867105 - EventSource connections should log error information to the Browser Console

Status: NEW

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

Description

[Dirkjan Ochtman (:djc)]

I was experimenting with server-sent events today. When I connect to a different server (actually the same server, but different port and with/without FQDN), the EventSource throws a generic error ("connection to <URL> was interrupted while the page was loading") only once the first event is sent by the server. I'm guessing the timing is related to bug 780396, as well. It would be pretty useful to have a specific error message clarifying that it's a CORS problem.

The script-detectable exception message itself shouldn't say much, but the console can have lots of detailed information.

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

Mass bug change to replace various 'parity' whiteboard flags with the new canonical keywords. (See bug 1443764 comment 13.)
