Hi, everyone ,i am a novice of WebKit. I want to use it to parse html
and javascript and finally get the DOM of that html. But when i have
written a test programme and run it. The problem is happen, The memory
is grow up rapidly when i parse 1000 html pages that is download from
web. it use 1GB memory. i find some meory leak when i use Valgrind to
check it. The leak summary like this:

------------------------------------------------------------------------------------

----------------------------------

The test programme like this:

typedef struct
{
    WebKitWebView* webView;
    GMainLoop* loop;
}Fixture;

int main()
{

   //  retrieval files from dirctory
    vector<string> files;
    string dir = "htmlfile";
    readFiles(files,dir);
    string contnet;

// gtk init
    g_thread_init(NULL);
    gtk_init(NULL,NULL);

    fstream is;

// iterator files
    for(size_t i = 0; i < files.size() ; ++i)
    {
        string file = files.at(i);
        string tmp = dir;
        tmp.append("/");
        tmp.append(file);
        cout << "Reading file -> " << tmp << endl;
        is.open(tmp.c_str());

        readFile(file,is);   // read file content
        is.close();

        Fixture* fixture = new Fixture();

// create webView and loop
        fixture->webView = WEBKIT_WEB_VIEW (webkit_web_view_new ());
        fixture->loop = g_main_loop_new(NULL, TRUE);
        g_object_ref_sink(fixture->webView);

        webkit_web_view_load_string(WEBKIT_WEB_VIEW
(fixture->webView), file.c_str(), NULL, NULL, NULL);

        // run loop
        g_idle_add((GSourceFunc)finish_loading, fixture);
        g_main_loop_run(fixture->loop);

        // get title
        WebKitWebView* view = (WebKitWebView*)fixture->webView;
        WebKitDOMDocument* document = webkit_web_view_get_dom_document(view);
        gchar* title = webkit_dom_document_get_title(document);
        std::cout << "TT:" << title << std::endl;

        g_free(title);
        /////////////////
        g_object_unref(fixture->webView);
        g_main_loop_unref(fixture->loop);

        delete fixture;
    }

}

I use this command to compile the programme

g++ domtest.cpp -g3 -o domtest `pkg-config --cflags --libs webkit-1.0`
