Related to "WebKitSystemInterface.h"

Hello everyone, Just going through the WebKit source, I came across the header file: WebKitSystemInterface.h. That file is included by the Windows port of the Webkit. The other ports like wx and gtk are not including this header file at all. I am unsure about the use and purpose of this header file. I am new to the Webkit domain, so I do not have much idea about different files are their roles. Can anybody help me in this regard? I want to know about the role and need of this file as far as the porting Webkit to another platform is concerned. Thanks. Regards, Javed

Hi All, I have cross compiled WebKit for MIPS over directfb and gtk. But when i run my application GtkLauncher it hangs after some point like LIBMISC: sigmaGFXInit() [exit] 720 1280 32 (*) DirectFB/Core/WM: Default 0.2 (directfb.org) (*) Direct/Thread: Running 'EventBufferFeed' (MESSAGING, 815)... above these prints there are directfb library prints but after this it doesn't show me anything. Can anybody help me in this issue. Thanks and Regards Nishit Sharma

Anyone tried out of memory
by Mikael Tennhammar 19 Aug '08

19 Aug '08

Hi ! I made quick out-of-memory test, where I limited the available heap space for malloc (did not used the fastmalloc). The result was a Segmentation fault, I do not know if this is due to the GTK env or WebKit. But have anyone tried this before? Knows anything about it? Or is there a policy how to handle the case where a allocation is failing? /mikael

Hi, FYI: I have followed these steps in building Webkit JavascriptCore on Win32 (VC2005): <1>Install Microsoft Visual Studio 2005 and Team Suite Service Pack 1, Cygwin and related packages, QuickTime SDK; <2> Got the source from nightly build http://nightly.webkit.org/files/WebKit-SVN-source.tar.bz2. <3> Down loaded all the related support packages WebKitSupportLibrary.zip <4> Set two environment variables: WEBKITOUTPUTDIR and WEBKITLIBRARIESDIR. <5>Taken care of other settings/options in VC2005 like (Project->options->Vcproject Settings) <6> I tried building JavaScriptCore.sln in VC2005 present in (D:\cygwin\home\WebKit\JavaScriptCore\JavaScriptCore.vcproj) Compilation is successful for most of CPP files except for NumberConstructor.cpp, RegExpObject.cpp, and StringPrototype.cpp. Please check and help me out to resolve this problem. **************************************************************************** **************************************************************************** *************************************** ------ Build started: Project: WTF, Configuration: Debug_Internal Win32 ------ Performing Pre-Build Event...

Problem in Compiling Webkit on Win32

compiling GTK port
by Chris Teague 19 Aug '08

19 Aug '08

I've been unsuccessful in compiling the GTK port recently. I've tried r35788 and r35814 so far, both of them result in the following errors. Has anyone else seen this? Anyone know why the buildbot wouldn't catch this? I've tried building with both of these command lines, both result in the same error: CFLAGS="-DWTF_USE_MOBILE=1 -DWTF_USE_LOW_BANDWIDTH_DISPLAY=1" ./autogen.sh --host=arm-linux --prefix=/usr make ./autogen.sh --host=arm-linux --prefix=/usr make The errors I get: WebCore/loader/FrameLoader.cpp: In member function `void WebCore::FrameLoader::switchOutLowBandwidthDisplayIfReady()': WebCore/loader/FrameLoader.cpp:5032: error: 'class WebCore::ScriptController' has no member named clear' WebCore/loader/FrameLoader.cpp:5037: error: `instance' is not a member of `WebCore::DOMImplementation' make[1]: *** [WebCore/loader/libWebCore_la-FrameLoader.lo] Error 1

How to set a cookie for a url ?
by Andy 18 Aug '08

18 Aug '08

Hi, all, I want to set a cookie for a url, the cookie comes from a cookie string, I don't know what the format of the cookie string is supposed to be, should be like this ?? "NAME=VALUE; expires=DATE; path=PATH; domain=DOMAIN_NAME " , is there any standard to comply with ? I also have another question. In mac os x, there is a class named "NSHTTPCookie", I'm a little confused with how to use it. I googled a example like this. void setCookies(Document* /*document*/, const KURL& url, const KURL& policyBaseURL, const String& cookieStr) 64 { 65 BEGIN_BLOCK_OBJC_EXCEPTIONS; 66 67 // <rdar://problem/5632883> On 10.5, NSHTTPCookieStorage would happily store an empty cookie, which would be sent as "Cookie: =". 68 if (cookieStr.isEmpty()) 69 return; 70 71 NSURL *cookieURL = url; 72 73 // <http://bugs.webkit.org/show_bug.cgi?id=6531>, <rdar://4409034> 74 // cookiesWithResponseHeaderFields doesn't parse cookies without a value 75 String cookieString = cookieStr.contains('=') ? cookieStr : cookieStr + "="; 76 77 NSArray *cookies = [NSHTTPCookie cookiesWithResponseHeaderFields:[NSDictionary dictionaryWithObject:cookieString forKey:@"Set-Cookie"] forURL:cookieURL]; 78 [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookies:cookies forURL:cookieURL mainDocumentURL:policyBaseURL]; 79 80 END_BLOCK_OBJC_EXCEPTIONS; 81 } In the example, I guess the "cookieStr" is my "cookie string", but when I pass a string "safarname=safarivalue; expires=Thu, 2 Aug 2009 20:47:11 UTC; path=/; domain=example.com " to it, the method "cookiesWithResponseHeaderFields:" can't parse it into a cookie successfully, so can not return a cookie array, also, the method "setCookies:" failed, is there any problem with my cookie string ? Bless my poor English, I wish I make my mind clear. Thanks in advance && thanks for your time.
