Release/JavaScriptCore/jsc.

[webkit-dev] Use SquirrelFishExtreme Alone, Many Questions

[Brian Barnes]

I'm working on v3 of my 3D engine dim3, it's a complete rewrite in a 
number of areas (for instance going to GLSL, new physics, etc).  The 
last thing I'm looking at is the javascript engine that runs the 
scripting.  Right now I'm using SpiderMonkey 1.7, and I'm investigating 
moving away from that for a couple reasons.  So, I googled, looked at 
the wiki, and can't seem to find the answers for these, though they seem 
like obvious things so I might have just missed it.


1) Can I compile SFE alone (without webkit)
2) Are there XCode and MVC projects (for SPE alone), and is the XCode 
project a framework?

3) Where are the SPE API docs online?
4) Is there a C interface (obviously I can't find the docs :) )

Pointing me to the API docs would be an extreme help right off the bat, 
as it would tell me how ugly the switch over would be.  Sorry for the 
beginner questions, but I'm trying to evaluate and can't seem to find 
the information I need.

Subject: [webkit-changes] the variable of JavaScript function

Hi
There is a javaScript function, as follow:
Function test()
{
Var a = 3;
Var b = 2;
Print(a+b);
}
There are two variables, and the identifiers will stored in the
identifierTable. When running the function, it will print "5".
When running the code "print(a+b)",it will use "3" to replace "a"  
and "2"
replace "b". I don't know how to do it through the c++ functions. I  
hope you

tell!
Thank you & best regards

Re: [webkit-dev] about WebCore\bindings\scripts documents

[David Kilzer]

The *.idl files are a custom Interface Definition Language for generating 
source code for DOM bindings.  On the Apple Mac port, there are (generally 
speaking) two such bindings built for each *.idl file:

- JavaScript bindings in C++ created by CodeGeneratorJS.pm; these files are the 
glue between JavaScriptCore and the C++ implementation files in WebCore.  They 
make the HTML DOM work in the web browser.

- Objective-C DOM bindings created by CodeGeneratorObjC.pm; these files provide 
an interface nearly identical to the HTML DOM interface in JavaScript, except 
in the Objective-C language.

Do you see the same problems with Safari? CFNetwork DLL is not

FWIW, it crashes with a corrupted stack:
(gdb) bt
#0  0x7fd115002c00 in ?? ()
#1  0x7fd11f4f6d26 in JSC::JITStubs::cti_op_call_NotJSFunction 
(args=0x7fff27e13820) at ../JavaScriptCore/runtime/JSCell.h:206
#2  0x7fd11fc55a3a in ?? ()
#3  0x in ?? ()

I'll investigate later today.

Oh thanks, that was it. I removed one PLATFORM(MAC) for ENABLE_JIT but
missed the one for ALTERNATE_JSIMMEDIATE. It built. I'll check if it
works (and will probably enable it in the debian packages, so that it is
