Status: RESOLVED INVALID

(DevTools :: Debugger, defect)

Description

[Panos Astithas (he/him) [:past] (please ni?)]

Contributor ovietago discovered this bug and made the following notes that I'm copying below. CCing Eddy as it looks related to the recent loader changes and DevToolsUtils.js.



Version: 31.0 Firefox Beta
Linux x64

To Reproduce:
- Get the Addon SDK 1.16 (Latest)
- Generate an empty add on in a folder

Use this as a main.js file:
//===============================================
var buttons = require('sdk/ui/button/action');


var button = buttons.ActionButton({
    id: "page-worker-Trigger",
    label: "Tigger Page Worker",
    icon: {
        "16": "./icon-16.png",
        "32": "./icon-32.png",
        "64": "./icon-64.png"
    },
    onClick: handleClick
})

function handleClick(state){
    let pageWorkers = require("sdk/page-worker");

    let worker = pageWorkers.Page({
        contentScript: "self.port.emit('loaded')",
        contentURL: "http://10.100.10.16/testPage/"
    });

    worker.port.on('loaded', function(){
        console.log("loaded");
    })
    console.log(worker);
}
//===============================================

The images can be found : https://developer.mozilla.org/en-US/Add-ons/SDK/Tutorials/Getting_started

- Launch firefox with:
$ cfx run -o -b /opt/firefox/firefox

- Trigger one time the addon by clicking on the firefox icon on the upper right side
- Go on about:addons
- extensions, select your extension, debug

- look for the page worker module
- put a breakpoint on line 162
- Click on the firefox addon to trigger the listener.

You should get this stack trace:

Thanks for cc'ing me Panos. Will take a look at it asap.

Comment 2

[Eddy Bruel [:ejpbruel]]

This doesn't look related to any changes I made. I also won't have time to look into it any time soon, so unassigning myself.

Closing as I believe this relates to legacy addons. If this is still relevant, feel free to re-open.
