[Webkit] Debug QtWebkit with Visual Studio 2010.

1. Install Tools

• Install Visual Studio 2010
• Install VS2010 SP1.  (http://www.microsoft.com/zh-tw/download/confirmation.aspx?id=23691)

2. Get qt source code
Doload qt 4.8.5 from following address.
http://download.qt-project.org/official_releases/qt/4.8/4.8.5/qt-everywhere-opensource-src-4.8.5.zip

Decompress qt source code at D:\qt-4.8.5


3. Add path
Add D:\qt-4.8.5\bin to the Path variable


4. Run Visual Studio 2005 Command Prompt
Execute following commands in the VS command prompt:

cd D:\qt-4.8.5

configure –opensource -confirm-license –no-qt3support –debug –webkit –platform win32-msvc2010

Wait few minutes.

Remove the illegal quote characters “ and ” at line 327 in
D:\qt-4.8.5\src\3rdparty\webkit\Source\WebCore\platform\DefaultLocalizationStrategy.cpp if VC stops compiling this file.

Execute following command in the VS command prompt:

nmake

5. Debug Webkit
Use VC 2010 to open and build D:\qt-4.8.5\src\3rdparty\webkit\Source\Webkit.sln
Set QtWebkit as start project.
Right click on QtWebkit project -> Properties -> Configuration Properties -> Debugging -> Set Command as C:\qt-4.8.5\examples\webkit\fancybrowser\debug\fancybrowser.exe

Tar tool brief manual.

Tar
tar is a tool for file compression on Linux, you can compress files into other format , like gzip (.tar.gz), bzip2 (.tar.bz2) and so on.

Compress Format
tar [cvfz] [tar ball file] [the files or directory are compressed in]

c          Create a tar ball
f          Specify tar ball file name
v          Show the processing verbose.
z          Compress to gzip format.

Example
tar zcvf etc.tar.gz /etc/*

Decompress Format
tar [-xvfz] [tar ball file] [target directory for decompressing out]

x             Decompress tar ball
f             Specify tar ball file name
v             Show the processing verbose.
z             Decompress for gzip format.(.gz)

Example
tar zxvf etc.tar.gz /home/

[Webkit] Function flow for javascript JIT execution.

Just a memo for myself to remark function flow of JIT execution.

HTMLTokenizer::scriptHandler                  // start from here to handle script

    HTMLTokenizer::scriptExecution

    ScriptController::executeScript

        Completion::evaluate

            Executable::complie               // Compile script

                 Parser::parse

            bytecodegenerator::generate       // generate byte code



            Interpreter::execute

                Executable::JITCode

                Executable::GenerateJITCode   // Compile and generateJITCode

                    JIT::Compile

                JITCode::execute              // execute JIT code

return to HTMLTokenizer::scriptHandler

Now, we generated some JIT code for basic execution demand and byte code objects for whole script.
Then, we have to compile byte code objects to JIT code for executing each function in script.

CallData::Call     // Get byte code object and compile to JIT code for each call

    Interpreter::executeCall

    JITCodeforCall::executable

        Executable::generateJITCodeforCall

    JIT::Compile

    JITCode::execute

return to CallData::Call

Step by step to compile a C++ program on Ubuntu.

Reference:
http://www.wikihow.com/Compile-a-C/C%2B%2B-Program-on-Ubuntu-Linux

1. Install compiling tool

sudo apt-get install build-essential

2.Create a directory to hold your programs

mkdir -p CCPP/HelloWorld

3. Go into the directory you created.

cd CCPP/HelloWorld

4. Create CPP file

gedit main.cpp

5. Fill code in main.cpp and save it.

#include<iostream>
using namespace std;
int main()
{
    cout << "\nHello World !\n" << endl;
    return(0);
}

6. Compile it.

g++ -Wall -W -Werror main.cpp -o HelloWorldCPP

7. Execute it.

./HelloWorldCPP
