Patch for a build break due to the disabled() funciton

There is a build break due to the disabled() when wml is enabled. It seems that this break comes from the Bug 35056 - Disabled menu options are still submitted. 

WMLOptionElement class is a child class of OptionElement class as below. So, if a virtual function is added to OptionElement, WMLOptionElement class should defines that function as well.

  class WMLOptionElement : public WMLFormControlElement, public WMLEventHandlingElement, public OptionElement {



My modification is as below,

--- WebCore/wml/WMLOptionElement.h      (revision 56658)
+++ WebCore/wml/WMLOptionElement.h      (working copy)
@@ -41,6 +41,8 @@ public:
     virtual void childrenChanged(bool changedByParser = false, Node* beforeChange = 0, Node* afterChange = 0, int childCountDelta = 0);
     virtual void parseMappedAttribute(MappedAttribute*);

+    virtual bool disabled() const { return false; };
+

I think diabled() should be added to WMLOptionElement.h.

Thank you,
Gyuyoung Kim.

I'm not sure that's right. Is it true that WML option elements can't be disabled? We can follow up with another patch if the WML behavior is wrong, I guess. r=me

When wml feature is enabled, there is a build break as below,

WebCore::QualifiedName&, WebCore::Document*, bool)’:

------------------------------------------------------------------------------

I didn't check if the WML behavior is wrong. But, I think we need to avoid a build break for now.
I will report if WML option elements can't be disabled or not again. If I am wrong, please let me know. 

Thank you.

Patch for a build break due to the disabled() function   

Sorry for my frequent patches, I am not good at making a patch yet.

I found one more build break because of  Bug 36177 -  Multiselect Popup - Listbox click simulation.
(https://bugs.webkit.org/show_bug.cgi?id=36177)

The patch add a virtual function to SelectElement.h as below,
   virtual void listBoxSelectItem(int listIndex, bool allowMultiplySelections, bool shift, bool fireOnChangeNow = true) = 0;

It seems the patch of bug didn't consider wml. I add a virtual function to WMLSelectElement.h.

OK.  Your ChangeLog does not mention WebCore/wml/WMLSelectElement.h, but it's OK.

[Gyuyoung Kim]

Thanks. When I push another patches, I will write changelog correctly.

My patch is wrong ?  Should I make a patch again ?

[Eric Seidel (no email)]

Your patch looks fine.  Looks like Adam or I broke the commit-queue.  I'll investigate.

Actually, looks like you modified the "reviewed by" line:
+        Reviewed by NOBODY(OOPS!).

the default template is:
+        Reviewed by NOBODY (OOPS!).

The scripts aren't smart enough to know the difference between "NOBODY(OOPS!)" and an intentionally specified reviewer.

I suggest just regenerating the ChangeLog from prepare-ChangeLog, which will both fix your reviewed by line to be the default as well as add the information about WebCore/wml/WMLSelectElement.h

Sorry our scripts are so troublesome.

There was also a problem in webkit-patch's validatereviewer.py step which I've fixed.
