Bug 27603 – updating Document.idl to match HTML5 spec: domain read-write and access to getSelection

• Status: UNCONFIRMED
• Component: WebCore Misc.

[Luke Kenneth Casson Leighton]

carrying on from discussion in https://bugs.webkit.org/show_bug.cgi?id=27434 comment https://bugs.webkit.org/show_bug.cgi?id=27434#c3 suggests that the domain property be made read-write and that access to getSelection be made universal to all bindings, to match the HTML5 specification.

It doesn't seem necessary to have this be #if'd any more.

The comment doesn't add anything.

Your ChangeLog entry again contains tabs that will make our pre-commit hook unhappy.

 ah... oh?  oh, what, because the [ConvertNullToNullString] gets ignored by bindings generators that don't need it?  oh, ok.  great.  less code!

 achhh, yes, that's vi messing up (ok - me messing up using vi) sorry.  now i know, i've done s/^I/    /g but there may be a couple of entries still with tabs, i'll try to find them.

 ahh, yes it does.  look carefully at the original file, and you
 can see that getSelection() _used_ to be commented
 as a "Mozilla Extension".

 if you remove only the #ifdef, and don't provide a comment,
 it looks like getSelection() is an IE Extension (not an
 HTML5ism) because that's the commented-block above it.


        // IE extensions

                 attribute [ConvertNullStringTo=Undefined, ConvertNullToNullString] DOMString charset;
        readonly attribute [ConvertNullStringTo=Undefined] DOMString defaultCharset;
        readonly attribute [ConvertNullStringTo=Undefined] DOMString readyState;

        Element            elementFromPoint(in long x, in long y);

        // HTML 5
        DOMSelection       getSelection();

        // Mozilla extensions

        readonly attribute [ConvertNullStringTo=Null] DOMString characterSet;


 looking _further_ down the Document.idl file, you can see
 that there is in fact a comment "// HTML 5" already in there:

        // HTML 5
        NodeList getElementsByClassName(in DOMString tagname);


 so, anticipating that "HTML 5" is acceptable, because it's already
 _in_ the file, i'm resubmitting a patch which contains the exact
 same comment "HTML 5".

 the alternative is to move the function getSelection() to somewhere
 which would only confuse people.

I believe getSelection is intentionally avoided for Obj-C bindings, but I"m not sure.  Please have an Apple person, like Mark Rowe or Tim Hatcher comment as to if this change is correct or not.

Removing my review.
