AFAIK, you should make test cases for new features. Do you prepare test cases for this feature ?

Note, the patch doesn't match the current draft (missed the additions to window and workers), and since the draft may still change (based on some comments in the mailing list), things should be webkit prefixed.

(In reply to comment #11) > Note, the patch doesn't match the current draft (missed the additions to window > and workers), and since the draft may still change (based on some comments in the mailing list), things should be webkit prefixed. I'm going to add window part patch very soon. And could you explain what prefix mean? I understand that is "-webkit-" prefix, but I'm not sure because I haven't seen events have a prefix. Did you mean prefix is like "-webkit-onbatterystatus" and "-webkit-batterystatus"? Thank you for your comment.

(In reply to comment #12) > I understand that is "-webkit-" prefix, but I'm not sure because I haven't seen events have a prefix. > Did you mean prefix is like "-webkit-onbatterystatus" and "-webkit-batterystatus"? Events do have prefixes. http://dev.w3.org/2006/webapi/DOM-Level-3-Events/html/DOM3-Events.html#extending_events-prefixes So, if you add support for onfoo listener, it would be, I think, onwebkitbatterystatus and the event type would be webkitbatterystatus.

No, i is the standard name for a simple loop index in a case like this, and this is correct style for WebKit. >> Source/WebCore/dom/BatteryStatusController.h:43 >> + void didChangeBatteryStatus(bool isPlugged, float level); > > Prefer enums to booleans.

Same as above. This is right, not wrong.

Leandro, are you a WebKit reviewer?

Comment on attachment 97938 [details] Add mock class for client and change event name to 'webkit' prefix adding. Per Darin's comments, I'm resetting the flags to '?'.

(In reply to comment #19) > Leandro, are you a WebKit reviewer? I'm not. However, I'm trying to help out and informally reviewing EFL-related patches; this one got in the mix because I happen to be watching people that often submit patches to that port. I'm setting r- as a suggestion from eseidel, so that these patches do not appear on http://webkit.org/pending-review and as a precaution so that reviewers unfamiliar with EFL don't review/rubber-stamp patches that might end up having to be rolled out. For these reasons, from now on I'll only r- EFL-related patches. I've already reset the flags to '?'. Regarding your comments, thanks -- I didn't know about old compilers getting confused with <T1<T2>>, the boolean/enum choice, and 'i' being an OK identifier for simple loops. I usually try to copy the style found on other files, but I've seen some violations (specially on older code) in the past so I try to refer only to the guidelines. Maybe I should file bugs to add notes about these on the coding style guidelines?

(In reply to comment #21) > Regarding your comments, thanks -- I didn't know about old compilers getting confused with <T1<T2>>, the boolean/enum choice, and 'i' being an OK identifier for simple loops. Sure, would be good to have those in the style guidelines. Except probably for the <X, <Y>> one, because that’s more of a C++ FAQ rather than something WebKit-specific. When I say “older compilers”, I think that means almost all compilers with only a few exceptions of quite-new ones. But we should keep an eye on which compilers we have to compile with. Would be nice to get rid of that once we require support only for the new ones.

I'm not sure that it matters, but I'm curious why you made the choice to go up through the WebKit layer instead of down through WebCore platform. For the other clients it is done to that it can be sandboxed. Not sure if that is important here. It also might make our WebKit2 code a bit more nicely separates as there are multiply ports of that "port".

Not sure if that is important here. It also might make our WebKit2 code a bit more nicely separates as there are multiply ports of that "port". I almost fix according to your comment. And, In my opinion, a client interface have to be referenced by all port. So, core part is a right position for client interface to me. Don't you think about that? Thank you for your comment.

Created attachment 99940 [details] Add events for the revised spec. http://dev.w3.org/2009/dap/system-info/battery-status.html

Created attachment 129681 [details] Patch. I have an issue about this patch. Battery Status API has to be added under the Navigator class, but there is no event handling logic in the navigator. So I implemented event listener handling logic to the BatteryManager, because I didn't have other choice, but I think this is not good to add event listener to the Battery Status API. I think navigator needs event listener handling logic like a DOMWindow. Leave some comments about this please. Thank you.

Created attachment 129806 [details] Patch. I updated the test patch yesterday - sorry about the delay in doing so. I would need your comments for the issue mentioned below. Battery Status API needs to be added under the Navigator class, but there is not any event handling logic there. Therefore, because I have no other choice, I have implemented the necessary event handling logic in the BatteryManager.
