[webkit-dev] DOM Serialization?
-- Forwarded message -- From: ZHOU Xiao-bo zhxb.u...@gmail.com Date: 2010/1/24 Subject: Re: [webkit-dev] DOM Serialization? To: Christopher White skullkn...@gmail.com I think you can do that, if you don't care about the strick definition of serialization. Actually, a Node is composed of Attrs which are key, value pairs. And 'key' and 'value' are strings. So, you can just use TLVs to store the Node's type and Attrs. You can either ignore its non-string member variables, because you can rebuild them through Attrs or store them in TLVs too. As for the implimentation, you can write a two friend functions for every class derived from Node to make serialization and deserialization. And the function 'createmarkup' may give you some clue. BTW: the DOM Level 3 defines Load Save interface of DOM, does WebCore impliment that. 2010/1/22 Christopher White skullkn...@gmail.com Is it possible to save the DOM resulting from the parsing of HTML / CSS into a file and then read it back instead of re-parsing the HTML (similar to Java object serialization). Does it save any time or is it a wash? I know there is a dump render tree function but does it save everything you need so that you can re-render the HTML page w/o the original HTML / CSS files? ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
Re: [webkit-dev] build-webkit but not all of it
Use autogen and configure? 2009/10/27 Alexander Cohen naft...@me.com Is there a cmd to run if i only want to rebuild WebCore but not touch any of the other frameworks, something similar to build-webkit? thx AC ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
Re: [webkit-dev] Windows Multithread issue
There are so many classes containing static hashmap, such as string. Cache is a singleton and the contents it caches is not thread-safe. As for js, JSGlobalOjbect is linked by a list. 2009/6/16 John Abd-El-Malek j...@google.com Yes it's possible. The Chromium port runs web views in different processes. You can look at the design docs and source to see how it's done, that should give you an idea of what you have to do this on different threads. 2009/6/15 熊科浪 xiongkel...@hotmail.com hi I want to develop c++ application that uses WebKit on Windows. Can I start a thread for each web view? or I must ceate every web view and handle every event in the main thread?and why?are there any plan to change it?

[webkit-dev] about hashmap staticDOMObjects
hi all:
I still don't understand the purpose of the HashMap:
static DOMObjectMap domObjects()
{
// Don't use malloc here. Calling malloc from a mark function can
deadlock.
static DOMObjectMap staticDOMObjects;
return staticDOMObjects;
}
what kind of DOMObjects should be stored in it? And why?
I searched the source codes and I found that these classes below will do
that:
Document, Event, HTMLCollection, XMLHttpRequest, CanvasGradient,
CanvasPattern, CanvasRenderingContext2D, DOMCoreException,
DOMImplementation, DOMParser, EventException, History, NamedNodeMap,
NodeFilter, NodeIterator, NodeList, Range, RangeException, TreeWalker,
XMLHttpRequestException, XMLSerializer, Clipboard
but what's the reason? Is it because these classes are essentially simple
and just acting as a tool?
thanks a lot

Re: [webkit-dev] about hashmap staticDOMObjects
oh, I got an idea:
Is it because these domobjects doesn't belong to a Document, so they can't
be
stored in
static NodePerDocMap domNodesPerDocument()
{
ASSERT(JSLock::lockCount());
static NodePerDocMap staticDOMNodesPerDocument;
return staticDOMNodesPerDocument;
}

[webkit-dev] about WTF::HashMap::iterator
hi all:
WTF::Hashmap::iterator uses WTF::HashTable::iterator as its m_impl.
When you call 'remove( oldIter )', the current 'iter' may be changed. And
it's not about memory reallocation or element shift, but it's because the
member variable 'm_table' in WTF::HashTable::iterator may become NULL
if there is only one entry in the HashMap before you call remove( olditer ).
So, how can I delete an element of a HashMap when I traversing the
container? e.x.
while( iter ) {
oldIt = iter;
++iter;
remove( oldIT ); // not always safe
}
thx

[webkit-dev] about referencing objects between JavaScriptCore and WebCore
dear all: I have a question about the objects referencing between Javasciptcore and WebCore: JSNode uses m_impl to reference a Node in WebCore. And when KJS::Collector::collect() is called the function mark() of each JSNode is invoked to keep the corresponding Node in WebCore alive in memory. The problem is: I want to seperate the memory managment of each page. To do so, I allocate a large block of memory for eache page, and delete it when loading the next page. ( I have commented out 'pagecache', 'backforwardlist' etc.) But, when it jumps back to a page which has been visited before, and a block of javascipt codes is excuted, it crashes when JSNode use m_impl to reference a Node in WebCore. The reason is m_impl is pointing an empty memory block. I used gdb to examine the value of m_impl, and I found that it likely contained an address of a Node created when this page was loaded the first time. My question is: how do JavaSciptCore maintain the JSNode(s) to make them reference the old Nodes? And how can I force JSNode's m_impl reference the new Node? Do I make myself clear? Appreciate any clues! thx! ZHOU Xiao-bo ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
