object-＆gt; ref_count＆gt; 0使用webkitgtk时断言失败

标签： webkit gtk

我正在尝试创建托盘菜单的应用。其中一个托盘菜单项创建一个连接到登录服务的窗口。然而，尽管它似乎有效，但我仍然得到断言失败。我必须做一些简单的错误，但是什么呢？

以下程序演示了这个问题。

TEST.CPP 

#include <gtk/gtk.h>
#include <webkit/webkit.h>
#include <stdlib.h>

int main(int argc, char* argv[])
{
  GtkWidget     * web_window = NULL;
  WebKitWebView * web_view = NULL;

  gtk_init(0L, 0L);

  if (web_window = gtk_window_new(GTK_WINDOW_TOPLEVEL)){
    //g_object_ref(G_OBJECT(web_window));
    gtk_window_set_default_size(GTK_WINDOW(web_window), 800, 600);

    g_signal_connect(web_window, "delete_event", G_CALLBACK(gtk_widget_hide_on_delete), NULL);

    if (web_view = WEBKIT_WEB_VIEW(webkit_web_view_new())){
      //g_object_ref(G_OBJECT(web_view));
      gtk_window_set_title(GTK_WINDOW(web_window), "Web View Test");
      gtk_container_add(GTK_CONTAINER(web_window), GTK_WIDGET(web_view));

      webkit_web_view_load_uri(web_view, "http://www.google.com/");
      gtk_widget_grab_focus(GTK_WIDGET(web_view));

      gtk_widget_show_all(web_window);
      gtk_window_present(GTK_WINDOW(web_window));

      gtk_main();
    }
    else
      printf("Failed to create WebView\n");
  }
  return 0;
}

编译：

g++ test.cpp $(pkg-config --cflags --libs webkitgtk-3.0) $(pkg-config --cflags --libs gtk+-3.0)

打开窗口并加载URL后，我看到这些断言失败：

(a.out:20179): GLib-GObject-CRITICAL **: g_object_ref: assertion 'object->ref_count > 0' failed

(a.out:20179): GLib-GObject-CRITICAL **: g_object_unref: assertion 'object->ref_count > 0' failed

当我然后单击关闭按钮（应隐藏窗口）时，我会看到这些断言失败：

(a.out:20179): GLib-GObject-CRITICAL **: g_object_ref: assertion 'object->ref_count > 0' failed

(a.out:20179): GLib-GObject-CRITICAL **: g_object_unref: assertion 'object->ref_count > 0' failed

正如您所看到的，我尝试将引用计数添加到web_window和web_view以查看问题是否存在，但它没有任何区别。

启用G_DEBUG =致命警告产生了一个核心转储，我在下面用gdb回溯。

很自然地认为您做错了事，但是当遇到GLib-GObject-CRITICAL失败时，问题几乎与代码无关，而与GNOME生态系统无关。

例如，通过在较旧版本的GNOME上运行它们，我可以在C ++ / Python中用完善的项目和准系统GTK + 3应用程序重现此问题，但该问题在最新版本的GNOME中消失了。

由于我没有在两次测试之间修改代码，所以代码必须没问题。

如果考虑到计划中的过时开发，强迫软件用户升级GNOME以便使用它，那么今天可能就不再发行了。

但是，如果您是针对旧版本的GNOME进行开发，或者由于某种原因而在最新版本的GNOME中出现此（或新的）GLib-GObject-CRITICAL故障，那么最简单的解决方案是将其过滤掉。

我个人将在适用的情况下进行单元测试，并忽略以下GLib-GObject-CRITICAL故障模式：

  • object->ref_count > 0
  • source->priv != NULL
