Bug 17151 – REGRESSION : "subresources" array has a strange behavior

• Component: WebKit API
• Status: NEW

[Yann]

I had a WebKit program, wich implement WebResourceLoad Delegate like this :

- (id)webView:(WebView *)sender identifierForInitialRequest:(NSURLRequest *)request fromDataSource:(WebDataSource *)dataSource
{
        return [request URL];
}

-(void)webView:(WebView *)sender resource:(id)identifier didFinishLoadingFromDataSource:(WebDataSource *)dataSource
{ 
        WebResource *r = [dataSource subresourceForURL:identifier];
        [self doStuff:[r data]]; 
}


Prior to 10.4.11 it worked well.
Now (Safari 3 ?), resources aren't all in [dataSource subresources]. It seems that  resources which doesn't need to be cached are missing.
So it is impossible to get all the downloaded content from a webView.


(Sorry for my bad english).

Is this the reason for missing resources in Safari's Activity window?

No, I don't think.
Some resources are in the Safari's Activity Window, but they aren't in the "subresources" array.

Would it be possible for you to make an example application for this problem? As is, the bug report is not really actionable.

An exemple application for this problem :
http://ynn.free.fr/MiniBrowser_test.zip

This is a modification of Apple MiniBrowser exemple.
I Added a table which contains a list of files used by the webpage : files which aren't in the subresources array are colored in red.

I haven't attempted to reproduce this, but I believe that there is enough information to proceed now, confirming the bug.

This bug still occurs, despite those other two bugs being fixed.
