[webkit-dev] how to konw the identifier

2009-03-26 Thread 张正和
Hi all
There is a js function:
input type=text id=text1 value=Hello World /
function test(){ alert(text1.value); }

when webkit obtains an identifier(e.g. text1),how does webkit parse the 
identifier and how to konw that the identifier is the html's ID?

where is the html's ID stored?
thank you  bast regards
zzh

Re: [webkit-dev] JSxxxRelease/Retain - some guidance?

Here’s a little more beyond what Maciej said:

That’s JSValueProtect and JSValueUnprotect.

OTOH, I know there's some kind of Release/Retain dance in the  
ObjectiveC world as it relates to the memory management scheme of  
using pools to manage memory. Release/Retain could be related to that.


It’s not.

If I'm doing straight up C programming, no Cocoa, or Obj-C stuff at  
all, do I need to worry about this stuff at all, or is there a  
common pattern I should be using?


Yes, none of this has anything to do with Objective-C.

JSClass, JSContextGroup, JSGlobalContext, JSPropertyNameArray, and  
JSString are all reference counted, not garbage collected. The  
functions that return these objects follow the The Create Rule,  
borrowed from CoreFoundation http://developer.apple.com/documentation/CoreFoundation/Conceptual/CFMemoryMgmt/Concepts/Ownership.html 
.

Perfect.  I was looking for a link like that.  I posted a feedback note

Re: [webkit-dev] constant pool space and jit

2009-03-26 Thread Geoffrey Garen
I was wondering whether it is possible to remove the constant pool  
area in

jit.


It is.


RegisterFile contents right now:
... [ CallFrame ] [ Cleared const pool ] [ temporary SF  
registers ] ...


(SF means SquirellFish)

The constant pool is only used by interpreter, the jit simply clears  
the
area. It is not important on desktop systems, because of the big  
caches,
but in arm, that is a waste of cache space. I think shifting the  
remporary
SF registers by the size of the constant pool and changing some  
variables

(i.e: m_numConstants set to 0) in the CodeBlock during jit compilation
might be enough to implement this optimization. Do you agree?


Yes.

[webkit-dev] Windows build ENABLE(ASSEMBLER)

2009-03-26 Thread Kevin Ollivier

Hi all,

I'm trying to get a box ready to be a Windows build bot for the wx  
port, and while trying to build WebKit I've come across an issue with  
ENABLE(ASSEMBLER). Apparently this gets enabled only for Safari Win or  
Mac as it depends on HAVE(JIT) or HAVE(WREC) being set, but if  
HAVE(VIRTUALALLOC) is true (which is set to true under  
PLATFORM(WIN_OS)), then JavaScriptCore/interpreter/RegisterFile.h  
wants to use the roundUpAllocationSize function, which is only defined  
when ENABLE(ASSEMBLER) is true.


Obviously I could play around with doing things like enabling JIT, but  
I'm kind of wondering what my options are in terms of what is portable  
beyond the Apple ports, and what might be the best option for the wx  
port at this point in time. Any advice would be greatly appreciated! :-)


Thanks,

Kevin

Re: [webkit-dev] [GTK]Scroll deficiency

2009-03-26 Thread robert
I think maybe webkit does not refresh the page when scroll.

So, i trace the flow of webkit when scroll event fired.

In function
ChromeClient::repaint()

If i mask
// if (contentChanged)

all the problem is gone when scroll page.

Even though the page refresh ok when scroll follow upon, but refresh
the page everytime when scroll, i think it's inefficiency.

Any other better way to resolve this problem ?

Also i want to know why the contentChanged variable is false when
scroll the page, actually the content of the page was changed when scroll. I
am confused.

Appreciate any clues!

Thanks.

 The easiest way to reproduce is to go to the http://planet.webkit.org and
 try to scroll up/down the page using the scroll bar.  After a short while
 you will find areas of the page not rendered.
