1280736 - service workers should report console service messages to debugger popup console

Status: NEW

(Core :: DOM: Service Workers, defect, P5)

Description

[Ben Kelly [:bkelly, not reviewing]]

If you debug a service worker script using about:debugging, you will get a new popup window showing the debugger and a console.  Currently service worker console reports do not show up in this console AFAICT.  We should adjust the ServiceWorkerManager::ReportToAllClients() method to include these debugger windows.

Brian or Eddy, didn't this work before? Is this a regression?

Comment 2

[Brian Grinstead [:bgrins]]

This never worked in individual worker windows.  Bug 1259603 is opened to use ConsoleEvents and expose console API messages to the frontend for those windows.  Andrea, I can't remember - what's the plan to get console service messages into the worker thread?

We don't have any plan yet. So far we dispatch Console messages generated by the console API.
We should find a way to connect ReportToAllClients to the Console API running in the worker thread.

Brian already answered Janx's question. I have nothing more to add.

Has one materialized since you wrote this? :)

Brian, do you confirm that the console API use in workers/SharedWorkers/ServiceWorkers is correctly shown in the worker debugger window?

Comment 7

[Brian Grinstead [:bgrins]]

Sorry for the delay in responding. The console API does not work for Service Workers or any workers when opening a toolbox to target that worker (this depends at least partly on Bug 1259603).  I'm going to be away for a few weeks, but if someone wanted to take over the patch in that bug it should be pretty close to landing - I think Eddy could review that code.  Landing it was held up by a test failure in the newly added test on that patch that I had trouble debugging, but we should at least get an initial landing here with or without that test.

[Brian Grinstead [:bgrins]]

OK, I'm getting close to having Bug 1259603 ready.  Let's re-purpose this bug for handling console service messages since console API messages will show up after that.

Bulk-downgrade of unassigned, untouched DOM/Storage bug's priority.

If you have reason to believe, this is wrong, please write a comment and ni :jstutte.
