1474340 - Remove toolbar.toolbox XBL property and update its consumers

Status: RESOLVED FIXED

(Firefox :: Toolbars and Customization, task, P3)

Description

[:Gijs (out for now; he/him)]

With the goal of eventually removing the toolbar.xml toolbar binding from CustomizableUI, we're slowly removing parts of the binding.

In this bug, we should:

- remove https://dxr.mozilla.org/mozilla-central/rev/085cdfb90903d4985f0de1dc7786522d9fb45596/browser/components/customizableui/content/toolbar.xml#92-112 
- remove https://dxr.mozilla.org/mozilla-central/rev/085cdfb90903d4985f0de1dc7786522d9fb45596/browser/components/customizableui/content/toolbar.xml#179-190
- replace the code at https://dxr.mozilla.org/mozilla-central/rev/085cdfb90903d4985f0de1dc7786522d9fb45596/browser/components/customizableui/content/toolbar.xml#22 with:

let toolbox = this.closest("toolbox");

- remove https://dxr.mozilla.org/mozilla-central/source/browser/components/customizableui/CustomizableUI.jsm#1006


- go through browser/components/customizableui/CustomizableUI.jsm, and wherever we use the `.toolbox` property on an area node, instead reuse a local variable or argument pointing to `window`, or use node.ownerGlobal, to get a reference to `window.gNavToolbox` for the window in which the areaNode is present.

I *think* that should be enough. When fixing this bug, we should run the tests from:

./mach mochitest browser/components/customizableui/

(after rebuilding) to make sure we don't break anything.

What exactly I should write?

Can you tell about this case?

So in this particular case, the existing code does:

        let palette = aAreaNode.toolbox ? aAreaNode.toolbox.palette : null;

so you could do:

        let toolbox = aAreaNode.ownerGlobal.gNavToolbox || null;
        let palette = toolbox ? toolbox.palette : null;

In e.g. https://dxr.mozilla.org/mozilla-central/rev/085cdfb90903d4985f0de1dc7786522d9fb45596/browser/components/customizableui/CustomizableUI.jsm#1077 there is already a local variable `window`, so you can just replace:

        areaNode.toolbox.palette.appendChild(widgetNode);

with

        window.gNavToolbox.palette.appendChild(widgetNode);


And so on along the rest of the file. This is because `window` and `areaNode.ownerGlobal` point to the same object, and `window.gNavToolbox` will always point to the same thing that `areaNode.toolbox` points to right now. Does that make sense?

Hey Manish, do you need more help with this? Let me know on bugzilla if something's not clear. Thanks for working on this!

I think as your first bug this is probably a bit tricky. Try looking for bugs that are marked 'good-first-bug' instead. I saw your comment on bug 1423843 - that might be an easier bug to get started on.

This is blocking my work in bug 1356920, so I'll do this.
