Bug 107301 – methods on window.internals shouldn't pass in a document

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Tony Chang]

Since each internals instance is associated with a document, this isn't necessary.

Hi,

I'm working on this issue. I'll submit a patch soon.

Can you add comments in these functions explaining why they take the document argument?

No reason to add this line, it's pretty obvious to anyone who would care why there are no new tests.

Ok, but would it be interesting to put a FIXME or a simple comment?

This patch doesn't apply, so commit queue won't be able to land it.

> Source/WebCore/testing/Internals.cpp:1538

> +//(window.document, for example).

Some nitpicks:

1.There should be spaces after "//".

2. Saying why the argument was not removed is not the best comment that can be made. A person reading likely won't care about the history (and won't even know that we used to have the argument in other functions before). A comment should talk about current state, not about history.

I'd have said something like:

// FIXME: Remove the document argument. It is almost always the same as contextDocument(), with the exception of a few tests that pass a different document, and could just make the call through another Internals instance instead.
