Minutes approval

Approve minutes from 31 October 2013 http://lists.w3.org/Archives/Public/public-device-apis/2013Nov/att-0009/minutes-2013-10-31.html

RESOLUTION: Minutes from 31 October 2013 are approved

Test Updates - Proximity, Light


fjh: Zhiqiang added some IDL harness tests and initial value checking tests for Ambient Light Events [1] and Proximity Events [2]
... what comes next?
... see http://lists.w3.org/Archives/Public/public-device-apis/2013Nov/0014.html

anssik: this should now be fully aligned with specification but have not been able to review

… upon review can merge them

fjh: does this mean you have an implementation as well

anssik: cannot say right now about our plans

… not sure webkit implementation is shipping, Samsung people might know latest

<anssik> http://www.w3.org/2009/dap/wiki/ImplementationStatus#Proximity_Events

fjh: I would like to get implementers looking at the test cases and see if we can get interop started

anssik: should probably check with Kihong Kwon

fjh: we need at least two real implementations to exit CR

anssik: vibration is turned on Chrome but not the others as far as I know

fjh: does it match latest, 2nd CR of Vibration

anssik: yes, it matches the latest (afaik)

… Gecko may need revision

… Justin Lebar has moved roles, so need to know who is working on this now

fjh: I'll check offline

anssik: I can check at TPAC about implementations and testing for Proximity, Light, Vibration

gmandyam: possible concern that device orientation may be changed to use promise based approach, yet some DAP specifications have not advanced.

fjh: Media capture TF has elected not to use promises

gmandyam: sys apps and web crypto have incorporated promises

fjh: right

gmandyam: issue is when promises will be stable and finalized

<anssik> btw. IE11 added support for Device Orientation Events http://msdn.microsoft.com/en-us/library/ie/dn433240(v=vs.85).aspx

gmandyam: other issue is functionality of device orientation, do we need consistency?

… android also supports device orientation events

… this microsoft approach is argument against a change from the event method we use in DAP, already deployed



<trackbot> ISSUE-156 -- add the [Clamp] attribute to the argument of the vibrate method -- open

<trackbot> http://www.w3.org/2009/dap/track/issues/156

decided to defer on list since the underlying specification is not stable

<gmandyam> To summarize: Changing DeviceOrientation from an EventTarget approach would likely by too large a change to be supported by implementations, given e.g. IE support for the spec as it stands.

close ACTION-670

<trackbot> Closed ACTION-670.


<trackbot> ACTION-670 -- Anssi Kostiainen to Review issue-156 and add clamp to vibration specification -- due 2013-11-07 -- CLOSED

<trackbot> http://www.w3.org/2009/dap/track/actions/670

Network Service Discovery

Updated implementation using promises, http://lists.w3.org/Archives/Public/public-device-apis/2013Nov/0003.html (Jean-Claude)

Plan for PING privacy review in January

fjh: Rich will participate PING review, others welcome
... we need to explain the spec, so anything we can do to clarify would be useful

<gmandyam> Frederick - have to drop out. Hope to see everyone at TPAC.

Also arranging security issues discussion with WebAppSec to be followed by review

fjh: this will be a call, not TPAC

cannot discuss without Rich on call

cathy: stuck on whether to go forward with device support

fjh: waiting on Rich to respond to that thread
... will ask Rich offline
