Hi Guys and Girls,
Not sure if this is the right place to ask, but here it goes:
I am using Webkit2Gtk+ in my RSS-Reader to display the articles.
But I have issues when the user is switching very fast between articles
or the articles are very big/with lots of images or videos.
Once a new article is selected I immediately cancel the loading of the
current one with "stop_loading()".
Then I wait until the "load_failed"-signal is triggered with the
"webkit_network_error_cancelled" error. Only after that I start loading
the new article.
But still, sometimes after stopping the loading I receive
"load_changed"-events after the successful cancel.
Here is a small part of a log that displays the problem:
[ DEBUG ] ArticleView: load article 91799
[ DEBUG ] ArticleView: load STARTED
[ DEBUG ] ArticleView: load COMMITTED
[ DEBUG ] ArticleView: load FINISHED
[ DEBUG ] contentPage: set headerbar
[ DEBUG ] ArticleView: load article 92595
[ DEBUG ] ArticleView: load STARTED
[ DEBUG ] ArticleView: load COMMITTED
[ DEBUG ] contentPage: set headerbar
[ DEBUG ] ArticleView: load article 92675
[ DEBUG ] ArticleView: load FINISHED
[ DEBUG ] contentPage: set headerbar
[ DEBUG ] ArticleView: load article 93127
[ DEBUG ] ArticleView: load STARTED
[ DEBUG ] ArticleView: load COMMITTED
[ DEBUG ] contentPage: set headerbar
[ DEBUG ] ArticleView: load article 91940
[ DEBUG ] ArticleView: load FINISHED
As you can see the first article (91799) is loading fine. The second
one is (92595) is canceled before it is finished loading by the next
request (92675)
but the "WebKit.LoadEvent.FINISHED" is still reached afterwards. The
same problem with article 93127 that should be canceled by 91940.
Only difference is, article 93127 finishes loading after it should be
already canceled and article 91940 never starts loading.
So the wrong article is now shown in the article-view of my application.
Sometimes not only the wrong article is shown but only a white blank
page (but I could not reproduce this right now).
What I want the code to do is, load the requested article immediately
and cancel the old load request.
When a URL in the loaded article is clicked it should open in the
default browser.
This is the WebkitGtk+ relevant part of my code:

Or if someone wants to have a look at all of it:

Here is also a bug report of someone else having the same issues with
the application: https://bugs.launchpad.net/feedreader/+bug/1529872
Can anyone help me with this? :)
Thx in advance
Jan Lukas
