1102372 - if navigator.mozId.watch triggers a password prompt, onready never fires

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: FxA, defect)

Description

[(not reading bugmail) Nick Desaulniers [:\n]]

Due to https://bugzilla.mozilla.org/show_bug.cgi?id=1028398, navigator.mozId.watch will trigger a PW prompt.  If the closes this dialog box, onready never fires.  This makes implementing an authentication scheme with FxA difficult, since usually I would wait for onready before trying to contact the verifier (since network requests seem to fail during app start up), but now there's the possibility that onready is never called.

If the user does enter their password, onlogin fires, then onready.  This seems in line from the case where the user has been logged into this app before.

A simple workaround: ignore onready(). watch() will result in either onlogin() or onlogout() firing, so you can use the first call to either to trigger your onready(). FxA inherited onready() from Persona, and it doesn't map to FxA-on-FxOS meaningfully. You can see how redundant it is here (doReady() ends up firing onready()):
