Hi list,
My goal is to create webkit/gtk based browser, which can be controlled
via Linux pipe (fifo).
I have made several test with webkit, but there is always "huge" memory
leaks.
I have used lastest webkit build: "WebKit r70732 was built on 28 October
2010".
I assume that the leak is in the cache(maybe I am wrong). Amount of the
memory leak is related to loaded page.
So, everything to disabling cache has done. I have also set: "m_disabled
= true " in the :"WebCore/loader/Cache.cpp"
I have tested both cache modes with out any effects for the memory leak:
- WEBKIT_CACHE_MODEL_WEB_BROWSER
- WEBKIT_CACHE_MODEL_DOCUMENT_VIEWER
And same result with all methods:
- webkit_web_view_reload_bypass_cache
- webkit_web_view_load_uri
- webkit_web_view_reload
Even if I run callback function once with "gtk_widget_destroy(wk);", it
does not release used memory.
Plese help me, I am desperate ;-)
Here is my testcode:
#include <gtk/gtk.h>
#include <webkit/webkit.h>
#include <stdlib.h>
#include <time.h>
static WebKitWebView* web_view;
static char *urls[] = {"http://www.utu.fi";,
"http://www.ts.fi";,
"http://www.hs.fi";,
"http://www.google.fi";,
"http://www.hs.fi";,
"http://www.turku.fi"};
gboolean callback (gpointer wk)
{
g_print("loading\n");
//webkit_web_view_load_uri(wk, urls[rand() % 6]);
//webkit_web_view_load_uri(wk, "http://www.hs.fi";);
webkit_web_view_reload_bypass_cache(wk);
return TRUE;
}
int main( int argc, char *argv[])
{
GtkWidget *window;
GtkWidget *vbox;
gtk_init(&argc, &argv);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_default_size(GTK_WINDOW(window), 1024, 768);
web_view = WEBKIT_WEB_VIEW(webkit_web_view_new ());
gtk_widget_set_size_request(GTK_WIDGET(web_view), 1024,768);
//webkit_set_cache_model(WEBKIT_CACHE_MODEL_WEB_BROWSER);
webkit_set_cache_model(WEBKIT_CACHE_MODEL_DOCUMENT_VIEWER);
WebKitWebSettings *settings = webkit_web_settings_new();
g_object_set(G_OBJECT(settings),
"enable-offline-web-application-cache", FALSE, NULL);
g_object_set(G_OBJECT(settings), "enable-private-browsing", TRUE,
NULL);
g_object_set(G_OBJECT(settings), "enable-scripts", FALSE, NULL);
g_object_set(G_OBJECT(settings), "enable-plugins", FALSE, NULL);
webkit_web_view_set_settings(web_view, settings);
WebKitWebBackForwardList *back_forward_list =
webkit_web_view_get_back_forward_list(web_view);
webkit_web_back_forward_list_set_limit(back_forward_list, 1);
gtk_container_add(GTK_CONTAINER (window), GTK_WIDGET(web_view));
webkit_web_view_load_uri(web_view, "http://www.hs.fi";);
gtk_widget_show_all(window);
g_timeout_add(12000, callback, web_view);
gtk_main();
return 0;
}
