1222720 - Report additional information when service worker event handler throw

Status: NEW

(Core :: DOM: Service Workers, defect, P3)

Description

[Ben Kelly [:bkelly, not reviewing]]

In bug 1217909 I am making service workers report uncaught exceptions and syntax errors to the console reliably.  It would be nice to provide some additional information in a secondary console line, though.  For example:

1) Throwing in the 'fetch' handler should report the FetchEvent.request.url value.
2) Throwing in the 'install' handler should report the service worker scope and indicate install was aborted.
3) Throwing in the 'activate' handler should report the scope and warn that the service worker is still active.

asuth: any objection if we unassign you and backlog this?

Perry, is this bug relevant to the discussion at all hands about improving details in error messages? Could these be some low hanging fruits when we split up the bugs for each of the errors?

Yeah, I think this is relevant and would help debugging. I think the classification of error messages in the bug description is a good start.
