Hello everyone,
I'm implementing DumpRenderTree.cpp, I've got my own WebKit port ( I'm not
using WebKit2). I'm working on Linux x86_64, with JSC/JIT, rev127214
There is an ASSERT when I call 'gTestRunner->makeWindowObject()' , I don't
know what I'm doing wrong, maybe someone can give me a hint.
Basically I'm doing what other ports are doing.
/* WebCoreSupport/WebFrameLoaderClient implements
WebCore::FrameLoaderClient interface */
void
WebFrameLoaderClient::dispatchDidClearWindowObjectInWorld(DOMWrapperWorld*
world)
{
SharedPtr<WebFrameLoadDelegate> frameLoaderDelegate =
m_webFrame->webView()->webFrameLoadDelegate();
if (frameLoaderDelegate)
{
Frame* coreFrame = core(m_webFrame);
ASSERT(coreFrame);
if( world == mainThreadNormalWorld() )
{
JSGlobalContextRef context =
toGlobalRef(coreFrame->script()->globalObject(world)->globalExec());
JSObjectRef windowObject =
toRef(coreFrame->script()->globalObject(world));
ASSERT(windowObject);
frameLoaderDelegate->didClearWindowObjectInWorld(m_webFrame,
context, windowObject);
}
}
}
/* In DumpRenderTree.cpp */
void FrameLoaderDelegate::didClearWindowObjectInWorld(WebFrame*,
JSContextRef context, JSObjectRef windowObject)
{
JSValueRef exception = 0;
assert(gTestRunner);
gTestRunner->makeWindowObject(context, windowObject, &exception);
assert(!exception);
}
The backtrace is the following :
ASSERTION FAILED: from.isCell() &&
from.asCell()->JSCell::inherits(&WTF::RemovePointer<To>::Type::s_info)
WebKit/Source/JavaScriptCore/runtime/JSCell.h(361) : To

I've compiled GTK port and tested DumpRenderTree, it works without any
problem.
