r- because you missed a few addSubview cases.

It would have been nice to review the database / apache changes separately, since the rest was mechanical.

ConsolePrompt should be a subview.

What the heck is this old crap... :) we should be adding DataGrid as a subview and remove this whole function.

Noted. I suspected as much during refactoring, and will remove from the follow up.

The only other view using ConsolePrompt is the QuickConsole, which adds it as a subview. In this case, the prompt element is wrapped in another DOM element, which is why it can't be added directly as a subview.

A possible solution is to extend ConsolePrompt, creating DatabaseConsolePrompt. It would be slightly awkward swapping out View.prototype._element with the wrapper element from the derived class, but it would work:

class DatabaseConsolePrompt extends ConsolePrompt
{
    constructor(delegate, mimeType)
    {
        super(delegate, mimeType);

        let wrapperElement = document.createElement("div");
        wrapperElement.__view = this;
        wrapperElement.classList.add("database-query-prompt");
        wrapperElement.appendChild(this.element);

        delete this.element.__view;
        this._element = wrapperElement;
    }
};

We could support wrapper elements directly in the View base class with the following protected method:

class View
{
    // Protected

    insertRootElement(element)
    {
        console.assert(!this._element.parentNode);

        let oldRootElement = this._element;
        oldRootElement.__view = undefined;

        element.appendChild(oldRootElement);
        element.__view = this.
        this._element = element;
    }
};

Then:

class DatabaseConsolePrompt extends ConsolePrompt
{
    constructor(delegate, mimeType)
    {
        super(delegate, mimeType);

        let wrapperElement = document.createElement("div");
        wrapperElement.classList.add("database-query-prompt");

        this.insertRootElement(wrapperElement);
    }
};

I'll look into it. Not sure how this is used.

[Matt Baker]

Actually, wrapping the View's DOM element from a derived class will be problematic. Superclasses between View and the most derived class would be operating on a different DOM element than the one they expect.

Uh, that sounds complicated. Can we just straighten out the Database DOM tree, possibly in a followup patch if it will delay this much longer?

DatabaseContentView is being refactored under https://bugs.webkit.org/show_bug.cgi?id=150959.
