963366 - Hide navigator.requestWakeLock and MozWakeLock from the web except on Firefox OS

Status: RESOLVED FIXED

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

Description

[(no longer active)]

navigator.requestWakeLock and MozWakeLock only do something useful in Firefox OS, but they are currently exposed to all platforms unconditionally.  The WebIDL has a [Func="Navigator::HasWakeLockSupport"] attribute which may trick people into believing that these names are not exposed in some places but that function only makes sure that it can instantiate the nsIPowerManagerService service, which is available everywhere.

Kan-ru, is there any reason why we should not do this?  If not, are you interested in taking this bug?

Thanks!

We'll want this soonish, to prevent web pages from having the ability to prevent the screen saver from turning on in non-B2G builds.

mochitest-browser test can't use SpecialPowers.pushPermissions without this fix.

Was disabled entirely in bug 843893. I think we should at least run a subset of these tests.

An update to test_interfaces.html (and a review from a DOM peer) would be needed.

Please use a [Pref] attribute in the webidl instead.

Also, can you please add a test which makes sure that navigator.requestWakeLock is unavailable in non-gonk platforms?
