Adam, did you review the patch? Could you either set it to review+, set it to review-, or state that you think someone else should review?

Sorry, my comments were a drive-by. I'll review it this afternoon.

Yes. This code resets the status string. When there is no DOM window we’re guaranteed the status string is not set. > WebCore/page/DOMWindow.cpp:767 > + if (!m_frame) > Don't we test for this above? Yes, but the code calls focus and that can trigger events and the JavaScript event handlers can do almost anything. By the time we return, m_frame may be 0. > WebCore/page/DOMWindow.cpp:803 > + if (!(page->openedByDOM() || page->getHistoryLength() <= 1 || allowScriptsToCloseWindows)) > I think this would be clearer if you pushed the ! inside the || That’s funny. I thought it was clearer not to do that! Let me think about other ways to make it clear. > WebCore/page/DOMWindow.h:418 > + inline String DOMWindow::status() const > I suspect the "inline" here is redundant. Also, we commonly put these trivial accessors on one line. The inline is not redundant because: 1) This function definition is outside the class definition, so the rule that makes all functions defined in the class definition inline does not apply. 2) And, the function is not marked inline in its declaration inside the class definition. While it’s true we often put trivial accessors on one line inside the class definition, we normally do not do that for functions outside the class definition. I think in this case it’s good to leave the function outside, making the class definition even clearer. I hope it’s OK if I leave it like this. > WebKit/win/WebView.cpp: > + *result = frame->shouldClose() ? TRUE : FALSE; > Do we not need this type conversion? I don't really understand what Windows needs here.. We definitely do not need it. TRUE and FALSE are constants that are equal to 1 and 0. Assigning from a bool works fine. The only case where "? TRUE : FALSE" or the line is needed is when all three of these are true: 1) We are converting from a boolean type that can take on values other than 1 or 0, such as Boolean or BOOL (both of which are typedefs). 2) We are converting to a boolean type that can take on values other than 1 or 0. 3) The code path is one where the value might not be 1 or 0. If either type is bool then that idiom is not needed. In this case, condition (1) is not true, so "? TRUE : FALSE" is not needed.

You mean to the change log? Frame.h has long had comments saying that various functions need to move out to the Frame subobjects. I could mention that again here. I would be happy to add something, but not sure what it should be. > > // its frame is not in a consistent state for rendering, so avoid setJSStatusBarText > > Looks like you need to update this comment text.

It's not. The code clears out the text, setting it to the null string. But the text is stored in the DOM window. If it's non-null the DOM window is guaranteed to exist.
