WebKit Bot Watcher's Dashboard: Defer subsequent resource loads from access-restricted build bot when iteration fails to load with HTTP 401 status code

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Daniel Bates]

We should only prompt for HTTP credentials once per iteration load similar to what we do when we fetch the list of iterations (bug #127849). That is, if an HTTP 401 error occurs when we load an iteration we should notify the associated Buildbot object and update the associated queue view so that we prevent subsequent load attempt for other iterations (*) and show an "unauthorized" message on the dashboard, respectively.

(*) Such attempts would trigger an authentication dialog, which can be seen as annoying.

Isn't this too frequent? We load a lot of iterations.

I think that this would be easier to understand if it said "credentials for the buildbot" not "credentials for am iteration".

Will change before landing.
