Hi Priyanka,
Thanks for the explanation. :)
Then, now I need to search for the SDK for WebKit (or Safari) on Windows and Linux for making test plugins for understanding/watching how it works in real. :)
Thanks again!

Hi Seokbae
In the below mentioned link, there are different plugins provided (specific for the browsers), because of the
The developer develops/debugs the plug-in on a Software Development Kit (SDK) and test the plugins for the popular Browser Engines
2008/4/15 SON SEOK BAE <sbson at kt.com>:
Thanks Darin and Priyanka!
I didn't know that Firefox and Safari share the plugin programs before.
(Well, I thought they were not exactly the same, even though they were pretty similar..)
Why did I think like that? Well..
For example, Flash player..
http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash&P2_Platform=Win32&P3_Browser=Netscape
It mentioned Firefox, Mozilla, Netscape, Opera, but it didn't mention Safari...
And in the below link..
http://www.adobe.com/shockwave/download/alternates/
There are no downloadable plugins for both Safari and Firefox..
And Gecko(Firefox layout engine) supports 3 types of installation methods -- one of them provides installtions APIs (such as initInstall, performInstall, etc, but webkit doesn't seem to support those APIs..
So, I thought Safari (Webkit) supports the diffent way of installation method.
Those are the reason why I concluded that Safari and Firefox (or WebKit and Gecko) didn't share the plugins.
But, surpringly to me, they share the same plugins in real. :)
Thanks again!

The plugins are designed based on the platform, not based on the BrowserEngine.
Whether the BrowserEngine is Safari or Mozilla or Netscape, the same plugin should work if both the plugin and the BrowserEngine have followed the Netscape Gecko NPAPI standards.
Just that there are certain rules for various platforms.
MS WINDOWS :
-- plugins subdirectory, should be the same directory as the browser application
-- plugin should have its own installer to modify the windows registry keys
-- Plug-ins must have a 8.3 filename beginning with NP and ending with ".DLL"
MacOS:
-- On the Mac OS platform, the Plug-ins folder is located in the same folder as the browser application.
-- Plug-ins are identified by file type NSPL.When the browser starts up, it searches subfolders of the Plug-ins folder for plug-ins and follows aliases to folders and NSPL files.
-- Plug-in filenames must begin with NP
-- The MIME types supported by a plug-in are determined by its resources.
Unix:
-- On Unix, the plugins directory is set by the environment variable ${MOZILLA_FIVE_HOME}/plugins.
-- Plug-in filenames must begin with NP and ends with ".so"
-- To determine the MIME types of the plug-ins, the browser loads each plug-in library and calls its required NPP_GetMIMEDescription entry point.
Do correct me in case i have mentioned anything wrong.

There are not different plug-ins for Safari and Firefox on Windows.
Netscape-style plug-ins like Flash work in both browsers.
I don't know what the answer is on Linux.
Sorry I didn't answer all three of your questions, but that's the
answer to the first.

Sorry, there is not.
I've been thinking of writing some documentation about how to work
with HashSet and HashMap but this is the first request I've seen for it.
Note that HashSet is currently intended for use only inside
JavaScriptCore and WebCore, not in applications.
I don't know what "Webkit 3.0 drop" is, so I'm not sure how that
affects things.

The accepted process for patch review and committing is to open a bug on
<https://bugs.webkit.org/> and attach the patch with the "review+" flag set.
Please create a bug and attach the patch there.

You may want to fix this as well as it could cause crashes later. Please file
a separate bug for this issue.
Thanks!

The work has been largely done by folks at Trolltech, and I think
they're including WebKit in the Qt distribution itself starting with
Qt 4.4.
Those of us working cross-platform or on other platforms are trying to
contribute by keeping the TOT building on Qt, using the buildbot.
I haven't heard any talk of nightlies.
I found some info at <http://trolltech.com/webkit/webkit-announce/>, <http://labs.trolltech.com/page/Projects/Internet/WebKit

Patches for review should go in bugs.webkit.org, but I think it's
worth mentioning a couple problems I see immediately.
This incorrectly removes the "protected" for non-GCC compilers and in
fact may not even compile there because __GNUC__ is not defined and
there's no check of it. And the check here says "> 4", which means the
protected is included only for GCC 5 and newer.

#include <JavaScriptCore/JavaScript.h> to avoid the dependency on
CoreFoundation. It won't make testapi.c compile as that currently
exercises the two CoreFoundation-specific convenience functions in the
JavaScriptCore API.
