We use else-where to avoid the inline comment. What's the advantage of an extra variable on the stack and passing a non-null pointer over the inline comment "ignored exception" ? 702938 4 159912 cmarcelo 2012-08-23 06:39:59 -0700 Comment on attachment 159912 Patch View in context: https://bugs.webkit.org/attachment.cgi?id=159912&action=review >>> Source/WebKit/qt/Api/qwebelement.cpp:763 >>> + return JSC::Bindings::convertValueToQVariant(toRef(state), toRef(state, evaluationResult), QMetaType::Void, &distance, /*exception*/0); >> >> Use "JSValueRef* ignoredException = 0;" then pass it on the function.

It is a null pointer. Effectively it will be the same than passing 0. It's a tradeoff between one more pointer in the stack and a variable name versus having the inline comment. I tend to choose the first option in those cases, but YMMV. 707277 5 159912 hausmann 2012-08-29 03:49:21 -0700 Comment on attachment 159912 Patch View in context: https://bugs.webkit.org/attachment.cgi?id=159912&action=review >> Source/WebCore/bridge/qt/qt_runtime.cpp:224 >> + int objdist = 0; > > Since you are touching this code, could you improve this name?

I tend to choose the first option in those cases, but YMMV. Ah right, it's actually a null pointer. Okay, I don't care too much about it and am fine with using your pattern. 707282 6 161175 hausmann 2012-08-29 04:01:30 -0700 Created attachment 161175 Patch Updated patch to address comments 708544 7
