[webkit-dev] WebKit Architecture Document?
I am looking for architecture documentation for WebKit, which will explain to me how the code is organized and bring me up to speed to become a developer on WebKit. While I can see some good API documents (e.g., http://developer.apple.com/DOCUMENTATION/Cocoa/Conceptual/DisplayWebContent/DisplayWebContent.html), I don't see any good architecture or design documents. Any pointers will be very welcome. Thanks! ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
Re: [webkit-dev] WebKit Architecture Document?
Hi I have been working on Webkit since 2 Yrs. I have not seen of such document (not even talked of). The best way , which worked wonders for me, to understand Webkit is just Walk through code. Use some sensibility ;), try to set up execution environment and try to debug it. or May be u can design on and give back to community :) Thanks Regards Niilesh On Thu, Dec 4, 2008 at 5:49 PM, Shariq Rizvi [EMAIL PROTECTED] wrote: I am looking for architecture documentation for WebKit, which will explain to me how the code is organized and bring me up to speed to become a developer on WebKit.

That's the approach I am taking. or May be u can design on and give back to community :) This is a possibility. Perhaps if one of us can bootstrap the document then it can get maintained as a community effort. Will keep this in mind. thanks, Shariq Thanks Regards Niilesh On Thu, Dec 4, 2008 at 5:49 PM, Shariq Rizvi [EMAIL PROTECTED] wrote: I am looking for architecture documentation for WebKit, which will explain to me how the code is organized and bring me up to speed to become a developer on WebKit.

Re: [webkit-dev] Limiting the size of LocalStorage
I'd be happy to fix this bug and submit a patch when I am done. Before I can do that, I have a question - why is LocalStorgare created and tracked per page group and not per process, like offline storage databases are?

[webkit-dev] JavaScript memory management question
I'm working on an embedded product which uses a WebKit-based browser, and
I've been tracking down some memory leaks we're seeing. After a long while
of digging through the codebase, I've been able to determine that we're
occasionally leaking the WebCore::Document object when leaving certain
websites. A bit more tracing reveals that the Document object is being
retained because an HTMLImageElement holds a DocPtr reference on it, and the
element isn't going away when the normal refcount on the Document drops to
0. This pins the Document object in memory.
The specific site I've been testing with is www.yahoo.com. Examining the
source code to that page reveals the following in the page's beforeUnload
event:
window.onbeforeunload=function(){
var img=new Image;
now=new Date;
t6=now.getTime();
img.src='
http://www.yahoo.com/'+(ylp?ylp:'p.gif?t=0')+cc+'tid='+ver+'ni='+document.images.length+'sss='+sss+'t1='+t1+'d1='+(t2-t1)+'d2='+(t3-t1)+'d3='+(t4-t1)+'d4='+(t5-t1)+'d5='+(t6-t1)+'d6='+(t7-t1)+'d7='+(t8-t1)+'d8='+(t9-t1)+'d9='+(t10-t1)+'d10='+(t11-t1)+'d11='+(t12-t1);
}
It appears that this Image object is never being removed--I can repeatedly
navigate to and from this site and watch HTMLImageElements (and their
associated Document objects) pile up.
I'm still not convinced this is a WebKit problem specifically (there's a
fair amount of code surrounding it in our product that could potentially
have bugs in it), but to continue tracing the problem, I need to know what
the mechanism is that *ought* to be freeing this object. I presume this is
something that should be taken care of by the JavaScript garbage collector,
however I can see JavaScriptCore::Collector::collect() calls running
occasionally after this object is created, and it never goes away. Is there
some immediately apparent reason why this wouldn't be happening? I.e., is
there something else that would be holding a reference to an object created
by this type of script code, or is something other than the GC responsible
for freeing it, etc?
My apologies if this turns out to be a stupid question--I'm just trying to
get some context for where I ought to focus next.
Thanks,
Matt
