867107 - EventSource errors should log specifics to the Browser Console

Status: NEW

(Core :: DOM: Core & HTML, defect, P5)

Description

[Dirkjan Ochtman (:djc)]

In the onerror callback on EventSource objects, I just get an [object Event] if I call toString() on the event (for example, in the case of a timeout). There doesn't seem to be any other identifiable information on the object, either. See also bug 867105, where the CORS error is completely opaque as well.

Please file a spec bug. https://www.w3.org/Bugs/Public/enter_bug.cgi?product=WHATWG

http://www.whatwg.org/specs/web-apps/current-work/multipage/comms.html#the-eventsource-interface
defines that error event is a simple event.

(Made a stupid error in my description there. Will try to fix it as soon as I figure out how to create an account there.)

The opacity at the script level is intentional, but nothing prevents the console from having lots and lots of detailed debugging info.

Comment 4

[Dirkjan Ochtman (:djc)]

The spec now has notes on reporting detailed error information to the console:
